To avoid a risk that a brake operation system for emergency stop does not operate normally in automatic traveling of a work vehicle.SOLUTION: An automatic travel system enables automatic traveling of a work vehicle which is provided with an actuator for switching a brake between a braking state and a release state for releasing braking. The automatic travel system has a control part 22Fa which executes operation confirmation processing for confirming whether or not the brake operates normally by operation control of the actuator before starting automatic traveling of the work vehicle, and allows the start of automatic traveling of the work vehicle when normal operation of the brake is confirmed in the operation confirmation processing.SELECTED DRAWING: Figure 3

    【課題】作業車両の自動走行において緊急停止用のブレーキ操作系が正常に作動しない虞を回避できるようにする。【解決手段】自動走行システムは、ブレーキを制動状態と制動を解除する解除状態とに切り換えるアクチュエータを備えた作業車両の自動走行を可能にする自動走行システムである。自動走行システムは、作業車両の自動走行開始前に、アクチュエータの作動制御でブレーキが正常に動作するかを確認する動作確認処理を行い、動作確認処理においてブレーキの正常動作が確認された場合に、作業車両の自動走行の開始を許可する制御部22Faを有する。【選択図】図3
