Abstract

The invention relates to a variable aerodynamic system for a vehicle. The system includes an active air skirt, an active rear spoiler and an active rear bumper spoiler. When the vehicle is running, when the controller receives the information obtained by the detector and When the information is compared with the pre-input conditions and it is determined that the obtained information satisfies the pre-input conditions, the active air skirt, the active rear spoiler, and the active rear bumper spoiler are selected and deployed by the controller. one or more of . The height from the end of the front bumper to the center of the front wheel is within a predetermined value.

Description

technical field [0001] The present invention relates to vehicles, and more particularly to variable aerodynamic systems for vehicles. Background technique [0002] Generally, when a vehicle travels on a road at high speed, a drag force is generated that is a drag force proportional to the vehicle's speed and area, and lift is generated on the vehicle by the air flowing over the vehicle body, thereby lifting the vehicle . [0003] The top of the vehicle is curved while the bottom is flat. Thus, the velocity of air flowing over the top of the vehicle is greater than the velocity of air flowing under the bottom, creating a pressure differential between the top and bottom of the vehicle, thereby imparting lift to the vehicle. [0004] In order to solve this problem, in the prior art, a rear spoiler is installed on the roof panel or tailgate of a truck or a sports utility vehicle (SUV), or a fixed spoiler is installed on the trunk lid of an ordinary vehicle. The spoiler, which...
