Description

本発明は、電車等において電動機で開閉が行われる車両ドアの開閉駆動を制御するドア制御装置に関する。   The present invention relates to a door control device that controls opening and closing driving of a vehicle door that is opened and closed by an electric motor in a train or the like.

鉄道車両用等のドア制御装置においては、車両の走行中にドアが開き乗客が車外に転落等しないようにする安全の確保が必要である。このため鉄道乗務員の操作スイッチによるドアの開動作指令が無い場合に、ノイズ等により開動作指令をドア制御装置が誤検知してドアの開動作を行わないようにする機能が必要である。
このため、特許文献１及び２においては、側扉動作指令を、多重化構成の入力装置に取り込んで多重化し、この多重化された側扉動作信号が一致した場合に側扉の開動作を行うようにしている。 In a door control device for a railway vehicle or the like, it is necessary to ensure safety so that the door is opened while the vehicle is running and passengers do not fall outside the vehicle. For this reason, when there is no door opening operation command by the operation switch of the train crew, a function is required to prevent the door control device from erroneously detecting the opening operation command due to noise or the like so as not to open the door.
For this reason, in Patent Documents 1 and 2, side door operation commands are taken in and multiplexed in an input device having a multiplexed configuration, and the side door opening operation is performed when the multiplexed side door operation signals match. I am doing so.

また、このような多重化構成の入力回路にノイズが混入することによって多重化された内のある側扉動作信号がノイズの影響で変化した場合、他の側扉動作信号と一致しなくなるので、この不一致条件で側扉を開動作させないようにして乗客の安全を確保している。
特開平９‐３０１１６１号公報 特開２００１−３０１６１６号公報 In addition, when a side door operation signal that has been multiplexed due to the mixing of noise into the input circuit of such a multiplexed configuration has changed due to the influence of noise, it will not match the other side door operation signal, The passenger's safety is ensured by not opening the side door under the mismatch condition.
Japanese Patent Laid-Open No. 9-301161 JP 2001-301616 A

しかし、特許文献１及び２のような従来技術においては、多重化構成の入力装置で多重化される前の側扉動作指令にノイズが混入することにより本来多重化後に一致しないはずの各信号が一致し、これによって本来側扉を開動作してはならないタイミングで側扉が開動作してしまい安全性が損なわれるという問題がある。
また、一過性のノイズ等の悪影響が解除された場合に、その悪影響で本来多重化後に一致するはずの各信号が不一致状態のままであれば、側扉の開閉動作が出来なくなるので、本来側扉を開閉動作しなければならないタイミングで開閉動作できなくなるという問題がある。
本発明は、このような課題に鑑みてなされたものであり、ドア動作指令信号がノイズ等の悪影響によって不適正に変化した場合でもドアが開かないように安全性を確保することができ、悪影響が解除された場合は適正にドアの開閉動作が行えるようにするドア制御装置を提供することを目的としている。 However, in the conventional techniques such as Patent Documents 1 and 2, each signal that should originally not be matched after multiplexing due to noise mixed in the side door operation command before being multiplexed by the input device having the multiplexed configuration is generated. Accordingly, there is a problem that the side door is opened at a timing when the side door should not be opened originally, and safety is impaired.
In addition, when the adverse effects such as transient noise are canceled, the side doors cannot be opened and closed if the signals that should be consistent after multiplexing are not matched due to the adverse effects. There is a problem that the side door cannot be opened and closed at the timing when the side door must be opened and closed.
The present invention has been made in view of such problems, and even when the door operation command signal changes improperly due to adverse effects such as noise, safety can be ensured so that the door does not open, An object of the present invention is to provide a door control device that can properly open and close the door when the is released.

