고속 주행시 횡가속도 제어를 위한 MDPS 시스템 개발에 관한 연구 = The Research on the Lateral Acceleration Control for the MDPS System at High Speed Maneuver

다국어 초록 (Multilingual Abstract)

Power steering systems for automobiles are becoming more popular for reduceing steering efforts of the drivers, especially during parking lot maneuver. Though hydraulic power steering has widely usec for many years . the efficiency of hydraulic system is not high enough. The MDPS system can solve the problems associated with the hydraulic power steering system. In this study, the MDPS system with ball-screw mechanism is proposed by the bond graph modeling which has the motor, torque sensor, ball screw mechanism and so on. On the basis of the velocity boosting torque controller, the lateral acceleration controller is added. As well as the result, we can set constant frequency characteristics and enhance directional stability at high speed maneuver by controlling MDPS motor with proportional to steering wheel angular velocity.<br/>
