PROBLEM TO BE SOLVED: To provide a work vehicle that is constituted to facilitate correction of a travel route when a machine body is made to automatically travel along the travel route, by setting a standard travel route using the positioning data and setting the travel route along the standard travel route at predetermined intervals in the horizontal side of the standard travel route.SOLUTION: When a machine body is positioned in the position separated from a travel route L02 while the traveling along a standard travel route L01 is completed and the turning is made to enter the adjacent travel route L02, the position of the travel route L02 is corrected in a correction position K03 between an existing position K02 and a former past position K01 of only a predetermined time in the horizontal direction of the machine body. A steering device is automatically operated so that the machine body may travel along the travel route L02.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2016,JPO&INPIT【課題】測位データにより基準走行経路を設定し、基準走行経路の横側に所定間隔を置いて基準走行経路に沿った走行経路を設定して、走行経路に沿って機体を自動的に走行させるように構成した場合、走行経路の補正を容易に行うことができるように構成する。【解決手段】基準走行経路L01に沿っての走行を終了し旋回して隣接する走行経路L02に進入した状態において、機体が走行経路L02から離れた位置に位置していると、現在位置K02と所定時間だけ以前の過去位置K01との機体左右方向での間の補正位置K03に、走行経路L02の位置を補正する。機体が走行経路L02に沿って走行するように、ステアリング装置を自動的に操作する。【選択図】図8
