リスク予測型安全速度制御による交差点右折時の衝突回避システムの開発

抄録

In Japan, vehicle to vehicle collisions and vehicles to motorcycles, bicycles and pedestrians are decreasing overall, however, still high number of accidents are occurring at intersection and fatalities and injuries in intersection accidents account for a half of all traffic fatalities and injuries. Especially, the number of traffic fatalities and injuries was highest when automobiles making intersection right turn. From those statistics “intersection right turn collision avoidance system” is intensely required. Our main research objective is to develop collision avoidance system at intersection right turn without depending on C2X/X2C communication. In this paper, we focus on the situation that an object darts out from blind spot of congested oncoming vehicle at intersection right turn. In this scenario, it is difficult to avoid collision by only conventional collision avoidance system because ttc is too short. In order to avoid collision with the darting out object, we design a system called Proactive Braking System (PBS). PBS applies brake assistance to decelerate to safe speed that collision can be avoided collision by emergency braking system (EBS) before the darting out is detected. Full-vehicle simulation using IPG CarMaker® to verify the effectiveness of the proper safe speed control system.
