Description

ＭＴ型ストラドルドビークルMT type straddle vehicle
　本発明は、ＭＴ型鞍乗型車両に関する。 The present invention relates to an MT type saddle-mounted vehicle.
　ＭＴ型鞍乗型車両として、例えばアイドリングストップを行う自動二輪車が知られている（例えば特許文献１）。例えば、特許文献１に示す自動二輪車は、アイドリングストップの許可条件を満たしている場合、アイドリングストップ要求スイッチの操作によりアイドリングストップを開始する。 As an MT type saddle-mounted vehicle, for example, a motorcycle that stops idling is known (for example, Patent Document 1). For example, the motorcycle shown in Patent Document 1 starts idling stop by operating the idling stop request switch when the idling stop permission condition is satisfied.
特許第６５８２４４１号公報Japanese Patent No. 6582441
　特許文献１に示す自動二輪車は、許可条件の一つとして実質的に停車している場合に、アイドリングストップのために設けられたアイドリングストップ要求スイッチの操作を求める。
　アイドリングストップを行うＭＴ型鞍乗型車両では、アイドリングストップ機能の利便性を高めることが望まれている。本発明の目的は、ＭＴ型鞍乗型車両のアイドリングストップ機能の利便性を高めることである。 The motorcycle shown in Patent Document 1 requires the operation of the idling stop request switch provided for idling stop when the motorcycle is substantially stopped as one of the permission conditions.
In MT type saddle-mounted vehicles that perform idling stop, it is desired to enhance the convenience of the idling stop function. An object of the present invention is to enhance the convenience of the idling stop function of the MT type saddle-mounted vehicle.
　本発明者らは、ＭＴ型鞍乗型車両におけるアイドリングストップ機能について利便性の観点から検討した。例えば特許文献１に示す自動二輪車において、アイドリングストップを実施するためには、車両を停止させることが求められる。本発明者らは、敢えて走行中にアイドリングストップを可能とする手段を検討した。本発明者らは、ＭＴ型鞍乗型車両が走行している場合に、運転者が車両を停止させる前に行なう可能性のある操作に応じてエンジンの燃焼動作を停止することを考えた。
　例えば、ＭＴ型鞍乗型車両の走行中に多段変速装置をニュートラル状態に変更し且つクラッチを接続する操作は、運転者がＭＴ型鞍乗型車両を停止させる前に行われる可能性がある。多段変速装置がニュートラル状態の場合、クラッチが接続されても、エンジンからの動力は駆動輪へ伝達されない。この作用を利用して運転者は、ＭＴ型鞍乗型車両の走行中に多段変速装置をニュートラル状態に変更し且つクラッチを接続する操作を実施する可能性がある。本発明者らは、走行中における多段変速装置とクラッチの操作を燃焼動作の停止の条件として利用することを検討した。 The present inventors have examined the idling stop function in an MT type saddle-mounted vehicle from the viewpoint of convenience. For example, in the motorcycle shown in Patent Document 1, in order to carry out idling stop, it is required to stop the vehicle. The present inventors have deliberately examined means for enabling idling stop while driving. The present inventors have considered that when an MT-type saddle-mounted vehicle is running, the combustion operation of the engine is stopped according to an operation that the driver may perform before stopping the vehicle.
For example, the operation of changing the multi-speed transmission to the neutral state and engaging the clutch while the MT-type saddle-type vehicle is running may be performed before the driver stops the MT-type saddle-type vehicle. When the multi-speed transmission is in the neutral state, the power from the engine is not transmitted to the drive wheels even if the clutch is engaged. Utilizing this effect, the driver may change the multi-speed transmission to the neutral state and perform an operation of engaging the clutch while the MT type saddle-mounted vehicle is running. The present inventors have studied the use of the operation of the multi-speed transmission and the clutch during traveling as a condition for stopping the combustion operation.
　本発明者らは、エンジンの燃焼動作を停止する場合のＭＴ型鞍乗型車両の走行の条件についても検討した。ＭＴ型鞍乗型車両の走行中に操作に応じて燃焼動作が停止した後、且つＭＴ型鞍乗型車両の走行が停止する前に、運転者が再びエンジンを始動するとともに多段変速装置の状態を非ニュートラル状態に変更してＭＴ型鞍乗型車両を加速したい場合がある。
　ＭＴ型鞍乗型車両に使用される多段変速装置は、シーケンシャルタイプである。シーケンシャルタイプの多段変速装置には、１速と２速の間にニュートラルが配置されるリターンタイプと、ニュートラルと２速の間に１速が配置されるボトムニュートラルタイプとが含まれる。ボトムニュートラルタイプは、ニュートラル状態でシフトアップ操作を受けると状態が１速に遷移する。１速でシフトアップ操作を受けると状態が２速に遷移する。２速でシフトアップ操作を受けると状態が３速に遷移する。３速でシフトアップ操作を受けると状態が４速に遷移する。４速でシフトアップ操作を受けると状態が５速に遷移する。多段変速装置は、ニュートラル状態から、操作を受ける毎に、途中の変速段を飛び越すこと無く順に遷移するように構成される。リターンタイプでは、ニュートラル状態でシフトアップ操作を受けると操作の向きに応じて状態が１速又は２速に遷移する。１速及び２速以降の遷移については、ボトムニュートラルタイプと同じである。つまり、シーケンシャルタイプの多段変速装置は、少なくとも1速以外の変速段について、途中の変速段を飛び越すこと無く、操作を受ける毎に順に遷移するように構成される。
　運転者が再びエンジンを始動する場合、停止していたエンジンが始動した時の回転速度及び１速の変速比又は２速の変速比に対応する走行速度と、エンジンが始動した時の実際の走行速度との間に大きな差がある場合がある。しかし、多段変速装置を例えばニュートラル状態から４速以上に遷移させようとすると、操作に長い時間が掛かりやすい。
　そこで、本発明者らは、ＭＴ型鞍乗型車両が１速アイドリング速度から３速アイドリング速度までの区間の少なくとも一部に相当するように設定される速度範囲で走行している場合に、エンジンの燃焼動作を停止することを検討した。即ち、本発明者らは、操作におけるニュートラル状態に近い変速段に対応する速度で、燃焼動作を停止することを検討した。
　この場合、燃焼動作を停止した後、エンジンを再加速する時に、運転者は、エンジンを再始動するとともに多段変速装置の状態をニュートラル状態から走行速度に適した１速から３速の間の何れかの変速段に遷移させる。運転者はこの後クラッチを接続状態にする。この場合、例えば多段変速装置の状態をニュートラル状態から４速以上に遷移させ、後クラッチを接続にするよりも短時間で操作を完了することができる。つまり、ＭＴ型鞍乗型車両が、短時間で加速を開始できる。 The present inventors also examined the running conditions of the MT type saddle-type vehicle when the combustion operation of the engine is stopped. After the combustion operation is stopped in response to the operation while the MT type saddle type vehicle is running, and before the MT type saddle type vehicle stops running, the driver starts the engine again and the state of the multi-speed transmission device. May be changed to a non-neutral state to accelerate the MT type saddle-mounted vehicle.
The multi-speed transmission used in the MT type saddle-mounted vehicle is a sequential type. Sequential type multi-speed transmissions include a return type in which neutral is arranged between the first and second speeds, and a bottom neutral type in which the first speed is arranged between the neutral and the second speed. In the bottom neutral type, when a shift-up operation is received in the neutral state, the state shifts to the first speed. When the shift-up operation is received in the 1st speed, the state shifts to the 2nd speed. When the shift-up operation is received in the 2nd speed, the state shifts to the 3rd speed. When the shift-up operation is received in the 3rd speed, the state shifts to the 4th speed. When the shift-up operation is received in the 4th speed, the state shifts to the 5th speed. The multi-speed transmission is configured to sequentially transition from the neutral state to each operation without jumping over the shift stage in the middle. In the return type, when the shift-up operation is received in the neutral state, the state changes to the 1st speed or the 2nd speed depending on the direction of the operation. The transition after the 1st speed and the 2nd speed is the same as the bottom neutral type. That is, the sequential type multi-speed transmission is configured so that at least the gears other than the 1st gear are sequentially transitioned each time the operation is received without jumping over the gears in the middle.
When the driver starts the engine again, the rotation speed when the stopped engine is started, the running speed corresponding to the 1st gear ratio or the 2nd gear ratio, and the actual running when the engine is started. There may be a large difference from the speed. However, when the multi-speed transmission is to be changed from the neutral state to the 4th speed or higher, it tends to take a long time to operate.
