A steering control system wherein a light beam emitted from the moving vehicle and reflected by plural reflecting means disposed apart from and around the moving vehicle, is received by a beam receiver means mounted on the vehicle. A current position of the vehicle is detected based on the output of the beam receiver means. The steering angle of the vehicle is fixed at a predetermined value when the moving vehicle is at a switching point where a straight traveling course is to be changed into a turning course, and is released when it is detected that any one of azimuthes of the light-reflecting means viewed from the moving vehicle substantially coincides with a predetermined azimuthal angle, or has exceeded the predetermined azimuthal angle.

A steering control system for use in a moving vehicle wherein a light beam emitted from the moving vehicle is scanned in all the different azimuthal directions around the moving vehicle, and the light reflected by reflecting means disposed at at least three positions apart from and around the moving vehicle, respectively, is received in order by a beam receiver means mounted on the moving vehicle and rotating in a horizontal plane, whereby positional information of the moving vehicle is detected on the basis of the output of the beam receiver means so that the moving vehicle is traveled On the basis of the positional information along a straight traveling course and the succeeding turning course, comprising means for detecting differential azimuthes between two adjoining light-reflecting means centering around the moving vehicle: means for controlling steering of the moving vehicle in a straight traveling course based on the differential azimuthes; means for fixing the steering angle of the moving vehicle at a predetermined angle at the time when the moving vehicle positions at a switching point where a straight traveling course is to be changed into a turning course; detection means for detecting a substantial coincidence of any one of azimuthes of the respective light-reflecting means viewed from the moving vehicle with a predetermined angle which has been set so as to be compared with the azimuth; and means for releasing the fixation of the steering angle in response to a detection signal of the detection means.
