摘要： A time-varying signal is applied to at least one coil in magnetic communication with at least a portion of a vehicle susceptible to deformation responsive to a crash. A sense resistor in series with the at least one coil provides for detecting a current therethrough responsive to a voltage thereacross. The current is responsive to a magnetic condition affecting the magnetic field generated by the at least one coil, responsive to the reluctance of a magnetic circuit with which the at least one coil is in magnetic communication, and responsive to associated eddy currents in proximal conductive elements, responsive to the magnetic field generated by the at least one coil.

摘要： A magnetic flux is sensed within a gap at a first location between two portions of a vehicle body/structure and a signal generated responsive thereto controls an element of the vehicle, wherein the magnetic flux is responsive to a disturbance of the vehicle body/structure. In one embodiment, the first location is proximate to the A-pillar, B-pillar or C-pillar. In another embodiment, at least a portion of the magnetic flux is generated by a coil at a different second location. A gap coil is located within a gap between portions of the vehicle body/structure for generating or sensing magnetic flux. A plurality of gap coils of various orientations provide for multi-axis sensitivity. In another aspect, a magnetic crash sensing system comprises a first coil at a first location, and a plurality of magnetic sensors at a plurality of corresponding second locations.

摘要： At least one time-varying signal is applied to a plurality of coil elements in cooperative relationship with and spanning different portions of a vehicle. The coil elements generate an associated plurality of magnetic field components that interact with the vehicle. At least one detection circuit generates a detected signal responsive to signal components from the coil elements so as to provide for detecting a change in a magnetic condition of the vehicle.
