Cooperative adaptive cruise control (CACC) in leaderless scenario is addressed in this paper. The common idea in CACC is that a leader vehicle determines the steady state speed of the platoon without considering feedback from other vehicles. The main contribution of this paper is to propose a control strategy such that each vehicle in a leaderless platoon keeps a desired distance from its preceding vehicle, determined based on the constant time-gap spacing policy, and simultaneously all the vehicles reach consensus upon their speeds. Moreover, whereas each vehicle needs access to the information of some neighboring vehicles (via a communication network) to achieve speed consensus, we assume that it has access to the relative distance of just one possible preceding vehicle (using a radar/lidar). Simulation results illustrate the performance of the proposed control strategy.

Abstract
Cooperative adaptive cruise control (CACC) in leaderless scenario is addressed in this paper. The common idea in CACC is that a leader vehicle determines the steady state speed of the platoon without considering feedback from other vehicles. The main contribution of this paper is to propose a control strategy such that each vehicle in a leaderless platoon keeps a desired distance from its preceding vehicle, determined based on the constant time-gap spacing policy, and simultaneously all the vehicles reach consensus upon their speeds. Moreover, whereas each vehicle needs access to the information of some neighboring vehicles (via a communication network) to achieve speed consensus, we assume that it has access to the relative distance of just one possible preceding vehicle (using a radar/lidar). Simulation results illustrate the performance of the proposed control strategy.Pubblicazioni consigliate
