Patent ID: 8296080

Claim:
A method of determining at least one main parameter representative of at least one interaction along a longitudinal direction between a tyre and ground, wherein a footprint area is defined between a first and a second longitudinal ends, comprising the following steps: identifying a first parameter representative of a radial deformation of said tyre; determining a first and a second values of said first parameter in a neighbourhood of the first longitudinal end of the footprint area and in a neighbourhood of the second longitudinal end of the footprint area, respectively, wherein the first value is associated with a first time instant and the second value is associated with a second time instant; calculating a linear combination of said first and second values, thereby obtaining a second parameter; determining a third parameter representative of an angular velocity of said tyre; calculating a ratio between said second and third parameters; and calculating said main parameter starting from said ratio, according to an algorithm, which main parameter is representative of at least one interaction along a longitudinal direction between said tyre and the ground.
