US Patent 10155551 Controller to quickly raise and slowly lower an air dam

A front air dam assembly for a vehicle includes a translatable front air deflecting panel for altering an airflow beneath the vehicle, a deploying mechanism for translating the front air deflecting panel between a raised position and one or more deployed positions, and a rapid raising mechanism for rapidly raising the front air deflecting panel from the one or more deployed positions. A controller in operative communication with the deploying mechanism and the rapid raising mechanism controls the operation thereof. At least one sensor is included for sending a signal indicative of a road or vehicle condition to the controller. A locking mechanism under the control of the controller is provided for locking the front air deflector panel in the raised or the one or more deployed position.
