The invention discloses a control method and device for a vacuum pump in a vehicle, a vacuum boosting system and the vehicle, the vacuum pump is used for providing a vacuum source for a vacuum booster, and the control method comprises the steps that when the vacuum pump has an overheating fault, the current vehicle speed of the vehicle is obtained; judging whether the speed is greater than a preset speed; and if not, the vacuum pump is controlled to stop enabling, and compared with the mode that the vacuum pump is directly controlled to stop enabling when the vacuum pump has the overheating fault, the vacuum pump is controlled to stop when the vehicle speed is low, so that potential safety hazards during vehicle running can be reduced, and the driving experience of a user is improved.
本发明公开了一种车辆中真空泵的控制方法、装置、真空助力系统及车辆,真空泵用于为真空助力器提供真空源,包括:在真空泵出现过热故障时,获取车辆当前的车速;判断车速是否大于预设车速;若否,则控制真空泵停止使能,相较于在真空泵出现过热故障时直接控制真空泵停止使能的方式,在车速较低时控制真空泵停止使能够降低车辆行驶时的安全隐患,提高用户的驾车体验。
