Abstract:
1. A method for localization of the lateral position of the wheels of a vehicle, said vehicle being equipped with a tire pressure monitoring system, and being equipped with an electronic central processing unit, said wheels each comprising: an electronic unit fixed onto a rim of radius R and comprising two accelerometers ( a microprocessor, said method comprising the following steps: I) measurement, per wheel rotation, at given intervals of time (Tmeasurement), of a number (N) of acceleration values by each of the accelerometers ( II) calculation by the microprocessor of a physical value (P) representative of the sign of the phase-shift angle between the two accelerometers, III) determination by the central processing unit of the vehicle of the lateral position of the wheel using the physical value (P) representative of the sign of the phase-shift angle, the method being characterized in that during the step I:
