To be capable of estimating an awakening degree of a driver with high accuracy by a suitable estimation method according to individual differences of the driver.SOLUTION: An awakening support is comprised of: a dialogue processing unit for outputting a dialogue voice in a question form and acquiring a driver's response voice for the dialogue voice; a response time measuring unit that measures a response time required for the driver to respond to the dialog voice with the response voice; a statistical value calculating unit that calculates a statistical value of the response time based on a history of the response time; and an estimation unit which derives an estimated value of the awakening degree of the driver based on the response time measured by the response time measuring unit and the statistical value calculated by the statistical value calculating unit.SELECTED DRAWING: Figure 1

    【課題】運転者の個人差に応じた好適な推定方法により、運転者の覚醒度を高精度に推定できるようにすること。【解決手段】質問形式の対話音声を出力し、前記対話音声に対する運転者の応答音声を取得する対話処理部と、前記対話音声に対して前記運転者が前記応答音声で応答する際に要する応答時間を計測する応答時間計測部と、前記応答時間の履歴に基づいて前記応答時間の統計値を算出する統計値算出部と、前記応答時間計測部によって計測された前記応答時間と、前記統計値算出部によって算出された前記統計値とに基づいて、前記運転者の覚醒度の推定値を導出する推定部と、を備える。【選択図】図1