上記目的を達成するために、本発明の請求項１によるドア制御装置は、入力される少なくとも２つのドア動作指令信号に応じて車両用のドアの開動作及び閉動作を制御するドア制御装置において、前記２つのドア動作指令信号のうち一方のドア動作指令信号がドアの開動作を要求する信号状態に変化してから設定時間内に他方のドア動作指令信号が開動作を要求する信号状態に変化しない場合は開動作指令の異常と判断し、この判断後、前記他方のドア動作指令信号が開動作を要求する信号状態に変化した場合でもドアの開動作を行わないように制御する制御手段を備えたことを特徴とする。
この構成によれば、ドア動作指令信号がノイズ等の悪影響によって不適正に変化した場合でもドアが開かないように安全性を確保することができる。 In order to achieve the above object, a door control device according to claim 1 of the present invention is a door control device that controls opening and closing operations of a vehicle door in accordance with at least two input door operation command signals. The door operation command signal of one of the two door operation command signals changes to a signal state requesting an opening operation of the door, and the other door operation command signal changes to a signal state requesting an opening operation within a set time. If it does not change, it is determined that the opening operation command is abnormal, and after this determination, control means for controlling the door opening operation not to be performed even when the other door operation command signal changes to a signal state that requires the opening operation. It is provided with.
According to this configuration, safety can be ensured so that the door does not open even when the door operation command signal changes inappropriately due to adverse effects such as noise.

また、本発明の請求項２によるドア制御装置は、請求項１において、前記制御手段は、前記開動作指令の異常を判断後に、全てのドア動作指令信号が閉動作を要求する信号状態に変化した場合に、当該異常が解消したと判断し、この判断後、一方のドア動作指令信号が開動作を要求する信号状態に変化してから前記設定時間内に他方のドア動作指令信号も開動作を要求する信号状態に変化した場合はドアの開動作が行えるように制御することを特徴とする。
この構成によれば、一過性のドアの開閉スイッチやドア動作指令信号の入力回路の異常やノイズによる影響により開動作異常と判断しても、その後、異常になっていた要因が無くなったことを判断した後は、ドアの開閉動作を行うことができる。 The door control device according to claim 2 of the present invention is the door control device according to claim 1, wherein after the control means determines that the opening operation command is abnormal, all door operation command signals change to a signal state requesting a closing operation. In this case, it is determined that the abnormality has been resolved, and after this determination, the other door operation command signal also opens within the set time after one door operation command signal changes to a signal state requesting an opening operation. In this case, the door is opened so that the door can be opened.
According to this configuration, even if it is determined that the opening operation is abnormal due to a temporary door open / close switch or door operation command signal input circuit abnormality or noise, the cause of the abnormality has been eliminated. After determining, the door can be opened and closed.

以上説明したように本発明のドア制御装置によれば、ドア動作指令信号がノイズ等の悪影響によって不適正に変化した場合でもドアが開かないように安全性を確保することができ、悪影響が解除された場合は適正にドアの開閉動作が行えるようにするという効果がある。   As described above, according to the door control device of the present invention, safety can be ensured so that the door will not open even if the door operation command signal changes improperly due to adverse effects such as noise, and the adverse effects are eliminated. If it is done, the door can be opened and closed properly.

以下、本発明の実施の形態を、図面を参照して説明する。
図１は、本発明の実施の形態に係る車両用のドア制御装置の構成を示す図である。
図１に示すドア制御装置１は、車両用のドア２を開閉駆動する電動機３に接続されており、複数のドア動作指令信号１０−１，１０−２が入力される入力回路部４と、その入力された複数のドア動作指令信号１０−１，１０−２の指令がドア２の開動作であるか、閉動作であるかを判断し、この判断結果に基いてドア２の開又は閉動作制御信号を出力する開閉動作判断制御部（制御手段）５と、その開又は閉動作制御信号に応じて電動機３がドア２を開又は閉駆動するための電力を、その電動機３へ供給する電力変換部６とを備えて構成されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration of a vehicle door control device according to an embodiment of the present invention.
A door control device 1 shown in FIG. 1 is connected to an electric motor 3 that drives a door 2 for a vehicle to open and close, and an input circuit unit 4 to which a plurality of door operation command signals 10-1 and 10-2 are input, It is determined whether the inputted commands of the plurality of door operation command signals 10-1 and 10-2 are an opening operation or a closing operation of the door 2, and the opening or closing of the door 2 is based on the determination result. An open / close operation determination control unit (control means) 5 that outputs an operation control signal and electric power for the motor 3 to open or close the door 2 in response to the opening or closing operation control signal are supplied to the motor 3. The power conversion unit 6 is provided.

