차량 안정성 제어 시스템을 위한 차량 모델의 안정성 영역 해석

This paper describes the design of a unified chassis control system and study of control input affects the vehicle dynamic stability. As the vehicle stability enhancement, unified chassis control system is developed by integration of a individual controller. Moreover original ability, these systems are used for vehicle behavior control by brake pressure control, superimposed steering, active damping control. Most of these systems composes that choice the reference parameter and control that minimize the error between reference and actual parameter, but effects of control input to vehicle stability is still unclear. This paper examine the parameter affects the vehicle stability with Lyapunov’s direct method and Topological method under several driving condition. Consequently, these control input guarantee the stability region, while satisfying all actuator constraints.
