    • A magnetic sensor (10), comprises at least one first coil (42) at an associated at least one first location (48) of a body of a vehicle (12) and at least one magnetic sensing element (50) operatively connected to at least one second location (52) of said body of said vehicle. The at least one first coil (42) is operatively coupled to a ferromagnetic element of a vehicle body, the at least one first (48) and at least one second (52) locations are in magnetic communication through a first portion (30) of the vehicle and through a second (32) portion of the vehicle, the first portion (30) of the vehicle comprises a portion of the body that is susceptible to deformation by a crash, the first portion (30) is distinct from the second portion (32), and at least one of the at least one first coil (42) and the at least one magnetic sensing element (50) comprises a coil of an electromagnetic device (51) selected from a motor, a solenoid, a window control motor, a seat control motor, a mirror control motor, and a door lock solenoid. At least one first signal is operatively connected to the at least one first coil, and at least one second signal is sensed from the at least one second coil, and a vehicle crash is discriminated from the at least one second signal.
    • 一种磁性传感器(10)包括在车辆(12)的车身的相关联的至少一个第一位置(48)处的至少一个第一线圈(42)和至少一个磁性传感元件(50),所述磁性传感元件可操作地连接到 所述车辆的所述车身的至少一个第二位置(52)。 所述至少一个第一线圈(42)可操作地联接到车体的铁磁元件,所述至少一个第一(48)和至少一个第二(52)位置通过第一部分(30) 所述车辆并且通过所述车辆的第二部分(32),所述车辆的所述第一部分(30)包括易于由于碰撞而变形的所述本体的一部分,所述第一部分(30)不同于所述第二部分 (32),并且所述至少一个第一线圈(42)和所述至少一个磁敏元件(50)中的至少一个包括选自电动机,螺线管,窗口控制器 马达,座椅控制马达,镜子控制马达和门锁电磁阀。 至少一个第一信号可操作地连接至至少一个第一线圈,并且至少一个第二信号从至少一个第二线圈感测,并且车辆碰撞与至少一个第二信号相区分。
