2륜 독립조향 Steer-by-Wire 시스템의 제어기 개발

Abstract

In this study, the controller of a SBW (Steer-by-Wire) system was developed. As a SBW system is applied in order to improve steering feel and maneuverability, the controller should have two aims. One is controlling steering wheel for the driver's steering feel and the other is controlling the front wheel steering linkage for vehicle stability. In order to the tie-rod actuating SBW controller analysis, 6-bar linkage kinematics was investigated. The controller of the tie-rod actuating SBW was used the Ackerman Geometry for improving the vehicle stability. Verification simulation and performance simulation are showed that the SBW controller was available in this study.
