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 motors. The transmission mechanism comprises a power output shaft, double clutches connected with the engine, a plurality of gear shift gear pairs coupled between the double clutches and the power output shaft, and a synchronizer arranged on the power output shaft. One gear shift gear pair is coupled with the first motor in a gear manner, and the other gear shift gear pair is coupled with the second motor in a gear manner through a second idle wheel assembly. The method comprises the following steps: state parameters of the vehicle are obtained; and according to the state parameters ofthe vehicle, the synchronizer and/or the double clutches are/is controlled to be combined or separated so as to control the system to enter a corresponding working 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, 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的同步器,其中一组档位齿轮副与第一电机齿轮耦合,另一组档位齿轮副通过第二惰轮总成与第二电机齿轮耦合,方法包括:获取车辆的状态参数;根据车辆的状态参数,控制同步器和/或双离合器结合或分离,以控制系统进入对应的工作模式。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。
