Zusammenfassung:	PROBLEM TO BE SOLVED: To appropriately provoke an attention of a driver by estimating a drive readiness degree related to a drive consciousness of the driver.SOLUTION: A drive consciousness estimation apparatus includes: a driver image obtainment part for obtaining a driver image produced by imaging a driver of a vehicle; a travel environment recognition part for recognizing a travel environment surrounding the vehicle; a drive readiness degree estimation part for estimating a drive readiness degree of the driver from a response of the driver to the travel environment on the basis of the driver image and the travel environment; a travel environment requirement degree estimation part for estimating, from the travel environment, a travel environment requirement degree that is an indicator relative to the drive readiness required of the driver, on the basis of the travel environment; and an attention provocation part for provoking an attention of the driver related to driving of the vehicle on the basis of a result of comparison between the drive readiness degree and the travel environment requirement degree.SELECTED DRAWING: Figure 2 【課題】運転者の運転意識に関する運転構え度を推定して運転者へ注意喚起を適切に行う。【解決手段】車両の運転者を撮像した運転者画像を取得する運転者画像取得部と、車両の周囲の走行環境を認識する走行環境認識部と、運転者画像及び走行環境に基づいて、走行環境に対する運転者の反応から運転者の運転意識に関する運転構え度を推定する運転構え度推定部と、走行環境に基づいて、走行環境から運転者に求められる運転構え度に対する指標である走行環境要求度を推定する走行環境要求度推定部と、運転構え度と走行環境要求度との比較結果に基づいて、運転者へ車両の運転に関する注意喚起を実行する注意喚起部と、を備える。【選択図】図２
