Abstract

A method of performing vehicle diagnostics including receiving diagnostic information from at least one electronic module of a vehicle at a portable communication device from a telematics unit via a short-range wireless connection, storing the received diagnostic information in a memory in the portable communication device to form a recent-history vehicle database, performing a diagnostic analysis based on the recent-history vehicle database and sending the received diagnostic information from the portable communication device to an external memory to form an historic vehicle database.

Claims

1. A method of performing vehicle diagnostics, comprising:

receiving diagnostic information from at least one electronic module of a vehicle at a portable communication device from a telematics unit via a short-range wireless connection;

storing the received diagnostic information in a memory in the portable communication device to form a recent-history vehicle database;

performing a diagnostic analysis based on the recent-history vehicle database; and

sending the received diagnostic information from the portable communication device to an external memory to form an historic vehicle database.

2. The method of claim 1, further comprising:

storing the results of the analysis in the recent-history vehicle database in the portable communication device;

sending the results of the analysis from the portable communication device to the external memory; and

storing the results in the historic vehicle database.

3. The method of claim 1, wherein the receiving is responsive to a periodic request for diagnostic information from the telematics unit.

4. The method of claim 1, wherein the receiving is responsive to a periodic request for diagnostic information from the portable communication device.

5. The method of claim 1, further comprises:

sending the diagnostic information from the electronic module to a vehicle interface system via a vehicle communication network; and

sending the diagnostic information from the vehicle interface system to the portable communication device via the short-range wireless connection.

6. The method of claim 1, wherein the performing a diagnostic analysis includes:

determining if a vehicle problem is generated;

determining if a vehicle warning is generated;

determining if a user reminder is generated; and

alerting the user based on the determinations.

7. The method of claim 6, wherein the alerting is a visual display on the portable communication device.

8. The method of claim 6, wherein the alerting comprises:

generating an audio message in a text-to-speech engine in the portable communication device based on the determinations; and

emitting the audio message from the portable communication device.

9. The method of claim 1, wherein the external memory is selected from the group consisting of a memory of a personal computer, one or more databases in a call center, one or more databases in a data center, a removable memory card, and combinations thereof.

10. The method of claim 1, further comprising:

deleting oldest data from the recent-history vehicle database when the database is full.

11. The method of claim 1, further comprising:

providing at least a portion of the historic vehicle database from a data center to a vehicle service center upon request by a user.

12. A system for performing vehicle diagnostics, the system comprising:

means for receiving diagnostic information from at least one electronic module of a vehicle at a portable communication device from a telematics unit via a short-range wireless connection;

means for storing the received diagnostic information in a memory in the portable communication device to form a recent-history vehicle database;

means for performing a diagnostic analysis based on the recent-history vehicle database; and

means for sending the received diagnostic information from the portable communication device to an external memory to form an historic vehicle database.

13. The system of claim 12 further comprising;

means for storing the results of the analysis in the recent-history vehicle database in the portable communication device;

means for sending the results of the analysis from the portable communication device to the external memory; and

means for storing the results in the historic vehicle database.

14. The system of claim 12, further comprising:

means for sending the diagnostic information from the electronic module to a vehicle interface system via a vehicle communication network; and

means for sending the diagnostic information from the vehicle interface system to the portable communication device via a short-range wireless connection.

15. The system of claim 12, wherein the performing a diagnostic analysis includes:

means for determining if a vehicle problem is generated;

means for determining if a vehicle warning is generated;

means for determining if a user reminder is generated; and

means for alerting the user based on the determinations.

16. The system of claim 15, wherein the alerting comprises:

means for generating an audio message in a text-to-speech engine in the portable communication device based on the determinations; and

means for emitting the audio message from the portable communication device.

17. The system of claim 12, further comprising:

means for deleting the oldest data from the recent-history vehicle database when the database is full.

18. A computer readable medium storing a computer program comprising:

computer readable code for receiving diagnostic information from at least one electronic module of a vehicle at a portable communication device from a telematics unit via a short-range wireless connection;

computer readable code for storing the received diagnostic information in a memory in the portable communication device to form a recent-history vehicle database;

computer readable code for performing a diagnostic analysis based on the recent-history vehicle database; and

computer readable code for sending the received diagnostic information from the portable communication device to an external memory to form an historic vehicle database.

19. The medium of claim 18 further comprising:

computer readable code for storing the results of the analysis in the recent-history vehicle database in the portable communication device;

computer readable code for sending the results of the analysis from the portable communication device to the external memory; and

computer readable code for storing the results in the historic vehicle database.

20. The medium of claim 18, further comprising:

computer readable code for sending the diagnostic information from the electronic module to a vehicle interface system via a vehicle communication network; and

computer readable code for sending the diagnostic information from the vehicle interface system to the portable communication device via a short-range wireless connection.

21. The medium of claim 18, wherein the computer readable code for performing a diagnostic analysis includes:

computer readable code for determining if a vehicle problem is generated;

computer readable code for determining if a vehicle warning is generated;

computer readable code for determining if a user reminder is generated; and

computer readable code for alerting the user based on the determinations.
