Abstract
Utilization of the driving simulator is useful to examine the safety of the automatic platooning by the Energy-saving ITS Technologies Project. It was confirmed that the full vehicle of 10m gap distance could stop only with brakes by the manual maneuver of the driver in emergency. However, avoidance maneuver of only brake has a risk of colliding of the following vehicle. So, the collision avoidance method by a steering is evaluated. In this paper, the avoidance maneuver response and behavior of a driver are analyzed of every gap distance of automatic platooning. Then, the driver behavior was considered also from a questionnaire.
