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

Abstract

The invention discloses a system and a method for detecting the thickness of an automobile brake pad in real time, belonging to the field of automobile brake systems. Each pair of brake calipers of the detection system is provided with two eddy current sensors for detecting the thickness signal of the brake pad in real time; after being sequentially connected with a sampling resistor and a sensor power switch in series, the eddy current sensors are connected into the two sides of a sensor power supply; a current signal collected by the eddy current sensors is converted into a voltage signal by the sampling resistor; the sampling resistor is accessed into the input end of a signal processing module; the signal processing module is used for calculating the thickness of the brake pad; a display module is connected with the signal processing module for displaying the thickness information of the brake pad; and the output end of the signal processing module is connected with an audio and video alarm device. The detection system has the advantages of simple structure, high measurement precision, convenience in implementation and high popularity, compared with a brake pad abrasion detection system using a contact type switch principle, more key information can be provided, and the safety control capability of a driver is improved.

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...
