Abstract:
A method for determining the pressure of a tire of a vehicle being driven at a speed, the tire comprising, arranged in the tire, a pressure sensor and a temperature sensor. The method includes generating a library of ratios between a measurement of the output of the pressure sensor and a measurement of the output of the temperature sensor, the one or more ratios being calculated at different speeds and one ratio being measured at a speed of zero, defining a variation law representative of the variation in the ratios with respect to the acceleration experienced by the pressure sensor, measuring the output of the pressure sensor and the output of the temperature sensor, and obtaining the value of the acceleration experienced by the pressure sensor, and determining the pressure by correcting this measurement with the variation law.
