<p>The invention relates to a method for transmitting an identification request electromagnetic signal generated by means of an antenna (11 14) connected to a central unit (15) mounted on a vehicle (1), to an electronic unit (6-9) mounted on a wheel (2-5) of the vehicle. This transmission method consists of successively emitting, after starting the vehicle (1), a number of identical identification request signals (S1..., Si, Si+1,...) and is characterized in that, after each emission at an time Ti of a signal Si, the speed of displacement V of the vehicle (1) is measured, the time Tr of a complete rotation of the wheel (2-5) for this speed V is calculated, and the following signal Si+1 is activated at time Ti+1 such that Ti+1 = Ti + nTr + T? with n being an integer > 1 and 0 < T? < Tr.</p> |
