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.
Claims23
A method relating to controlling an output of a machine including an engine, the method comprising:
- setting and/or adjusting a maintain setting for the output of the machine by using at least one of a throttle up switch and a throttle down switch of a controller;
- and
- automatically controlling, by the controller, an operating speed of the engine to achieve and/or maintain the output of the machine at the maintain setting.
A control panel for an engine of a machine having an output, the control panel comprises a throttle up switch and a throttle down switch, wherein the control panel is configurable into an operational maintain/manual control mode in which the control panel is operable for:
- setting and/or adjusting a maintain setting for the output of the machine when at least one of the throttle up switch and the throttle down switch is pressed;
- and
- automatically controlling an operating speed of the engine to achieve and/or maintain the output of the machine at the maintain setting.
A control panel for an engine, the control panel comprising a throttle up switch, wherein the control panel is configured to be operable for:
- rapidly increasing throttling of the engine 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 the throttle up switch is pressed and held;
- pausing throttling of the engine when the engine has reached the second operating speed within or near the sweet spot of the engine without requiring the release of the throttle up switch;
- and
- after the pause of the throttling, restoring normal throttling of the engine when the throttle up switch has been released, 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.
A computer-implemented method for enabling dynamic throttling of an engine, the method comprising:
- graphically displaying a graph of a linear throttling line for the engine including an idle speed in revolutions per minute (RPM) and one or more operating speeds in revolutions per minute;
- and
- using a graphical user interface to alter the linear throttling line into a non-linear and/or dynamic throttling line.
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 throttling line for the engine including an idle speed in revolutions per minute (RPM) and one or more operating speeds in revolutions per minute;
- and
- the graphical user interface is configured to be useable for altering the linear throttling line into a non-linear and/or dynamic throttling line.
