Method for automatically determining the fitting positions of tires in a motor vehicle
First Claim
1. A method for automatically determining installation positions of wheels in a motor vehicle, the method comprising:
- receiving tire pressure monitoring system data (TPMS) from a direct measure tire pressure monitoring system, wherein the direct measure tire pressure monitoring system having tire pressure measuring devices and transmitting devices for transferring the TPMS date containing tire pressure values and identification numbers of individual wheels;
receiving deflation detection data from an indirect measuring tire pressure monitoring system determining deflation detection data from rotational behavior of the individual wheels, said deflation data containing pressure changes and installation positions; and
determining correlation coefficients from the TPMS data and the deflation data by means of a correlation function.

Abstract
The present device relates to a method for automatically determining the installation positions of wheels in a motor vehicle. The motor vehicle has a direct measure tire pressure monitoring system includes individual wheel tire pressure measuring devices and transmitting devices for the transfer of TPMS data containing tire air pressure values and identification numbers of the individual wheels to a receiving and evaluating device installed in or on the vehicle. The motor vehicle also includes an indirect measuring tire pressure monitoring system determining DDS data containing air pressure changes and installation positions from the rotational behavior of the individual wheels. The method includes determining correlation coefficients from the TPMS data and the DDS data by using a correlation function.
