Abstract

The present study aims to clarify effect of display position to show message for take-over request on driver's response during automated driving at low speed. We conducted an experiment on a test track using 20 participants. The conditions of the experiment were designed to examine the take-over process of inattentive drivers engaged in an interaction with the secondary task at low speed. There were two take-over requested conditions which were system boundary condition and system failure condition. The on-board display using for the secondary task and the center display in the instrument cluster were used to show messages for the take-over request. The study found that the response time to take control during the automated driving using the on-board display and the central display was shorter than that using the central display only under both of take-over requested conditions. Also, the drivers took appropriate gaze reaction when the takeover request indicated on the on-board display rather than on the central display under both of take-over requested conditions. It is supposed that indicating the message of the take-over request on the display showing the secondary task might reduce the driver's response time and lead appropriate driver's gaze reaction during automated driving at low speed.
