To determine the driver's status more accurately without increasing the cost of a vehicle.SOLUTION: A driver status determination device 1 includes a sunlight sensor 32 that detects light outside a vehicle, an in-vehicle camera 4 that captures a driver's face image, and an ECU 10 connected to the sunlight sensor 32 and the in-vehicle camera 4 via a communication path 5. The ECU 10 determines the driver's closed eyes based on the image capture results obtained by the in-vehicle camera 4, executes a first process to issue a warning to a cabin or to command the automatic stopping of a vehicle 100 based on the determination result, determines a first condition to be satisfied when an output value of the sunlight sensor 32 exceeds a first threshold value, and a second condition to be satisfied when the value obtained by subtracting the most recent moving average of the output value from the output value at the current time exceeds a second threshold value, respectively, and delays or inhibits the execution of the first process when both the first and second conditions are satisfied.SELECTED DRAWING: Figure 7

    【課題】車両のコストアップを招くことなく、ドライバの状態をより正確に判定する。【解決手段】ドライバ状態判定装置1は、車外の光を検出する陽光センサ32と、ドライバの顔画像を撮像する車載カメラ4と、通信経路5を介して陽光センサ32及び車載カメラ4と接続されたECU10と、を備える。ECU10は、車載カメラ4の撮像結果に基づいてドライバの閉眼を判定し、その判定結果に基づいて、車室内への警告発令又は車両100の自動停車を指令する第1処理を実行し、陽光センサ32の出力値が第1閾値を超えた場合に満足される第1条件と、現時点における出力値から該出力値の直近の移動平均を減算した値が第2閾値を超えた場合に満足される第2条件と、をそれぞれ判定し、第1条件及び第2条件が双方とも満足された場合に、第1処理の実行を遅延又は抑制する。【選択図】図7
