摘要
车联网相比于传感器主动探测能够应用到具有遮挡的场景、可探测更远的距离和具有应对恶劣天气的能力,DSRC即专用短程通信技术,作为IEEE组织推动的车联网技术,已经建立了包括802.11p和1609.X协议规范。本文分析DSRC通信标准的专利布局,统计分析全球的专利申请态势、主要申请人分布,介绍了通信安全重点分支的技术发展历程,并绘制了技术发展路线图。
Compared with active sensor detection, vehicle networking boasts more advantage in shielding or oc-clusion scenario. Besides, it rests higher detecting range and could be used in unfavorable weather situation. Dedi-cated Short-Range Communications, DSRC in short, which was proposed by IEEE, has two protocol stacks 802.11p and 1609.X get published. In this paper, Patent analysis is used to analyze the current status and the trends of appli-cation, the distribution of applicant in this field, etc. A key branch communications security is investigated, and the technology development route is introduced.
