1. A vehicle seat weight calibration system comprising:
- at least one weight sensor for determining weight on a seating surface;
at least one presence sensor for determining the presence of an occupant on the seating surface; and
a controller calibrating the at least one weight sensor based upon a determination by the at least one presence sensor that an occupant is not present on the seating surface.

Abstract
A vehicle seat weight calibration includes at least one weight sensor for determining weight on a seating surface and at least one presence sensor for determining the presence of an occupant on the seating surface. The at least one weight sensor is calibrated based upon a determination by the presence sensor that an occupant is not present on the seating surface. If it is determined that no occupant is present on the seating surface, and if the current weight indication from the weight sensor is within a predetermined value of a previously stored zero-reference weight, the current weight is stored as the new zero-reference weight.
