互联自动驾驶车辆多车道合并的分散最优控制

Decentralized Optimal Control in Multi-lane Merging for Connected and Automated Vehicles

Wei Xiao, Christos G. Cassandras, Calin Belta

摘要:

我们解决的问题,最佳控制连接和自动驾驶汽车(CAV)从两个多车道的道路到达并合并在多个点,其目标是共同最大限度地减少旅行时间和能源消耗的每个CAV受到速度依赖的安全约束,以及速度和加速度的限制。这个问题在两条单车道道路的先前工作中得到了解决。直接扩展到多车道的道路是有限的,所需的计算复杂性,以获得一个明确的最优控制解决方案。相反,我们提出了一个通用的框架,将多车道合并问题转化为一个分散的最优控制问题,为每个CAV在一个不太保守的方式。为了实现这一点,我们采用了联合最优控制和障碍函数的方法,有效地得到一个最优控制,为每个CAV的所有约束的保证满意。仿真例子包括比较所提出的框架的性能,由人类驾驶的车辆提供的基线与结果显示显着改善的时间和能源指标。

英文摘要:

We address the problem of optimally controlling Connected and Automated Vehicles (CAVs) arriving from two multi-lane roads and merging at multiple points where the objective is to jointly minimize the travel time and energy consumption of each CAV subject to speed-dependent safety constraints, as well as speed and acceleration constraints. This problem was solved in prior work for two single-lane roads. A direct extension to multi-lane roads is limited by the computational complexity required to obtain an explicit optimal control solution. Instead, we propose a general framework that converts a multi-lane merging problem into a decentralized optimal control problem for each CAV in a less-conservative way. To accomplish this, we employ a joint optimal control and barrier function method to efficiently get an optimal control for each CAV with guaranteed satisfaction of all constraints. Simulation examples are included to compare the performance of the proposed framework to a baseline provided by human-driven vehicles with results showing significant improvements in both time and energy metrics.
