Abstract: An exemplary work vehicle includes a steering wheel, a steering shaft that supports the steering wheel, a steering motor that enables automatic steering of the steering wheel, and a switching mechanism that switches a power transmission state existing between the steering motor and the steering shaft between a connection state and a shutoff state.

Abstract: A route setting device is provided with a status confirmation part and a change route setting part. The status confirmation part receives, with respect to a work vehicle that is moving along a preset work route in a field, an instruction by which the work vehicle moves to a stop position not included in the work route, and acquires the position of the work vehicle. The change route setting part creates a change route along which the work vehicle moves to the stop position on the basis of the instruction. The starting point of the change route represents the position of the work vehicle at a time when a waiting time for change equaling or exceeding a delay time set on the basis of the processing time for creating the change route has elapsed after receiving the instruction.

Abstract: A detection process unit detects an error of at least any of a plurality of work vehicles. A report process unit causes, when an error of a work vehicle among the plurality of work vehicles is detected, specific information on the work vehicle to be reported at an operation terminal communicable with each of the plurality of work vehicles.

Abstract: A combine harvester includes a control device configured to function as a travel route creation unit, an automatic drive control unit, a course movement unit, and a course correction unit. The travel route creation unit creates, in a yet-to-be-reaped area of a field, a travel route that includes parallel first and second straight-line courses. The automatic drive control unit performs control on automatic driving and automatic reaping based on the travel route. While automatic reaping travel is conducted on the first straight-line course, the course movement unit modifies the travel route by moving the first straight-line course in a direction intersecting with the traveling direction. When movement of the first straight-line course results in movement of the first straight-line course in one direction, the course correction unit corrects a portion of the second straight-line course toward the same one direction.

Abstract: A display device includes a display unit; a control unit; an alarm sound output unit; and a reception unit. When the display unit displays a second screen, the control unit assigns, to the reception unit, a function of receiving an output stop instruction that indicates an instruction to stop the output of an alarm sound, and a function of receiving a second instruction that indicates an instruction to transition to a first screen. When the reception unit receives the output stop instruction, the control unit stops the output of the alarm sound. When the reception unit receives the second instruction after having received the output stop instruction, the control unit causes the display unit to display the first screen and causes the alarm sound output unit to output the alarm sound.

Abstract: An acquisition processing part acquires detection information from a first obstacle sensor which detects an obstacle in a first detection area, and a second obstacle sensor which detects an obstacle in a second detection area. When an obstacle is detected in the first detection area, a traveling processing part executes travel restriction of a work vehicle. When the obstacle enters a non-detection area from the first detection area in a state in which the work vehicle is under the travel restriction, a determination processing part determines whether or not the obstacle further enters the second detection area from the non-detection area. When it is determined that the obstacle enters the second detection area from the non-detection area, the traveling processing part continues the travel restriction of the work vehicle.
