The present invention relates to a hybrid power system, a hybrid electric vehicle and a method of controlling operation of a vehicle. The hybrid power system comprises an electric motor, an engine anda transmission mechanism, wherein the electric motor is used for connecting to a first driving wheel set of the vehicle to provide a first driving force to the vehicle; the engine is used for providing a second driving force for the vehicle; the transmission mechanism is used for transmitting the second driving force output by the engine to the second driving wheel set, the transmission mechanismincludes an input end, an output end and a synchronizer, the input end is used for being connected with the engine, and the output end is used for being connected with the second driving wheel set ofthe vehicle; the synchronizer is used for controlling on and off of power transmission between the output end of the transmission mechanism and the second driving wheel set so as to control on and off of power between the engine and the second driving wheel set. Power switching is achieved through the synchronizer, a high-price clutch is omitted, and manufacturing cost of the whole hybrid electric vehicle is saved.

    本发明涉及一种混合动力系统、混合动力汽车和控制车辆运行的方法,所述混合动力系统包括:电动机,用于与车辆的第一驱动轮组连接,以向车辆提供第一驱动力;发动机,用于向车辆提供第二驱动力;传动机构,用于将所述发动机输出的第二驱动力传递至所述第二驱动轮组,所述传动机构包括输入端、输出端和同步器,所述输入端用于与所述发动机连接,所述输出端用于与车辆的第二驱动轮组连接;所述同步器用以控制所述传动机构的所述输出端与所述第二驱动轮组间动力传递的通断,以此控制所述发动机与所述第二驱动轮组间动力的接通和断开。本发明的优点在于,采用同步器实现动力切换,省去价格高昂的离合器,节省混合动力汽车整车制造成本。
