Evaluation of the receptivity of driver assistance agents to a linguistic considerate utterance during automated driving phase release

Abstract

In recent years, research and development on automated driving has been conducted at the national level in countries around the world. On the other hand, according to a survey conducted by the Dai-ichi Life Research Institute, about half of the participants were concerned about automated driving, and of those, about 70% were concerned about the reliability of automated driving. In addition, previous studies have suggested that voice notifications, instead of sound notifications, would reduce the annoyance felt by drivers when switching from automatic driving to manual driving. However, there has been no detailed discussion on the design of voice notification at the time of phase release. The purpose of this study is to improve the reliability and reduce the annoyance of automatic driving. We have proposed a driver assistance agent that speaks with consideration for linguistic considerations based on the strategy of politeness theory, which is a linguistic strategy for smoothing human relations, and evaluated the acceptability of the utterance.
