Container transport system using autonomous driving method and container transport method using autonomous driving method

A container transportation system using autonomous driving, comprising:

• a container to be transported;
• at least two autonomous vehicles docked with or undocked from the container and autonomously travelling to transport the container to a transport destination;
• and
• a management server controlling travelling of the autonomous vehicles,
• wherein each of the autonomous vehicles comprises a vehicle body and a container coupling part coupled to the container, the container coupling part comprising:
• a docking body having a lower portion coupled to an upper surface of the vehicle body and an upper portion having one of a curved shape or a side surface cut at a predetermined angle;
• and
• a groove formed at a center of the docking body such that a center of the docking body is smaller in length and area than upper and lower surfaces of the docking body,
• wherein the container comprises:
• a container body;
• a plurality of height adjustment pillars coupled to respective corners of a lower surface of the container body and adjustable in length to lift or lower the container body from or to the ground;
• and
• at least two vehicle coupling parts formed on the lower surface of the container body and coupled to the respective container coupling parts, each vehicle coupling part comprising:
• an insertion hole formed on the lower surface of the container body in a shape corresponding to a shape of the container coupling part;
• a fastening bar disposed at a side of the insertion hole, wherein at least a portion of the fastening bar protrudes into the insertion hole;
• and
• a spring connected to another portion of the fastening bar.

A container transportation method using autonomous driving based on a container transportation system using autonomous driving, comprising:

• transmitting, by a management server, transport information of a container to be transported by an autonomous vehicle to the autonomous vehicle;
• moving the autonomous vehicle to a location at which the container is stored based on the transport information;
• coupling the autonomous vehicle to the container,
• wherein the autonomous vehicle comprises a vehicle body and a container coupling part coupled to the container, the container coupling part comprising:
• a docking body having a lower portion coupled to an upper surface of the vehicle body and an upper portion having one of a curved shape or a side surface cut at a predetermined angle;
• and
• a groove formed at a center of the docking body such that a center of the docking body is smaller in length and area than upper and lower surfaces of the docking body,
• wherein the container comprises a container body and a vehicle coupling part, the vehicle coupling part comprising:
• an insertion hole formed on the lower surface of the container body in a shape corresponding to a shape of the container coupling part;
• a fastening bar disposed at a side of the insertion hole, wherein at least a portion of the fastening bar protrudes into the insertion hole;
• and
• a spring connected to another portion of the fastening bar,
• wherein the fastening bar is configured to:
• be pressed by the container coupling part to move in a direction away from the insertion hole as the container coupling part is inserted into the insertion hole, and
• move back toward the insertion hole by restoring force of the spring to be inserted into the groove as the fastening bar and the groove are positioned in parallel to each other;
• transporting, by the autonomous vehicle, the container to a transport destination based on the transport information;
• and
• uncoupling the autonomous vehicle from the container.
