The invention relates to the technical field of automobiles, in particular to an anti-flying method and device for a vehicle, the vehicle and a storage medium. The method comprises the steps that the current rotating speed of a driving motor is obtained from a motor controller; calculating the rotating speed change rate of the driving motor according to the current rotating speed of the driving motor and the actual rotating speed of the driving motor at the previous moment; when the rotating speed change rate exceeds the preset interval, the vehicle is controlled to enter an anti-flying working condition, anti-flying torque is determined according to the actual output torque of the driving motor, output of the driving motor is controlled according to the anti-flying torque, and the anti-flying torque is smaller than the actual output torque. Therefore, the problems that hardware needs to be additionally added, the anti-flying cost is high and the like in the mode that the anti-flying mode of the vehicle is achieved through the slip rate in the related technology are solved.

    本申请涉及汽车技术领域,特别涉及一种车辆的防腾飞方法、装置、车辆和存储介质,其中,方法包括:从电机控制器获取驱动电机的当前转速;根据驱动电机的当前转速和前一时刻的驱动电机的实际转速计算出驱动电机的转速变化率;以及在转速变化率超出预设区间时,控制车辆进入防腾飞工况,根据驱动电机的实际输出扭矩确定防腾飞扭矩,并按照防腾飞扭矩控制驱动电机输出,其中,防腾飞扭矩小于实际输出扭矩。由此,解决了相关技术中利用滑转率实现车辆的防腾飞的方式,需要额外增加硬件,防腾飞成本较高等问题。
