Abstract
A method for localizing the installation position of wheels in a motor vehicle having at least a first, second and third wheels, includes allocating respective wheel electronics to the wheels for emitting a radio signal with an identifier and allocating at least one vehicle-side rotational angle sensor to at least a first possible installation position. The installation position of the first wheel is determined by output signals of the rotational angle sensor at a first possible installation position. In addition, the installation position of the second and third wheels is determined by measuring the field strength of radio signals with identifiers of the wheel electronics of the second and third wheels by using a vehicle-side receiving device. In this way, precise determination of the location of the wheel electronics can be performed with minimum expenditure on devices, without having to provide a rotational angle sensor on each wheel.

12. A method for localizing the installation position of wheels of a vehicle, the method comprising the following steps:
-
providing the vehicle with at least one first wheel and a second wheel and a third wheel, wheel electronic systems each being allocated to a respective one of the wheels to emit a radio signal with an individual identifier, and at least one vehicle-side rotational angle sensor allocated to at least one first possible installation position; defining the installation position of the at least one first wheel via output signals of the at least one rotational angle sensor at the first possible installation position; determining the installation position of the at least one second and third wheel by measuring a field strength of the radio signals with the individual identifiers of the wheel electronic systems of the at least one second and third wheel by using a vehicle-side receiving device; and allowing the respective installation position to be inferred from the respectively measured field strength, as a measure of a distance from the vehicle-side receiving device to the wheel electronic system of the at least one second and third wheel. - View Dependent Claims (13, 14, 15, 16, 17)
