In the development of the fully automated vehicle, the vehicle has to be controlled to reduce the fear of autonomous driving for passengers. However, the driving situation when passengers feel a sense of fear and strangeness is not clearly explained while the vehicle runs autonomously without manual operation. Therefore, we investigate the driving situation when passengers feel a sense of fear and strangeness based on the timing and magnitude of the intervention operation by using a VR simulator that replicates fully automated driving. In this paper, experiments that the automated vehicle avoids dangerous situations are conducted. A subject can operate intervention when he/she feels fear or strangeness. We analyze the relationship between the intervention operation and manual driving operation. According to the experimental results, we discuss the operating characteristics of each person and the features of the fear of an automated driving.
