Abstract
A method for determining a maximum coefficient of friction μbetween a tire and an underlying surface entails empirically determining a reference curve μ(S) of a coefficient of friction μas a function of a slip S between the tire and an underlying reference surface, determining a first momentary slip Sfor the tire and a first momentary coefficient of friction μbetween the tire and the underlying surface at a first instant t, determining a second momentary slip Sfor the tire and a second momentary coefficient of friction μbetween the tire and the underlying surface at a second instant t, computing a slope of the curve μ(S) of the coefficient of friction μ as a function of slip S, and computing the maximum coefficient of friction μbetween the tire and the underlying surface by transforming the reference curve μ(S) on the basis of the slope of the curve μ(S).
