Abstract

Embodiments are provided for customizing an audio system of a vehicle. An example computing device for customization of an audio system of a vehicle includes a display configured to present a user interface, a processor, and a storage device storing instructions executable by the processor to generate the user interface for presentation via the display, and receive user input to the user interface requesting one or more adjustments to an audio system, the one or more adjustments including instructions to tune an amplifier of the vehicle by adjusting digital signal processing (DSP) settings of the amplifier. The instructions are further executable to transmit the one or more requested adjustments to a communication interface of the amplifier of the vehicle, the adjusted DSP settings being stored in the amplifier and retrievable by the computing device.

First claim

The invention claimed is:

1. A computing device for customization of an audio system of a vehicle, the computing device comprising:
a display configured to present a user interface;
a processor; and
a storage device storing instructions executable by the processor to:
generate the user interface for presentation via the display;
receive user input to the user interface requesting one or more adjustments to the audio system, the one or more adjustments including instructions to tune an amplifier of the vehicle by adjusting digital signal processing (DSP) settings of the amplifier, the user interface being presented separately from the amplifier and the display being separate from the amplifier;
responsive to identifying or receiving an indication that one or more of the requested adjustments exceed a threshold for the amplifier, present a prompt for different adjustments; and
transmit the one or more requested adjustments or the different adjustments to a communication interface of the amplifier of the vehicle via a communication link between the computing device and the amplifier, the adjusted DSP settings being stored in the amplifier and retrievable by the computing device.

2. The computing device of claim 1 , wherein the one or more adjustments comprise a first set of adjustments, the instructions being further executable to receive user input to the user interface requesting a second set of adjustments different from the first set of adjustments, and transmit the second set of adjustments to an intervening in-vehicle computing system for forwarding to the amplifier, the second set of adjustments being transmitted from the computing device to the amplifier via the in-vehicle computing system.

3. The computing device of claim 2 , wherein the first set of adjustments includes adjustments to parameters of one or more of a notch filter, image centering, reverberation, speaker delay, and a sound image indicating a perceived location of surround sound within the vehicle.

4. The computing device of claim 3 , wherein the second set of adjustments includes adjustments to one or more of bass, treble, balance, and fade of a loudspeaker output.

5. The computing device of claim 1 , wherein the instructions are further executable to receive, from the communication interface of the amplifier, the stored adjusted DSP settings responsive to a user request, the adjusted DSP settings being stored as a user profile in one or more of the computing device, the amplifier, and a remote server.

6. The computing device of claim 1 , wherein the user interface includes user interface elements that are actuatable to request continuously variable adjustments within a maximum and a minimum value for audio parameters, and wherein the requested adjustments include adjustments to a surround sound algorithm executed by the amplifier to adjust a perceived location of output audio.

7. The computing device of claim 1 , wherein the user interface includes text boxes for entering a requested value for one or more parameters of a filter applied to an audio signal, the one or more requested adjustments including the requested value for the one or more parameters of the filter.

8. The computing device of claim 1 , wherein the instructions are further executable to identify or receive from the amplifier the indication that the one or more of the requested adjustments exceed the threshold for the amplifier, and wherein the requested adjustments include adjustments to one or more of a mixing ratio between discrete and passive decoder surround signals and a modification to steering ratios and spectral characteristics of output audio.

9. An in-vehicle computing system for a vehicle, the in-vehicle computing system comprising:
a vehicle system interface communicatively connected to an amplifier of the vehicle, the amplifier connected to a plurality of loudspeakers mounted in the vehicle to drive the plurality of loudspeakers;
an external device interface communicatively connected to a mobile device that is separate from the vehicle;
a processor; and
a storage device storing instructions executable by the processor to:
receive a first input from the mobile device to perform a first set of requested adjustments to one or more associated digital signal processing (DSP) settings of the amplifier via the mobile device to tune the amplifier, the first set of requested adjustments including adjusting a first set of parameters;
receive a second input via a user interface of the in-vehicle computing system requesting a second set of adjustments, the second set of requested adjustments including adjusting a second, different set of parameters;
for each requested adjustment to an associated DSP setting, comparing that requested adjustment to an associated threshold for that associated DSP setting, and forwarding the requested adjustments to associated DSP settings that are within the associated threshold for that DSP setting to the amplifier; and
responsive to determining that one or more of the requested adjustments is not within the threshold for the associated DSP setting, not forwarding the requested adjustments to associated DSP settings that are not within the associated threshold for that DSP setting to the amplifier, transmitting a notice to the mobile device that the requested adjustments that were not within the threshold were not made, and outputting a warning to a user of the mobile device associated with the notice.

10. The in-vehicle computing system of claim 9 , wherein the in-vehicle computing system is communicatively coupled to the amplifier via a wired connection and wherein the warning includes a prompt to the user to change the one or more of the requested adjustments that are not within the threshold for the associated DSP setting.

11. The in-vehicle computing system of claim 9 , wherein the first set of parameters includes parameters for a notch filter, image centering, reverberation, reverberation types, a delay to a set of speakers, and a surround algorithm.

12. The in-vehicle computing system of claim 9 , wherein the second set of adjustments includes adjustments to control one or more of volume, tone, faders, and balance via the plurality of loudspeakers.

13. A method of tuning an amplifier using an in-vehicle computing system, the method comprising:
receiving, at a communication interface of the in-vehicle computing system, input from a device that is spatially separate from the amplifier and the in-vehicle computing system, the input including an identification of requested adjustments to one or more digital signal processing (DSP) settings of the amplifier, the requested adjustments including adjustments to spatial characteristics of a surround sound system; and
responsive to receiving the input from the device, transmitting, to the amplifier, instructions for adjusting parameters of one or more audio signals for one or more surround sound speakers in accordance with each of the requested adjustments to the one or more DSP settings.

14. The method of claim 13 , wherein the requested adjustments include adjustments to a mixing ratio between discrete and passive decoder surround signals.

15. The method of claim 13 , wherein the requested adjustments include a modification to steering ratios and spectral characteristics of output audio.

16. The method of claim 13 , wherein the surround sound system includes a plurality of vehicle speakers including a selected combination of a right side speaker, a left side speaker, a left rear speaker, and a right rear speaker.

17. The method of claim 13 , wherein
