Method for the Automatic Initialization of Electronic Wheel Systems and Vehicle
First Claim
1. A method for automatic initialization of electronic wheel systems of a tire pressure checking system, which comprises the steps of:
- a) recording signals transmitted by the electronic wheel systems;
b) evaluating the signals received on a basis of signal strength by means of criteria, which are obtained by means of one of the following substeps;
b1) averaging the signal strength of the signals received in question resulting in averaged signal strength values;
b2) comparing a relevant signal strength of the signals received with a predefined threshold value;
b3) calculating at least one of minimum values and maximum values of the signal strength of the signals received;
c) selecting the electronic wheel systems allocated to the tire pressure checking system on a basis of the criteria obtained in the steps bl)-b3)d) automatically initializing selected electronic wheel systems.

Abstract
A method for the automatic initialization of the electronic wheel systems of a tire pressure checking system, performs the now described steps. Record signals are sent by electronic wheel systems. The received signals are evaluated on the basis of their signal strength by using criteria, which are obtained in at least one of the now described substeps. The signal strength in question of the received signals is average, the signal strength in question of the received signals is compared with a predefined threshold value, and the minimum and/or the maximum values of the signal strength of the received signals are calculated. The electronic wheel systems allocated to the tire pressure checking system are selected on the basis of the criteria obtained in the above-mentioned steps. The selected electronic wheel systems are automatically initializated.
