Method of determining when a payload loading event is occurring in a hauling machine

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.

1. In a hauling machine having a bed adapted to haul a payload, a method, implemented by a programmable controller, of determining whether an event loading the bed is occurring, the method comprising:
determining if the machine has been stationary for a given period, determining if the bed is in a position to be loaded, determining if other factors have contributed to movement of the machine, filtering an accelerometer signal associated with movement of the machine to calculate an amplitude of bounce, and comparing the amplitude of bounce with a predetermined constant reflecting a minimum amplitude of bounce.
