論文概要について

協調型自動運転の実現に向けて、高精度3次元地図に動的情報を重畳したダイナミックマップが注目されています。膨大な車両データを集約し、リアルタイムに処理を行う必要があり、ダイナミックマップが構築されているサーバと車両は、より効率的に通信を行う必要があります。一般に、車両は100ms間隔でサーバへと車両データを送信しますが、車両の周辺環境をもとに送信間隔を調整することでより効率的に通信を行うことができます。そこで、車両から送信される車両データをもとにダイナミックマップ上で送信周期を動的に変化させる手法について提案しています。

Abstract

Much attention has been attracted to the research of cooperative automatic driving that focuses on safety and efficiency by sharing the data obtained from sensor information of a vehicle. In addition, dynamic maps, a common information and communication platform for the integrated management of shared sensor information, are under consideration. A vehicle always sends data to a server that manages the dynamic map, and the server runs applications for driving support and control on the basis of the data, so fast information processing is required. However, congestion is a concern when data is continuously sent from vehicles to the server at high transmission intervals and when many vehicles are managed by dynamic maps on the server. In addition, the data transmission interval from the vehicle required by the road characteristics differs in actual traffic environments. Therefore, congestion can be alleviated by adjusting the transmission interval of data from the vehicle in consideration of road characteristics. In this paper, a platform for a dynamic map consisting of a server and a vehicle is constructed. We have also implemented a priority processing function that sets the priority for each section of a lane, and adjusts the transmission interval on the basis of the characteristics of the road around the vehicle.
