Steer-by-Wire 시스템을 위한 조향감 향상

Abstract

This paper is about steering system of Steer-by-Wire(SBW). As a SBW system is applied in order to improve steering feel and maneuverability, the controller should have two purposes. One is controlling steering wheel for the driver's steering feel and the other is controlling the front wheel system for vehicle stability. This study focuses on steering wheel system. The column is reduced in the SBW steering wheel system. Therefore it need artificial steering feel. This is the study for an objective evaluation method with steering angle, steering torque to quantify steering feel of SBW system. Based on this method, the affect two different torque map performance was simulated and compared each other.
