PROBLEM TO BE SOLVED: To decide a driving state with high accuracy in consideration of a traveling environment of a vehicle or a habit of a driver.SOLUTION: The driving operation characteristics of a driver are calculated from control characteristics of a closed loop model of the driving operation of a driver who corrects the location of a vehicle 1 with respect to a traveling route on the basis of the detected position of the vehicle and the detection of the driving operation of the driver by a decision processing part 7, and the driving state of the driver is precisely decided so as not to be affected by a driving environment or the habit of the driver from a difference between the driving operation characteristics in a normal state and the latest driving operation characteristics.COPYRIGHT: (C)2010,JPO&INPIT【課題】自車の走行環境やドライバの日頃の癖を考慮した運転状態の精度の高い判定を行う。【解決手段】判定処理部7により、自車1の検出位置とドライバの運転操作の検出とに基づき、走行路に対して自車の位置を修正するドライバの運転操作の閉ループモデルの制御特性からドライバの運転操作特性を算出し、通常時の運転操作特性と最新の運転操作特性との差から、走行環境やドライバの日頃の癖の影響を受けないようにしてドライバの運転状態を精度よく判定する。【選択図】図1
