The invention discloses a hybrid power system and a working method, a torque distribution method and a gear shifting control method thereof. A transmission (AMT) of the hybrid power system adopts two independent input shafts (S1 and S2) and two electric machines (EM1 and EM2) which are in transmission connection with the two input shafts (S1 and S2) respectively, and an engine (ICE) is in transmission connection with one (EM1) of the two electric machines (EM1 and EM2) through a clutch (K0). Thus, on one hand, torque compensation can be always carried out in the gear shifting process of the hybrid power system, and therefore the torque interruption phenomenon of the hybrid power system in the gear shifting process is avoided; on the other hand, the hybrid power system can achieve a serial mode in which the engine (ICE) drives one motor (EM1) to charge the battery and the other motor (EM2) transmits torque to the transmission (AMT) for driving.
一种混合动力系统及其工作方法、扭矩分配方法和换挡控制方法。该混合动力系统的变速器(AMT)采用两个独立的输入轴(S1,S2)以及分别与两个输入轴(S1,S2)传动联接的两个电机(EM1,EM2),并且发动机(ICE)经由离合器(K0)与两个电机(EM1,EM2)中的一个电机(EM1)传动联接。这样,一方面,在该混合动力系统进行换挡的过程中总是能够进行扭矩补偿,从而避免了混合动力系统在换挡过程中的扭矩中断现象;另一方面,该混合动力系统能够实现发动机(ICE)驱动一个电机(EM1)对电池进行充电而另一个电机(EM2)向变速器(AMT)传递扭矩以用于驱动的串行模式。
