DRIVER ABNORMALITY DETERMINING DEVICE

To temporarily determine abnormality of a driver according to a traveling state of a vehicle.SOLUTION: A driver abnormality determining device 1 includes: a compartment line detecting device 3 which detects a compartment line L of a traffic lane in which a vehicle 2 travels; a lane deviation determining part 6 which determines a traffic lane to be maintained if the vehicle 2 does not exceed a virtual line for determining lane maintenance that is positioned closer to the lane center than the compartment line L, and which determines deviation from a traffic lane if the vehicle 2 exceeds the virtual line for determining lane maintenance; and a driver abnormality determining part 11 which temporarily determines abnormality of a driver of the vehicle 2 on the basis of a determination result from the lane deviation determining part 6.SELECTED DRAWING: Figure 1 【課題】車両の走行状況によってドライバの異常を仮判定する。【解決手段】ドライバ異常判定装置１は、車両２が走行している車線の区画線Ｌを検知する区画線検知装置３と、車両２が区画線Ｌよりも車線中央側に位置する車線維持判定用仮想線を越えていない場合に車線維持と判定し、車両２が車線維持判定用仮想線を越えている場合に車線逸脱と判定する車線逸脱判定部６と、車線逸脱判定部６の判定結果に基づいて車両２のドライバの異常を仮判定するドライバ異常判定部１１と、を備える。【選択図】図１
