  • This paper presents a comparison among three types of approaches to an ARC (Active Roll Control) with an AARB(Active Anti-Roll Bar) for a vehicle system. Lateral acceleration and road profile are considered as disturbance. The ARC is designed with an LQ SOF (Linear Quadratic Static Output Feedback) control, $H_{\infty}$ control and SMC (Sliding Mode Control). These approaches are compared in terms of rollover prevention and ride comfort. For comparison, Bode plot analysis based on linear model and frequency response analysis based on CarSim simulation are performed.

  • 차량 선회 시 조종안정성과 주행 승차감을 향상시키기 위하여 능동적으로 차체의 롤(roll)을 줄이기 위한 연구가 진행되고 있다. 전동식 능동 롤 제어(ARC) 시스템은 전후 스테빌라이저바 중앙에 위치한 전동 모터 방식의 구동기에 의해 차량의 차체 롤을 제어한다. 본 연구에서는 이러한 전동식 ARC 시스템의 제어 성능 및 차량 동역학적 특성을 평가하고 검증하기 위한 해석, 벤치 시험, 실차 시험의 3단계 절차와 방법을 제안하였다. ARC 제어로직의 성능 및 타당성 평가를 위한 Matlab/Simulink와 CarSim 간의 연동-해석 방법을 제안하였고, ARC 구동기 및 시스템의 성능을 평가하기 위한 벤치 시험 방법과 실차 시험 방법을 제안하였다.

  • This paper presents the design of an active roll control system for a ground vehicle and an experimental study using an devised electric-actuating roll control system. Based on a three degree of freedom linear vehicle model, the controller is designed using lateral acceleration and rollrate feedback. In order to investigate the feasibility of an active control system, experimental work is carried out using a hardware-in-the-loop (Hil) setup which has been constructed by the devised electric-actuating system and the full vehicle model including tire characteristics. The performance is evaluated by an experiment using the Hil setup with limited bandwidth. Finally, in order to enhance the control performance in the transient region, a hybrid control strategy is proposed and evaluated.

  • This paper describes an investigation into coordinated control of electronic stability control (ESC) and active roll control system (ARS). The coordinated control is suggested to improve the vehicle stability and agility features by yaw rate control. The proposed integrated chassis control algorithm consists of a supervisor, control algorithms, and a coordinator. The supervisor monitors the vehicle status and determines desired vehicle motions such as a desired yaw rate and desired roll motion based on control modes to improve vehicle stability. According to the corresponding the desired vehicle dynamics, the control algorithm calculated a desired yaw moment and desired roll moment, respectively. Based on the desired yaw moment and the desired roll moment, the coordinator determines the brake pressures and the ARC motor torques based on control strategies. Closed loop simulations with a driver-vehicle-controller system were conducted to investigate the performance of the proposed control strategy using CarSim vehicle dynamics software and the integrated controller coded using Matlab/Simulink.
