The invention provides a control method of an electronic vacuum pump, which comprises the following steps: acquiring environment information of an environment in which a vehicle is located, determining a closing threshold value of the electronic vacuum pump according to atmospheric pressure in the environment information and a pre-calibrated corresponding relationship between pressure and threshold values, and controlling the electronic vacuum pump when the vacuum degree of the electronic vacuum pump is greater than or equal to the closing threshold value. And switching the electronic vacuum pump to a stalling state. According to the method, the closing threshold value of the electronic vacuum pump is adaptively adjusted in combination with the environment information of the environment where the vehicle is located, the problem that the vacuum degree of the electronic vacuum pump cannot reach the closing threshold value due to environmental influence, and then the electronic vacuum pump is in the working state all the time is solved, the ablation risk is reduced, and the braking force of the vehicle is guaranteed.

    本申请提供了一种电子真空泵的控制方法,包括:获取车辆所处环境的环境信息,根据环境信息中的大气压力以及预先标定的压力和阀值的对应关系,确定电子真空泵的关闭阀值,当电子真空泵的真空度大于或等于关闭阀值时,将电子真空泵切换至停转状态。该方法结合车辆所处环境的环境信息自适应地调整电子真空泵的关闭阀值,避免环境影响导致电子真空泵的真空度无法达到关闭阀值,进而使得电子真空泵一直处于工作状态的问题,降低了烧蚀风险,保障了车辆的制动力。
