The Study of the User Preferences of the Request Channel on Taking Over During Level-3 Automated Vehicles' Driving Process
Abstract: When a level-3 automated vehicle fails with an autonomous driving system or encounters an unmanageable traffic situation, the driver needs to control the vehicle to ensure driving safety. The transfer process is called the driving right transfer. This study uses the qualitative research of the Likert scale method. Through experiments and questionnaires, we learn the user preferences of reminder modes in the process of driving right transfer of level-3 automated vehicles. In this research, four different warning modes, including visual takeover warning, auditory takeover warning, tactile takeover warning and multi-mode takeover warning, were tested to conduct a user preference survey and research on the warning mode of driving right takeover of level-3 automated vehicles. Through research, we have concluded that visual- tactile takeover warning is the best warning method.
