F2008-SC-023 A Study of Steering System Model for Steering Feel’s Improvement of Steer-by-Wire System

ABSTRACT- Steer-By-Wire(SBW) system is the one of the advanced technologies that will be applied to steering system for the next generation's vehicles. It removes mechanical linkages between steering wheel and front wheels. As a result, SBW enhances controllability of vehicle dynamic characteristic and safety of car crash, and simplifies vehicle design process. The main purpose of this study is to focus on steering system model for steering feel improvement. It is very important to be developed for a driver to adjust the steering feel, as if hydraulic steering system conveys. In this study, the steering system model is designed by Matlab/Simulink and LabVIEW, and verified by real-time simulation using Carsim RT and LabVIEW RT
