Abstract:
1. A method for assigning identification codes that are sent by radio signals by tire pressure monitoring devices disposed at the wheels of a vehicle and received by a receiver provided in or at the vehicle, a first radio signaling being relayed to an evaluation unit connected to the receiver for storing a specific identification code for every wheel position of the vehicle the evaluation unit comparing the stored identification codes with identification codes in subsequently sent first radio signals, whereby for the storage of the identification code of the tire pressure monitoring device of a chosen wheel the specific wheel position intended for the chosen wheel is entered at a control unit, which has a communication link to the evaluation unit, subsequently the tire pressure monitoring device of the chosen wheel is caused to send a first radio signal containing its identification code, this radio signal is received and the therein contained identification code is stored in the evaluation unit or in the control unit at a memory location assigned to the specific wheel position, the first radio signal being sent at preset time intervals or upon tire pressure falling below or exceeding a present pressure threshold, the method comprising: bringing a chosen wheel, prior to mounting the chosen wheel on a predetermined wheel position, into proximity of a trigger transmitter, the trigger transmitter triggering the tire pressure monitoring device of the chosen wheel for causing the tire pressure monitoring device of the chosen wheel to send a radio signal containing its identification code and also insert into the radio signal a special identifier, separate from its identification code, indicating that the radio signal is a response to the reception of the trigger transmitter.
