The invention relates to a method and a device for localising the position of at least two emission units, especially for monitoring at least one parameter for a plurality of wheels pertaining to a motor vehicle. The average power of the reception signals of a central evaluation and control unit () is detected. The aim of the invention is to improve the reliability of a correct localisation. To this end, at least two association criteria are used to associate the reception signals or emission units with positions or regions, when the examination of a reliability criterion for the first association criterion does not produce a sufficiently high reliability for the association carried out.

Method and device for localizing the position of at least two emission units, especially for monitoring at least one parameter for a plurality of wheels pertaining to a motor vehicle

The arrangement for monitoring at least one parameter for a number of motor vehicle wheels uses at least one receiver antenna that features a directional characteristic such that at least the signals which are transmitted by detector units located at two different vehicle wheels can be uniquely assigned to the relevant wheel positions as a result of the different receive level. The use of a number of receiver antennas allows either the number of distinguishable detector units to be increased or a redundancy to be created to improve the reliability of the detection.
