System and method for indicating an efficiency level of energy usage by an automotive vehicle
First Claim
1. A system for indicating to a passenger an efficiency level of energy usage by an automotive vehicle with a passenger compartment, the system comprising:
- a computer-readable storage medium;
a controller in communication with the storage medium, the controller being configured to receive a plurality of energy usage signals, to process the energy usage signals to obtain indications of energy usage amounts that the passenger can control while maintaining a given operating mode of the automotive vehicle, and to determine the efficiency level of energy usage by the automotive vehicle based on the energy usage amounts for the given operating mode of the automotive vehicle;
an interior-lighting system in electrical communication with the controller to illuminate at least a portion of the passenger compartment with ambient light having defined characteristics including a luminance and a color, at least one of the characteristics of the ambient light indicating the efficiency level; and
a display unit in electrical communication with the controller to display for the passenger a graphical representation of the efficiency level of the automotive vehicle.

Abstract
A system and method is provided for indicating an efficiency level of energy usage by an automotive vehicle to a passenger in the vehicle. The system includes a computer-readable storage medium, a controller, an interior-lighting system, and a display unit. The controller processes energy usage signals to obtain the given operating mode of the vehicle as well as indications of energy usage amounts that the passenger can control. The controller determines the efficiency level of energy usage by the vehicle based on the energy usage amounts and the given operating mode. The interior-lighting system illuminates at least a portion of the passenger compartment with ambient light having defined characteristics including a luminance and a color, the ambient light indicating the efficiency level. The display unit displays a graphical representation of the efficiency level.

16. A method for controlling a vehicle lighting system comprising:
-
receiving input indicative of energy usage; generating an efficiency level based on the energy usage for a given operating mode of a vehicle; controlling illumination of a portion of a vehicle passenger compartment with ambient light based on the efficiency level, the ambient light having defined characteristics including a luminance and a color; and displaying a graphical representation of at least one of the energy usage amounts relative to a graphical measure to display the graphical representation of the efficiency level, wherein changing the one energy usage amount changes the graphical representation of the energy usage amount relative to the graphical measure. - View Dependent Claims (17, 18)
