摘要:

自动驾驶车辆是智能交通系统的重要组成部分,自动驾驶应用需要在采集大量交通数据的基础上,实施信息处理与控制决策。由于交通信息的时空属性,即信息只在某一时间段内或某一区域内有效,独立车辆有限的信息感知范围严重制约了自动驾驶应用数据采集的有效性。车联多智能体协同决策为上述问题提供了可行的解决思路,提出了一种多维度感知信息融合机制,提升车载信息融合对自动驾驶任务的增益。在此基础上,设计了面向自动驾驶应用的智能分布式的决策算法,在最大化信息融合对自动驾驶任务增益的同时,最大化路网交通车流量,并满足自动驾驶车辆的成本和资源约束。仿真结果验证了所提算法的收敛性和实用性。

Abstract:

Autonomous vehicles play an important part in intelligent transportation systems.In these vehicles,driving control decision is obtained based on the collection of massive traffic states and intensive information processing.However,the spatial-temporal characteristics of the traffic states and the constrained environmental perception range of an individual vehicle seriously undermine the effectiveness of the state collection.Multi-agent driven collaborative decision provides a potential approach to address the problem.A multi-dimensional information fusion mechanism was proposed,which improved the gain of vehicular information fusion for autonomous driving tasks.Moreover,an intelligent distributed decision algorithm was designed for autonomous driving applications,which maximized the road traffic flow while maximizing the gain of information fusion on the autonomous driving mission under vehicular cost and resource constraints.Numerical results demonstrate the convergence and practicability of the proposed algorithm.

Key words: autonomous driving, multi-agent, information fusion, mobile edge service
