The invention provides a hybrid power driving system, a control method 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, a power input shaft, a plurality of gear shift gear pairs connected between the power output shaft and the power input shaft in a coupling mode, and a first synchronizer arranged on the power output shaft and used for gear synchronization. A driving shaft of the first motor is in coupling connectionwith the power input shaft through a first gear pair, a driving shaft of the second motor is in coupling connection with the power output shaft through a connecting mechanism, and a second synchronizer used for gear shift synchronization is arranged on the connecting shaft. 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, and the total length of the transmission is shortened; and in addition, a dual-motor structure is introduced, so that the matching of driving modes is more 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、动力输入轴、耦合连接在动力输出轴和动力输入轴之间的多组档位齿轮副、以及设置在动力输出轴上用于档位同步的第一同步器,第一电机的驱动轴通过第一齿轮副与动力输入轴耦合连接,第二电机的驱动轴通过连接机构与动力输出轴耦合连接,连接轴上设有用于档位同步的第二同步器。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。
