AUTO - RETURNING SYSTEM OF AUTONOMOUS VEHICLE, AUTONOMOUS VEHICLE HAVING THE SAME AND AUTO - RETURNING METHOD OF AUTONOMOUS VEHICLE

摘要

PURPOSE: An autonomous return system, an autonomous mobile vehicle including the same, and an autonomous travel method of the autonomous mobile vehicle are provided to switch an absolute position estimation process and a relative position estimation process by setting the number of usable GPS(Global Positioning System) satellites as a judgment standard. CONSTITUTION: A location receiver receives position data of a main body. A satellite tracking part tracks the number of GPS(Global Positioning System) satellites(110). A driving method determination part determines a driving method according to the number of tracked GPS satellites. An operation part based on an absolute location includes an absolute location determination part and a first path setting part. An absolute position of a main body is determined by an absolute position determination part. A first route determination part outputs a return command to a driving control part. A controller(100) manages inputted and outputted information.
