좌우독립형 Steer-by-Wire 시스템을 이용한 능동조향 제어알고리즘 개발

Abstract

This paper is about steering system of Steer-by-Wire(SBW). The SBW system consists of two parts. One is Steering wheel system and the other is front wheel system. There is no mechanical system between the steering wheel system and front wheel system. Steering wheel system applies the appropriate steering feel to the driver. Therefore it can be tuned easier than conventional system. Front wheel system is Tie-rod actuating type which has two independent actuating. We need the algorithm that operates the front wheel system and improves the stability and the maneuverability. The algorithm in this paper is based on Ackerman constraint. The algorithm is simulated by CarSim which has 27 DOF.
