The invention provides a control method and device of a motor controller, the motor controller and a vehicle, and relates to the technical field of vehicles. The method comprises the steps that when the motor controller is in a torque control mode, whether the vehicle is in a slipping working condition or not is judged based on motor rotating speed information and motor torque information; when the vehicle is in the slipping working condition, controlling a motor controller to enter a slipping control mode so as to determine the slipping critical torque according to the motor rotating speed information and the motor torque information; and the target torque of the motor controller is determined according to the slipping critical torque and the current whole vehicle demand torque. Based on the motor rotating speed information and the motor torque information, whether the vehicle is in the slipping working condition or not can be rapidly identified, and further aggravation of slipping can be inhibited. When the vehicle is in the slipping working condition, the target torque is determined based on the slipping critical torque and the current whole vehicle demand torque, and the safety of vehicle operation can be improved.

    本发明提供了一种电机控制器的控制方法、装置、电机控制器及车辆,涉及车辆技术领域,该方法包括:当电机控制器处于扭矩控制模式时,基于电机转速信息和电机扭矩信息判断车辆是否处于打滑工况;当车辆处于打滑工况时,控制电机控制器进入打滑控制模式,以根据电机转速信息和电机扭矩信息确定打滑临界扭矩;根据打滑临界扭矩和当前整车需求扭矩确定电机控制器的目标扭矩。本发明基于电机转速信息和电机扭矩信息能够快速识别车辆是否处于打滑工况,有利于抑制打滑的进一步加剧。当车辆处于打滑工况时,基于打滑临界扭矩和当前整车需求扭矩确定目标扭矩,有利于提高车辆运行的安全性。
