| 摘 要： | 为提高车辆获取位置信息的准确性,基于RFID（射频识别）技术提出一种车辆位置信息辅助系统,在本系统中,将RFID标签铺设至路面上,为装有RFID读卡器车辆提供准确的道路和位置信息系统.根据标签中提供的位置信息,利用车间通信,并依据车辆的运行状态,让无RFID车辆同时能够计算出自身的位置,达到信息扩散与共享的效果.本文结合8种不同的道路状况,进行仿真实验.结果表明：本系统能够在不同的道路状况下良好运行,实现位置信息的扩散与共享.

| Abstract: | In order to enhance the accuracy of the vehicle location information,a position information sharing system is proposed based on RFID technology. RFID labels are deployed on the road to provide the road information for the vehicles with RFID reader installed. This system is based on the position information in the label,vehicle-to-vehicle communications and the state of vehicles which help the vehicles without RFID system to calculate the position and achieve the information diffusion and sharing. 8 different road conditions are defined in the simulations. The simulation results show that this system works well under different road conditions to diffuse and share the location information. |
