The invention relates to the technical field of vehicle motor controllers, and discloses a vehicle motor controller control method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining the current rotating speed of a driving motor of a vehicle when it is detected that a motor system of the vehicle has a preset safety state fault; if the current rotating speed is greater than the preset rotating speed, controlling an IGBT module of a motor controller to enter a first ASC state; wherein the first ASC state is one of an upper bridge ASC state and a lower bridge ASC state; when it is detected that an execution bridge arm corresponding to the first ASC state has a preset bridge arm fault, the IGBT module is controlled to enter a second ASC state; wherein the second ASC state is the other one of the upper bridge ASC state and the lower bridge ASC state. Therefore, when it is detected that the execution bridge arm corresponding to the first ASC state breaks down, the first ASC state is switched to the second ASC state, it can be guaranteed that the ASC state lasts for enough time, and good short-circuit protection is carried out.

    本申请涉及车辆的电机控制器技术领域,公开了一种车辆电机控制器的控制方法、装置、电子设备及存储介质,包括:检测到车辆的电机系统具有预设安全状态故障,则获取车辆的驱动电机的当前转速;若当前转速大于预设转速,则控制电机控制器的IGBT模块进入第一ASC状态;其中,第一ASC状态为上桥ASC状态与下桥ASC状态中的一者;检测到第一ASC状态对应的执行桥臂具有预设桥臂故障,则控制IGBT模块进入第二ASC状态;其中,第二ASC状态是上桥ASC状态与下桥ASC状态中的另一者。因此,在检测到第一ASC状态对应的执行桥臂发生故障时,会将第一ASC状态切换至第二ASC状态,能够保证ASC状态持续足够的时间,以进行良好的短路保护。
