Abstract:

L3 level automatic driving system allows the driver to leave from driving tasks temporarily within its Operational Design Domain （ODD）. When the system reaches its boundary， it issues a Take-over Request （TOR）， alerting the driver to take over the vehicle in time. In order to explore the take-over performance of drivers with different driving experience in L3 automatic driving， emergency obstacle avoidance driving scenarios with non-driving tasks and visual assistance are designed for 24 participants of different ages with significantly different driving experience to carry out the take-over experiment on the driving simulator platform. The results show that different driving experience has no significant effect on reaction time， but there is significant difference in take-over performance. Experienced drivers have a significant improvement in the metrics like maximum steering wheel Angle and standard deviation of steering wheel Angle； i.e.， experienced drivers can resume the control of the vehicle more steadily and safely. In addition， the difference between experienced and inexperienced is more significant without visual assistance.

Key words: automatic driving, take-over performance, driving experience
