Description

하이브리드 차량의 파워트레인{Power Train for Hybrid Vehicle}Power Train for Hybrid Vehicle

본 발명은 하이브리드 차량의 파워트레인에 관한 것으로서, 보다 상세하게는 구동륜에 구동력을 제공하는 동력원으로서 내연기관인 엔진과, 전기에 의해 구동되는 모터제너레이터를 사용하는 하이브리드 차량의 파워트레인 구조에 관한 기술이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power train of a hybrid vehicle, and more particularly, to a power train structure of a hybrid vehicle using an engine that is an internal combustion engine as a power source for providing driving force to a drive wheel and a motor generator driven by electricity.

엔진과 모터제너레이터를 사용하는 하이브리드 차량은, 저속에서는 상대적으로 저속토크특성이 우수한 모터제너레이터로부터의 동력을 구동력으로 이용하도록 하고, 고속에서는 상대적으로 고속토크특성이 우수한 엔진으로부터의 동력으로 차량이 구동되도록 하는 개념을 기반으로 하여 차량의 연비를 개선하도록 하고 있다.A hybrid vehicle using an engine and a motor generator may use power from a motor generator having a relatively low torque characteristic as a driving force at a low speed, and a vehicle may be driven with power from an engine having a relatively high torque characteristic at a high speed. Based on the concept to improve the fuel economy of the vehicle.

또한, 하이브리드 차량은 모터제너레이터만으로 구동되는 동안에는 엔진에 의한 배기가스가 발생할 여지가 없어서, 연비 개선과 배기가스 저감의 장점을 가진 친환경적인 자동차 기술로 인정받고 있다.In addition, while the hybrid vehicle is driven only by the motor generator, there is no room for the exhaust gas generated by the engine, and thus, the hybrid vehicle is recognized as an environmentally friendly vehicle technology having the advantages of fuel efficiency improvement and exhaust gas reduction.

상기와 같은 하이브리드 차량의 동력전달장치에는 동력분기식 장치가 있는데, 상기 동력분기식 장치는 다시 단일모드방식과 2모드방식이 있으며, 상기 단일모드방식은 변속 제어를 위한 클러치나 브레이크 등과 같은 작동요소가 필요 없지만, 고속 주행시 효율이 저하되어 연비가 낮고 대형차량에 적용하기 위해서는 부가적인 토크 증배장치가 필요한 단점이 있다.The power transmission device of the hybrid vehicle as described above has a power divergence device, and the power divergence device again includes a single mode method and a two mode method, and the single mode method operates elements such as a clutch or a brake for shift control. Although there is no need, the efficiency is reduced at high speeds, the fuel economy is low, and in order to apply to large vehicles, there is a disadvantage that an additional torque multiplier is required.

한편, 상기 2모드방식은 고속 주행시의 효율확보는 물론, 그 구성에 따라 자체적으로 토크의 증배가 가능하도록 설계할 수 있어서 중대형 차량에도 적용이 가능한 이점이 있다.On the other hand, the two-mode method can be designed to increase the torque itself according to the configuration as well as to ensure the efficiency of high-speed driving, there is an advantage that can be applied to medium and large vehicles.

본 발명은 동력분기방식에 의한 다중모드의 구현은 물론, 일반 변속기의 변속단처럼 고정된 기어비를 복수 개 제공하여, 차량의 주행상황에 따라 이들 다양한 주행모드에 의한 다중모드 운행이 가능하도록 함으로써, 중/고속 주행시의 연비를 크게 향상시킬 수 있도록 한 하이브리드 차량의 파워트레인을 제공함에 그 목적이 있다.The present invention, as well as the implementation of the multi-mode by the power branch method, by providing a plurality of fixed gear ratio like the gear stage of the general transmission, by enabling the multi-mode operation by these various driving modes according to the driving situation of the vehicle, It is an object of the present invention to provide a power train of a hybrid vehicle that can significantly improve fuel efficiency during medium / high speed driving.

상기한 바와 같은 목적을 달성하기 위하여 안출된 본 발명 하이브리드 차량의 파워트레인은The powertrain of the hybrid vehicle of the present invention devised to achieve the object as described above

상기 제1브레이크(B1)는 상기 제2유성기어세트(PG2)의 제2선기어(S2)의 회전을 구속할 수 있도록 설치되고, 상기 엔진(Engine)은 상기 제1유성기어세트(PG1)의 제1캐리어(C1)에 연결되며, 상기 제1모터제너레이터(MB1)는 상기 제1유성기어세트(PG1)의 제1선기어(S1)에 연결되고, 상기 제2모터제너레이터(MG2)는 상기 제2유성기어세트(PG2)의 제2링기어(R2)에 연결된다.The first brake B1 is installed to restrain the rotation of the second sun gear S2 of the second planetary gear set PG2, and the engine is configured to control the rotation of the first planetary gear set PG1. The first motor generator MB1 is connected to the first sun gear S1 of the first planetary gear set PG1, and the second motor generator MG2 is connected to the first carrier C1. It is connected to the second ring gear R2 of the two planetary gear sets PG2.

