<p>A dynamic payload monitor measures and displays payload weight for a loader vehicle by sensing the hydraulic pressure and position of the lift arm cylinders. 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 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> |
