The embodiment of the invention provides a control method and a control system of a distributed four-wheel-drive electric vehicle. The control method of the distributed four-wheel-drive electric vehicle comprises the following steps: acquiring a reference vehicle speed according to wheel speeds and wheel accelerations of four wheels of the four-wheel-drive electric vehicle; obtaining a target wheel speed according to the reference vehicle speed and a target slip rate, and obtaining original target torques of the four wheels according to the deviation between the target wheel speed and the actual wheel speed; and obtaining the target torques of the four wheels according to the original target torques of the four wheels. The embodiment of the invention provides the control method and the control system of the distributed four-wheel-drive electric vehicle so as to improve the driving stability of the distributed four-wheel-drive electric vehicle.

    本发明实施例提供一种分布式四驱电动车的控制方法及控制系统,分布式四驱电动车的控制方法包括:根据所述四驱电动车的四个车轮的轮速度以及轮加速度获取参考车速;根据所述参考车速与目标滑移率获取目标轮速度,并根据所述目标轮速度与所述实际轮速度的偏差获取所述四个车轮的原始目标扭矩;根据所述四个车轮的原始目标扭矩获取所述四个车轮的目标扭矩。本发明实施例提供一种分布式四驱电动车的控制方法及控制系统,以提升分布式四驱电动车的的驱动稳定性。
