Claim:
1. A controller for controlling fuel consumption in an internal combustion engine of a vehicle having a driver-actuated accelerator pedal, comprising: an economy fueling mode activation module configured to receive a throttle input value and determine whether the throttle input value falls within defined limits, the throttle input value being controllable by a driver of the vehicle via positioning of the accelerator pedal, wherein the economy mode activation module is configured to activate an economy fueling mode in response to determining the throttle input value falls within the defined limits for a defined amount of time while the internal combustion engine is operating under a standard fueling mode, the economy fueling mode requiring less fuel consumption than the standard fueling mode, wherein the economy mode activation module is an acceleration economy mode activation module and the throttle input value corresponds with rates of change of the position of the accelerator pedal; and a standard fueling mode activation module configured to receive the throttle input value and determine whether the throttle input value falls within the defined limits, wherein the standard fueling mode activation module is configured to activate the standard fueling mode in response to determining the throttle input value does not fall within the defined limits for the defined amount of time while the internal combustion engine is operating under the economy fueling mode.
