摘　　要：首先概述了磁道钉编码的结构和应用方式,在此基础上,为防止磁编码被误读,提出了基于海明码的磁道钉编码差错控制技术,阐述了磁编码差错控制技术的基本原理、具有差错控制功能的磁编码信息结构以及信息表达应用方案,并在交通部公路交通试验场和新疆塔城地区进行了道路试验和工程应用。试验应用表明,该差错控制技术可以保证磁道钉编码技术的稳定可靠应用,从而为车辆自动驾驶和辅助驾驶系统提供道路结构方面的准确信息,提高自动驾驶和辅助驾驶的稳定性和安全性。Magnetic markers coding technology of Intelligent Highway System which is based on the magnetic markers in the road is a novel and intelligent method for roadway structure information expression. In order to avoid the decoding and reading mistake, a mistake control technology based on Hamming code was proposed for magnetic markers coding, its principle, structure and information expression method were introduced in detail, and the test in Proving Ground for Highway and Traffic of MOC and application in Tacheng of Xinjiang Autonomous Region were presented as well. The experimental result indicates that the mistake control technology could guarantee the stable and reliable operation of magnetic markers coding technology, thus provides the accurate information of roadway structure for the vehicle＇ s intelligent system, and enhances the stability and safety of automated driving and assistant driving.
