Abstract

The present disclosure generally relates to dynamic power curve throttling. In an exemplary embodiment, a computer-implemented method for enabling dynamic throttling of an engine includes graphically displaying a graph of a linear throttle line for the engine including an idle speed in revolutions per minute (RPM) and one or more operating speeds in revolutions per minute; using a graphical user interface to alter the linear throttling line into a non-linear dynamic throttling line; and generating a table based on the non-linear dynamic throttling line, the table including dynamic throttle increments that vary based on RPM and that are usable by a controller for dynamic throttling of the engine.

First claim

What is claimed is:

1. A computer-implemented method for enabling dynamic throttling of an engine, the method comprising:
graphically displaying a graph of a linear throttle line for the engine including an idle speed in revolutions per minute (RPM) and one or more operating speeds in revolutions per minute;
using a graphical user interface to alter the linear throttling line into a non-linear dynamic throttling line; and
generating a table based on the non-linear dynamic throttling line, the table including dynamic throttle increments that vary based on RPM and that are usable for dynamic throttling of the engine.

2. The method of claim 1 , wherein a control panel for the engine includes the graphical user interface including a display, and wherein the method includes:
graphically displaying the graph of the linear throttle line for the engine on the display of the graphical user interface of the control panel;
altering the linear throttling line into the non-linear dynamic throttling line by using the graphical user interface of the control panel; and
using the control panel to generate the table based on the non-linear dynamic throttling line that includes the dynamic throttle increments usable by the control panel for dynamic throttling of the engine.

3. The method of claim 1 , wherein the method includes:
graphically displaying the graph of the linear throttle line for the engine on a display of a computer;
altering the linear throttling line into the non-linear dynamic throttling line by using a graphical user interface of the computer; and
using the computer to generate the table based on the non-linear dynamic throttling line.

4. The method of claim 1 , wherein the method includes a controller using the dynamic throttle increments from the table for dynamic throttling of the engine.

5. The method of claim 4 , wherein the method includes the controller using the dynamic throttle increments from the table to thereby enable quick movement of the engine from the idle speed to an operating speed within a sweet spot of the engine and to thereafter provide a very high throttling resolution for the dynamic throttle increments after the engine is within the sweet spot.

6. The method of claim 1 , wherein using a graphical user interface to alter the linear throttling line into a non-linear dynamic throttling line includes using the graphical user interface to drag the linear throttling line from at least a first point graphically displayed along the linear throttling line.

7. The method of claim 6 , wherein the method includes using the graphical user interface to drag the altered linear throttling line from at least one or more additional points.

8. The method of claim 1 , wherein the dynamic throttling of the engine enables a user in a manually throttled operation to quickly move the engine from the idle speed to an operating speed within a sweet spot of the engine.

9. The method of claim 8 , wherein the dynamic throttling of the engine provides the user with a very high throttling resolution for the dynamic throttle increments after the engine is within the sweet spot.

10. The method of claim 1 , wherein the method includes saving the dynamic throttle increments from the table to a portable memory device and thereafter downloading the dynamic throttle increments from the portable memory device into multiple controllers.

11. A control panel for an engine, the control panel comprising a graphical user interface including a display, wherein:
the display is configured to be operable for graphically displaying a graph on the display of a linear throttle line for the engine including an idle speed in revolutions per minute (RPM) and one or more operating speeds in revolutions per minute;
the graphical user interface is configured to be useable for altering the linear throttling line into a non-linear dynamic throttling line; and
the control panel is configured to be operable for generating a table based on the non-linear dynamic throttling line, the table including dynamic throttle increments that vary based on RPM and that are usable by the control panel for dynamic throttling of the engine.

12. The control panel of claim 11 , wherein the control panel is configured to be operable for using the dynamic throttle increments from the table such that the engine is quickly movable from the idle speed to an operating speed within a sweet spot of the engine, and to thereafter provide a very high throttling resolution for the dynamic throttle increments after the engine is within the sweet spot.

13. The control panel of claim 11 , wherein the graphical user interface is configured to be usable to drag the linear throttling line from at least a first point graphically displayed along the linear throttling line on the display.

14. The control panel of claim 13 , wherein the graphical user interface is configured to be usable to drag the linear throttling line from at least one or more additional points.

15. The control panel of claim 11 , wherein the control panel is configured to be operable for saving the dynamic throttle increments from the table to a portable memory device, which said dynamic throttle increments are downloadable from the portable memory device into multiple control panels.

16. The control panel of claim 11 , wherein the control panel is configured to enable a user in a manually throttled operation to quickly move the engine from the idle speed to an operating speed within a sweet spot of the engine, and to thereafter provide a very high throttling resolution for the dynamic throttle increments after the engine is within the sweet spot.

17. A method of throttling of an engine, the method comprising:
rapidly increasing throttling of the engine by a controller from a first operating speed in revolutions per minute (RPM) to a second operating speed within or near a sweet spot of the engine when a user has pressed and held a throttle up switch;
pausing throttling of the engine by the controller when the engine has reached the second operating speed within or near the sweet spot of the engine without requiring the user to release the throttle up switch; and
after the pause of the throttling, restoring normal throttling of the engine by the controller when the user has released the throttle up switch, whereby the normal throttling includes increasing operating speed of the engine by a throttling increment for each press and release of the throttle up switch.

18. The method of claim 17 , wherein the method includes allowing the user to set or define the second operating speed within or near a sweet spot of the engine by using a user interface of the controller.

19. The method of claim 17 , wherein the method includes rapidly increasing throttling of the engine from the first operating speed to the second operating speed by large throttle increments of at least 10 RPM, 25 RPM, or more than 25 RPM.

20. The method of claim 17 , wherein the method includes increasing operating speed of the engine by 10 RPM for each press and release of the throttle up switch during normal throttling.

21. The method of claim 17 , wherein:
the first operating speed of the engine is an idle speed of 850 RPM;
the second operating speed within or near a sweet spot of the engine is 2000 RPM; and
the method includes rapidly increasing throttling of the engine from the idle speed of 850 RPM to 2000 RPM by large throttle increments of at least 10 RPM, 25 RPM, or more than 25 RPM.
