보행자 충돌 감지를 위한 가속도 센서에 대한 연구

Pedestrian protection has recently drawn great interest for research and development. Especially, active pedestrian protection is described from a system perspective. Active pedestrian protection system is able to be divided into two parts. The first part is the sensor system, which is placed in the bumper of the car to give an early indication that an impact is occurring. The second part of the protection system comprises active hood lift system involved in two actuators or hood airbag system. In this paper, we report acceleration sensor technologies which provide the response for the impact of pedestrian and the crash detection.
