论文摘要
车辆到车辆（V2V）通信具有改善交通系统性能的巨大潜力。大多数现有的连接和自动驾驶汽车（CAV）的工作都集中在适应下游交通状况上，忽略了骑士行为对上游交通流量的影响。在本文中，我们介绍了一个领先的巡航控制（LCC）的概念，该概念保留了基本的跟踪操作，并明确考虑了CAV行动对背后车辆的影响。我们首先提出了LCC的详细建模过程。然后，严格的可控性分析验证了利用骑士作为领导者积极领导其以下车辆运动的可行性。此外，在充分使用V2V连接性的情况下，从头到尾转移功能是为LCC得出的。数值研究证实了LCC增强骑士在抑制交通不稳定和平滑交通流量方面的能力的潜力。
Vehicle-to-vehicle (V2V) communications have a great potential to improve traffic system performance. Most existing work of connected and autonomous vehicles (CAVs) focused on adaptation to downstream traffic conditions, neglecting the impact of CAVs' behaviors on upstream traffic flow. In this paper, we introduce a notion of Leading Cruise Control (LCC) that retains the basic car-following operation and explicitly considers the influence of the CAV's actions on the vehicles behind. We first present a detailed modeling process for LCC. Then, rigorous controllability analysis verifies the feasibility of exploiting the CAV as a leader to actively lead the motion of its following vehicles. Besides, the head-to-tail transfer function is derived for LCC under adequate employment of V2V connectivity. Numerical studies confirm the potential of LCC to strengthen the capability of CAVs in suppressing traffic instabilities and smoothing traffic flow.
