Abstract

The embodiment of the invention provides a detection method, device and brake switch of a brake system. The detection method, device and brake switch of the brake system are applied to a centralized system of a vehicle. The vehicle includes a brake system and an engine. The method includes the steps of receiving a brake system detection request (the brake system detection request indicates the target rotating speed of the engine), detecting the brake parameters of the brake system when it is detected that the current rotating speed of the engine is matched with the target rotating speed; analyzing the brake parameters to obtain the brake state mode of the brake system, realizing the brake state detection of the whole vehicle brake system and solving the problem of vehicle potential hazard due to abnormal vehicle brake system braking.

Description

technical field [0001] The invention relates to the technical field of braking systems, in particular to a detection method and device for a braking system and a braking switch. Background technique [0002] In order to improve the braking ability of the vehicle (especially the heavy-duty vehicle), the national standard stipulates that the vehicle must be equipped with a braking system. Among them, the braking system refers to a series of special devices that can forcibly reduce the driving speed of the vehicle. The main function of the braking system is to slow down or even stop the vehicle in motion, and to keep the speed of the vehicle running downhill stable. To keep the stopped vehicle still, etc. [0003] However, although the prior art can improve the braking capacity of the vehicle by configuring the braking system, there is still the problem of potential safety hazards in the vehicle caused by abnormal braking of the braking system of the vehicle. [0004] Therefo...