Therefore, the present inventors consider that the MT type saddle-mounted vehicle is traveling in a speed range set so as to correspond to at least a part of a section from the 1st speed idling speed to the 3rd speed idling speed. It was considered to stop the combustion operation of. That is, the present inventors have studied to stop the combustion operation at a speed corresponding to a shift stage close to the neutral state in operation.
In this case, when the engine is re-accelerated after the combustion operation is stopped, the driver restarts the engine and changes the state of the multi-speed transmission from the neutral state to either the 1st speed to the 3rd speed suitable for the traveling speed. Transition to that shift stage. The driver then engages the clutch. In this case, for example, the operation can be completed in a shorter time than when the state of the multi-speed transmission is changed from the neutral state to the 4th speed or higher and the rear clutch is connected. That is, the MT type saddle-mounted vehicle can start accelerating in a short time.
　上述したように走行中における多段変速装置とクラッチの操作を利用しつつ、燃焼動作を停止する速度を設定する。これにより、エンジンの燃焼動作の停止後に再始動した場合における加速応答性の低下を抑制しつつ、走行中でも停止予定の操作に基づいてエンジンの燃焼を停止することができる。 As described above, set the speed at which the combustion operation is stopped while using the operation of the multi-speed transmission and the clutch while driving. As a result, it is possible to stop the combustion of the engine based on the operation scheduled to be stopped even during traveling, while suppressing the deterioration of the acceleration response when the engine is restarted after the combustion operation is stopped.
　具体的には、下記３つの要件を満たしたときに、エンジンの燃焼動作が停止する。ここで、３つの要件は、（ａ）ＭＴ型鞍乗型車両の車速が、基準速度範囲内の速度であること、（ｂ）多段変速装置がニュートラル状態であること、及び（ｃ）運転者の前記クラッチレバーへの操作に応じて、クラッチが動力伝達経路を接続することである。（ａ）の基準速度範囲は、１速アイドリング速度から３速アイドリング速度までの区間の少なくとも一部に相当するように設定される。これにより、エンジンの燃焼動作の停止後に再始動した場合における時の加速応答性の低下遅れを抑制しつつ、走行中でも車両の停止予定の操作に基づいてエンジンの燃焼動作を停止することができる。従って、ＭＴ型鞍乗型車両のアイドリングストップ機能の利便性を高めることができる。 Specifically, the combustion operation of the engine stops when the following three requirements are met. Here, the three requirements are (a) the vehicle speed of the MT type saddle-mounted vehicle is within the reference speed range, (b) the multi-speed transmission is in the neutral state, and (c) the driver. The clutch connects the power transmission path in response to the operation of the clutch lever. The reference speed range of (a) is set so as to correspond to at least a part of the section from the 1st speed idling speed to the 3rd speed idling speed. As a result, it is possible to stop the combustion operation of the engine based on the operation scheduled to stop the vehicle even while the vehicle is running, while suppressing the delay in the decrease in acceleration response when the engine is restarted after the combustion operation is stopped. Therefore, the convenience of the idling stop function of the MT type saddle-mounted vehicle can be enhanced.

　クラッチは、エンジンと多段変速装置の間の動力伝達経路上に設けられる。クラッチは、運転者によるクラッチレバーへの操作に応じて、エンジンと多段変速装置の間の動力伝達を断続する。
　始動発電機は、クランク軸との間でクラッチを介さず動力が伝達されるようにクランク軸に接続される。始動発電機は、エンジンの始動時にクランク軸を駆動することでエンジンを始動させ、エンジンの燃焼動作時にクランク軸に駆動され発電する。 The MT type saddle-mounted vehicle of (1) includes an engine, drive wheels, a multi-stage transmission, a clutch lever, a clutch, a starting generator, and a control device.
The engine has a crank shaft. The engine outputs the power generated by combustion via the rotating crank shaft.
The drive wheels receive power output from the engine to drive an MT-type saddle-mounted vehicle.
The multi-speed transmission changes the gear ratio between the engine and the drive wheels in multiple stages including the neutral state according to the operation of the driver.
The clutch lever is operated by the driver's clutch.
The clutch is provided on the power transmission path between the engine and the multi-speed transmission. The clutch interrupts and disengages power transmission between the engine and the multi-speed transmission in response to the driver's operation of the clutch lever.
The starting generator is connected to the crank shaft so that power is transmitted to and from the crank shaft without a clutch. The starting generator starts the engine by driving the crank shaft when the engine is started, and is driven by the crank shaft to generate electricity during the combustion operation of the engine.
　（１）のＭＴ型鞍乗型車両の制御装置は、下記３つの要件を全て満たしたときに、エンジンの燃焼動作の停止を行う。ここで、３つの要件は、（ａ）ＭＴ型鞍乗型車両が、基準速度範囲内の速度で走行中であること、（ｂ）多段変速装置がニュートラル状態であること、及び、（ｃ）運転者の前記クラッチレバーへの操作に応じて、クラッチが動力伝達経路を接続すること、である。（ａ）基準速度範囲は、１速アイドリング速度から３速アイドリング速度までの区間の少なくとも一部に相当するように設定される。 The control device for the MT type saddle-mounted vehicle in (1) stops the combustion operation of the engine when all of the following three requirements are satisfied. Here, the three requirements are (a) the MT type saddle-type vehicle is traveling at a speed within the reference speed range, (b) the multi-speed transmission is in the neutral state, and (c). The clutch connects the power transmission path in response to the driver's operation on the clutch lever. (A) The reference speed range is set so as to correspond to at least a part of the section from the 1st speed idling speed to the 3rd speed idling speed.
　運転者が多段変速装置をニュートラル状態にし、且つクラッチを接続する操作を行った場合、運転者がＭＴ型鞍乗型車両を停止させる予定である場合が多い。即ち、多段変速装置がニュートラル状態の場合、クラッチが接続されてもエンジンからの動力は駆動輪に伝達されない。運転者は、ＭＴ型鞍乗型車両の走行中に多段変速装置をニュートラル状態に変更し且つクラッチを接続する操作を実施する場合が多い。この操作を条件の一つとして、エンジンの燃焼動作を停止することによって、ＭＴ型鞍乗型車両が走行している場合であって運転者が車両を停止させる可能性のある場合にエンジンの燃焼動作を停止することができる。 When the driver puts the multi-speed transmission in the neutral state and operates to connect the clutch, the driver often plans to stop the MT type saddle-mounted vehicle. That is, when the multi-speed transmission is in the neutral state, the power from the engine is not transmitted to the drive wheels even if the clutch is engaged. In many cases, the driver changes the multi-speed transmission to the neutral state and engages the clutch while the MT type saddle-mounted vehicle is running. By stopping the combustion operation of the engine with this operation as one of the conditions, the combustion of the engine is performed when the MT type saddle-mounted vehicle is running and the driver may stop the vehicle. The operation can be stopped.
　上記構成のＭＴ型鞍乗型車両によれば、上記基準速度範囲は、１速アイドリング速度から３速アイドリング速度までの区間の少なくとも一部に相当するように設定される。ＭＴ型鞍乗型車両は、基準速度範囲で走行している場合に、エンジンの燃焼動作が停止する。このとき、燃焼動作を停止した後、再び加速するためエンジンを再始動する場合に、エンジンを再始動するとともに多段変速装置の状態を１速から３速の間の何れかの変速段に遷移させる。基準速度範囲内で走行している場合、多段変速装置の状態を１速から３速の間の何れかの変速段に遷移させることによって、ＭＴ型鞍乗型車両を短時間で加速開始できる状態にすることができる。 According to the MT type saddle-mounted vehicle having the above configuration, the reference speed range is set so as to correspond to at least a part of the section from the 1st speed idling speed to the 3rd speed idling speed. In the MT type saddle-mounted vehicle, the combustion operation of the engine is stopped when the vehicle is traveling in the reference speed range. At this time, when the engine is restarted to accelerate again after the combustion operation is stopped, the engine is restarted and the state of the multi-speed transmission is changed to any shift stage between the 1st speed and the 3rd speed. .. When traveling within the reference speed range, the MT type saddle-type vehicle can be started accelerating in a short time by shifting the state of the multi-speed transmission to any of the speeds between 1st and 3rd. Can be.
