The determination of the location of the wheel unit by the central processing unit (2) of the vehicle includes:
- applying, for each identifier and to the number of signals received by the central processing unit, a transfer function specific to each antenna;calculating a number by multiplying the transfer function by one another such that they represent the specific front right, front left, rear right and rear left positions on the vehicle (1); andlocating the wheel units by determining, for each specific position represented by the transfer functions, the identifier corresponding to the highest number P.
