Abstract

A driver control input device includes a support post and a steering ring rotatably supported with respect to the support post. A steering transducer is operatively connected between the steering ring and support post to convert mechanical rotation of the steering ring into non-mechanical steering control signals to be sent to a steer-by-wire system. A braking ring and acceleration ring may also be provided for generating non-mechanical braking and acceleration control signals.

Claims

1. A driver control input device comprising:

a support post;

a steering ring rotatably supported with respect to the support post; and

a steering transducer operatively connected between the steering ring and the support post to convert mechanical rotation of the steering ring into non-mechanical steering control signals to be sent to a steer-by-wire system.

2. The driver control input device of claim 1, further comprising a hub fixed to the post, and wherein said steering ring is rotatably supported with respect to the hub, said hub including an information display.

3. The driver control input device of claim 1, further comprising a hub fixed to said steering ring for rotation therewith.

4. The driver control input device of claim 1, further comprising a braking ring operatively connected adjacent the steering ring and engaged with a braking transducer to convert mechanical motion of the braking ring into non-mechanical braking control signals to be sent to a brake-by-wire system.

5. The driver control input device of claim 1, further comprising an acceleration ring operatively connected adjacent the steering ring and engaged with an acceleration transducer to convert mechanical motion of the acceleration ring into non-mechanical acceleration control signals to be sent to an energy conversion system.

6. The driver control input device of claim 1, further comprising an acceleration button connected to said steering ring for providing non-mechanical acceleration signals to an energy conversion system.

7. The driver control input device of claim 1, further comprising a braking ring operatively connected adjacent a back side of the steering ring and an acceleration ring operatively connected adjacent a front side of the steering ring, said braking ring and acceleration ring being operable to provide non-mechanical braking signals and non-mechanical acceleration signals to a brake-by-wire system and an energy conversion system, respectively.

8. The driver control input device of claim 1, wherein said steering ring is substantially hollow and is positioned on a stationary wheel, and rotatable with respect to the stationary wheel via bearings on the stationary wheel abutting an inside surface of the hollow steering ring.

9. The driver control input device of claim 1, wherein said post rotatably supports the steering ring by engaging only a peripheral edge of the steering ring to thereby fully support the steering ring while enabling rotation of the steering ring via bearings connected to the post.

10. A driver control input device comprising:

a support post;

a steering ring rotatably supported with respect to the support post and engaged with a steering transducer to convert mechanical rotation of the steering ring into non-mechanical steering control signals to be sent to a steer-by-wire system;

an acceleration ring operatively connected adjacent the steering ring and engaged with an acceleration transducer to convert mechanical motion of the steering ring into non-mechanical acceleration control signals to be sent to an energy conversion system.

11. The driver control input device of claim 10, wherein said braking ring and acceleration ring are configured for axial movement with respect to the rotatable steering ring.

12. The driver control input device of claim 10, further comprising a hub fixed to the post, and wherein said steering ring is rotatably supported with respect to the hub, said hub including an information display.

13. The driver control input device of claim 10, further comprising a hub fixed to said steering ring for rotation therewith.

14. The driver control input device of claim 10, further comprising an acceleration button connected to said steering ring for providing non-mechanical acceleration signals to said energy conversion system.

15. The driver control input device of claim 10, wherein said braking ring is operatively connected adjacent a back side of the steering ring, and said acceleration ring is operatively connected adjacent a front side of the steering ring.

16. The driver control input device of claim 10, wherein said steering ring is substantially hollow and is positioned on a stationary wheel, and rotatable with respect to the stationary wheel via bearings on the stationary wheel abutting an inside surface of the hollow steering ring.

17. The driver control input device of claim 10, wherein said post rotatably supports the steering ring by engaging only a peripheral edge of the steering ring to thereby fully support the steering ring while enabling rotation of the steering ring via bearings connected to the post.

18. A vehicle comprising:

a chassis;

at least three wheels operatively connected with respect to the chassis;

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

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