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.

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 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: An automotive vehicle includes a steering system and a steering wheel configured to control the steering system. The vehicle additionally includes a dynamic vehicle balance control system configured to modify a yaw rate of the vehicle during a drive cycle to modify understeer behavior. The vehicle also includes a sensor configured to detect an operator force applied to the steering wheel. The vehicle further includes a controller. The controller is configured to, in response to a detected operator force applied to the steering wheel, command the dynamic vehicle balance control system to modify the yaw rate of the vehicle.

CPC classification number: B62D35/005 , B62D35/02
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 system is configured to control aerodynamics of a vehicle. The vehicle includes a vehicle body having a front end facing an ambient airflow when the vehicle is in motion relative to a road surface. The system includes an adjustable aerodynamic-aid element mounted to the vehicle body. The system also includes a mechanism configured to vary a position of the adjustable aerodynamic-aid element relative to the vehicle body and thereby control movement of the airflow. The system additionally includes a sensor configured to detect a height of the vehicle body relative to a predetermined reference frame and a controller configured to receive a signal from the sensor indicative of the detected vehicle body height. The controller is also configured to determine a ride-height of the vehicle using the detected vehicle body height and to regulate the mechanism in response to the determined ride-height to control aerodynamics of the vehicle.

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.
