A scalable distributed model predictive control (MPC) strategy is proposed for nonlinear heterogeneous vehicular platoon systems with state and control constraints. Based on the unidirectional communication topology of Predecessor-Follower (PF), a scalable longitudinal discrete-time nonlinear model of the vehicle is established. Distributed optimization problem is established by defining the vehicle tracking performance index and the formation constraints of the vehicular platoon system. Based on the triplet of MPC and receding horizon, the recursive feasibility of the optimization problem is ensured. On this basis, sufficient conditions are obtained to ensure the stability and string stability of the scalable vehicular platoon system. Finally, simulation results verify the effectiveness of the proposed control strategy.
