In a control system for steering a combination with at least one electronic control unit, with a sensor apparatus for capturing the bend angle of the combination and with a display unit, the control unit has a memory region for storing a maximum reversible bend angle, a memory region for storing an upper bend angle change threshold value, and/or a memory region for storing a left hand bend angle range and a right hand bend angle range with reference to the zero line corresponding to a straight combination. A functional unit is designed to output a recommended action for moving forward on the display unit and/or for carrying out an autonomously executed forward movement, when the presence of at least one defined situation in relation to the values related to the bend angle stored in the memory region is ascertained through evaluation of the sensor apparatus.

A steerable cart or trailer is towed by another vehicle. A reverse linkage made up of arms that crisscross one another extends between the tow vehicle and the steerable trailer. The linkage arms are parallel a distance from the tow vehicle before crisscrossing with one another towards the trailer. The linkage arms are rotatable at each end. This allows the arms to rotate in a manner in which the trailer will more closely follow the path of the tow vehicle, especially when the tow vehicle is in the process of turning. The trailer will follow in a manner that reduces compaction and provides a simpler overall operation of equipment.

A yaw angle measuring device for a separable coupling for fifth wheel couplings includes a sensor element and a measuring arrangement, wherein the sensor element is configured to be arranged on a first coupling partner and the measuring arrangement is configured to be arranged on a second coupling partner, wherein the first coupling partner is configured to be mounted by the coupling arrangement such that the first coupling partner is rotatable about an axis of rotation relative to the second coupling partner, wherein the sensor element generates a measuring signal in the measuring arrangement which serves to determine the yaw angle about the axis of rotation.

An all-wheel steer trailer having six wheels is disclosed. The trailer includes an elongated frame means having first and second frame members having forward and rearward ends. A pivotal axle support is positioned at the forward end of the trailer and has first and second wheels rotatably mounted thereto. An elongated tongue has its rearward end secured to the axle support for pivotally moving the axle support and the first and second wheels mounted thereon. A tandem axle assembly is mounted on the first and second frame members forwardly of the rearward ends thereof. The tandem axle assembly includes third, fourth, fifth and sixth wheels which are rotatably and pivotally secured to the frame means. When the first and second wheels are pivotally moved in one direction, the third, fourth, fifth and sixth wheels are pivoted in an opposite direction.

A terminal tractor includes four independently steerable wheels, each with their own dedicated drive motor and each with their own dedicated steering device. The terminal tractor includes a controller operable to provide input commands to the drive motors and to the steering devices to operate the terminal tractor. The terminal tractor also includes a fifth wheel coupling which includes a lifting mechanism capable of raising and lowering the fifth wheel coupling a in single vertical direction.

A trailer assembly with improved lateral support structure and steering system control of the axial wheels on a front elongated trailer and a rear elongated trailer to remain in a collinear following configuration to carry elongated loads extending over the extended lengths of the combination of the front elongated trailer and the rear elongated trailer and allow ready turning control.

A trailer including a hydraulic steering system includes: a trailer body; a plurality of axles connected to the trailer body; a steering cylinder connected to at least one axle of the plurality of axles and configured to turn the at least one axle; a sensing cylinder; a controller; and a hydraulic steering system. The hydraulic steering system includes a hydraulic circuit including a plurality of hoses and valves, and the steering cylinder is in fluid communication with at least one of the sensing cylinder and the controller. The hydraulic steering system is configured to transition between: (1) an automatic steering mode and (2) a manual steering mode. A towing system and a method of steering a trailer are also disclosed.

A towing assistance apparatus includes an image acquisition unit successively acquiring a rear image and a lateral image serving as a surrounding image captured by an imaging unit that is provided at a towing vehicle to which a towed vehicle is configured to be connected, an angle acquisition unit acquiring a connection angle between the towing vehicle and the towed vehicle, and a display processing unit switching the surrounding image displayed at a display unit from the lateral image to the rear image in a case where the connection angle becomes equal to or greater than a first angle at which a change control for decreasing the connection angle is impossible by a steering of the towing vehicle during a rearward driving thereof in a state where the lateral image is displayed and the towing vehicle to which the towed vehicle is connected is in a rearward driving available state.
