Description

Multi-motion Spoiler Assembly and Method for Controlling the Same The present invention relates to a spoiler assembly and a control method for improving the aerodynamic performance of a vehicle by controlling airflow mounted on the rear end of the vehicle, and more specifically, to a multi-motion spoiler assembly and a control method for the same that is capable of adjusting the vertical angle and length. A spoiler is installed at the rear of the vehicle to control the vehicle's aerodynamic performance by changing the airflow. The spoiler is positioned in the width direction of the vehicle and is formed in a wing shape. The spoiler is mounted in a fixed form to control airflow, but recently, by adjusting the angle of the spoiler, downforce is increased or drag is reduced. When the angle of the spoiler is changed, the lift and drag of the spoiler are changed. For example, in situations requiring cornering or straight-line stability, the angle of the spoiler is adjusted to be inclined toward the ground to increase downforce, and when driving focused on fuel efficiency or energy efficiency, the angle of the spoiler is adjusted to be parallel to the ground to reduce drag. The spoiler according to this prior art adjusts the angle of the spoiler from a state parallel to the ground to an upward angle as it moves toward the rear end. Consequently, it was difficult to control the aforementioned spoiler to be inclined downward, so additional drag reduction could not be expected. Furthermore, while increasing the length of the aforementioned spoiler could lead to additional aerodynamic improvements, in some vehicles, it was not possible to adjust the length to actually increase it, as it could only be moved towards the rear.
