Abstract:
1. Arrangement to monitor at least one parameter for a number of motor vehicle wheels, comprising: a) a number of detector units, each of which is assigned to a wheel, whereby each detector unit comprises a sensor for recording the at least one parameter and a transmit unit with a transmit antenna, b) at least one receiver antenna comprising a directional characteristic positioned in such a way in the vehicle that, in connection with the field strengths of the signals sent by the individual transmit units at the location of the at least one receiver antenna produces, receive signals of different power in each case for at least two of the transmit units, c) a central evaluation unit which comprises a receive unit, wherein the receive unit is connected to the at least one receiver antenna; and d) an evaluation unit coupled with the central evaluation unit which compares the receive power of a received signal with stored threshold values or ranges of values assigned to one wheel position in each case and assigns the received signal to a wheel position, if the threshold value assigned to this wheel position is exceeded or the receive power lies within the range of values assigned to this wheel position.
