  • Patent number: 11919582
    Abstract: In various embodiments, methods, systems, and vehicle apparatuses are provided. A method for lateral control of a steering system includes identifying at least one parameter of at least one lateral control feature that results in an optimized value in an outcome of control for a lateral control feature enabling robustness to an uncertainty; adaptively adjusting an output control signal generated by a vehicle trajectory controller coupled to the steering controller, by quantifying the uncertainty of an uncertain value in a lateral control feature; and sending a control command including at least a torque control or a wheel angle control to compensate for the uncertainty of the at least one uncertain value in the configuration of components of an electronic power steering (EPS) system associated with the vehicle variant by correcting at least one parameter of the at least one lateral control feature.

  • Publication number: 20240067220
    Abstract: Automated driver assistance systems and methods for towing predict vehicle/trailer instabilities and adapt automated driving control to avoid them. A tow-vehicle includes a controller that, through an actuator system, controls speed and/or steering. A map system and/or a sensor system monitor a roadway on which the vehicle is travelling to identify a road profile located ahead of the vehicle over a prediction horizon. A projected trajectory for navigating the vehicle through the road profile over the prediction horizon and considering environmental conditions is determined. Before travel over the road profile, whether the projected trajectory through the road profile will result in exceeding a vehicle dynamic threshold is determined. When the projected trajectory will result in exceeding the vehicle dynamic threshold through the road profile, a control action is determined to prevent instability and optimize driver experience. The vehicle is operated through the road profile using the control action.

  • Publication number: 20230391324
    Abstract: Systems and methods for controlling a vehicle are provided. The systems and methods provide a vehicle dynamics model that relates at least one input vehicle dynamics variable to at least one output vehicle dynamics variable. The systems and methods detect a crosswind impacting the vehicle by detecting a disturbance associated with the vehicle dynamics model caused by the crosswind and adapt control of the vehicle based on the detecting the crosswind impacting the vehicle.

  • Publication number: 20230286550
    Abstract: In accordance with an exemplary embodiment, a method is provided that includes: obtaining sensor data via one or more sensors of a vehicle; determining, via a processor of the vehicle, a driving style of a driver of the vehicle based on use of the sensor data over multiple periods of time; and determining, via the processor, an indication as to whether the driver is attempting to spoof a control system of the vehicle with respect to one or more automated features of the vehicle, based on the sensor data and the style of the driver.
