Abstract
【解決手段】自車のドライバが意識低下状態であるか否かを判定するドライバ状態判定装置において、先行車追従時における接近度に対する加速操作状態の分布について主成分分析を行い(S16)、全データを原点移動させ(S18)、かつ、ドライバの覚醒時の加速操作状態を通常走行モデルとして作成する(S20)。そして、加速操作状態の尤度、尤度平均、尤度分散及び尤度閾値の算出を行い(S22〜S26)、現在の運転操作の尤度が尤度閾値を下回るか否かの判定を行い(S28)、下回っている場合にドライバの意識低下判定を行う。このように、ドライバの覚醒時のデータをもとに尤度閾値を算出し判定を行うためドライバの操作の特徴の差異による意識低下判定の誤判定が抑制される。
