The invention discloses a control method and device for a motor system in a vehicle, the vehicle and a storage medium. The method comprises the steps that the motor rotating speed of a motor system in the vehicle under the operation working condition is obtained; controlling the motor system to enter an active short-circuit state in response to that the motor rotating speed is greater than a first rotating speed threshold; the motor system is controlled to enter an open-circuit state in response to the fact that the motor rotating speed is smaller than a second rotating speed threshold value, and the first rotating speed threshold value is larger than the second rotating speed threshold value. The technical problem that the vehicle shakes seriously when the motor system breaks down is solved.

    本发明公开了一种车辆中电机系统的控制方法、装置、车辆和存储介质。其中,该方法包括:获取车辆中电机系统在运行工况下的电机转速;响应于电机转速大于第一转速阈值,控制电机系统进入主动短路状态;响应于电机转速小于第二转速阈值,控制电机系统进入开路状态,其中,第一转速阈值大于第二转速阈值。本发明解决了电机系统故障时车辆产生严重的抖动现象的技术问题。
