능동 현가 제어시스템을 위한 차량 롤 모델 개발

다국어 초록 (Multilingual Abstract)

This paper presents a vehicle roll model for a vehicle equipped with an active and/or semi-active suspension control system, such as ARS(Active Roll System) and ECS(Electronic Control Suspension). First, the second-order roll dynamics equation with lateral acceleration sensor input is derived, and, then, it is reduced to the first-order system upon consideration of frequency response characteristics. Roll moment generated by ARS is applied to the roll model as additional moment input, and damper characteristic variation by ECS is reflected on the time constant of the first-order roll model. The proposed roll model is verified by experimental vehicle tests and CARSIM simulation. Results show relative improvement in estimation accuracy, compared to previous approaches.
