车联网关键技术及其发展趋势与挑战

Key Technologies of Internet of Vehicles and Their Development Trends and Challenges

车联网是未来智能交通的重要组成部分,也是目前国内外研究的热点问题。围绕车联网,综述了其关键技术及其研究进展,并展望了该领域的发展趋势及其挑战。车联网由感知层、网络层和应用层组成,利用V2X技术实现人、车、路、云之间的信息交互。车内网通过整体感知、定位和语音识别等技术来构建单车网络;车际网通过移动边缘计算、软件定义网络、网络切片和区块链等技术实现车辆的智能互联。未来车联网将与5G技术深度融合,实现车车/车路协同控制与自动驾驶。

The IoV(the Internet of Vehicles)is an important part of intelligent transportation,and it is also a hot topic of research at home and abroad.Focusing on IoV,its key technologies and research development are summarized,and the development trends and challenges in this field forecasted.The IoV,composed of the perception layer,the network layer and the application layer,uses V2X technology to realize the information interaction among people,vehicles,roads,and clouds.The intra-vehicle network constructs a single vehicle network through the technologies of overall perception,positioning and voice recognition,while the intervehicle network realizes the intelligent interconnection of vehicles through the technologies involving mobile edge computing,software-defined network,network slicing and block chain.In the future,the IoV will be deeply integrated with 5G technology to realize the vehicle-vehicle/the vehicle-road collaborative control and the autonomous driving.
