Abstract

A manually retractable steering column assembly includes a retractable portion translatable upon exertion of a manual force applied by a driver, the retractable portion restricted to a first translation range during a standard driving mode and translatable within a second translation range during an autonomous driving mode, the second translation range greater than the first translation range.

Claims

1. A manually retractable steering column assembly comprising:

a retractable portion translatable upon exertion of a manual force applied by a driver;

a stationary portion defining a slot path at least partially defined by a first end wall and a second end wall;

a member operatively coupled to, and projecting outwardly from, the retractable portion; and

a gate operatively coupled to the stationary portion proximate the second end wall, the gate having an edge protruding into the slot path, the member extending through, and moveable within, the slot path during translation of the retractable portion, the first end wall and the edge of the gate defining a first translation range of the retractable portion available during a standard driving mode, the gate moveable to dispose the edge of the gate out of the slot path to allow a second translation range of the retractable portion available during an autonomous driving mode.

2. The assembly of claim 1, wherein the gate includes a contoured recess for receiving the member in the autonomous driving mode, the member removable from the contoured recess to translate the retractable portion to the first translation range upon exertion of a force on the retractable portion toward the first end wall of the slot path.

3. The assembly of claim 1, further comprising an actuator operatively coupled to the gate to impart movement of the gate.

4. The assembly of claim 3, wherein the actuator comprises an electric motor.

5. The assembly of claim 3, wherein the actuator comprises a solenoid.

6. The assembly of claim 3, wherein the actuator is in operative communication with an advanced driver assist system (ADAS) to determine if a vehicle is in the autonomous driving mode or the standard driving mode.

7. The assembly of claim 6, wherein the ADAS comprises a sensor to determine if the retractable portion is in a stowed condition.

8. The assembly of claim 3, wherein the actuator translates the gate.

9. The assembly of claim 3, wherein the actuator pivots the gate.

10. The assembly of claim 1, wherein the member comprises a cylindrical pin.

11. A manually retractable steering column assembly comprising a retractable portion translatable upon exertion of a manual force applied by a driver, and a stationary portion attached thereto, the retractable portion restricted to a first translation range during a standard driving mode and translatable within a second translation range during an autonomous driving mode, a gate operatively coupled to the stationary portion, the gate restricting translation of the retractable portion to the first translation range during the standard driving mode, the gate moveable to allow the second translation range during the autonomous driving mode, the second translation range greater than the first translation range.

12. A manually retractable steering column assembly for an autonomous vehicle comprising:

a retractable portion translatable upon exertion of a manual force applied by a driver;

a stationary portion defining a slot path at least partially defined by a first end wall and a second end wall;

a member operatively coupled to, and projecting outwardly from, the retractable portion; and

a gate operatively coupled to the stationary portion proximate the second end wall, the gate restricting translation of the retractable portion to a first translation range during a standard driving mode, the gate moveable to allow a second translation range during an autonomous driving mode, the gate having a contoured recess for receiving the member in the autonomous driving mode, the member removable from the contoured recess to translate the retractable portion to the first translation range upon exertion of a force on the retractable portion toward the first end wall of the slot path.

13. The assembly of claim 12, further comprising an actuator operatively coupled to the gate to impart movement of the gate.

14. The assembly of claim 13, wherein the actuator comprises an electric motor.

15. The assembly of claim 13, wherein the actuator comprises a solenoid.

16. The assembly of claim 13, wherein the actuator is in operative communication with an advanced driver assist system (ADAS) to determine if a vehicle is in the autonomous driving mode or the standard driving mode.

17. The assembly of claim 16, wherein the ADAS comprises a sensor to determine if the retractable portion is in a stowed condition.

18. The assembly of claim 13, wherein the actuator translates the gate.

19. The assembly of claim 13, wherein the actuator pivots the gate.

20. The assembly of claim 12, wherein the member comprises a cylindrical pin.

21. A manually retractable steering column assembly comprising a retractable portion translatable upon exertion of a manual force applied by a driver, the retractable portion restricted to a first translation range during a standard driving mode and translatable within a second translation range during an autonomous driving mode, the second translation range having an autonomous range outside the first translation range, the retractable portion configured to be manually extensible from the autonomous range to the first translation range.
