Abstract

Particular embodiments may provide a control system for a vehicle, which may include and memory coupled to the processors. The memory may include instructions executable by the processor. The processors may be operable when executing the instructions to receive signals from a mobile device which may be associated with a user and may also be wirelessly connected to the vehicle. The signals may be received by sensors of the vehicle. The processors may be further operable when executing instructions to identify a lighting mode for illuminating an area associated with a device location. The processors may be further operable when executing instructions to determine illumination fields and lighting properties based on the lighting mode and the device location. The processors may be further operable when executing instructions to control operation of lights of the vehicle in accordance with the illumination fields and the lighting properties.

First claim

The invention claimed is:

1. A control system for a vehicle, the control system comprising one or more processors and a memory coupled to the processors comprising instructions executable by the processor, the processors being operable when executing the instructions to:
receive, by one or more sensors of the vehicle, signals from a mobile device associated with a user and wirelessly connected to the vehicle;
identify a lighting mode for illuminating an area associated with a device location;
determine, based on the lighting mode and the device location, illumination fields and lighting properties; and
control operation of one or more lights of the vehicle in accordance with the illumination fields and the lighting properties.

2. The system of claim 1 , wherein the lighting mode comprises:
an environment mode;
a beam pattern mode, wherein the beam pattern mode comprises a spotlight mode, a work mode, or a directional mode; or
a manual mode.

3. The system of claim 2 , wherein the processors being operable when executing instructions to determine illumination fields and lighting properties is further based on the environment mode and are further operable when executing instructions to:
capture, by an image sensor of the vehicle, an image of an area proximate to the vehicle;
identify, based on the image, an environment; and
determine, based on the environment, the illumination fields and lighting properties.

4. The system of claim 2 , wherein the processors being operable when executing instructions to determine illumination fields and lighting properties is further based on the beam pattern mode and are further operable when executing instructions to:
determine, based on the device location, a location of a person; and
determine, based on the location of the person being within an illumination field of the illumination fields, the illumination field as occupied.

5. The system of claim 4 , wherein the processors being operable when executing instructions to determine illumination fields and lighting properties is further based on the beam pattern mode and are further operable when executing instructions to:
determine, based on the beam pattern mode being in the spotlight mode, the occupied illumination field as the illumination field;
determine, based on the beam pattern mode being in the work mode, illumination fields adjacent to the occupied illumination field as the illumination field; or
determine, based on the beam pattern mode being in the directional mode, the occupied illumination field as the illumination field.

6. The system of claim 1 , wherein the processors are further operable when executing instructions to:
determine, based on time intervals between signals captured by the one or more sensors, a location of the mobile device.

7. The system of claim 1 , wherein the processors are further operable when executing instructions to:
receive, by a sensor of the vehicle, signals from the mobile device; and
determine, based on information in the signals, a location of the mobile device, wherein the information comprises geo-spatial positioning data.

8. The system of claim 1 , wherein the processors being operable when executing instructions to determine illumination fields and lighting properties is further based on a location of a person and are further operable when executing instructions to:
capture, by an image sensor of the vehicle, an image of an area proximate to the vehicle;

identify, based on the image, a person being within the image; and
determine, based on the image, the location of the person.

9. The system of claim 8 , wherein the processors being operable when executing instructions to determine illumination fields and lighting properties is further based on a direction the person is facing, wherein a brightness of the lighting properties decreases when the person is facing towards the vehicle.

10. The system of claim 2 , wherein the processors being operable when executing instructions to determine illumination fields and lighting properties is further based on the manual mode and are further operable when executing instructions to:
configure the manual mode;
receive user-input associated with the illumination fields and lighting properties.

11. The system of claim 1 , wherein the processors being operable when executing instructions to determine illumination fields and lighting properties is further based on user gestures captured by an image sensor of the vehicle.

12. The system of claim 1 , wherein the processors are further operable when executing instructions to:
determine a location of the vehicle;
identify, based on the location of the vehicle, a maximum allowed brightness associated with the lighting properties; and
limit, based on the maximum allowed brightness, a brightness associated with the lighting properties.

13. The system of claim 1 , wherein the processors are further operable when executing instructions to:
identify, based on a location of the vehicle, allowed color temperatures associated with the lighting properties; and
limit, based on the allowed color temperatures, a color temperature associated with the lighting properties.

14. The system of claim 1 , wherein the processors being operable when executing instructions to determine illumination fields and lighting properties are further operable when executing instructions to:
determine, based on a time of day, a color temperature associated with the lighting properties.

15. The system of claim 14 , wherein the processors being operable when executing instructions to determine the color temperature are further operable when executing instructions to:
decrease the color temperature when a time at a location of the vehicle transitions from daytime to nighttime; or
increase the color temperature when the time at the location of the vehicle transitions from nighttime to daytime.

16. The system of claim 15 , wherein the processors being operable when executing instructions to determine the color temperature are further based on ambient lighting conditions captured by a sensor of the vehicle.

17. The system of claim 1 , wherein the processors are further operable when executing instructions to:
receive, by the one or more sensors, signals from a second mobile device associated with a second user and wirelessly connected to the vehicle;
modify the lighting mode based on a second area associated with a second device location; and
determine, based on the lighting mode and the second device location, illumination fields and lighting properties.

18. The system of claim 1 , wherein the processors are further operable when executing instructions to:
display, by the one or more lights, an image, a video, or an interactive game.

19. A method for configuring an illumination associated with a vehicle, the method comprising:
