Basic Study on Transition to Manual from Highly Automated Driving (Third Report)

- Information Methods and Driver's Response -

Abstract

This driving simulator study was investigated drivers' ability to resume manual control from a level 3 automated vehicle. Participants were asked to engage in tablet task while automated driving. Take-over request (TOR) was provided to drivers at a construction site in each condition: TOR timing was set 10s/ 20s/ 30s and types of information were set auditory +visually/ +braking/ +voice/ +braking and voice. Improvement of driver perception, cognition, operation and vehicle behavior were demonstrated in each condition. However, in our experimental conditions, not all the drivers could pass the construction site without collision. Therefore, investigation of the transition strategy is required in future work.
