본 연구는 보조 로봇 신체(Supernumerary robotic limbs, SRLs)의 가동 범위에 따라 사용자의 신체수용감과 주변 공간에 대해 연구하였다. 가동 범위는 사용자의 상체 기준 상단과 하단으로 비교하였다. 실험결과, SRL 의 주변 공간에 대한 인식은 가동 범위에 따라 유의한 차이가 존재하였고, 신체수용감에서는 유의미한 차이가 없었다. 본 연구는 SRL 의 가동범위가 사용자의 공간 인식에 주는 영향에 과한 본 연구가 필요함을 시사한다.

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.

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.
다구찌 방법을 이용한 시트벨트의 유아용 시트 감지 장치 최적화 설계에 관한 연구

The child seat sensing unit, called ALR Switch, detects the activation of theAutomatic Locking Retractor (ALR) that allows the child seat to be secured in the car. It also sends a signal to the car, allowing the car to determine whether the child seat is installed. Applying an ALR switch to a seatbelt retractor only allows limited space and requires many design factors. In this study, an optimization design of the ALR Switch based on the Taguchi method was performed so that the ALR Switch can accurately and reliably detect the ALR operation status.
