Abstract

A method for vehicle diagnostic knowledge delivery comprising receiving a search request from a user system and accessing a database of case records in response to the search request. Each of the case records includes a case-record number attribute, a set of vehicle-description attributes, a set of bookkeeping attributes, a set of system attributes, a set of symptom attributes, and a set of action attributes. The method further comprises searching the database of case records for a case record responsive to the search request. If a case record responsive to the search request is located, it is transmitted to the user system.

Claims

1. A method for vehicle diagnostic knowledge delivery, said method comprising:

receiving a search request from a user system;

accessing a database of case records indicative of field repair records created by service technicians for a plurality of vehicles in response to said search request, wherein each said case record includes a case-record number attribute, a set of vehicle-description attributes, a set of bookkeeping attributes, a set of system attributes, a set of symptom attributes and a set of action attributes;

searching said database of case records for a case record responsive to said search request; and

transmitting said case record responsive to said search request to said user system if said searching results in locating said case record responsive to said search request.

2. The method of claim 1 further including:

receiving a structured vehicle diagnostic record;

evaluating said structured vehicle diagnostic record for inclusion in said database of case records;

creating a new case record corresponding to said structured vehicle diagnostic record if said evaluating results in a determination that said structured vehicle diagnostic record should be included in said database of case records; and

storing said new case record in said case database.

3. The method of claim 2 wherein said evaluating is performed by a subject matter expert.

4. The method of claim 2 wherein said evaluating is automated.

5. The method of claim 2 wherein:

each said case record further includes a set of feedback attributes, a set of case summary attributes and an other-documentation attribute; and

creating said new case record includes adding a said set of feedback attributes, a said set of case summary attributes and a said other-documentation attribute to said structured vehicle diagnostic record.

6. The method of claim 1 further including:

receiving feedback about said case record from said user system;

evaluating said feedback; and

updating said case database in response to said evaluating.

7. The method of claim 6 wherein said updating includes removing said case record from said case database.

8. The method of claim 6 wherein said updating includes updating said case records.

9. The method of claim 1 wherein said set of vehicle-description attributes includes a vehicle identification number attribute, a vehicle year attribute, a vehicle line attribute, a vehicle identification number model attribute, a vehicle identification number make attribute, a vehicle identification number series attribute, a vehicle identification number body attribute, a vehicle identification number engine attribute, a vehicle identification number year attribute, a vehicle identification number plant attribute, a vehicle identification number serial attribute and a mileage attribute.

10. The method of claim 1 wherein said set of vehicle-description attributes includes:

a vehicle identification number attribute and a mileage attribute;

or

an attribute derivable from said vehicle identification number and said mileage attribute.

11. The method of claim 1 wherein said set of bookkeeping attributes includes a date authored attribute, a date edited attribute, an author/editor attribute, a bulletins attribute, a record number attribute, a case-record status attribute, a release authorizer attribute, a language attribute, a structured-record number attribute, and a number of structured-records attribute.

12. The method of claim 1 wherein said set of bookkeeping attributes includes at least one of a date authored attribute, a date edited attribute, an author/editor attribute, a bulletins attribute, a record number attribute, a case-record status attribute, a release authorizer attribute, a language attribute, a structured-record number attribute, and a number of structured-records attribute.

13. The method of claim 1 wherein said set of system attributes includes:

a service category type attribute;

or

said service category type attribute and a service category attribute;

or

said service category type attribute, said service category attribute and a service sub-category attribute.

14. The method of claim 1 wherein said set of symptom attributes includes a main symptom group attribute, a symptom attribute, a symptom detail attribute, a functional component/system attribute, a functional component/system detail attribute, a frequency attribute, an environment condition attribute, a vehicle condition attribute, a vehicle zone attribute, a diagnostic trouble code attribute, a diagnostic trouble code qualifier attribute and an additional symptom comments attribute.

15. The method of claim 1 wherein said set of symptom attributes includes a main symptom group attribute, a functional component/system attribute and a diagnostic trouble code attribute.

16. The method of claim 15 wherein said set of symptom attributes further includes at least one of a symptom attribute, a frequency attribute, an environment condition attribute, and a vehicle condition attribute.

17. The method of claim 1 wherein said set of action attributes includes an action taken attribute, a component name attribute, a component location attribute, a component piece of attribute, a component detail attribute, a labor operations attribute and an additional action comments attribute.

18. The method of claim 1 wherein said set of action attributes includes an action taken attribute and a component name attribute.

19. The method of claim 1 wherein each said case record further includes a set of feedback attributes.

20. The method of claim 19 wherein said set of feedback attributes includes a case useful counter attribute, a case correct counter attribute, and a feedback text attribute.

21. The method of claim 19 wherein said set of feedback attributes includes a feedback text attribute.

22. The method of claim 19 further comprising:

receiving feedback about said case record from said user system, wherein said feedback is included in said case record in said set of feedback attributes;
