| Outline of Final Research Achievements |
In Japan, 70% of the area of Japan are in the mountain regions. Smart agricultural technology for automatic steering on flat fields has been rapidly advancing. However, the auto steering accuracy is lower on slope fields than on flat fields. There is no significant effect when the accuracy drops such as for plowing, but there is a risk of damaging the crop during mid-management with there are crops in the fields. In the case of dense crops such as onions, if the running accuracy on slopes can be improved, the space between crop lines can be reduced, and the number of effective planted area can be increased, which is considered to have a great economic effect. In this study, we experimentally analyzed the cause of the decrease of accuracy on slopes and proposed a correction control method to improve the accuracy. In the experiment, the same level of accuracy was achieved as on flat fields.

| Academic Significance and Societal Importance of the Research Achievements |
日本では中山間傾斜地の割合は日本面積の７割を占める。現時点の自動操舵技術は傾斜地での作業精度は平地と比べ、低下する場合がある。傾斜地での走行精度の向上が実現できれば行間間隔を縮小することができ、有効植付株数を増やすこともできるため、経済的な効果が大きいと考えられる。本研究は傾斜地で精度を低下した原因を分析し、傾斜地での補正制御法を提案し、実験では平地と同じレベルの精度を実現した。
