To make it possible to awake a driver out of sleepiness by more precisely determining the driver's sleepiness and controlling air conditioning in a vehicle.SOLUTION: A sleepiness determination device comprises: a storage unit that stores event definition information with which a predetermined event that influences a body temperature of a crew member of a vehicle is registered; an event detection unit for detecting occurrence of an event; a sleepiness determination unit that measures a body temperature of the crew member and determines whether or not sleepiness occurs in the crew member on the basis of variations in the body temperature in a predetermined measurement time; an air conditioning control instruction unit for generating an air conditioning control instruction depending on a result of the determination; and a transmission unit for transmitting the air conditioning control instruction to an external device. When the event is detected, the sleepiness determination unit starts measurement of the body temperature after a lapse of a predetermined time after the event detection.SELECTED DRAWING: Figure 1
【課題】より的確に運転者の眠気を判定し、車内空調を制御して運転者を眠気から覚醒させることができる。【解決手段】 車両の乗員の体温に影響を与える所定の事象が登録された事象定義情報を記憶した記憶部と、事象の発生を検知する事象検知部と、前記乗員の体温を計測し、所定の計測時間内における体温の変化に基づき前記乗員に眠気が生じているか否かを判定する眠気判定部と、前記判定結果に応じた空調制御指示を生成する空調制御指示部と、前記空調制御指示を外部装置に送信する送信部と、を備え、前記眠気判定部は、前記事象が検知されると、当該事象の検知から所定時間の経過後に前記体温の計測を開始する。【選択図】図1
