Abstract: A system comprises a computer including a processor and a memory. The memory includes instructions such that the processor is programmed to receive geoindexed detected vehicle event data from at least one vehicle occurring within a predefined time period, normalize the geoindexed detected vehicle event data according to Global Position System (GPS) data corresponding to a geoindex map, and generate an infrastructure recommendation based on the normalized and aggregated geoindexed detected vehicle event data.

Abstract: Systems, methods, and apparatus are provided for providing multi-trailer reverse assistance. In a multi-trailer reverse assistance system in an articulated transport system comprising a lead vehicle, an intermediate trailer, and a final trailer, the reverse assist system includes a controller. The controller is configured to: receive a view of an environment behind the final trailer; cause the view to be displayed in a display screen of a user interface device; receive, via a secondary steering device of the user interface device, a user intended direction of travel of the articulated transport system in reverse to direct the final trailer in a desired direction; continuously calculate controllable steering angles for directing the articulated transport system to direct the final trailer in the desired direction; and control the articulated transport system to direct the final trailer in the desired direction using the calculated controllable steering angles.

Abstract: A method for dampening trailer sway, includes: receiving, by a controller of a vehicle system that is coupled to a trailer, a vehicle speed signal of the vehicle system, wherein the vehicle speed signal is indicative of a vehicle speed of the vehicle system; determining a friction force to be applied to the trailer by an actuator using the vehicle speed of the vehicle system and a graph that establishes a relationship between the friction force to be applied to the trailer and the vehicle speed; and adjusting, by the controller, the graph that establishes the relationship between the friction force and the vehicle speed using the decay rate of the plurality of oscillation amplitudes to create an updated graph.

Abstract: In various embodiments, methods, systems, and vehicle apparatuses are provided. A method for estimating a Hitch Articulation Angle (HAA) using Ultra-Sonic Sensors (USSs) while ensuring quality detected echo signal performance using plausibility filtering, generating at least one set of USS data based on detecting a set of echo signals generated by a plurality of USSs configured about a vehicle coupled to a trailer; determining based on a set of USS data using a selected set of geometric equations in a plausibility filtering process for an arbitrary frontal shape of the trailer; and generating at least one comparison based on at least one set of USS data estimations to a kinematic model at low speeds for ensuring that results of the kinematic model to the HAA associated with the determined trailer shape is based on a pair of detected echo signals that are deemed to have a higher signal performance.

Abstract: Systems for detecting movement of a trailer having a rearward facing camera and linked to a tow vehicle. The systems include taking a first image and a second image with the camera and comparing the images. A first amount of trailer movement is determined between the second image and the first image. The systems may also take additional images and determine a second amount of trailer movement occurring between the additional images. Tracking the first amount and the second amount of trailer movement determines an amount of trailer sway. The determined trailer sway may be compared to a maximum allowable sway and, if the movement is greater than the maximum allowable sway, mitigating sway of the trailer with the tow vehicle.
