Zusammenfassung:	A method for determining a vacuum degree threshold value. The method comprises: acquiring the current altitude signal of a vehicle; when the current altitude signal is invalid, acquiring a vacuum degree threshold value and a standard working time, which correspond to a historical altitude signal that was received by an electronic vacuum pump of the vehicle last time, wherein the vacuum degree threshold value comprises a vacuum degree turn-on threshold value and a vacuum degree turn-off threshold value, and the standard working time comprises a preset working time of the electronic vacuum pump corresponding to the historical altitude signal; acquiring the actual working time of the vacuum degree threshold value 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 valu
