摘　　要：传统的车辆定位方法只能获得车辆的具体坐标信息,无法确定车辆位于道路的第几车道。本文提出基于射频识别技术对车辆进行主动定位的定位方法。该方法将RFID阅读器的3组天线的阅读距离设计为特定值,根据阅读器3组天线是否读到标签的不同情况,判定车辆位于第几车道,进而计算出车辆的位置。通过对该方法进行误差分析,结果证明该方法能够完成对车辆在具体车道上的主动定位。The traditional vehicle positioning method only can get the vehicle coordinate information, unable to determine which lane the vehicle is on. This paper proposes an active positioning method for vehicles based on RFID. The reading distance of three antennas of RFID reader is designed as specific value. The vehicle is determined which lane it is located on, according to the different situations whether the reader antennas have read the tags, and then the vehicle position is calculated. The error analysis result shows the method is able to actively locate the vehicle on concrete lane.
