Description
図1は、本実施形態に係る車両制御装置の概略構成を示した図である。図1に示すように、本実施形態に係る車両制御装置1は、脳波計測装置2と、刺激発生装置3と、メモリ4と、ECU5と、により構成される。
次に、第2の実施形態について説明する。第2の実施形態に係る車両制御装置は、刺激パラメータの選定処理において、異なるパラメータの刺激に対する刺激効果に基づいて、睡眠時に与える刺激のパラメータを選定するものであり、特に、刺激強度が同じ刺激のうち刺激効果が高い刺激のパラメータを選定するものである。このため、以下では、刺激パラメータの選定処理についてのみ説明する。
次に、第3の実施形態について説明する。第3の実施形態に係る車両制御装置は、刺激パラメータの選定処理において、異なるパラメータの刺激に対する刺激効果に基づいて、睡眠時に与える刺激のパラメータを選定するものであり、特に、刺激効果が同じ刺激のうち刺激強度の低い刺激のパラメータを選定するものである。このため、以下では、刺激パラメータの選定処理についてのみ説明する。
また、上記実施形態では、本発明に係る刺激効果予測装置を車両制御装置に搭載するものとして説明したが、例えば、睡眠室における睡眠用や医療施設における医療用などの様々な分野において、変換モデルを作成して睡眠時の刺激効果を予測し、被験者を浅い眠りの状態に維持させるものとしてもよい。
