Abstract:
1. A method for locating the position of the wheels ( 2 ) of a vehicle ( 1 ), each wheel ( 2 ) being equipped with a sensor ( 3 ) capable of emitting a location signal and the vehicle ( 1 ) being equipped with a receiver ( 4 ) capable of receiving the location signals emitted by the sensors ( 4 ), said method comprising the following steps: determining a signature of the location signal emitted by the sensor ( storing in said receiver ( the receiver ( 4 ) being equipped with at least two antennas ( 5 a , 5 b ), called first and second antennas ( 5 a , 5 b ), the signature of the location signal emitted by the sensor ( 4 ) of each wheel ( 2 ) being determined from the strength difference between the strength of the signal received by the first antenna ( 5 a ) and the strength of the signal received by the second antenna ( 5 b ), said method being characterized in that the signature of the location signal emitted by the sensor ( 3 ) of a wheel ( 2 ) is determined by the following steps: measuring, at M measurement instants, the strength of the signal received by the first antenna ( determining, for each measurement instant, a value, called difference value, representative of the difference between the strength of the signal received by the first antenna ( performing a statistical analysis of the M difference values relative to N predetermined threshold values, N being an integer greater than or equal to 1, so as to define, for each of the N threshold values, a so-called statistical value representative of the number of difference values that are greater than or equal to said threshold value or representative of the number of difference values that are less than or equal to said threshold value.
