Abstract

A method for localizing individual wheels and/or wheel identifiers of individual wheels of a double wheel of a motor vehicle includes the following steps: determining the axle of the respective double wheel; determining the motor vehicle side of the respective double wheel; determining the position of the respective double wheel by the position of the axle and the position of the motor vehicle side; determining the direction of travel of the motor vehicle; determining the direction of rotation of the individual wheels and/or wheel identifiers of the respective double wheel; localization of the individual wheels and/or wheel identifiers of the individual wheels by the position of the associated double wheel, the direction of travel of the motor vehicle and the rotational directions of the individual wheels and/or wheel identifiers.

Claims

1. A method of localizing individual wheels and/or wheel identifiers of individual wheels of a double wheel of a motor vehicle, the method which comprises the following steps:

determining an axle of the respective double wheel;

determining a motor vehicle side of the respective double wheel;

determining a position of the respective double wheel by a position of the axle and a position of the motor vehicle side;

determining a direction of travel of the motor vehicle;

determining the rotational direction of the individual wheels and/or wheel identifiers of the respective double wheel; and

localizing the individual wheels and/or wheel identifiers of the individual wheels by the position of the associated double wheel, the direction of travel of the motor vehicle and the rotational directions of the individual wheels and/or wheel identifiers.

2. The method according to claim 1, which comprises determining the axle of the motor vehicle, on which the respective double wheel is arranged, by evaluating different field strengths of radio frequency signals emitted by the wheel electronics systems.

3. The method according to claim 1, which comprises determining the axle of the motor vehicle, on which the overall double wheel is arranged, by way of a signal emitted by a wheel electronics circuit to a control unit, with the signal having been triggered by a trigger signal, and defining the specific axle with the control unit by way of an identifier, which is transmitted with the signal.

4. The method according to claim 1, which comprises determining the motor vehicle side of the motor vehicle, on which the respective double wheel is arranged, by an evaluation of different field strengths of radio frequency signals emitted by the wheel electronics system.

5. The method according to claim 1, which comprises determining the vehicle side of the motor vehicle, on which the overall double wheel is arranged, by way of a signal, emitted by a wheel electronics system to a control unit, with the signal having being triggered by a trigger signal, and defining the specific motor vehicle side with the control unit by way of an identifier, which is transmitted with the signal.

6. The method according to claim 1, which comprises determining the direction of travel of the motor vehicle by acquiring information as to which gear is engaged in the motor vehicle.

7. The method according to claim 1, which comprises determining the rotational direction of the individual wheels and/or wheel identifiers of the respective overall double wheel with an acceleration measurement.
