摘要
介绍车辆导航定位及其组合导航定位技术。组合导航利用现代信息融合技术 ,实现对车辆组合导航的准确定位 ,具有全方位、全天候、自主式定位功能。着重研究了GPS/GLNOASS/MM和GPS/DR/MM三组合导航定位及跑车试验分析。跑车试验表明 ,车辆组合导航定位精度及可靠性比单独GPS导航定位有所提高 ,车辆运行效率和安全性大大改善 ,提高了通行能力 ,有效地缓解了交通拥挤状况 ,从而为实现交通管理“自动化”以及车辆行驶“智能化”提供了可靠的保证。
The technologies of navigation and positioning and the different integration methods of vehicle navigation and positioning for vehicle are introduced in this paper. The utilization of modern information fusion technologies realize vehicle integrated navigation and positioning which have all-direction, 24 hours standby and automatic positioning characteristics. The special attention is paid to the research of integration of GPS with dead-reckoning and map matching, GPS with GLONASS for vehicular navigation, and the analysis of their experiments for vehicles. The experiments for operating vehicles demonstrate that the degree of accuracy and reliability integrated navigation and positioning for vehicle, compared with independent GPS navigation and positioning, is enhanced, vehicular operation efficiency and security are far and away strengthened, and the thoroughfare capability is improved. As consequence traffic congestion can be moderated with effect and the automation of transportation management and the intelligence of vehicular drive will be realized. \;
