摘要:
PROBLEM TO BE SOLVED: To provide an occupant state determination system for detecting an arousal level (sleepiness) on the basis of an index different from a conventional one such as an occupant's secondary behavior, and a warning device for generating a warning on the basis of the detection result.SOLUTION: An occupant state determination system includes: a camera 5 for imaging an occupant; and a determination unit 6 for detecting a degree of a secondary behavior on the basis of imaging data of the camera 5 and determining a degree of arousal level. The occupant state determination system further includes: grasping sensors 2 and 3 for detecting a grasping condition of a steering wheel 1; and the determination unit 6 for determining the arousal level of the occupant on the basis of detection data of the sensors 2 and 3. A warning device 7 is operated based on the determination result of the determination unit 6.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2019,JPO&INPIT【課題】乗員の副次行動など、従来とは異なる指標に基づいて覚醒度(眠気)を検知する乗員の状態判定システムと、この検知結果に基づいて警告を発生させる警告装置する装置を提供する。【解決手段】乗員を撮影するカメラ5と、カメラ5の撮影データに基づいて副次行動の動作程度を検知し、覚醒度を判定する判定ユニット6とを有する乗員の状態判定システム。さらにステアリングホイール1の把持状況を検知する把持センサ2,3と、センサ2,3の検知データに基づいて乗員の覚醒度を判定する判定ユニット6とを有する乗員の状態判定システム。判定ユニット6の判定結果に基づいて警告器7を作動させる。【選択図】図2
