Abstract

A steering assembly includes a steering wheel, a steering gear, and a sensor assembly. The steering wheel is connected to a steering column. The steering gear is selectively coupled to the steering wheel. The sensor assembly is disposed proximate the steering column. The steering wheel is decoupled from the steering gear and sensor assembly detects a condition of the driver and a position of the driver in response to a request to activate an autonomous driving assisted steering system.

Claims

1. A steering assembly, comprising:

a steering wheel connected to a steering column;

a steering gear selectively coupled to the steering wheel; and

a sensor assembly disposed proximate the steering column, the steering wheel is decoupled from the steering gear and the sensor assembly detects a condition of a driver and a position of the driver in response to a request to activate an autonomous driving assisted steering system.

2. The steering assembly of claim 1, wherein in response to the request to activate an autonomous driving assisted steering system the steering wheel switches from a rotatable condition to a non-rotatable condition.

3. The steering assembly of claim 1, wherein in response to the steering wheel being operatively decoupled from the steering gear, the steering wheel and the steering column moves from an extended position towards a retracted position.

4. The steering assembly of claim 1, further comprising an alert system in communication with the sensor assembly, the alert system outputs a warning in response to a signal provided by the sensor assembly indicative of at least one of a non-responsive driver and an unprepared driver.

5. The steering assembly of claim 1, wherein the sensor assembly includes at least one of a biometric sensor, an optical sensor, an ultrasonic sensor, a thermal sensor, an optical camera, a capacitive sensor, an inductive sensor, a SONAR device, an infrared detector, a LIDAR device, and a Radar device.

6. A steering assembly, comprising:

a steering wheel connected to a steering column provided with an autonomous vehicle, the steering wheel selectively coupled to a steering gear and movable between an extended position and a retracted position; and

a sensor assembly disposed proximate the steering column, the sensor assembly including a first sensor that provides a first signal indicative of a condition of a driver.

7. The steering assembly of claim 6, wherein in response to a request to activate an autonomous driving assisted steering system, the steering wheel is operatively decoupled from the steering gear.

8. The steering assembly of claim 6, wherein a driver condition warning is provided when the first signal indicates a non-responsive driver while an autonomous driving assisted steering system is active.

9. The steering assembly of claim 6, wherein the sensor assembly further includes a second sensor that provides a second signal indicative of a position of the driver.

10. The steering assembly of claim 9, wherein a driver position warning is provided when the second signal indicates a position of a driver not within a driver seat.

11. The steering assembly of claim 6, wherein the sensor assembly further includes a third sensor that provides a third signal indicative of an obstacle proximate a path of travel of the steering wheel.

12. The steering assembly of claim 11, wherein an obstacle warning is provided when the third signal indicates an obstacle proximate the path of travel of the steering wheel, in response to a second request to deactivate an autonomous driving assisted steering system.

13. A method of monitoring a space within an autonomous vehicle, comprising:

activating an autonomous driving assisted steering system;

detecting a condition of a driver of a vehicle with a sensor assembly while the autonomous driving assisted steering system is active, the sensor assembly providing a first signal indicative of the condition of the driver; and

providing a first warning to the driver when the first signal indicates a non-responsive driver.

14. The method of claim 13, further comprising steering the vehicle to a predetermined location in response to the first signal indicating the non-responsive driver.

15. The method of claim 13, further comprising detecting a position of the driver with the sensor assembly.

16. The method of claim 15, wherein the sensor assembly provides a second signal indicative of the position of the driver.

17. The method of claim 16, further comprising providing a second warning to the driver when the second signal indicates the position of the driver not within a driver'"'"'s seat.

18. The method of claim 13, further comprising detecting an obstacle proximate a path of travel of a steering wheel with the sensor assembly in response to a request to deactivate the autonomous driving assisted steering system.

19. The method of claim 18, wherein the sensor assembly provides a third signal indicative of the obstacle proximate the path of travel of the steering wheel.

20. The method of claim 19, further comprising providing a third warning to the driver when the third signal indicates the obstacle proximate the path of travel of the steering wheel.
