一般道レベル２運転支援時に信号交差点において適切な運転引継ぎを支援するHMIの研究

抄録

When level 2 automated driving is put to practical use on general roads, it is expected drivers have to take over driving more frequently as the road environment is more complex than on highways. Then three types of Human Machine Interfaces, HMIs, were proposed to support the smooth takeover from the automated driving. Two driving simulator experiments were conducted to evaluate them. In the experiments, 15 and 16 participants were asked to take over driving at the signalized intersection on the general road, and the results were evaluated based on the vehicle motion, the gaze of the participants, and the questionnaire. As a result, it was found the proposed HMI reduced the maximum deceleration and speeded up the takeover process.
