Side impact crash detection system

摘要

A side impact crash sensor that operates in conjunction with displacement of a door outer panel of a vehicle door in the event of a side impact crash. The side impact crash sensor comprises a sensor housing coupled to a vehicle door member in a sectioned region of the door and a pendulum rotates around a rotating shaft secured to the sensor housing in the event of a side impact crash. The pendulum is conductive and is housed in a housing space of the sensor housing. The side impact crash sensor further comprises a detecting section including a conductive coil energized by an alternating current secured to the sensor housing. The detecting section detects a rotation operation mode of the pendulum on the basis of a change in impedance of a conductive coil which occurs in conjunction with a rotation operation of the pendulum.
