Collision detecting apparatus for detecting collision of vehicle with object, comprises chamber element, which is mounted on vehicle, and in which chamber cavity is defined

摘要

The collision detection device (1) comprises a chamber element (7), which is mounted on the vehicle, and in which a chamber cavity is defined. A pressure sensor (8) is provided, which detects the pressure inside the chamber cavity and outputs a detection signal indicating the detected pressure. A pressure increase calculating unit is provided for calculating a pressure rise in the event of collision of the vehicle due to a high frequency component of the detection signal.
