충돌회피를 위한 자율협력주행모드 변경 판단 및 제어 알고리즘 개발

Abstract

The driving mode decision algorithm of automated highway system is necessary for collision avoidance. Furthermore, the automated highway system should control the vehicle velocity during mode changing. Measuring other vehicle in front of the target vehicle using high-tech sensors is possible, but if other vehicle is far from the target vehicle, it will be impossible to measure. Moreover, those sensors suffer from the influence of an ambient environment and come up against the reliability of information. To solve these problems, we use road-vehicle information from V2I communication. We suppose that we can receive information of the road, other vehicle, and target vehicle. We suggest the algorithm that decides driving mode and control the vehicle velocity using collision risk index. Moreover, we consider driver’s reaction time. The proposed algorithm was evaluated by using MATLAB/Simulink, Prescan, and CarSim.
