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

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