摘 要: 针对车道定位对智能交通发展的应用需求,利用射频识别(radio frequency identification,RFID)技术和车载诊断(on-board diagnostic,OBD)系统的有机结合,设计并实现了一种车道级的车辆主动定位系统。使用RFID 信标定位获得车辆的位置和车道信息,并建立全局车辆道路坐标系;通过OBD 实时获取可靠的车辆行驶角度和瞬时速度,采用速度矢量积分算法获得车辆精准的运动信息,根据地图匹配坐标并显示车辆位置信息。试验证明,该方法可以完成车辆在车道上的准确定位,与传统单一的定位方法相比,具有更好的准确性和较高的实用价值。
关 键 词: 电子、通信与自动控制技术其他学科;射频识别;车道定位;车载诊断;智能交通;惯导系统

Abstract: According to the application requirements of lane-level positioning for intelligent transportation, an active location system that can distinguish the lane is implemented by combining the technology of radio frequency identification (RFID) with the on-board diagnostic (OBD). The location of the vehicle and lane information are calculated by RFID beacons and used to establish a global road coordinates. The vertical’s reliable angle and instantaneous speed are obtained in real time with the help of OBD, and the accurate vehicle movement information is obtained by using the velocity vector, then the location is matched and showed on map. Experiment results show that the method can position the lane which the car is running on, resulting in higher accuracy and better practicability than the traditional single positioning methods.
