Abstract

A system and method for building engine calibrations for the operation of an engine. The system includes a processor that is operatively coupled to a memory. The system identifies a plurality of features, which may be stored on a memory, relating to the operation of the engine. Each of the plurality of features is associated with a feature calibration data file. A user may selected, such as via operation of an input, which features are to be used in building engine calibrations. The system may implement rules that identify which of the selected features may be combined with other selected features in creating the engine calibration build. The feature calibration files for permissible combinations of features may then be assembled and used in generating an engine calibration.

Claims

1. A system for building engine calibrations for the operation of an engine, the system comprising:

a memory;

a processor operatively coupled to the memory, the processor being configured to;

identify a plurality of features relating to the operation of the engine, each of the plurality of features having a feature calibration data file;

receive an identification of a plurality of selected features that are selected from the identified plurality of features;

implement rules to identify allowable combinations of the plurality of selected features, at least some of the plurality of features not being allowed to be combined with at least some other features of the plurality of features;

assemble at least the feature calibration data files for the allowable combinations of features; and

build the engine calibrations using at least the assembled feature calibration data files.

2. The system of claim 1, wherein the plurality of features are assigned to one or more categories of features, and wherein the processor is configured to select at least one default feature for a category of features that does not contain one or more selected features.

3. The system of claim 1, wherein the processor is configured to control the displaying of the plurality of features on a display.

4. The system of claim 3, wherein the processor is further configured to provide an indication on the display of when the build of the engine calibrations is complete.

5. The system of claim 1, further including an input operatively coupled to the processor, the input configured to allow a user to select the plurality of selected features.

6. The system of claim 5, wherein the processor is further configured to assemble, with the feature calibration data files, one or more calibration data files for one or more non-selectable features.

7. A system for building an engine calibration for the operation of an engine, the system comprising:

a memory;

an input;

a processor operatively coupled to the memory and input, the processor being configured to;

display on a display a plurality of features, each of the plurality of features being associated with a feature calibration data file;

receive instructions from the input identifying from the plurality of features a plurality of selected features;

identify which of the plurality of selected features may be combined together to provide a plurality of combined features, at least some of the plurality of features not being combinable with at least some other features of the plurality of features; and

assemble the feature calibration data files for the plurality of combined features to provide at least a portion of the engine calibration.

8. The system of claim 7, wherein the processor is further configured to review the assembled feature calibration data files.

9. The system of claim 7, wherein the processor is further configured to receive an identification, through the input, of a software to be used to run the built engine calibration on an engine control unit.

10. The system of claim 7, wherein the plurality of features are assigned to one or more categories of features, and wherein the processor is configured to select at least one default feature for a category of features that does not contain one or more selected features.

15. The method of claim 10, further including the step of saving the engine calibration on a non-transitory computer-readable storage medium.

11. A method for building an engine calibration for the operation of an engine, the system comprising:

displaying, on a display, a plurality of features relating to the operation of the engine, each of the plurality of features having a feature calibration data file;

selecting, by operation of an input, from the plurality of features a plurality of selected features;

implementing, by the processor, rules governing which of the selected features are allowed to be combined together, at least a portion of the plurality of features not being allowed to be combined with at least some other features of the plurality of features; and

assembling the feature calibration data files of at least a portion of the allowed combinations of selected features to build at least a portion of the engine calibration.

12. The method of claim 11, further including the step of displaying on the display the allowable combinations of selected features.

13. The method of claim 12, further including the selection, by operation of the input, at least one of the displayed allowable combinations of selected features to be used in the step of assembling the feature calibration data files.

14. The method of claim 13, further including the step of identifying, the use of the input, the location of the feature calibration data files.
