1. A method for determining a pivoting angle (α

  • ) of a wheel unit (12) mounted onto a snap-in inflation valve (10), said valve being placed on a wheel of a motor vehicle, said method including the following phases;

    Phase 1;

    observation of a curve C representing the effect of gravity on the radial acceleration Ames of a wheel of the vehicle on a sensing axis Y′

    which is related to the wheel unit and is not parallel to the axis of rotation of the wheel, by spectrum analysis of the gravity curve at a sampling frequency Fs greater than an assumed rotation speed ω

    of the wheel,Phase 2;

    deduction of an actual rotation speed ω

    of the wheel, andPhase 3;

    determination of the pivoting angle α

    according to the formula
