摘　　要：嵌入式车辆自主导航系统是将定位技术、地理信息系统、嵌入式开发技术与LBS思想结合起来用于车辆实时导航的位置服务系统。作为智能交通系统的重要组成部分,自主导航系统在新时期"互联网+智能交通"的建设中有着广阔的研究空间。为了解决现有主流导航系统中存在的导航服务及地理信息表达模式单一的问题,基于Reworks/Rede开发平台设计并实现了多任务型嵌入式自主导航系统。最后,系统在龙芯3A国产嵌入式平台上进行了测试,实践证明,该系统提高了实时导航中地理信息传递的准确性和效率,具有较强的实用性。The embedded vehicle autonomous navigation system is a position service system that combines the positioning technology,geographic information system,embedded development technology and LBS idea. As an important part of the intelligent transportation system,the autonomous navigation system has a broad research space in the construction of ＂ Internet ＋ Intelligent Transportation＂. In order to solve the problem of lacking of adaptability in navigation service and geographic information expression among the mainstream navigation system,this paper designs and realizes the multi task embedded autonomous navigation system based on Reworks / Rede development platform. Finally,the system was tested on the Loongson 3A domestic embedded platform. Practice proved that the system can improve the accuracy and efficiency of geographic information’s transmission in real-time navigation,and has lot of practicability.
