自動車乗員の制動時に関する感性評価と身体挙動の関係解明に向けた実験手法の提案

抄録

In recent years, autonomous driving technologies in automobiles have been actively developing. When the operation of an autonomous vehicle differs from the preferences of its occupants, there is a possibility of stress occurring, particularly with braking operations, which significantly affect ride comfort. This stress amplifies negative psychological effects such as unpleasantness and anxiety, thereby reducing the inherent value of the vehicle. Due to this, it is meaningful to examine the preferred braking patterns of passengers to understand what constitutes comfortable braking in autonomous vehicles. Therefore, this study aims to quantify the sensory evaluation of braking by automobile occupants and to classify their preferences using the Semantic Differential method questionnaire survey. Additionally, we will focus on the occupants' posture maintenance movements and examine measurement methods for body behavior during actual vehicle operation. This report proposes an experimental approach to simultaneously measure sensory evaluation and body behavior, aiming to elucidate their relationship during braking.
