Method of allocating transmitters of a tire pressure monitoring system to a particular vehicle

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;
• and
• storing the N transmitter identifiers in the central electronic receiving and analysis system as belonging to the vehicle to be monitored;
• examining the signals from each one of the transmitters for fluctuations in the signal level and wherein the transmitters whose signals are received with fluctuating signal levels as a result of vehicle motion are allocated to running wheels, whereas any transmitters whose signals are received with a signal level which does not fluctuate as a result of vehicle motion are one of allocated to at least one onboard spare wheel, or are left out of consideration.

• examining the signals from each one of the transmitters for a temperature rise, wherein
• signals indicating a temperature rise as a result of vehicle motion are allocated to running wheels, whereas signals without indication of a temperature rise are allocated to at least one onboard spare wheel, or are left out of consideration.
