Position-detecting and steering control system for moving vehicle

摘要

A steering control system for a moving vehicle wherein a light beam emitted from the moving vehicle is scanned along the circumferential direction thereof, and the light beam reflected by light-reflecting means disposed at at least three reference points is received to detect a position of the moving vehicle comprising, an azimuth detection means for detecting azimuths of the respective light-reflecting means, a position calculation means for calculating the position of the moving vehicle based on the azimuths detected, and a means for stopping travel of the moving vehicle when a following beam signal has not been detected over a predetermined period of time after detecting a preceding beam signal from a particular light reflecting means. It may comprise an azimuth prediction means for predicting an azimuth of the light-reflecting means to be detected in the next scanning cycle and an azimuth presumption means for presuming the azimuth of the light-reflecting means which is not detected when the light-reflecting means is not detected in the predicted azimuth.
