摘要： A system for correcting seat occupant weight measurement error induced by a seat belt is used to control deployment of vehicle aribags. When a child seat (28) is secured to a vehicle seat (16) with a seat belt (20), the belt is pulled to a very tight position, which applies a greater force to the seat, erroneously raising the measured occupant weight. The subject system detects the difference between a child seat with a large seat belt force and a small adult, and modifies airbag deployment accordingly. The system includes a sensor assembly mounted within the seat bottom that measures a total seat occupant weight. A control unit generates a compensation factor based on the sensor assembly weight measurements and the mounting locations of the seat belt. The compensation factor is used to correct the total seat occupant weight, providing a modified occupant weight. Airbag deployment is controlled based on the modified occupant weight.

摘要： A vehicle weight classification system (20) recognizes the various factors that influence system performance. Some of the factors are compensated for using analog signal processing circuitry or techniques. Other factors are compensated for using digital signal processing techniques. The unique combination of analog and digital approaches, rather than pure analog or pure digital, provides an effective solution at addressing the various factors that influence signals and system performance in a vehicle weight classification system while keeping the cost and complexity of the system within acceptable limits.

摘要： A vehicle weight classification system (20) includes a method of classifying weight information. A plurality of zones (52, 54, 56, 58, 60) are defined and are associated with each of the weight classifications (44, 46, 48, 50). In one example, the upper and lower limits of the zones overlap those of an adjacent zone. The upper and lower limits of the zones preferably also overlap the thresholds of the corresponding weight classifications. Whenever weight information exists within a zone, a value for that zone is increased. The zone having the highest value is determined to be the zone where the weight information should be classified. The weight information is then classified into the classification associated with the zone having the highest value.
