Simulation tools and evaluation criteria for steering wheel feel improvement of an electric power steering system

摘要

Centro Ricerche Fiat in collaboration with Fiat Auto vehicle test department has developed a numerical- experimental procedure in order to support on-road development and fine tuning of a new car with electric power steering. The integration of an electric power steering model, given by the supplier, in a full-vehicle model, in order to evaluate steering feel objective quality indices, has allowed to improve vehicle performance in term of steering feel and reduce on-road development time.
