To provide an arousal maintenance device that helps to suppressing fluctuations in a driver's arousal level and maintaining a state of relatively high arousal level.SOLUTION: An arousal maintenance device includes: a driver state monitoring part 31 for detecting at least one of a driver's actual arousal level and a predicted change in the arousal level; a voice output part 38 for providing stimulus information necessary for maintaining the arousal level for the driver; and an interaction control part 37 for changing an output content of the stimulus information output part according to the difference in the driver's arousal level based on an output of the driver state monitoring part. An intensity of stimulus is changed according to the difference in the reduced arousal level. Stimulus is given to maintain the arousal level when a monotonous driving state is detected. The individual driver is identified and an interaction scenario tailored to the driver's personal preference is selectively used to restrain the driver's discomfort.SELECTED DRAWING: Figure 1

    【課題】運転者の覚醒度の変動を抑制すると共に、覚醒度が比較的高い状態を維持するために役立つ覚醒度維持装置を提供すること。【解決手段】運転者の実際の覚醒度、および予想される覚醒度の変化の少なくとも一方を検知するドライバ状態監視部31と、前記運転者に対して覚醒度を維持するために必要な刺激情報を与える音声出力部38と、前記運転者状態監視部の出力に基づき、前記運転者の覚醒度の違いに応じて、前記刺激情報出力部の出力内容を変更する対話制御部37とを備えた。覚醒度低下の違いに応じて刺激の強さを変更する。単調な走行状態を検知した場合は覚醒度を維持するための刺激を与える。運転者個人を特定して運転者個人の嗜好に合わせた対話シナリオを選択的に使用し、運転者の不快感を抑制する。【選択図】図1
