Abstract

An electrical assembly includes a seat, an electronic control unit, a seat sensor assembly, and a microphone. The electronic control unit may be configured to control movement of the seat. The microphone may be connected to the electronic control unit. The electronic control unit may be configured to determine, via the seat sensor assembly, a position of an occupant of the seat and/or a distance between the occupant and the microphone. The electronic control unit may be configured to modify at least one of a gain and/or a sensitivity associated with the microphone according to the position and/or the distance. The distance may be the distance between a head of said occupant and the microphone. The seat may include a seat base, a seat back, and/or a head restraint. The seat sensor assembly may be configured to provide information about a position of the seat.

First claim

What is claimed is:

1. An electrical assembly, comprising:
a seat;
an electronic control unit configured to control movement of the seat;
a seat sensor assembly; and
a microphone connected to the electronic control unit;
wherein the electronic control unit is configured to modify at least one of a gain and a sensitivity associated with the microphone according to information from the seat sensor assembly; and
the information from the seat sensor assembly includes whether the seat is facing forward, is facing rearward, or is disposed at an angle between forward and rearward.

2. The electrical assembly of claim 1 , wherein the electronic control unit is configured to determine a distance between a position of an occupant and the microphone; and
the electronic control unit is configured to modify the at least one of the gain and the sensitivity associated with the microphone according to the distance.

3. The electrical assembly of claim 1 , including a plurality of additional microphones;
wherein the seat includes a seat base, a seat back, and a head restraint; and the microphone is connected to the head restraint;
the electronic control unit is configured to determine a closest microphone of the microphone and the plurality of additional microphones that is closest to an occupant; and
the electronic control unit is configured to increase the gain and/or sensitivity of the closest microphone.

4. The electrical assembly of claim 1 , wherein the electronic control unit is configured to determine a change in seat position via the seat sensor assembly; and
the electronic control unit is configured to determine a position of an occupant according to the change in seat position.

5. The electrical assembly of claim 1 , wherein the electronic control unit includes an expected language;
the seat includes a default language; and
the electronic control unit is configured to set the expected language to the default language when the seat is connected with a vehicle associated with the electrical assembly.

6. The electrical assembly of claim 1 , wherein the seat sensor assembly includes one or more seat motor sensors.

7. The electrical assembly of claim 1 , including a biometric sensor configured to obtain heart rate information and/or respiratory information of an occupant;
wherein the electronic control unit is configured to determine a source of a voice command via the heart rate information and/or respiratory information.

8. The electrical assembly of claim 1 , wherein the seat sensor assembly includes one or more biometric sensors; and
the electronic control unit is configured to identify an occupant according to information from the one or more biometric sensors.

9. The electrical assembly of claim 1 , wherein the electronic control unit is configured to determine a position of a head and/or a mouth of an occupant of the seat according to information from the seat sensor assembly; and
the electronic control unit is configured to track movement of said mouth of said occupant to determine if said occupant or another occupant is speaking.

10. The electrical assembly of claim 1 , wherein the electronic control unit is configured to receive information from a camera of the seat sensor assembly to determine which occupant is speaking.

11. The electrical assembly of claim 1 , wherein the microphone includes a first state and a second state; and
the electronic control unit is configured to cause the microphone to change from the first state to the second state if an occupant provides a wake-up voice command.

12. The electrical assembly of claim 11 , wherein, when the microphone is in the second state, the electronic control unit is configured to receive one or more seat movement commands; and
the electronic control unit is configured to confirm that the occupant that provided the wake-up voice command also provided the one or more seat movement commands.

13. The electrical assembly of claim 12 , wherein when the microphone is in the second state, the electronic control unit is configured to move the seat according to the one or more seat movement commands.

14. The electrical assembly of claim 1 , wherein the electronic control unit is configured to increase the gain and/or sensitivity of the microphone to a greater degree when the seat is facing rearward than when the seat is facing forward.

15. The electrical assembly of claim 1 , including at least one additional seat and at least one additional microphone;
wherein the microphone is connected to the seat; and each additional microphone is connected to a respective additional seat.

16. A method of operating an electrical assembly, the method including:
providing an electronic control unit, a seat, a microphone, and a seat sensor assembly;
obtaining, via the electronic control unit, first information from the seat sensor assembly; and
modifying, via the electronic control unit, at least one of a gain and a sensitivity associated with the microphone according to the first information;
wherein the first information includes whether the seat is facing the microphone or facing away from the microphone.

17. The method of claim 16 , including:
obtaining, via the electronic control unit, second information from the microphone;
determining, via the electronic control unit and the second information, a desired movement of the seat; and
moving the seat according to the desired movement.

18. The method of claim 17 , including creating a three-dimensional model of the seat, the microphone, and an occupant;
wherein modifying at least one of the gain and the sensitivity includes (i) determining, via the first information, a position of said occupant relative to the microphone, and (ii) modifying at least one of the gain and the sensitivity according to the position; and
moving the seat according to the desired movement includes moving the seat according to (i) the desired movement and (ii) the three-dimensional model.

19. The method of claim 17 , wherein determining the desired movement of the seat includes determining a source of a voice command via a camera of the seat sensor assembly.

20. The method of claim 16 , including determining a language of a voice command and changing an expected language to the language of the voice command.
