Abstract: A vehicle includes a motor for propelling the vehicle and at least one active aerodynamic element configured to generate a variable amount of aerodynamic downforce on the vehicle when the vehicle is in motion. The vehicle also includes at least one driver input sensor configured to detect a driver input and generate a feedforward signal indicative of a desired behavior of the vehicle. The vehicle additionally includes a controller in communication with the at least one driver input sensor and the at least one active aerodynamic element and configured to regulate the at least one active aerodynamic element at least partially in response to the feedforward signal. A method for controlling such an active aerodynamic element and a system for controlling an aerodynamic downforce on a vehicle are also disclosed.

Abstract: A multi-wheeled vehicle employing an active aerodynamic control system is described. A method for controlling the vehicle and the active aerodynamic control system includes determining states of parameters related to ride and handling of the vehicle, and determining a current tractive effort based upon the states of parameters related to ride and handling of the vehicle. A desired tractive effort is determined based upon an operator desired acceleration, and an available tractive effort is determined based upon an available downforce transferable to the wheels from the active aerodynamic control system and downforces of the wheels. The active aerodynamic control system controls the downforce on one of the wheels to control the current tractive effort responsive to the desired tractive effort.

Abstract: A vehicle includes a vehicle body arranged in a body plane and having a longitudinal body axis. The vehicle also has a first vehicle body end configured to face oncoming ambient airflow when the vehicle is in motion relative to a road surface. The vehicle additionally includes a spoiler assembly. The spoiler assembly includes a wing-shaped body arranged along a spoiler axis that is parallel to the body plane and configured to control a movement of the ambient airflow along the longitudinal body axis. The spoiler assembly also includes a stanchion connecting the wing-shaped body to the vehicle body. The spoiler assembly additionally includes a mechanism configured to rotate the wing-shaped body to thereby vary an angle of the spoiler axis relative to the longitudinal body axis.