　これにより、燃焼停止を実施する条件の一つとして走行中における多段変速装置とクラッチの操作を利用しつつ、更なる条件として走行速度を設定することができる。従って、エンジンの停止後に再始動した場合における加速応答性の低下を抑制しつつ、走行中でも停止の可能性のある操作に基づいてエンジンの燃焼を停止することができる。これにより、ＭＴ型鞍乗型車両のアイドリングストップ機能の利便性を高めることができる。 This makes it possible to set the traveling speed as a further condition while using the operation of the multi-speed transmission and the clutch during traveling as one of the conditions for stopping combustion. Therefore, it is possible to stop the combustion of the engine based on an operation that may stop even during traveling, while suppressing a decrease in acceleration response when the engine is restarted after the engine is stopped. This makes it possible to enhance the convenience of the idling stop function of the MT type saddle-mounted vehicle.
　本発明の一つの観点によれば、ＭＴ型鞍乗型車両は、以下の構成を採用できる。

　（２）のＭＴ型鞍乗型車両では、前記（ａ）から（ｃ）の条件に加え、更に（ｄ）スロットル弁が実質的に最小開度の状態である場合に、エンジンの燃焼動作が停止する。（２）のＭＴ型鞍乗型車両は、スロットル弁が実質的に最小開度であることも条件に含まれることにより、クラッチの接続が車両の停止に関連する可能性がより高い。これにより、（２）のＭＴ型鞍乗型車両の運転者がＭＴ型鞍乗型車両の停止を行う可能性がより高い場合に、エンジンの燃焼動作の停止を行うことができる。従って、（２）のＭＴ型鞍乗型車両では、アイドリングストップを行うＭＴ型鞍乗型車両において、運転者にとっての利便性をより高めることができる。 In the MT type saddle-mounted vehicle of (2), in addition to the conditions (a) to (c) above, when (d) the throttle valve is in a state of substantially the minimum opening, the combustion operation of the engine is performed. Stop. In the MT type saddle-mounted vehicle of (2), it is more likely that the clutch connection is related to the stop of the vehicle because the condition is that the throttle valve has a substantially minimum opening. Thereby, when the driver of the MT type saddle-mounted vehicle of (2) is more likely to stop the MT-type saddle-mounted vehicle, the combustion operation of the engine can be stopped. Therefore, in the MT type saddle-mounted vehicle of (2), the convenience for the driver can be further enhanced in the MT-type saddle-mounted vehicle that performs idling stop.
　本発明の一つの観点によれば、ＭＴ型鞍乗型車両は、以下の構成を採用できる。
　（３）　（１）又は（２）のＭＴ型鞍乗型車両であって、
　前記制御装置は、運転者の操作により、前記クラッチが、前記動力伝達経路を接続してから感応基準時間が経過した場合に、前記エンジンの燃焼動作を停止する。 According to one aspect of the present invention, the MT type saddle-mounted vehicle can adopt the following configuration.
(3) The MT type saddle-mounted vehicle according to (1) or (2).
The control device stops the combustion operation of the engine when the sensitive reference time elapses after the clutch connects the power transmission path by the operation of the driver.
　ＭＴ型鞍乗型車両の運転者は、例えば停止する予定がない時に、多段変速装置をニュートラルの状態とし、クラッチを接続の状態にする場合がある。（３）のＭＴ型鞍乗型車両の制御装置は、クラッチが動力伝達経路を接続してから感応基準時間が経過した場合に、エンジンの燃焼動作を停止する。感応基準時間は、ゼロよりも大きい時間である。（３）のＭＴ型鞍乗型車両では、クラッチによって動力伝達経路が一旦切断されても、感応基準時間が経過する前に、エンジンの燃焼動作を継続したまま動力伝達経路の切断状態に戻ることができる。これにより、（３）のＭＴ型鞍乗型車両では、クラッチを接続状態にする操作の後、感応基準時間の経過前に、上記クラッチについての操作を戻す操作を行なえば、燃焼動作の停止を中止できる。このため、改めてのエンジンの始動の操作を省略できる。従って、（３）のＭＴ型鞍乗型車両では、アイドリングストップを行うＭＴ型鞍乗型車両において、利便性をより高めることができる。 The driver of the MT type saddle-mounted vehicle may put the multi-speed transmission in the neutral state and the clutch in the connected state, for example, when there is no plan to stop. The control device for the MT-type saddle-mounted vehicle of (3) stops the combustion operation of the engine when the sensitivity reference time elapses after the clutch connects the power transmission path. The sensitive reference time is a time greater than zero. In the MT type saddle-mounted vehicle of (3), even if the power transmission path is once disconnected by the clutch, the engine returns to the disconnected state while continuing the combustion operation before the sensitive reference time elapses. Can be done. As a result, in the MT type saddle-mounted vehicle of (3), if the operation of returning the operation of the clutch is performed after the operation of connecting the clutch and before the lapse of the sensitive reference time, the combustion operation is stopped. You can cancel. Therefore, it is possible to omit the operation of starting the engine again. Therefore, in the MT type saddle-mounted vehicle of (3), the convenience can be further enhanced in the MT-type saddle-mounted vehicle that performs idling stop.

　本明細書では、新しいＭＴ型鞍乗型車両について説明する。以下の説明では、説明の目的で、本発明の完全な理解を提供するために多数の具体的な詳細を述べる。しかしながら、当業者には、これらの特定の詳細無しに本発明を実施できることが明らかである。本開示は、本発明の例示として考慮されるべきであり、本発明を以下の図面または説明によって示される特定の実施形態に限定することを意図するものではない。 This specification describes a new MT type saddle-mounted vehicle. In the following description, for purposes of illustration, a number of specific details are given to provide a complete understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without these specific details. The present disclosure should be considered as an example of the invention and is not intended to limit the invention to the particular embodiments set forth in the drawings or description below.
　ＭＴ型鞍乗型車両は、マニュアル多段変速装置を有する鞍乗型車両である。鞍乗型車両（ｓｔｒａｄｄｌｅｄ　ｖｅｈｉｃｌｅ）とは、運転者がサドルに跨って着座する形式のビークルをいう。鞍乗型車両としては、例えば、モペット型、オフロード型、オンロード型の自動二輪車が挙げられる。また、鞍乗型車両としては、自動二輪車に限定されず、例えば、自動三輪車、ＡＴＶ（Ａｌｌ－Ｔｅｒｒａｉｎ Ｖｅｈｉｃｌｅ）等であってもよい。自動三輪車は、２つの前輪と１つの後輪とを備えていてもよく、１つの前輪と２つの後輪とを備えていてもよい。鞍乗型車両の駆動輪は、後輪であってもよく、前輪であってもよい。また、鞍乗型車両の駆動輪は、後輪及び前輪の双方であってもよい。また、鞍乗型車両は、リーン姿勢で旋回可能に構成されていることが好ましい。リーン姿勢で旋回可能に構成された鞍乗型車両は、カーブの中心に傾いた姿勢で旋回するように構成される。これにより、リーン姿勢で旋回可能に構成された鞍乗型車両は、旋回時にビークルに加わる遠心力に対抗する。リーン姿勢で旋回可能に構成された鞍乗型車両では、軽快性が求められるため、加速の操作に対する応答性が重要視される。ＭＴ型鞍乗型車両では、例えば、エンジンから駆動輪までの動力伝達経路に、流体の力学的作用を利用したトルクコンバータが設けられていない。 The MT type saddle-mounted vehicle is a saddle-mounted vehicle having a manual multi-speed transmission. A saddle-type vehicle is a vehicle in which the driver sits across the saddle. Examples of the saddle-mounted vehicle include a moped type, an off-road type, and an on-road type motorcycle. Further, the saddle-mounted vehicle is not limited to the motorcycle, and may be, for example, a motorcycle, an ATV (All-Terrain Vehicle), or the like. The tricycle may have two front wheels and one rear wheel, or may have one front wheel and two rear wheels. The drive wheels of the saddle-mounted vehicle may be rear wheels or front wheels. Further, the drive wheels of the saddle-mounted vehicle may be both rear wheels and front wheels. Further, it is preferable that the saddle-mounted vehicle is configured to be able to turn in a lean posture. A saddle-mounted vehicle configured to be able to turn in a lean posture is configured to turn in a posture tilted toward the center of a curve. As a result, the saddle-mounted vehicle configured to be able to turn in a lean posture opposes the centrifugal force applied to the vehicle when turning. In a saddle-mounted vehicle that is configured to be able to turn in a lean posture, lightness is required, so responsiveness to acceleration operations is important. In the MT type saddle type vehicle, for example, a torque converter utilizing the mechanical action of the fluid is not provided in the power transmission path from the engine to the drive wheels.
