Embodiment 1
[0053] This embodiment provides a control method for a vacuum pump, such as figure 1 As shown, the methods include:
[0054] S110. Obtain the first current pumping rate of the vacuum pump. When it is determined that the first current pumping rate is less than the preset first reference rate, continue to obtain the pumping time of the vacuum pump; the first reference rate is the vehicle The minimum pumping rate of the vacuum pump in plain areas;
[0055] As the altitude increases, the atmospheric pressure decreases regularly, and the pumping rate of the vacuum pump also changes regularly. The average altitude increases by 1Km, and the atmospheric pressure decreases by about 10Kpa. Based on this, when the vehicle is running, obtain the first current pumping rate of the vacuum pump, and when it is determined that the first current pumping rate is less than the preset first reference rate, continue to obtain the pumping time of the vacuum pump, if the pumping time is less than or...
Embodiment 2
[0102] This embodiment provides a control device for a vacuum pump, such as figure 2 As shown, the device includes: an acquisition unit 21, a determination unit 22, and a control unit 23; wherein,
[0103] The acquiring unit 21 is configured to acquire a first current pumping rate of the vacuum pump, and when it is determined that the first current pumping rate is less than a preset first reference rate, continue to acquire the pumping time of the vacuum pump; the first The reference rate is the minimum pumping rate of the vacuum pump when the vehicle is in a plain area; if it is determined that the pumping time is longer than the preset reference time, the current vacuum degree of the vacuum pump is obtained;
[0104] The determining unit 22 is configured to determine the current vacuum degree range to which the current vacuum degree belongs, determine the current altitude of the area where the vehicle is located based on the current vacuum degree range, and determine the cu...
