    摘要： A child restraint system and a method for monitoring installation of the child restraint system are provided. The child restraint system includes a child seat configured to receive a child occupant. The child seat has at least a first seat belt guide member configured to engage a vehicle seat belt webbing for securing the child seat to a vehicle seat. The child restraint system further includes a first sensor coupled to the first seat belt guide member. The first sensor is configured to output a first signal indicative of an amount of tension being applied to the vehicle seat belt webbing. The child restraint system further includes a controller coupled to the child seat configured to receive the first signal and to compute a first tension value based on the first signal. The controller further is configured to induce a first device disposed on the child seat to indicate when the first tension value is less than a predetermined tension value.

    摘要： A child restraint system for transporting a child within an automotive vehicle includes a weight sensor for determining the weight of the child and compares the child's weight to a recommended weight range. The weight sensor is disposed within a cushion that lines a shell and provides an electrical signal to a control unit. The control unit processes the electrical signal and provides an alert signal when the weight is not within the recommended range. Also, the child restraint system may include a second sensor for sensing a condition that depends upon the child's weight such as directional orientation or angular orientation of the child restraint system, or location or tension of a vehicle seat belt or tether that secures the child restraint system within the vehicle, or the location or tension of a harness for restraining the child occupant within the child restraint system.

    摘要： A child seat monitoring system for a child seat and a method for determining a type of child seat are provided. The child seat has a first region and an opposite second region. The child seat has first and second patterns disposed on the first and second regions, respectively, both indicating whether the child seat is a forward-facing child seat or a rearward-facing child seat relative to a vehicle seat. The system includes a first detection apparatus configured to detect either the first pattern on the first region of the child seat or the second pattern on the second region of the child seat. The system further includes a controller operably communicating with the first detection apparatus. The controller is configured to generate a first signal when the child seat is a forward-facing child seat.

    摘要： An improved vehicle seat occupant weight estimation method detects weight applied to both the seat cushion and the floor forward of the seat, and increases the measured seat weight of the occupant to account for occupant weight off-loaded to the floor. Fluid-filled bladders or other sensors are arranged to detect occupant seat weight and the weight applied to the vehicle floor forward of the seat. Upon opening of a vehicle door or an off-to-on transition of the vehicle ignition switch, the seat and floor weight sensors are monitored to detect the presence of an occupant. When the seat becomes occupied, or whenever there is a large change in the measured seat weight, the seat and floor weight are recorded, the occupant weight is estimated according to the recorded seat weight, and the inflatable restraints are allowed or suppressed based on the estimated occupant weight. When a sustained occupant weight shift is detected, the estimated occupant weight is increased in proportion to the amount of weight shifting, but is limited to a maximum value based on the detected floor and seat weights.

    摘要： An improved vehicle restraint system includes a seat belt tension sensor and an occupant detection control module for characterizing the occupant of a vehicle seat to determine whether to allow or suppress deployment of supplemental inflatable restraints for the occupant. The belt tension sensor includes on-board signal processing circuitry and is coupled to occupant detection control module via a two wire interface that both powers the sensor and its signal processing circuitry and supports communication of belt tension data to the occupant detection control module. The sensor produces an electrical signal responsive to seat belt tension, and the processing circuitry generates one of a specified number of messages pertaining to the range of the measured tension, and then modulates the current through the two wire interface to communicate the generated message to the occupant detection control module.

    摘要： A multiple sensor, vehicle seat occupant status determination system uses dynamic variations in occupant responsive sensor output due to accelerations of the vehicle seat to discriminate via a statistical method between sensors that are failed and those that are operating correctly and eliminates the contribution of signals detected as not valid from the status determination. If and only if the maximum and minimum sampled signal values of at least one of the received signals span upper and lower control reference values derived from the sampled signal values, a variance value for each of the signals is derived; and one or both of the greatest two or the smallest two variance values are checked against a relative size factor to detect an outlier signal value. If an outlier signal value is detected more than a predetermined number of consecutive times, the status classification is performed without signal values from the outlier sensor.