여기서, 상기 동력원과 제1유성기어세트(PG1) 및 제2유성기어세트(PG2)는 각 회전축이 모두 동심축을 이루어 배치된다.Here, the power source, the first planetary gear set (PG1) and the second planetary gear set (PG2) are all arranged in a concentric axis of the rotation axis.

상기한 바와 같이 구성된 본 발명의 작용을 도면을 참조하여 살펴보면 다음과 같다. Looking at the operation of the present invention configured as described above with reference to the drawings.

도 2는 본 발명 실시예의 파워트레인이 구현할 수 있는 운전모드를 도표로 표시한 것으로서, 상기 제1브레이크(B1)와 제1클러치(CL1) 및 제2클러치(CL2)의 작동상태의 조합에 의해 다양한 운전모드를 구현할 수 있도록 되어 있다.2 is a diagram showing an operation mode that can be implemented by the powertrain of the embodiment of the present invention, and is formed by a combination of operating states of the first brake B1, the first clutch CL1, and the second clutch CL2. Various operation modes can be implemented.

도 3은 전기차모드인 EV모드를 도시한 것으로서, 엔진(Engine)은 정지해 있는 상태이고 제1브레이크(B1)만 체결되어 상기 제2유성기어세트(PG2)의 제2선기어(S2)를 고정하고 있다.3 illustrates an EV mode in an electric vehicle mode, in which an engine is stopped and only the first brake B1 is engaged to fix the second sun gear S2 of the second planetary gear set PG2. Doing.

따라서, 상기 제2모터제너레이터(MG2)가 상기 제2링기어(R2)를 구동하면 상기 제2캐리어(C2)에서는 감속되어 출력요소(OUT)로 동력이 인출되어 차량을 기동시키게 된다. Therefore, when the second motor generator MG2 drives the second ring gear R2, the second motor C2 is decelerated and power is drawn to the output element OUT to start the vehicle.

이때, 상기 엔진(Engine)은 정지한 상태이고, 상기 제2캐리어(C2)에 연결된 제1링기어(R1)는 회전되므로 상기 제1선기어(S1)에 연결된 제1모터제너레이터(MB1)는 상기 제2모터제너레이터(MG2)와는 반대방향으로 회전하는 상태가 된다.In this case, the engine is stopped and the first ring gear R1 connected to the second carrier C2 is rotated, so that the first motor generator MB1 connected to the first sun gear S1 is rotated. It rotates in the opposite direction to the 2nd motor generator MG2.

도 4는 EV모드에서 하이브리드모드인 HEV1모드로 전환하는 상태를 설명하고 있는 바, 상기 EV모드 상태에서 상기 제1모터제너레이터(MB1)의 회전 속도를 줄이면 엔진(Engine)의 속도가 상승하면서 엔진(Engine)에 시동이 걸리게 되어 HEV1모드가 된다.4 illustrates a state in which the EV mode is switched from the EV mode to the HEV1 mode. When the rotation speed of the first motor generator MB1 is reduced in the EV mode, the engine speed increases and the engine ( The engine is started and the mode is HEV1.

이 HEV1모드에서는 입력분기구조로 작용되며 주행 제어 상태에 따라 동력순환이 발생할 수 있으므로 이러한 주행상태에 들어가지 않도록 운전제어를 설정하여야 한다.In this HEV1 mode, it acts as an input branch structure and power circulation can occur according to the driving control state.

도 5는 HEV1모드에서 고정기어비모드인 FG1모드로 전환하는 상태를 도시하고 있는 바, 상기 HEV1모드에서 상기 제1모터제너레이터(MB1)의 속도가 0이 되도록 하고 상기 제2클러치(CL2)를 결합하면 FG1모드가 된다. 물론, 상기 제2클러치(CL2)가 결합할 때 상기 제2클러치(CL2)의 양단은 동일 속도로 회전하므로 상대마찰은 없는 상태이다.FIG. 5 shows a state of switching from the HEV1 mode to the FG1 mode, which is a fixed gear ratio mode. In the HEV1 mode, the speed of the first motor generator MB1 is zero and the second clutch CL2 is coupled. Enters the FG1 mode. Of course, when the second clutch CL2 is engaged, both ends of the second clutch CL2 rotate at the same speed, so that there is no relative friction.

상기 FG1모드의 고정기어비는 물론 유성기어세트의 잇수에 의해 결정되는 것으로서, 여기서 기어비는 제2링기어잇수/(제2링기어잇수+제1선기어(S1)잇수)가 된다.The fixed gear ratio of the FG1 mode is, of course, determined by the number of teeth of the planetary gear set, where the gear ratio is the number of second ring gears / (number of second ring gears + number of first sun gears S1).

