Study on active steering control of vehicle for safe driving in highway with GPS information

In recent days, vehicles have become equipped with electric system that assist and help drivers driving safe in highway. Lane Departure Warning and Lane Keeping Assistant System are one of those safe system. Sudden and inattentive lateral motion of vehicle due to drivers´ fatigue, illness, inattention, and drowsiness are major causes of accidents in highway. In order to prevent and minimize any possible accidents due to lateral motion of vehicle, active steering control system is designed and simulated in this study. Activation and warning areas are defined for the control system with respect to the location of vehicle and parameters for vehicle dynamics. The current location of vehicle is obtained by Differential Global Positioning System (DGPS) and it can detect DGPS-based lanes then determine whether activates or not.
