Title: METHOD FOR EVALUATING THE DYNAMIC LOAD SUPPORTED BY A TYRE BY MEASURING PRESSURE AND LONGITUDINAL ACCELERATION
Abstract:
A method is disclosed for evaluating the variation in dynamic load supported by a tyre, involving a front axle and a rear axle and in which, during a rolling period, the following steps are performed: - the air pressure inside the tyre is measured, - a difference in the load supported by said tyre according to the transfer between the axles of the total load of the vehicle and the position on the vehicle of said tyre are determined and, using a previously defined tyre model, a pressure difference is determined, - a corrected pressure value is determined, - from the corrected pressure values, a reference pressure is determined and, - the difference between the measured pressure and the reference pressure is determined, and the variation in dynamic load supported by the tyre is determined from said tyre model.
