System and method for detecting thickness of automobile brake pad in real time

Abstract

The invention discloses a real-time detection system and a detection method for the thickness of an automobile brake pad, belonging to the field of automobile brake systems. The brake caliper of the present invention is equipped with two eddy current sensors, which are used to detect the thickness signal of the brake pad in real time. The current signal is converted into a voltage signal, and the sampling resistor is connected to the input terminal of the signal processing module. The signal processing module is used to calculate the thickness of the brake pad. The display module is connected to the signal processing module to display the thickness information of the brake pad. And the output terminal of the signal processing module is connected with an audible and visual alarm device. The invention has simple structure and high measurement accuracy, can provide more key information compared with the brake pad wear detection system based on the contact switch principle, is convenient to implement, has high versatility, and increases the safety control ability of the driver.

Description

technical field [0001] The invention relates to the technical field of automatic detection and control of an automobile brake system, and more specifically relates to a real-time detection system and a detection method for the thickness of an automobile brake pad, which is suitable for accurate real-time detection of the thickness of an automobile brake pad. Background technique [0002] Cars have entered people's daily life, and the safety of cars has increasingly become a factor that car manufacturers and consumers pay more attention to. According to statistics, more than 70% of the causes of traffic accidents are related to poor braking, so the braking system of a car is very important to driving safety. If the integrity of the braking system can be detected in time, driving safety will be greatly improved and traffic accidents will be reduced. incidence rate. [0003] Looking at the instrument system and safety detection system of passenger cars, most of them do not hav...
