Work position guide apparatus of autonomous yard tractor

A work position guide apparatus for guiding an autonomous yard tractor to a work position, the apparatus comprising:

• a reference position determination unit that determines at least one reference position coupled to a spreader of a crane located at the work position according to a size and number of containers in the autonomous yard tractor;
• a real-time position detection unit that detects a real-time position of the autonomous yard tractor;
• an error data acquisition unit that acquires error data between the reference position and the real-time position;
• and
• a guide command generation unit that generates a guide command for guiding the autonomous yard tractor to the work position based on the error data,
• wherein the reference position determination unit obtains a coordinate value of the work position based on the positions of a plurality of lanes included at the bottom of the crane included in the work position, and acquires a coordinate value of the at least one reference position based on the coordinate value of the work position.
