A method for controlling work traveling for an automatic traveling work vehicle along a travel route, comprising: - determining an own vehicle position based on positioning data from a satellite positioning module by an own vehicle position calculation unit; - generating the travel route by a travel route generation unit; - generating a work event plan defining a work event performed during the work traveling by a work event planning unit; - controlling automatic traveling along the travel route by a travel control unit; - generating an actual work event command based on the travel route, the work event plan, and the own vehicle position by an actual work event command generation unit; and - controlling execution of the work event based on the actual work event command by a work control unit; characterized by - providing the travel route generation unit, the work event planning unit, and a the virtual work event command generation unit in a first controlling unit; - providing the actual work event command generation unit in a second controlling unit; - providing a work traveling monitoring unit in a third controlling unit; - providing the first controlling unit, the second controlling unit, and the third controlling unit as an independent control system; - operating independently of one another the first controlling unit, the second controlling unit, and the third controlling unit; - generating a virtual work event command based on the travel route, the work event plan, and the own vehicle position by the virtual work event command generation unit; - determining by the work traveling monitoring unit an abnormality of the work traveling when the actual work event command and the virtual work event command do not correspond to each other, and outputting abnormality information; and - performing an abnormality process to recover the abnormality according to the content of the abnormality information by an abnormality processing unit, wherein the abnormality process includes - stopping a vehicle body; - stopping a tilling device; - forced changing from automatic operation to manual operation; and - warning through a notification device operated by a control signal from a notification unit. - determining an own vehicle position based on positioning data from a satellite positioning module by an own vehicle position calculation unit; - generating the travel route by a travel route generation unit; - generating a work event plan defining a work event performed during the work traveling by a work event planning unit; - controlling automatic traveling along the travel route by a travel control unit; - generating an actual work event command based on the travel route, the work event plan, and the own vehicle position by an actual work event command generation unit; and - controlling execution of the work event based on the actual work event command by a work control unit; - providing the travel route generation unit, the work event planning unit, and a the virtual work event command generation unit in a first controlling unit; - providing the actual work event command generation unit in a second controlling unit; - providing a work traveling monitoring unit in a third controlling unit; - providing the first controlling unit, the second controlling unit, and the third controlling unit as an independent control system; - operating independently of one another the first controlling unit, the second controlling unit, and the third controlling unit; - generating a virtual work event command based on the travel route, the work event plan, and the own vehicle position by the virtual work event command generation unit; - determining by the work traveling monitoring unit an abnormality of the work traveling when the actual work event command and the virtual work event command do not correspond to each other, and outputting abnormality information; and - performing an abnormality process to recover the abnormality according to the content of the abnormality information by an abnormality processing unit, wherein the abnormality process includes - stopping a vehicle body; - stopping a tilling device; - forced changing from automatic operation to manual operation; and - warning through a notification device operated by a control signal from a notification unit. - stopping a vehicle body; - stopping a tilling device; - forced changing from automatic operation to manual operation; and - warning through a notification device operated by a control signal from a notification unit.
