PROBLEM TO BE SOLVED: To make it possible to detect the arousal state of a driver, automatically output music with tempo which is required to maintain the arousal state of the driver in a good condition, and improve user-friendliness.SOLUTION: A driver's condition maintaining device of embodiment comprises: an arousal level determination part (9) which determines the arousal level of a driver; a music analysis part (19) which analyzes music data stored in storage parts (14, 16, 18) to acquire the tempo of music, and stores the tempo of the acquired music into a music feature database (23); and a music selection part (20) which selects music having tempo faster than the mental tempo of the driver on the basis of the music feature database (23) when the arousal level of the driver falls, and playbacks the selected music by a playback device (4).SELECTED DRAWING: Figure 1

    【課題】運転者の覚醒状態を検知し、運転者の覚醒状態を良好に維持するために必要なテンポの曲を自動的に出力することができ、また、使い勝手を向上させる。【解決手段】実施形態の運転者状態維持装置は、運転者の覚醒度を判定する覚醒度判定部(9)と、記憶部(14、16、18)に記憶されている楽曲データを解析して楽曲のテンポを取得し、取得した楽曲のテンポを楽曲特徴データベース(23)に記憶する楽曲解析部(19)と、運転者の覚醒度が低下したときに、前記楽曲特徴データベース(23)に基づいて運転者の精神テンポよりも速いテンポを有する楽曲を選択し、選択した楽曲を再生装置(4)により再生する楽曲選択部(20)とを備えたものである。【選択図】図1
