A control method for suppressing jitter of a drive motor, comprising: acquiring power information of each power assembly in a vehicle (S101); acquiring a current torque capacity of the vehicle, the current torque capacity at least comprising a driving torque capacity and a recovery torque capacity (S102); and in response to a power assembly mode switching request, controlling the torque output of a drive motor on the basis of a required torque of the drive motor and the current torque capacity (S103). The control method can suppress generation and intensification of jitter of the drive motor by dynamically reserving the power capability of a battery and performing dynamic smoothing processing on the current torque capacity of the drive motor, so that the driving experience of a user when the capability of the drive motor reaches the limit is greatly improved. Also disclosed are a control apparatus for suppressing jitter of a drive motor, a storage medium, and an electronic device. La présente invention concer
