The invention relates to the technical field of vehicle production and manufacturing, in particular to a vacuum pump system and a failure detection method thereof, a vehicle and a storage medium. Whether the vacuum pump system fails or not can be judged by detecting whether the vacuum degree value of the vacuum pump is out of the vacuum degree threshold range or not, and if the vacuum degree value is out of the vacuum degree threshold range, it is judged that the vacuum pump system fails. On the basis of judging that the vacuum pump system fails, a first current difference value before and after starting of the vacuum pump is obtained, a first failure state of the vacuum pump is determined on the basis of the first current difference value and a preset current change range of the vacuum pump, and failure judgment of the vacuum pump system and judgment of the first failure state of the vacuum pump are combined. The method can confirm that the vacuum pump system is in real failure, can reduce the risk of misjudging the failure of other systems as the failure of the vacuum pump system, and further reduces the misjudgment risk of the failure of the vacuum pump system.

    本发明涉及车辆的生产及制造的技术领域,具体涉及一种真空泵系统及其失效的检测方法、车辆、存储介质。通过检测真空泵的真空度值是否处于真空度阈值范围之外,能够判定真空泵系统是否失效,若真空度值处于真空度阈值范围之外,则判定真空泵系统失效。在判定真空泵系统失效的基础上,通过获取真空泵启动前和启动后的第一电流差值,基于第一电流差值和真空泵预设的电流变化范围,确定真空泵的第一失效状态,结合真空泵系统的失效判定和真空泵的第一失效状态的判定,能够确认真空泵系统为真实失效,便能够减少将其他系统的失效误判为真空泵系统失效的风险,进而减少真空泵系统失效的误判风险。
