Abstract
This paper considers the problem of controlling a convoy of autonomous vehicles to be deployed on automated highways. The individual behavior of an autonomous vehicle as an intelligent self-interested decision-maker can be analyzed under a non-cooperative differential game model of the convoy. The receding horizon Nash equilibrium of the linear-quadratic differential game provides a distributed state-feedback control strategy for the convoy. This approach suffers a fundamental issue that neither the existence nor the uniqueness of a Nash equilibrium is guaranteed, so the convoy control. We present a relative dynamics based model of the convoy that carries all the features of the individual dynamics based game model. We show that the relative dynamics model guarantees the existence of the convoy control as well as the asymptotic stability of the closed-loop system. Simulations illustrate the effectiveness of the presented convoy control scheme.
