ABSTRACT:
An automatic travel control method for a unmanned vehicle system is performed on the basis of signals indicating the existence of the curvature of a guide path and right and left digital signals indicating the degree of the curvature of the guide path. In the method, (1) where the guide path is straight, the steering of the vehicle is controlled based on both the right and left digital signals; (2) where the guide path is curved to the right, the steering of the vehicle is controlled based on the right digital signal; and (3) where the guide path is curved to the left, the steering of the vehicle is controlled based on the left digital signal. The curvature existence detecting operation is performed according to the levels of the voltage signals induced to a pair of voltage generating devices located at the right and left sides of the vehicle after generating a magnetic field by applying alternating current to the guide path. The right and left digital signals generating operation is performed by converting the voltage signals induced to the pair of voltage generating devices into corresponding digital signals. An automatic travel control apparatus is also provided.
