Patent attributes
An aerodynamic control system for vehicles may improve aerodynamic performance of a vehicle and enhance fuel efficiency and driving stability of the vehicle. The aerodynamic control system includes a diffuser combined with a rear bumper at an ascending position so as to constitute part of a bumper surface of the rear bumper and separated from the rear bumper at a descending position so as to pass air exhausted from a lower part of the vehicle to a rear part of the vehicle along upper and lower surfaces of the diffuser, and a diffuser driving unit that connects a vehicle frame panel in a front of the rear bumper to the diffuser, supporting the diffuser on the vehicle frame panel, and adjusting upward and downward movement of the diffuser and the angle of the diffuser.
