Patent ID: 8188892

Claim:
A moving vehicle system comprising: a moving vehicle with a detection head having a coil array comprising a plurality of coils along a moving direction of the moving vehicle; a first segment where magnetic marks are arranged along a moving route of the moving vehicle at a pitch equal to a length of the coil array in order to determine a position of the moving vehicle in the first segment continuously based on an output from the detection head; a second segment where the magnetic marks are arranged along the moving route at, at least, an interval that is wider than the pitch minus the length of the coil array; and means for detecting a presence of the magnetic mark to identify whether the moving vehicle is running along the first segment or the second segment, and means for changing a detection range of the detection head to output the position of the moving vehicle with predetermined precision over an entire range in the first segment, and output the position of the moving vehicle with the predetermined precision in the second segment for an area around the magnetic mark being that is narrower than the pitch.
