嵌入式车载导航电子地图的设计和实现

摘要

The vehicle navigation hardware and GIS software development for the vehicle remote terminal apparatus are studied in detail.A circuit with the SH7764 microprocessor by Renesas Electronics Company as the core is presented.The system structure and data management of the embedded electronic map are discussed.The second integration and development in MapX Mobile are also introduced.This system has been run in the experimental vehicles of Shanghai Pan Asia Technical Automotive Company Limited for more than two years,and proves reliable and can satisfy basic needs.%针对车辆远程终端仪中车载导航的硬件构成和GIS软件开发进行了探讨。给出了以Renesas Electronics公司SH7764微处理器为核心的电路图,对嵌入式电子地图的体系结构、数据管理等进行了论述。同时介绍了在MapXMobile下进行二次集成开发的过程。此系统在上海泛亚汽车技术有限公司实验用车上运行了两年,实际证明系统运行可靠,能满足生产的基本需求。