次に、上記のドア制御装置１を鉄道車両に用いた場合の構成図を図２に示し、その説明を行う。
この図２に示す鉄道車両７は、側面に複数のドア２が開閉自在に設けられ、各ドア２にドア制御装置１が電気的に接続されている。各ドア制御装置１には運転台８に配設された開閉スイッチ８ａが配線接続されている。そして、各ドア２の開閉を行うために乗務員が開閉スイッチ８ａの操作を行う。この操作に応じてドア２の開閉動作を行うための複数のドア指令がドア制御装置１に伝えられる。ここでは、便宜的に複数のドア２の動作指令が、第１の開動作指令信号１２−１と第２の開動作指令信号１２−２から構成されているとする。 Next, a configuration diagram when the door control device 1 is used in a railway vehicle is shown in FIG. 2 and will be described.
In the railway vehicle 7 shown in FIG. 2, a plurality of doors 2 are provided on a side surface so as to be openable and closable, and the door control device 1 is electrically connected to each door 2. Each door control device 1 is wired to an open / close switch 8 a disposed in the cab 8. Then, in order to open and close each door 2, the crew operates the open / close switch 8a. In response to this operation, a plurality of door commands for opening and closing the door 2 are transmitted to the door control device 1. Here, for convenience, it is assumed that the operation commands for the plurality of doors 2 are composed of a first opening operation command signal 12-1 and a second opening operation command signal 12-2.

但し、図３に示すように、ドア制御装置１の開閉動作判断制御部５は、後述の動作にて説明する第１の開動作指令監視タイマ５ａと、第２の開動作指令監視タイマ５ｂと、タイマ制御部５ｃと、開指令異常フラグ５ｄと、開動作フラグ５ｅと、フラグ制御部５ｆとを備えて構成されているとする。
このような構成のドア制御装置１によるドア２の開閉動作を、図４に示すフローチャートを参照して説明する。 However, as shown in FIG. 3, the opening / closing operation determination control unit 5 of the door control device 1 includes a first opening operation command monitoring timer 5a, a second opening operation command monitoring timer 5b, which will be described later. The timer control unit 5c, the opening command abnormality flag 5d, the opening operation flag 5e, and the flag control unit 5f are assumed to be configured.
The opening / closing operation | movement of the door 2 by the door control apparatus 1 of such a structure is demonstrated with reference to the flowchart shown in FIG.

ステップＳ１において、第１の開動作指令信号１２−１及び第２の開動作指令信号１２−２の双方又は何れかがドア制御装置１の入力回路部４に入力される。
ステップＳ２において、開閉動作判断制御部５にて第１及び第２の開動作指令信号１２−１，１２−２の双方の信号が入力されたか否か、言い換えればＯＮ（オン）となったか否かが判断される。双方ともＯＮの場合は、ステップＳ３において、タイマ制御部５ｃの制御によって第１及び第２の開動作指令監視タイマ５ａ，５ｂの双方がリセットされる。 In step S <b> 1, both or one of the first opening operation command signal 12-1 and the second opening operation command signal 12-2 is input to the input circuit unit 4 of the door control device 1.
In step S2, whether or not both of the first and second opening operation command signals 12-1 and 12-2 are input by the opening / closing operation determination control unit 5, in other words, whether or not it has been turned ON. Is judged. If both are ON, both the first and second opening operation command monitoring timers 5a and 5b are reset under the control of the timer control unit 5c in step S3.

