Abstract

Example embodiments presented herein are directed toward a seat assembly, and corresponding method, for seat retraction in a vehicle during an autonomous driving mode. Seat refraction is provided by detecting a user initiated input for the retraction. Thereafter, a front seat is refracted such that an occupant of the front seat is out of reach of at least one driving control input device, for example, a steering wheel, pedals or a gear shift, during an autonomous driving mode. Such seat retraction prevents the occupant from providing inadvertent driving inputs to the driving control input devices during the autonomous driving mode.

Claims

1. A method for seat retraction in a vehicle during an autonomous driving mode, the method comprising:

detecting a user initiated command to perform seat retraction;

automatically retracting a front seat in a rearward direction in response to the user initiated command such that an occupant of the front seat is out of reach of at least one engaged driving control input device of the vehicle during an autonomous driving mode; and

automatically returning the front seat in a forward direction to an initial position when an end to the autonomous driving mode is expected or upon detection of a user initiated command.

2. The method of claim 1 wherein the detecting further comprises detecting the user initiated command in a form of a position or movement of the occupant.

3. The method of claim 1 wherein the retracting further comprises retracting the front seat a distance according to an occupant provided profile and/or sensor data.

4. The method of claim 1 wherein the retracting further comprises retracting the front seat at a varying speed profile.

5. The method of claim 1 further comprising maintaining the at least one driving control input device in a state in which the at least one driving control input device is configured to receive a driving input subsequent to the retracting of the front seat that overrides the autonomous driving mode of the vehicle.

6. The method of claim 1 wherein retracting the front seat in the rearward direction comprises sliding the front seat along at least one rail connected to a floor of the vehicle so that the front seat is out of reach of the at least one engaged driving control input device during the autonomous driving mode.

7. The method of claim 6 wherein the at least one engaged driving control input device comprises a foot pedal.

8. A seat assembly for retracting a front seat in a vehicle during an autonomous driving mode, the seat assembly comprising:

a control unit configured to detect a user initiated command to perform seat retraction; and

a front seat controllable by the control unit and configured to slide along at least one rail, the at least one rail being connectable to a floor surface of the vehicle, wherein the front seat is configured to automatically retract in a rearward direction along the at least one rail in response to the user initiated command such that an occupant of the front seat is out of reach of at least one driving control input device of the vehicle during an autonomous driving mode when the at least one driving control input device is engaged, and wherein the front seat is configured to automatically return in a forward direction to an initial position when an end to the autonomous driving mode is expected or upon detection of a user initiated command.

9. The seat assembly of claim 8 wherein the control unit is further configured to detect the user initiated command in a form of a position or movement of the occupant.

10. The seat assembly of claim 8 wherein the front seat is further configured to retract a distance according to an occupant provided profile and/or sensor data.

11. The seat assembly of claim 8 further comprising an actuator configured to control the retraction of the front seat at a varying speed profile.

12. The seat assembly of claim 8 wherein the front seat is further configured to move along the at least one rail in a forward direction to an initial position when an end to an autonomous driving mode is expected or upon detection of a user initiated command.

13. The seat assembly of claim 8 wherein the control unit is further configured to maintain the at least one driving control input device in a state in which the at least one driving control input device is configured to receive a driving input subsequent to the retraction of the front seat that overrides the autonomous driving mode of the vehicle.

14. A vehicle comprising the seat assembly of claim 8.

15. A non-transitory computer readable medium comprising stored program instructions for seat retraction in a vehicle during an autonomous driving mode, the program instructions for execution by one or more processors to carry out steps of:

detecting a user initiated command to perform seat retraction;

automatically retracting a front seat in a rearward direction in response to the user initiated command such that an occupant of the front seat is out of reach of a steering wheel and foot pedals of the vehicle during an autonomous driving mode when the steering wheel and foot pedals are engaged; and

automatically returning the front seat in a forward direction to an initial position when an end to an autonomous driving mode is expected or upon detection of a user initiated command.

16. The computer readable medium of claim 15 further comprising executable instructions for causing the one or more processors to carry out the detecting such that the detecting further comprises detecting the user initiated command in a form of a position or movement of the occupant.

17. The computer readable medium of claim 15 further comprising executable instructions for causing the one or more processors to carry out the retracting such that the retracting further comprises retracting the front seat a distance according to an occupant provided profile and/or sensor data.

18. The computer readable medium of claim 15 further comprising executable instructions for causing the one or more processors to carry out the retracting such that the retracting further comprises retracting the front seat at a varying speed profile.

19. The computer readable medium of claim 15 further comprising executable instructions for causing the one or more processors to carry out a step of maintaining the at least one driving control input device in a state in which the at least one driving control input device is configured to receive a driving input subsequent to the retracting of the front seat that overrides the autonomous driving mode of the vehicle.
