Steer-by-Wire 시스템 제어 알고리즘 개발

Abstract

This paper presents a control algorithm for Steer-by-Wire (SBW) system. SBW system consists of two parts. One is steering wheel system and the other is front wheel system. Front wheel system is the tie-rod actuating type. The control algorithm of the steering system used the torque map to generate reactive torque. In tie-rod actuating type, there are two motors, independent actuating. In developing the tie rod actuating type SD W system, the Ackerman constraint was used for control the two motors to improve stability and maneuverability. The validity was verified by full car simulation.
