- Abstract
- We observe and analyze the characteristics of control authority transition according to driver's NDRT type in a highly automated vehicle driving environment in this paper. We made control authority transition scenarios and performed experiments using the vehicle simulator. We experimented five tasks such as No NDRT, Conversation, Drink, Texting and Movie. We measured the time it took the driver to take control when the takeover request (TOR) occurred and analyzed the data using ANOVA and Pearson's Chi-Squared test. According to NDRT type, TOR control transition times showed significant differences. As the experiment was repeated, it was found that the transition time was significantly shortened. In the future, we will continue to study precue provision methods, methods of providing situation awareness information, and readiness management methods to further reduce transition time.
