First Claim
Patent Images
1. A method for adjusting a sensed load of a vehicle seat weight sensing system, the method comprising the steps of:
- determining a rate of change in the sensed load; and
determining the likelihood of drift in the sensed load in response to the determined rate of change.

Abstract
A method (60) for adjusting a sensed load W(s) of a vehicle seat weight sensing system (10) includes the step (64) of determining a rate of change {dot over (W)}(t),{dot over (W)}avg in the sensed load. The method (60) also includes the step (66) of determining the likelihood of drift in the sensed load W(s) in response to the determined rate of change {dot over (W)}(t),{dot over (W)}avg.
