ABSTRACT:
An unmanned vehicle guide system has guide routes made of a magnetic material and an unmanned vehicle guided to travel on the guide route. The unmanned vehicle has an exciting coil for emitting a magnetic field, a pair of detection coils, arranged in a direction perpendicular to the travel direction of the unmanned vehicle, for detecting a magnetic field change, a comparator for measuring an output-difference between the detection coils, and a steering device for steering the unmanned vehicle such that the output-difference becomes a predetermined value. At an intersection where a plurality of guide routes intersect and in the vicinity thereof, at least one guide route lacks a magnetic material. Alternatively, an extra marker is added to each of the guide routes that intersect at the intersection.
