Abstract

The invention provides a method of and system for testing a telematics system in a mobile vehicle, which begin with sending at least one test command from a test center to a call center based on a test script. A test command is transmitted from the call center to the telematics unit. The test command is executed at the telematics unit and then a test response is sent from the telematics unit to the call center. Another aspect of the invention provides a computer usable medium that includes a program for testing a telematics system in a mobile vehicle.

Claims

1. A method of testing a telematics system in a mobile vehicle, comprising:

sending at least one test command to a call center based on a test script;

transmitting at least one test command from the call center to a telematics unit;

executing the test command at the telematics unit; and

sending a test response from the telematics unit to the call center.

2. The method of claim 1 wherein the at least one test command is sent from a test center to the call center.

3. The method of claim 1 wherein the at least one test command is sent from an external test user via a web portal.

4. The method of claim 1 wherein the test script comprises a plurality of serialized test commands.

5. The method of claim 1 wherein the test command is selected from the group consisting of lock a door, unlock a door, flash the lights, send global position system coordinates, check an airbag, transfer data, switch to voice, switch to data, send an identification number, configure a unit, add calling time, modify a parameter, enable a feature, disable a feature, perform a diagnostic function, perform a communications function, process a request, and perform a request.

6. The method of claim 1 further comprising:

sending the test response from the call center to one of a test center or an external test user; and

logging the test response.

7. The method of claim 1 further comprising:

determining a pass or a fail based on the test response.

8. The method of claim 1 wherein the test response is accumulated.

9. The method of claim 1 wherein a subsequent test command is sent from one of a test center or an external test user based on the test response.

10. The method of claim 1 wherein the test command is repeated a plurality of times during a predetermined time period.

11. The method of claim 10 wherein a parameter associated with the test command is varied by a predetermined amount when the test command is repeated.

12. The method of claim 1 further comprising:

determining whether the telematics unit is in a wake-up mode; and

transmitting the test command from the call center to the telematics unit based on the determination.

13. The method of claim 1 further comprising:

generating an audio signal at the call center based on the test command; and

sending the audio signal from the call center to the telematics unit in response to the test command.

14. A computer usable medium including a program for testing a telematics system in a mobile vehicle, comprising:

computer program code to send at least one test command to a call center based on a test script;

computer program code to transmit at least one test command from the call center to a telematics unit;

computer program code to execute the test command at the telematics unit; and

computer program code to send a test response from the telematics unit to the call center.

15. The computer usable medium of claim 14 further comprising:

computer program code to send the test response from the call center to one of a test center or an external test user; and

computer program code to log the test response.

16. The computer usable medium of claim 14 further comprising:

computer program code to determine a pass or a fail based on the test response.

17. The computer usable medium of claim 14 further comprising:

computer program code to determine whether the telematics unit is in a wake-up mode; and

computer program code to transmit the test command from the call center to the telematics unit based on the determination.

18. The computer usable medium of claim 14 further comprising:

computer program code to generate an audio signal at the call center based on the test command; and

computer program code to send the audio signal from the call center to the telematics unit in response to the test command.

19. A system for testing a telematics system in a mobile vehicle, comprising:

means for sending at least one test command to a call center based on a test script;

means for transmitting at least one test command from the call center to a telematics unit;

means for executing the test command at the telematics unit; and

means for sending a test response from the telematics unit to the call center.

20. The system of claim 19 further comprising:

means for sending the test response from the call center to one of a test center or an external test user; and

means for logging the test response.

21. The system of claim 19 further comprising:

means for determining a pass or a fail based on the test response.

22. The system of claim 19 further comprising:

means for determining whether the telematics unit is in a wake-up mode; and

means for transmitting the test command from the call center to the telematics unit based on the determination.

23. The system of claim 19 further comprising:

means for generating an audio signal at the call center based on the test command; and

means for sending the audio signal from the call center to the telematics unit in response to the test command.
