Abstract

When an automatic operation is finished, a detection process for detecting a ground contactable range where a work implement can be set is carried out on a basis of terrain profile information acquired by laser scanners, and, when the ground contactable range is detected, an automatic operation command signal for placing the work implement in contact with the ground contactable range is generated, whereas when the ground contactable range is not detected, an automatic operation command signal for placing the work implement in a predetermined standby posture is generated. As a result, a suitable standby posture can be taken according to the surrounding conditions when the automatic operation is finished.
