System for dynamically controlling power provided by an engine
First Claim
1. A method for controlling power provided by an engine operating with a machine, the method comprising:
- determining a first power value reflecting a predetermined first power to be provided by the engine to a component;
determining, during machine operations, at least one of a parasitic power value reflecting power received by at least one parasitic load module from the engine and an intermittent power value reflecting power received by an intermittent load module from the engine;
determining, during machine operations, a second power value reflecting a second power provided by the engine based on the parasitic power value, the intermittent power value, and the first power value; and
adjusting, during machine operations, the second power value based on changes in at least one of the parasitic power value and the intermittent power value such that the engine substantially provides the predetermined first power to the component, and adjusting the second power value such that the second power value fluctuates between a first maximum power that the engine may provide when the parasitic load module, the intermittent load module, and the machine component are receiving power from the engine and a second maximum power value that the engine may provide when the parasitic load module and the machine component are receiving power from the engine and the intermittent load module is not receiving power from the engine.

Abstract
A method and system may be provided to perform a process for controlling power provided by an engine in a machine. In an embodiment of the present invention, a process for controlling power provided by an engine operating in a machine is provided. The process may include determining a first power value reflecting a predetermined first power to be provided by the engine to a component operating in the machine and determining, during machine operations, at least one of a parasitic load power value and an intermittent power load value. A second power value may then be determined that reflects a second power provided by the engine based on the parasitic power value, the intermittent power value, and the net power value. The second power value is adjusted such that the engine substantially provides the predetermined net power to the component.

14. A method for controlling power provided by an engine included in a machine, comprising:
-
determining a net power value reflecting a predetermined net power to be provided by the engine to a machine component included in the machine;
determining a maximum amount of gross power that the engine is to provide when one or more parasitic load modules, the machine component, and one or more intermittent load modules are receiving power from the engine during machine operations;
controlling a current gross power provided by the engine during machine operations based on determined power values associated with at least one of the one or more parasitic and the intermittent load modules such that the machine component consistently receives the predetermined net power and the current gross power does not exceed the maximum amount of gross power;
determining a transient condition during machine operations that indicates extra power is required by the machine component; and
adjusting, based on the determined transient condition, the current gross power provided by the engine such that the current gross power exceeds the maximum amount of gross power for a predetermined amount of time. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method of providing engines that allow for dynamically adjustable gross power, comprising:
-
developing a plurality of engines each with similar design characteristics including a designed gross power that the respective engine is designed to provide;
providing, for each engine, software in a controller that is configured to dynamically adjust the designed gross power provided by the engine based on data reflecting an amount of power provided by the engine to at least one of one or more parasitic load modules and one or more intermittent load modules, such that the engine provides a constant net power to an output component of the engine;
providing a first engine of the plurality of engines in a first machine that requires a first net power from the output component of the first engine;
providing a second engine of the plurality of engines in a second machine that requires a second net power from the output component of the second engine, wherein the second net power is different from the first net power;
operating the first engine in the first machine such that the controller associated with the first engine controls the first engine to constantly provide the first net power at the output component of the first engine regardless of power received by at least one of a one or more parasitic load modules and one or more intermittent load modules operating in the first machine; and
operating the second engine in the second machine such that the controller associated with the second engine controls the second engine to constantly provide the second net power at the output component of the second engine regardless of power received by at least one of a one or more parasitic load modules and one or more intermittent load modules operating in the second machine.

21. A system comprising:
-
an engine configured to provide a net power to an output component of the engine;
at least one of one or more parasitic load modules that each are configured to receive parasitic power from the engine, and one or more intermittent load modules that each are configured to receive intermittent power from the engine;
a receiving component for receiving the net power from the output component; and
a controller configured to;
determine, during engine operations, a gross power provided by the engine based on the parasitic power received by the net power and at least one of the one or more parasitic load modules and the intermittent power received by the one or more intermittent load modules, and adjust, during engine operations, the gross power based on changes in at least one of the parasitic power value and the intermittent power value such that the engine provides a constant net power to the output component, wherein the controller adjusts the gross power such that the gross power fluctuates between a first maximum gross power that the engine may provide when the one or more parasitic load modules, the one or more intermittent load modules, and the system component are receiving power from the engine and a second maximum gross power that the engine may provide when the one or more parasitic load modules and the system component are receiving power and the one or more intermittent load modules are not receiving power from the engine. - View Dependent Claims (22)
