Driver's Response When Take-Over Request Occurs during Automated Driving at Low Speed

低速走行時における自動運転から運転操作に戻るリクエストに対する ドライバ応答に関する研究

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. The authors 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.テストコースで渋滞時を想定し,自動運転下で表示位置と表示内容を変えたTORを発生させ,その後のドライバの状況確認行動を分析した.20名の実験参加者による結果から,「メータクラスタにおける情報表示」に比べて「車載ディスプレイにおける情報表示」の方が,TOR時のドライバの状況確認行動を有利にするが分かった.
