报告摘要:
Wireless vehicle-to-vehicle (V2V) communicationmay allow vehicles to obtain information beyond the line of sight which in turncan lead to improvements of safety, fuel economy and mobility in groundtransportation systems. In this talk we put forward the idea of connectedcruise control (CCC) that allow one to incorporate vehicles of different levelsof autonomy in the traffic flow ?including human-driven vehicles that may ormay be equipped with V2V devices. We construct models that take into accounthuman reaction time as well as communication delays arising due tointermittency and packet drops. Then we apply techniques form optimal controlof time delay systems to design controllers for CCC vehicles. Decomposing thearising Ricatti-type PDEs allows us to design the control gains sequentiallywith low computational cost. We demonstrate that the proposed controllers arecapable of avoiding congestion for even low penetration of CCC vehicles.
无线车辆交互(V2V)能够获取超视距信息，并有助于车辆安全性、燃油经济性以及地面交通系统机动性的提高。报告将介绍在包含配有V2V设备的有人驾驶车辆的情况下，与不同级别自主无人车协同下的网联巡航控制，然后提出由驾驶员反应时间、网络间歇现象和数据丢包引起的时滞模型建立方法，运用时滞最优控制方法，设计针对网联巡航车辆的控制器。同时介绍在较低计算成本下分解黎卡提微分方程组，从而设计控制器增益的方法。最后验证了该控制器即使在无人车比例较少的交通状况下同样能够有效避免交通堵塞。
