Abstract
Recently, research and development of autonomous driving technology has been actively conducted. It is necessary to realize safe and comfortable autonomous driving functions. This study aims to elucidate the relationship between human sensibility and posture-holding behavior for braking during autonomous driving. In this paper, we classify subjects by performing cluster analysis on the results of sensory evaluation. Therefore, subjects are classified into three groups. Then the characteristics of posture-holding behavior of each group were shown and the relationship between psychology and posture-holding behavior was investigated. The tendency of posture-holding behavior and psychological evaluation for each group is shown.
