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 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 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 chassis control system of a vehicle includes: a first torque source providing torque to a first axle of the vehicle; a second torque source providing torque to a second axle of the vehicle independently of the first torque source; and a vehicle control module controlling the first and second torque sources to transition between a torque redistribution and torque limit control modes based on a wheel torque redistribution threshold, a wheel torque limit of the first axle and/or second axle, and a torque limit of one of the first and second torque sources. The torque redistribution mode refers to when torque is being selectively provided to the first axle by the first torque source and to the second axle by the second torque source. The torque limit control mode refers to when torque to at least one of first axle and the second axle is limited.
