高速運転中の足裏の踏力に関する動的JND計測

抄録

Although studies of driving assistance system are proceeding, a driving assistance is sometimes recognized as an unnecessary support to the driver. Therefore it is necessary to consider perceptual characteristics of human for an improvement of such driving assistance. In order to obtain the perceptual properties of drivers, the present authors focus on a haptic pedal system and measured the JND (just noticeable difference) to the reaction force on the pedal by utilizing driving simulator with a haptic pedal mechanism. In this paper, dynamic JND against no-static different force conditions was measured and the psychometric function was estimated through approximating on of the measured data.
