Abstract:
A method and device detect the imbalance of a vehicle wheel. The method includes measuring a rotation speed of the wheel while the vehicle is moving, and calculating a filtered value by applying at least one step of band-pass filtering to the measured rotation speed value of the wheel. A position of a pass-band of the band-pass filtering step is offset while moving as a function of the rotation speed of the wheel.
Abstract:
A method for monitoring a tire of a motor vehicle, implemented in a wheel and including: measuring a temperature of the tire, measuring a pressure of the tire, calculating a variation, in absolute value, of the ratio between the measured pressure and the measured temperature, comparing the calculated variation to a predetermined threshold, and sending an alert message to a computer of the vehicle if the calculated variation is above the predetermined threshold.
