摘　　要：通过设计一个具有双车道带有曲率半径为80 m的弯道的环形道路,作为磁道钉导航的自动公路实验场,说明对道路中磁道钉进行伪随机(PN)编码的方法,给出其纵向定位算法;论述了在多车道的自动公路系统中,通过读取的PN编码与解方程组产生的生成码的匹配运算,确定车辆所在车道和纵向定位;讨论了多条道路汇聚和有匝道的路网的PN编码方法.By designing automated highway virtual field which has two-lane annular road with 80 meters curvature-radius, we gave the method of PN codes and curve information codes for magnetic markers in detail, and described vehicle positioning arithmetic. Also, in multi-path, vehicle can be exactly confirmed its driveway and its position of magnetic markers direction by matching its reading PN codes to replica. At last, we discussed coding method of multi roads such as high ways with on-ramp and off-ramp.
