Abstract

A method for processing signals of a tire pressure monitoring system on vehicles on each of whose N wheels (R1 through R5) a transmitter is mounted and a reception antenna (1 through 5) which is connected to the input of a common receiver (8) is allocated to each transmitter in its vicinity, the transmitters transmitting, at time intervals, data telegrams which contain an individual identifier and a data portion following the latter. The signals received simultaneously from the reception antennas (1 through 5) and having the same identifier are conveyed in summed fashion to the receiver (8), alternately from all N reception antennas (1 through 5) and from N-1 reception antennas (1, 2, 4, 5), such that the one reception antenna (3) whose signal is blanked out of the sum of the signals is selected by cyclical transposition from the total number N of reception antennas (1 through 5). Then the intensity of the summed signals is determined, the intensity of the sums of N-1 signals is compared in each case to the intensity of the sum of N signals, and an identification is made of that reception antenna (3) from which the signal has come whose blanking from the signal sum brings about the greatest intensity loss (D1 through D5). Lastly, the signal having the relevant individual identifier is allocated to that reception antenna (3) and to the wheel (R3) allocated to it.
