Abstract:
1. Process for location using locating sensors ( 100 , 101 , 110 , 111 ) each mounted on a vehicle wheel ( 4 ), each sensor being provided with an emitter and the vehicle ( 2 ) being provided with a corresponding receiver ( 6 ) adapted to receive the signals emitted by each sensor ( 100 , 101 , 110 , 111 ), characterized in that the receiver ( 6 ) is provided with two separate antennas ( 12 , 14 ), separated from each other and disposed such that neither antenna is located substantially equidistantly from the sensors ( 100 , 101 , 110 , 111 ), the two antennas ( 12 , 14 ) being located on the same side of the vehicle, and in that the location of the sensors ( 100 , 101 , 110 , 111 ) is carried out by analyzing the field power received by the receiver ( 6 ) by means of each antenna ( 12 , 14 ) for each sensor, the power of the field received by one antenna being the greater, the nearer to the antenna is the sensor that emitted the corresponding signal, for a vehicle having four wheels ( a) analysis of the power of the signals received by the two antennas ( b) one antenna being inactivated and the other being activated, analysis of the power of the signals received by the two sensors ( c) one antenna being inactivated and the other being activated, analysis of the power of the signals received from the two sensors (
