Abstract

A wireless network arrangement for a vehicle includes an electronic controller disposed within the vehicle. A plurality of wireless electronic components are disposed within the vehicle and are wirelessly communicatively coupled to the electronic controller. The components are networked together wirelessly such that members of any subgroup of the components can wirelessly communicate with each other.

Claims

1. A wireless network arrangement for a vehicle, comprising:

an electronic controller disposed within the vehicle; and

a plurality of wireless electronic components disposed within the vehicle and wirelessly communicatively coupled to the electronic controller, the components being networked together wirelessly such that members of any subgroup of the components can wirelessly communicate with each other.

2. The arrangement of claim 1 wherein each of the components includes a respective microcontroller configured to function as a wireless gateway.

3. The arrangement of claim 1 wherein the electronic controller includes a microcontroller configured to function as a wireless gateway.

4. The arrangement of claim 1 further comprising at least one movable part of the vehicle, at least one of the electronic components being attached to the at least one movable part.

5. The arrangement of claim 4 wherein the movable part comprises a steering wheel, the wireless electronic components including at least one pushbutton attached to the steering wheel.

6. The arrangement of claim 5, further comprising a display connected to the controller, the display being configured to provide feedback to a user during programming of the at least one pushbutton by the user.

7. The arrangement of claim 6 wherein the at least one pushbutton comprises a plurality of pushbuttons, the display being configured to display mappings between the pushbuttons and the programmed functions of the pushbuttons.

8. A network arrangement for a vehicle, the arrangement comprising:

a steering wheel disposed within the vehicle;

a plurality of electronic pushbuttons attached to the steering wheel; and

an electronic controller disposed within the vehicle and wirelessly communicatively coupled to the electronic pushbuttons, the controller being configured to;

receive a plurality of signals from the pushbuttons, the signals resulting from manual actuation of the pushbuttons in a coded sequence; and

program a function of at least one of the pushbuttons based on the received signals.

9. The arrangement of claim 8 wherein each of the pushbuttons includes a respective microcontroller configured to function as a wireless gateway.

10. The arrangement of claim 9 wherein the wireless gateway is configured to translate protocol between wired and wireless domains.

11. The arrangement of claim 8 wherein the electronic controller includes a microcontroller configured to function as a wireless gateway.

12. The arrangement of claim 8, further comprising a display connected to the controller, the display being configured to provide feedback to a user during programming of the pushbuttons.

13. The arrangement of claim 12 wherein the display is configured to display mappings between the pushbuttons and the programmed functions of the pushbuttons.

14. An automotive networking method, comprising:

providing a steering wheel disposed within a vehicle;

attaching a plurality of electronic pushbuttons to the steering wheel;

providing an electronic controller disposed within the vehicle;

wirelessly communicatively coupling the electronic controller to the electronic pushbuttons;

manually actuating the pushbuttons according to a code corresponding to a desired functionality of at least one of the pushbuttons;

wirelessly transmitting signals from the pushbuttons to the controller, the signals being dependent upon the manual actuation of the pushbuttons; and

programming a function of at least one of the pushbuttons based on the transmitted signals.

15. The method of claim 14 wherein each of the pushbuttons includes a respective microcontroller configured to function as a wireless gateway, the method comprising the further step of using the microcontrollers to translate protocol between wired and wireless domains.

16. The method of claim 15 wherein the microcontrollers are used to translate one of wireless protocol-to-Controller Area Network and wireless protocol-to-Local Interconnect Network.

17. The method of claim 14 wherein the electronic controller includes a microcontroller configured to function as a wireless gateway, the method comprising the further step of using the microcontroller to translate protocol between wired and wireless domains.

18. The method of claim 14, comprising the further steps of:

connecting a display to the controller; and

using the display to provide feedback to a user during the step of manually actuating the pushbuttons.

19. The method of claim 18, comprising the further step of using the display to display mappings between the pushbuttons and the programmed functions of the pushbuttons.

20. The method of claim 18, wherein the connecting step comprises connecting a Heads Up Display to the controller, the method comprising the further step of providing feedback to a user during normal operation of the pushbuttons.
