摘　　要：对eBoxII用做车载导航系统的可行性进行了研究,实现了基于嵌入式开发设备eBoxII的车载导航系统.完成了系统中语音数据和海量地图数据的存储、地图显示的优化、语音同步播报、后台通信服务等关键技术。该车载终端为上海交通信息网格3.0版的移动导航终端,由后台交通网格系统提供支撑服务。大量实验数据表明,该车载终端具有较高的运行效率。The feasibility ofeBoxⅡ used as vehicle navigation system is discussed. Vehicle navigation system based on embedded development device eBoxⅡ is implemented. The storage of voice data and massive map data, the optimization of map display, the synchronization of voice broadcasting, the background communications services and other critical technologies are completed. The system is used for mobile navigation terminal of the 3.0 version of Shanghai traffic information grid and is supported by background traffic grid system. Extensive experimental data show that the traffic terminal is efficient.
