Abstract: A method for lane centering control of a host vehicle that is towing a trailer includes: determining in real time, by a controller of the host vehicle, a radius of curvature of a turn, wherein the host vehicle is approaching the turn; determining, by the controller, a trailer required offset based on the radius of the curvature of the turn to maintain the host vehicle and the trailer in a lane while the host vehicle and the trailer move along the turn; and controlling the host vehicle using the trailer offset to maintain the host vehicle and the trailer in a lane while the host vehicle and the trailer move along the turn. The method also allows the host vehicle to avoid encroaching vehicles.

Abstract: A vehicle and a system and method of operating a vehicle. The system includes a processor. The processor learns a driver's behavior of a driver of the vehicle as the driver navigates a road segment, creates a behavior policy based on the driver's behavior and a threshold associated with the road segment, and controls the vehicle to navigate the road segment using the behavior policy.

Abstract: An autonomous vehicle and a system and method of operating the autonomous vehicle. The system includes a processor. A driver-applied steering torque is received at the autonomous vehicle while the autonomous vehicle is following an initial target path via a path tracking program. The processor receives the driver-applied steering torque and allows a driver to adjust a path of the autonomous vehicle from the initial target path to a final target path determined through the driver-applied steering torque.

Abstract: An automotive vehicle includes at least one sensor configured to detect a lane marking proximate the vehicle, and to detect velocity, acceleration, and yaw rate of the vehicle. The vehicle also includes a controller in communication with the at least one sensor and configured to selectively control a steering intervention system in a first mode and a second mode. The controller is configured to calculate a plurality of lane departure estimations at a corresponding plurality of time instances, arbitrate among the plurality of lane departure estimations to calculate a predictive time to lane departure, calculate a lane departure confidence value associated with the predictive time to lane departure, and, in response to the confidence value exceeding a first threshold and the predictive time to lane departure being below a second threshold, control the steering intervention system in the second mode.

Abstract: Methods and systems are provided for controlling a vehicle comprising an Electric Power Steering System (EPS). In an embodiment, a method includes learning, by a processor, a non-linearity of a boost factor associated with the EPS; determining, by the processor, a deboost factor based on an inverse relationship of the learned non-linearity of the boost factor associated with the EPS; and generating, by the processor, a steering command to the EPS based on the deboost factor.

Abstract: Methods and systems are provided for estimating vehicle parameters of a vehicle. A maximum desired vehicle acceleration and a minimum excitation acceleration in a first direction are determined. The minimum excitation acceleration is associated with generating an estimated vehicle parameter. A first control input for transmission to an advanced driver assistance system (ADAS) to apply a temporary excitation acceleration that is greater than the minimum excitation acceleration and less than the maximum desired vehicle acceleration is generated. The estimated vehicle parameter is generated using a vehicle parameter estimation observation model based on vehicle data received from at least one vehicle sensor. The vehicle data is generated in response to the application of the temporary excitation acceleration to the vehicle. The estimated vehicle parameter is transmitted to the ADAS of the vehicle for replacement of a previous vehicle parameter at the ADAS with the estimated vehicle parameter.

Abstract: Vehicles and related systems and methods are provided for predicting a future maneuver expected to be executed by a driver. One method involves determining a combined probability for a potential maneuver based on constituent probabilities corresponding to different vehicle state variables, and environmental conditions using one or more tuning parameters specific to the respective combination of maneuver and vehicle state variable, determining an adjusted probability for the potential maneuver based at least in part on the combined probability and one or more contextual state variables corresponding to a current operating context for the vehicle, adapted to driver behavior and driving style, identifying the potential maneuver as an expected maneuver to be executed by a driver of the vehicle based on the adjusted probability, and automatically initiating one or more actions in a manner that is influenced by the expected maneuver.

Abstract: A system and method for a vehicle control adaptation to a crosswind and a wind gust including a controller situated within a vehicle to receive wind data inputs. The wind data inputs are based on a location of the vehicle and include a sustained wind velocity, a sustained wind direction, and a wind gust level. The controller further receives vehicle measurement data from one or more sensors situated within the vehicle and determines a wind impact on the vehicle based on the wind data inputs and the vehicle measurement data. The controller further compensates for the wind impact by a feedforward control in response to a low bandwidth component of the wind data inputs and by a feedback control in response to a high bandwidth component of the wind data inputs. The controller generates a feedback and/or a control based on the wind impact.
