The invention discloses an anti-slip control method for a pure electric vehicle wheel. The method comprises the steps of judging whether the wheel is in a suspended state or a slipping state by detecting whether the sudden change of the rotating speed of a driving motor exceeds a specific threshold value within a certain period of time, when the sudden change of the rotating speed of the driving motor exceeds the specific threshold value within the certain period of time, enabling a motor controller MCU to reduce the actual output torque of the driving motor in proportion so as to inhibit further sharp increase of the rotating speed of the driving motor. The invention relates to the technical field of new energy automobile driving motor control. According to the anti-slip control method for the pure electric vehicle wheel, when the wheel slips in the air under special working conditions, torque output of the motor is limited, and motor driving system faults caused by load rejection of the motor are prevented.

    本发明公开了一种纯电动汽车车轮防打滑控制方法,通过检测一定时间内驱动电机转速突变量是否超过特定阈值来判断车轮是否处在腾空或者打滑状态,当一定时间内驱动电机转速突变量超过特定阈值时,电机控制器MCU按比例降低驱动电机的实际输出扭矩从而抑制驱动电机转速的进一步急剧上升,本发明涉及新能源汽车驱动电机控制技术领域。该种纯电动汽车车轮防打滑控制方法,在特殊工况下车轮腾空打滑时,限制电机的扭矩输出,防止电机因抛负载而引发电机驱动系统故障。
