最近，车辆编队作为解决车辆数量爆炸的有前途的解决方案之一引起了广泛关注。通过通信网络在车辆之间交换信息，车辆编队可以显着提高交通安全和效率。在本文中，我们开发了一种队列通信和控制的联合系统设计，以减少连续车辆的位置误差并提高队列安全性。通过排长和随从分别进行信息发布，提高了排长信息发布的成功概率。为了扩大排长的通信范围和排规模，我们建议使用中继来转发排长的消息。此外，提出了一种基于自适应分布式模型预测控制（DMPC）的控制器，它可以根据排状态和动态信息源调整其控制参数。仿真结果不仅在位置误差方面验证了所提出的系统设计，而且还表明我们的方案在车辆故障情况下表现良好，可以避免碰撞并提高队列安全性。
Recently, vehicle platooning has attracted a lot of attention as one of the promising solutions to the explosion of vehicle numbers. By exchanging information among vehicles through communication networks, vehicle platooning can significantly improve traffic safety and efficiency. In this paper, we develop a joint systematic design of platoon communication and control to reduce position errors of consecutive vehicles and to improve platoon safety. Through separate information dissemination of the platoon leader and followers, we improve the success probability of the platoon leader's information dissemination. To extend the communication range of the platoon leader and also the platoon scale, we propose to use relays to forward the platoon leader's messages. Further, an adaptive distributed model predictive control (DMPC) based controller is presented, which can adjust its control parameters according to platoon state and dynamic information sources. Simulation results not only verify the proposed systematic design in terms of position errors, but also show that our scheme performs well in vehicle failure cases where collisions can be avoided and platoon safety improved.
