Platooning technology is becoming a future task which suggests as a way of reducing carbon dioxid e emissions and realizing safe driving at a high speed velocity. This paper describes a few control methods f or vehicle-platooning. The conventional control method improved fuel consumption by shortening the distance between vehicles. By contrast, the method we proposed improves it by controlling the velocity at the time of acceleration gently. The velocity is controlled by generating the desired value of inter-vehicular distance corres ponding to the leading vehicle velocity. Another method which is planned to realize a highly efficient arterial traffic distribution system includes reducing aerodynamic drag by minimizing the distance between vehicles to allow drafting. In this paper, the two degrees-of-freedom control system is applied for it. These proposed met hods were evaluated by simulation and some experiments.
