Patent ID: 7327233

Claim:
A method of locating the position of wheels ( 2 - 5 ) of a vehicle ( 1 ), which wheels are equipped with an electronic box ( 6 - 9 ) adapted so as to transmit, to a central unit ( 15 ) mounted on the vehicle ( 1 ), signals representative of operating parameters of each wheel comprising, furthermore, a code for identifying the latter, said locating method being characterized in that: the vehicle ( 1 ) is equipped with transmit antennas ( 11 - 14 ; 16 - 19 ) each disposed in such a way as to be positioned in proximity to a wheel ( 2 - 5 ) or to a pair of wheels (( 2 , 4 ), ( 3 , 5 ) ( 2 , 3 ), ( 4 , 5 )), and the central unit ( 15 ) and the electronic boxes ( 6 - 9 ) are programmed in such a way as to implement a locating procedure according to which, successively for each of the transmit antennas ( 11 - 14 ; 16 - 19 ): the central unit ( 15 ) instructs the transmission, by said transmit antenna, of an identification request signal on receipt of which the electronic box ( 6 - 9 ) of each wheel ( 2 - 5 ) positioned in proximity to this transmit antenna is adapted so as to transmit in response a signal comprising this wheel's identifying code, the central unit ( 15 ) instructs, simultaneously with the transmission of the identification request signal, the transmission, by each of the antennas positioned in proximity to the other wheels, of a garbled signal designed to scramble the identification request signal.
