Method for determining the position of a radial acceleration sensor of a wheel of a motor vehicle

A method for determining a position of a radial acceleration sensor of a wheel of a motor vehicle, said method comprising:

• an acquisition step of acquisition, by the radial acceleration sensor, of signals Si, each signal Si being acquired during predetermined time windows Wi when the vehicle is in motion, the windows Wi being different from one another,
• a detection step of detecting, for each time window Wi, at least three local extrema of the signal Si which are respectively associated with phase values and with detection instants,
• a determination step of determining, for each time window Wi, a frequency Fi of a rotation of the wheel of the vehicle as a function of the phase values and of the detection instants for the local extrema detected in said time window Wi,
• a filtering step of low-pass filtering of the signals Si, so as to obtain, for each time window Wi, a filtered value Zi associated with the frequency Fi, and
• a determination step of determining a radial distance Rc between the radial acceleration sensor and an axis of rotation of the wheel as a function of the filtered values Zi and of the frequencies Fi.
