PROBLEM TO BE SOLVED: To provide an unmanned operation system in which, when work is performed by an unmanned autonomous travel work vehicle along a set route, a work end position at the time of entering a headland and a work start position outside the headland are made to be aligned.SOLUTION: Disclosed is an autonomous travel work vehicle 1 which includes； location calculation means for positioning a location of a vehicle body using a satellite positioning system； and a control device 30 for causing the vehicle body to automatically travel or work along a set traveling route R. By the control device 30, a steering device is controlled so that a vehicle body center is along with the set traveling route, the work vehicle is driven when the action center of the work vehicle is positioned at a work start location E, and the work vehicle is controlled so as to be stopped when the action center of the work vehicle is positioned at a work end position E.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2016,JPO&INPIT【課題】無人の自律走行作業車両により設定経路に沿って作業をさせるときに、枕地に入るときの作業終了位置と、枕地から出た作業開始位置が揃うようにする無人作業システムを提供しようとする。【解決手段】衛星測位システムを利用して機体の位置を測位する位置算出手段と、設定した走行経路Ｒに沿って自動的に走行及び作業をさせる制御装置３０とを備えた自律走行作業車両１において、前記制御装置３０は、機体中心が設定走行経路に沿うように操向装置を制御し、作業機の作用中心が作業開始位置Ｅに位置すると作業機を駆動し、作業機の作用中心が作業終了位置Ｅに位置すると作業機を停止するように制御する。【選択図】図３
