摘要： A first magnetic field generated by a first coil operatively associated with a first portion of a vehicle interacts with at least one conductive element operatively associated with or at least a part of a second portion of the vehicle so as to generate an eddy current in the conductive element, which affects the magnetic field sensed by a magnetic sensor. A conductive element operatively coupled to a portion of the vehicle susceptible to a crash, e.g. a bumper or a door, provides for sensing a crash with the signal from the magnetic sensor. In another aspect, a second magnetic field is generated in the frame of a vehicle by a second coil wherein the frame is adapted so that the reluctance of the associated magnetic circuit is responsive to a crash. Signals from the first or second coils may be used to sense the associated magnetic fields.
