Abstract

A method for allocating transmitters and receiving antennas in tire pressure monitoring systems which consist of a pressure sensor, a transmitter, and a transmitting antenna at each wheel, of a receiving antenna respectively allocated to them on the body, and of an electronic receiving and analysis system connected thereto via cables. In this, an identifier characterizing the wheel is allocated to each transmitter, and the signals are forwarded to the central electronic receiving and analysis system. The method comprises the steps of recording the intensities of the signals received by the respective receiving antennas and deriving from various transmitters, under the signals' identifiers; comparing the intensities of the signals of different identifiers received by one and the same receiving antenna, such that multiple successively received signals are taken into account in the intensity comparison; and lastly, selecting the transmitter identifier having the greatest intensity at a receiving antenna and allocating it to that receiving antenna.
