Abstract

Claims (45)

1. A vehicle driver control input device comprising:

a non-rotatable wheel having at least one track;

first and second hand grips movably engaged with said at least one track so that the first and second hand grips are movable along said at least one track to facilitate sending steering signals to a steer-by-wire system of a vehicle; and

at least one of said first and second hand grips having a demand input mechanism to facilitate sending other signals to other systems of the vehicle.

2. The vehicle driver control input device of claim 1 , wherein said demand input mechanism is one of an accelerator demand input mechanism to facilitate sending acceleration signals to an energy conversion system of the vehicle and a braking demand input mechanism to facilitate sending braking signals to a brake-by-wire system of the vehicle; and

at least one of said first and second hand grips having the other of said accelerator demand input mechanism and said braking demand input mechanism.

3. The vehicle driver control input device of claim 2 , wherein said accelerator demand input mechanism comprises an accelerator button positioned on a front surface of said one of said first and second hand grips.

4. The vehicle driver control input device of claim 2 , wherein said braking demand input mechanism comprises a braking button positioned on a front surface of said one of said first and second hand grips.

5. The vehicle driver control input device of claim 2 , wherein said braking demand input mechanism comprises a braking button positioned on a rear surface of said one of said first and second hand grips.

6. The vehicle driver control input device of claim 2 , wherein said accelerator demand input mechanism and braking demand input mechanism are positioned inside the wheel to facilitate operation by thumb.

7. The vehicle driver control input device of claim 1 , wherein said non-rotatable wheel is mounted on a post.

8. The vehicle driver control input device of claim 1 , wherein said first and second hand grips are sufficiently linked together such that they maintain a specified distance apart as they are moved for steering.

9. The vehicle driver control input device of claim 1 , wherein said wheel is circular.

10. A vehicle driver control input device comprising:

a support post;

a steering wheel rotatably mounted with respect to the support post and operatively connected to a steer-by-wire system of the vehicle to facilitate sending steering signals to the steer-by-wire system when the steering wheel is rotated;

an accelerator demand input mechanism operatively connected to the steering wheel and operatively connected to a by-wire energy conversion system of the vehicle to facilitate sending acceleration signals to the energy conversion system; and

a braking demand input mechanism operatively connected to the steering wheel and to a brake-by-wire system of the vehicle to facilitate sending braking signals to the brake-by-wire system.

11. The vehicle driver control input device of claim 10 , wherein said steering wheel is circular.

12. The vehicle driver control input device of claim 10 , wherein said steering wheel is U-shaped.

13. The vehicle driver control input device of claim 10 , further comprising:

first and second hand grips positioned on the steering wheel, and each having one of said accelerator demand input mechanism and braking demand input mechanism positioned thereon.

14. The vehicle driver control input device of claim 13 , wherein said accelerator demand input mechanism comprises an accelerator button positioned on a front surface of said respective one of said first and second hand grips.

15. The vehicle driver control input device of claim 13 , wherein said braking demand input mechanism comprises a braking button positioned on a front surface of said respective one of said first and second hand grips.

16. The vehicle driver control input device of claim 10 , wherein said braking demand input mechanism is positioned behind the steering wheel.

17. The vehicle driver control input device of claim 10 , wherein said accelerator demand input mechanism and braking demand input mechanism are positioned inside the wheel to facilitate operation by thumb.

18. The vehicle driver control input device of claim 10 , wherein said steering wheel has a diameter of approximately 10 inches.

19. A vehicle driver control input device comprising:

a non-rotatable wheel having at least one track and mounted on a post;

first and second hand grips movably engaged with said at least one track so that the first and second hand grips are movable along said at least one track to facilitate sending steering signals to a steer-by-wire system of a vehicle;

accelerator demand input buttons positioned on said first and second hand grips to facilitate sending acceleration signals to an energy conversion system of the vehicle;

braking demand input buttons positioned on said first and second hand grips to facilitate sending braking signals to a brake-by-wire system of the vehicle;

wherein said accelerator demand input buttons are positioned inside the wheel to facilitate operation by thumb; and

wherein said first and second hand grips are sufficiently linked together such that they maintain a specified distance apart as they are moved for steering.

20. A vehicle comprising:

a chassis;

at least three wheels operable with respect to the chassis;

a steering system mounted with respect to the chassis and responsive to non-mechanical control signals;

a braking system mounted with respect to the chassis and responsive to non-mechanical control signals;

an energy conversion system mounted with respect to the chassis and responsive to non-mechanical control signals;

a connection port mounted with respect to the chassis and operably connected to the steering, braking and energy conversion systems;

a non-rotatable wheel having at least one track;

first and second hand grips movably engaged with said at least one track so that the first and second hand grips are movable along said at least one track to facilitate sending steering signals to the steering system via the connection port;

at least one of said first and second hand grips having an accelerator demand input mechanism to facilitate sending acceleration signals to said energy conversion system via the connection port; and

at least one of said first and second hand grips having a braking demand input mechanism to facilitate sending braking signals to said braking system via the connection port.
