Abstract
A position detecting system of a moving vehicle wherein a light beam scanned around the vehicle to be reflected by reference retroreflective means is received on the vehicle, the azimuth of each retroreflective means to be detected in the next scan is predicted, the azimuth of a particular incident light which forms the smallest angle with the predicted azimuth and is detected between two reference point discrimination azimuths preset at both sides of the predicted azimuth is judges to be that of an expected reflecting means and utilized for the position detection of the moving vehicle. When the expected retroreflective means is missed in a turning course, a previously known included angle which is formed by two straight lines connecting a turn center to said missing retroreflective means and another retroreflective means disposed just before, respectively, is added to the azimuth of the another retroreflective means in the next scan, and the resultant sum angle is used as the azimuth for the missing retroreflective means.
