The invention discloses an anti-lock braking 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 method comprises the steps that under the condition that it is determined that single-wheel anti-lock braking control is conducted on a target wheel, obtaining the wheel cylinder pressure of the target wheel; and according to the wheel cylinder pressure, controlling the slip rate of the target wheel to be within a preset slip rate range by adjusting the hydraulic braking force and the energy recovery braking force of the target wheel. According to the method, the anti-lock braking control strategy is set for the hub motor driving type electric vehicle, the anti-lock braking effect of the electric vehicle is guaranteed, meanwhile, energy consumption in the anti-lock braking control process can be reduced, and the driving distance of the electric vehicle is increased.

    本发明公开了一种电动汽车的制动防抱死控制方法、装置、设备及电动汽车,电动汽车的每一车轮上分别设置有轮毂电机,方法包括:在确定对目标车轮进行单轮防抱死控制的情况下,获取所述目标车轮的轮缸压力;根据所述轮缸压力,通过调节所述目标车轮的液压制动力和能量回收制动力,控制所述目标车轮的滑移率处于预设滑移率范围。本发明的方案针对轮毂电机驱动型电动汽车,设置了制动防抱死控制策略,在保证电动汽车的制动防抱死效果的同时,能够降低制动防抱死控制过程的能量消耗,提升电动汽车的续驶里程。
