Abstract

The invention discloses a vehicle vacuum pump control method and device and a vehicle provided with the device, and the method comprises the steps that the vacuum degree of a brake booster and the current atmospheric environment pressure are collected; the brake pedal signals and the current speed of the vehicle are obtained; the vacuum pump opening threshold value and the vacuum pump closing threshold value are obtained according to the vacuum degree of the brake booster, the current atmospheric environment pressure, the brake pedal signals and the current speed of the vehicle. According to the method, the vacuum pump can be controlled according to the vacuum degree of the brake booster, the current atmospheric environment pressure, the brake pedal signals and the current speed of the vehicle, the vacuum pump control accuracy is improved, the reliability of the vehicle is improved, the use requirement of the user is effectively met, and the use experience is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method and device for controlling a vacuum pump of a vehicle and a vehicle having the same. Background technique [0002] At present, electric vehicles can ensure the safety of the vehicle through the vacuum source that can be used by the booster. [0003] In the related technology, the current vacuum degree of the brake booster is first detected by the vacuum degree sensor, and the current atmospheric pressure is obtained by detection by the atmospheric pressure sensor, and secondly, the vacuum pump opening threshold and the vacuum pump shutdown are obtained by the current vacuum degree and the current atmospheric pressure. Threshold, so as to control the on and off of the vacuum pump according to the vacuum pump on threshold and the vacuum pump off threshold. [0004] However, if the vacuum pump opening threshold and the vacuum pump closing threshold are obtained through th...