そして、ステップＳ４において、フラグ制御部５ｆによって開指令異常フラグ５ｄがＯＦＦ（オフ）であるか否かが判断される。この結果、ＯＦＦの場合は、フラグ制御部５ｆによって開動作フラグ５ｅがセットされ、ステップＳ６において、開動作フラグ５ｅがセットされたか否かが判断される。
セットされていれば、ステップＳ７において、開閉動作判断制御部５から開動作制御信号が電力変換部６へ出力され、電力変換部６がドア２を開駆動するための電力を電動機３へ供給し、これによってドア２が開動作を行う。 In step S4, the flag controller 5f determines whether or not the open command abnormality flag 5d is OFF (off). As a result, in the case of OFF, the opening operation flag 5e is set by the flag control unit 5f, and in step S6, it is determined whether or not the opening operation flag 5e is set.
If it is set, in step S7, the opening / closing operation determination control unit 5 outputs an opening operation control signal to the power conversion unit 6, and the power conversion unit 6 supplies electric power for opening the door 2 to the motor 3. As a result, the door 2 opens.

上記ステップＳ４において、開指令異常フラグ５ｄがＯＦＦでない場合、つまりＯＮの場合は開動作指令が異常なので、ステップＳ６の判断を行う。この結果、開動作フラグ５ｅがセットされていなければ、ステップＳ８において、開閉動作判断制御部５から閉動作制御信号が電力変換部６へ出力され、電力変換部６がドア２を閉駆動するための電力を電動機３へ供給し、これによってドア２が閉動作を行う。   If the opening command abnormality flag 5d is not OFF in step S4, that is, if it is ON, the opening operation command is abnormal, and therefore the determination in step S6 is performed. As a result, if the opening operation flag 5e is not set, a closing operation control signal is output from the opening / closing operation determination control unit 5 to the power conversion unit 6 in step S8, and the power conversion unit 6 drives the door 2 to close. Is supplied to the electric motor 3, and the door 2 is thereby closed.

つまり、図５に示すように、第１の開動作指令信号１２−１が時刻Ｔ１でＯＮとなった後に、予め定められた設定時間Ｔｓ以内の時刻Ｔ２で第２の開動作指令信号１２−２がＯＮとなり、これによって双方ともオンした場合は、ドア２の開動作を行う。その後、第１の開動作指令信号１２−１が時刻Ｔ３にてＯＦＦとなった場合に閉動作を行うようになっている。   That is, as shown in FIG. 5, after the first opening operation command signal 12-1 is turned ON at time T1, the second opening operation command signal 12- at the time T2 within a predetermined set time Ts. When 2 is turned on and both of them are turned on, the door 2 is opened. After that, the closing operation is performed when the first opening operation command signal 12-1 is turned OFF at time T3.

次に、上記ステップＳ２において、第１及び第２の開動作指令信号１２−１，１２−２の双方がＯＮでない場合は、ステップＳ９において、開閉動作判断制御部５にて第１の開動作指令信号１２−１がＯＮで、第２の開動作指令信号１２−２がＯＦＦであるか否かが判断される。
この結果、図６に示すように、時刻Ｔ１で例えば運転台６の開閉スイッチ８ａの異常や入力回路部４の異常により第１の開動作指令信号１２−１がＯＮとなり、また第２の開動作指令信号１２−２はＯＦＦであった場合、ステップＳ１０において、第１の開動作指令監視タイマ５ａでは計時動作が継続され、第２の開動作指令監視タイマ５ｂはタイマ制御部５ｃによってリセットされる。 Next, in step S2, if both the first and second opening operation command signals 12-1 and 12-2 are not ON, the opening / closing operation determination control unit 5 performs the first opening operation in step S9. It is determined whether or not the command signal 12-1 is ON and the second opening operation command signal 12-2 is OFF.
As a result, as shown in FIG. 6, at time T1, the first opening operation command signal 12-1 is turned ON due to, for example, an abnormality in the opening / closing switch 8a of the cab 6 or an abnormality in the input circuit section 4, and the second opening operation is performed. When the operation command signal 12-2 is OFF, in step S10, the time measurement operation is continued in the first opening operation command monitoring timer 5a, and the second opening operation command monitoring timer 5b is reset by the timer control unit 5c. The

