Abstract: The disclosure relates to a method for monitoring behavior of a tire of a vehicle in a rolling condition of the tire, comprising the steps of: acquiring a signal representative of an acceleration of a specified point of the tire, deriving from the signal a curve which represents a profile of the acceleration of the point during a revolution of the tire, determining a leading portion and a trailing portion of the curve, corresponding to an entry of the point into a footprint region of the tire and corresponding to an exit of the point from the footprint region of the tire, respectively, determining a first measure of a volatility of the signal in the leading portion and a second measure of a volatility of the signal in the trailing portion, and determining an indication of the behavior of the tire based on the first measure and the second measure.

Abstract: An aspect of the invention relates to a method for the radio-oriented optimization of wheel monitoring in a vehicle equipped with vehicle wheels, wherein the monitoring of at least one of the vehicle wheels is prompted by an electronic wheel unit arranged on the relevant vehicle wheel capturing at least one wheel operating parameter of the vehicle wheel, and radio signals containing information about the at least one captured wheel operating parameter being transmitted for a respective wheel rotational position of the vehicle wheel, stipulated by the electronic wheel unit, wherein the radio signals are received and evaluated by a control device of the vehicle and wherein the radio-oriented optimization of the wheel monitoring is prompted by the electronic wheel unit being used to transmit multiple radio signals for different wheel rotational positions, wherein the radio signals are received by means of the control device and rated in respect of their respective radio signal strength, wherein the control device is used to transmit an optimization radio signal to the electronic wheel unit, wherein the optimization radio signal contains optimization information formed on the basis of the rating of the radio signals, and wherein the electronic wheel unit is used to receive the optimization radio signal, and the optimization information contained therein is taken into consideration for the stipulation of the wheel rotational position of the vehicle wheel for radio signals that are to be transmitted subsequently.

Abstract: A method and a device for determining loads on vehicle's wheels, each with a tire, is disclosed. A deformation measured value and a pressure measured value for each tire, and at least one acceleration measured value for the vehicle are detected. For the respective wheels, dynamic wheel loads are calculated according to a first model and static wheel loads are calculated according to a second model. The second model comprises at least one model parameter calculated by statistical analysis of the calculated dynamic wheel loads, the calculated static wheel loads, and the detected at least one acceleration measured value. The at least one acceleration measured value is redetected and the dynamic wheel loads are recalculated from the previously calculated static wheel loads and the at least one detected acceleration measured value according to the second model using the previously calculated at least one model parameter of the second model.

Abstract: The invention relates to a method for determining a wheel load (WL) acting on a tire (1) of a vehicle, comprising: a) determining a footprint (L) of the tire (1), b) receiving a tire information (ti) that identifies a type of the tire (1) and/or characterizes physical properties of the tire (1) as such, c) receiving tire operation conditions (toe) based on a measurement, d) selecting one of a plurality of predetermined calculation models (mod(ti)) based on the received tire information (ti), wherein each of the predetermined calculation models (mod(ti)) defines the wheel load (WL) as a function of the footprint (L) and the tire operation conditions (toe) for a respective tire type and/or respective physical properties of the tire (1) as such, e) calculating the wheel load (WL) based on the determined footprint (L) and the received tire operation conditions (toe), using the selected calculation model (mod(ti)). Further, a corresponding system (10) for determining a wheel load (WL) is proposed. Advantageously, the invention can be employed very universally and can deal with the problem of varying tire characteristics.
