Abstract
An impact sensor of an active hood system includes a rear member, optical fiber sensors, a front member and membrane switch. Each of the optical fiber sensors is disposed on upper and lower portions of a front of the rear member and senses an impact force delivered from a bumper at the time of a crash with a pedestrian. The front member is disposed at the front of the rear member and has a protrusion part pressing the optical fiber sensors by the impact force delivered from the bumper at the time of the crash with the pedestrian. The membrane switch is disposed between the front member and the optical fiber sensor, divided into a plurality of regions from a left of the front member to a right thereof, and configured to sense a region which is pressed when the pedestrian crashes with the region.
