Process for detecting anomalies by use of pressure and temperature measurements in a tire-monitoring device
First Claim
Patent Images
1. A process for monitoring parameters relative to wheels of a vehicle, comprising the steps of:
- substantially simultaneously measuring pressure and temperature values in tires mounted on each of the wheels of the vehicle;
calculating a ratio of the measured pressure to the measured temperature for each of the tires;
comparing said ratio for one of the tires with said ratio for at least another one of the tires; and
outputting an alarm when a result N of said comparison deviates from a predetermined range of values.

Abstract
In order to monitor gas leakage in the tires of a vehicle, absolute gas psure and temperature in the tires are first simultaneously measured. A ratio of the measured pressure to the measured temperature for reach of the tires is then calculated. The calculated ratios are then compared to produce an indicator N and an alarm is issued when this indicator N deviates from a predetermined range of values.
