To output an appropriate warning sound.SOLUTION: A control unit 20 that is a sleepiness awakening control device includes: a driver analysis unit 21 for analyzing a sleepiness state and an awakening state of a driver of a vehicle; a travel sound analysis unit 22 for analyzing a travel sound of the vehicle that is heard inside of the vehicle; a travel state analysis unit 23 for analyzing a travel state of the vehicle; a frequency component specification unit 24 for specifying a frequency component of a warning sound for awakening sleepiness of the driver; and a warning sound output control unit 25 for outputting a warning sound of the frequency component specified by the frequency component specification unit 24. When the analysis results of the driver analysis unit 21 indicates that the driver is in the sleepiness state, the frequency component specification unit 24 outputs the warning sound for which the frequency component is set based on analysis results of the travel sound analysis unit 22 and analysis results of the travel state analysis unit 23.SELECTED DRAWING: Figure 1

    【課題】適切な警告音を出力すること。【解決手段】眠気覚醒制御装置である制御部20は、車両の運転者の眠気状態および覚醒状態を分析する運転者分析部21と、車両の車内において聞こえる車両の走行音を分析する走行音分析部22と、車両の走行状況を分析する走行状況分析部23と、運転者の眠気を覚醒する警告音の周波数成分を特定する周波数成分特定部24と、周波数成分特定部24が特定した周波数成分の警告音を出力させる警告音出力制御部25と、を備え、周波数成分特定部24は、運転者分析部21の分析結果が運転者が眠気状態であることを示す場合、走行音分析部22の分析結果と走行状況分析部23の分析結果とに基づいて、周波数成分を設定した警告音を出力する。【選択図】図1
