Abstract

A brightness management system for a vehicle includes a network providing wireless communication for a vehicle environment, a mobile device in the vehicle environment and including a first light detector for detecting a first light level at a first location of the mobile device, at least one vehicle display coupled with the vehicle and having at least one brightness level, and control circuitry communicatively coupled with the mobile device and the at least one vehicle display via the network. The control circuitry is configured to detect the first location of the mobile device in the vehicle, receive an indication of the first light level from the mobile device, and communicate a signal to adjust the at least one brightness level of the at least one vehicle display based on the first location and the first light level.

First claim

What is claimed is:

1. A brightness management system for a vehicle, comprising:
a network providing wireless communication for a vehicle environment;
a mobile device in the vehicle environment and including a first light detector for detecting a first light level at a first location of the mobile device;
at least one vehicle display coupled with the vehicle and having at least one brightness level; and
control circuitry communicatively coupled with the mobile device and the at least one vehicle display via the network, wherein the control circuitry is configured to:
detect the first location of the mobile device in the vehicle;
receive an indication of the first light level from the mobile device; and
communicate a signal to adjust the at least one brightness level of the at least one vehicle display based on the first location and the first light level.

2. The brightness management system of claim 1 , further comprising:
a second light detector that detects a second light level at a second location in the vehicle environment, wherein the control circuitry includes a light mapping module that compares the first light level to the second light level to estimate a lighting gradient of the vehicle environment.

3. The brightness management system of claim 2 , wherein control circuitry is further configured to receive an indication of a use status of the mobile device, wherein the signal to adjust the at least one brightness level is based further on the use status of the mobile device.

4. The brightness management system of claim 3 , wherein the light mapping module is configured to adjust the estimation of the lighting gradient in response to the use status.

5. The brightness management system of claim 2 , wherein the at least one vehicle display includes a first vehicle display in a first passenger zone of the vehicle and a second vehicle display in a second passenger zone of the vehicle, wherein the at least one brightness level includes a first brightness level and a second brightness level each adjustable in response to the lighting gradient.

6. The brightness management system of claim 5 , wherein first vehicle display is coupled to a seating assembly configured to move the first vehicle display between the first passenger zone and another zone, wherein moving the first vehicle display between the first passenger zone and the another zone causes adjustment of the first brightness level.

7. The brightness management system of claim 6 , wherein adjustment of the first brightness level to the another zone is based on a light intensity difference between the first passenger zone and the another zone.

8. The brightness management system of claim 6 , further comprising:
a seat position sensor that detects a position of the seating assembly, wherein the control circuitry is in communication with the seat position sensor and the signal to adjust the at least one brightness level is based further on the position.

9. The brightness management system of claim 1 , further comprising:
an imaging system that monitors the vehicle environment and is configured to detect a glare on a first part of the at least one vehicle display, wherein the signal is based further on the glare on the first part of the at least one vehicle display.

10. The brightness management system of claim 9 , wherein the at least one brightness level includes a first brightness level for the first part of a single vehicle display and a second brightness level for a second part of the single vehicle display separate from the first part, wherein the signal to adjust the at least one brightness level includes an instruction to adjust the first brightness level and the second brightness level independent from adjustment to the first brightness level.

11. A brightness management system for a vehicle, comprising:
a network providing wireless communication for a vehicle environment;
a mobile device in the vehicle environment and including a first light detector for detecting a first light level at a first location of the mobile device;
a second light detector that detects a second light level at a second location in the vehicle environment;
at least one vehicle display coupled with the vehicle and having at least one brightness level; and
control circuitry communicatively coupled with the mobile device, the at least one vehicle display, and the second light detector via the network, wherein the control circuitry is configured to:
detect the first location of the mobile device in the vehicle;
receive an indication of the first light level from the mobile device;
compare, via a light mapping module, the first light level to the second light level to estimate a lighting gradient of the vehicle environment; and
communicate a signal to adjust the at least one brightness level of the at least one vehicle display based on the lighting gradient.

12. The brightness management system of claim 11 , wherein control circuitry is further configured to receive an indication of a use status of the mobile device, wherein the signal to adjust the at least one brightness level is based further on the use status of the mobile device.

13. The brightness management system of claim 12 , wherein the light mapping module is configured to adjust the estimation of the lighting gradient in response to the use status.

14. The brightness management system of claim 11 , wherein the at least one vehicle display includes a first vehicle display in a first passenger zone of the vehicle and a second vehicle display in a second passenger zone of the vehicle, wherein the at least one brightness level includes a first brightness level and a second brightness level each adjustable in response to the lighting gradient.

15. The brightness management system of claim 14 , wherein first vehicle display is coupled to a seating assembly configured to move the first vehicle display between the first passenger zone and another zone, wherein moving the first vehicle display between the first passenger zone and the another zone causes adjustment of the first brightness level.

16. The brightness management system of claim 15 , wherein adjustment of the first brightness level to the another zone is based on a light intensity difference between the first passenger zone and the another zone.

17. The brightness management system of claim 15 , further comprising:
a seat position sensor that detects a position of the seating assembly, wherein the control circuitry is in communication with the seat position sensor and the signal to adjust the at least one brightness level is based further on the position.

18. A brightness management system for a vehicle, comprising:
a network providing wireless communication for a vehicle environment;
a mobile device in the vehicle environment and including a first light detector for detecting a first light level at a first location of the mobile device;
at least one vehicle display coupled with the vehicle and having at least one brightness level; and
control circuitry communicatively coupled with the mobile device and the at least one vehicle display via the network, wherein the control circuitry is configured to:
detect the first location of the mobile device in the vehicle;
receive an indication of the first light level from the mobile device;
receive an indication of a use status of the mobile device; and
communicate a signal to adjust the at least one brightness level of the at least one vehicle display based on the first location, the first light level, and the use status of the mobile devi
