To provide an autonomous travel work vehicle contributing to autonomous travel by efficiently making an automatic control device recognize a planar shape of a field.SOLUTION: An autonomous travel work vehicle 1 performs farm work while autonomously traveling in a field by positioning longitudes and latitudes of a starting point S, a first inflection point A and a second inflection point B by going around the field, recognizing a flat surface surrounded by the three points as a first field surface AB, and recognizing a triangle flat surface BC surrounded by the longitude and latitude of a third inflection point C, and a line connecting a starting point A and the second inflection point B. The autonomous travel work vehicle of the field repeats until circling is ended, a work of adding to the first field surface AB when the triangle flat surface BC is not overlapped on the first field surface AB, and subtracting when it is overlapped, and stores a work field area obtained by adding/subtracting the longitudes and latitudes of the starting point S and the respective inflection points A, B... in field data of the automatic control device.SELECTED DRAWING: Figure 6

    【課題】圃場の平面形状を効率良く自動制御装置に認識させて自律走行に役立てることができる自律走行作業車を提供する。【解決手段】圃場内を自律走行して農作業を行う自律走行作業車1において、圃場を周回して出発地点Sと第一曲点Aと第二曲点Bの経緯度を測位してこの三点で囲まれる平面を第一圃場面ABと認識し、第三曲点Cの経緯度と出発地点Aと第二曲点Bを結ぶ線に囲まれる三角平面BCを認識して、三角平面BCが第一圃場面ABと重ならない場合は第一圃場面ABに加算し、重なる場合は減算する作業を周回が終わるまで繰り返し、出発地点Sと各曲点A,B,・・・の経緯度と加減算した作業圃場面積を自動制御装置の圃場データに記憶することを特徴とする圃場の自律走行作業車とする。【選択図】図6