　エンジンは、例えば、高負荷領域と低負荷領域とを有するエンジンである。エンジンは、例えば、４ストロークエンジンである。４ストロークエンジンは、４ストロークの間に、高負荷領域と低負荷領域とを有する。高負荷領域と低負荷領域とを有する４ストロークエンジンは、例えば、単気筒エンジンである。高負荷領域と低負荷領域とを有する４ストロークエンジンは、例えば、２気筒エンジン、不等間隔燃焼型３気筒エンジン、又は、不等間隔燃焼型４気筒エンジンである。高負荷領域と低負荷領域とを有する４ストロークエンジンは、１サイクル７２０度の間に１８０度以上の連続不燃焼区間を含む。高負荷領域と低負荷領域とを有する４ストロークエンジンは、例えば、気筒数が３以上の等間隔燃焼型エンジンは含まない。４ストロークエンジンは、例えば、３つより少ない気筒を有するエンジンである。本開示の一実施形態において、４ストロークエンジンは、例えば、単気筒エンジン又は２気筒エンジンである。２気筒エンジンは、２つの気筒を有する不等間隔燃焼エンジンであってもよい。２つの気筒を有する不等間隔燃焼エンジンとして、例えばＶ型エンジンが挙げられる。
　高負荷領域と低負荷領域とを有する４ストロークエンジンでは、低い回転速度における回転の変動が、他のタイプのエンジンと比べ大きい。高負荷領域とは、エンジンの１燃焼サイクルのうち、負荷トルクが１燃焼サイクルにおける負荷トルクの平均値よりも高い領域をいう。低負荷領域とは、１燃焼サイクルにおける高負荷領域以外の領域をいう。クランク軸の回転角度を基準として見ると、エンジンでの低負荷領域は、例えば、高負荷領域より広い。圧縮行程は、高負荷領域と重なりを有する。但し、エンジンは、例えば、高負荷領域と低負荷領域とを有していなくてもよい。エンジンは、例えば、気筒数が３以上の等間隔燃焼型エンジンでもよい。 The engine is, for example, an engine having a high load region and a low load region. The engine is, for example, a 4-stroke engine. The four-stroke engine has a high load region and a low load region during the four strokes. The 4-stroke engine having a high load region and a low load region is, for example, a single cylinder engine. The 4-stroke engine having a high load region and a low load region is, for example, a 2-cylinder engine, an unequal-interval combustion type 3-cylinder engine, or an unequal-interval combustion type 4-cylinder engine. A four-stroke engine having a high load region and a low load region includes a continuous non-combustion section of 180 degrees or more during one cycle of 720 degrees. The 4-stroke engine having a high load region and a low load region does not include, for example, an evenly spaced combustion type engine having 3 or more cylinders. A four-stroke engine is, for example, an engine having less than three cylinders. In one embodiment of the present disclosure, the 4-stroke engine is, for example, a single-cylinder engine or a two-cylinder engine. The two-cylinder engine may be a non-equidistant combustion engine having two cylinders. As an unequal-spaced combustion engine having two cylinders, for example, a V-type engine can be mentioned.
In a 4-stroke engine having a high load region and a low load region, the fluctuation of rotation at a low rotation speed is larger than that of other types of engines. The high load region is a region in which the load torque is higher than the average value of the load torque in one combustion cycle in one combustion cycle of the engine. The low load region refers to a region other than the high load region in one combustion cycle. Looking at the rotation angle of the crank shaft as a reference, the low load region in the engine is wider than, for example, the high load region. The compression stroke has an overlap with the high load region. However, the engine may not have, for example, a high load region and a low load region. The engine may be, for example, an evenly spaced combustion type engine having 3 or more cylinders.
　始動発電機は、例えば永久磁石式の始動発電機である。始動発電機は、例えば永久磁石を使用しない始動発電機であってもよい。永久磁石式の始動発電機は、例えば、ブラシレスモータである。ブラシレスモータは、整流子を有さないモータである。始動発電機はエンジンを始動する始動モータとして機能する。また、始動発電機は、エンジンによって駆動され発電するモータジェネレータである。永久磁石式の始動発電機は、例えば、ブラシ付き直流モータでもよい。また、始動発電機は、例えばロータに永久磁石を有さないタイプでもよい。 The starting generator is, for example, a permanent magnet type starting generator. The starting generator may be, for example, a starting generator that does not use a permanent magnet. The permanent magnet type starting generator is, for example, a brushless motor. A brushless motor is a motor that does not have a commutator. The start generator functions as a start motor to start the engine. The starting generator is a motor generator that is driven by an engine to generate electricity. The permanent magnet type starting generator may be, for example, a brushed DC motor. Further, the starting generator may be, for example, a type in which the rotor does not have a permanent magnet.
　始動発電機は、例えばクランク軸と直結される。但し、始動発電機は、これに限られず、クランク軸と連動するように設けられていればよい。始動発電機は、例えば、クランク軸と常時連動する。始動発電機は、例えば、クラッチを介することなくクランク軸と接続されていればよい。例えば、始動発電機は、クランク軸とギア又はベルトを介して接続されていてもよい。 The starting generator is directly connected to, for example, the crank shaft. However, the starting generator is not limited to this, and may be provided so as to be interlocked with the crank shaft. The starting generator is, for example, always interlocked with the crank shaft. The starting generator may be connected to the crank shaft, for example, without the intervention of a clutch. For example, the starting generator may be connected to the crank shaft via gears or belts.
　クラッチは、クラッチレバーに対する運転者による操作に応じて作動するように構成されている。クラッチは、車両の発進時及び変速段の変更の両方の場面で、接続又は切断の状態が変化するように動作する発進・変速用クラッチである。クラッチとしては、湿式又は乾式の多板又は単板のクラッチが挙げられる。一実施形態において、クラッチは、湿式多板クラッチである。但し、遠心クラッチは、本発明におけるクラッチに該当しない。
　クラッチの状態は、例えば、クラッチレバーの位置として検出される。クラッチの状態は、例えば、クラッチの部材の位置として検出されてもよい。クラッチレバーの位置は、例えばクラッチレバー位置センサによって検出される。このようなクラッチレバー位置センサは、例えば、クラッチレバーの操作位置又は非操作位置を検出するスイッチで構成される。但し、クラッチレバー位置センサは、これに限られず、例えば、クラッチレバーの操作位置をアナログレベルで表す信号を出力するセンサで構成されてもよい。また、クラッチの状態は、例えば、クラッチの部品の位置、又は、クラッチレバーからクラッチに作動力を伝達する部材の位置として検出されてもよい。 The clutch is configured to operate in response to a driver's operation of the clutch lever. The clutch is a start / shift clutch that operates so as to change the state of connection or disconnection both when the vehicle starts and when the shift stage is changed. Examples of the clutch include a wet or dry multi-plate or single-plate clutch. In one embodiment, the clutch is a wet multi-plate clutch. However, the centrifugal clutch does not correspond to the clutch in the present invention.
The state of the clutch is detected, for example, as the position of the clutch lever. The state of the clutch may be detected, for example, as the position of a member of the clutch. The position of the clutch lever is detected by, for example, a clutch lever position sensor. Such a clutch lever position sensor is composed of, for example, a switch that detects an operated position or a non-operated position of the clutch lever. However, the clutch lever position sensor is not limited to this, and may be composed of, for example, a sensor that outputs a signal indicating the operation position of the clutch lever at an analog level. Further, the state of the clutch may be detected as, for example, the position of a component of the clutch or the position of a member that transmits an operating force from the clutch lever to the clutch.
　動力伝達経路は、エンジンのクランク軸から駆動輪までの、エンジンの動力を伝える経路における機械的な要素の総称である。動力伝達経路は、駆動軸、非駆動軸、駆動ギア、被駆動ギア、チェーンスプロケット、チェーン、駆動ベルトの少なくとも何れかを含む。 Power transmission path is a general term for mechanical elements in the path that transmits engine power from the crank shaft of the engine to the drive wheels. The power transmission path includes at least one of a drive shaft, a non-drive shaft, a drive gear, a driven gear, a chain sprocket, a chain, and a drive belt.
