摘要： An occupant detection system and method are provided. The system includes a capacitive sensor having an electrode arranged in a seat proximate to an expected location of an occupant for sensing an occupant presence approximate thereto. The capacitive sensor is configured to provide an output indicative of the sensed occupant presence. Occupant detection circuitry processes the sensor output and determines an aging compensation value to compensate for aging characteristics of the seat. The occupant detection circuitry detects a state of occupancy based on the sensor output and the aging compensation value.

摘要： A dual-electrode occupant detection system configured to determine an occupant presence on a seat assembly. The system includes two electrodes that each generates an electric field in response to an applied excitation signal. The two electrode signals arising therefrom can be measured individually and/or combined to detect more reliably an occupant. Such a configuration advantageously avoids the added expense and complication of an electrode arrangement that relies on an underlying shield layer to reduce electrode signal degradation caused by a seat heater element.

摘要： An air bag restraint system and control system for controlling an air bag in a vehicle and compensating for ambient temperature variations. The control system includes a temperature sensor for sensing temperature of an air bag device, and an air bag controller for controlling actuation of an air bag. The controller controls restraining force produced by the air bag as a function of the sensed temperature. Accordingly, the air bag compensates to changes in temperature so as to optimize the air bag performance.

摘要： An occupant detection system, a controller for an occupant detection system and a method of detecting an occupant. The presence or absence of the occupant varies the dielectric properties of an area proximate an electrode to influence the electrical impedance of the electrode. The electrode impedance is determined by determining electrical characteristics of a filter formed by a reference impedance device and the electrode. The pole frequency and absolute attenuation of the filter are determined based on a relative ratio of the excitation signal magnitude and the electrode signal magnitude, at two distinct frequencies. A lookup table may be used to determine the pole frequency and absolute attenuation based on the relative ratio, and thereby determine an occupant presence based on the electrode impedance.

摘要： A child restraint system includes an electronic control unit having an event data recorder for storing data relating to proper adjustment or installation of the child restraint system. The control unit receives an electrical signal from one or more sensors mounted on the child seat and determines conditions of the child seat based upon the value of the property indicated by the signal. The event data recorder is configured to store the resulting data and to allow the stored data to be retrieved in response to an inquiry. Thus, in the event of a vehicle accident or other incident, the electronic control unit may be connected to an external diagnostic unit, and the relevant data may be downloaded to the diagnostic unit for evaluation.

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.
