The invention provides a driving loop short-circuit fault control method and device, equipment and a medium, and the method comprises the steps: obtaining the loop current of a driving unit when the driving unit is turned on; according to the loop current and a preset short-circuit current threshold value, whether the driving unit has a short-circuit fault or not is judged; when the driving unit has the short-circuit fault, the driving unit is closed; and after a preset first time, the driving unit is controlled to be turned on or turned off according to the type of the request sent to the driving unit by the vehicle control system within the turn-off time period. According to the method, when the driving unit has a short-circuit fault, the driving unit is immediately closed to protect key electrical elements and the safety and reliability of the whole vehicle; when short-circuit fault recovery is carried out, more reasonable logic judgment is carried out in combination with the instruction sent by the whole vehicle control system in the turn-off protection period, and the operation of maintaining turn-off or direct turn-on is not singly executed any more, so that the control of the driving loop is more flexible, and the safety and reliability of the whole vehicle are ensured.

    本发明提供一种驱动回路短路故障控制方法及装置、设备、介质,该方法包括:当驱动单元打开时,获取驱动单元的回路电流;根据回路电流以及预设的短路电流阈值,判断驱动单元是否存在短路故障;当驱动单元存在短路故障时,关闭驱动单元;经过预设的第一时间后,根据关闭时段内整车控制系统向驱动单元发送的请求的类型,控制驱动单元打开或关闭。该方法在驱动单元存在短路故障时立刻关闭以保护关键电气元件以及整车的安全和可靠性;在进行短路故障恢复时,结合整车控制系统在关断保护期内发的指令进行更加合理的逻辑判断,不再单一的执行维持关闭或直接打开的操作,从而使得驱动回路的控制更加灵活,确保整车的安全性和可靠性。
