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

1 . A control system, comprising:
one or more memories storing instructions; and one or more processors coupled to the one or more memories and configured to execute the instructions to cause the control system to:
determine, via one or more sensors, a location of a mobile device in wireless communication with a vehicle;
identify a lighting mode for illuminating an area associated with the location of the mobile device; and
control one or more lights of the vehicle based on the lighting mode.

2 . The control system of claim 1 , wherein the one or more processors are further configured to execute the instructions to cause the control system to:
determine, based on the lighting mode and the location of the mobile device, one or more illumination fields and one or more lighting properties, wherein controlling the one or more lights is further based on the one or more illumination fields and the one or more lighting properties.

3 . The control system of claim 2 , wherein the one or more processors are further configured to execute the instructions to cause the control system to:
capture, via an image sensor of the vehicle, an image of an area proximate to the vehicle; identify, based on the image, an environment of the vehicle; and determine, based on the environment of the vehicle, the one or more illumination fields and the one or more lighting properties.

4 . The control system of claim 2 , wherein the one or more processors are further configured to execute the instructions to cause the control system to:
determine, based on the location of the mobile device, a user location; and determine that the user location occupies a first illumination field included in the one or more illumination fields.

5 . The control system of claim 4 , wherein the one or more processors are further configured to execute the instructions to cause the control system to:
select, based on the lighting mode being a spotlight mode, the first illumination field as the area being illuminated; select, based on the lighting mode being a work mode, at least one illumination field adjacent to the first illumination field as the area being illuminated; or select, based on the lighting mode being a directional mode, the first illumination field as the area being illuminated.

6 . The control system of claim 1 , wherein the control system determines the location of the mobile device based on time intervals between signals received by the one or more sensors.

7 . The control system of claim 1 , wherein the location of the mobile device comprises geo-spatial positioning data.

8 . The system of claim 2 , wherein the one or more processors are further configured to execute the instructions to cause the control system 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 within the image; and determine, based on the image, a location of the person, wherein the control system determines the one or more illumination fields and the one or more lighting properties based on the location of the person.

9 . The control system of claim 8 , wherein the control system determines the one or more illumination fields and the one or more lighting properties based on a direction the person is facing, wherein a brightness included in the one or more lighting properties decreases when the person is facing towards the vehicle.

10 . The control system of claim 2 , wherein the control system determines the one or more illumination fields and the one or more lighting properties based on one or more user gestures captured by an image sensor of the vehicle.

11 . The control system of claim 2 , wherein the one or more processors are further configured to execute the instructions to cause the control system to:
determine a location of the vehicle; identify, based on the location of the vehicle, a maximum allowed brightness associated with the one or more lighting properties; and limit, based on the maximum allowed brightness, a brightness associated with the one or more lighting properties.

12 . The control system of claim 2 , wherein the one or more processors are further configured to execute the instructions to cause the control system to:
identify, based on a location of the vehicle, allowed color temperatures associated with the one or more lighting properties; and limit, based on the allowed color temperatures, a color temperature associated with the one or more lighting properties.

13 . The control system of claim 2 , wherein the one or more processors are further configured to execute the instructions to cause the control system to:
determine, based on a time of day, a color temperature associated with the one or more lighting properties.

14 . The control system of claim 13 , wherein the one or more processors are further configured to execute the instructions to cause the control system to:
decrease the color temperature when the time of day at a location of the vehicle transitions from daytime to nighttime; or increase the color temperature when the time of day at the location of the vehicle transitions from nighttime to daytime.

15 . The control system of claim 14 , wherein the one or more processors are further configured to execute the instructions to cause the control system to:
determine the color temperature based on ambient lighting conditions captured by a sensor of the vehicle.

16 . The control system of claim 2 , wherein the one or more processors are further configured to execute the instructions to cause the control system to:
receive, by the one or more sensors, one or more signals from a second mobile device in wireless communication with the vehicle; modify the lighting mode based on a second area associated with a location of the second mobile device; and determine, based on the modified lighting mode and the location of the second mobile device, additional illumination fields and lighting properties.

17 . A control system, comprising:
one or more memories storing instructions; and one or more processors coupled to the one or more memories and configured to execute the instructions to cause the control system to:
determine, via one or more sensors, a location of a device in wireless communication with a vehicle;
identify a lighting mode for illuminating an area associated with the location of the device; and
control one or more lights of the vehicle based on the lighting mode.

18 . The control system of claim 17 , wherein the one or more processors are further configured to execute the instructions to cause the control system to:
determine, based on the lighting mode and the location of the device, one or more illumination fields and one or more lighting properties, wherein controlling the one or more lights is further based on the one or more illumination fields and the one or more lighting properties.

19 . A method comprising:
determining, via one or more sensors of a vehicle, a location of a mobile device in wireless communication with the vehicle; identifying a lighting mode for illuminating an area associated with the location of the mobile device; and controlling one or more lights of the vehicle based on the lighting mode.
