Method for locating the position of wheels which are fitted with an electronic unit incorporating means of measuring an operating parameter of said wheel
First Claim
1. A method for locating the position of the wheels (5-8) of a vehicle (V) comprising:
- r wheels (5-8), each fitted with an electronic unit (1-4) incorporating means (9), called mobile means, for measuring a predetermined operating parameter of said wheel, called the location parameter, and a transmitter (10) intended to transmit signals including data representative of the measured values of said location parameter and an identification code of said electronic unit,r means (13-16), called fixed means, assigned to each wheel position (5-8) and mounted on the vehicle (V) for measuring the location parameter of said wheel,and a central unit (11) mounted on the vehicle (V) and provided with means (12) for receiving, on the one hand, signals from the electronic units (1-4), and, on the other hand, data representative of the values measured by the fixed measurement means (13-16),said location method consisting in studying the correlation between the values measured by the fixed measurement means (13-16) and those measured by the mobile measurement means (9), in order to assign a wheel position (5-8) to each electronic unit (1-4), this location method being characterized in that;
for each electronic unit (1-4), the data representative of the values measured by the mobile measurement means (9) incorporated in said electronic unit are compared with those measured by each of the r fixed measurement means (13-16), and the correlation between said data is studied in order to establish a correspondence between an electronic unit (1-4) and a wheel position (5-8),for each wheel position (5-8), the data representative of the values measured by the fixed measurement means (13-16) assigned to said wheel position are compared with those measured by each of the r mobile measurement means (9) incorporated in the electronic units (1-4), and the correlation between said data is studied in order to establish a correspondence between a wheel position (5-8) and an electronic unit (1-4), anda wheel position (5-8) is assigned to an electronic unit (1-4) when there is a mutual correspondence between said wheel position and said electronic unit.

Abstract
The invention relates to a method for locating the position of wheels (5-8) of a vehicle (V) comprising, mounted on each wheel, an electronic unit (1-4) incorporating measurement means (9) for measuring a predetermined operating parameter for said wheel, referred to as a location parameter and, assigned to each wheel position and mounted on the vehicle (V), fixed means (13-16) for measuring the location parameter for said wheel. This location method consists, firstly, for each electronic unit (1-4), in comparing the values measured by the mobile measurement means (9) incorporated into said electronic unit with those measured by each of the fixed measurement means (13-16), secondly, for each wheel position, comparing the values measured by the fixed measurement means (13-16) assigned to said wheel position with those measured by each of the mobile measurement means (9), then assigning a wheel position to an electronic unit (1-4) when these correspond with one another.
