Abstract: A vehicle employing an active aerodynamic control system is described. A method for controlling the active aerodynamic control system includes determining a target acceleration downforce associated with an acceleration request and vehicle speed, determining a target braking downforce associated with a braking request and vehicle speed, and determining a target cornering downforce associated with a cornering request and vehicle speed. A maximum downforce request and a second greatest downforce request of the target acceleration downforce, the target braking downforce, and the target cornering downforce are determined. A preferred front/rear distribution of downforce is determined based upon the maximum downforce request and the second greatest downforce request. The active aerodynamic control system is controlled based upon the preferred front/rear distribution of downforce and the maximum downforce request.

Abstract: A method of controlling an active aerodynamic element for a vehicle includes determining a target position for the active aerodynamic element from a target aerodynamic force, which may be a given value that is provided based on dynamic conditions of the vehicle. The method actuates the active aerodynamic element to the target position and senses an aerodynamic response characteristic of the active aerodynamic element while actuated to the target position. An estimated applied aerodynamic force is determined from the aerodynamic response characteristic, and is compared to the target aerodynamic force. A force error is determined from the comparison of the estimated applied aerodynamic force and the target aerodynamic force, and a modified position for the active aerodynamic element is determined from the force error and the target aerodynamic force. The active aerodynamic element is actuated to the modified position.

Abstract: Systems and methods are provided testing a vehicle braking system. The method includes determining a nominal brake system parameter of the brake system during a braking operation. A first testing brake operation is performed and a first brake system parameter is determined based on the first testing brake operation. A tested brake system parameter is determined based on the first testing system parameter and the tested brake system parameter is compared to the nominal brake system parameter. A brake system compliance suspicion value of the vehicle braking system is then set based on the comparison.

Abstract: A method and system for controlling a vehicle to improve vehicle dynamics are provided. The method includes receiving data from a plurality of sensors which monitor vehicle dynamics by monitoring at least wheel and steering movements associated with a vehicle system used in controlling vehicle dynamics by control outputs from a holistic vehicle control system. Then, estimating states of the vehicle from computations of longitudinal and latitudinal velocities, tire slip ratios, clutch torque, axle torque, brake torque, and slip angles derived from the data sensed by the sensors from the wheel and steering movements. Finally, formulating a model of vehicle dynamics by using estimations of vehicle states with a target function to provide analytical data to enable the model of vehicle dynamics to be optimized and for using the data associated with the model which has been optimized to change control outputs to improve in real-time the vehicle dynamics.

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.

Abstract: A system is configured to control aerodynamics of a vehicle. The vehicle includes a body having a front end facing oncoming ambient airflow. The system includes a vehicle control device for receiving operator input to command a target vehicle dynamic response. A vehicle subsystem adjusts an actual vehicle dynamic response to the operator input. The system also includes an adjustable aerodynamic-aid element and a mechanism for varying the element's position to control movement of the airflow relative to the vehicle. At least one sensor detects the adjusted actual vehicle dynamic response and communicates a feedback signal indicative of the detected vehicle dynamic response to a controller. The controller also determines a target position for the aerodynamic-aid element using the detected adjusted actual vehicle dynamic response and regulates the aerodynamic-aid element to its target position via the mechanism to control the aerodynamics and achieve the target dynamic response of the vehicle.

Abstract: A method can be executed to diagnose an aerodynamic system of a vehicle and includes the following steps: (a) determining, via a controller, an expected downforce acting on an aerodynamic element of a vehicle based, at least in part, on a position of the aerodynamic element relative to a vehicle body of the vehicle; (b) determining, via the controller, a measured downforce based, at least in part, on a signal received from at least one force sensor; (c) determining a deviation, via the controller, based, at least in part, on the expected downforce and the measured aerodynamic force; and (d) controlling, via the controller, the aerodynamic element based, at least in part, on the deviation.
