Abstract

The invention provides an air leakage detection method and device, a storage medium and a vehicle. The method includes the steps that the air leakage state of each pneumatic system of the vehicle is detected according to a preset sequence; the air leakage state of any pneumatic system is detected, wherein a signal value of a pressure switch of the pneumatic system is obtained to determine whetherthe pneumatic system has an inflation request or not; and if the pneumatic system has the inflation request, the air leakage state of the pneumatic system is judged according to the air using state ofthe pneumatic system. According to the provided scheme of the air leakage detection method, micro-air leakage or occasional air leakage can be identified, judged and located.

Description

technical field [0001] The invention relates to the control field, in particular to an air leakage detection method, device, storage medium and vehicle. Background technique [0002] The air compressor (air compressor) is the supply equipment of compressed air and the power source of the pneumatic system on the vehicle. Commercial vehicles and some passenger vehicles equipped with air suspensions use compressed air as the power source for braking systems, air spring suspensions or door control systems. Among them, air spring suspension equipment is a pneumatic system equipment that uses air source on commercial vehicles and passenger vehicles. It is commonly used in passenger cars, especially off-road vehicles or all-road vehicles, while in commercial vehicles, whether it is a level adjustment device controlled by a normal height valve or a level adjustment device with a height sensor and an electronic control unit, sufficient air is required. The source power guarantees t...
