The invention discloses a vehicle anti-skid control method, a motor controller, a system and a storage medium. The method comprises the steps that the motor controller determines whether an anti-skid rotating speed limiting request sent by a vehicle control unit is received or not; if the anti-skid rotating speed limiting request is received, an anti-skid driving mode is started, and whether torque reduction control needs to be conducted on the driving motor or not is determined according to the highest limiting rotating speed and the actual rotating speed of the driving motor; if yes, closed-loop control is carried out on the torque of the driving motor according to the maximum limited rotating speed and the limited torque of the motor; in the anti-skid driving mode, the motor controller automatically determines whether torque reduction control is executed or not according to the maximum limiting rotating speed and the actual rotating speed, closed-loop control is conducted on the torque of the driving motor according to the maximum limiting rotating speed and the motor limiting torque in the torque reduction control process, the torque of the driving motor can be adjusted timely and accurately, and the anti-skid driving effect is improved. Therefore, the real-time performance and effectiveness of vehicle anti-skid control are improved, and the anti-skid effect is improved.
本发明公开了一种车辆防滑控制方法、电机控制器、系统及存储介质,方法包括:电机控制器通过确定是否接收到整车控制器发送的防滑转速限制请求;若接收到防滑转速限制请求,则启用防滑驱动模式,以根据最高限制转速和驱动电机的实际转速,确定是否需要对驱动电机进行降扭控制;若需要,则根据最高限制转速和电机限制扭矩,对驱动电机的扭矩进行闭环控制;本发明中,在防滑驱动模式中,电机控制器自行根据最高限制转速和实际转速确定是否执行降扭控制,并在降扭控制过程中,根据最高限制转速和电机限制扭矩对驱动电机的扭矩进行闭环控制,能够及时、精确调整驱动电机的扭矩,从而提高了车辆防滑控制的实时性和有效性,进而提高了防滑效果。
