ESC, AFS와 AGCS를 이용한 샤시 통합제어시스템 설계

The active chassis control systems have been developed with vehicle electronic technology by achieving operating convenience and guaranteeing the stability of the vehicle. However, each controller has been optimized to meet its object according as developing each controller. In this paper, two integrated control logics - one that integrates Electronic Stability Control and Active Geometry Control Suspension and the other that integrates Electronic Stability Control and Active Front Steering - have been developed. The main control target of both logics is vehicle dynamics control under critical situations. The two logics were tested under various driving conditions in a reliable simulation environment and their synergetic effects were investigated. The results indicate that the proposed logics can yield better vehicle performance than the cases when the individual chassis control modules work without any integration scheme.
