The longitudinally-arranged dual-motor hybrid power system comprises an engine and a hybrid power gearbox, the hybrid power gearbox comprises a first motor, a second motor and a dual clutch connected with the engine, the dual clutch is arranged to be used for controlling combination and separation between the engine and the first motor and between the engine and the second motor, and the second motor is a generator. According to the longitudinally-arranged dual-motor hybrid power system, three modes of pure electric driving, range extending and engine direct driving can be achieved through coordinated control over all the components; when the generator does not work, the generator can be decoupled from the engine and does not need to be reversely dragged, and dragging loss is effectively reduced. The invention further discloses a control method of the longitudinally-arranged dual-motor hybrid power system and a vehicle.
本发明公开了一种纵置双电机混合动力系统,包括发动机和混动变速箱,混动变速箱包括第一电机、第二电机和与发动机连接的双离合器,双离合器设置成用于控制发动机与第一电机和第二电机之间的结合与分离,第二电机为发电机。本发明的纵置双电机混合动力系统,通过各部件的协调控制,可以实现纯电驱动、增程、发动机直驱三种模式;发电机不工作时,可与发动机解耦,无需被反拖,有效降低拖滞损失。本发明还公开了一种纵置双电机混合动力系统的控制方法和一种车辆。
