US Patent 10315711 Vehicle ride-height dependent control of air deflector

A system is configured to control aerodynamics of a vehicle. The vehicle includes a vehicle body having a first end facing an ambient airflow when the vehicle is in motion relative to a road surface and a second end arranged opposite the first end. The system includes an air deflector moveably mounted to the vehicle body. The system also includes a mechanism configured to selectively vary a height of the deflector relative to the road surface and a position of the deflector relative to the vehicle body. The system additionally includes a controller configured to determine a ride-height of the vehicle and correlate the determined vehicle ride-height to a target height of the deflector relative to the road surface. The controller is further configured to regulate the mechanism to select the target height of the deflector relative to the road surface to thereby control the aerodynamics of the vehicle.
