Fairing for a vehicle

Adjustable aerodynamic devices are controlled to control the drag on a vehicle. In one form, control is accomplished in response to pressure from a plurality of pressure sensors. In another form, control is accomplished in response to air movement measurements, such as of wind speed and direction at a location that a vehicle has yet to reach. In another form, the position and location of air vortices between a cab and trailer can be determined and adjusted to adjust the drag by controlling aerodynamic devices.

Dynamically adjustable aerodynamic vehicle devices

Mechanisms are described for selectively closing grille and/or bumper openings. These mechanisms may be operated in response to one or more vehicle parameters. Closure mechanism control signals may be delivered to such mechanisms along a vehicle databus. In addition, vehicle parameters used in determining the control of such mechanisms may be sensed and provided along the databus to a controller which then processes the parameter information for determining whether to open or close the vehicle grille closing mechanism and/or the vehicle bumper opening closing mechanism.

Selective closing of at least one vehicle opening at a front portion of a vehicle
