Brake pad abrasion early warning system and method based on vehicle pipeline pressure

Abstract

The invention discloses a brake pad abrasion early warning system and method based on vehicle pipeline pressure; the system comprises a vehicle, a server and a mobile terminal; the vehicle comprises the following units: a detection module used for detecting whether a vehicle CAN bus has a brake signal or not; a timing module used for starting timing if the brake signal exists, thus obtaining a brake time; an acquisition module used for collecting vehicle brake pipeline pressure information, wheel gear ring number of pulse and speed at a sampling period interval if the brake time is bigger than a first preset time; a control module used for calculating the brake pad abrasion in each sampling period according to the brake pipeline pressure information, wheel gear ring number of pulse and speed collected in each sampling period, obtaining the total abrasion of the brake pad in the whole brake process according to the brake pad abrasion of each sampling period, and sending the total abrasion to the server when the vehicle shuts downs; the server used sending early warning prompting to a user through the mobile terminal according to the total abrasion.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an early warning system and method for brake pad wear based on automobile pipeline pressure. Background technique [0002] With the continuous development of the automobile industry and the increasing number of vehicles, more and more vehicles have entered thousands of households. Therefore, the safety of automobiles has also received extensive attention. Relevant studies have shown that when an emergency occurs in a car, an effective car braking system is an important guarantee for avoiding traffic accidents. The effectiveness of the braking system mainly depends on the braking energy generated by the effective friction between the brake pads and the brake discs. Due to the special structure of the car, ordinary drivers cannot independently judge the wear of the brake pads, so they cannot be replaced in time. brake pads. [0003] At present, the existing brake pad wear jud...

AI Technical Summary

Problems solved by technology

[0004] However, the existing problem is that the former has the problem of not being able to judge the wear amount of the current brake pads in real time, which affects the user experience, while the latter is currently only configured on luxury models due to cost and other factors.
