  • Payload system with center of gravity compensation
    Patent number: 8660758
    Abstract: The present disclosure is directed to a payload calculation system for use with a work implement having at least two linkage members. The payload calculation system may have at least one state sensor configured to measure a state of the at least two linkage members. The payload calculation system may also have a processing device in communication with the at least one state sensor. The processing device may account for changes in a center of gravity of each of the at least two linkage members. The processing device may also be configured to use the at least one state sensor to determine a mass of a payload moved by the work implement.
    Type: Grant
    Filed: November 30, 2007
    Date of Patent: February 25, 2014
    Assignee: Caterpillar Inc.
    Inventors: Vijayakumar Janardhan, Jeffrey Kent Berry, Brian Mintah, Everett Gene Brandt, Robert J. Price, Kevin Dwight King
  • Payload system that compensates for rotational forces
    Patent number: 7912612
    Abstract: The present disclosure is directed to a payload calculation system for use with a work implement. The payload calculation system may have a state sensor configured to measure a state of the work implement. The payload calculation system may further have a processing device configured to calculate a mass of a payload moved by the work implement. The processing device may be configured to use the measured state to compensate the calculation of the mass for centrifugal, inertial, and frictional forces of the work implement caused by the work implement rotating about a vertical pivot.
