Method of transmitting an electromagnetic identification request signal to an electronic housing mounted on a wheel of a vehicle
First Claim
1. 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 (S1 . . . , 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

Abstract
Method of transmitting an electromagnetic identification request signal, generated by 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 the vehicle. This transmission method includes successively transmitting, after starting of the vehicle (1), a plurality of identical identification request signals (S1 . . . , Si, Si+1, . . . ), and wherein, after each transmission at an instant Ti of a signal Si, the speed of travel V of the vehicle (1) is measured, the time Tr of a complete rotation of the wheel (2-5) is calculated for the speed V, and the following signal Si+1 is triggered at an instant Ti+1 such that: Ti+1=Ti+nTr+Tθ with n integer ≧1 and 0<Tθ<Tr.
