A method for determining the load of a motor vehicle includes the following steps: detecting at least one physical measured variable that depends on the load and generating a measured value that represents the detected measured variable; evaluating the generated measured values in order to determine the load by correlating the generated measured values or the load values determined therefrom with each other in order to produce a correction value from the correlation, with the aid of which an actual load value is determined for the load of the motor vehicle. There is also provided a system for detecting the load of a motor vehicle, and a motor vehicle.

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.

A method for determining a maximum coefficient of friction &#x3bc;between a tire and an underlying surface entails empirically determining a reference curve &#x3bc;(S) of a coefficient of friction &#x3bc;as 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 &#x3bc;between 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 &#x3bc;between the tire and the underlying surface at a second instant t, computing a slope of the curve &#x3bc;(S) of the coefficient of friction &#x3bc; as a function of slip S, and computing the maximum coefficient of friction &#x3bc;between the tire and the underlying surface by transforming the reference curve &#x3bc;(S) on the basis of the slope of the curve &#x3bc;(S).

A tire module for sensing wheel and/or tire state variables is provided. The module includes at least one acceleration switch which determines a wheel state variable and/or a tire state variable. A method for sensing wheel state variables and/or tire state variables is also provided. In the method, a characteristic variable which is a measure of the length of the contact area of the tire or the contact area run-through time is determined by an acceleration switch.

A method used for determining a profile depth or wear on a tread of a tire of a vehicle, and/or a tire characteristic, a magnetic field being detected by a magnetic field sensor disposed in the interior of the tire, particularly in the area of the tread on the tire interior, or at a distance from the tire, particularly in the area of a wheel housing or a wheel well of the vehicle, the magnetic field being transmitted or changed by at least one indicator element disposed in the tread on the tire exterior. The current wear state of the tread and/or the tire characteristic, particularly a tire type and/or permissible top speed, is determined based on output signals of the magnetic field sensor. The invention further relates to tires.
