Abstract

A vehicle interior system including a first seat assembly, disposed within a vehicle cabin, a first sensor, a second sensor, and a controller is provided. The first and second sensors may each be disposed within the vehicle cabin. The first sensor may be configured to obtain first signals indicative of a positioning of an obstacle within a predetermined coordinate system. The second sensor may be configured to obtain second signals indicative of a positioning of the first seat assembly within the predetermined coordinate system. The controller may be configured to receive the signals from the first sensor and to map a portion of the obstacle based on the first signals and relative to a portion of the first seat assembly within the predetermined coordinate system.

First claim

What is claimed is:

1. A vehicle interior system comprising:
a first seat assembly disposed within a vehicle cabin and including a motor configured to move at least a portion of the first seat assembly, wherein the motor is configured to output first signals indicative of a position of the portion of the first seat assembly within a predetermined coordinate system;
a sensor disposed within the vehicle cabin and configured to output second signals indicative of a positioning of an obstacle within the predetermined coordinate system; and
a controller configured to:
receive the second signals from the sensor and assign first coordinates to the obstacle to map the position of the obstacle within the predetermined coordinate system based on the second signals,
receive the first signals from the motor and assign second coordinates to the portion of the first seat assembly to map the positioning of the portion of the first seat assembly within the predetermined coordinate system based on the first signals,

responsive to actuation of the motor, iteratively update the second coordinates of the portion to track movement of the portion, and
stop the actuation of the motor responsive to a hinderance condition being detected, wherein the detection of the hinderance condition is based on a distance between the first and second coordinates and a speed of the movement of the portion of the first seat assembly.

2. The vehicle interior system of claim 1 , wherein the motor is a length adjustment motor configured to provide the first signals.

3. The vehicle interior system of claim 2 , wherein the first seat assembly further includes a recliner motor configured to move the first seat assembly, wherein the recliner motor is configured to output third signals to the controller indicative of a position of the portion of the first seat assembly within the predetermined coordinate system.

4. The vehicle interior system of claim 3 , wherein the first seat assembly further includes a height adjustment motor configured to output fourth signals to the controller indicative of the portion of the first seat assembly to determine the positioning of the portion of the first seat assembly within the predetermined coordinate system based on the first signals, the third signals, and the fourth signals.

5. The vehicle interior system of claim 4 , wherein the controller is further configured to record in memory the positioning of the portion of the first seat assembly.

6. The vehicle interior system of claim 1 , further comprising:
a second seat assembly including an adjustable headrest assembly having a headrest and a headrest motor, the headrest motor being configured to rotate in a first rotational direction to translate the headrest in a first direction and a second rotational direction to translate the headrest in a second direction, wherein the controller is configured to rotate the headrest motor in the second rotational direction to translate the headrest in the second direction from a first position to a second position, in response to meeting the hindrance condition.

7. The vehicle interior system of claim 6 , wherein the controller is further configured to record in memory the positioning of the adjustable headrest assembly in the first position before rotating the headrest motor in the second direction.

8. The vehicle interior system of claim 7 , wherein the controller is further configured to rotate the headrest motor in the first rotational direction to return the headrest to the first position.

9. The vehicle interior system of claim 1 , wherein the sensor is a RADAR sensor.
