Tire state monitoring method for detecting e.g. irregular wear of tire of car, involves comparing frequency samples with gauges, and producing alerts in case of exceedance of gauges by values of frequency samples, respectively

摘要

The method involves continuously or periodically producing instantaneous measurements (MES-1-MES-4) of forces applied to wheels by using sensors (CAPT-1-CAPT-4), respectively. Frequency samples (EF-1-EF-4) are obtained for the wheels by Fourier transformation of the measurements, and are compared with gauges (G1-G4), respectively. Alerts (AL-1-AL-4) are produced in case of exceedance of the gauges by values of the frequency samples, respectively.
