A method and system for estimating the load acting on a tire, wherein data are obtained, representative of the deformation undergone by the tire on a rolling surface. The data obtained are processed in order to obtain a first quantity representative of the deformation extent within a first deformation region substantially corresponding to the footprint between the tire and the rolling surface and a second quantity, different from the first quantity, representative of the deformation extent in a second deformation region, the second region including the first deformation region and having a circumferential extension greater than the circumferential extension of the first deformation region, the second quantity being obtained starting from at least a part of the obtained data, which corresponds to a portion of the second deformation region which is external to the footprint. The load is estimated based on the first quantity and the second quantity thus obtained.

Method and system for estimating the load acting on a tire

A method and system for estimating the inflation pressure of a tire in which data representative of the deformation undergone by the tire on a rolling surface are obtained. The obtained data are processed so as to obtain a first quantity representative of the extent of the deformation within a first deformation region substantially corresponding to the footprint between the tire and the rolling surface and a second quantity, different from the first quantity, representing the extent of the deformation in a second deformation region, said second region including the first deformation region and having a circumferential extension greater than the circumferential extension of the first deformation region, the second quantity being obtained starting from at least a part of the obtained data, which corresponds to a portion of said second deformation region that is external to the footprint. The pressure is estimated based on the first quantity and the second quantity thus obtained.

Method and system for estimating the inflation pressure of a tire

A method and system for determining the potential friction between a tire and a rolling surface wherein: the tire is rotated on the rolling surface so as to subject a crown portion of the tire to an acceleration radial component; data are obtained which are representative of the acceleration radial component to which the crown portion is subjected during at least one tire revolution; starting from the data, data are selected which are representative of at least one transition region of the acceleration radial component; the selected data are processed so as to obtain information correlated with the steepness of transition of the at least one transition region; and the potential friction is estimated on the basis of the information correlated with the steepness of transition.
