摘　　要：车联网是未来汽车的发展方向,也是信息化社会的必然需求。4G移动通信系统为车联网的实用化提供了关键的无线信道资源。为了使车联网尽快投入使用,研究了车联网的运用模式和系统结构,设计了车载终端和车联网信息中心,创新性地提出了智能导航、智能交管、信息发布、车间通信等车上应用的技术原理和实现方案,并研制了系统样机。通过样机验证,系统可提供多种车上信息服务,可有效提高车辆信息化水平,提高道路通行效率和车辆管理水平。The internet of vehicles is the development direction of future vehicles, and also the necessary requirement of the information-based society. The key wireless channel resources are provided by 4G mobile communication system for the inter- net of vehicles. In order to make the internet of vehicles into practice quickly, the application mode and system structure of the internet of vehicles are studied, and the vehicle terminal and information center of the internet of vehicles were designed. The technology principle and implementation scheme for the vehicles applications （intelligent navigation, intelligent traffic manage- ment, information publishment and inter-vehicle communication） are proposed, and the system prototype was development. The experiment with the prototype proves that the system can provide a variety of information services, improve the information level of vehicles effectively, and enhance the passing efficiency of the roads and management level of the vehicles.