　多段変速装置は、運転者の操作により、変速比を変更する。多段変速装置は、シフトペダルの操作に応じて変速比を多段階に変更するように構成されている。多段変速装置は、ニュートラル状態を含む複数のギア段を有する。つまり、多段変速装置は、ニュートラル状態を含む多段階に変速比を変更することができる。多段変速装置は、例えば、ニュートラル状態と非ニュートラル状態とを有する。非ニュートラル状態は、４段以上の段階を含む。非ニュートラル状態は、例えば１速から４速までの変速段を含む。ニュートラル状態は、入力軸から出力軸に動力が伝達されない状態である。多段変速装置は、非ニュートラル状態時に、入力軸から入力された回転動力を、シフトペダルの操作に応じた変速比に変更して、出力軸に伝達する。無段変速機は、多段変速装置に該当しない。多段変速装置は、少なくとも１速以外の変速段を飛び越して遷移しないシーケンシャルタイプの多段変速装置である。
　多段変速装置のギア段は、例えば、多段変速装置に設けられたギアポジションセンサによって検出される。ギアポジションセンサは、多段変速装置のニュートラルを含む現在のギア段を検出して、制御装置に信号として送信する。 The multi-speed transmission changes the gear ratio by the operation of the driver. The multi-speed transmission is configured to change the gear ratio in multiple stages according to the operation of the shift pedal. The multi-speed transmission has a plurality of gear stages including a neutral state. That is, the multi-speed transmission can change the gear ratio in multiple stages including the neutral state. The multi-speed transmission has, for example, a neutral state and a non-neutral state. The non-neutral state includes four or more stages. The non-neutral state includes, for example, gears from 1st gear to 4th gear. The neutral state is a state in which power is not transmitted from the input shaft to the output shaft. In the non-neutral state, the multi-speed transmission changes the rotational power input from the input shaft to a gear ratio according to the operation of the shift pedal and transmits it to the output shaft. A continuously variable transmission does not fall under the category of a multi-speed transmission. The multi-speed transmission is a sequential type multi-speed transmission that does not jump over at least one speed other than the first speed and does not make a transition.
The gear stage of the multi-stage transmission is detected by, for example, a gear position sensor provided in the multi-stage transmission. The gear position sensor detects the current gear stage including the neutral of the multi-speed transmission and transmits it as a signal to the control device.
　制御装置は、エンジンの燃焼動作を制御する。また、制御装置は、例えば、始動発電機の駆動及び発電動作を制御する。制御装置は、例えば複数の装置が互いに離れた位置に構成されてもよく、また、一体に構成されていてもよい。制御装置は、プログラムを実行するプロセッサを有していてもよく、また、電子回路でもよい。 The control device controls the combustion operation of the engine. Further, the control device controls, for example, the drive of the starting generator and the power generation operation. In the control device, for example, a plurality of devices may be configured at positions separated from each other, or may be configured integrally. The control device may have a processor that executes a program, or may be an electronic circuit.
　アイドリングストップ機能は、所定のアイドリングストップ条件を満たすことによりエンジンを停止する機能である。所定のアイドリングストップ条件として、エンジンキーをＯＦＦにすること以外の条件が設定される。 The idling stop function is a function to stop the engine by satisfying a predetermined idling stop condition. As a predetermined idling stop condition, a condition other than turning off the engine key is set.
　ＭＴ型鞍乗型車両の走行中の状態は、ＭＴ型鞍乗型車両が停止していない状態又は実質的に停止していない状態のことである。ＭＴ型鞍乗型車両が停止している状態は、ＭＴ型鞍乗型車両の速度が０の状態である。ＭＴ型鞍乗型車両が実質的に停止している状態は、ＭＴ型鞍乗型車両の速度が０に近い状態である。ＭＴ型鞍乗型車両が停止している状態又は実質的に停止している状態は、例えば、車速センサによる速度の検出がされにくい状態である。車速センサにより速度が検出されない状態は、検出精度を考慮すると、例えば、ＭＴ型鞍乗型車両の速度が５ｋｍ／ｈ以下の状態である。即ち、ＭＴ型鞍乗型車両の走行中とは、ＭＴ型鞍乗型車両の速度が５ｋｍ／ｈよりも速い速度で走行している状態である。 The running state of the MT type saddle-type vehicle is a state in which the MT-type saddle-type vehicle is not stopped or is substantially not stopped. When the MT type saddle-mounted vehicle is stopped, the speed of the MT-type saddle-mounted vehicle is 0. The state in which the MT-type saddle-mounted vehicle is substantially stopped is a state in which the speed of the MT-type saddle-mounted vehicle is close to zero. The state in which the MT-type saddle-mounted vehicle is stopped or substantially stopped is, for example, a state in which it is difficult for the vehicle speed sensor to detect the speed. The state in which the speed is not detected by the vehicle speed sensor is, for example, a state in which the speed of the MT type saddle-mounted vehicle is 5 km / h or less in consideration of the detection accuracy. That is, the traveling of the MT type saddle-mounted vehicle is a state in which the speed of the MT-type saddle-mounted vehicle is traveling at a speed higher than 5 km / h.
　スロットル弁における実質的な最小開度とは、例えばスロットル弁に許容される最小の開度である。全閉可能なスロットル弁では、実質的な最小開度は０である。例えばアイドリング動作のため許容される最小開度が０でない場合、実質的な最小開度は、アイドリング動作のための開度である。スロットル弁における実質的な最小開度は、実質的には、例えば、アクセルグリップに運転者の操作力が加えられない場合の状態である。アクセルグリップは、運転者の操作に応じてスロットル弁の開閉を駆動する。 The substantially minimum opening of the throttle valve is, for example, the minimum opening allowed for the throttle valve. For a fully closed throttle valve, the practical minimum opening is zero. For example, when the minimum opening allowed for idling operation is not 0, the substantially minimum opening is the opening for idling operation. The substantially minimum opening degree of the throttle valve is substantially, for example, a state in which the driver's operating force is not applied to the accelerator grip. The accelerator grip drives the opening and closing of the throttle valve according to the operation of the driver.
　エンジン停止スイッチは、運転者がアイドリングストップを行う際に操作するスイッチである。運転者のエンジン停止スイッチの操作は、ＭＴ型鞍乗型車両のアイドリングストップ開始条件の一つである。この点において、操作すると必ずエンジンが停止するキルスイッチとは異なる。エンジン停止スイッチの操作は、運転者によるアイドリングストップを行う意思の表示である。 The engine stop switch is a switch that the driver operates when idling stop. The operation of the engine stop switch of the driver is one of the conditions for starting the idling stop of the MT type saddle type vehicle. In this respect, it differs from the kill switch, which always stops the engine when operated. The operation of the engine stop switch is an indication of the driver's intention to stop idling.
　「１速アイドリング速度」は、アイドリング時におけるエンジンの回転速度及び多段変速装置における１速の変速比に対応するＭＴ型鞍乗型車両の速度である。但し、「１速アイドリング速度」は、これに限られず、例えば、アイドリング時におけるエンジンの回転速度及び多段変速装置における１速の変速比に対応するＭＴ型鞍乗型車両の速度、又は１速での実際の走行速度のいずれか遅い方であってもよい。
　１速での実際の走行速度は、例えば、クラッチが接続されアクセルグリップにおける開度が０である場合に、ＭＴ型鞍乗型車両の速度が定常状態となった場合の走行速度である。１速での実際の走行速度は、ＭＴ型鞍乗型車両が停止状態から発進後の加速状態の速度ではない。
　「３速アイドリング速度」は、アイドリング時におけるエンジンの回転速度及び多段変速装置における３速の変速比に対応するＭＴ型鞍乗型車両の速度である。但し、「３速アイドリング速度」は、これに限られず、例えば、アイドリング時におけるエンジンの回転速度及び多段変速装置における３速の変速比に対応するＭＴ型鞍乗型車両の速度、又は３速での実際の走行速度のいずれか速い方であってもよい。
　３速での実際の走行速度は、例えば、クラッチが接続されアクセルグリップにおける開度が０である場合に、ＭＴ型鞍乗型車両の速度が定常状態となった場合の走行速度である。
　エンジンのアイドリングとは、例えばクラッチを切断している場合のようにエンジンからの動力が駆動輪に伝達されていない状態で、アクセルグリップにおける開度が０である場合のエンジンの動作である。アイドリング時におけるエンジンの回転速度とは、アイドリング時におけるエンジンのクランク軸の回転速度である。なお、暖機運転時と非暖機運転時とでアイドリング時の回転速度が異なる車両において、「アイドリング時におけるエンジンの回転速度」とは、非暖機運転時における回転速度をいう。
　変速比は、エンジンの回転速度とＭＴ型鞍乗型車両の速度との比を表す。変速比は、多段変速装置の各変速段（１速、２速、…）に対応して設定される。但し、変速比は、エンジンの回転速度とＭＴ型鞍乗型車両の速度との比そのものでなくともよく、例えば上記比に対し定数を乗じた値でもよい。例えば、変速比は、多段変速装置の入力軸の回転速度と出力軸の回転速度の比でもよい。この場合、多段変速装置の比に対し定数を乗じることで、エンジンの回転速度に対するＭＴ型鞍乗型車両の走行の速度が得られる。例えば、「アイドリング時におけるエンジンの回転速度及び多段変速装置における３速の変速比に対応するＭＴ型鞍乗型車両の速度」とは、例えば、上述したアイドリング時の回転速度に、変速段毎に設定された比及び定数を乗じた値である。 The "1st speed idling speed" is the speed of the MT type saddle-mounted vehicle corresponding to the rotation speed of the engine at the time of idling and the speed ratio of the 1st speed in the multi-speed transmission. However, the "1st speed idling speed" is not limited to this, and is, for example, the speed of the MT type saddle-type vehicle corresponding to the rotation speed of the engine at the time of idling and the speed ratio of the 1st speed in the multi-stage transmission, or the 1st speed. It may be the slower of the actual running speeds of.
