Abstract

A user-configurable steering column is made from steering column-mounted switches, each of which is coupled to a computer, which is also coupled to various different driver circuits, each of which is configured to control the operation of a corresponding vehicle accessory device, such as head lamps, a wiper motor or the vehicle'"'"'s cruise control. A tactile-sensitive display device located in either a head unit, smartphone inside the vehicle, or in a dedicated, dash board-mounted device, provides a menu of assignable switches and user-controllable devices, or it displays icons representing the switches and accessories. A driver assigns a switch to a particular accessory by selecting icons. The computer thereafter reads the switches'"'"' states and sends corresponding control signals to the drivers for the various devices that were mapped to the switches. Multiple different programmed configurations can be stored in a memory device and selected by a user using the tactile-sensitive display device.

Claims

1. A user-configurable steering column for a vehicle comprising:

first and second steering column-mounted switches, each switch being configured to output an electrical signal responsive to a user'"'"'s mechanical operation thereof;

a radio frequency transceiver, configured to wirelessly communicate with a smartphone and configured to receive steering column-mounted switch configuration information therefrom;

a computer coupled to the first and second steering column-mounted switches and to the radio frequency transceiver;

a user-operable input device coupled to the computer;

an output display device coupled to the computer;

a first power controller coupled to the computer and coupled to a corresponding first accessory device, the first power controller configured to selectively operate the first accessory device, responsive to a control signal received by the first power controller; and

a second power controller coupled to the computer and coupled to a corresponding second accessory device, the second power controller configured to selectively operate the second accessory device, responsive to a control signal received by the second power controller;

wherein the computer is configured to selectively associate an electrical switch to different ones of the first and second power controllers responsive to an input signal received by the computer from either the user-operable input device or from the radio frequency transceiver.

2. The user-configurable steering column of claim 1, wherein the output display device is configured to display icons representing switches, which can be associated by the computer with different power controllers, and configured to display icons representing accessory devices, which are controlled by corresponding power controllers, wherein the input device, output display device and computer are configured to enable a user of the user-configurable steering column to select an icon representing a switch, select an icon representing an accessory and thereafter selectively control operation of the selected accessory by operating the selected switch.

3. The user-configurable steering column of claim 1, wherein, after a first electrical switch is associated with a first power controller and corresponding accessory, the computer is additionally configured to selectively control the first power controller and the corresponding first accessory device responsive to a signal received by the computer from the first electrical switch.

4. The user-configurable steering column of claim 3, wherein, after the first electrical switch is associated with the first power controller, the computer is additionally configured to selectively control the second power controller and the second accessory device responsive to a signal received by the computer from the second electrical switch.

5. The user-configurable steering column of claim 1, wherein the input device is a touch-sensitive panel, configured to receive a tactile input and generate an output signal responsive to the tactile input.

6. The user-configurable steering column of claim 5, wherein the input device is a dashboard-mounted, touch-sensitive display panel.

7. The user-configurable steering column of claim 1, wherein the input device and the output device comprise a touch-sensitive display panel, which is configured to display images, and receive tactile input and generate an output signal responsive to, and representative of, a received tactile input.

8. The user-configurable steering column of claim 7, wherein the input device and the output device comprise a touch-sensitive display panel that comprises a vehicle head unit.

9. The user-configurable steering column of claim 7, wherein the input device and the output device comprise a touch-sensitive display panel that comprises a mobile smartphone, inside the vehicle.

10. The user-configurable steering column of claim 1, wherein the display device is a heads-up display device, configured to cause icons to be displayed on a vehicle'"'"'s windshield in a driver'"'"'s line of sight.

11. The user-configurable steering column of claim 10, wherein the computer and display device are configured to display a first icon representative of a first, user-controllable accessory, a second icon, representative of a second, user-controllable accessory, a third icon representative of a first switch that was associated with and which controls the first, user-controllable accessory and a fourth icon, representative of a second switch a user-controlled accessory represented by the first displayed icon.

12. The user-configurable steering column of claim 10, wherein the first displayed icon and the second displayed icon are displayed together.

13. A user-configurable steering column comprising:

a switch matrix having a plurality of inputs and a plurality of outputs, the switch matrix being configured to selectively connect each of the plurality of inputs to a different one of the plurality of outputs, responsive to a control signal input to the switch matrix;

a plurality of steering column-mounted switches, each switch coupled to a corresponding input of the switch matrix, each switch configured to output a signal responsive to a user'"'"'s operation of the switch;

a user-operable input device;

a radio frequency transceiver, configured to wirelessly communicate with a smartphone and configured to receive steering column-mounted switch configuration information therefrom;

a computer coupled to the user-operable input device, the switch matrix and to the radio frequency transceiver;

and

a plurality of controllers, each coupled to a corresponding accessory device and configured to selectively provide electric energy to the corresponding accessory device responsive to a control signal received by a power controller from the switch matrix;

wherein the computer is configured to selectively associate a steering column-mounted switch to different power controllers responsive to an input signal received by the computer from either the user-operable input device or from the radio frequency transceiver.

14. The user-configurable steering column of claim 13, further comprising an output device coupled to the computer, the output device being configured to display icons representing the switches and icons representing accessory devices.

15. A method of selectively controlling electrically operable accessories by different switches, the method comprising the steps of:

displaying on a display device, icons representing vehicle accessory devices;

displaying on a display device, icons representing vehicle switches that can control vehicle accessory devices;

wirelessly receiving from a smartphone, a selection of a first switch to associate with a first accessory;

selecting an accessory to be associated with the first selected switch by wirelessly receiving a second input from the smartphone; and

coupling the selected first switch to the selected accessory, whereby the selected accessory is controlled by the selected switch.

16. The method of claim 15, wherein the step of coupling the selected first switch to the selected accessory comprises the steps of:

receiving a first electrical signal from the selected first switch at a computer;

outputting a second electrical signal from the computer and coupling the second electrical signal to the selected accessory.

17. The method of claim 15, wherein the steps of displaying icons representing accessory device and the step of displaying icons representing switches comprises displaying both icons on the same display device on the smartphone.

18. The method of claim 15, wherein the step of selecting a first switch comprises providing a first tactile input to a tactile-sensitive display device on the smartphone.
