The invention discloses an electric vehicle flying protection method, equipment and device, and a storage medium. The method comprises the following steps: obtaining an original motor rotating speed,and determining a rotating speed difference value according to the original motor rotating speed; and judging whether the rotating speed difference value is greater than a preset threshold value or not, counting duration that the rotating speed difference value is greater than the preset threshold value when the rotating speed difference value is greater than the preset threshold value, determining a target output torque according to the duration and the original motor rotating speed, and carrying out electric vehicle flying protection according to the target output torque. In the invention, the target output torque is determined according to the torque difference value and the duration, and the electric vehicle flying protection is carried out according to the target output torque so thatthe output torque can be controlled to carry out the electric vehicle flight protection.

    本发明公开了一种电动车腾空保护方法、设备、存储介质及装置,该方法包括:获取原始电机转速,根据所述原始电机转速确定转速差值,并判断所述转速差值是否大于预设阈值,在所述转速差值大于预设阈值时,统计所述转速差值大于所述预设阈值的持续时长,根据所述持续时长以及所述原始电机转速确定目标输出扭矩,并根据所述目标输出扭矩进行电动车腾空保护;本发明将扭矩差值以及持续时长确定目标输出扭矩,并根据目标输出扭矩进行电动车腾空保护,从而能够对输出扭矩进行控制以进行电动车腾空保护。
