The invention discloses a fault diagnosis method and device for a vehicle motor system, a motor controller and a vehicle, and the method comprises the steps: determining the fault type of a fault in the running process of the vehicle under the condition that the motor system is detected to have the fault; wherein the fault type comprises a degradable fault type and a recoverable fault type; when the fault type is a degradable fault type, performing fault degradation processing on the motor system; and when the fault type is a recoverable fault type, performing fault recoverable processing on the motor system. According to the method, when the motor controller detects the downgradable fault type and the recoverable fault type, on the premise that vehicle hardware and driving safety are ensured, the problem that power of the vehicle is frequently lost due to direct shutdown is avoided, and therefore the robustness of a motor system and the reliability of the vehicle are effectively improved.
本发明公开了一种车辆电机系统的故障诊断方法及装置、电机控制器、车辆,其中方法包括:在车辆行驶过程中且检测出电机系统存在故障的情况下,确定故障的故障类型;其中,故障类型包括可降级故障类型和可恢复故障类型;在故障类型为可降级故障类型时,对电机系统进行故障降级处理;在故障类型为可恢复故障类型时,对电机系统进行故障可恢复处理。该方法能够在电机控制器在检测出可降级故障类型和可恢复故障类型时,在确保车辆硬件和行驶安全的前提下,避免直接停机而导致车辆频繁丢失动力的问题,从而有效提高了电机系统的鲁棒性以及车辆的可靠性。