そして、ステップＳ１１において、タイマ制御部５ｃで第１の開動作指令監視タイマ５ａの計時時間が図６に示す設定時間Ｔｓを超えたか否かが判断される。この結果、設定時間Ｔｓを超えた場合、ステップＳ１２において、フラグ制御部５ｆによって開指令異常フラグ５ｄがセットされる。更にステップＳ１３において、開動作フラグ５ｅがリセットされ、ステップＳ６へ進む。この場合、ステップＳ６では開動作フラグ５ｅはセットされていないと判断されるので、ステップＳ８でドア２が閉状態を継続する。   In step S11, the timer controller 5c determines whether or not the time measured by the first opening operation command monitoring timer 5a has exceeded the set time Ts shown in FIG. As a result, when the set time Ts is exceeded, in step S12, the open command abnormality flag 5d is set by the flag control unit 5f. Further, in step S13, the opening operation flag 5e is reset, and the process proceeds to step S6. In this case, since it is determined that the opening operation flag 5e is not set in step S6, the door 2 continues to be closed in step S8.

つまり、第１の開動作指令信号１２−１のみがＯＮとなってから設定時間Ｔｓを超えた場合は、その後、図６の時刻Ｔ２で第２の開動作指令信号１２−２がオンとなっても、開指令異常フラグ５ｄがセットされているのでドア２は開動作を行わない。
次に、上記ステップＳ９の結果がＮＯの場合は、ステップＳ１４において、開閉動作判断制御部５にて第１の開動作指令信号１２−１がＯＦＦで、第２の開動作指令信号１２−２がＯＮであるか否かが判断される。 That is, when the set time Ts is exceeded after only the first opening operation command signal 12-1 is turned on, the second opening operation command signal 12-2 is turned on at time T2 in FIG. However, since the opening command abnormality flag 5d is set, the door 2 does not open.
Next, when the result of step S9 is NO, in step S14, the first opening operation command signal 12-1 is OFF in the opening / closing operation determination control unit 5, and the second opening operation command signal 12-2. Whether or not is ON is determined.

この結果、図７に示すように、時刻Ｔ１で例えば運転台６の開閉スイッチ８ａの異常や入力回路部４の異常により第２の開動作指令信号１２−２がＯＮとなり、また第１の開動作指令信号１２−１はＯＦＦであった場合、ステップＳ１５において、第１の開動作指令監視タイマ５ａはタイマ制御部５ｃによってリセットされ、第２の開動作指令監視タイマ５ｂでは計時動作が継続される。   As a result, as shown in FIG. 7, at time T1, the second opening operation command signal 12-2 is turned ON due to, for example, an abnormality in the opening / closing switch 8a of the cab 6 or an abnormality in the input circuit unit 4, and the first opening operation is performed. When the operation command signal 12-1 is OFF, in step S15, the first opening operation command monitoring timer 5a is reset by the timer control unit 5c, and the second opening operation command monitoring timer 5b continues the timing operation. The

