PROBLEM TO BE SOLVED: To provide a vehicle driver condition determination device for determining the degree of alertness of a vehicle driver even when acceleration is generated in a vehicle.SOLUTION: A pressure sensor 2 is arranged on a seating face of a vehicle, and a center-of-gravity point R is detected from pressure data of the pressure sensor 2. When acceleration is applied to the vehicle, that is, when the vehicle enters/leaves a curve or the vehicle accelerates/decelerates, a convergence time ΔTc until the center-of-gravity point R converges in a reference area E being a peripheral area of a certain reference center-of-gravity O is measured, and the degree of alertness of a vehicle driver is determined in accordance with the length of the convergence time ΔTc.COPYRIGHT: (C)2013,JPO&INPIT【課題】車両に加速度が発生した場合においても、車両運転者の覚醒度を判定することができる車両運転者状態判定装置を提供する。【解決手段】車両の座面に圧力センサ2を備え、圧力センサ2の圧力データから重心点Rを検出し、カーブ進入・脱出時、または加速・減速時などのように車両に加速度がかかった場合、重心点Rが、ある基準重心点Oの周辺の領域である基準領域Eに収束するまでの収束時間ΔTcを測定し、収束時間ΔTcの長さにより車両運転者の覚醒度を判定する。【選択図】 図3
