摘要：Auditory signals are crucial in Level 3 autonomous vehicle takeovers, complementing visual information and reducing the demand on visual attention. This study investigated the effects of different auditory warning types (auditory icon, earcon, speech, spearcon) and emergency obstacle avoidance takeover scenarios (caused by road conditions, vehicle movement, vulnerable road users) and their interactions on driver takeover behavior. Generalized Linear Mixed Models (GLMMs) were used to analyze the data of simulated driving experiments from 40 participants. The results indicate that, for emergency obstacle avoidance takeover scenarios caused by road conditions, speech warnings exhibit high perceived acceptability but low perceived urgency; whereas in situations caused by vehicle motion or vulnerable road users, the result is the opposite. Speech and earcon warnings significantly outperform auditory icon and spearcon warnings in terms of perceived satisfaction. By integrating scale and simulated driving data, we discuss the roles of different auditory warning types in various takeover scenarios. ? 2024 Copyright held by the owner/author(s).
