Abstract

The invention discloses a system for monitoring the thickness of a brake pad in real time. The system comprises a distance sensor for detecting a gap between the brake pad and a brake disc, a microprocessor, a display and an alarm, wherein the distance sensor is installed at a position on the brake disc which is in contact with the brake pad. The display and the alarm are installed in a cab of anautomobile; the distance sensor is a laser ranging sensor; the microprocessor wirelessly transmits signals with the display and the alarm; and the microprocessor receives a distance signal between thebrake pad and the brake disc, converts the distance signal into brake pad thickness data for transmission to the display, and determines whether the current thickness is in a dangerous state. The system and method for monitoring the thickness of the brake pad in real time are simple and practical, the thickness of the brake pad is visually displayed through the display, and the current wear conditions of the brake pad and whether the brake pad needs to be replaced are judged.

Description

technical field [0001] The invention relates to a system and method for monitoring the thickness of a brake pad, belonging to the technical field of automobile brakes. Background technique [0002] In people's daily life, automobiles have become more and more common and become an indispensable means of transportation, and consequently, automobile safety has increasingly become the focus of attention of automobile manufacturers and consumers. In automobiles, brake pads are wearing parts, and people need to check the wear of the brake pads to determine whether they need to be replaced. If the brake pads are severely worn and the driver fails to detect and replace the brake pads in time, it may cause potential safety hazards such as brake failure. [0003] Disc brakes are widely used in current automotive products. The thickness measurement of disc brake pads is mainly through visual inspection and disassembly measurement, or to measure the degree of wear according to the mile...
