Abstract:
A system is configured to control aerodynamics of a vehicle. The vehicle includes a body having a front end facing oncoming ambient airflow. The system includes a vehicle control device for receiving operator input to command a target vehicle dynamic response. A vehicle subsystem adjusts an actual vehicle dynamic response to the operator input. The system also includes an adjustable aerodynamic-aid element and a mechanism for varying the element's position to control movement of the airflow relative to the vehicle. At least one sensor detects the adjusted actual vehicle dynamic response and communicates a feedback signal indicative of the detected vehicle dynamic response to a controller. The controller also determines a target position for the aerodynamic-aid element using the detected adjusted actual vehicle dynamic response and regulates the aerodynamic-aid element to its target position via the mechanism to control the aerodynamics and achieve the target dynamic response of the vehicle.
