DEVELOPMENT OF AN ELECTRIC ACTIVE ROLLCONTROL (ARC) ALGORITHM FOR A SUV
전광기,H. HWANG,S. CHOI,J. KIM,K. JANG,이경수 한국자동차공학회 2012 International journal of automotive technology Vol.13 No.2
Cornering maneuvers with reduced body roll and without loss in comfort are leading requirements for car manufacturers. An electric active roll control (ARC) system controls body roll angle with motor-driven actuators installed in the centers of the front and rear stabilizer bars. A vehicle analysis model developed using a CarSim S/W was validated using vehicle test data. Two ARC algorithms for a sports utility vehicle (SUV) were designed using a sliding-mode control algorithm based on a nonlinear roll model and an estimated lateral acceleration based on a linearized roll model. Co-simulation with the Matlab simulink controller model and the CarSim vehicle model were conducted to evaluate the performance of two ARC control algorithms. To validate the ARC performance in a real vehicle, vehicle tests were conducted at KATECH proving ground using a small SUV equipped with two ARC actuators, upper and lower controllers and a few subsystems. From the simulation and vehicle validation test results, the proposed ARC control algorithm for the developed ARC actuator prototypes improves the vehicle’s dynamic performance.

This study presents a few fail-safe control strategies based on reliability evaluation scenarios for the electronic brake systems of green cars in several critical cases. CarSim and MATLAB Simulink were used to develop the FCEV model with regenerative braking involving EWBs and EMBs. The proposed reliability evaluation scenarios were simulated, and a few fail-safe control algorithms were verified using the proposed reliability evaluation scenarios with the developed FCEV simulation model. The reliability evaluation scenarios were developed using a combination of driving modes and FMEA results for these electronic brake systems.

The demand of the green car such as hybrid electric vehicle, fuel cell electric vehicle and pure electric eehicle has been rising dramatically. The key part is the regenerative braking system in the energy saving technology of gren car. And electronic braking system has been developed along with the advance of the electronic control technology. The reliability about the electronic braking system is very important because it is concerned with the safety of vehicle. But the regulation of the reliability assessment test for the regenerative braking and electronic braking system is not sufficient enough. In this paper, FCEV with regenerative braking system and electronic braking system(EWB, EMB) has been modeled to develop the reliability assessment technology. With a lot of ABS brake regulations and FMEA results about the regenerative braking system and electronic braking system, the reliability assessment scenarios have been developed. This scenarios have been applied to the performance simulation and it is shown effective to evaluate the reliability of green car regenerative braking with electronic braking system.

Cornering maneuvers with reduced body roll and without losses in comfort are heading the wish list of car manufacturers. In addition to this, driving safety can be improved considerably with Active Roll Control(ARC) systems. The ARC system can control body roll angle by using DC motor actuators installed in the center of front and rear stabilizer bars. Full vehicle analysis models have been developed using an ADAMS/Car and a CarSim S/W, and these vehicle models have been validated using vehicle test. The ARC controller has been evaluated with two kinds of control algorithm. One has been designed using a slide mode control law based on a roll model and the other has been designed using a estimated lateral acceleration and target roll angle map data. Co-simulations have been conducted by using the Matlab simulink and the validated CarSim vehicle model to evaluate the performance of the ARC control algorithms. From the simulation results, it is shown that the proposed ARC control system can provide with improved vehicle comfort.
