This paper proposed model predictive control intelligent optimization strategies based on vehicle platooning for hybrid electric vehicles to deal with energy management problems without consideration of vehicle platooning in conventional control strategies. The reduced order system model was developed. The model predictive control problem was solved using continuation/generalized minimum residual method. The simulation was conducted using computers. The results showed that the proposed model is effective, and the proposed model predictive control method can improve fuel economy significantly and can be implemented in real-time
