説明

Advancement of self-driving technology makes it possible to operate with high precision, such as maintaining a stable vehicle speed, which is difficult for the typical driver, maintaining short distances between vehicles, and reacting very quickly to changing conditions. Although, there are few studies on how the driver feels such automatic control. For example, it is not understood what level of anxiety will be felt by passengers when the vehicle parks next to a neighboring vehicle with only a few centimeters to spare, or drives at a speed that results in discomfort. In the experiment reported in this paper, two of the components (“Distance to other vehicles” and “Speed of vehicle”) were used as variables in a driving test performed using an autonomous vehicle simulator. The level of anxiety and whether or not it was acceptable were recorded for each variable using a questionnaire. A model was created for the relationship between the aforementioned variables and the sense of anxiety felt by individuals, and an “acceptable value” was computed in the form of “A distance (speed) of up to X is acceptable.”.
