The invention discloses a control method and device of a driving motor, a storage medium and an electric vehicle, the driving motor is powered by a driving battery, the control method of the driving motor comprises the following steps: firstly, starting by adopting a rotating speed control mode and controlling the driving motor to operate, and then obtaining a first instantaneous voltage of the driving battery in the operation process of the driving motor; and if the first instantaneous voltage is smaller than or equal to a preset voltage threshold value, a second instantaneous voltage is obtained after a preset duration is delayed, and when the second instantaneous voltage is still smaller than or equal to the preset voltage threshold value, the driving motor is controlled to stop. The driving motor is controlled to be started in the rotating speed control mode, the voltage difference caused by the driving motor can be reduced, it is guaranteed that the driving motor is natural and smooth when started, two times of voltage judgment are adopted, accurate battery data can be determined, then real data of the driving battery is provided for a user, and the use experience of the user is improved.

    本发明公开了一种驱动电机的控制方法与装置、存储介质、电动车辆,其中,驱动电机由驱动电池进行供电,驱动电机的控制方法首先采用转速控制模式启动并控制驱动电机运行,然后在驱动电机的运行过程中获取驱动电池的第一瞬时电压,如果该第一瞬时电压是小于或等于预设电压阈值的,则在延迟预设时长之后再获取第二瞬时电压,并在第二瞬时电压依旧小于或等于预设电压阈值时,则控制驱动电机停机。本发明通过转速控制模式控制驱动电机启动,能够降低驱动电机导致的电压压差,保证驱动电机启动时自然平顺,并且采用两次电压判断,可以确定出准确的电池数据,进而向用户提供驱动电池的真实数据,以提高用户的使用体验。
