ABSTRACT:
A crush sensor has a crush box and a pressure sensor. The crush box is disposed between a vehicle-door outer panel and a door inner member which make up a vehicle door, such that a pressure-receiving surface of the crush box, which has a predetermined area, is opposed to the vehicle-door outer panel, the crush box being formed in a semi-sealed state. The pressure sensor detects the internal pressure of the crush box and outputs an electrical signal proportional to a detected value. Since the pressure sensor is capable of obtaining data corresponding to the crushing speed and the amount of crush by detecting the internal pressure of the crush box, an effect equivalent to that obtained by detecting the crushing speed and the amount of crush can be obtained with a simple arrangement without directly detecting them.
