Abstract: Data from a vehicle subsystem are input to a machine learning program trained to output a plurality of temporal pattern vectors. The temporal pattern vectors are input to an attention-based encoder trained to output a latent feature matrix. Each of the latent feature vectors is assigned to a respective one of a plurality of clusters. Based on the assigned clusters, an operation value is output to a controller of the vehicle subsystem.

Abstract: A vehicle hitching assistance system includes a controller acquiring image data from the vehicle and identifying a trailer within a specified area of the image data and then identifying a coupler of the trailer. The specified area is less than a total field of the image data. The controller then outputs a steering signal to the vehicle to cause the vehicle to steer to align a hitch ball of the vehicle with the coupler.

Abstract: A driver assistance system for a vehicle having a hitch includes a trailer detection system, a steering system, and a controller. The controller determines that a trailer is not coupled with the hitch and outputs a reverse hitching path control signal to the steering system and determines that the trailer is coupled with the hitch and outputs a trailer backing path control signal to the steering system.

Abstract: A method for identifying a trailer connection for a vehicle includes storing a plurality of connection configurations as saved configurations. The connection configurations identify a hitch compatibility of a coupler of a trailer to a hitch assembly. The method further comprises capturing image data depicting the hitch assembly and processing the image data. Based on the processing of the image data, the method further identifies a detected hitch configuration of the hitch assembly as a first hitch configuration of the saved configurations.

Abstract: A vehicle system comprises a hitch assembly mounted on a vehicle, a display, and a controller. The controller is configured to access a saved configuration for the hitch assembly and display the saved configuration on the display. The controller is further configured to receive a selection of the saved configuration and program a characteristic of the hitch assembly based on the selection.

Abstract: Certain driver-assist features of a vehicle require incredibly precise longitudinal control of the vehicle. Achieving the precise control requires up-to-date knowledge of performance parameters of a brake system of the vehicle, which may vary extensively based on a wide set of influences outside the control of the brake system. The present disclosure proposes techniques to determine these parameters, for example, by stopping the vehicle early in maneuvering in order to study the brake performance, so that precise longitudinal control of the vehicle may be realized.

Abstract: Systems and methods for operating a hybrid powertrain of a vehicle that includes an engine and a motor/generator are described. The systems and methods may judge whether or not to generate an engine start request when an engine is stopped in response to present vehicle operating conditions and predicted vehicle operating conditions.

Abstract: A hybrid electric vehicle having a powertrain including an engine and an electric machine, and controllers configured to derate powertrain output torque below a nominal maximum to a fault-torque limit, in response to a vehicle fault or issue. The vehicle and controllers are also configured to transiently increase powertrain torque output above the fault-torque limit in response to a torque demand that exceeds the limit, and which is needed to enable a predicted vehicle maneuver. The controller also establishes a predicted duration for the predicted interim vehicle maneuver and for override of the fault-torque limit and delivery of the additional torque from the torque-demand signal and other signals. The predicted duration includes a time span to maneuver through roadway obstacles and traffic, but does not exceed a limited operation time or a limited power output established by the controller from the vehicle issue or fault identified by the fault signal.

Abstract: A vehicle hitch assistance system includes a steering system and a controller. The controller acquires position data for a coupler of a trailer, derives a vehicle path to position a center of a hitch ball of the vehicle at an interference offset past a centerline of the coupler in a driving direction of the vehicle path, and outputs a steering control signal to the steering system to maintain the vehicle along the path.

Abstract: A vehicle system comprises a hitch ball mounted on a vehicle and a controller configured to identify a coupler position of a trailer. The controller is further configured to control motion of the vehicle aligning the hitch ball with the coupler position and monitor a height of the coupler relative to the hitch ball. In response to the coupler height being less than a height of the hitch ball, the controller is configured to stop the motion of the vehicle.