そして、ステップＳ１６において、タイマ制御部５ｃで第２の開動作指令監視タイマ５ｂの計時時間が図７に示す設定時間Ｔｓを超えたか否かが判断される。この結果、設定時間Ｔｓを超えた場合、ステップＳ１７において、フラグ制御部５ｆによって開指令異常フラグ５ｄがセットされる。更にステップＳ１８において、開動作フラグ５ｅがリセットされ、ステップＳ６へ進む。この場合、ステップＳ６では開動作フラグ５ｅはセットされていないと判断されるので、ステップＳ８でドア２が閉状態を継続する。
つまり、第２の開動作指令信号１２−２のみがＯＮとなってから設定時間Ｔｓを超えた場合は、その後、図７の時刻Ｔ２で第１の開動作指令信号１２−１がオンとなっても、開指令異常フラグ５ｄがセットされているのでドア２は開動作を行わない。 In step S16, the timer controller 5c determines whether or not the time measured by the second opening operation command monitoring timer 5b has exceeded the set time Ts shown in FIG. As a result, when the set time Ts is exceeded, the open command abnormality flag 5d is set by the flag control unit 5f in step S17. Further, in step S18, the opening operation flag 5e is reset, and the process proceeds to step S6. In this case, since it is determined that the opening operation flag 5e is not set in step S6, the door 2 continues to be closed in step S8.
That is, when the set time Ts is exceeded after only the second opening operation command signal 12-2 is turned ON, then the first opening operation command signal 12-1 is turned ON at time T2 in FIG. However, since the opening command abnormality flag 5d is set, the door 2 does not open.

次に、上記ステップＳ１４の結果がＮＯの場合、例えば図７に示すように、時刻Ｔ３にて第１及び第２の開動作指令信号１２−１，１２−２の双方がＯＮからＯＦＦとなった場合、ステップＳ１９において、第１及び第２の開動作指令監視タイマ５ａ，５ｂの双方がリセットされ、ステップＳ２０において図７の時刻Ｔ３に示すように開指令異常フラグ５ｄがリセットされ、更にステップＳ２１において開動作フラグ５ｅがリセットされる。この場合、ステップＳ６で開動作フラグ５ｅはセットされていないと判断されるので、ステップＳ８においてドア２の閉状態のままとなる。   Next, when the result of step S14 is NO, as shown in FIG. 7, for example, both the first and second opening operation command signals 12-1 and 12-2 are turned from ON to OFF at time T3. In step S19, both the first and second opening operation command monitoring timers 5a and 5b are reset. In step S20, the opening command abnormality flag 5d is reset as shown at time T3 in FIG. In S21, the opening operation flag 5e is reset. In this case, since it is determined in step S6 that the opening operation flag 5e is not set, the door 2 remains closed in step S8.

その後、図７の時刻Ｔ４に示すように第１及び第２の開動作指令信号１２−１，１２−２の双方がＯＮになると、ステップＳ２の判断結果がＹｅｓとなるので、前述で説明したと同様にステップＳ３で第１及び第２の開動作指令監視タイマ５ａ，５ｂの双方がリセットされた後、ステップＳ４での判断は開指令異常フラグ５ｄがリセットされているのでＹｅｓとなる。そして、ステップＳ５において、開動作フラグ５ｅがセットされる。この場合、ステップＳ６では開動作フラグ５ｅがセットされていると判断されるので、ステップＳ７において、開閉動作判断制御部５から開動作制御信号が電力変換部６へ出力され、電力変換部６がドア２を開駆動するための電力を電動機３へ供給し、これによってドア２が開動作を行う。   After that, when both the first and second opening operation command signals 12-1 and 12-2 are turned on as shown at time T4 in FIG. 7, the determination result in Step S2 is Yes. Similarly, after both the first and second opening operation command monitoring timers 5a and 5b are reset in step S3, the determination in step S4 is Yes because the opening command abnormality flag 5d is reset. In step S5, the opening operation flag 5e is set. In this case, since it is determined in step S6 that the opening operation flag 5e is set, in step S7, an opening / closing operation determination control unit 5 outputs an opening operation control signal to the power conversion unit 6, and the power conversion unit 6 Electric power for opening the door 2 is supplied to the electric motor 3, whereby the door 2 opens.

