Active, aerodynamic controller that describes a method for dynamically controlling airflow using computer controlled movable air dams and airfoils on motor vehicles. It is well known that motor vehicles generally have a great deal of aerodynamic friction also known as drag. Fuel efficiency is greatly affected by a vehicle's aerodynamic drag. Aerodynamic drag is caused by both induced drag and parasitic drag. Parasite drag is somewhat fixed by the overall design and shape of a vehicle. Parasite drag is caused primarily by the laminar flow of air over the smooth surfaces of the vehicle's hood, roof, windows, side mirrors and door panels. Induced drag is much more variable and is primarily created by the differential pressure effects of air flowing over, under and around a vehicle, as well as the relative airflow caused by both ground effect and atmospheric air density and wind. This invention serves to actively minimize the effects of induced drag thus reducing the amount of fuel used by vehicles fitted with this invention.
