Abstract
A system and a method for estimating the International Roughness Index (IRI) of a road or road segment includes determining the IRI as a function of physical quantities relating to the motion of a vehicle, for instance the vertical accelerations, and to the vehicle itself, for instance the damping and stiffness coefficients of the suspensions of the vehicle and the tires mounted on the vehicle.
