Abstract

In this study, we focused on Adaptive Cruise Control (ACC) system as a SAE level 1 automation and investigated how ACC affects driving behavior by using electro-cardiogram data and gaze behavior data. As a result of experiments on driving simulator, we have found out that drivers tend to look aside while using ACC system (i.e. distracted driving) as well as physiological index corresponding to drivers' state of being relaxed increased. On the one hand, subjective drowsiness levels showed no significant difference among driving conditions with/without ACC system. As a result of analysis of interview data, we have also found out that the number of drivers' utterance which corresponds to drivers' attention towards surrounding vehicles significantly decrease as time proceeds while using ACC system. The results indicates the risk that ACC system could cause drivers' distraction even when drivers do not feel drowsy.
