Abstract

Example embodiments presented herein are directed toward a steering wheel assembly, and corresponding method, for retracting a steering wheel in a vehicle. In the steering wheel retraction, a steering column is configured to first pivot upwards about a horizontal axis directed along the vehicle'"'"'s width via a pivoting member. Thereafter, the steering wheel column is configured to slide, via an actuating member, in a forward direction towards the instrument panel of the vehicle. Thus, before moving the steering column in a forward direction, the steering wheel is moved away from the driver'"'"'s legs by the pivoting action. This helps reduce the likelihood of the steering wheel hitting the driver'"'"'s legs during the retraction.

Claims

1. A steering wheel assembly for a vehicle, the steering wheel assembly comprising:

a steering wheel;

a steering column attachable to the steering wheel;

a pivoting member attachable to the steering column and a cross-beam structure of the vehicle, wherein the pivoting member is configured to pivot the steering column in an upward direction about a horizontal axis directed along a width of the vehicle; and

an actuating member configured to initiate a sliding of the steering column in a forward direction toward an instrument panel of the vehicle;

wherein the steering wheel is retractable from a normal driving position by first pivoting the steering column upward via the pivoting member and thereafter sliding the steering column forward via the actuating member.

2. The steering wheel assembly of claim 1 wherein the pivoting member is a rotational joint activatable by an electrical motor, a worm gear, or lever connected to a linear actuator

3. The steering wheel assembly of claim 1 wherein the steering column is configured to pivot a maximum of 90 degrees.

4. The steering wheel assembly of claim 1 wherein the actuating member is configured to initiate a sliding of the steering column within a range 10 to 100 centimeters.

5. The steering wheel assembly of claim 1 wherein the pivoting member and/or the actuating member are/is configured to halt the pivoting of and/or the sliding of the steering column, respectively, upon a detection of a resistance during the retraction of the steering wheel.

6. A vehicle comprising the steering wheel assembly of claim 1.

7. The vehicle of claim 6 wherein the steering wheel assembly is configured to retract the steering wheel once the vehicle detects a start of a non-driving period and/or a front driver seat of the vehicle is retracted toward the rear of the vehicle a predetermined amount.

8. The vehicle of claim 6 wherein the steering wheel assembly is configured to position the steering wheel in a driving position once the vehicle is expected to conclude the non-driving period and/or a front driver seat of the vehicle returns to a driving position.

9. A method for retracting a steering wheel of a steering wheel assembly in a vehicle, wherein the steering wheel assembly further comprises a steering column connected to the steering wheel, a pivoting member connecting the steering column to a cross-beam structure of the vehicle, and an actuating member, the method comprising:

receiving, by the steering wheel assembly, an indication for steering wheel retraction;

pivoting the steering column, via the pivoting member, in an upward direction about a horizontal axis directed along the vehicle'"'"'s width; and

thereafter, initiating a sliding of the steering column, via the actuating member, in a forward direction toward an instrument panel of the vehicle.

10. The method of claim 9 wherein the steering wheel assembly further comprises a control unit, and the receiving the indication comprises receiving the indication by the control unit.

11. The method of claim 10 wherein the receiving the indication further comprises detecting, by the control unit, a non-driving period has started and/or receiving a user initiated command.

12. The method of claim 9 wherein the receiving the indication further comprises detecting, by the steering wheel assembly, a non-driving period has started and/or receiving a user initiated command.

13. The method of claim 9 further comprising:

receiving, by the steering wheel assembly, an indication for returning the steering wheel to the driving position;

initiating a sliding of the steering column, via the actuating member, in an rearward direction, towards the driver; and

thereafter, pivoting the steering column, via the pivoting member, in a downward direction to restore the desired manual driving position.

14. The method of claim 13 wherein the receiving the indication further comprises detecting, by the steering wheel assembly, an end of a non-driving period and/or receiving a user initiated command.

16. A non-transitory computer readable medium comprising program instructions for retracting a steering wheel of a steering wheel assembly in a vehicle, wherein the steering wheel assembly further comprises a steering column connected to the steering wheel, a pivoting member connecting the steering column to a cross-beam structure of the vehicle, and an actuating member, wherein the program instructions are configured for execution by one or more processors of a computer system and comprise instructions for:

upon receipt of an indication for steering wheel retraction, pivoting the steering column, via the pivoting member, in an upward direction about a horizontal axis directed along a width of the vehicle; and

thereafter, initiating a sliding of the steering column, via the actuating member, in forward direction towards an instrument panel of the vehicle.

17. The computer readable medium of claim 16 wherein the indication for steering wheel retraction is a detection that a non-driving period has started and/or a user initiated command.

18. The computer readable medium of claim 16 further comprising instructions for:

upon receipt of an indication for returning the steering wheel in a driving position,

initiating a sliding of the steering column, via the actuating member, in an rearward direction, toward the driver; and

thereafter, pivoting the steering column, via the pivoting member, in a downward direction to restore a manual driving position.

19. The computer readable medium of claim 18 wherein the indication for returning the steering wheel is a detected end of a non-driving period and/or a user initiated command.
