Autonomous intelligent cruise control using front and back information fortight vehicle following maneuvers

During manual driving, most human drivers often use information about the s peed and position of the preceding and following vehicles in order to adjus t the position and speed of their vehicles. The purpose of this paper is to design an autonomous intelligent cruise control (AICC) which mimics this h uman driving behavior, The proposed AICC law uses relative speed and spacin g information from the preceding and following vehicles in order to choose the proper control action for smooth vehicle following and for maintaining a desired intervehicle spacing specified by the driver. The vehicle stabili ty and platoon stability (in the case of multiple vehicles) in both directi ons (backward and forward) are guaranteed by the proposed AICC law. Further more, platoon stability is guaranteed for a speed-dependent desired spacing (time headway approach) as well as for a constant desired spacing at all s peeds.
