Abstract: In an exemplary embodiment, a method for controlling a vehicle includes the steps of receiving, by a vehicle controller, sensor data representing a vehicle environment along a projected path of travel of the vehicle from at least one sensor, determining, by the vehicle controller, if the projected path of travel of the vehicle includes an obstacle, determining, by the vehicle controller, if an underbody component of the vehicle will impact the obstacle, and if the underbody component will impact the obstacle, generating, by the vehicle controller, a control signal to move the underbody component from a first position to a second position.

Abstract: Disclosed are self-calibrating load sensor systems for active aerodynamics devices, methods for making or using such load sensor systems, and motor vehicles equipped with a self-calibrating load sensor system to govern operation of the vehicle's active aero device(s). An active aero sensing system includes a load sensor that mounts to the vehicle body, and detects downforces on the vehicle. A memory device stores mapped vehicle downforce data calibrated to the motor vehicle. A vehicle controller receives downforce signals generated by the load sensor, and calculates an average downforce value from these signals. The controller determines if the average downforce differs from a calibrated downforce value retrieved from the memory device. If so, the controller responsively applies an offset value to subsequent downforce signals received from the load sensor, and dynamically controls operation of the active aero device based, at least in part, on these signals modified by the offset value.

Abstract: A duct is configured for a vehicle having a vehicle body arranged along a longitudinal body axis. The vehicle body includes a first vehicle body end configured to face oncoming ambient airflow when the vehicle is in motion, a second vehicle body end opposite of the first vehicle body end. The duct has a fully-enclosed structure in a cross-sectional view perpendicular to the longitudinal body axis. The duct also has a first port positioned to receive a portion of the oncoming airflow and a second port positioned to exhaust the portion of the oncoming airflow from the duct. The first and second ports together with the fully-enclosed structure are configured to generate an aerodynamic downforce on the vehicle body when the vehicle is in motion.

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 system is configured to control aerodynamics of a vehicle. The vehicle includes a vehicle body arranged along a longitudinal axis with a first vehicle body end configured to face incident ambient airflow. The system includes an aerodynamic-aid element mounted to the vehicle body and configured to generate a downforce thereon via controlling the incident ambient airflow. The system also includes an adjustable flap arranged at the aerodynamic-aid element. The adjustable flap is configured to shift relative to the aerodynamic-aid element and thereby control movement of the incident ambient airflow relative to the aerodynamic-aid element. The system additionally includes a mechanism configured to vary position of the adjustable flap relative to the aerodynamic-aid element and thereby vary a magnitude of downforce generated by the aerodynamic-aid element.

Abstract: A vehicle includes an engine generating exhaust gas flow and a vehicle body having a first body end facing oncoming ambient airflow when the vehicle is in motion and an opposite second body end. A vehicle underbody section spans a distance between the first and second body ends. A diffuser disposed at the second body end controls an underbody airflow portion past the second body end. An exhaust duct discharges the exhaust gas via a duct outlet arranged between the underbody section and the diffuser. A first diffuser aperture aligns with the duct outlet for discharging the exhaust gas from the outlet to the ambient. A second diffuser aperture pulls at least a fraction of the underbody airflow over the duct outlet and through the first aperture. The first and second apertures accelerate the pulled underbody airflow to increase a downforce on the vehicle body at the second body end.

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: Disclosed are active variable-width aerodynamic spoiler assemblies, methods for making or for operating such active spoiler assemblies, and vehicles equipped with such active spoiler assemblies. A disclosed active spoiler assembly for modifying the aerodynamic performance of a motor vehicle includes a main body rigidly mounted to the vehicle body, extending transversely across the vehicle. The main body has an elongated construction with opposing longitudinal ends. First and second fins are each movably attached to a respective one of the opposing longitudinal ends of the main body. Also, first and second fin actuators are each attached to the vehicle body and attached to a respective one of the movable fins. The first fin actuator is selectively actuatable to independently move the first fin between respective retracted and extended positions, whereas the second fin actuator is selectively actuatable to independently move the second fin between respective retracted and extended positions.
