A simulator environment was carried out in order to test the control algorithm performance on dynamic behaviour of system model. A model has been designed to study environment constraints and to simulate a platoon of three vehicles with automatic guidance functions. Platoon control technics were applied to control longitudinal dynamic of vehicles using inside sensor measurements (laser, gyros and accelerometers). The lateral dynamic of vehicles was independently controlled by outside sensor measurements (transponders along the vehicle’s path). These were used to get an error signal for the feedback controller and as a preview signal concerning the desires trajectory used for the feed forward compensator.
