自動運転システムの能力限界時におけるドライバ運転行動

抄録

When The aim of this study was to investigate effects of different methods of handing control back to drivers on drivers' performance. A driving simulator with thirty-six participants was used for this. The following tree methods were evaluated; ( Method A) handing all control of driving back to the drivers immediately after the limits of system functioning were reached caused by heavy fog, (Method B) continuing automated driving at a less accurate level by using facilities unaffected by heavy fog, (Method C) decreasing vehicle speeds in addition to Method B. Results showed that there was a possibility that compared to Method A drivers could resume control safely and drive more smoothly with Method B and C. Potential implication on system design of automated driving will be discussed in response to differences in the taking-over methods.
