Verfahren zur Zuordnung von Sendern zu Empfangsantennen bei Reifendrucküberwachungssystemen

摘要

A method is disclosed of allocating transmitters and receiving antennas in tyre-pressure monitoring systems comprising the following elements: a pressure gauge, transmitter and transmitting antenna on each wheel; allocated thereto as appropriate, a receiving antenna on the vehicle body; and a receiving and evaluation electronic system connected to the receiving antenna via cable. An identifier unique to the wheel in question is assigned to each transmitter and the signals are forwarded to the central electronic receiving and evaluation system. The process is characterised by the following process steps: registration of the intensities of the signals originating from the different transmitters and received by the appropriate receiver antennas with their identifiers; comparison of the intensities of signals with different identifiers received by one and the same receiving antenna to ensure that the comparison of intensities is based on a number of consecutively received signals; lastly, selection of the transmitter identifier associated with the greatest intensity at a receiving antenna and assignment thereof to that receiving antenna.
