Abstract

A steering wheel assembly for an automobile having integrated brake and throttle controls, said assembly comprising a steering wheel having a rim and a first twist grip having longitudinal axis and a second twist grip having a longitudinal axis, said first twist grip and said second twist grip being integral with said rim of steering wheel, wherein rotation of said first twist grip around its longitudinal axis operates said brake, and rotation of said second twist grip around its longitudinal axis operate said throttle.

Claims

1. A steering wheel assembly for an automobile having integrated brake and throttle controls, said assembly comprising:

a steering wheel having a rim; and

a first twist grip having a longitudinal axis and a second twist grip having a longitudinal axis, said first twist grip and said second twist grip being integral with said rim of said steering wheel, wherein rotation of said first twist grip around its longitudinal axis operates said brake, and rotation of said second twist grip around its longitudinal axis operates said throttle.

2. The steering wheel assembly according to claim 1 wherein said first twist grip is electrically coupled to said brake control so that rotating said first twist grip around its longitudinal axis causes a first control signal to be transmitted to a first controller, said first controller being in communication with a first actuator, and said first actuator controlling braking of said automobile.

3. The steering wheel assembly according to claim 2 wherein said first twist grip is a first rheostat so that rotation of said first twist grip around its longitudinal axis varies said first control signal in accordance with the rotation of said first twist grip.

4. The steering wheel assembly according to claim 3 wherein said first controller'"'"'s output varies according to said first control signal, and said first actuator is responsive to said first controller'"'"'s variable output.

5. The steering wheel assembly according to claim 2 wherein said first twist grip comprises a first displaceable member having indexing indicia, a first sensor for detecting a physical position of said indexing indicia, and a first signal generator in communication with said first sensor for generating said first control signal in accordance with said physical position of said indexing indicia, so that the rotation of said first twist grip around its longitudinal axis causes said first control signal generated by said first signal generator to vary according to said physical position of said indexing indicia.

6. The steering wheel assembly according to claim 5 wherein said first controller'"'"'s output varies according to said first control signal, and said first actuator is responsive to said first controller'"'"'s variable output.

7. The steering wheel system according to claim 2 wherein said second twist grip is electrically coupled to said throttle control so that rotation of said second twist grip around its longitudinal axis causes a second control signal to be transmitted to a second controller, said second controller being in communication with a second actuator, and said second actuator controlling said throttle of said automobile.

8. The steering wheel assembly according to claim 7 wherein said second twist grip is a second rheostat so that rotation of said second twist grip around its longitudinal axis varies said second control signal in accordance with said rotation of said second twist grip.

9. The steering wheel assembly according to claim 8 wherein said second controller'"'"'s output varies according to said second control signal, and said second actuator is responsive to said second controller'"'"'s variable output.

10. The steering wheel assembly according to claim 7 wherein said second twist grip comprises a second displaceable member having indexing indicia, a second sensor for detecting a physical position of said indexing indicia, and a second signal generator in communication with said second sensor for generating said second control signal in accordance with said physical position of said indexing indicia, so that rotation of said second twist grip around its longitudinal axis causes said second control signal generated by said second signal generator to vary according to said physical position of said indexing indicia.

11. The steering wheel assembly according to claim 9 wherein said second controller'"'"'s output varies according to said second control signal, and said second actuator is responsive to said second controller'"'"'s variable output.

12. The steering wheel assembly according to claim 1 wherein mounted on said steering wheel assembly is at least one button in communication with said automobile'"'"'s transmission gearbox such that by depressing said at least one button, said transmission gearbox changes gears.

13. The steering wheel assembly according to claim 1 wherein said first twist grip of said automobile and said second twist grip of said automobile can be selectively disabled.

15. The steering wheel assembly according to claim 14 wherein said first twist grip is a first rheostat so that rotation of said first twist grip around its longitudinal axis varies said first control signal in accordance with the rotation of said first twist grip, said first controller'"'"'s output varies according to said first control signal, and said first actuator is responsive to said first controller'"'"'s variable output.

16. The steering wheel assembly according to claim 14 wherein said first twist grip comprises a first displaceable member having indexing indicia, a first sensor for detecting a physical position of said indexing indicia, and a first signal generator in communication with said first sensor for generating said first control signal in accordance with said physical position of said indexing indicia, so that the rotation of said first twist grip around its longitudinal axis causes said first control signal generated by said first signal generator to vary according to said physical position of said indexing indicia, said first controller'"'"'s output varies according to said first control signal, and said first actuator is responsive to said first controller'"'"'s variable output.

17. The steering wheel assembly according to claim 14 wherein said second twist grip is a second rheostat so that rotation of said second twist grip around its longitudinal axis varies said second control signal in accordance with said rotation of said second twist grip, said second controller'"'"'s output varies according to said second control signal, and said second actuator is responsive to said second controller'"'"'s variable output.

18. The steering wheel assembly according to claim 14 wherein said second twist grip comprises a second displaceable member having indexing indicia, a second sensor for detecting a physical position of said indexing indicia, and a second signal generator in communication with said second sensor for generating said second control signal in accordance with said physical position of said indexing indicia, so that rotation of said second twist grip around its longitudinal axis causes said second control signal generated by said second signal generator to vary according to said physical position of said indexing indicia, said second controller'"'"'s output varies according to said second control signal, and said second actuator is responsive to said second controller'"'"'s variable output.

19. The steering wheel assembly according to claim 14 wherein mounted on said steering wheel assembly is at least one button in communication with said automobile'"'"'s transmission gearbox such that by depressing said at least one button, said transmission gearbox changes gears.

20. The steering wheel assembly according to claim 14 wherein said first twist grip of said automobile and said second twist grip of said automobile can be disabled.
