The invention provides an oil-electricity separation type hybrid power system for a heavy-duty commercial vehicle, which comprises a first power unit and a second power unit, the first power unit adopts an internal combustion engine for power driving, the second power unit adopts a motor for power driving, and the first power unit is connected with a first drive axle; the second power unit is used for providing power for the first drive axle and is connected with the second drive axle; and the first power unit and the second power unit are used for providing power for the second drive axle and can cooperatively work according to different working conditions. The problems that in the prior art, a pure electric power assembly cannot adapt to complex working conditions, and a series-parallel hybrid power scheme is not ideal in energy conservation and emission reduction effect are effectively solved.

    本发明提供了一种重型商用车用油电分离式混合动力系统,包括:第一动力单元和第二动力单元,所述第一动力单元采用内燃机进行动力驱动,所述第二动力单元采用电动机进行动力驱动,所述第一动力单元与第一驱动桥连接;用于给第一驱动桥提供动力,所述第二动力单元与第二驱动桥连接;用于给第二驱动桥提供动力,所述第一动力单元和第二动力单元能够根据不同工况进行协同工作。本发明有效的解决了在现有技术中纯电动动力总成不能适应复杂工况,串并联混动方案节能减排效果不理想的问题。
