The invention discloses a hybrid power system and a driving control method thereof and a hybrid electric vehicle, the hybrid power system comprises an engine, a generator, a driving motor, a differential mechanism and an output shaft, and the differential mechanism is in transmission connection with the output shaft; the engine is in transmission connection with the output shaft through the first clutch, the second clutch, the stepless speed change mechanism and the one-way communication part which are sequentially arranged, and the one-way communication part is arranged to limit power to be transmitted from the stepless speed change mechanism to the output shaft in a one-way mode. The engine is in transmission connection with the generator through a first transmission unit arranged between the first clutch and the second clutch; the driving motor is in transmission connection with the output shaft through the third transmission unit. According to the hybrid power system, multi-mode driving of the system can be achieved, and impact on the engine is small when the generator generates electricity.

    本发明公开了一种混合动力系统及其驱动控制方法和混合动力汽车,其中,混合动力系统包括发动机、发电机、驱动电机以及差速器和输出轴,差速器与输出轴传动相连,发动机通过依次布置的第一离合器、第二离合器、无极变速机构和单向连通部与输出轴传动相连,单向连通部被设置为限定动力由无极变速机构向输出轴单向传输;发动机通过配置于第一离合器和第二离合器之间的第一传动单元与发电机传动相连;驱动电机通过第三传动单元与输出轴传动相连。本发明的混合动力系统可实现系统多模式的驱动,且在发电机发电时对发动机的冲击较小。
