PROBLEM TO BE SOLVED: To provide a drowsy driving prevention device which outputs an alarm at a proper timing thereby preventing drowsy driving, neither requiring a face condition or biological information of a driver nor increasing operation load applied to the driver.SOLUTION: A drowsy driving prevention device (8) prevents a driver from falling asleep at the wheel, and comprises: a drowsiness level detection part (16) for detecting a drowsiness level of the driver based on drive operation of the driver and/or a behavior of a vehicle (1); an alarm output part (18) for outputting an alarm when the drowsiness level detected by the drowsiness level detection part is higher than a predetermined alarm threshold; an alarm threshold setting part (20) for setting the alarm threshold, based on drive operation and/or the behavior of the vehicle since travel start of the vehicle until passing of a predetermined learning time; and an alarm threshold correction part (22) for correcting the set alarm threshold, based on the set alarm threshold and detected drowsiness level, after setting the alarm threshold.

    【課題】ドライバの顔の状態や生体情報を必要とせず、且つ、ドライバの操作負担を増大させることなく、適切なタイミングで警報を出力してドライバの居眠り運転を防止することができる居眠り運転防止装置を提供する。【解決手段】居眠り運転防止装置(8)は、ドライバの居眠り運転を防止する居眠り運転防止装置であって、ドライバによる運転操作及び/又は車両(1)の挙動に基づきドライバの眠気レベルを検出する眠気レベル検出部(16)と、眠気レベル検出部により検出された眠気レベルが所定の警報閾値よりも高い場合に警報を出力する警報出力部(18)と、車両の走行開始後、所定の学習時間が経過するまでの間における運転操作及び/又は車両の挙動に基づいて警報閾値を設定する警報閾値設定部(20)と、警報閾値の設定後、この設定された警報閾値と検出された眠気レベルとに基づいて、設定された警報閾値を補正する警報閾値補正部(22)とを有する。【選択図】図1
