Method for determining vacuum degree threshold, and medium, and electronic device

A non-transitory computer storage medium on which a computer program is stored, wherein the program, when executed by a processor, implements a method comprising:

• obtaining a current altitude signal of a vehicle by a vehicle controller unit;
• obtaining, if the current altitude signal is invalid, a vacuum degree threshold and a standard working time of an electronic vacuum pump of the vehicle corresponding to a historical altitude signal received by the VCU last time, the vacuum degree threshold comprising a vacuum degree turn-on threshold and a vacuum degree turn-off threshold, and the standard working time comprising a predetermined working time of the electronic vacuum pump corresponding to the historical altitude signal;
• obtaining an actual working time of the electronic vacuum pump to complete a current working cycle with the vacuum degree threshold corresponding to the historical altitude signal;
• and
• updating, when a difference between the actual working time exceeds a predetermined range, the vacuum degree threshold corresponding to the historical altitude signal according to the difference, and taking an updated vacuum degree threshold as a target vacuum degree threshold for a next working cycle.
