1. A method for allocating transmitters and receiving antennas in tire pressure monitoring systems on vehicles, which systems 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, by allocating an identifier characterizing the wheel to its transmitter, by emitting signals containing the identifier, and by forwarding the signals to the central electronic receiving and analysis system, recording the intensities of the signals received by the respective receiving antennas from various transmitters, under the signals'"'"' identifiers, and allocating the identifier of the signal having the greatest intensity at an antenna to that antenna,characterized in that the intensities of the signals of different identifiers received by one and the same receiving antenna are automatically compared, even with the vehicle in motion, such that multiple successively received signals are taken into account cumulatively in the intensity comparison;

  • and that the transmitter identifier contained in the signal having the greatest intensity at a receiving antenna is selected and allocated to that receiving antenna.
