The invention provides a distributed dragging torque control method and system and a readable storage medium. The distributed dragging torque control method comprises the steps that when a vehicle is in an energy recovery state, an intelligent integrated braking system IPB detects whether an abnormal wheel in a slipping state exists or not; when an abnormal wheel exists, the IPB sends the slip rate of the abnormal wheel and a torque control instruction to a motor controller; the motor controller controls the torque of the motor of the abnormal wheel based on the slip rate of the abnormal wheel. According to the method and the device, when the wheels slip, the torque of the motor of the abnormal wheels is controlled according to the slip rate of the abnormal wheels, so that the problem of vehicle sideslip instability caused by wheel slip is solved, and the driving stability of the vehicle is improved. Moreover, the torque of the motor of the abnormal wheel is directly controlled through the motor controller, and compared with a torque control mode through IPB, torque control can be completed more quickly.

    本发明提供一种分布式拖滞扭矩控制方法、系统及可读存储介质。分布式拖滞扭矩控制方法包括:当车辆处于能量回收状态时,智能集成制动系统IPB检测是否存在处于打滑状态的异常车轮;当存在异常车轮时,IPB发送所述异常车轮的滑移率以及扭矩控制指令至电机控制器;电机控制器基于所述异常车轮的滑移率对所述异常车轮的电机的扭矩进行控制。通过本发明,当车轮打滑时,根据异常车轮的滑移率对异常车轮的电机的扭矩进行控制,从而消除车轮打滑导致的车辆侧滑失稳问题,提升车辆的行车稳定性。且,是直接通过电机控制器对异常车轮的电机的扭矩进行控制,相较于通过IPB进行扭矩控制的方式,能更快的完成扭矩控制。
