The invention provides a vehicle anti-skid control method, device and system and a storage medium, and is applied to a power domain controller to obtain the wheel speed of a vehicle in the running process. When it is determined that the vehicle has a slipping trend according to the wheel speed of the wheels, the slipping degree grade of the vehicle is determined based on the wheel speed of the wheels; determining a torque reduction rate corresponding to the slip degree grade, wherein the torque reduction rate is in direct proportion to the slip degree grade; and based on the torque reduction rate, the torque of a driving motor of the vehicle is controlled to be reduced at the torque reduction rate. On the basis of an original power domain controller and an original driving motor on the pure electric truck, the anti-skid function is achieved through software control, no hardware needs to be additionally installed, the anti-skid control strategy is determined by monitoring the wheel speed, all-running-state anti-skid and all-speed-domain anti-skid are achieved, the cost for additionally installing the anti-skid function is reduced, and the safety of the truck is improved.
本说明书提供一种车辆防滑控制方法、装置、系统及存储介质,应用于动力域控制器,获取车辆行驶过程中的车轮轮速;根据所述车轮轮速确定所述车辆具有打滑趋势时,基于所述车轮轮速确定所述车辆的打滑程度等级;确定所述打滑程度等级对应的降扭速率,所述降扭速率与所述打滑程度等级成正比;基于所述降扭速率,控制车辆的驱动电机的扭矩以所述降扭速率降低。即基于纯电动卡车上原有的动力域控制器和驱动电机,通过软件控制实现防滑功能,无需加装任何硬件,通过监测车轮轮速确定防滑控制策略,实现全行驶状态防滑与全速度域的防滑,降低了防滑功能加装的成本,提高了车辆的安全性。
