AUTOMOBILE DRIVING ABILITY DETERMINATION DEVICE AND AUTOMOBILE DRIVING ABILITY DETERMINATION METHOD

PROBLEM TO BE SOLVED: To precisely determine deterioration in recognition ability and concentration power necessary for safe driving by a visual field cut-off rate at which the degree of wobble starts increasing by limiting a time when the presentation of a driving environment on a display is cut off to a prescribed rate per constant time when having a driver do virtual driving with an automobile driving simulator.SOLUTION: An automobile driving ability determination device comprises: an automobile driving simulator; and a visual field cut-off rate adjusting device that opens/cuts off video display by the automobile driving simulator at a prescribed visual field cut-off rate per unit time. The automobile driving ability determination device adjusts the visual field cut-off rate with the visual field cut-off rate adjusting device, determines critical visual field cut-off rate at which standard deviations of steering operation amount and vehicle lateral position variation width start increasing during virtual driving by the automobile driving simulator, and determines attention power and concentration power to visual field information necessary during automobile driving.SELECTED DRAWING: Figure 8 【課題】自動車運転シミュレータによる仮想運転を行わせる際、ディスプレイに運転環境の提示を遮断する時間を、一定時間あたり所定の比率に制限し、ふらつき度が増大し始める視界遮断率により、安全運転に必要な認知能力や集中力の低下を正確に判定する。【解決手段】自動車運転能力判定装置は、自動車運転シミュレータと、自動車運転シミュレータによる映像表示を、単位時間当たり所定の視界遮断率で開放／遮断する視界遮断率調整装置とを備えている。視界遮断率調整装置により視界遮断率を調整し、自動車運転シミュレータにより仮想運転を行った際、ステアリング操作量や車両横位置変動幅の標準偏差が増大し始める臨界視界遮断率を特定し、自動車運転時に必要な視覚情報に対する注意力、集中力を判定する。【選択図】 図８
