The invention discloses a longitudinal series-parallel hybrid power transmission system and a control method. The longitudinal series-parallel hybrid power transmission system comprises an engine, a P1 motor, a P3 motor and a rear axle. The engine, the P1 motor and the P3 motor are coaxially arranged, and the engine and the P1 motor are connected through a speed increasing mechanism so that power can be transmitted between the engine and the P1 motor. The P3 motor is connected with the rear axle through a speed reducing mechanism so as to realize wheel driving; the P1 motor and the P3 motor are connected through a clutch so that connection or disconnection of the engine and the P3 motor can be achieved. The functions of pure electric drive, engine direct drive, series/parallel hybrid power transmission and the like are achieved, and the purposes of energy conservation and consumption reduction of the whole vehicle are achieved. The planet row structure is adopted to solve the problems of insufficient modular design, large radial arrangement space and the like of the system.

    本发明公开了一种纵置混联式混合动力传动系统及控制方法,包括发动机、P1电机、P3电机以及后桥;所述发动机与所述P1电机以及所述P3电机同轴设置,所述发动机与所述P1电机之间通过升速机构连接,以实现所述发动机与所述P1电机之间传递动力;所述P3电机与所述后桥之间通过减速机构连接,以实现车轮驱动;所述P1电机与所述P3电机之间通过离合器连接,以实现所述发动机与所述P3电机的连接或断开。本发明满足纯电驱动,发动机直驱,串联/并联混合动力传动等功能,满足整车节能降耗目标。采用行星排结构解决系统模块化设计不足,径向布置空间大等问题。
