The invention provides a control method of a vacuum pump and a computer readable storage medium, which relate to the technical field of electric vehicle brake control. The current vacuum degree of thevacuum pump is collected, the vacuum degree and the initial opening threshold value are judged through determining the initial opening threshold value and the initial closing threshold value of the vacuum pump; if the vacuum degree is judged to be larger than or equal to the initial opening threshold value, the process is finished, or otherwise the vacuum pump is enabled to be opened; when the vacuum degree in the vacuum pump is increased after the vacuum pump works, and the increased vacuum degree is smaller than or equal to the initial closing threshold value, the vacuum pump continues to work, or otherwise, the vacuum pump is closed; and when the vacuum pump continues to work and the change rate of the increased vacuum degree is smaller than a preset value and lasts for a certain period of time, the vacuum pump enters a saturation self-learning mode. The problems of heat accumulation in the vacuum pump due to overload work of the vacuum pump and burnout of the vacuum pump due to over-high temperature are solved, and the service life of the vacuum pump is prolonged.
本发明提供了一种真空泵的控制方法及计算机可存储介质,涉及电动汽车制动控制技术领域,通过确定真空泵的初始开启阈值与初始关闭阈值;采集真空泵的当前真空度并判断真空度与初始开启阈值的大小,若判断出真空度大于或等于初始开启阈值,流程结束,否则真空泵使能开启;当真空泵工作后真空泵内的真空度增加,且增加后的真空度小于或等于所述初始关闭阈值,则真空泵继续工作,否则真空泵关闭;当真空泵继续工作且增加后的真空度的变化率小于预设值并持续一定时间,则真空泵进入饱和度自学习模式。通过本发明解决了真空泵超负荷工作,导致真空泵内热积累,温度过高造成真空泵烧毁的问题,提高了真空泵的使用寿命。
