基于先进车辆控制和通信技术的互联自动驾驶车辆（CAV）可以提高交通吞吐量、安全性和能源效率。以往的CAV控制研究主要集中在CAV编队的不稳定性和稳定性方面，但这些分析不能揭示CAV编队的阻尼振荡特性，而阻尼振荡特性对于提高CAV编队在各种连续扰动下的可靠性至关重要。为此，本研究旨在通过利用编队的非受迫振荡，即，阻尼特性受机械振动理论的启发，所提出的方法被应用到一个CAV排的线性车辆跟随控制制定为Helly的模型和跟随通信拓扑结构。该方法被应用到CAV排的线性跟驰控制制定为Helly的模型和跟随通信拓扑。数值分析结果表明，与CAV编队共振频率相同的周期扰动将放大振荡，导致最大振荡流量。我们的分析突出了防止队列振荡共振，以确保CAV编队的可靠性的重要性。
Connected automated vehicles (CAVs), built upon advanced vehicle control and communication technology, can improve traffic throughput, safety, and energy efficiency. Previous studies on CAVs control focus on instability and stability properties of CAV platoons; however, these analyses cannot reveal the damping platoon oscillation characteristics, which are important for enhancing CAV platoon reliability against variant continuous perturbations. To this end, this research seeks to characterize the damping oscillations of CAVs through exploiting the platoon's unforced oscillatory,i.e.,dampingbehavior. Inspired by the mechanical vibration theory, the proposed approach is applied to a CAV platoon with linear car-following control formulated as Helly's model and the predecessor-following communication topology. The proposed approach is applied to a CAV platoon with the linear car-following control formulated as Helly's model and the predecessor-following communication topology. Numerical analysis results show that a periodic perturbation with the resonance frequency of the CAV platoon will amplify the oscillation and lead to the severest oscillatory traffic. Our analysis highlights the importance of preventing platoon oscillations from resonance in ensuring CAV platooning reliability.
