Abstract

A steering wheel is configured as a dual-state input device configured to operate in two distinct states based on a current driving mode. In a manual driving mode, the input device is configured to control a limited set of vehicle functions and in an autonomous mode the input device is configured to control an expanded set of vehicle functions. The steering wheel includes a wheel rim movably mounted on a steering column and a hub disposed within a center of the wheel rim on the steering column, the main body portion comprising an interactive touch screen disposed on the main body portion. The wheel rim is configured to disengage from the hub and move along the steering column to a retracted position.

Claims

1. A steering wheel, comprising:

a wheel rim movably mounted on a steering column;

a hub disposed within a center of the wheel rim on the steering column; and

an input device disposed on the hub,

wherein the wheel rim is configured to disengage from the hub and move along the steering column to a retracted position.

2. The steering wheel according to claim 1, wherein the steering wheel is configured to change from a first operating state to a second operating state based on a driving mode of a vehicle in which the steering wheel is incorporated.

3. The steering wheel according to claim 1, wherein the wheel rim is configured to move to the retracted position when a vehicle, in which the steering wheel is incorporated, enters an autonomous driving mode.

4. The steering wheel according to claim 3, wherein, during the autonomous driving mode, the wheel rim is configured to rotate in accordance with a driving motion of the vehicle while the wheel rim is in the retracted position.

5. The steering wheel according to claim 3, wherein, in the autonomous driving mode, the hub is configured to move forward, away from the wheel rim.

6. The steering wheel according to claim 3, wherein, in the autonomous driving mode, the hub is configured such that its position is maintained without rotating with the wheel rim.

7. The steering wheel according to claim 1, wherein the input device comprises an interactive touch screen disposed on each side of the hub.

8. The steering wheel according to claim 1, wherein the input device is configured to provide different input options based on a driving mode of the vehicle.

9. The steering wheel according to claim 8, wherein in a manual driving mode the input device is configured to control a limited set of vehicle functions.

10. The steering wheel according to claim 8, wherein in an autonomous mode the input device is configured to control an expanded set of vehicle functions.

11. The steering wheel according to claim 1, wherein the input device is mounted to the hub by a spring-loaded hinge.

12. A system, comprising;

an electronic control unit configured to control a driving mode of a vehicle; and

the steering wheel according to claim 1, the steering wheel being connected to the electronic control unit,

wherein the steering wheel is configured to change from a first operating state to a second operating state based on the driving mode of the vehicle.

13. A vehicle, comprising:

the steering wheel according to claim 1.

14. A steering wheel, comprising:

a dual-state input device configured to operate in two distinct states based on a current driving mode,

wherein in a manual driving mode the input device is configured to control a limited set of vehicle functions, and

wherein in an autonomous mode the input device is configured to control an expanded set of vehicle functions.

15. The steering wheel according to claim 14, further comprising:

a wheel rim; and

a hub disposed within the wheel rim,

wherein the dual-state input device is mounted to the hub.

16. The steering wheel according to claim 15, wherein in the autonomous mode, the wheel rim is configured to disengage from the hub and move along the steering column to a retracted position.

17. A steering wheel, comprising:

a retractable steering tube;

a wheel rim movably mounted on the steering tube;

a hub mounted within the wheel rim on a stationary tube, the stationary tube extending from the retractable steering tube;

an input disposed on the hub; and

an actuator configured to retract and extend the retractable steering tube,

wherein the wheel rim is configured to disengage from the hub and move to a retracted position in response to the steering wheel entering an autonomous driving mode.
