摘　　要：鉴于车辆位置精度对车联网应用的重要性和传统的卫星定位系统在城市"高楼峡谷"或隧道等弱卫星信号覆盖区域失效或定位精度不足等问题,本文中研究了基于V2X通信网络的车辆定位方法,研发了专用短程通信和多模式通信网络定位终端,完成了终端的性能测试和应用部署,设计了基于多模型滤波算法的车辆协作定位增强方法。结果显示,与传统GPS定位相比,本文方法能提升定位精度近40%。In view of the importance of vehicle positioning accuracy to the application of Internet of Vehi-cles and the problems of inadequate positioning accuracy and failure of traditional satellite positioning system in weak signal coverage areas like urban canyons and tunnels,a vehicle positioning method based on V2X communica-tion network is investigated in this paper.The positioning terminals of dedicated short range communications and multi-mode communications network are developed with their performance testing and application deployment com-pleted,and the vehicle cooperative positioning enhancement method based on multiple-model filtering algorithm is designed.The results show that the method proposed can increase positioning accuracy by nearly 40%,compared with traditional GPS-based method.
