2차 충돌 예방을 위한 충돌 후 차량 안정성 확보에 관한 연구

Traffic statistics have shown secondary or multiple event causes fatal injuries more than single event. In this paper, the Secondary Collision Mitigation Algorithm is developed for securing of vehicle stability after impacts. For appropriate control the target yaw rate is created to minimize heading angle and lateral deviation through overlay torque of MDPS and differential braking with ESC module. Impact forces are predicted by 3DOF Collision Model to reconstruct traffic accidents, and these are adopted as CarSim external forces. The performance verification of proposed algorithm is conducted SILS with CarSim.
