The invention provides a hybrid power driving system, a control method 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, a power input shaft connected with the engine, a plurality of gear shift gear pairs connected between the power input shaft and the power output shaft in a coupling mode, and a synchronizer arranged on the power output shaft. The first motor is in coupling connection with one gear shift gear pair, and the differential assembly is coupled with the second motor and the power output shaft. The system structure is simplified, so the total length of the transmission is shortened; in addition, a dual-motor structure is introduced, so that the driving mode matching is more diversified, the working mode of the system can be further refined, and the fuel economy of the vehicle is further 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、与发动机连接的动力输入轴、耦合连接在动力输入轴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,第一电机与其中一档位齿轮副耦合连接,差速器总成分别与第二电机和动力输出轴耦合。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,系统的工作模式可以进一步细化,从而进一步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。
