PROBLEM TO BE SOLVED: To keep the introduction cost of such a device or a system relatively low and facilitate its (posterior) introduction into existing wheeled vehicles.SOLUTION: A doze preventing ECU 37 of a doze preventing device 12 is connected to each of ECUS 14 to 23 via a vehicle network 13 and executes processing to prevent dozes. First, an audio output of a loudspeaker 41 gives a vehicle driver a designative notice to operate one of operating switches 24 set at random. Along with this notice, the ECUS 14 to 18 supervising the designated operating switch 24 are instructed to return information on the reaction time taken until the pertinent operating switch 24 is operated. The relative seriousness of the driver's doziness is determined from the reaction time information, and each of the ECUS 14 to 23 is instructed to take a safety measure according to the determined seriousness.

    【課題】導入コストを抑え、また既存の車両に対する導入(後付け)をし易くする。【解決手段】居眠り防止装置12の居眠り防止ECU37は、車両ネットワーク13を介して各ECU14〜23に接続され、居眠り防止処理を実行する。まず、スピーカ41の音声出力により、運転者に対してランダムに設定された操作スイッチ24のいずれかを操作するように指定通知する。これと共に、指定された操作スイッチ24を統括するECU14〜18に対し、当該操作スイッチ24が操作されるまでの反応時間情報を返送するように指示する。反応時間情報から、運転者の眠気の度合いを判定し、その結果に応じて、各ECU14〜23に対して安全確保動作を実行させるように指示する。【選択図】図1
