<p>A dynamic payload monitor (10) measures and displays payload weight for a loader vehicle (11) operated on a slope by sensing the hydraulic pressure and position of the lift arm cylinders (14). The payload weight is computed by curve fitting the sensed cylinder pressure and position data to a second order polynomial, and then performing interpolation or extrapolation with a pair of pressure versus position reference parabolas obtained during calibration. Payload weight is corrected for errors caused by operating the loader vehicle (11) on a slope. The weight computation algorithms used in the dynamic payload monitor (10) are applicable to a number of work vehicles having at least one work implement linkage and at least one hydraulic cylinder for modifying the linkage geometry.</p> |
