Abstract:
1. A method for determining potential friction between a tyre and a rolling surface, a footprint being defined between said tyre and said rolling surface, comprising: rotating the tyre on the rolling surface so as to subject a crown portion of the tyre to an acceleration radial component, according to a radial direction of the tyre; obtaining data representative of the acceleration radial component to which said crown portion is subjected during at least one tyre revolution, said acceleration radial component comprising two regions R starting from said data, selecting data representative of at least one transition region of said acceleration radial component, said at least one transition region comprising at least one portion of one of said regions R processing the selected data so as to obtain information correlated with the steepness of transition of said at least one transition region; and estimating the potential friction on the basis of said information correlated with the steepness of transition.
