Displacement information deriving device, occupant restraint system, vehicle, and displacement information deriving method

摘要

In order to provide a technology, relating to detection of information about displacement of a vehicle component during a vehicle collision, which is effective for improving the detection characteristics, a collision detecting device (130) which is installed in a vehicle (200) comprises a coil sensor (131) provided with a plurality of detecting sections having different distances relative to a door outer panel (12), respectively, in a direction perpendicular to the extending direction of the door outer panel (12).
