Abstract
According to one embodiment, an apparatus for controlling fuel consumption in an internal combustion engine of a vehicle having a driver-actuated accelerator pedal includes an economy mode activation module and a standard fueling module. The economy mode activation module is configured to compare throttle input data with defined limits. The throttle input data is controllable by a driver of the vehicle via positioning of the accelerator pedal. The economy mode activation module is configured to control the fuel consumption of the internal combustion engine via an economy fuel map if the throttle input data falls within the defined limits for a defined amount of time. The standard fueling mode activation module is configured to control the fuel consumption of the internal combustion engine via a standard fuel map if the throttle input data does not fall within the defined limits for the defined amount of time.
