Abstract
In accordance with a preferred embodiment, a vehicle crash discrimination system (10) comprises a plurality of coil sensors (18) permanently mounted to a vehicle pillar, and a magnet 20 either mounted to a door (14) edge surface juxtaposed to the coils, or to the pillar if a suitable ferromagnetic flux collector is mounted on the door edge. The shape, size and spacing of the coils is predetermined to provide output signals in the coils responsive to the change in the magnetic field caused by movement of the door surface. The change in magnetic field is analyzed to indicate a vehicle crash.
