The invention provides a commercial vehicle power system and a control method thereof, relates to the field of power systems, and adopts the scheme that the commercial vehicle power system comprises a first drive axle and a second drive axle and further comprises a first drive unit and a second drive unit, the first drive unit is connected with the first drive axle through a first gearbox, and the second drive unit is connected with the second drive axle through a second gearbox; the second drive unit is connected with the second drive axle through a second gearbox, and the first drive axle and the second drive axle are not connected through a transmission shaft. The torque of the two drive axles is decoupled, torque distribution can be carried out according to the principle of axle loads of the drive axles and/or the total efficiency of a power source, the power consumption of the vehicle is reduced, the fuel economy of the whole vehicle is improved, the drive wheels are prevented from slipping, and the control performance of the whole vehicle is improved.

    本发明提供了一种商用车动力系统及其控制方法,涉及动力系统领域,采用的方案是:包括第一驱动桥和第二驱动桥,还包括第一驱动单元和第二驱动单元,所述第一驱动单元通过第一变速箱与所述第一驱动桥连接,所述第二驱动单元通过第二变速箱与所述第二驱动桥连接,所述第一驱动桥和所述第二驱动桥之间不存在传动轴连接。本发明的两个驱动桥扭矩解耦,能够根据驱动桥的轴荷和/或动力源总效率为原则进行扭矩分配,降低了车辆的电耗,提升了整车的燃油经济性,避免驱动轮打滑,提升整车操控性能。
