Method and device for locating the installation position of vehicle wheels in a motor vehicle
First Claim
1. A method for localizing installation positions of vehicle wheels in a motor vehicle, in which at least one vehicle wheel has wheel electronics, which comprises the steps of:
- repeatedly determining, via the wheel electronics in the vehicle wheel, when the vehicle wheel is in a predetermined angular position;
transmitting a plurality of transmission signals from the wheel electronics in the vehicle wheel, wherein each of the plurality of transmission signals indicates that a rotational position of the vehicle wheel corresponds to the predetermined angular position;
determining, via a plurality of rotation speed sensors in the motor vehicle, information indicating rotation angle positions for the vehicle wheels at instants of time at which the plurality of transmission signals are transmitted;
matching the predetermined angular positions of the vehicle wheel indicated by the plurality of the transmission signals from the wheel electronics in the vehicle wheel with the rotation angle positions determined by one of the plurality of the rotation speed sensors;
determining an installation position of the vehicle wheel by evaluating a number of matches between the predetermined angular positions of the vehicle wheel indicated by the plurality of the transmission signals from the wheel electronics in the vehicle wheel and the rotation angle positions determined by the one of the plurality of the rotation speed sensors.

Abstract
A method locates an installation position of vehicles wheels in a motor vehicle having at least one vehicle wheel containing a wheel electronics unit. The method includes: determining from the wheel electronics unit a first rotational angle position of the vehicle wheel associated with the wheel electronics unit; transmitting a transmission signal with a first piece of rotational angle information dependent on the determined first rotational angle position; determining from the vehicle second rotational angle positions of the vehicle wheels, and depending thereon, providing second rotational angle information. The first rotational angle information is compared with the second rotational angle information. The installation position of the vehicle wheel associated with the wheel electronics unit is determined depending on the comparison. A device is provided for performing the method.
