The invention discloses a slip control method and device for a pure electric vehicle and electronic equipment, and the method comprises the following steps: an obtaining step: obtaining a wheel speed signal of each wheel of the vehicle; a calculation step: determining the reference speed of the vehicle based on the wheel speed signal of each wheel, and calculating the actual slip amount of each driving wheel of the vehicle; a brake torque control step of adjusting the brake torque applied to the drive wheels on the basis of the difference between the slip threshold of each drive wheel and the actual slip amount; and a target rotating speed control step: acquiring a motor target rotating speed of the vehicle based on the reference vehicle speed and the average slip threshold, and controlling the motor according to the target rotating speed. The slip control method can fully utilize the ground adhesive force, reduce the slip of the driving wheels and maintain the direction stability of vehicle driving.
本发明一种用于纯电动车辆的滑移控制方法、装置及电子设备,包括如下步骤:获取步骤,获取车辆的各个车轮的轮速信号;计算步骤,基于各个车轮的轮速信号确定车辆的参考车速,并计算得到车辆的各个驱动轮的实际滑移量;制动扭矩控制步骤,基于各个驱动轮的滑移门限与实际滑移量的差来调整施加于驱动轮的制动扭矩;以及目标转速控制步骤,基于参考车速以及平均滑移门限获取车辆的电机目标转速,并根据该目标转速控制电机。该滑移控制方法能充分利用地面附着力,减小驱动轮的打滑,维持车辆行驶的方向稳定性。
