在本文中，提出了基于加速的连接巡航控制（CCC）来增加道路交通交通机动性。 CCC旨在使用通过无线车辆到车辆（V2V）通信从多个车辆接收到的加速信号。我们考虑由人类驱动和CCC车辆组成的异质排中的各种连通性结构。我们表明，将一些CCC车辆插入流动中，并延迟了一些CCC车辆，可以稳定静止的不稳定车辆的车辆。利用临时连通性的灵活性，CCC可以在各种交通情况下应用。此外，使用加速反馈以选择性的方式，CCC提供了稳健的性能，并且对于大型连接车辆系统仍然可扩展。我们的结论通过非线性级别的模拟来验证。 （c）2014 Elsevier Ltd.保留所有权利。
In this paper, acceleration-based connected cruise control (CCC) is proposed to increase roadway traffic mobility. CCC is designed to be able to use acceleration signals received from multiple vehicles ahead through wireless vehicle-to-vehicle (V2V) communication. We consider various connectivity structures in heterogeneous platoons comprised of human-driven and CCC vehicles. We show that inserting a few CCC vehicles with appropriately designed gains and delays into the flow, one can stabilize otherwise string unstable vehicle platoons. Exploiting the flexibility of ad-hoc connectivity, CCC can be applied in a large variety of traffic scenarios. Moreover, using acceleration feedback in a selective manner, CCC provides robust performance and remains scalable for large systems of connected vehicles. Our conclusions are verified by simulations at the nonlinear level. (C) 2014 Elsevier Ltd. All rights reserved.
