PROBLEM TO BE SOLVED: To provide a drowsiness prediction device and a drowsiness prediction system, which are capable of predicting the drowsiness of a driver highly accurately.SOLUTION: A drowsiness prediction device (1) includes drowsiness numerical value obtainment means (21) for obtaining a drowsiness numerical value representing drowsiness of a driver of a vehicle itself prediction change amount obtainment means (23) for obtaining a prediction change amount of the drowsiness numerical value in a zone the vehicle itself belongs to prediction value calculation means (23) for calculating a prediction value of the drowsiness numerical value in the zone on the basis of the drowsiness numerical value and prediction change amount. Further, the prediction change amount is a prediction change amount A1 calculated on the basis of a change in the drowsiness numerical value when the vehicle itself travels in the zone, or a prediction change amount A2 calculated statistically on the basis of change amounts of the drowsiness numerical value of plural vehicles that have traveled in the zone.COPYRIGHT: (C)2015,JPO&INPIT【課題】ドライバの眠気を高精度に予測できる眠気予測装置及び眠気予測システムを提供すること。【解決手段】自車両のドライバの眠気を表す眠気数値を取得する眠気数値取得手段(21)と、自車両が属する領域における前記眠気数値の予測変化量を取得する予測変化量取得手段(23)と、前記眠気数値及び前記予測変化量に基き、前記領域内における前記眠気数値の予測値を算出する予測値算出手段(23)と、を備え、前記予測変化量は、前記領域を自車両が走行したときの前記眠気数値の変化に基き算出された予測変化量A1、又は、前記領域を走行した複数の車両における前記眠気数値の変化量に基き統計的に算出された予測変化量A2であることを特徴とする眠気予測装置(1)。【選択図】 図1
