The invention provides a dual-motor power confluence hybrid power system, and belongs to the field of hybrid power vehicles. The engine and the first motor form a power confluence hybrid power system through the compound planetary gear mechanism, and the power confluence hybrid power system is connected with a small sun gear and a planet carrier of the compound planetary gear mechanism. The second motor forms a low-gear electric driving system and is in transmission connection with a large sun gear of the compound planetary gear mechanism. Therefore, when the vehicle comprising the power confluence hybrid power system is at a high speed, the vehicle can be driven through high-speed dual-power power confluence parallel hybrid driving of the first motor and the engine, when the vehicle is at the high speed, the engine and the first motor are in a parallel driving hybrid power state; therefore, compared with a high-speed single-mode input type power split hybrid power system in the prior art, the defects that the working efficiency and the fuel consumption performance of the whole power split hybrid power system are poor when the vehicle is at the high speed can be overcome.

    本发明提供双电机功率合流混合动力系统,属于混合动力车辆领域。其中发动机与电机一经由复合行星齿轮机构组成功率合流混合动力系统,分别联接复合行星机构的小太阳轮和行星架。而电机二组成低速档电动驱动系统,传动联接复合行星齿轮机构的大太阳轮。因此,当包括根据本发明的功率合流混合动力系统的车辆处于较高的速度时,可以通过电机一与发动机的高速双动力功率合流并联混合驱动,使得车辆处于较高的速度时,发动机与电机一处于并联驱动混合动力状态,这样与现有技术的高速时单模输入式功率分流混合动力系统相比,能够消除车辆高速时整个功率分流混合动力系统的工作效率和燃油消耗性差的缺陷。
