PROBLEM TO BE SOLVED: To provide an automatic traveling system that facilitates properly performing automatic traveling in an inner circumference portion in a field.SOLUTION: An automatic traveling system A is provided for managing the automatic traveling of a harvesting machine 1 for harvesting crops in a field by the first harvesting traveling including the harvesting traveling in the circumference part in the field and the second harvesting traveling being performed after the first harvesting traveling. The automatic traveling system includes: an area setting unit 24 for setting the inside of a first area being an area harvested by the first harvesting traveling as a second area； an inner circumference travel path calculation unit 25 for calculating an inner circumference travel path； a traveling control unit 26 for controlling the traveling of the harvesting machine 1 so that the second harvesting traveling may be carried out by the automatic traveling based on the inner circumference travel path； a data acquisition unit 21 for acquiring field outer shape data； and a first traveling information generation unit 27 for generating first traveling information, based on the field outer shape data. Center-dividing traveling information is contained in the first traveling information.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT【課題】圃場内の内周部分における自動走行を適切に行いやすい自動走行システムを提供する。【解決手段】圃場における外周部分での収穫走行を含む第１収穫走行と、第１収穫走行の後に行われる第２収穫走行と、によって圃場の農作物を収穫する収穫機１の自動走行を管理する自動走行システムＡであって、第１収穫走行により収穫済みとなった領域である第１領域の内側を第２領域として設定する領域設定部２４と、内周走行経路を算出する内周走行経路算出部２５と、内周走行経路に基づいた自動走行によって第２収穫走行が行われるように収穫機１の走行を制御する走行制御部２６と、圃場外形データを取得するデータ取得部２１と、圃場外形データに基づいて第１走行情報を生成する第１走行情報生成部２７と、を備え、第１走行情報に中割走行情報が含まれている。【選択図】図３
