Device and method for distinguishing positions of tire sensors of a double tire system

A method for distinguishing positions of two tire sensors of a double tire on a vehicle, the method comprising the following steps:

• providing a device having an evaluation unit disposed on the vehicle, at least one LF antenna disposed on the vehicle laterally next to the double tire and connected to the evaluation unit for emitting signals with variable power, and tire sensors each associated with a respective tire;
• selecting a transmission power, for transmission of a signal through the LF antenna, high enough to enable reception by the two tire sensors of the double tire;
• transmitting a signal through the LF antenna to the tire sensors;
• checking if both tire sensors have received the signal transmitted by the LF antenna;
• if both tire sensors have received the transmitted signal, gradually reducing the LF transmission power for transmission of the signal through the LF antenna and repeating the transmitting and checking steps until only one tire sensor receives the transmitted signal;
• and
• if only one tire sensor has received the transmitted signal, assigning the receiving tire sensor to a position nearest the LF antenna and assigning the other tire sensor having no longer received the transmitted signal to a position furthest from the LF antenna.
