PROBLEM TO BE SOLVED: To provide an arousal maintaining device which hardly causes a driver to feel annoyed.SOLUTION: An arousal maintaining device 1 comprises a stimulation execution unit, a velocity acquisition unit, and a control unit. The stimulation execution unit executes a stimulation process for changing a display position of a visual stimulus in a left-right direction within a driver's forward vision using a display device displaying the visual stimulus. The speed acquisition unit acquires a speed of the vehicle. The control unit executes stimulation processing when following conditions J1 and J2 are satisfied. J1: A time period during which a speed acquired by the speed acquisition unit continuously exceeds a preset threshold speed is longer than a preset reference time period. J 2: An elapsed time period since a last execution of stimulation processing by the stimulation execution unit is longer than a preset interval time period.SELECTED DRAWING: Figure 2

    【課題】ドライバに煩わしさを感じさせにくい覚醒維持装置を提供する。【解決手段】覚醒維持装置1は、刺激実行ユニットと、速度取得ユニットと、制御ユニットとを備える。刺激実行ユニットは、視覚刺激を表示する表示装置を用いて、ドライバの前方視界内で視覚刺激の表示位置を左右方向において変化させる刺激処理を実行する。速度取得ユニットは、車両の速度を取得する。制御ユニットは、以下の条件J1及びJ2が充足される場合に、刺激処理を実行する。J1:速度取得ユニットで取得した速度が予め設定された閾値速度を連続して超えている時間が、予め設定された基準時間より長い。J2:刺激実行ユニットによる刺激処理を前回実行した時点からの経過時間が、予め設定された間隔時間より長い。【選択図】図2
