Abstract
A system for automatically controlling movement of an unmanned vehicle and method therefor wherein one or more than one marker is installed between each branched corner formed by a guide road through which the vehicle passes for providing an indicating means for the vehicle to accelerate, decelerate, or turn the branched corner and the vehicle includes detecting means for detecting the presence of the marker and outputting a signal indicating that the marker is located at the corresponding position and a controller in which data and main program on a pattern of turning the movement of the vehicle at any given branched corner and vehicle speed control according to the detected number of markers in accordance with a route of movement from a starting point which is loaded prior to the start of the vehicle so that the control for turning the movement direction of the vehicle and vehicle speed is carried out by fetching the corresponding above-described data and main program of the pattern according to the number of detected markers. Furthermore, at least one timer is provided in the controller which outputs an interrupt signal so that an interrupt program is executed for controlling an…