The actual traveling speed in the first speed is, for example, the traveling speed when the speed of the MT type saddle-mounted vehicle becomes a steady state when the clutch is connected and the opening degree in the accelerator grip is 0. The actual running speed in the first speed is not the speed of the MT type saddle-type vehicle in the accelerated state after starting from the stopped state.
The "three-speed idling speed" is the speed of the MT-type saddle-mounted vehicle corresponding to the rotation speed of the engine during idling and the speed ratio of the three-speed in the multi-speed transmission. However, the "3-speed idling speed" is not limited to this, and is, for example, the speed of an MT-type saddle-mounted vehicle corresponding to the rotation speed of the engine during idling and the speed ratio of the 3-speed in the multi-stage transmission, or the 3-speed. It may be the faster of the actual running speeds of.
The actual traveling speed in the third speed is, for example, the traveling speed when the speed of the MT type saddle-mounted vehicle becomes a steady state when the clutch is connected and the opening degree in the accelerator grip is 0.
The idling of the engine is an operation of the engine when the opening degree in the accelerator grip is 0 in a state where the power from the engine is not transmitted to the drive wheels, for example, when the clutch is disengaged. The rotation speed of the engine at the time of idling is the rotation speed of the crank shaft of the engine at the time of idling. In a vehicle in which the rotation speed during idling differs between warm-up operation and non-warm operation, the "engine rotation speed during idling" means the rotation speed during non-warm operation.
The gear ratio represents the ratio between the rotation speed of the engine and the speed of the MT type saddle-type vehicle. The gear ratio is set corresponding to each gear (1st, 2nd, ...) Of the multi-speed gearbox. However, the gear ratio does not have to be the ratio itself between the rotation speed of the engine and the speed of the MT type saddle-mounted vehicle, and may be, for example, a value obtained by multiplying the above ratio by a constant. For example, the gear ratio may be the ratio of the rotation speed of the input shaft of the multi-stage transmission to the rotation speed of the output shaft. In this case, by multiplying the ratio of the multi-speed transmission by a constant, the traveling speed of the MT type saddle-mounted vehicle with respect to the rotation speed of the engine can be obtained. For example, "the speed of the MT type saddle-mounted vehicle corresponding to the rotation speed of the engine during idling and the speed ratio of the third speed in the multi-stage transmission" is, for example, the above-mentioned rotation speed during idling for each shift stage. It is a value multiplied by the set ratio and constant.
　基準速度範囲は、例えば、１速アイドリング速度から３速アイドリング速度までの区間に相当する範囲である。ただし、基準速度範囲は、特に限られず、１速アイドリング速度から３速アイドリング速度までの区間に相当する範囲よりも狭い範囲でもよい。
　アイドリング時におけるエンジンの回転速度及び多段変速装置における１速の変速比に対応するＭＴ型鞍乗型車両の速度は、ＭＴ型鞍乗型車両の種類に応じて異なる。アイドリング時におけるエンジンの回転速度及び多段変速装置における１速の変速比に対応する速度は、例えば、５ｋｍ／ｈよりも大きい速度である。また、アクセルグリップにおける開度が０である場合１速での実際の走行速度は、例えば、５ｋｍ／ｈよりも大きい速度である。例えば、ＭＴ型鞍乗型車両に一般的に備えられる速度検出器は、停止状態と極低速状態を区別することが容易でない。５ｋｍ／ｈ以下の速度は、ＭＴ型鞍乗型車両における走行中の速度に該当しない。
　アイドリング時におけるエンジンの回転速度及び多段変速装置における３速の変速比に対応するＭＴ型鞍乗型車両の速度は、ＭＴ型鞍乗型車両の種類に応じて異なる。アイドリング時におけるエンジンの回転速度及び多段変速装置における３速の変速比に対応する速度は、例えば、１８ｋｍ／ｈよりも小さい速度である。 The reference speed range is, for example, a range corresponding to a section from the 1st speed idling speed to the 3rd speed idling speed. However, the reference speed range is not particularly limited, and may be narrower than the range corresponding to the section from the 1st speed idling speed to the 3rd speed idling speed.
The speed of the MT type saddle-type vehicle corresponding to the rotation speed of the engine at idling and the speed ratio of the first speed in the multi-speed transmission device differs depending on the type of the MT-type saddle-type vehicle. The speed corresponding to the rotation speed of the engine at idling and the speed ratio of the first speed in the multi-stage transmission is, for example, a speed larger than 5 km / h. Further, when the opening degree in the accelerator grip is 0, the actual traveling speed in the first speed is, for example, a speed higher than 5 km / h. For example, a speed detector generally provided in an MT type saddle-mounted vehicle is not easy to distinguish between a stopped state and an extremely low speed state. Speeds of 5 km / h or less do not correspond to running speeds in MT-type saddle-mounted vehicles.
The speed of the MT type saddle-type vehicle corresponding to the rotation speed of the engine at idling and the speed ratio of the third speed in the multi-speed transmission device differs depending on the type of the MT type saddle-type vehicle. The speed corresponding to the rotation speed of the engine at idling and the speed ratio of the third speed in the multi-stage transmission is, for example, a speed smaller than 18 km / h.
　ＭＴ型鞍乗型車両が基準速度範囲の速度で走行中であることは、エンジンの燃焼動作停止の条件の一つである。ＭＴ型鞍乗型車両が基準速度範囲の速度で走行中、及び基準速度範囲を超える速度で走行中の双方で燃焼動作を停止できる形態は、本発明におけるＭＴ型鞍乗型車両に含まれる。即ち、条件（ａ）に関して、基準速度範囲と異なる速度範囲が設定されている車両であっても、当該速度範囲が、基準速度範囲を少なくとも部分的に含んでいる場合、当該ＭＴ型鞍乗型車両は、本発明のＭＴ型鞍乗型車両に該当する。例えば、設定された当該速度範囲が、１５～６０ｋｍ／ｈであり、基準速度範囲が、５～１８ｋｍ／ｈである場合、当該速度範囲は、基準速度範囲を部分的に含んでいるので、当該ＭＴ型鞍乗型車両は、本発明のＭＴ型鞍乗型車両に該当する。速度の条件について、ＭＴ型鞍乗型車両が基準速度範囲の速度で走行中の場合のみに燃焼動作を停止できる形態もまた、本発明におけるＭＴ型鞍乗型車両に含まれる。また、エンジンの燃焼動作を停止する条件として、条件（ａ）～（ｃ）に加え、他の条件が設定されているＭＴ型鞍乗型車両も、本発明のＭＴ型鞍乗型車両に該当する。即ち、条件（ａ）～（ｃ）に加え、他の条件も成立した場合に、エンジンの燃焼動作を停止してもよい。条件（ｄ）は、当該他の条件の一例である。当該他の条件は、この例に限定されない。 It is one of the conditions for stopping the combustion operation of the engine that the MT type saddle type vehicle is running at a speed within the reference speed range. The mode in which the MT type saddle-type vehicle can stop the combustion operation both while traveling at a speed in the reference speed range and while traveling at a speed exceeding the reference speed range is included in the MT-type saddle-type vehicle in the present invention. That is, even if the vehicle has a speed range different from the reference speed range with respect to the condition (a), if the speed range includes at least a part of the reference speed range, the MT type saddle type The vehicle corresponds to the MT type saddle-mounted vehicle of the present invention. For example, when the set speed range is 15 to 60 km / h and the reference speed range is 5 to 18 km / h, the speed range partially includes the reference speed range. The MT type saddle-mounted vehicle corresponds to the MT-type saddle-mounted vehicle of the present invention. Regarding the speed condition, the mode in which the combustion operation can be stopped only when the MT type saddle-type vehicle is traveling at a speed in the reference speed range is also included in the MT-type saddle-type vehicle in the present invention. Further, the MT type saddle-mounted vehicle in which other conditions are set in addition to the conditions (a) to (c) as the condition for stopping the combustion operation of the engine also corresponds to the MT-type saddle-mounted vehicle of the present invention. do. That is, the combustion operation of the engine may be stopped when other conditions are satisfied in addition to the conditions (a) to (c). The condition (d) is an example of the other conditions. The other conditions are not limited to this example.

