Abstract
Anticipating hazards regarding pedestrians dashing to roadways is potentially a key idea to reduce the number of pedestrian accidents in unsignalized intersections. The objective of this research is to construct a hazard-anticipatory braking assistance system for preventing pedestrian collisions in unsignalized intersections. To realize the objective, this paper mainly focuses on the modeling a reference velocity profile based on actual expert driver behavior data, and the design of an automatic braking control system to realize the reference safe velocity profile. The automatic braking control system uses an AC-servo motor. The AC-servo motor is designed to pull the brake pedal which is connected with a wire and idlers. Finally the feasibility of the proposed braking assistance system is verified by experiments using the experimental vehicle.
