System and method for displaying an instantaneous fuel economy of a vehicle
First Claim
1. A display system comprising:
- a controller configured to;
determine an actual instantaneous efficiency value based upon current vehicle operating conditions;
receive information related to a braking system; and
calculate an adjusted instantaneous efficiency value based upon the actual instantaneous efficiency value and the braking system information; and
a display, in communication with the controller, including an instantaneous efficiency indicator indicative of the adjusted instantaneous efficiency value.

Abstract
An information display system and method are provided for displaying an energy efficiency of a vehicle. The vehicle may include an engine and an electric machine that operates to provide torque to propel the vehicle. The vehicle may also include an energy source that provides energy to the electric machine. The information display system may comprise an information display configured to display an efficiency indicator, the efficiency indicator being configured to indicate an efficiency of the vehicle. The information display system may further comprise a controller configured to receive information related to the braking system of the vehicle. The controller further being configured to determine an energy efficiency value based upon the braking system information. The controller may also be configured to transmit the energy efficiency value so that the information display displays the efficiency indicator based upon the energy efficiency value.
