운전자 생리 신호 측정 기법을 이용한 Steer-by-Wire 시스템의 Controllability 평가 방법 연구

다국어 초록 (Multilingual Abstract)

In the ISO 26262 Functional Safety Study, only the subjective rating through the Jury Test was used to assess the controllability. This study presents an objective evaluation method by applying physiological signal analysis methods. The subjects will conduct a subjective rating of the controllability according to the instructed rating scale, for conditions in which there is no torque feedback by the SFA due to a failure during cornering. The subjective rating used in this study, obtained reliability through the analysis of physiological signals during the failure. For heart rate (HR), no significant tendency was found, but skin conductivity (GSR) was analyzed using grouping methods to confirm the tendency of controllability, which was also statistically significant. Therefore in rating comfort of Lv.5 autonomous driving, GSR can be used as objective parameters.
