WORK VEHICLE

To provide a work vehicle capable of smoothly moving to a start position of an autonomous operation travel path.SOLUTION: A work vehicle 100 comprises: a positioning device for measuring a self position of the work vehicle; a reciprocation travel path 20 comprising a topography information database for storing periphery Pe shape information of a farm field H, and setting a travel path in the farm field H, in which reciprocation travel is repeated on the travel path; and a headland travel path 22 on which the work vehicle travels along a periphery shape. When the work vehicle 100 receives a start instruction of autonomous travel when the self position of the work vehicle 100 is separated from the periphery Pe by a prescribed distance or more, the work vehicle moves automatically, to the start point P1 of the reciprocation travel path 20 along a start point automatic movement path 24, thereby the work vehicle can prevent a detection error such as detection of a levee as an obstacle, and the work vehicle can smoothly move to the start point P1 of the reciprocation travel path 20.SELECTED DRAWING: Figure 5 【課題】円滑に自動運転走行経路の開始位置まで移動できる作業車両を提供する。【解決手段】作業車両１００の自己位置を測定する測位装置と、圃場Ｈの外周Ｐｅ形状情報を格納する地形情報データベースを備え、圃場Ｈ内に走行経路を設定し、走行経路は往復走行を繰り返す往復走行経路２０と、外周形状に沿って走行する枕地走行経路２２とを備え、作業車両１００の自己位置が外周Ｐｅから所定の距離以上離れているときに、自律走行の開始指示を受信すると、開始点自動移動経路２４に沿って往復走行経路２０の開始点Ｐ１まで自動で移動することにより、畔などを障害物と誤検知して作業車両が停止するのを防止し、円滑に往復走行経路２０の開始点Ｐ１まで移動できる。【選択図】図５
