摘要： In a combine harvester, a travel control portion performs control to enable traveling on a plurality of outermost periphery straight-ahead routes extending along a plurality of sides constituting a farm field outline, respectively. A route creation portion sets, based on machine body information of the combine harvester, a turning necessary area which is necessary for a turn from one outermost periphery straight-ahead route to a next outermost periphery straight-ahead route, and also creates, from a predetermined start point set on the one outermost periphery straight-ahead route toward an unworked land adjacent to an already-worked land which is formed by traveling based on the one outermost periphery straight-ahead route, a predetermined number of inclined routes, which are inclined at a predetermined angle relative to the one outermost periphery straight-ahead route, in the turning necessary area. The travel control portion performs control to enable autonomous straight-ahead traveling along the inclined route.

摘要： A control device includes a first acquiring portion, a second acquiring portion, a generating portion, and a display processing portion. The first acquiring portion acquires first information on a work target region in which a work vehicle travels and works in a field. The second acquiring portion acquires second information on a worked region in which the work vehicle has worked. The generating portion generates progress information indicating progress of a work by the work vehicle on the basis of the first information and the second information. The display processing portion causes an index indicating the progress information to be displayed on the display portion.

摘要： A combine harvester includes a control device and a portable terminal. The control device functions as a discharge run control unit for doing an automatic discharge run based on a discharge route or a return run control unit for doing an automatic return run based on a return route. The portable terminal is provided with a control device, and the control device functions as a discharge route creation unit that creates a discharge route for doing an automatic discharge run in a non-work state from a given transfer position, where a work run is interrupted, to a discharge position as a target position, or a return route creation unit that creates a return route for doing an automatic return run in a non-work state from the discharge position as the given target position to a given return position for returning to the work run.

摘要： In a combine harvester, a terminal-side control device of a portable terminal functions as a route creation unit and a route determination unit. The route creation unit creates an autonomous travel route including a plurality of work routes for performing work in an unworked region of the field and a turning route connecting the two work routes. The route determination unit determines whether the position of the combine harvester during traveling of the combine harvester on the turning route and the position of the field outline satisfy a predetermined positional relationship with regard to the autonomous travel route, confirms the autonomous travel route when it is determined that the predetermined positional relationship is satisfied, and recreates the autonomous travel route to satisfy the predetermined positional relationship when it is determined that the predetermined positional relationship is not satisfied.

摘要： A combine generates an unworked land of an agricultural field through round reaping by which a reaping work is carried out while the vehicle body repeats straight travel and turning. The combine is provided with: a positioning unit that obtains a measurement point indicating a position of a vehicle body; a straight line generating unit that generates a work straight line on the basis of measurement points obtained between a work starting position and a work finishing position of one reaping work; and an unworked land generating unit that calculates, every time the work straight line is generated, an intersection point between the work straight lines intersecting each other, and that, when at least three work straight lines intersect to constitute a closed area, generates an unworked land in a polygonal shape with at least three intersection points being vertices thereof.

摘要： A combine includes a control device and a mobile terminal. The mobile terminal includes a control device, and when the control device detects movement to one field where automatic travel is to be performed, the control device functions as a parameter setting unit that sets a field parameter corresponding to the one field. The control device functions as a travel control unit that executes automatic travel of the combine on the basis of a work route set for the one field and the field parameter.

摘要： A control portion includes a vehicle-position acquiring portion, a field-contour setting portion, a region setting portion, and a start-position setting portion. The vehicle-position acquiring portion acquires position information indicating a position of a combine harvester. The field-contour setting portion sets a contour of a field on the basis of a plurality of pieces of the position information. The region setting portion sets an unworked region inside the contour on the basis of the plurality of pieces of the position information. The start-position setting portion sets a corner closest to a position of the combine harvester among a plurality of corners of the unworked region to an automated-travel start position on the basis of the position information.

摘要： A control portion includes a vehicle-position acquiring portion, a field-contour setting portion, a region setting portion, and a display processing portion. The vehicle-position acquiring portion acquires position information indicating a position of the combine harvester traveling on a field. The field-contour setting portion sets a contour of a field on the basis of a plurality of pieces of the position information. The region setting portion sets a region not subject to a work indicating a region which is not a target for the work by the combine harvester inside the field or outside the field on the basis of the contour. The display processing portion causes a field image showing the field and an identification image for identifying the region not subject to the work, to be displayed on a display portion.

摘要： [Problem] To provide an automatic traveling method, a work vehicle, and an automatic traveling system that enable to proceed automatic traveling smoothly without creating a short automatic traveling route.
[Solution] A combine harvester 1 includes a control device 30 and a portable terminal 40. The control device 30 functions as an automatic traveling control unit 35 that performs automatic traveling on the basis of a created automatic traveling route 64. The portable terminal 40 is provided with a control device 41, and the control device 41 functions as a route creation unit 53 that creates, when a field outline 60 or an outline of an unworked region 61 is set as a target outline and one side that constitutes the target outline is set as a reference line 63, the automatic traveling route 64 as a route that is parallel to the reference line 63. The control device 41 also functions as a reference line setting unit 52 that sets, when one side that constitutes the target outline is equal to or more than a predetermined side length threshold, the one side as the reference line 63.
