According to the vacuum pump control method, device and equipment provided by the embodiment of the invention, when the environment pressure sensor breaks down, the standard pressure value is determined based on the historical environment pressure value collected by the environment pressure sensor; after the vehicle executes braking operation, the vacuum pump is controlled to execute exhaust operation based on the standard pressure value and a system pressure value in the vacuum pump, and the system pressure value is collected by a system pressure sensor; and correcting the standard pressure value based on the duration of the exhaust operation. When the environment pressure sensor breaks down, the historical environment pressure value serves as the standard pressure value, the standard pressure value is corrected along with changes of the external environment pressure, normal operation of the vacuum pump can be guaranteed, and the vacuum pump is prevented from breaking down due to frequent starting or continuous operation.
本申请实施例提供的一种真空泵控制方法、装置及设备,当环境压力传感器出现故障时,基于环境压力传感器采集的历史环境压力值确定标准压力值;在车辆执行制动操作后,基于标准压力值以及真空泵内部的系统压力值控制真空泵执行排气操作,系统压力值由系统压力传感器采集;基于排气操作的持续时长对标准压力值进行修正处理。在环境压力传感器出现故障时采用历史环境压力值作为标准压力值,并随着外界环境压力的变化对标准压力值进行修正处理,可保证真空泵正常运行,避免真空泵因频繁启动或持续运行而出现故障。
