Abstract
A method for controlling a vehicle semi-active suspension system comprising at least one suspension, providing for: detecting vehicle dynamic quantities during the vehicle ride; using the detected dynamic quantities, determining an index of ride comfort and an index of roadholding; applying a weight factor to the index of ride comfort and to the index of roadholding and, based on a Sky Hook control model, determining a target damping force characteristics for the at least one suspension of the suspension system; controlling the at least one suspension to put the respective damping force characteristics in accordance with the calculated target damping force characteristics. The weight factor is calculated dynamically during the vehicle ride, by means of a fuzzy calculation on the detected vehicle dynamic quantities.
