Abstract
A method for detecting and estimating an angle of rotation on itself, about a mounting axis, of a wheel unit with an acceleration sensor, the wheel unit being associated with a tire mounted on a rim, forming a wheel, the sensor detecting a gravitational force during the rotation of the wheel, forming a sinusoid. The wheel unit is mounted on the wheel with the acceleration sensor directly or indirectly inclined with respect to a plane tangential to the rim. The angle of rotation on itself of said wheel unit and therefore of the acceleration sensor at a given instant is estimated by comparing at least one parameter of the sinusoids that are obtained for the wheel unit in an initial mounting position on the wheel and in its position at this given instant, respectively.
