Abstract: A payload control system includes a sensor system and a force sensor system. A controller determines a calibration machine state, a calibration linkage force, and machine calibration parameters based at least in part upon the calibration machine state and the calibration linkage force. The controller also determines a loaded implement machine state, a loaded implement linkage force, and a mass of the payload based at least in part upon the machine calibration parameters, the loaded implement machine state, and the loaded implement linkage force.

Abstract: A system for determining a hydraulic seal coefficient of friction of a hydraulic cylinder includes a force sensor to provide a force signal indicative of a force of the cylinder. A controller is configured to receive a plurality of first force signals at a first load and determine a first friction force and receive a plurality of second force signals at a second load and determine a second friction force. A hydraulic seal coefficient of friction is determined based at least in part upon the first friction force and the second friction force. A method is also disclosed.
