Autonomous Braking Control System for Pedestrian Collision Avoidance by Using Potential Field

Pedestrian collision avoidance in urban environments is an important active safety technology to protect vulnerable road users and realize zero-traffic-accident society. This paper focuses on the intersection right turn driving situation which drivers need to negotiate pedestrians near crosswalk region. This paper describes an autonomous collision avoidance by electric braking torque of electric vehicle. The intensity of braking maneuver is determined by the application of Potential Fields theory with considering potential hazard due to occlusions in intersection. Finally, the effectiveness of the autonomous collision avoidance system is verified by the computer simulation and driving experiments using the micro-scale electric vehicle.
