The invention provides a hybrid power driving system, a control method thereof, and a vehicle. The system comprises an engine, a differential assembly, 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, an inner input shaft, an outer input shaft, a plurality of shift gear pairs connected between the outer input shaft and the power output shaft in a coupling mode, a clutch connected with the engine and a synchronizer arranged on the power output shaft. The inner input shaft is connected with a driving disc of the clutch, the outer input shaft is connected with a driven disc of the clutch, the differential assembly is in coupling connection with the power outputshaft and the second motor, and the first motor is in coupling connection with the inner input shaft. The system structure is simplified, so the total length of a transmission is shortened; in addition, a dual-motor structure is introduced, so that the driving modes are more diversified, and the fuel economy of the vehicle is improved; and meanwhile, the two motors can drive and generate electricity, so the energy recovery efficiency is improved.

    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、差速器总成、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、内输入轴、外输入轴、耦合连接在外输入轴和动力输出轴之间的多组档位齿轮副、与发动机连接的离合器、以及设置在动力输出轴上的同步器,内输入轴与离合器的主动盘连接,外输入轴与离合器的从动盘连接,差速器总成分别与动力输出轴和第二电机耦合连接,第一电机与内输入轴耦合连接。本发明简化了系统结构,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,提高车辆燃油经济性,同时两个电机既能驱动又能发电,提高能量回收效率。
