Abstract
An aerodynamic control system of a vehicle includes a utilization module that, based on a longitudinal force on a tire in a longitudinal direction and a latitudinal force on the tire in a latitudinal direction, determines a utilization force on the tire of the vehicle and a direction of the utilization force. A maximum module, based on the direction of the utilization force, determines a maximum force of the tire for maintaining traction between the tire and a road surface contacting the tire. A difference module determines a difference between the utilization force on the tire of the vehicle and the maximum force on the tire. An aerodynamic actuator control module selectively adjusts a position of an aerodynamic actuator of the vehicle based on the difference.
