The invention provides a hybrid power driving system, a control method thereof, and a vehicle. The system comprises an engine, a first motor, a second motor, a transmission mechanism and a battery connected with the first motor and the second motor. The transmission mechanism comprises a power output shaft, double clutches connected with the engine, a plurality of shift gear pairs connected between the double clutches and the power output shaft in a coupling mode, and a synchronizer arranged on the power output shaft and used for achieving gear synchronization. A first motor gear is arranged on a motor shaft of the first motor, a second motor gear is arranged on a motor shaft of the second motor, one shift gear pair is connected with the first motor gear in a coupling mode, and the other shift gear pair is connected with the second motor gear in a coupling mode. State parameters of the vehicle are matched with the working mode of the system, the fuel economy of the vehicle is improved,the system structure is simplified, the total length of a transmission is shortened, and in addition, a dual-motor structure is introduced to make the matching of driving modes diversified.
本发明提供一种混合动力驱动系统、控制方法及车辆,系统包括发动机、第一电机、第二电机、传动机构以及与第一电机和第二电机连接的电池,传动机构包括动力输出轴、与发动机连接的双离合器、耦合连接在双离合器和动力输出轴之间的多组档位齿轮副、以及设置在动力输出轴上用于实现档位同步的同步器,第一电机的电机轴上设置有第一电机齿轮,第二电机的电机轴上设置有第二电机齿轮,其中一组档位齿轮副与第一电机齿轮耦合连接,另一组档位齿轮副与第二电机齿轮耦合连接。本发明实现车辆的状态参数与系统的工作模式相适配,提高车辆燃油经济性,简化系统结构,缩短变速器总长,此外还引入双电机结构,使驱动方式搭配更加多样化。
