Nowadays, the interest of advanced safety vehicle is increasing. As a result also research of active safety system is in progress. And, most of the active safety system was developed for the avoidance or mitigation of first crash. But, according to the recent study, secondary crash is more dangerous than first crash. So recently many vehicle company have developed secondary crash system. For the algorithm development, the simulation of vehicle crash is required. However, many vehicle dynamics analysis programs can"t simulate vehicle crash. And also programs that possible to simulate vehicle crash are not easy to develop the algorithm such as secondary crash algorithm. So, in this paper, the crash simulation environment for developing secondary crash avoidance algorithm was developed and validated.

The light gets darker from center to edge of the light source. Therefore, we can find the center of the sun using shading histogram. Moreover, we can track the exact position of the sun with the shading histogram. In this paper, we propose a new technique using image-processing of digital camera, in order to locate the position of the sun.

This paper deals with the establishment for Multi-Driver Simulation Environment. Multi-Driver Simulation is the simulation environment considering the Human Factor and driving environment like as actual road. PreScan, PC ,based Windows and Logitech’s G27 are used for establishing simulation environment. And the number of drivers can send and receive information that used for estimating vehicle’s location such as steering angle, acceleration, deceleration data using UDP communication. Furthermore, extracted OpenStreetMap data was used for including actual road information in the simulation environment. When the system has malfunctions, this study can make simulation reconstruct and analyze the causes of failure from logged data.

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.
