Method and system for determining weight and position of a vehicle seat occupant
First Claim
1. A method of compensating for various influences on a sensor signal that provides an indication of a weight of a seat occupant in a vehicle supplemental restraint system, comprising the steps of:
- processing the sensor signal using analog signal processing to compensate for at least one factor that influences the sensor signal; and
processing the sensor signal using digital signal processing to compensate for at least one other factor.

Abstract
A method and system for determining weight and/or position of a vehicle seat occupant to be used for controlling the reaction of a safety restraint system. A plurality of spaced weight sensors are disposed between a seating surface and seat mounting surface to provide output signals indicative of an applied weight on each sensor. The sensors are spaced such that the sensors measure the weight applied to a seat back and the seating surface. A controller calculates the weight and/or position of the seat occupant in response to the output signals of the sensors. The controller sends the weight and position of the seat occupant to the safety restraint system to be used to tailor or suppress the reaction of the safety restraint system.
