Zusammenfassung: | To make it possible to decrease a reduction amount in a power storage amount of a battery in a case where a tractor is caused to execute work automatically by driving an electric motor.SOLUTION: A control device 70 of a tractor 10 includes a storage device 75c in which battery temperature characteristics are stored. The control device 70 executes data acquisition processing for acquiring outdoor temperature transition data, creation processing for creating a work schedule on the basis of the outdoor temperature transition data and the battery temperature characteristics, and automatic work processing for causing the tractor 10 to execute work by driving electric motors 41-43 automatically on the basis of the work schedule. In the creation processing, the control device 70 creates the work schedule in such a manner that the time for causing the tractor 10 to execute work in the case where power consumption efficiency is high in a predetermined period is longer than the time for causing the tractor 10 to execute work in the case where power consumption efficiency is low.SELECTED DRAWING: Figure 3
【課題】電動モータを駆動させてトラクタに作業を自動で行わせる場合において、バッテリの蓄電量の減少量を少なくすることができるようにすること。【解決手段】トラクタ10の制御装置70は、バッテリ温度特性を記憶している記憶装置75cを有する。制御装置70は、外気温推移データを取得するデータ取得処理と、外気温推移データとバッテリ温度特性とを基に作業スケジュールを作成する作成処理と、作業スケジュールを基に、自動で電動モータ41~43を駆動させてトラクタ10に作業を行わせる自動作業処理とを実行する。制御装置70は、作成処理では、所定の期間内において電力消費効率の高い場合にトラクタ10に作業を行わせる時間が電力消費効率の低い場合にトラクタ10に作業を行わせる時間よりも長くなるように、作業スケジュールを作成する。【選択図】図3 |
