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.

What is claimed is: 1. A fuel economy control system for an alternative fuel vehicle comprising: a fuel economy control module including associated fuel economy control logic that operates to allow a vehicle to operate in a fuel economy mode based on a desired fuel economy preference selected by a user, said alternative fuel vehicle selected from the group consisting of a hybrid electric vehicle and a fuel cell vehicle. 2. The fuel economy control system of claim 1, further comprising: a selectable fuel economy control switch; and a vehicle system controller in electrical communication with the fuel economy control logic, wherein the vehicle system controller and the fuel economy control logic cooperate to control the selectable fuel economy control switch thereby enabling or disabling, respectively a fuel economy mode. 3. The fuel economy control system of claim 2, further comprising a fuel economy control selector in operative electro-mechanical communication with a fuel economy switch, wherein the fuel economy control selector allows a user to select a desired fuel economy mode preference when the fuel economy control switch selected. 4. The fuel economy control system of claim 2, further comprising: a cruise control system having an associated cruise control button, wherein the fuel economy switch is in operative communication with the cruise control button and is turned on or off in accordance with depression of the cruise control button. 5. The fuel economy control system of claim 1, further comprising: a selectable fuel economy control switch that enables or disables a fuel economy mode operation, wherein the fuel economy control switch is controlled in accordance with the fuel economy control logic; and a fuel economy control selector in operative electro-mechanical communication with the fuel economy control switch that operates to allow a user to select a desired fuel economy mode preference when the fuel economy control switch is selected. 6. The fuel economy control system of claim 5, wherein the fuel economy control switch and the fuel economy control selector are in electromechanical communication with and are controlled by fuel control logic to allow a user to select a desired fuel economy mode preference. 7. The fuel economy control system of claim 6, further comprising: a fuel economy selector gauge having an indicator that indicates a fuel economy mode preference that ranges between 100 percent fuel economy and 100 percent vehicle performance. 8. The fuel economy control system of claim 5, wherein the desired fuel economy mode preference comprises: a predefined fuel economy preference of a desired economy value representing a distance per amount of fuel consumed. 9. The fuel economy control system of claim 5, wherein the desired fuel economy mode preference represents a percentage bf a balance between a fuel economy operation and a fuel performance operation. 10. A fuel economy control strategy for an alternative fuel vehicle comprising: providing a fuel economy mode associated with the vehicle; selecting a desired fuel economy preference to operate the vehicle when the vehicle is operating in the fuel economy mode; and operating the vehicle in the fuel economy mode in accordance with the selected desired fuel economy preference, said vehicle selected from the group consisting of a hybrid electric vehicle and a fuel cell vehicle. 11. The fuel economy control system strategy of claim 10, wherein said desired fuel economy preference comprises a value representing a distance per amount of fuel consumed. 12. The fuel economy control system strategy of claim 10, wherein said desired fuel economy preference comprises a value representing a percentage of a balance between a fuel economy operation and a fuel performance operation. 13. A fuel economy control strategy for an alternative fuel vehicle comprising: providing a vehicle system controller for control of all systems within the vehicle; and providing an economy control module having associated economy control logic that cooperates with the vehicle system controller to control fuel economy within said vehicle in accordance with a predefined fuel economy preference, said predefined fuel economy preference comprises at least one of: a value representing a distance per amount of fuel consumed; and, a value representing a percentage of a balance between a fuel economy operation and a fuel performance operation. 14. The fuel control strategy of claim 13, further comprising: determining a cruise control state; determining a state of a fuel economy control switch; determining a desired fuel economy control selected value; using the vehicle system controller to monitor vehicle parameter inputs associated with a fuel economy mode when the state of the fuel economy control switch is on; determining the state of the fuel economy control switch once the system controller has monitored the vehicle parameter inputs; and optimizing active control of the vehicle in accordance with a driver's fuel economy preference when operating in a fuel economy mode and when the fuel economy control switch is one after monitoring the vehicle parameter inputs. 15. The fuel economy control system strategy of claim 14, further comprising: controlling acceleration and deceleration deviations if the deviations exceed a predefined limit. 16. The fuel economy control system strategy of claim 14, further comprising: controlling a vehicle compartment climate in the vehicle in accordance with climate control maps, wherein the climate control maps correlates temperatures associated with an optimal fuel economy mode. 17. The fuel control strategy of claim 13, further comprising: inputting signals into both the vehicle system controller and the fuel economy from each of an accelerator pedal, a cruise control system, a brake pedal, a fuel supply, a temperature climate controller in communication with an air-conditioner and heater system, a fuel economy control switch, a fuel economy control selector, a wheel speed sensor, a battery, auxiliary loads, and an integrated power train. 18.
