Document Type and Number:
Japanese Patent JP2003508776
Kind Code:
A
Abstract:
A system for correcting seat occupant weight measurement error induced by a seat belt is used to control deployment of vehicle airbags. When a child seat is secured to a vehicle seat with a seat belt, 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.
