An alternative fuel vehicle having a fuel economy control module with
associated logic that allows the vehicle to operate in a fuel economy
mode based on a desired fuel economy preference. The fuel economy control
logic is in electrical communication with a vehicle system controller
(VSC) and may be integrally formed as a sub-module within the VSC. A fuel
economy control switch controlled by the fuel economy control logic
toggles between an on and an off position to enable or disable a fuel
economy mode. A fuel economy control selector allows a user to select a
desired fuel economy mode preference once the fuel economy control switch
is on. The fuel economy mode selected represents a predefined desired
fuel economy preference such as a distance per amount of fuel consumed,
or alternatively, a percentage of a balance between a fuel economy
operation and a fuel performance operation.
