Abstract

A method of autonomously controlling interior lighting of an occupied vehicle is provided. The method includes receiving vehicle-to-vehicle information from a nearby vehicle. A controller controls an illumination setting of an interior light of the occupied vehicle based on the vehicle-to-vehicle information.

First claim

What is claimed is:

1. A method of autonomously controlling interior lighting of an occupied vehicle, the method comprising:
receiving vehicle-to-vehicle information from a nearby vehicle; and
a controller controlling an illumination setting of an interior light of the occupied vehicle based on the vehicle-to-vehicle information;
wherein the controller turning the interior light ON if the vehicle-to-vehicle information indicates to the controller that the nearby vehicle is an emergency vehicle and the controller determines that the occupied vehicle is stopped;
wherein an intensity level of the interior light of the occupied vehicle is reduced by the controller if the interior light is ON and the vehicle speed increases.

2. The method of claim 1 , wherein the step of the controller controlling the illumination setting comprises turning an overhead light ON.

3. The method of claim 1 , wherein an intensity level of an instrument panel of the occupied vehicle is reduced if the vehicle speed increases.

4. The method of claim 3 , wherein the intensity level of the instrument panel of the occupied vehicle is increased if the vehicle speed decreases.

5. The method of claim 1 , wherein an intensity level of a display of the occupied vehicle is reduced if the vehicle speed increases.

6. The method of claim 5 , wherein the intensity level of the display of the occupied vehicle is increased if the vehicle speed decreases.

7. A vehicle comprising a lighting control system that autonomously controls interior lights of a vehicle based on driving conditions comprising:
one or more processors;
one or more memory modules communicatively coupled to the one or more processors;
a network interface module configured for vehicle-to-vehicle communication; and
machine readable instructions stored in the one or more memory modules that cause the one or more processors to control an illumination setting of an interior light of the vehicle based on a vehicle-to-vehicle communication;
wherein the one or more processors configured to turn the interior light ON if the vehicle-to-vehicle communication indicates to the controller that the nearby vehicle is an emergency vehicle and the controller determines that the occupied vehicle is stopped;
wherein the controller is configured to reduce an intensity level of the interior light of the occupied vehicle if the interior light is ON and the vehicle speed increases.

8. The vehicle of claim 7 , wherein the one or more processors controlling the illumination setting comprises turning an overhead light ON.

9. The vehicle of claim 7 , wherein an intensity level of an instrument panel of the occupied vehicle is reduced by the one or more processors if the vehicle speed increases.

10. The vehicle of claim 9 , wherein the intensity level of the instrument panel of the occupied vehicle is increased by the one or more processors if the vehicle speed decreases.

11. The vehicle of claim 7 , wherein an intensity level of a display of the occupied vehicle is reduced by the one or more processors if the vehicle speed increases.

12. The vehicle of claim 11 , wherein the intensity level of the display of the occupied vehicle is increased by the one or more processors if the vehicle speed decreases.
