Abstract

In this paper, a novel type of an integrated controller is designed for vehicles equipped with active classis systems to improve vehicle stability, handling, and ride comfort. The hybrid fuzzy logic controller consists of a fuzzy logic controller, a skyhook controller, an attitude controller, and a roll moment distribution controller, and these controllers are used with a proper combination which is determined by the integrated control logic based on driving conditions of a vehicle. It is shown by simulations using MATRIXx/SYSTEMBBUILD software that ride comfort, handling, and active safety are improved for a 16 degree-of-freedom vehicle dynamic model.

본 논문에서는 능동형 샤시 시스템이 정착된 차량의 안정성(Stability), 조종성(Handling) 및 승차감(Ridecomfort)을 향상시키기 위한 새로운 통합제어기를 설계한다. 하이브리드 퍼지논리 제어기는 퍼지논리 제어기, 스카이 훅 제어기, 자세 제어기 및 롤 모멘트 분포 제어기로 이루어지며, 차량의 주행상태에 기초한 통합제어로직을 이용하여 위와 같은 제어기들을 적절히 결합시켜 사용한다. 또한 MATRIXx/SYSTEMBBUILD 소프트웨어를 이용하여 16자유도 차량모델에 대하여 시뮬레이션을 수행함으로써 차량의 승차감, 조종성 및 능동적 안전도가 향상됨을 확인한다.
