The invention relates to the technical field of vehicles, in particular to a vacuum pump control method and device, a vehicle and a storage medium. The vacuum pump is controlled to work according to the start-stop threshold value of the vacuum pump and the actual air pressure, and the actual air exhaust duration of the vacuum pump in one or more air pressure intervals is obtained; and according to the actual air exhaust duration of each air pressure interval and the corresponding reference air exhaust duration, the actual environment air pressure outside the vacuum tank is calculated, and the start-stop threshold value of the vacuum pump during next work is determined based on the actual environment air pressure. Therefore, the problems that in the prior art, when air pressure information outside a vacuum tank loses efficacy, a controller cannot regulate and control the air pressure in the tank according to environmental changes, the braking capacity of a vehicle in a high-altitude area is likely to be insufficient, and potential safety hazards are caused are solved.

    本发明涉及车辆技术领域,特别涉及一种真空泵控制方法、装置、车辆及存储介质,其中,方法包括:获取真空罐内的实际气压;根据真空泵的启停阈值和实际气压控制真空泵工作,并获取真空泵在一个或多个气压区间的实际抽气时长;根据每个气压区间的实际抽气时长和对应参考抽气时长计算真空罐外的实际环境气压,基于实际环境气压确定真空泵下一次工作时的启停阈值。由此,解决了现有技术中真空罐外气压信息失效时,控制器无法根据环境变化对罐内气压进行调控,使得车辆在高海拔地区可能出现制动能力不足,从而导致安全隐患等问题。
