Abstract
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.
