The invention relates to the braking technology, in particular to a vehicle electronic vacuum pump control method and a vehicle-mounted electronic control unit for implementing the method. According to one embodiment of the invention, the vehicle electronic vacuum pump control method comprises the following steps: obtaining a vacuum level in a vacuum booster; comparing the vacuum level with a control threshold to determine the open-close state of an electronic vacuum pump; and causing the electronic vacuum pump to be in an opened or closed state according to the comparison result, wherein the control threshold is dynamically adjusted according to the current elevation of a vehicle, and the higher the elevation is, the smaller the control threshold is.
