Guidance control system for autonomous-traveling vehicle

A guidance control system for an autonomous vehicle, the guidance control system comprising:

• an antenna position compensation module for providing guidance control signal to the autonomous vehicle during selection of a virtual antenna position;
• a vehicle navigation module for providing guidance control signal to track the navigation of the autonomous vehicle based on pre-defined path data;
• and
• a lateral control module connected to the antenna position compensation module for controlling a lateral error,
• wherein the autonomous vehicle performs an autonomous navigation and operation while a position of the autonomous vehicle is measured using a satellite navigation system, and
• wherein when the autonomous vehicle moves backward, the virtual antenna position is set in a backward position by a predetermined distance from an antenna position for receiving a signal from the satellite navigation system, and a lateral control is performed using the lateral error from a pre-defined path at the virtual antenna position.
