Abstract: Methods, systems, and vehicles are provided for controlling a direction of a vehicle using aerodynamic forces. A rudder is positioned on a body of the vehicle. A control system is coupled to the rudder, and comprises a detection unit and a processor. The detection unit is configured to obtain sensor data for the vehicle. The processor is coupled to the detection unit, and is configured to at least facilitate obtaining a measured yaw rate for the vehicle using the sensor data, determining an intended yaw rate for the vehicle using the sensor data, and moving the rudder based at least in part on a comparison between the measured yaw rate and the intended yaw rate.

Abstract: A dive-plane system for a vehicle includes first and second dive-planes. The vehicle includes a vehicle body having a first vehicle body end facing oncoming ambient airflow when the vehicle is in motion and first and second lateral body sides. The first dive-plane is mounted to the first lateral body side proximate the first body end to generate an aerodynamic downforce on the first body end at the first lateral body side. The second dive-plane is mounted to the second lateral body side proximate the first body end and configured to generate an aerodynamic downforce on the first body end at the second lateral body side. The dive-plane system also includes a mechanism configured to selectively and individually shift each of the first and second dive-planes relative to the vehicle body to adjust a magnitude of the aerodynamic downforce generated by each dive-plane on the first vehicle body end.

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 splitter system for a vehicle includes a splitter body having a first splitter body. The vehicle includes a vehicle body arranged along a longitudinal body axis and having a first vehicle body end configured to face oncoming ambient airflow. The splitter body is moveably mounted at the first vehicle body end and generates an aerodynamic downforce on the first vehicle body end when the vehicle is in motion. The splitter system also includes a mechanism configured to selectively translate the splitter body along the longitudinal body axis away from the first vehicle body end into the incident airflow and toward the first vehicle body end out of the incident airflow. The translation of the splitter body by the mechanism in turn adjusts the aerodynamic downforce generated by the splitter body on the first vehicle body end.

Abstract: The vehicle has a vehicle body including a first body end facing incident ambient airflow, a second body end opposite of the first body end, an underbody section spanning a distance between the first and second body ends, and vehicle subsystem arranged proximate the underbody section. A panel is moveably mounted to the underbody section and configured to regulate access of an underbody portion of the incident airflow to the subsystem. A mechanism is configured to shift the panel to selectively expose at least a part of the subsystem to the underbody portion of the incident airflow and shield the subsystem to thereby enhance aerodynamics of the vehicle body. A sensor detects a vehicle operating parameter and communicates the detected operating parameter to a controller. The controller is configured to regulate the mechanism and thereby shift the panel in response to the detected vehicle operating parameter.

Abstract: A method is provided for use with a vehicle collision system. The method includes identifying one or more objects along a side surface of the vehicle, determining a highest threat object based on the vehicle's trajectory relative to the one or more identified objects, calculating a time-to-collision between the highest threat object and the side surface of the vehicle, determining a remedial action by comparing the time-to-collision with at least one threshold, and initiating the remedial action to avoid a collision between the side surface of the vehicle and the highest threat object.

Abstract: A method can be executed to diagnose an aerodynamic system and includes the following steps: (a) determining, via a controller, a first expected downforce acting on an aerodynamic element of a vehicle based, at least in part, on a current position of the aerodynamic element relative to a vehicle body of the vehicle, wherein an electric motor is operatively coupled to the aerodynamic element; (b) determining, via the controller, a second expected downforce acting on the aerodynamic element of the vehicle based, at least in part, on an electrical current used to move the electric motor in order to move the aerodynamic element from the current position to another position; (c) determining a deviation, via the controller, based on the first expected downforce and the second expected downforce; and (d) controlling, via the controller, the aerodynamic element based, at least in part, on the deviation.

Abstract: A vehicle includes a vehicle body arranged along a longitudinal body axis in a body plane 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 also includes an active hybrid spoiler assembly mounted to the vehicle body and configured to control a movement of the ambient airflow along the longitudinal body axis. The spoiler assembly includes at least one stanchion mounted to the vehicle body, and first and second wing-shaped side-sections moveably connected to the stanchion(s). The spoiler assembly further includes a mechanism configured to selectively and individually shift each of the first wing-shaped side-section and the second wing-shaped side-section relative to the at least one stanchion to thereby adjust a magnitude of the aerodynamic downforce generated by each of the first wing-shaped side-section and the second wing-shaped side-section on the vehicle body.
