Abstract: Method for determining the angular position of an electronic module fixed to the inner face of the tread of a tire fitted to a wheel of a vehicle. A sensor for measuring the radial acceleration of the wheel is integrated into the electronic module, measuring at least one measurement of the radial acceleration for determining the value of the period of revolution of the wheel, and detecting a variation of the radial acceleration representative of a position of the electronic module contacting the ground, the position of the electronic module in which the variation is detected is assigned the origin function of a frame of reference defined by the origin and a reference unit formed by an angular sector whose length is substantially shorter than the mean length of the footprint of the grounded tire, and the angular positions of the electronic module in the frame of reference are determined.
