Abstract

Methods and devices for collecting and filtering vehicle parameter identification data. Filtering based on the parameter identification data is established during data collection and concurrently applied to the collected data stream. Various filtering modes can be used to present and analyze the collected data. Also disclosed are devices for analyzing parameter identification data and calculating diagnoses based on them.

Claims

1. A method for processing parameter identification data received from a vehicle, the method comprising:

calculating a filter parameter from at least one data value received from the vehicle;

filtering the parameter identification data using the filter parameter to produce filtered data; and

presenting the filtered data for analysis.

2. The method of claim 1, wherein the filter parameter comprises at least one of a level filter, a transition filter, a concurrent filter, a consecutive condition filter, a timed condition filter, a derivative filter, and an integral filter.

3. The method of claim 1, wherein the filter parameter comprises a plurality of conditions.

4. The method of claim 1, wherein the filter parameter includes at least one of a minimum threshold value and a maximum threshold value.

5. The method of claim 1, wherein the filter parameter includes a threshold slope.

6. The method of claim 1, wherein the filter parameter includes a threshold value and a threshold condition.

7. The method of claim 1, wherein the filter parameter includes a threshold condition and a time duration.

8. The method of claim 1, wherein the filter parameter includes a difference condition.

9. The method of claim 1, wherein the filter parameter includes an integral value.

10. The method of claim 1, wherein filtering the parameter identification data further comprises:

capturing a data stream from the vehicle; and

performing a real time filtering of the data stream.

11. The method of claim 1, wherein filtering the parameter identification data further comprises:

identifying unwanted data based on the filter parameter.

12. The method of claim 1, wherein presenting the filtered data further comprises:

determining a display range corresponding to minimum and maximum values of the filtered data; and

displaying, on the display screen, the filtered data within the display range.

13. An apparatus for processing parameter identification data received from a vehicle, the apparatus comprising:

a processor configured to calculate a filter parameter from at least one data value received from the vehicle and to filter the parameter identification data using the filter parameter to produce filtered data; and

a display screen operatively coupled to the processor and configured to present the filtered data for analysis.

14. The apparatus of claim 13, wherein the filter parameter comprises at least one of a level filter, a transition filter, a concurrent filter, a consecutive condition filter, a timed condition filter, a derivative filter, and an integral filter.

15. The apparatus of claim 13, wherein the filter parameter comprises a plurality of conditions.

16. The apparatus of claim 13, wherein the filter parameter includes at least one of a minimum threshold value and a maximum threshold value.

17. The apparatus of claim 13, wherein the filter parameter includes a threshold slope.

18. The apparatus of claim 13, wherein the filter parameter includes a threshold value and a threshold condition.

19. The apparatus of claim 13, wherein the filter parameter includes a threshold condition and a time duration.

20. The apparatus of claim 13, wherein the filter parameter includes a difference condition.

21. The apparatus of claim 13, wherein the filter parameter includes an integral value.

22. The apparatus of claim 13, wherein the processor is further configured to capture a data stream from the vehicle and to perform a real time filtering of the data stream.

23. The apparatus of claim 13, wherein the processor is further configured to identify unwanted data based on the filter parameter.

24. The apparatus of claim 13, wherein the processor is further configured to determine a display range corresponding to minimum and maximum values of the filtered data;

and the display screen is further configured to display the filtered data within the display range.

25. An apparatus for processing parameter identification data received from a vehicle, the apparatus comprising:

means for calculating a filter parameter from at least one data value received from the vehicle;

means for filtering the parameter identification data using the filter parameter to produce filtered data; and

means for presenting the filtered data for analysis.
