The invention discloses a dual-motor hybrid power system, a control method and a vehicle, the dual-motor hybrid power system structurally comprises a driving motor, an engine, a power generator, a differential mechanism, a first connecting piece, a clutch set and a torsion limiting damper, and all the components are in transmission connection through nine gears and six connecting shafts; a plurality of transmission paths and a plurality of driving working modes are designed; according to the scheme, the engine, the generator and the driving motor can all participate in driving, the generator can be completely decoupled from the engine when participating in driving, rotating energy loss is reduced, the economical efficiency of the whole vehicle is improved, the system has multiple modes of using functions, the application range is wide, practicability is high, the limitation of the maximum rotating speed of the driving motor on the maximum vehicle speed is avoided, and the driving efficiency is improved. And the dynamic property of the whole vehicle is improved.

    本发明公开了一种双电机混合动力系统、控制方法及车辆,该系统在结构上包括驱动电机、发动机、发电机、差速器、第一连接件、离合器组以及限扭减振器,各个组件之间通过九个齿轮以及六个连接轴实现传动连接,设计了多条传动路径以及多种驱动工作模式;本方案中,发动机、发电机和驱动电机均可以参与驱动,发电机参与驱动时可与发动机完全解耦,减少了转动能量损失,提高了整车经济性,系统具有多个模式的使用功能,适用范围广,实用性强,避免了驱动电机最高转速对最高车速的限制,提高了整车动力性。
