| dc.description.alternativeAbstract | Traffic accidents cause a lot of damage every year due to the negligence of drivers or pedestrians. In a sudden collision situation, the car has activated the Autonomous Emergency Braking System to avoid the competition situation. However, situations in which collisions cannot be avoided simply by Autonomous Emergency Braking (AEB) occur more often than they would otherwise. In this paper, we present a surrounding environment recognition methodology that enables accidents to be avoided through Automatic Emergency Steering (AES) in order to solve such situations. The road environment recognition method presented in this paper first defines the scenarios of possible accidents. To learn the defined scenario, proceed with the existing lane recognition [1], then vehicle recognition, simply using yolo v2 [2]. This reduces the dependence on the lane and presents a simpler method than the conventional two-step learning method. This is an autonomous driving system that pursues high-speed situational judgment, demonstrating that it shows better efficiency than conventional methods. Also, in this paper, focal loss [3] is used to solve the class imbalance between foreground and background. Present a new loss using the modulation factor for the existing cross entropy loss [4] so that we can reduce the weight of the predictable easy example and focus on the hard example. | - |
