A method of controlling a vehicle-trailer unit includes recording, with an electronic control unit for a trailer assist system, a plurality of maneuvers of the vehicle-trailer unit as each maneuver is executed in an original direction of travel. The method also includes retrieving the recorded plurality of maneuvers in response to an initiating of a tight spot reversal feature for the trailer assist system. The method further includes instructing vehicle systems to perform the retrieved recorded plurality of maneuvers in the reverse order and direction of travel in which they were recorded.

A system for assisting in aligning a vehicle for hitching with a trailer includes an imager outputting image data of a field of view to the rear of the vehicle and a controller identifying at least one of a trailer or a coupler of the trailer within the image data. The controller further determines that the at least one of the trailer or the coupler is outside of a specified area relative to the vehicle and outputs an instruction for movement of the vehicle determined to position the one of the trailer or the coupler within the specified area. Upon determining that the at least one of the coupler and the trailer is within the specified area, the coupler outputs a steering signal to the vehicle to cause the vehicle to steer to align a hitch ball of the vehicle with the coupler.

A method for estimating an effective length of a first vehicle segment of a vehicle combination, the vehicle combination comprising a towing vehicle which is connected to the first vehicle segment via a first articulation joint and a perception sensor mounted on one of the towing vehicle and the first vehicle segment and arranged to obtain an image of the other one of the towing vehicle and the first vehicle segment; the method comprising identifying that the vehicle combination is provided in a first steady vehicle state, identifying that a turning and driving manoeuvre is initiated, identifying when the vehicle combination reaches a second steady vehicle state, determining a time period required for driving the vehicle combination from the first steady vehicle state to the second steady vehicle state, and estimating the effective length by use of the time period, the specific angular change, and the specific speed.

A method and device for stabilizing a tractor vehicle-trailer combination during travel, in which tractor vehicle and trailer are connected via at least one pivot joint, including: ascertaining a setpoint buckling angle for a driving-stable setpoint movement of the combination, and/or a setpoint buckling angle velocity for a driving-stable setpoint movement of the combination, between the combination or between two trailers; ascertaining an actual buckling angle for the effective actual movement of the combination, and/or an actual buckling angle velocity for the effective actual movement of the combination, between the tractor vehicle and trailer or between multiple trailers; ascertaining a deviation between the setpoint and actual buckling angles and/or between the setpoint and actual buckling angle velocities, and if the deviation exceeds a threshold value, generating a control signal to activate at least one vehicle component to control movement of the combination in a direction toward a driving-stable movement state.

A method and system for operating a vehicle's trailer reverse assist system is disclosed, including receiving vehicle sensor system data from one or more sensors supported by the vehicle. Based upon the received vehicle sensor data, a trailer pitch angle and a trailer roll angle of a coupled trailer are estimated relative to the vehicle. Surface unevenness of a surface traversed by the vehicle and the trailer is estimated, based upon the estimated trailer pitch angle and the estimated trailer roll angle. One or more parameters of the trailer reverse assist system or of the tow vehicle are adjusted based upon the estimated road surface variance. The trailer reverse assist system of the tow vehicle is subsequently operated using the adjusted one or more parameters.

A side mirror assembly of a vehicle is provided herein. The side mirror assembly includes a body portion and a camera mounted to the body portion for capturing images of a rear and a side-vehicle operating environment. The camera includes a horizontal field of view angle defined by a first horizontal extent intersecting a centerline longitudinal axis of the vehicle and a second horizontal extent making an angle with a lateral axis of the vehicle that intersects the camera.

A computer system is provided. The computer system comprises a processor device configured to receive map data representing characteristics of a road ahead of a vehicle, the vehicle having an actual vehicle width and an actual vehicle length; determine a maximum width of the vehicle based on at least the actual vehicle width and the map data; and provide visual information representing the maximum width to a driver of the vehicle.

A system and method for mitigating collisions for an articulated work vehicle is disclosed. The system includes a controller configured to determine a safe-zone around the articulated work vehicle based on signals corresponding to sensed objects around the articulated work vehicle. The controller is further configured to determine a position and velocity of one or more peripheral points on the articulated work vehicle based on signals from a set of sensor systems operatively coupled to the articulated work vehicle. The controller is further configured to receive a driver control input. The controller is further configured to apply a limit to the driver control input when a peripheral point on the articulated work vehicle is expected to be within a predetermined distance to a nearest edge of the safe-zone.

An arrangement for improving maneuverability of a vehicle combination that includes a first vehicle unit, a second vehicle unit and a third vehicle unit interconnected by articulated joints, where the vehicle combination includes two driven axles and where each driven axle can be controlled independently, an arrangement for determining the articulation angel between the vehicle units, an arrangement for determining a steering wheel angle of the vehicle combination, an arrangement for determining the speed of the vehicle combination, an arrangement for determining the yaw rate of the vehicle units, and an arrangement for determining a delay value between the steering wheels of the vehicle combination and at least one articulated joint, where the arrangement is adapted to control a desired articulation angle of the articulated joints by coordinating the force ratio between the two driven axles by using the determined yaw rate of the vehicle units and the determined delay value.

A hitch assist system and method are provided herein. A detection system determines a vehicle heading and a trailer heading. A controller is coupled to the detection system for generating a path along which the vehicle is autonomously maneuvered toward a trailer. The path ends at a final position in which the vehicle and trailer headings are related by a specified angle therebetween.
