Method and System for Determining the Potential Friction Between a Vehicle Tyre and a Rolling Surface

A method of determining the potential friction between a vehicle tyre and a rolling surface, said method comprising: detecting at least one signal (Sl) representative of a deformation of a portion of an inner surface (8) of a tyre (1); processing said at least one signal (Sl) for identifying at least one significant point on a curve representative of said signal (Sl); determining as a function of at least one coordinate of at least one of said significant points, a parameter (P) representative of the grip between said tyre (1) and rolling surface (5); determining as a function of said parameter (P), the potential friction ([mu]pot) between said tyre (1) and rolling surface (5). Also described is a system (100) for determining said potential friction ([mu]pot).
