The invention discloses a vehicle fault processing method, device and equipment and a storage medium, and relates to the field of fault processing, and the method comprises the steps: responding to a desaturation fault judgment result of an inverter bridge in a vehicle power system, determining a fault bridge arm based on the desaturation fault judgment result, obtaining the information of a fault register, and storing the information of the fault register; according to the fault register information, phase fault detection is carried out on the fault bridge arm, and a vehicle power system is controlled based on a phase fault detection result; the fault of the power system is detected and positioned based on the desaturation fault judgment result and the fault register information, and the power system is controlled based on the phase fault detection result, so that the vehicle power system is effectively prevented from stopping running when the vehicle power system fails, the whole vehicle is ensured to continuously run, the safety performance of the vehicle is greatly improved, and the safety of the vehicle is improved. The safety of the whole vehicle and personnel is ensured.

    本发明公开了一种车辆故障处理方法、装置、设备及存储介质,涉及故障处理领域,所述方法包括:响应于车辆动力系统中逆变桥的退饱和故障判断结果,基于所述退饱和故障判断结果确定故障桥臂,获取故障寄存器信息,并根据所述故障寄存器信息对所述故障桥臂进行相位故障检测,基于相位故障检测结果对所述车辆动力系统进行控制;由于本申请基于退饱和故障判断结果和故障寄存器信息对动力系统的故障进行检测和定位,基于相位故障检测结果对动力系统进行控制,有效地避免车辆动力系统故障时停止运行,保证整车继续运行,大幅提升车辆安全性能,保障整车和人员安全。
