A spoiler mechanism (13) for a vehicle (10) includes a spoiler (16) that has a stowed position and first and second deployed positions. An actuator (22) is configured to move the spoiler (16) though the stowed and first and second deployed positions in response to a command. A multi-link assembly (20) is interconnected by pivot points. The multi-link assembly (20) is operatively connected to the spoiler (16). In the first deployed position at least three pivot points are aligned with one another in a plane and provide a first geometrically locked position. In the second deployed position a second geometrically locked position is provided in which a link of the multi-link assembly (20) abuts another structure.

An adjustable rear bumper spoiler system for a vehicle controls air turbulence by driving the air spoiler device so that the vehicle can be pressed downwards during high-speed driving. The adjustable rear bumper spoiler system also controls air turbulence by driving flap devices so that the vehicle body is pressed downwards with respect to the turning direction during turning. This consequently improves the driving performance and driving reliability of the vehicle.

A system and method for controlling deployment of a vehicle air dam that include receiving vehicle data associated with a vehicle operating condition. The system and method also include analyzing the vehicle data to determine if an elevated engine load condition is present to implement a normal air dam deployment mode or a prohibitive air dam deployment mode. The system and method further include controlling an actuator associated with the vehicle air dam to deploy or retract the vehicle air dam based on the implementation of the normal air dam deployment mode or the prohibitive air dam deployment mode.

An active rear airfoil arrangement (10) for a trailing area of a vehicle having a turbulence creating area. The arrangement (10) is for connection with a static rear horizontal spoiler (20) associated with the rear portion of a vehicle and includes an active rear horizontal spoiler (30a, 30b, 30c). The active rear horizontal spoiler (30a, 30b, 30c) moves to a deployed position and forms a flow passage (48a, 48b, 48c, 48d) that extends horizontally across the top of a liftgate (12). In another aspect of the invention the active rear airfoil arrangement (10) includes vertical left and right active spoilers (32a,32b; 36a,36b) that move to create a flow passage (74,76,88,90) on the left side and right side of a liftgate (12).

An active aerodynamic system for a vehicle includes a movable exterior component disposed over a force sensor that is responsive to an aerodynamic force applied to the exterior surface, and a plurality of two or more linear actuators configured to move the movable exterior component responsive to the force applied to the exterior surface. A controller is configured to detect the aerodynamic force applied to the movable exterior component and to command the linear actuators to move the movable exterior component responsive to the aerodynamic force applied thereto. The controller may take into account other factors, such as vehicle speed, in determining a setting for the position of the movable exterior component and/or for determining a desired amount of aerodynamic force that the movable exterior component should have.
