A method implemented by a programmable controller in a hauling machine having an engine, moveable ground engaging elements, and a bed actuable by at least one hoist cylinder controlled by an operator hoist control device, determines whether the bed is empty by determining a position of the operator hoist control device, applying a gain dependent upon the position, applying an integrator over time to provide a resultant hoist figure, comparing the resultant hoist figure to a hoist minimum constant, and, if the hoist figure is less than or equal to the hoist maximum constant, concluding that the bed is empty. |
