The invention discloses a single-clutch dual-motor multi-gear hybrid power driving system, which can realize the functions of pure electric driving, series driving, parallel driving, speed regulation and gear shifting and the like by only utilizing one clutch. Compared with a steam EDU GEN1 system, a clutch at the end of a driving TM motor is omitted, precise speed regulation and gear shifting of the TM motor are achieved through control, various mode functions of the hybrid power system are achieved, and meanwhile the cost of the power system is reduced. Compared with a public P2 system, series efficient charging and driving can be achieved, good drivability and economical efficiency are achieved at the low speed and the low electric quantity, an engine can be started through a single motor, and the drivability problem caused when the P2 system is started in a sliding friction mode is solved. Compared with a Ba Dii P3 system, the motor is arranged at the front end of the gearbox, gear shifting can be achieved through the gearbox, and better economical efficiency and dynamic property are achieved through pure electric driving. The invention further discloses a vehicle applying the system and a single-clutch dual-motor multi-gear hybrid power driving method.

    本发明公开了一种单离合器双电机多档混合动力驱动系统,仅利用一个离合器,可以实现纯电驱动、串联驱动、并联驱动、调速换挡等功能。相比上汽EDU GEN1系统,本发明取消了驱动TM电机端离合器,通过控制实现TM电机的精准调速换挡,既实现混动系统各种模式功能,同时降低动力系统成本。相比大众P2系统,本发明可以实现串联高效充电和驱动,在低速低电量拥有较好的驾驶性和经济性,也可利用单独电机启动发动机,避免的P2系统滑磨启动时的驾驶性问题。相比比亚迪P3系统,本发明电机布置在变速箱前端,可利用变速箱实现换挡,纯电行驶拥有更好的经济性和动力性。本发明还公开了一种应用上述系统的车辆和单离合器双电机多档混合动力驱动方法。
