Abstract
A method of calculating forces acting on the footprint area of a tire, the tire being mounted on a wheel in turn mounted on a hub for engagement with a vehicle, the tire being moved along a longitudinal direction substantially parallel to the ground, includes the following steps: detecting a first angular position of the footprint area; detecting a second angular position of a reference point substantially integral with the hub; comparing the first and second angular positions with each other to determine a phase displacement between the reference point and footprint area; determining a parameter representing an angular velocity of the wheel; calculating at least one longitudinal force in the footprint function of at least the phase displacement and the parameter. Also described is an apparatus for calculating the forces.
