Method for estimating the dynamic load borne by a vehicle tire
First Claim
1. A method for estimating the dynamic load borne by a tire of a vehicle running along over a given period, wherein the measurement period comprises at least in succession an unladen time interval and a time interval of laden running, wherein the pressure is measured during the period,wherein, at least pressure measurement point, the pressure, known as the reference pressure, of the same tire subjected to a load that is constant and known per time interval is determined, and wherein, at each pressure measurement point, the variation in load is calculated from the difference between the measured pressure and the reference pressure and from a model of the tire devised beforehand and that relates a variation in load to a variation in pressure.

Abstract
The invention relates to a method for estimating the dynamic load borne by a tire of a vehicle running along over a given period, whereby the pressure is measured during the period, at each pressure measurement point, the pressure, known as the reference pressure, of the same tire subjected to a load that is constant and known per time interval is determined, and the variation in load is calculated from the difference between the measured pressure and the pressure, known as the reference pressure, and from a model of the tire devised beforehand and that relates a variation in load to a variation in pressure.
The invention also proposes a method for estimating the load borne by a tire.

- 5. A method for estimating the load borne by a tire of a vehicle running along over a given period, comprising at least successively an unladen time interval and a time interval of laden running, wherein the pressure is measured during the period, wherein, at each pressure measurement point of the unladen phases, the pressure, known as the reference pressure, of the same tire subjected to a constant load is determined, wherein a pressure, known as a reference pressure, is deduced at each pressure measurement point of the phases of laden running of the same tire subjected to a constant load and wherein, at each pressure measurement point, the load is calculated from the difference between the measured pressure and the reference pressure and from a model of the tire devised beforehand and that relates a variation in load to a variation in pressure.
