Patent ID: 7893820

Claim:
A method of transmitting an electromagnetic identification request signal, generated by means of an antenna ( 11 - 14 ) connected to a central unit ( 15 ) mounted on a vehicle ( 1 ), to an electronic housing ( 6 - 9 ) mounted on a wheel ( 2 - 5 ) of said vehicle, this transmission method consisting in successively transmitting, after starting of the vehicle ( 1 ), a plurality of identical identification request signals (S 1 . . . , Si, Si+1, . . . ), and said transmission method being characterized in that it consists, after each transmission at an instant Ti of a signal Si: in measuring the speed of travel V of the vehicle ( 1 ) and in calculating the time Tr of a complete rotation of the wheel ( 2 - 5 ) for said speed V, and in triggering the following signal Si+1 at an instant Ti+1 such that Ti+1=Ti+nTr+Tθ with n integer ≧1 and 0<Tθ<Tr.
