 note = {Safety and comfort are important for autonomous driving. As for safety, it is important to prevent accidents due to arousal level decrement. Therefore, a mechanism to increase and maintain arousal level is needed. In order to achieve comfort, the increment of the arousal should be in a comfortable state. Previously, there was an evaluation of the state during driving using EEG and heart rate variability, but no evaluation of comfortable arousal. In this research, we examined the method of detecting the state when the increment of arousal changes to a comfortable state from physiological indexes of EEG and heart rate variability. As a preliminary experiment, we measured brainwave and heart rate at the drowsiness and awakening states. Then, we performed correlation analysis between arousal index as well as the comfort index and the subjective evaluation results. As the result, our four proposed indexes are candidates of estimating comfort and arousal., Safety and comfort are important for autonomous driving.
