Patent ID: 7683766

Claim:
Method of locating the position of wheels ( 2 - 5 ) of a vehicle ( 1 ) equipped with an electronic module ( 6 - 9 ) designed to transmit, to a central processing unit ( 11 ) mounted on the vehicle ( 1 ), signals representative of operating parameters of each wheel comprising, in addition, an identification code of the latter, said locating method consisting in equipping the vehicle ( 1 ) with transmitting antennas ( 12 - 14 ) each positioned in such a way as to present a coverage area in which at least one wheel ( 2 - 5 ) is located, and being characterized in that it consists in applying a locating procedure according to which, in succession for each of the transmitting antennas ( 12 - 14 ): the central processing unit ( 11 ) orders n successive transmissions, by said transmitting antenna, of an identification request signal, each electronic module ( 6 - 9 ) counts the number of identification request signals received by said electronic module, and, on an ad-hoc basis, orders the transmission of at least one counting signal incorporating the number m of said identification request signals received, and the central processing unit ( 11 ) is programmed, for each electronic module ( 6 - 9 ), to: calculate a ratio representative of the number of counted identification request signals received by said electronic module compared to the number of identification request signals actually transmitted by the transmitting antenna ( 12 - 14 ), and providing an indication of presence of said electronic module in the coverage area of the transmitting antenna ( 12 - 14 ), when the calculated ratio is greater than a predetermined threshold value.
