Abstract

The present invention relates to the use of a power control module with a recorder for recording audio programming and accessing audio programming that is part of a vehicle entertainment system (VES) where the power control module assures the energy used by the recorder when the vehicle is off does not drain the power supply beyond a predetermined level.

Claims

1. A vehicle entertainment system (VES) located in a vehicle, comprising:

a power supply;

a power control module coupled to the power supply, where the power control module monitors the power supply and generates indications of a status of the power supply;

an audio component;

a recorder; and

a controller coupled to the power control module, the tuner, and the recorder, where the recorder is responsive to the status of the power supply when attempting to record audio programming from the audio component.

2. The VES of claim 1, where the audio component includes at least one tuner.

3. The VES of claim 1, where the VES includes a signal from the controller to the recorder that transmitted prior to starting a recording that indicates an acceptable status of the power supply generated by the power control module whereby it is acceptable for the recorder to record an audio program.

4. The VES of claim 3, where the acceptable status identifies that an energy capacity associated with the power supply exceeds a predetermined capacity required to start the vehicle.

5. The VES of claim 4, where the power supply is a battery.

6. The VES of claim 5, where the voltage threshold is eleven volts.

7. The VES of claim 1, where the recorder responds to a change in the status of the power supply generated by the power control module.

8. The VES of claim 7, where the recorder becomes inactive in response to the change in the status of the power supply that indicates a threshold for the power supply has been triggered.

9. The VES of claim 1, where the VES includes a real time clock (RTC) with one or more configurable triggers coupled to the power control module, where the activation of a configurable trigger results in at least a portion of the VES being energized.

10. The VES of claim 9, where the configurable triggers in the RTC are deactivated when a threshold in the power control module.

11. A method for operating a vehicle entertainment system (VES) located in a vehicle, the method comprising:

signaling from a real time clock (RTC) to a power control module to energize a controller;

determining at a controller a status of a power supply coupled to the power control module;

initializing a recorder in the VES if the status indicates that the power supply is able to power the recorder; and

configuring the recorder to record audio programming from an audio component of the VES.

12. The method of claim 11, where the status of the power supply further includes, determining if a threshold in the power control module has been met.

13. The method of claim 12, where configuring the recorder includes ending the recording if the status of the power supply indicates that the threshold has been met.

14. The method of claim 12, where signaling from the RTC further includes deactivating at least one trigger located in the RTC in response to the threshold being met.

15. The method of claim 12, where determining the status of the power supply further includes measuring the voltage of the power supply and comparing it to the threshold value of 11.0 volts.

16. The method of claim 11, where configuring the recorder further includes routing the signals from a tuner to the recorder.

17. A computer-readable media that contain instructions that when executed by a controller implement a method for operating a vehicle entertainment system (VES) located in a vehicle, the method comprising:

signaling from a real time clock (RTC) to a power control module to energize a controller;

determining at a controller a status of a power supply coupled to the power control module;

initializing a recorder in the VES if the status indicates that the power supply is able to power the recorder; and

configuring the recorder to record audio programming from an audio component in the VES.

18. The computer-readable media of claim 17, where determining the status of the power supply further includes determining if a threshold in the power control module has been met.

19. The computer-readable media of claim 18, where configuring the recorder includes ending the recording if the status of the power supply indicates that the threshold has been met.

20. The computer-readable media of claim 18, where signaling from the RTC further includes deactivating at least one trigger located in the RTC in response to the threshold being met.

21. The computer-readable media of claim 17, where configuring the recorder further includes routing the signals from a tuner to the recorder.
