The invention discloses a vehicle power assembly system, a control method thereof and a vehicle, and belongs to the technical field of vehicles. The system comprises a front axle power assembly and a rear axle power assembly, the rear axle power assembly comprises a rear axle driving motor, a single-gear speed reducer, clutches, a left rear half shaft, a right rear half shaft and a controller, and the clutches comprise a left clutch and a right clutch; after speed reduction and torque increase are carried out on rear driving force provided by the rear axle driving motor through the single-gear speed reducer, the rear driving force is transmitted to a left rear wheel of the vehicle through the left clutch and the left rear half shaft and transmitted to a right rear wheel of the vehicle through the right clutch and the right rear half shaft so as to drive the vehicle to run. According to the system, the clutch is arranged to replace an original differential mechanism with a differential lock, when the vehicle is in the limiting working condition, free distribution of driving force of the two rear wheels can be achieved by controlling the state of the clutch, the disengagement capacity of the vehicle is improved, and the vehicle has better safety and stability.
本发明公开了一种车辆动力总成系统及其控制方法、车辆,属于车辆技术领域。该系统包括:前桥动力总成和后桥动力总成,所述后桥动力总成包括:后桥驱动电机、单档减速器、离合器、左后半轴、右后半轴和控制器,所述离合器包括左离合器和右离合器;所述后桥驱动电机提供的后驱动力经过所述单档减速器进行减速增扭后,通过所述左离合器和所述左后半轴传递到车辆的左后轮,通过所述右离合器和所述右后半轴传递到车辆的右后轮,以驱动车辆行驶。该系统通过设置离合器替代原有的带有差速锁的差速器,当车辆处于极限工况下,通过控制离合器的状态,从而可以实现两个后轮驱动力的自由分配,提升车辆的脱困能力,使车辆具有更好的安全性和稳定性。
