ABSTRACT:
A reference point recognizing system for a steering control system comprising a light beam scanner and a beam receiver on a moving vehicle, the light beam scanner scanning a light beam generated in a light beam generator in the circumferential direction while vertically swinging it. The system determines azimuths of light from light reflector reference points detected in the beam receiver in response to the light beam scan prior to the traveling of the moving vehicle. A memory stores the azimuths of the lights and the number of times each of lights are detected. The system determines when the detection of lights in particular azimuths has reached a predetermined number, recognizes when an incident light is detected from substantially the same direction a predetermined number of times or more, and treats that substantially same direction as the azimuth of a predetermined light reflecting means.
