차량 통합제어 시스템의 설계환경 개발 및 응용

A systematic design environment for integrated control of chassis system is developed and its effectiveness is demonstrated in this paper. 4WSS based on yaw rate feedback and a hydropneumatic ASS based on PID control are developed first. A decision logic to identify present driving conditions is also developed using sensed vehicle signals such as vertical acceleration. steering angle, lateral acceleration, etc. An algorithm that adjusts control parameters of the 4WSS and the ASS automatically according to driving conditions is proposed. MATRIXx/SYSTEMBULLD software is used to illustrate that vehicle stability, maneuverability, and ride comfort are improved by the proposed integrated control method.
