Abstract
A method for determining a vacuum degree threshold is provided including: acquiring the current altitude signal of a vehicle; when the current altitude signal is invalid, acquiring a vacuum degree threshold and a standard working time, which correspond to a historical altitude signal received by an electronic vacuum pump of the vehicle last time, the vacuum degree threshold includes a vacuum degree turn-on threshold value and a vacuum degree turn-off threshold; acquiring the actual working time of the vacuum degree threshold corresponding to the historical altitude signal of the electronic vacuum pump when the current working cycle is completed; and when the difference between the actual working time and the standard working time exceeds a preset range, updating, according to the difference, the vacuum degree threshold corresponding to the historical altitude signal, and taking the updated vacuum degree threshold as a target vacuum degree threshold of the next working cycle.
