Abstract:
1. A control system for determining the net power output of an engine associated with a work machine or other vehicle wherein the work machine or other vehicle includes an engine operable to provide power to at least two power-operated components, at least one of the power-operated components being a parasitic load component, said control system comprising: an electronic controller coupled to the engine; at least one sensor coupled to said controller for inputting at least one signal thereto representative of certain operating conditions of the engine; said controller being operable to determine the total output power of the engine based upon said at least one sensor signal; at least one other sensor coupled to said controller for inputting at least one signal thereto representative of the operation of the at least one parasitic load component; said controller having memory associated therewith and having data stored therein relating to the power requirements of the at least one parasitic load component when said component is in operation at a plurality of engine speeds; said controller being operable to determine the power requirements of the at least one parasitic load component based upon said at least one other sensor signal; and said controller being operable to provide an output signal representative of the difference between the total output power of the engine and the power requirements associated with the at least one parasitic load component.
