Abstract

A vehicle tire pressure monitoring system includes a pressure sensor, a transmitter, and a transmitting antenna at each of N wheels of the vehicle, and at least one receiving antenna attached to the vehicle, respectively allocated to each transmitting, antenna. The receiving, antenna is connected to an electronic receiving, and analysis system which determines whether a signal belongs to the local vehicle by allocating an identifier characterizing the individual wheel to its transmitter. Emitted signals contain the identifier and are forwarded to the central electronic receiving and analysis system, which records the signal intensities under the signal's identifier, compares the intensities, selects those N transmitter identifiers with the greatest intensities, then stores the N transmitter identifiers as belonging to the vehicle.
