摘要： A method for determining a maximum coefficient of friction μmax between a tire and an underlying surface entails empirically determining a reference curve μref(S) of a coefficient of friction μref as a function of a slip S between the tire and an underlying reference surface, determining a first momentary slip S1 for the tire and a first momentary coefficient of friction μ1 between the tire and the underlying surface at a first instant t1, determining a second momentary slip S2 for the tire and a second momentary coefficient of friction μ2 between the tire and the underlying surface at a second instant t2, 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 μmax between the tire and the underlying surface by transforming the reference curve μref(S) on the basis of the slope of the curve μ(S). With the aid of the vehicle devices present in any event in modern motor vehicles it is possible to use the information provided by the vehicle devices to be able to compute the momentary slip S and the momentary coefficient of friction μ. By comparing the momentary curve μ(S) that can be determined from the measuring points (μ1; S1) and (μ2; S2) with the empirically determined reference curve μref(S) it is possible using a suitable mathematical method to very accurately estimate, in particular interpolate, the maximum coefficient of friction μmax for the momentary material pairing of the tire with the underlying surface.

摘要： A method and an apparatus for determining the mileage of a tire, include measuring a first current mileage over a limited period a first time, measuring a second current mileage over a limited period a second time, providing a measurement-free rest period between the first measurement and the second measurement, and estimating the mileage during the rest period on the basis of the first current mileage and/or the second current mileage. In addition, the method is repeated, with the already performed second measurement replacing the first measurement. Since a supply of power is not needed or at least can be significantly reduced during the rest period, the power requirement for mileage determination during the life of the tire can be significantly reduced, which allows simplified supply of power for mileage determination.