FIG. 1 is a diagram showing a configuration of an MT type saddle-mounted vehicle 1 according to the first embodiment of the present invention. Here, FIG. 1A is a side view showing the configuration of the MT type saddle-mounted vehicle 1 in a simplified manner. FIG. 1B is a flowchart showing the operation of the control device 41 of the MT type saddle-mounted vehicle 1.
In the present specification and drawings, F indicates the front in the MT type saddle-mounted vehicle 1. B indicates the rear of the MT type saddle-mounted vehicle 1. FB indicates the front-rear direction in the MT type saddle-mounted vehicle 1. U indicates the upper side in the MT type saddle riding type vehicle 1. D indicates the lower part in the MT type saddle-mounted vehicle 1. UD indicates the vertical direction in the MT type saddle-mounted vehicle 1.
As shown in FIG. 1A, the MT type saddle-mounted vehicle 1 controls an engine 10, a drive wheel 15, a multi-stage transmission 30, a clutch lever 36, a clutch 35, and a starting generator 20. A device 41 is provided.
The engine 10 has a crank shaft 11. The engine 10 outputs the power generated by combustion via the rotating crank shaft 11.
The drive wheels 15 receive the power output from the engine 10 to drive the MT-type saddle-mounted vehicle 1.
The multi-speed transmission changes the gear ratio between the engine 10 and the drive wheels 15 to multiple stages including the neutral state according to the operation of the driver. The multi-speed transmission 30 is a sequential type multi-speed transmission.
The clutch 35 is provided on the power transmission path between the engine 10 and the multi-speed transmission 30. The clutch 35 interrupts and interrupts power transmission (power transmission path 25) between the engine 10 and the multi-speed transmission 30 in response to an operation on the clutch lever 36 by the driver.
The clutch lever 36 is operated by the driver to operate the clutch 35.
The starting generator 20 is connected to the crank shaft 11 so that power is transmitted to and from the crank shaft 11 without passing through the clutch 35. The start generator 20 starts the engine 10 by driving the crank shaft 11 when the engine 10 is started, and is driven by the crank shaft 11 to generate electricity during the combustion operation of the engine 10. The starting generator 20 is controlled by the control device 41 via the driver 21.
The control device 41 controls the operation of the engine 10 and also controls the operation of the start generator 20. More specifically, the control device 41 controls the operation of the engine 10 by controlling the amount and ignition of the air-fuel mixture supplied to the engine 10.
　図１（ｂ）に示すように、ＭＴ型鞍乗型車両１の制御装置４１は、下記の（ａ）～（ｃ）の３つの要件（ステップＳ１０１～Ｓ１０３）を全て満たした時に、エンジン１０の燃焼動作の停止を行う（ステップＳ１０４）。（ａ）～（ｃ）の要件は、
（ａ）ＭＴ型鞍乗型車両１が、基準速度範囲内の速度で走行中であること（ステップＳ１０１）、
（ｂ）多段変速装置３０がニュートラル状態であること（ステップＳ１０２）、及び、
（ｃ）運転者のクラッチレバー３６への操作に応じて、クラッチ３５が動力伝達経路を接続すること（ステップＳ１０３）、
である。ここで、（ａ）の基準速度範囲は、１速アイドリング速度から３速アイドリング速度までの区間の少なくとも一部に相当するように設定される。 As shown in FIG. 1 (b), the control device 41 of the MT type saddle-mounted vehicle 1 satisfies the following three requirements (steps S101 to S103) of (a) to (c) when the engine 10 is satisfied. (Step S104). The requirements of (a) to (c) are
(A) The MT type saddle-mounted vehicle 1 is traveling at a speed within the reference speed range (step S101).
(B) The multi-speed transmission 30 is in the neutral state (step S102), and
(C) The clutch 35 connects the power transmission path in response to the driver's operation on the clutch lever 36 (step S103).
Is. Here, the reference speed range of (a) is set so as to correspond to at least a part of the section from the 1st speed idling speed to the 3rd speed idling speed.
　ＭＴ型鞍乗型車両１の運転者が多段変速装置３０をニュートラル状態にし、且つクラッチ３５を接続する操作を行った場合、運転者がＭＴ型鞍乗型車両１を停止させる予定である場合が多い。即ち、多段変速装置３０がニュートラル状態の場合、クラッチ３５が接続されてもエンジン１０からの動力は駆動輪１５に伝達されない。運転者は、ＭＴ型鞍乗型車両１の走行中に多段変速装置３０をニュートラル状態に変更し且つクラッチ３５を接続する操作を実施する場合が多い。この操作を条件の一つとして、エンジン１０の燃焼動作を停止する。これによって、ＭＴ型鞍乗型車両１が走行している場合であって運転者がＭＴ型鞍乗型車両１を停止させる予定の場合にエンジン１０の燃焼動作を停止することができる。 When the driver of the MT-type saddle-mounted vehicle 1 puts the multi-speed transmission 30 in the neutral state and performs an operation of connecting the clutch 35, the driver may plan to stop the MT-type saddle-mounted vehicle 1. many. That is, when the multi-speed transmission 30 is in the neutral state, the power from the engine 10 is not transmitted to the drive wheels 15 even if the clutch 35 is engaged. In many cases, the driver changes the multi-speed transmission 30 to the neutral state and engages the clutch 35 while the MT type saddle-mounted vehicle 1 is traveling. With this operation as one of the conditions, the combustion operation of the engine 10 is stopped. As a result, the combustion operation of the engine 10 can be stopped when the MT type saddle-mounted vehicle 1 is traveling and the driver plans to stop the MT-type saddle-mounted vehicle 1.
　本実施形態のＭＴ型鞍乗型車両１における基準速度範囲は、１速アイドリング速度から３速アイドリング速度までの区間の少なくとも一部に相当するように設定される。ＭＴ型鞍乗型車両１は、基準速度範囲で走行している場合に、エンジン１０の燃焼動作が停止する。
　燃焼動作を停止した後、ＭＴ型鞍乗型車両１の走行が停止する前に再びＭＴ型鞍乗型車両１を加速したい場合に、運転者は、エンジン１０を再始動するとともに多段変速装置３０の状態をニュートラル状態から１速から３速の間の何れかの変速段に遷移させる。基準速度範囲内で走行している場合、多段変速装置３０の状態を１速から３速の間の何れかの変速段に遷移させることによって、ＭＴ型鞍乗型車両１の加速を開始可能な状態にすることができる。多段変速装置３０のニュートラル状態を１速から３速の間の何れかの変速段に遷移させる操作は、例えば、４速又は５速に操作する操作に掛かる時間よりも短い。従って、再びＭＴ型鞍乗型車両１を加速したい場合に、短時間で加速可能な状態にすることができる。 The reference speed range in the MT type saddle-mounted vehicle 1 of the present embodiment is set so as to correspond to at least a part of the section from the 1st speed idling speed to the 3rd speed idling speed. When the MT type saddle-mounted vehicle 1 is traveling in the reference speed range, the combustion operation of the engine 10 is stopped.
When the driver wants to accelerate the MT-type saddle-mounted vehicle 1 again after the combustion operation is stopped and before the MT-type saddle-mounted vehicle 1 stops running, the driver restarts the engine 10 and the multi-stage transmission 30. The state of is changed from the neutral state to any shift stage between the 1st speed and the 3rd speed. When traveling within the reference speed range, acceleration of the MT type saddle-mounted vehicle 1 can be started by shifting the state of the multi-speed transmission device 30 to any shift stage between the first speed and the third speed. Can be in a state. The operation of transitioning the neutral state of the multi-speed transmission 30 to any of the gears between the first speed and the third speed is shorter than the time required for the operation of operating the multi-speed gearbox 30 to, for example, the fourth speed or the fifth speed. Therefore, when it is desired to accelerate the MT type saddle-mounted vehicle 1 again, the acceleration can be achieved in a short time.
