PROBLEM TO BE SOLVED: To provide a driver state determination method and driver state determination device that allow a simple configuration to determine a drive ability of drivers with high accuracy by directly detecting a degree of concentration on drive operations.SOLUTION: A driver state determination device 1, which determines a drive state on the basis of drive operations of drivers, comprises: an in-vehicle CCD 5 that detects a movement in a vehicle width direction of a head of a driver; a lateral acceleration sensor 6 that detects a lateral acceleration; a storage unit 7b that stores reference amplitude A0 in the vehicle width direction of the head of the driver at the lateral acceleration at normal time; and a concentration level determination unit 7d that determines that a degree of concentration C of the driver is high as the amplitude A in the vehicle width direction of the head of the driver due to the lateral acceleration acted on the driver is smaller than the reference amplitude A0 corresponding to the lateral acceleration acted on the driver.SELECTED DRAWING: Figure 2
【課題】運転操作に対する集中度合を直接的に検出することにより、簡易な構成で運転者の運転能力を高精度に判定することができる運転者状態判定方法及びその判定装置を提供する。【解決手段】運転者による運転動作に基づいて運転状態を判定する運転者状態判定装置1において、運転者の頭部の車幅方向の移動を検出する車内CCD5と、横加速度を検出する横加速度センサ6と、通常時の横加速度による運転者の頭部の車幅方向の基準振幅A0を記憶する記憶部7bと、運転者に作用した横加速度による運転者の頭部の車幅方向の振幅Aが運転者に作用した横加速度に対応する基準振幅A0よりも小さい程、運転者の集中度合Cが高いと判定する集中度合判定部7dと、を備えた。【選択図】 図2
