Patent ID: 7082375

Claim:
A system for validating a payload weight measurement for a machine, comprising: a pressure sensor configured to generate a pressure signal indicative of an actuating fluid pressure associated with a fluid cylinder operatively coupled to a work implement of the machine; an extension sensor configured to generate an extension signal indicative of an extension of the fluid cylinder; and a controller configured to: monitor the pressure signal and the extension signal to determine a plurality of actuating fluid pressure values and corresponding extension values associated with the fluid cylinder while lifting a payload of unknown weight with the work implement; compare the plurality of actuating fluid pressure values and the corresponding extension values to at least one predetermined pressure versus extension curve; determine whether the payload lift qualifies as a valid lift for which an accurate weight value may be assigned to the payload based on the comparison of the plurality of actuating fluid pressure values and the corresponding extension values to the at least one predetermined pressure versus extension curve.
