车联网是能够对车用信息进行采集、识别、传输、融合和利用的一体化网络,是物联网技术在交通系统领域的典型应用.它建立了将人、车、路智能信息交互的平台,是未来车辆安全、环保、道路利用效率发展的重要研究方向.本文通过介绍车联网的基本概念以及国内外车联网的发展现状、应用趋势,为进一步的研究打下基础.车联网的整体结构可以分成三个层次:硬件平台、系统软件和应用软件。车联网硬件平台:由多种传感器及信号处理电路构成,包括电源转换、信号处理、数据处理及存储等。硬件平台是车联网的基础,也是信息的来源,通过传感器将车辆外的环境信息、车内的信息转换为能够被控制中心处理识别的信号。车联网系统软件层:由系统管理、通信系统、无线通信及语音构成,系统软件层在车联网中为中枢部分,能够将硬件平台得到的信息进行传递和处理,目前,已经制定了车载环境下无线接入的相关协议。车联网应用软件层:主要结合不同的用户需求提供不同的应用,利用车联网对车辆进行控制、安全驾驶,在智能交通系统中应用并提供相应的信息服务等。
