The invention discloses an anti-galloping control method, device and equipment and a medium, and belongs to the technical field of vehicles. The method comprises the steps of obtaining the rotating speed of a driving motor of a vehicle; according to the rotating speed of the driving motor, the vehicle speed abrupt change rate of the vehicle is determined; and if the vehicle speed abrupt change rate is larger than or equal to a preset abrupt change rate threshold value, the output torque of the vehicle is reduced to be preset limiting torque. According to the method, under the conditions that the endurance mileage of the whole vehicle is not influenced and the cost of parts is not increased, the risk that the transmission shaft and other structural parts are damaged or broken due to galloping is reduced.
本发明公开了一种防飞车控制方法、装置、设备及介质,属于车辆技术领域。该方法包括:获取车辆的驱动电机转速;根据所述驱动电机转速,确定所述车辆的车速突变率;若所述车速突变率大于等于预设的突变率阈值,则将所述车辆的输出扭矩降低为预设的限制扭矩。该方法在不影响整车续航里程且不增加零部件成本的情况下,降低飞车导致传动轴等结构件损坏或断裂的风险。
