The present technology describes systems and methods for a mechanized gladhand and an end effector. The mechanized gladhand may have a collar capable of rotational motion while the mating surface may be in contact with a second surface without rotating. This may reduce reaction loads while maintaining the integrity of the connection. The end effector may include a drive motor, clasping tool, and/or driving installed tool that may be used to couple a tool with the gladhand or may be used in other applications. The end effector may have a compact design to allow precise control. The movement of the end effector with the gladhand may be controlled based on image processing to align the tool with another component.

A terminal tractor includes a fifth wheel coupling which is rotatable relative to a longitudinal axis of the terminal tractor such that an opening in the fifth wheel coupling may be reoriented depending on the terminal tractor's direction of approach to a semi-trailer.

A system and method for operation of an autonomous vehicle (AV) yard truck is provided. A processor facilitates autonomous movement of the AV yard truck, and connection to and disconnection from trailers. A plurality of sensors are interconnected with the processor that sense terrain/objects and assist in automatically connecting/disconnecting trailers. A server, interconnected, wirelessly with the processor, that tracks movement of the truck around and determines locations for trailer connection and disconnection. A door station unlatches/opens rear doors of the trailer when adjacent thereto, securing them in an opened position via clamps, etc. The system computes a height of the trailer, and/or if landing gear of the trailer is on the ground and interoperates with the fifth wheel to change height, and whether docking is safe, allowing a user to take manual control, and optimum charge time(s). Reversing sensors/safety, automated chocking, and intermodal container organization are also provided.

An auto-coupling system for coupling a trailer and a towing vehicle includes a base plate between a vehicle frame and a fifth wheel of the towing vehicle, an extendable arm rotatably coupled to the base plate at a first point and configured to extend in response to relative movement of the towing vehicle and the trailer, a spring fixedly coupled to the base plate at a second point and coupled to the extendable arm, the spring being configured to exert a retractive force onto the extendable arm, and an alignment assembly rotatably coupled to the extendable arm and configured to move against an outer perimeter of the trailer.

A single axle dolly vehicle unit for a heavy duty vehicle combination, the dolly vehicle unit comprising an electrical energy source arranged to power at least one electric machine configured to drive left and right wheels of the single axle, the dolly vehicle unit further comprising a drawbar and a fifth wheel connection for mating with first and second trailer units, respectively, wherein the fifth wheel connection is arranged to be adjusted in height over ground by a variable height suspension system, the dolly vehicle unit further comprising a control unit arranged to control the variable height suspension system.

An emergency trailer release device for separating a trailer from a towing truck during an emergency situation includes an actuating module and a controller, which are mountable to a fifth wheel and within a cab of the towing truck, respectively. The actuating module is operationally engaged to and can selectively open a set of locks so that a king pin engaging the trailer to the fifth wheel is released. The controller is operationally engaged to the actuating module and can be engaged an electrical circuit of the towing truck. The controller can be selectively actuated by a driver of the towing truck in an emergency situation to signal the actuating module to open the set of locks to disengage the trailer from the towing truck, for example, when the driver believes the towing truck, the trailer, or both, are in danger of rolling over.
