Abstract: A work screen display system including a position information obtaining unit for obtaining position information on a work vehicle based on positioning correction information supplied from a first reference station; a region shape determination unit for determining a shape of a specific region where the work vehicle performs autonomous travel, based on positioning correction information supplied from a second reference station; and a display control unit for displaying, on a display unit, a specific region indication section indicating the specific region determined by the region shape determination unit. The display control unit displays the specific region indication section in a display mode that varies between a case where the first and second reference stations are identical and a case where the first and second reference stations are not identical.

Abstract: The present invention enables generating a desired target travel path intended by a user or the like without the need for various input works for the type, width, and the like of a work machine. The present invention is provided with: a travel path generation unit which generates a target travel path (P) along which a work vehicle is caused to travel automatically; and a reference point setting unit which, on the basis of position information about the work vehicle when the work vehicle has been caused to travel, sets a first reference point (A) and a second reference point (B) for generating a first reference line, and a third reference point (C) for setting intervals, wherein the path generation unit generates, as the target travel path (P), a path that includes a plurality of parallel paths (P2) parallel to the first reference line (P1) based on the first reference point (A) and the second reference point (B), and sets respective intervals between the first reference line (P1) and the parallel paths (P2) and also each interval between the parallel paths (P2), on the basis of a distance between the second reference point (B) and the third reference point (C).

Abstract: Provided are a work region setting portion which sets, within a traveling region, a work region for a working vehicle to perform predetermined work; and a traveling route setting portion which sets, within the traveling region, a target traveling route to make the working vehicle travel automatically. The traveling route setting portion includes: an initial route generation portion which generates an initial route based on a trajectory formed by the working vehicle traveling in the traveling region; a work route generation portion which generates work routes arranged in a parallel arrangement direction orthogonal to an extension direction; and a connection route generation portion which generates connection routes connecting, at either side of the work region, routes adjacent in the parallel arrangement direction among the initial route and the work routes. The target traveling route including the initial route, the work routes, and the connection routes is thereby set.

Abstract: To enter a desired travel route in scheduled travel routes including a plurality of travel routes, and start working from the desired travel route. An automatic travel system is provided with: a route generation unit for generating scheduled travel routes including a plurality of travel routes on which a working vehicle is caused to automatically run; an automatic travel control unit capable of causing the working vehicle to automatically run along the scheduled travel routes; an information acquisition unit for acquiring positional information and orientation information of the working vehicle; and a specifying unit for specifying, before automatic travel is started by the working vehicle, an automatic travel candidate route on which the working vehicle can start the automatic travel. On the basis of the positional information and the orientation information of the working vehicle which are acquired by the information acquisition unit, the specifying unit sets a candidate specification area ahead of the working vehicle and in the rear thereof, and specifies, out of the plurality of travel routes, a travel route included in the candidate specification area as an automatic travel candidate route.

Abstract: This autonomous travel system is provided with a farm field acquisition unit, a reference auxiliary line creation unit, an adjacent auxiliary line creation unit, and a travel control unit. The farm field acquisition unit acquires information regarding a farm field that includes a work area and a headland area. The reference auxiliary line creation unit creates first reference auxiliary lines within the headland area at positions spaced apart from the farm field peripheral edge on the inner side thereof by a first reference interval. The adjacent auxiliary line creation unit creates, at each of auxiliary line intervals, first adjacent auxiliary lines at positions spaced apart from the first reference auxiliary lines on the inner sides thereof. The total number of first reference auxiliary lines and first adjacent auxiliary lines created on the inner side of one predetermined side of the farm field peripheral edge is a value obtained by rounding up to a value equal to or less than the decimal of the headland width L/the auxiliary line interval S. The travel control unit causes a work vehicle to travel autonomously along at least some of the first reference auxiliary lines and the first adjacent auxiliary lines.
