Abstract: This paper presents the design of a longitudinal control system for a platoon of vehicles. The synthesis of an automatic vehicle following system is an important aspect of an automated highway system design. The main objectives of the control of a platoon of vehicles are the increment of the exploitation of the road capacity and the improvement of passengers' safety and comfort. The proposed control system is designed relying on a non-linear vehicle model. The chosen control methodology is second-order sliding mode control. This choice is motivated by the well-known robustness features of the sliding mode control approach, which are particularly appropriate dealing with the automotive context. Moreover, the proposed approach produces a considerable reduction of the chattering phenomenon, which can determine undesired mechanical wear in the actuators. The individual vehicle stability and platoon stability are guaranteed by the proposed control system. This latter is tested in simulation considering a platoon of three vehicles in a stop-and-go traffic situation.
