| 摘 要： | 利用车辆运动方程获取车辆行驶距离,车辆当前位置点处的道路方向作为方向角,根据航位推算原理实时推算车辆位置。通过实地跑车试验分别分析了该定位技术在车载导航系统和监控中心的应用。试验结果显示,在车辆导航系统中该技术能实现GPS盲区内的车辆连续定位功能;在监控中心中,该技术从理论上可以大大减少单个车辆和监控中心之间的信息流量,其实际应用还有待智能交通系统的进一步完善。

| Abstract: | Utilizing the vehicle movement equation to obtain the vehicle's running distance,and regarding the road direction of the present position of vehicle as the direction angle,the vehicle position in real time was reckoned according to the dead reckon principle.The applications of this location technology in in-vehicle navigation system and control center were analyzed by field experiment.The field experimental result show that(1)the technology can realize the vehicle navigation in blind area of GPS;(2)the technology can reduce the flow of information between the individual vehicle and control center greatly theoretically in control center.Its practical application still awaits further perfection of the Intelligent Transport Systems. |
