Abstract
Methods and systems of an active aerodynamic wheel cap device are provided. The active aerodynamic wheel cap device can be mounted to a vehicle wheel and configured to actuate from a flap-open to a flap-closed state. The flap-open state provides an air vent path from an outer portion of a wheel to an internal component of the wheel, especially at low speeds or during braking. The flap-closed state provides a substantially gapless aerodynamic cap for the wheel of the vehicle at highway speeds or during acceleration. The actuation of the active aerodynamic wheel cap device may be based on an all-mechanical controlled centripetal force movement mechanism.
