摘要
近年来,基于专用短程通信技术的车辆碰撞协同预警系统的研究受到广泛关注,高精度、低延迟、高可靠性的车辆定位和测距信息是实现车辆碰撞协同预警的前提。介绍了多种定位与测距技术的研究进展,对比分析了其应用于车辆碰撞协同预警系统的适用性与局限性,提出了相应的解决方法和发展方向。
CCWS(Cooperative Collision Warning System) based on DSRC has been received wide concern in recent years,while high accuracy,low latency and high reliability vehicle location and ranging information are the premises of vehicle collision warning coordination.A variety of localization and ranging technologies are introduced,and their pros and cons in CCWS are also analyzed in this paper.Finally,some solutions and developing trends are discussed.
