Abstract: A vehicle includes a vehicle body with a first body end configured to face an incident ambient airflow and an underbody section. The vehicle also includes a brake subassembly arranged proximate the underbody section and configured to decelerate the vehicle. An airflow regulation system includes a deflector moveably mounted to the underbody section and configured to regulate an underbody portion of the incident airflow to the brake subassembly. The system also includes a mechanism configured to change a position of the deflector to selectively direct the underbody portion of the incident ambient airflow to the brake subassembly and enhance aerodynamics of the vehicle body. The system additionally includes a first sensor configured to detect a predetermined operating condition of the brake subassembly. Furthermore, the system includes a controller configured to regulate the mechanism for selecting the deflector's position in response to the detected predetermined operating condition of the brake subassembly.
