Embodiment Construction

[0084] [Outline of automatic driving]

[0085] exist figure 1 Schematically shows the work travel performed by the work vehicle automatic travel system of the present invention. In this embodiment, the work vehicle is a harvester 1 for a harvesting operation (harvesting operation) for harvesting crops while traveling as a work vehicle, and is generally a model called a general-type combine harvester. A work place where the harvester 1 operates and travels is called a farmland. In the harvesting work in the farmland, an area in which the harvester 1 circles while working along the boundary line of the farmland called a ridge is set as the outer peripheral area SA. The inner side of the outer peripheral area SA is set as the work target area CA. The outer peripheral area SA is used as a space for movement, a space for direction change, and the like in which the harvester 1 discharges and replenishes the harvested material. In order to secure the outer peripheral area SA, the...

Abstract

The automatic travel system for the work vehicle includes: a satellite positioning module 80 that outputs positioning data indicating the position of the work vehicle 1 ; an area setting unit that sets a work target area CA of a work site; and a route management unit that calculates a composition network The travel route element group, which is an aggregate of a plurality of travel route elements of the travel route in the work target area CA, is stored so as to be readable; the route element selection unit sequentially selects the next travel route to be traveled from the travel route element group element; an automatic travel control unit that automatically travels the work vehicle 1 based on the next travel route element and the position of the vehicle.

Description

technical field [0001] The present invention relates to an automatic travel system for a work vehicle that manages the automatic travel of a work vehicle that travels while working on a work site, and a travel route management device that manages the travel route of the work vehicle. [0002] Furthermore, the present invention relates to a travel route generation device for generating a travel route of a work vehicle that travels while working on a work site. [0003] Furthermore, the present invention relates to a travel route determination device for determining a travel route of a work vehicle that automatically travels while working on a work site. Background technique [0004] The farm work machine of Patent Document 1 includes a route calculation unit and a driving assistance unit in order to perform farm work while automatically traveling. The route calculation unit obtains the outer shape of the farmland from the terrain data, and calculates a travel route from the ...
