Abstract:
A method for allocating to a vehicle, transmitters of a tire pressure monitoring system which includes a respective pressure sensor, a transmitter, and a transmitting antenna at each of N wheels of the vehicle, at least one receiving antenna respectively allocated on a body of said vehicle to be monitored, and an electronic receiving and analysis system, each of said N wheels includes an identifier which characterizes the individual wheel to the respective transmitter, associated at said wheel so that each respective transmitter emits signals containing the identifier, which signals are forwarded to the central electronic receiving and analysis system, the method comprising the steps of:recording an intensity of each of the signals transmitted from the various transmitters to the receiving antenna, in conjunction with the transmitted signal identifier;comparing the intensities of the signals having different identifiers received by one and the same receiving antenna, wherein multiple successively received signals having the different identifiers are taken into account in the intensity comparison;selecting the N transmitter identifiers with the relatively greatest intensities received at the receiving antenna; andstoring the N transmitter identifiers in the central electronic receiving and analysis system as belonging to the vehicle to be monitored;establishing in the electronic analysis system a list when the vehicle has only a single receiving antenna, and a matrix when the vehicle has a multiplicity of receiving antennas;assigning each of the list places and each of the matrix cells to a combination of a specific receiving antenna and a specific identifier contained in the received signals; andincrementing a value of the list place or the value of the individual matrix cell when a maximum intensity is recorded for the relevant combination of transmitter identifier and receiving antenna.
