The invention discloses a traction force control method, device and equipment of an electric vehicle, and the electric vehicle, each wheel of the electric vehicle is provided with a hub motor, and the control method comprises the steps that under the condition that it is determined that single-wheel traction force control is conducted on a target wheel, the braking torque of the target wheel is obtained; and according to the braking torque, the slip rate of the target wheel is controlled to be within a preset slip rate range by adjusting the wheel cylinder pressure of the target wheel and the driving torque output by a hub motor of the target wheel. The method can be suitable for the hub motor driving type electric vehicle, and traction force control over the hub motor driving type electric vehicle is achieved.

    本发明公开了一种电动汽车的牵引力控制方法、装置、设备及电动汽车,所述电动汽车的每一车轮上分别设置有轮毂电机,所述控制方法包括:在确定对目标车轮进行单轮牵引力控制的情况下,获取所述目标车轮的制动力矩;根据所述制动力矩,通过调节所述目标车轮的轮缸压力和所述目标车轮的轮毂电机输出的驱动力矩,控制所述目标车轮的滑移率处于预设滑移率范围。本发明的方案能够适用于轮毂电机驱动型电动汽车,实现了对轮毂电机驱动型电动汽车的牵引力控制。
