Abstract

According to one aspect, personalized vehicle ambient lighting on a vehicle is provided. Presence information associated with a user is detected. Image color information is captured from an image is taken by a camera such that the user is within the image. Image color information associated with the user is extracted from the image. Red, green, blue (RGB) color values indicative of a color associated with the user are created. A light emitting diode (LED) activation scheme based on the RGB color values associated with the user is generated. Portions of a plurality of RGB LEDs are activated based on the LED activation scheme.

First claim

What is claimed is:

1. A system for personalized vehicle ambient lighting on a vehicle, comprising:
a vehicle entry sensor detecting presence information associated with a user;
a camera comprising an image sensor capturing image color information from an image taken by the camera;
a controller having a processor operably connected to the camera and controlling the camera to take the image when the user is in view of the camera;
an image processor extracting image color information associated with the user from the image and creating red, green, blue (RGB) color values indicative of a color associated with the user, wherein the processor for the controller generates a light emitting diode (LED) activation scheme based on the RGB color values associated with the user;
a first plurality of red, green, blue (RGB) LEDs; and
a first LED driver connected to the controller and the first plurality of RGB LEDs and activating portions of the first plurality of RGB LEDs based on the LED activation scheme to produce personalized vehicle ambient lighting having a color matching the color associated with the user.

2. The system of claim 1 , comprising:
a second plurality of RGB LEDs; and
a second LED driver connected to the controller and the second plurality of RGB LEDs and activating portions of the second plurality of RGB LEDs based on the LED activation scheme.

3. The system of claim 2 , wherein the second LED driver activates portions of the second plurality of RGB LEDs based on the LED activation scheme to produce personalized vehicle ambient lighting having a color different than the color of the first plurality of RGB LEDs.

4. The system of claim 1 , wherein the first plurality of RGB LEDs is associated with a puddle light system, an internal ambient lighting system, or an external ambient lighting system.

5. The system of claim 1 , wherein the vehicle entry sensor detects the presence information associated with the user based on a proximity of a key fob from the vehicle entry sensor.

6. The system of claim 5 , wherein the processor for the controller generates the LED activation scheme based on a profile associated with the key fob when image color information associated with the user is unavailable.

7. The system of claim 1 , wherein the vehicle entry sensor is a touch sensor which detects the presence information associated with the user based on contact between the user and a door or door handle of the vehicle.

8. The system of claim 1 , wherein the controller controls the camera to pan and motion track the user or focus lock on the user while the user is moving.

9. The system of claim 1 , wherein the image processor extracts image color information associated with an article of clothing of the user and creates the RGB color values indicative of a color associated with the article of clothing, and wherein the processor for the controller generates the LED activation scheme based on the RGB color values associated with the article of clothing.

10. The system of claim 1 , wherein the processor for the controller generates the LED activation scheme based on a time of day, a weather report, a predetermined color palette, or randomly when image color information associated with the user is unavailable.

11. The system of claim 10 , comprising a telematics unit receiving the time of day or the weather report.

12. The system of claim 10 , wherein the controller comprises a memory storing the predetermined color palette.

13. The system of claim 1 , wherein the processor for the controller generates the LED activation scheme on a continually updated basis based on a speed at which the user is walking, and wherein the LED activation scheme includes an adjustment to a brightness, an intensity, or a duration of activation based on the speed of the user.

14. The system of claim 1 , wherein the LED activation scheme includes an adjustment to a brightness, an intensity, or a duration of activation based on a proximity of the user to the vehicle.

15. A method for personalized vehicle ambient lighting on a vehicle, comprising:
detecting presence information associated with a user;
capturing image color information from an image taken by a camera such that the user is within the image;
extracting image color information associated with the user from the image;
creating red, green, blue (RGB) color values indicative of a color associated with the user;
generating a light emitting diode (LED) activation scheme based on the RGB color values associated with the user; and
activating portions of a plurality of RGB LEDs based on the LED activation scheme.

16. The method of claim 15 , wherein the plurality of RGB LEDs is associated with a puddle light system, an internal ambient lighting system, or an external ambient lighting system.

17. The method of claim 15 , comprising:
identifying an article of clothing of the user;
extracting image color information associated with the article of clothing of the user from the image;
creating RGB color values indicative of a color associated with the article of clothing; and
generating the LED activation scheme based on the RGB color values associated with the article of clothing.

18. The method of claim 17 , comprising:
extracting predominant image color information and secondary image color information associated with the user from the image;
creating RGB color values indicative of the predominant color and the secondary color; and
generating the LED activation scheme based on the RGB color values associated with predominant color or the secondary color.

19. The method of claim 18 , comprising:
generating a second LED activation scheme based on the secondary color; and
activating portions of a second plurality of RGB LEDs based on the second LED activation scheme.

20. A method for personalized vehicle ambient lighting on a vehicle, comprising:
detecting presence information associated with a user;
capturing image color information from an image taken by the camera such that the user is within the image;
extracting a first and second image color information associated with the user from the image;
creating first and second red, green, blue (RGB) color values indicative of a first and second color associated with the user based on the extracted first and second image color information;
generating a first and second light emitting diode (LED) activation scheme based on the first and second RGB color values associated with the user; and
activating portions of a first and second plurality of RGB LEDs based on the first and second LED activation schemes, respectively.
