A gooseneck trailer having a coupler attached to its neck. The coupler having a recess at its lower end, wherein the diameter of the recess is slightly larger than a diameter of the hitch ball, thus permitting the coupler to receive the hitch ball. The gooseneck trailer further comprises a guide attached to the lower end of the coupler over an exposed area around the recess. The guide having a round arch portion and a pair of prongs. The round arch having a crown portion and a pair of haunches. The radius of the curvature of the crown of the round arch is proportional to the radius of the hitch ball. The pair of prongs are continuous with the pair of haunches, wherein the crown portion, the two haunches, and the two prongs are integral.

A safety apparatus for a fifth wheel coupling having locking jaws arranged to detachably couple to a trailer having spring applied air brakes, the fifth wheel coupling comprising a locking component that is moveable between a first position whereat the locking jaws are in a coupled state and a second position whereat the locking jaws are in a decoupled state, the safety apparatus comprising a pneumatic valve arrangement pneumatically coupled to both a constant air pressure supply and an air park brake supply that supplies pressurised air to the spring applied air brakes, and a mechanical actuator mechanically coupled to the locking component and configured to mechanically actuate the pneumatic valve arrangement when the locking component moves from the first position to the second position, thereby causing the pneumatic valve arrangement to block flow in an air park brake supply line for preventing the spring applied air brakes from releasing.

A trailer device for an agricultural vehicle includes a frame part and a guide part longitudinally, displaceably mounted in the frame part. The guide part includes a coupling element provided on an end face. The frame part is pivoted by a lifting apparatus for raising and lowering the coupling element relative to a base frame for attaching to a load-bearing vehicle structure. The device includes at least one spring element arranged between the base frame and the frame part such that the spring element exerts a pretensioning force on the frame part for assisting the raising of the coupling element.

An industrial truck (21) with a jaw coupling (1) that includes a coupling body (22) and a coupling pin (4), a system including such an industrial truck and a trailer (40), and a method for coupling the trailer to the industrial truck. The industrial truck includes a control unit (28), at least one locking sensor (17) and a locking actuator (8). The locking sensor is configured to recognize whether a coupling eye (26) of a drawbar (18) of a trailer is located in a locking position within the coupling body. The control unit is configured to receive and evaluate signals from the locking sensor and, when the locking sensor recognizes that the coupling eye is located in or near the locking position, the control unit is configured to control the locking actuator so that it actuates the coupling pin such that the coupling pin is shoved through the coupling eye.

A trailer coupler assembly facilitates the automatic coupling and decoupling of a trailer. A trailer coupler assembly can include a main body with a frontward-facing opening for receiving a rearwardly oriented trailer ball. A locking assembly can be integrated with the main body and can allow the rearwardly oriented trailer ball to insert into the frontward-facing opening to automatically secure a trailer to a vehicle. A release assembly can interface with the locking assembly to enable the rearwardly oriented trailer ball to be decoupled from the main body.

A device to align a trailer coupler to a hitch ball intended for use with a standard ball mount hitch. The device has a base and a plurality of vertical surfaces which are orthogonal to the base. The device mates with a standard hitch ball. The base has a through hole that can accommodate the shank of a standard hitch ball. The shank of the hitch ball is inserted through the base and through a ball mount platform. A threaded fastener secures the hitch ball. When a trailer coupler contacts the device, the device center the trailer coupler over the hitch ball.

An adjustable capture plate for a fifth wheel hitch is disclosed. An example capture plate includes a skid plate couplable to a fifth wheel hitch, and a clamping system including, a base coupled to the skid plate, a pressure plate slidably coupled to the base, and a crank arm coupled to the pressure plate via a link, wherein rotation of the crank arm about an anchor pin of the base corresponds to linear travel of the pressure plate along the base, the pressure plate movable between a first position in which the pressure plate engages a pin box of a trailer and a second position in which the pressure plate is positioned away from the pin box.

A hitch configured to selectively latch to a tow bar is provided. The hitch includes a housing, a frame defining a receiving cavity, a moveable arm, an actuator configured to move the arm between an unlatched position and a latched position, and a contact sensor mounted within the housing on a slotted mounting plate. The arm is configured to engage the tow bar when in the latched position. The slotted mounting plate is configured to enable a position of the contact sensor to be adjusted based on a geometry of the tow bar. The actuator is activated by the contact sensor sensing the presence of the tow bar within the receiving cavity.

Provided is a vehicle control system, a vehicle control method, and an image sensor, the vehicle control system including: an image sensor disposed on the vehicle to have a field of view of an outside of the vehicle to capture image data; at least one non-image sensor disposed on the vehicle to have a field of sensing of the outside of the vehicle to capture sensing data; at least one processor configured to process the image data captured by the image sensor and the sensing data captured by the non-image sensor; and a controller configured to determine a chance of a collision with an obstacle with respect to a rear side warning determination reference area that is changed depending on whether a trailer is mounted on the vehicle, on the basis of at least part of processing at least one of the image data and the sensing data.
