Abstract
A method for active downforce control for a vehicle may include determining an out-of-phase interaction index between a driver of the vehicle and a controller. The controller is configured to control one or more aerodynamic actuators. The method further may include determining one or more active downforce control inputs based at least in part on the out-of-phase interaction index. The method further may include controlling the one or more aerodynamic actuators based at least in part on the one or more active downforce control inputs.
