In order to evaluate the vehicle steering feels of the Electric Power Steering(EPS) system effectively,the maneuver ability of steering,the return ability of steering,the ISO lane change capability,and the on-center steering capability were adopted as test factors.On the basis of group multicriteria decision making and fuzzy Analytical Hierarchy Process(AHP) method,the EPS hierarchic fuzzy evaluation model was established,and a simplified scale method was adopted to generate the judgment matrices meeting the consistency checking.Fuzzy intervals of EPS schemes were ranked with total weighted values and the optimal alternative could be selected.An example was given,under this approach,show that the decision making process was a systematic and practical method for EPS schemes selection.
