PROBLEM TO BE SOLVED: To provide a work vehicle capable of performing appropriate notification when any abnormality is detected.SOLUTION: The work vehicle includes: a running work state detection sensor group 8 that outputs a detection signal indicating the running work state； an early abnormality determination unit 61 that determines an early stage of an abnormality as an early abnormality on the basis of the detection signal and a first condition； a real abnormality determination unit 62 that determines an actual stage of the abnormality as an actual abnormality on the basis of the detection signal and a second condition that is stricter than the first condition； a first notification part 581 that notifies the early abnormality to the outside on the basis of the judgment result that it is an early abnormality； a second notification part that notifies the outside to recover the anomaly on the basis of the judgment result that it is a real abnormality； and an abnormality recovery processing unit 64 that stops traveling and working on the condition that it is determined to be an actual abnormality.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2020,JPO&INPIT【課題】作業車において何らかの異常が検出された場合に、より適切な報知が実行される技術の提供。【解決手段】走行作業状態を示す検出信号を出力する走行作業状態検出センサ群８と、検出信号と第１条件とに基づいて異常の早期段階を早期異常として判定する早期異常判定部６１と、検出信号と第１条件より厳しい第２条件とに基づいて異常の実段階を実異常として判定する実異常判定部６２と、早期異常であるとの判定結果に基づいて、早期異常を外部に報知する第１報知部５８１と、実異常であるとの判定結果に基づいて、外部に異常回復を図るための報知を行う第２報知部と、実異常であると判定されたことを条件として走行の停止及び作業の停止を行う異常回復処理部６４とを備えている。【選択図】図３
