Methods for estimation of tire wear

摘要

A method for controlling the functioning of a tire includes the steps of determining estimations or measurements of the slip G_i and the coefficient of friction mu_i prevailing at such slip for at least one pair "i" of values (G_i, mu_i); determining the corresponding values of the slope alpha_i of the straight line passing through the origin and through each pair (G_i, mu_i); calculating a coefficient B by direct calculation or by a regression from a sufficient number of pairs of (alpha_i, G_i) so as to estimate the value of slope alpha₀ at the origin; and using alpha₀ in an indicator of the longitudinal stiffness of the tread pattern.