　従って、エンジン１０の停止後に再始動した場合における加速応答性の低下を抑制しつつ、走行中でも停止予定の操作に基づいてエンジン１０の燃焼を停止することができる。これにより、ＭＴ型鞍乗型車両１のアイドリングストップ機能の利便性を高めることができる。 Therefore, it is possible to stop the combustion of the engine 10 based on the operation scheduled to be stopped even during traveling, while suppressing the deterioration of the acceleration response when the engine 10 is restarted after the stop. As a result, the convenience of the idling stop function of the MT type saddle-mounted vehicle 1 can be enhanced.
　［第２実施形態］

A second embodiment of the present invention will be described. FIG. 2 is a diagram showing a configuration of an MT type saddle-mounted vehicle 2 according to a second embodiment of the present invention. Here, FIG. 2A is a side view showing the configuration of the MT type saddle-mounted vehicle 2 in a simplified manner. FIG. 2B is a flowchart showing the operation of the control device 42 of the MT type saddle-mounted vehicle 2. In this embodiment, the control device 42 is configured to perform the operation shown in FIG. In the present embodiment, the same configurations as those in the first embodiment are designated by the same reference numerals as those of the MT type saddle-mounted vehicle 1 shown in FIG.
　本実施形態のＭＴ型鞍乗型車両２のエンジン１０は、スロットル弁１２を有する。ＭＴ型鞍乗型車両２のエンジン１０は、スロットル弁１２の開度に応じて供給される混合気の燃焼により生じる動力を、回転するクランク軸１１を介して出力する。
　制御装置４２は、第１実施形態で説明した（ａ）から（ｃ）の条件（ステップＳ２０１～Ｓ２０３）に加え、更に下記（ｄ）の条件（ステップＳ２０４）を満たした場合に、エンジン１０の燃焼動作を停止する（ステップＳ２０５）。ここで、（ｄ）の条件は、
（ｄ）スロットル弁１２が実質的に最小開度の状態である。 The engine 10 of the MT type saddle-mounted vehicle 2 of the present embodiment has a throttle valve 12. The engine 10 of the MT type saddle-mounted vehicle 2 outputs the power generated by the combustion of the air-fuel mixture supplied according to the opening degree of the throttle valve 12 via the rotating crank shaft 11.
In addition to the conditions (steps S201 to S203) of (a) to (c) described in the first embodiment, the control device 42 further satisfies the following condition (d) (step S204) of the engine 10. The combustion operation is stopped (step S205). Here, the condition of (d) is
(D) The throttle valve 12 is in a state of substantially the minimum opening.
　本実施形態のＭＴ型鞍乗型車両２では、第１実施形態で説明した（ａ）から（ｃ）の条件に加え、更に（ｄ）スロットル弁１２が実質的に最小開度の状態である場合に、エンジン１０の燃焼動作が停止する。（ａ）から（ｄ）の条件が充足する場合、運転者がＭＴ型鞍乗型車両２を停止させる予定である可能性が更に高い。スロットル弁１２が実質的に最小開度であることも条件に含まれることにより、燃焼動作の停止が車両の停止に関連して実施される可能性がより高い。つまり、ＭＴ型鞍乗型車両２の運転者がＭＴ型鞍乗型車両２の停止を行う可能性が高い場合に、エンジン１０の燃焼動作の停止を行うことができる。従って、アイドリングストップを行うＭＴ型鞍乗型車両２において、運転者にとっての利便性をより高めることができる。 In the MT type saddle-mounted vehicle 2 of the present embodiment, in addition to the conditions (a) to (c) described in the first embodiment, (d) the throttle valve 12 is in a state of substantially the minimum opening. In this case, the combustion operation of the engine 10 is stopped. If the conditions (a) to (d) are satisfied, it is more likely that the driver plans to stop the MT-type saddle-mounted vehicle 2. Since the condition also includes that the throttle valve 12 has a substantially minimum opening, it is more likely that the stop of the combustion operation will be carried out in connection with the stop of the vehicle. That is, when the driver of the MT-type saddle-mounted vehicle 2 is likely to stop the MT-type saddle-mounted vehicle 2, the combustion operation of the engine 10 can be stopped. Therefore, in the MT type saddle-mounted vehicle 2 that performs idling stop, the convenience for the driver can be further enhanced.
　［第３実施形態］
　本発明の第３実施形態について説明する。図３は、本発明の第３実施形態に係るＭＴ型鞍乗型車両３の構成を示す図である。ここで、図３（ａ）は、ＭＴ型鞍乗型車両３の構成を簡略化して示す側面図である。図３（ｂ）は、ＭＴ型鞍乗型車両３の制御装置４３の動作を示すフローチャートである。本実施形態では、制御装置４３が、図２に示す動作を実施するように構成される。本実施形態において第１実施形態と同一の構成には、図１に示すＭＴ型鞍乗型車両１と同じ符号を付する。また、本実施形態は第２実施形態と組み合わせてもよい。 [Third Embodiment]
A third embodiment of the present invention will be described. FIG. 3 is a diagram showing a configuration of an MT type saddle-mounted vehicle 3 according to a third embodiment of the present invention. Here, FIG. 3A is a side view showing the configuration of the MT type saddle-mounted vehicle 3 in a simplified manner. FIG. 3B is a flowchart showing the operation of the control device 43 of the MT type saddle-mounted vehicle 3. In this embodiment, the control device 43 is configured to perform the operation shown in FIG. In the present embodiment, the same configurations as those in the first embodiment are designated by the same reference numerals as those of the MT type saddle-mounted vehicle 1 shown in FIG. Moreover, this embodiment may be combined with the second embodiment.
　本実施形態のＭＴ型鞍乗型車両３の制御装置４３は、運転者の操作により、クラッチ３５が、動力伝達経路２５を接続してから感応基準時間Ｔが経過した場合に、エンジン１０の燃焼動作を停止する。感応基準時間Ｔは、ゼロよりも大きい時間である。感応基準時間Ｔは、例えば予め設定された時間である。但し、感応基準時間Ｔは、ＭＴ型鞍乗型車両３の各部の状態又は車速に応じて設定されてもよい。 The control device 43 of the MT type saddle-mounted vehicle 3 of the present embodiment burns the engine 10 when the sensitivity reference time T has elapsed since the clutch 35 connected the power transmission path 25 by the driver's operation. Stop operation. The sensitive reference time T is a time larger than zero. The sensitive reference time T is, for example, a preset time. However, the sensitivity reference time T may be set according to the state or vehicle speed of each part of the MT type saddle-mounted vehicle 3.
　ＭＴ型鞍乗型車両３の運転者は、例えば停止する予定がない時に、多段変速装置３０をニュートラルの状態とし、一時的にクラッチ３５を接続の状態にする場合がある。ＭＴ型鞍乗型車両３の制御装置４３は、クラッチ３５が動力伝達経路２５を接続してから感応基準時間Ｔが経過した場合に、エンジン１０の燃焼動作を停止する。ＭＴ型鞍乗型車両３では、クラッチ３５によって動力伝達経路が一旦切断されても、感応基準時間Ｔが経過する前に、エンジン１０の燃焼動作を継続したまま動力伝達経路の切断状態に戻ることができる。これにより、ＭＴ型鞍乗型車両３では、クラッチ３５を接続状態にする操作の後、感応基準時間Ｔの経過前に、上記クラッチ３５についての操作を戻す操作を行なえば、燃焼動作の停止を阻止できる。このため、エンジン１０の再始動の操作を省略できる。従って、ＭＴ型鞍乗型車両３では、アイドリングストップを行うＭＴ型鞍乗型車両３において、利便性をより高めることができる。 The driver of the MT type saddle-mounted vehicle 3 may put the multi-speed transmission 30 in the neutral state and temporarily connect the clutch 35, for example, when there is no plan to stop. The control device 43 of the MT-type saddle-mounted vehicle 3 stops the combustion operation of the engine 10 when the sensitivity reference time T has elapsed since the clutch 35 connected the power transmission path 25. In the MT type saddle-mounted vehicle 3, even if the power transmission path is once disconnected by the clutch 35, the engine 10 returns to the disconnected state while continuing the combustion operation before the sensitive reference time T elapses. Can be done. As a result, in the MT type saddle-mounted vehicle 3, if the operation of returning the operation of the clutch 35 is performed after the operation of connecting the clutch 35 and before the lapse of the sensitivity reference time T, the combustion operation is stopped. It can be stopped. Therefore, the operation of restarting the engine 10 can be omitted. Therefore, in the MT type saddle-mounted vehicle 3, the convenience of the MT-type saddle-mounted vehicle 3 that performs idling stop can be further enhanced.
