Abstract: A splitter system for a vehicle includes a splitter body having a first splitter body side-section and a second splitter body side-section. The vehicle includes a vehicle body arranged along a longitudinal body axis and having a first vehicle body end configured to face incident ambient airflow. The splitter body is mounted at the first vehicle body end to generate an aerodynamic downforce thereon when the vehicle is in motion. A mechanism is configured to selectively and individually shift each of the first splitter body side-section and the second splitter body side-section relative to the first vehicle body end. The shifting of the splitter body side-sections by the mechanism in turn adjusts the aerodynamic downforce generated by the splitter body side-sections on the first vehicle body end.

Abstract: A vehicle includes a vehicle body arranged along a longitudinal axis and having 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 mounted to the vehicle body. The spoiler assembly includes a spoiler body arranged perpendicular to the longitudinal axis. The spoiler assembly also includes a mechanism configured to vary a position of the spoiler body relative to the first vehicle body end. Such varying of the position of the spoiler body relative to the first vehicle body end is intended to control a movement of the ambient airflow relative to the vehicle body.

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.
