NOVELTY - The system has a fuel economy control module with a fuel economy control logic operating to allow a vehicle e.g. fuel cell vehicle, to operate in a fuel economy mode based on a desired fuel economy preference selected by a customer. A fuel economy control selector e.g. button, is in operative electromechanical communication with a fuel economy control switch that operates to allow the user to select a desired fuel economy mode preference e.g. distance per amount of fuel consumed, when the fuel switch is selected. A vehicle system controller is in electrical communication with the logic.    USE - Fuel economy control system for an alternative fuel vehicle e.g. electric vehicle, hybrid electric vehicle e.g. series hybrid electric vehicle (SREV) and parallel hybrid electric vehicle (PREV), and fuel cell vehicle.    ADVANTAGE - The fuel economy control selector e.g. button, is in operative electromechanical communication with the fuel economy control switch that operates to allow the user to select the desired fuel economy mode preference e.g. distance per amount of fuel consumed, associated with the vehicle e.g. fuel cell vehicle, in an efficient manner when the fuel economy control switch is selected. The utilization of the vehicle system controller prevents large variations in acceleration or deceleration that exceed a predefined deviation limit, thus enabling the vehicle system controller to ensure control over the acceleration or deceleration remains smooth.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a fuel economy control strategy for an alternative fuel vehicle.
