PROBLEM TO BE SOLVED: To detect an abnormal state of a driver easily without using a biological information sensor.SOLUTION: A driver state detector comprises: a torque detection part for detecting a steering torque which is applied to a steering wheel by a driver of a vehicle; a feature amount extraction part for extracting a feature amount related to an abnormal state of the driver, by performing frequency analysis of the steering torque; and a state determination part for, when the abnormal state of the driver is indicated by the feature amount, determining that the driver is in the abnormal state.SELECTED DRAWING: Figure 1

    【課題】生体情報センサを用いることなく、簡易に運転者の異常状態を検出する。【解決手段】ドライバ状態検出装置は、車両の運転者によりステアリングホイールに印加されるステアリングトルクを検出するトルク検出部と、ステアリングトルクの周波数解析を行って、運転者の異常状態に関する特徴量を抽出する特徴量抽出部と、運転者が異常状態になっていることが特徴量により表されると、運転者が異常状態になっていると判定する状態判定部と、を備える。【選択図】図1
