WAKEFULNESS MAINTENANCE DEVICE, WAKEFULNESS MAINTENANCE METHOD, AND CONTROL PROGRAM

To enable a further reduction in each object person's discomfort caused by cold air for wakefulness maintenance.SOLUTION: A wakefulness maintenance device comprises a wakefulness stimulus control part 440 that generates cold air from an air conditioner 6 for generating the cold air for maintaining a driver's wakeful state, and a characteristic identification part 410 that identifies the driver's characteristics. The wakefulness stimulus control part 440 fluctuates an air stimulus condition, which is at least any one of the driver's region for application of the cold air generated from the air conditioner 6, an air volume, a temperature and a period of blast time, in accordance with the driver's characteristics identified by the characteristic identification part 410.SELECTED DRAWING: Figure 3 【課題】覚醒維持のための冷風による対象者ごとの不快感をより低減することを可能にする。【解決手段】ドライバの覚醒状態を維持するための冷風を発生する空調装置６から冷風を発生させる覚醒刺激制御部４４０と、ドライバの特性を特定する特性特定部４１０とを備え、覚醒刺激制御部４４０は、特性特定部４１０で特定するドライバの特性に応じて、空調装置６から発生させる冷風の、ドライバへ当てる部位、風量、温度、及び送風時間の少なくともいずれかである風刺激条件を変動させる。【選択図】図３
