摘要： A method implemented by a programmable controller to estimate the payload mass in a bed of a moving hauling machine. The method includes determining whether the machine is at a steady acceleration and grade, estimating transmission torque, calculating axle torque at at least one of the ground engaging elements, calculating force at said ground engaging element, determining the acceleration of the machine, calculating mass of the machine with the payload, adjusting the calculated mass of the machine with the payload based upon an estimated machine mass and rolling resistance, and providing an estimate of the mass of the payload.

摘要： A programmable controller implemented method of determining occurrence of bed loading events in a hauling machine. The method includes determining if the machine was stationary for a period, if the bed is in a loading position, other factors contributed to movement of the machine, calculating a bounce amplitude based upon a filtered machine accelerometer signal, comparing the amplitude with a constant reflecting a minimum amplitude, and identifying a loading event for an amplitude greater than the constant, if the machine has been stationary for a given period, the bed in a loading position, and no other factors caused machine movement.
