  • Publication number: 20240032452
    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.

  • Publication number: 20240028037
    Abstract: An autonomous travel system causes a work vehicle to autonomously travel along an inter-field route preset for a road connecting a field and a field. A travel processor causes the work vehicle to be stopped at a route start position of the inter-field route and to resume autonomous travel when a user is within a predetermined distance from the work vehicle in the field corresponding to the stop position of the work vehicle. An announcement process unit causes the work vehicle to announce travel information about travel on the inter-field route in the field.

  • Publication number: 20240016089
    Abstract: A combine is provided with a control device configured to function as a route generation unit, a position setting unit, a mid-work route generation unit, or a self-driving control unit. The route generation unit generates a travel route by combining a plurality of routes for an unreaped region in a field. To perform mid-work corresponding to the work amount of reaping traveling at a preset mid-work position, the position setting unit sets an interruption position at which automatic reaping traveling is interrupted to the end point of a predetermined interruption route based on the work amount. To perform the mid-work, the mid-work route generation unit generates a mid-work route extending from the interruption position to the mid-work position. The self-driving control unit controls traveling and reaping based on the travel or mid-work route.