つまり、図７の時刻Ｔ３にて第１及び第２の開動作指令信号１２−１，１２−２の双方ともＯＦＦしたことで、第１の開動作指令信号１２−１が早期にＯＮしたのは一過性の現象と判断し、開指令異常フラグ５ｄをリセットする。その後、時刻Ｔ４で第１及び第２の開動作指令信号１２−１，１２−２の双方ともＯＮし、開指令異常フラグ５ｄがセットしていない条件をもってドア２の開動作を行う。   That is, the first opening operation command signal 12-1 was turned on early because both the first and second opening operation command signals 12-1 and 12-2 were turned OFF at time T3 in FIG. Is determined to be a transient phenomenon, and the open command abnormality flag 5d is reset. Thereafter, both the first and second opening operation command signals 12-1 and 12-2 are turned ON at time T4, and the door 2 is opened under the condition that the opening command abnormality flag 5d is not set.

以上説明したように本実施の形態のドア制御装置１によれば、開閉動作判断制御部５によって、第１及び第２の開動作指令信号１２−１，１２−２のうち第１の開動作指令信号１２−１がドア２の開動作を要求する信号状態に変化してから設定時間Ｔｓ内に第２の開動作指令信号１２−２が開動作を要求する信号状態に変化しない場合は開動作指令の異常と判断し、この判断後、第２の開動作指令信号１２−２が開動作を要求する信号状態に変化した時でもドア２の開動作を行わないように制御するようにした。
これによって、第１及び第２の開動作指令信号１２−１，１２−２がノイズ等の悪影響によって不適正に変化した場合でもドア２が開かないように安全性を確保することができる。これによって、車両運行中に誤ってドア２が開き乗客が車外へ転落する等の事故を防止して安全性を確保することができる。 As described above, according to the door control device 1 of the present embodiment, the first opening operation of the first and second opening operation command signals 12-1 and 12-2 is performed by the opening / closing operation determination control unit 5. If the second opening operation command signal 12-2 does not change to the signal state requesting the opening operation within the set time Ts after the command signal 12-1 changes to the signal state requesting the opening operation of the door 2, it is opened It is determined that the operation command is abnormal, and after this determination, control is performed so that the door 2 does not open even when the second opening operation command signal 12-2 changes to a signal state that requires the opening operation. .
Accordingly, safety can be ensured so that the door 2 does not open even when the first and second opening operation command signals 12-1 and 12-2 are inappropriately changed due to adverse effects such as noise. As a result, it is possible to ensure safety by preventing accidents such as the door 2 being accidentally opened during vehicle operation and passengers falling outside the vehicle.

また、開閉動作判断制御部５によって、上記の開動作指令の異常を判断後に、第１及び第２の開動作指令信号１２−１，１２−２の双方が閉動作を要求する信号状態に変化した場合に、当該異常が解消したと判断し、この判断後、第１の開動作指令信号１２−１が開動作を要求する信号状態に変化してから設定時間Ｔｓ内に第２の開動作指令信号１２−２も開動作を要求する信号状態に変化した場合はドア２の開動作が行えるように制御するようにした。
これによって、一過性の開閉スイッチ８ａやドア動作指令信号の入力回路部４の異常やノイズによる影響により開動作異常と判断しても、その後、異常になっていた要因が無くなったことを判断した後は、ドア２の開閉動作を行うことができる。これによって、車両運行上の利便性を確保することができる。 After the opening / closing operation determination control unit 5 determines that the opening operation command is abnormal, both the first and second opening operation command signals 12-1 and 12-2 change to a signal state requesting the closing operation. In this case, it is determined that the abnormality has been resolved, and after this determination, the second opening operation is performed within the set time Ts after the first opening operation command signal 12-1 changes to the signal state requesting the opening operation. The command signal 12-2 is also controlled so that the opening operation of the door 2 can be performed when the signal state changes to a signal state that requires the opening operation.
As a result, even if it is determined that the opening operation is abnormal due to the abnormality of the temporary opening / closing switch 8a or the input circuit unit 4 of the door operation command signal or the influence of noise, it is determined that the cause of the abnormality has disappeared thereafter. After that, the door 2 can be opened and closed. Thereby, convenience in vehicle operation can be ensured.
