摘要： An improved weight-based occupant characterization method reliably distinguishes between a minimum weight adult and a child seated on a booster seat. An early characterization of the seat occupant is made in an interval following a transition event such as a door opening or ignition state change that activates the occupant detection system. During this interval, an initial characterization routine monitors the seat belt tension and the raw seat pressure to identify signal values characteristic of a minimum weight adult or a child seated on a booster seat. If the indicated occupant weight during subsequent operation of the vehicle is inconsistent with the initial characterization, the initial characterization is discarded, and the seat occupancy is characterized based on the indicated occupant weight.

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 weight-based occupant characterization method reliably distinguishes between a child or small adult and a tightly cinched child seat based on a variance in the sensed occupant weight and a variance in the vehicle acceleration. The weight variance and acceleration variance are used to determine a relative or normalized variance that compensates for the effects of operating the vehicle on a rough road surface. The occupant is characterized as a child seat if the normalized variance is below a first threshold for a predetermined interval, and as a child or small adult if the normalized variation exceeds a second threshold for a predetermined interval.

摘要： An improved occupant detection system and method includes a fluid-filled polymeric seat cushion bladder defining multiple fluid-filled chambers corresponding to different areas of the seat cushion, with no fluid flow between such chambers. Fluid pressures in the various individual chambers are detected and processed to develop a weight estimation that is compensated for occupant position. The chambers are configured to detect occupant weight in at least forward, rearward, inboard and outboard regions of the bottom seat cushion. When the detected pressures are unevenly distributed and the pressure in the forward, rearward, inboard or outboard regions of the seat exceeds the average pressure by at least a predetermined amount, a composite pressure indicative of occupant weight is adjusted in a direction to bias the suppression status in favor of allowing restraint deployment, unless the occupant is forwardly positioned on a seat that is also forwardly positioned.

摘要： In a vehicle seat occupant detection system, a transponder in a seat cushion is responsive to an activating signal to generate an electromagnetic signal containing unique seat identification data. An occupant detection system module senses a seat characteristic and derives therefrom an occupant detection signal. The module further generates the transponder activating signal and receives and processes the electromagnetic signal to derive the contained seat identification data. The module determines if there is seat identification data in a dedicated memory location in rewritable, non-volatile memory and, if there is, compares it to the seat identification data from the electromagnetic signal. If they do not match, the derivation of a valid occupant detection signal is prevented. If there is no seat identification data in the dedicated memory location, the module causes the seat identification data from the electromagnetic signal to be copied to the dedicated memory location if it remains unchanged for a predetermined number of transponder activations so as to allow authorized matching of a seat cushion and 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.

摘要： An improved occupant weight detection system measures the pressure in a fluid-filled bladder disposed in or under a foam seat cushion as an indication of occupant weight, and periodically adjusts the pressure vs. occupant weight relationship to compensate for changes due to aging and usage of the foam seat cushion. The system controller develops an aging adjustment value based on a measure of the cumulative aging and usage of the seat, and uses the developed adjustment value to compensate the operation of the system. The aging adjustment value is determined primarily as a function of occupant weight and time of seat occupancy, and the compensation is achieved by using the aging adjustment value to adjust either the estimated weight, or a threshold to which the measured pressure is compared for purposes of deciding if restraint deployment should be enabled.

摘要： An improved weight-based occupant characterization method that can inexpensively and reliably distinguish between a child or small adult and a tightly cinched child seat. When the sensed weight is in a specified range that could be produced by a tightly cinched child seat, the system characterizes the occupant based on a detected variation in sensed weight during movement of the vehicle. If the variance of the sensed weight is below a threshold for a predetermined interval, the occupant is characterized as a child seat, since a tightly cinched seat belt severely restricts variance. If the variance exceeds the threshold for a predetermined interval, the occupant is characterized as a child or small adult. A correlative factor that can be used in distinguishing between a child seat and a child or small adult is determined by computing a slope reversal rate, or frequency, of the measured weight. In this case, a child seat is indicated by the combination of low variance and a high frequency, whereas a child or small adult is indicated by the combination of high variance and a low frequency. Additionally, movement of the vehicle can be detected when the variance of the sensed weight is within a predetermined range for at least a predetermined interval.

摘要： A low-cost automatic suppression apparatus allows or suppresses deployment of a low risk deployment airbag based solely on occupant seat load and seat belt tension. The seat load and belt tension parameters are detected by low-cost sensors, and an airbag control unit suppresses airbag deployment when the occupant load is below a specified load threshold or the belt tension is above a specified tension threshold, and otherwise allows airbag deployment. The sensors are preferably switch-based so that the signals provided to the airbag control unit are in the form of a differential electrical current, and only two wires are needed to interface each sensor to the airbag control unit.
