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 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 toe optimization system for a vehicle with first and second rear wheels defining a rear toe angle. The vehicle includes a plurality of sensors and first and second actuators operatively connected to the first and second rear wheels, respectively, for varying the rear toe angle. A controller has a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for controlling the rear toe angle. Execution of the instructions by the processor causes the controller to select one of a plurality of vehicle states. Each of the plurality of vehicle states has a respective toe setting. The controller is configured to actuate the first and second actuators to vary the rear toe angle to the respective toe setting. By actively controlling the rear toe angle, the agility and stability of the vehicle can be optimized according to the specific vehicle state.
