The invention provides a hybrid power system and an engine starting method thereof, and a hybrid power vehicle. In a single-motor hybrid power system, on one hand, a clutch is arranged between an engine and an input shaft of a transmission; on the other hand, the motor is selectively in transmission connection with the input shaft and an output shaft of the transmission through the other two clutches instead of the clutch. Therefore, the motor of the hybrid power system can be selectively in transmission connection with the input shaft or the output shaft as required so that driving performance of the vehicle under different conditions is ensured; and meanwhile, the hybrid power system does not need to be additionally provided with the input shaft or another motor so that cost of the wholehybrid power system is considered.
本发明提供了一种混合动力系统及其发动机启动方法、混合动力车辆。在该单电机混合动力系统中,一方面,在发动机与变速器的输入轴之间设置一个离合器;另一方面,电机不经由上述离合器,而是经由另外两个离合器与变速器的输入轴和输出轴选择性地传动联接。这样,该混合动力系统的电机能够根据需要择一地与输入轴或输出轴传动联接,从而保证了不同情况下车辆的行驶性能;同时,该混合动力系统还不用额外设置输入轴或另一个电机,因而兼顾了整个混合动力系统的成本。
