PROBLEM TO BE SOLVED: To provide a technique that allows a work vehicle to be retreated to an arbitrary retreat area quickly and with little effort even when the work vehicle is automatically traveling and performing work in an automatic traveling system for automatically traveling the work vehicle.SOLUTION: An automatic traveling system includes: a control unit for automatically traveling a work vehicle 1 based on the current position of the work vehicle measured using a satellite positioning system； and a retreat area setting unit that sets a retreat area S2. In response to an input of a retreat instruction, the control unit executes an automatic retreat process in which the work vehicle 1 is automatically traveled and retreated to the retreat area S2 set by the retreat area setting unit.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2020,JPO&INPIT【課題】作業車両を自動走行させる自動走行システムにおいて、作業車両を自動走行させて作業を行っている際であっても、その作業車両を迅速且つ少ない労力で任意の退避領域へ退避させることができる技術を提供する。【解決手段】衛星測位システムを利用して測定した作業車両の現在位置に基づいて当該作業車両１を自動走行させる制御部を備えた自動走行システムであって、退避領域Ｓ２を設定する退避領域設定部を備え、制御部が、退避指示の入力に伴って、作業車両１を自動走行させて退避領域設定部で設定された退避領域Ｓ２に退避させる自動退避処理を実行する。【選択図】図３
