The invention relates to the technical field of vehicles, and discloses a control method of a vehicle vacuum pump, a vehicle and a computer readable storage medium, and the method comprises the following steps: obtaining the pressure intensity in a vacuum tank when the vacuum pump works; after the vacuum pump works for the preset maximum working time or when the change rate of the pressure intensity is smaller than a preset value and the pressure intensity in the vacuum tank is smaller than the current closing pressure intensity, the vacuum pump is controlled to stop working; updating the current closing pressure according to the maximum pressure in the vacuum tank when the vacuum pump works and a preset relation; wherein the preset relation comprises the relation between the maximum pressure intensity and the closing pressure intensity of the vacuum tank when the vacuum pump works at different altitudes. In conclusion, even if the pressure intensity in the vacuum tank does not reach the current closing pressure intensity, the vacuum pump can be controlled to be closed, and the current closing pressure intensity can be updated. Therefore, the service life attenuation and cost of the vacuum pump can be reduced, and the actual requirement for the closing time of the vacuum pump can be met.

    本申请涉及车辆技术领域,公开了一种车辆真空泵的控制方法、车辆及计算机可读存储介质,该方法包括:在真空泵工作时获取真空罐内的压强;在真空泵工作预设最大工作时间后或压强的变化率小于预设值,且真空罐内的压强小于当前关闭压强时,控制真空泵停止工作;根据真空泵工作时真空罐内的最大压强以及预设关系更新当前关闭压强;其中,预设关系包括不同海拔下真空泵工作时真空罐的最大压强与关闭压强之间的关系。综上,即使真空罐内的压强没有达到当前关闭压强,也能够控制真空泵关闭,并且能够对当前关闭压强进行更新。因此,能够降低真空泵的寿命衰减以及成本,且能够满足对真空泵关闭时间的实际需求。
