To provide a vehicle notification device capable of accurately specifying the cause of fluctuation in wheel speed and notifying a driver of the specified cause.SOLUTION: A control unit determines that a specific fluctuation different from a normal state has occurred in wheel speed when the wheel speed satisfies a predetermined specific fluctuation occurrence condition. Based on a detection signal, the control unit acquires, as a specific fluctuation rotation angle position, a rotation angle position of the wheel relative to a predetermined reference position when the specific fluctuation has occurred. Based on the specific fluctuation rotation angle position, the control unit specifies the cause of the occurrence of the specific fluctuation, and causes a notifying device to notify information corresponding to the specified cause.SELECTED DRAWING: Figure 8
【課題】車輪速の変動を発生させる要因を正確に特定し、特定した要因を運転者に知らせることができる車両報知装置を提供する。【解決手段】制御ユニットは、車輪速が予め定められた特異変動発生条件を満たした場合に車輪速に通常時と異なる特異変動が発生したと判定し、特異変動が発生したときの車輪の所定の基準位置に対する回転角位置を特異変動回転角位置として検出信号に基いて取得し、特異変動回転角位置に基いて特異変動を発生させた要因を特定し、特定された要因に応じた情報を報知実行装置から報知させる。【選択図】図8