도 6은 FG1모드에서 하이브리드모드인 HEV2모드로 전환하는 상태를 설명하고 있다. FG1모드에서 제1브레이크(B1)를 해제하면 HEV2모드가 되며, 이때에는 상기 엔진(Engine), 제1모터제너레이터(MB1), 제2모터제너레이터(MG2)의 구동상태에 따라 차량의 주행성능이 결정되며, 배터리의 충전상태에 따라 필요시에는 배터리를 충전할 수도 있다.6 illustrates a state of switching from the FG1 mode to the HEV2 mode, which is a hybrid mode. When the first brake B1 is released in the FG1 mode, the vehicle is in the HEV2 mode. In this case, the driving performance of the vehicle depends on the driving state of the engine, the first motor generator MB1, and the second motor generator MG2. The battery may be charged if necessary according to the state of charge of the battery.

이 HEV2모드는 FG2모드로 변환되기 전까지 유지되며, 시내 주행시 가장 많이 사용되는 구간이므로 효율적인 운전을 위한 최적제어가 필요한 구간이다.This HEV2 mode is maintained until it is converted to the FG2 mode and is the most used section when driving in the city.

상기 최적제어는 엔진(Engine)의 운전점을 연비가 가장 좋은 곳에서 작동하도록 상기 제1모터제너레이터(MB1)와 제2모터제너레이터(MG2)가 구동력을 출력 또는 발전하도록 하는 알고리즘을 사용한다.The optimal control uses an algorithm that causes the first motor generator MB1 and the second motor generator MG2 to output or generate a driving force so that the operating point of the engine operates at the place where the fuel economy is the best.

이 HEV2모드는 복합분기모드(Under drive)로 작동하며 동력순환이 발생하지 않는 변속비에서만 운전되도록 설정한다.This HEV2 mode operates in underdrive mode and is set to operate only at transmission ratios where no power cycle occurs.

도 7은 HEV2모드에서 또 다른 고정기어비모드인 FG2모드로 전환하는 상태를 설명한 것으로서, HEV2모드에서 제1유성기어세트(PG1)와 제2유성기어세트(PG2)의 모든 요소의 회전속도가 같아지게 되면 상기 제2클러치(CL2)를 결합하여 구현한다.FIG. 7 illustrates a state of switching from the HEV2 mode to the FG2 mode, which is another fixed gear ratio mode, in which the rotational speeds of all elements of the first planetary gear set PG1 and the second planetary gear set PG2 are the same. If it loses, it implements by combining the second clutch (CL2).

즉, 이 FG2모드는 상기 제1모터제너레이터(MB1)와 제2모터제너레이터(MG2) 및 제1유성기어세트(PG1)와 제2유성기어세트(PG2)를 포함한 모든 요소가 같은 속도로 회전하며, 엔진(Engine)으로부터 입력된 동력은 그대로 상기 출력요소(OUT)로 빠져 나가게 되어 1:1의 변속비를 구현하는 상태가 되는 것이다.That is, in this FG2 mode, all the elements including the first motor generator MB1 and the second motor generator MG2 and the first planetary gear set PG1 and the second planetary gear set PG2 rotate at the same speed. The power input from the engine is directly exited to the output element OUT, and thus the speed is 1: 1.

상기와 같은 상태에서 상기 제2클러치(CL2)가 해제되면 또 다른 하이브리드모드인 HEV3모드로 전환이 이루어진다.In the above state, when the second clutch CL2 is released, switching to another hybrid mode HEV3 mode is performed.

즉, 도 8에 도시된 바와 같이, 상기 FG2모드에서 상기 제2클러치(CL2)가 해제되어 이루어지며, HEV2와 동일하게 상기 엔진(Engine), 제1모터제너레이터(MB1), 제2모터제너레이터(MG2)의 구동상태에 따라 차량의 주행성능이 결정되는 것이다.That is, as shown in FIG. 8, the second clutch CL2 is released in the FG2 mode, and the engine, the first motor generator MB1, and the second motor generator ( The driving performance of the vehicle is determined according to the driving state of the MG2).

이 HEV3모드는 차량의 고속 주행시 사용되므로 효율적인 운전을 위하여 제1모터제너레이터(MB1)와 제2모터제너레이터(MG2)는 급가속이나 등판 등에서만 사용되고 배터리의 충전상태에 따라 필요시에는 배터리를 충전하도록 작동된다.Since the HEV3 mode is used for high speed driving of the vehicle, the first motor generator MB1 and the second motor generator MG2 are used only for rapid acceleration or climbing, so as to charge the battery when necessary according to the state of charge of the battery. It works.

물론, 이 모드에서도 엔진(Engine)의 운전점을 엔진(Engine)의 연비가 가장 좋은 곳에서 작동되도록 상기 제1모터제너레이터(MB1)와 제2모터제너레이터(MG2)가 구동력을 출력 또는 발전하도록 하는 알고리즘을 적용한다. Of course, in this mode, the first motor generator MB1 and the second motor generator MG2 output or generate a driving force so that the operating point of the engine is operated at the place where the fuel economy of the engine is the best. Apply the algorithm.

이 HEV3모드는 복합분기모드(OVER DRIVE)로 작동하며 동력순환이 발생하지 않는 변속비에서만 운전되도록 설정한다.This HEV3 mode operates in OVER DRIVE and is set to operate only at gear ratios without power cycle.
