Design of Indirect Tire Pressure Monitoring System Based on Wheel Speed Signal

Abstract

Keeping the pressure of the automobile tire in the normal working range is an important guarantee for the safety of the automobile. When the tire leaks, the driver should be reminded to check or replace the tire before the potential danger of blowing out. Aiming at the safety problem of commercial vehicle driving, a set of tire pressure monitoring alarm systems is designed by combining the radius method and frequency method. The magneto-electric wheel speed sensor is used to collect and process the tire speed, and then through the data processing, the full range of monitoring each tire’s possible air leakage hazards, such as emergency can be quickly warned, thus providing a reference for the driver’s driving. The experimental results show that the system can effectively improve the accuracy and stability of tire pressure monitoring.
