    摘要: A plurality of hydrostatic weight sensors, each incorporating a fluid and a pressure sensor for sensing the pressure thereof, are incorporated in a vehicle seat to sense occupant weight, position, and stature. In one aspect, a hydrostatic weight sensor is located in the seat back and a separate hydrostatic weight sensor is located in the seat bottom. In another aspect, a plurality of laterally or longitudinally proximate hydrostatic weight sensors, or a single bladder with a plurality of chambers, is incorporated in the seat bottom to sense occupant position. In another aspect, a hydrostatic seat weight sensor is provided by forming a fluid filled cavity within a seat cushion and sensing the pressure of the fluid therein. A signal processor calculates the occupant weight, position, and stature from the respective pressure sensor output signals and controls a safety restraint system responsive thereto.

    摘要: A sensor system for a steering wheel of a vehicle includes a first sensor disposed within a first portion of the steering wheel to detect contact with a front left surface of the steering wheel. The sensor system includes a second sensor disposed within a second portion of the steering wheel separate from the first portion to detect contact with a front right surface of the steering wheel. The sensor system also includes a third sensor disposed within the steering wheel to detect contact with a rear surface of the steering wheel. The first, second and third sensors are configured to respectively detect touching of the front left surface, the front right, and the rear surface of the steering wheel by a hand or a non-hand part of an operator of the vehicle. The first, second and third sensors can be complex impedance sensors.

    摘要: A roll angular velocity sensor and an occupant sensor are operatively coupled to a processor, which provides for detecting a rollover condition responsive to a measure of roll angular velocity and controlling a safety restraint system responsive thereto, wherein a detection criteria associated with the rollover detection process is responsive to a signal from the occupant sensor. In one embodiment, a closure time is estimated from estimates or measurements of occupant velocity or acceleration, and the estimated closure time is compared with a threshold. If the estimated closure time is less than the threshold, activation of the safety restraint system is either inhibited or advanced relative to that otherwise provided by the rollover detection process alone. Otherwise, the activation may be delayed to provide additional time for the rollover detection.

    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.
