Intelligent Vehicle Headway Distance Control System Design

Vehicle following for traffic safety has been an active area of research. The purpose of this paper is to design an intelligent vehicle headway distance control System. The proposed system uses relative speed, relative acceleration and spacing information from the preceding vehicles in order to choose the proper control action for smooth vehicle following and for maintaining a desired inter vehicle spacing. In this paper, a new sliding mode control approach based on tracking differentiator is proposed. Tracking-differentiator is designed to provide acceleration information as the control parameter. Theoretical analysis and computer simulation prove that the designed linear tracking-differentiator can supply the relative acceleration information for sliding mode control and sliding mode control based on tracking differentiator approach can effectively control intelligent vehicle headway distance.
