1. A system for controlling aerodynamics of a vehicle, wherein the vehicle includes a vehicle body arranged along a longitudinal axis and having a first vehicle body end configured to face oncoming ambient airflow, the system comprising:

  • a vehicle control device configured to receive operator input for commanding a target dynamic response of the vehicle;

    a vehicle subsystem configured to adjust an actual dynamic response of the vehicle to the operator input;

    an adjustable aerodynamic-aid element mounted to the vehicle body;

    a mechanism configured to vary a position of the adjustable aerodynamic-aid element relative to the vehicle body and thereby control a movement of the ambient airflow relative to the vehicle body;

    at least one sensor arranged on the vehicle and configured to detect the actual dynamic response of the vehicle adjusted by the vehicle subsystem; and

    a controller programmed to regulate the mechanism and configured to;

    receive a feedback signal from the at least one sensor indicative of the detected adjusted actual dynamic response of the vehicle;

    determine a target position for the adjustable aerodynamic-aid element using the detected adjusted actual dynamic response of the vehicle; and

    set the adjustable aerodynamic-aid element to the target position thereof via the mechanism to control the aerodynamics and achieve the target dynamic response of the vehicle.
