To properly perform predetermined work to a work subject part at a high position away from the ground in automatically traveling of a work vehicle.SOLUTION: An automatic travel system for a work vehicle comprises an inertial measurement device which acquires inclination information of a work vehicle V, and an automatic travel control unit which causes the work vehicle V to automatically travel along a target passage P. The work vehicle V includes a work device which performs predetermined work to a work subject part Za which is positioned away from the ground, and the automatic travel control unit calculates an offset amount Δp based on altitude information of a work center pw in the work device and the inclination information and controls a position of the work vehicle V with respect to the target passage P based on the offset amount Δp.SELECTED DRAWING: Figure 18 【課題】地面から離れた高い位置の作業対象部に対する所定の作業を、作業車両の自動走行で適正に行えるようにする。【解決手段】作業車両用の自動走行システムは、作業車両Ｖの傾斜情報を取得する慣性計測装置と、作業車両Ｖを目標経路Ｐに従って自動走行させる自動走行制御部とを備え、作業車両Ｖには、地面から離れて位置する作業対象部Ｚａに対して所定の作業を行う作業装置が備えられており、自動走行制御部は、作業装置における作業中心ｐｗの高度情報と傾斜情報とに基づいてオフセット量Δｐを算出し、オフセット量Δｐに基づいて目標経路Ｐに対する作業車両Ｖの位置を制御する。【選択図】図１８
