Research on Design of Auditory Cues for Passive Control Switch for Level 3 Automated Vehicles

When some special situations occur in L3 autonomous vehicles, the system needs to prompt the driver to take over in an appropriate way. Firstly, set the dynamic control right cutting scene as general warning, important warning and emergency warning; secondly, according to the sound attributes, the auditory prompts are divided into three categories: Auditory icon, Earcon and Voice prompts, and 9 types of auditory prompts are designed; The SCANeRTMstudio real-time vehicle dynamics simulation system performs simulation experiments on three types of switching scenarios to obtain the driver's psychological indicators and action indicators; finally, the use of analytic hierarchy process to determine the index weights, the psychological indicators and action indicators are transformed and weighted to build hearing Prompt evaluation system to determine the optimal auditory prompt method in each scenario.
