<p>A dynamic payload monitor (10) measures and displays payload weight for a loader vehicle (11) 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. The weight computation algorithms used in the dynamic payload monitor (10) is applicable to a number of work vehicles having at least one work implement linkage (12) and at least one hydraulic cylinder (14) for effecting the linkage geometry.</p> |
