Abstract

Vehicle includes a vehicular frame and a steering wheel connected to the vehicular frame, the steering wheel includes an annular frame and one or more user-manipulatable input devices arranged thereon. Each input device includes electronic components which initiate a change in the operation of a component of the vehicle or a display system based on the user'"'"'s manipulation thereof. Types of input devices include a joy stick, trackball, directional pad or scroll wheel, as well as a universal stick actuator. A display system includes a display arranged to be visible to the driver, with the input device or devices being arranged to control the display system to alter the display upon being manipulated. The display system can be programmed to display menus on the display. Variation of the menus and selection of items on the menus may be implemented by the input device(s).

Claims

1. A vehicle, comprising:

a vehicular frame; and

a steering wheel connected to said vehicular frame,

said steering wheel including an annular frame and at least one user-manipulatable input device arranged on said annular frame, said at least one input device including electronic components which initiate a change in the operation of a component of the vehicle or a display system based on the user'"'"'s manipulation of said at least one input device.

2. The vehicle of claim 1, wherein said at least one input device is structured to receive power inductively, further comprising an inductive power system for providing power inductively to said at least one input device.

3. The vehicle of claim 1, further comprising:

an indication determining system for determining when an indication to the driver is desired based on the operation or use of the vehicle; and

haptic means arranged in connection with said steering wheel and said indication determining system for causing only a portion of said steering wheel to vibrate, generate an electrical shock or provide another haptic stimulus in response to the determination of the need for an indication to the driver.

4. The vehicle of claim 3, wherein said haptic means are arranged in connection with said at least one input device to vibrate, generate the electrical shock or provide the other haptic stimulus when the indication to the driver is the need to manipulate said at least one input device.

5. The vehicle of claim 3, wherein said indication determining system is arranged to determine when an incoming telephone call to the driver has been received, said haptic means being arranged to vibrate said at least one input device associated with connecting to the incoming call.

6. The vehicle of claim 1, wherein said at least one input device is a joy stick, trackball, directional pad or scroll wheel.

7. The vehicle of claim 1, further comprising a display system including a display arranged to be visible to the driver, said at least one input device being arranged to control said display system to alter said display upon being manipulated.

8. The vehicle of claim 7, wherein said display system is arranged to display menus on said display, said at least one input device comprising three input devices, a first one of said input devices being activated to cause highlighting on a menu selection to move up, a second one of said input devices being activated to cause highlighting on a menu selection to move down and a third one of said input devices being activated to cause the highlighted item to be chosen or selected.

9. The vehicle of claim 7, wherein said at least one input device is a switch arranged to cause the change in the operation of the component of the vehicle or said display system based on the user'"'"'s manipulation of said switch.

10. The vehicle of claim 1, wherein said steering wheel further comprises an airbag module including a folded airbag, said at least one input device comprising first and second input devices, said first input device being a touch pad arranged in front of said airbag and said second input device being arranged on a rim of said steering wheel.

11. The vehicle of claim 10, wherein said touch pad includes a cover and a capacitive sensor defined by spaced apart conductors underneath said cover, whereby touching of said cover by the user causes completion of a circuit allowing for detection of the position on said cover touched by said user.

12. The vehicle of claim 1, wherein said at least one input device is a touch pad including a cover positioned to be touched by the user, a serpentine tube arranged underneath said cover, and an ultrasonic transducer at each end of said tube, said transducer being arranged to direct waves through said tube whereby touching of said cover by the user causes collapse of said tube with the position of touch being determinable based on the reception of the waves by said transducers.

13. The vehicle of claim 1, wherein said at least one input device is a touch pad including a rigid plate and load or force sensors arranged at corners of and underneath said plate such that analysis of readings provided by said load or force sensors at said corners of said plate when said plate is touched by a user enable a determination of the position and force of the touching of the user to be determined.

14. The vehicle of claim 1, wherein said at least one input device includes a wireless or powerless switch.

15. The vehicle of claim 1, wherein said steering wheel further comprises a processor connected to said at least one input device and arranged to convert user manipulation of said at least one input device into a command for initiating a change in the operation of the component of the vehicle or the display.

16. The vehicle of claim 1, wherein said at least one input device is a universal stick actuator.

17. A vehicle including a dual-haptic control system, comprising:

a steering wheel;

a first haptic controller arranged on said steering wheel; and

a second haptic controller arranged apart from said steering wheel,

said first and second haptic controllers being arranged to convert touching by an occupant of the vehicle into a responsive action involving the vehicle or a component thereof or therein.

18. The vehicle of claim 17, wherein said first and second haptic controllers are touch pads.

19. The vehicle of claim 17, wherein said first haptic controller is positioned to be accessible by a driver of the vehicle and said second haptic controller is positioned to be accessible by a passenger of the vehicle.

20. The vehicle of claim 19, further comprising a display system including a first display arranged to be visible to the driver and a second display arranged to be visible to the passenger, said first and second haptic controllers being arranged to control said display system to alter said displays upon being touched.
