Abstract

A method for providing open access to vehicle data is disclosed. From a vehicle under service, the method receives vehicle-diagnostic data in a manufacturer-specified format at a vehicle-service tool, and converts the vehicle data in the manufacturer-specified format into vehicle data in an open format.

8. The method of claim 1, further comprising:

formulating, by the vehicle service tool, a new parameter by execution of computer-readable program instructions that perform one or more arithmetic operations on a first parameter and a second parameter within a plurality of parameters.

9. The method of claim 8,

wherein the vehicle diagnostic data in the mark-up language format comprises the plurality of parameters including the first parameter and the second parameter,

the method further comprising:

providing, using the user interface including the display, an indication of the new parameter.

10. The method of claim 1,

wherein the vehicle diagnostic data in the manufacturer-specified format includes multiple parameters without a corresponding timestamp;

the method further comprising;

associating, by the vehicle service tool, a corresponding timestamp with each of the multiple parameters,

wherein the vehicle diagnostic data in the mark-up language format includes the multiple parameters and the corresponding timestamps.

11. The method of claim 1, wherein converting the vehicle diagnostic data in the closed format into vehicle diagnostic data in the mark-up language format comprises automatically converting the vehicle diagnostic data in the closed format into the vehicle diagnostic data in the mark-up language format in response to converting the vehicle diagnostic data in the manufacturer-specified format into the vehicle diagnostic data in the closed format.

12. The method of claim 1, wherein converting the vehicle diagnostic data in the closed format into vehicle diagnostic data in the mark-up language format occurs in response to receiving from the user interface an instruction to convert the vehicle diagnostic data in the closed format into the vehicle diagnostic data in the mark-up language format.

13. The method of claim 1, further comprising:

storing the computer-readable program instructions within a data storage device of the vehicle service tool,

wherein execution of the computer-readable program instructions occurs using a processor of the vehicle service tool.

14. The method of claim 1, further comprising:

providing, by the user interface including the display, an indication of the new parameter.

15. The method of claim 14, further comprising:

providing a graphical indication of new parameters, wherein the new parameters comprise the new parameter based on the first parameter and the second parameter and multiple other parameters, wherein each of the multiple other parameters is formulated based on a respective other instance of the first parameter and a respective other instance of the second parameter.

16. The method of claim 15, wherein each first parameter and second parameter pair upon which each new parameter is based correspond to a common sample time.

17. The method of claim 1,

wherein the vehicle diagnostic data in the mark-up language format comprises a plurality of parameters including a first parameter and a second parameter,

the method further comprising:

determining a correlation between the first parameter and the second parameter in the plurality of parameters; and

displaying a representation of the correlation between the first parameter and the second parameter.

18. The method of claim 1, wherein the vehicle diagnostic data in the manufacturer-specified format is arranged according to a Society of Automotive Engineers (SAE) standard or an International Organization for Standardization (ISO) standard.

32. The method of claim 8, wherein formulating the new parameter comprises scaling the first parameter and the second parameter to a common range or unit of measurement.
