摘要： 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.

摘要： A vehicle includes a system and method of modeling and controlling a traction of a wheel of the vehicle. The system includes an observer, a predictive controller and an online solver. The observer receives a dynamic model parameter of the wheel and determines an estimate of a wheel velocity and an uncertainty in the wheel velocity using a non-linear model of the wheel. The predictive controller determines an average gain and differential gain from the estimate of the wheel velocity and the uncertainty in the wheel velocity. The online solver calculates a motor torque and a wheel brake torque for increasing the traction of the wheel with a road based on the average gain and the differential gain. The motor torque and the wheel brake torque are applied at the vehicle.

摘要： 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.
