A deployable fairing for a transport vehicle comprises a flexible, internally pressurizable enclosure supported by a structural frame. The structural frame comprises a plurality of rigid structural members forming at least two subframes that are pivotally coupled to one another and is foldably movable between a collapsed configuration and an expanded configuration. The enclosure moves with the structural frame, unfolds when the structural frame moves into the expanded configuration and folds in upon itself when the structural frame moves into the collapsed configuration. Moving the structural frame into the expanded configuration develops tension on at least part of the outer surface of the enclosure, and movement of the structural frame into the collapsed configuration releases the tension. When the enclosure is internally pressurized while the structural frame is in the expanded configuration, the outer surface of the enclosure is structurally stiff and conforms to a predefined aerodynamic shape.

Deflector device (7) for a motor vehicle wheel (3), comprising at least one aerodynamic region (4, 400, 401) designed to be exposed to an external air flow (IO), the device (7) further comprising an articulated mechanism (21) for moving the at least one aerodynamic region (4, 400, 401) so as to allow the deflector (7) to move from the retracted position to the deployed position, said articulated mechanism (21) comprising a drive member (22), and said articulated mechanism (21) being arranged to move the drive member (22) translationally when the deflector device (7) moves from the retracted position to the deployed position, the deflector device (7) comprising an actuator (19) configured to control the articulated mechanism (21) so as to allow the aerodynamic regions of the deflector to move relative to each other, said deflector device (7) further comprising a security device (50) configured to return said deflector device (7) to the retracted position without intervention by the actuator (19).

An airflow adjusting apparatus includes an airflow generator, a state detector, and a controller. The airflow generator is configured to generate a control airflow to cause the control airflow to join an around-vehicle airflow formed around a vehicle body of a traveling vehicle. The airflow generator is configured to vary a flow direction of the control airflow with respect to a surface of the vehicle body. The state detector is configured to detect a state of the around-vehicle airflow. The controller is configured to vary the flow direction of the control airflow on the basis of the state of the around-vehicle airflow detected by the state detector.

A control system of a vehicle comprising: i) a plurality of adjustable aerodynamic control devices associated with the vehicle; ii) a fuel economy sensor configured to determine a first fuel economy measurement; and iii) an aerodynamic device controller module configured to adjust a first one of the plurality of adjustable aerodynamic control devices and to receive from the fuel economy sensor a second fuel economy measurement. The aerodynamic device controller module stores in an onboard database state information corresponding to settings of the plurality of adjustable aerodynamic control devices if the second fuel economy measurement is an improvement over the first fuel economy measurement.

A vehicle capable of traveling with a embossed surface of a directionality pattern includes a vehicle body and an under cover member. The under cover member is disposed on one or both of a front portion and a rear portion of a lower surface of the vehicle body. The embossed surface of the directionality pattern is formed on a plane portion of the under cover member. The embossed surface of the directionality pattern is configured to accelerate an airflow along a fore-and-aft direction of the vehicle body.

A vehicle with an improved front aerodynamic characteristic includes a front exterior member disposed on a front surface of a vehicle body of the vehicle. The front exterior member includes a front inlet port, a funnel member, and a specially processed surface. The front inlet port is formed in the front exterior member. The front inlet port is configured to draw in an airflow in front of the front exterior member. The funnel member is formed around the front inlet port. The specially processed surface is formed on an inner surface of the funnel member, and has recesses that are arrayed.

Rear fences and a system for deploying said rear fences on a vehicle are described. The rear fences are disposed inboard of and spaced apart from the rear pillars. The rear fences may be folded against the rear panel of the vehicle when retracted and are rotated to a central position in a deployed position. The system includes a deployment control system including controller logic having at least one processor and a memory storing instructions for implementing deployment and retraction of rear fences on a vehicle.

An active front deflector assembly for a vehicle capable of moving between an extended position and a retracted position or any position there between. The active front deflector assembly has a cross member for attaching to an underbody of a vehicle. The frame member also includes a plurality of slip joint connections for connecting to the underbody of the vehicle. The cross member is a fixed link of an actuator link assembly that has an actuator, drive link, floating link and a blade.

A fairing includes a first part including a wall having and a top flange extending from the wall. A second part of the fairing includes a body and a bottom flange extending from the body. The bottom flange is configured to engage the top flange to couple the second part to the first part.

A rigid and aerodynamic device for external protection for motorcycle and bicycle vehicles with 2 to 4 wheels. This removable dome type device is formed by multiple overlapping panels that form an oval shell type structure, which protects both the vehicle and the pilot from external weather conditions and physical damage in the event of a collision.
