摘要： A method of loading a truck with material using a loader includes a step of determining a target load for a final pass. Material is loaded into a bucket of the loader in excess of the target load. Excess material is dumped from the bucket back to the pile in a controlled manner to arrive at a target load of reposed material in the bucket. The target load amount of the material in the bucket, which is less than a total amount of material originally loaded in the bucket is dumped into the truck by pitching the bucket. The bucket may be pitched to a determined pitch angle that is based upon the target load using an appropriate material curve stored on the loader. The pitch control algorithm can be calibrated by sensing the reposed weight of material in the bucket, and comparing that to an expected reposed weight, and then updating one of the material curves if there is a deviation.

摘要： A system is provided for estimating an operational parameter of a first engine, the first engine including a rotatable crankshaft. The system includes a model for estimating the operational parameter of the first engine as a function of instantaneous crankshaft speed at a plurality of angular positions of the crankshaft of the first engine. The model is developed, at least partially, based upon operational data from a second engine having a rotatable crankshaft. A sensor is operable to determine values representative of the instantaneous crankshaft speed of the first engine, at a plurality of angular positions of the crankshaft of the first engine. A modifier is operable to modify at least some of the representative values to, at least partially, calibrate out differences between the first and second engines that may cause variations in instantaneous crankshaft speed. The modified values are input to the model.
