Devices are for compensating for the roll of a fifth-wheel coupling, such as on a prime mover towing a semi-trailer. An automated compensation system for a fifth-wheel coupling mounted on a towing vehicle unit includes a first pivoting support to support one lateral side of the fifth-wheel coupling; a second pivoting support to support an opposite lateral side of the fifth-wheel coupling; an actuator configured to cause movement of the first and second pivoting supports; a sensor to sense a parameter relevant to determining whether roll compensation is required for the vehicle; a controller configured to receive a sensor output of the sensor and to determine whether roll compensation is required based on the sensor output, the controller being further configured to issue a control signal to cause the actuator to move the first and second pivoting supports when the controller determines that roll compensation is required.

A system for assisting in aligning a vehicle for hitching with a trailer includes a first camera and a second camera and outputting image data to the rear of the vehicle and a controller identifying at least one of the trailer or a coupling feature of the trailer within the image data and assigning a trailer type to the trailer identified within the image data, the trailer type including a first trailer type and a second trailer type. The controller further causes a portion of the image data to be presented on a display within the vehicle, the portion of the image data corresponding with the first camera in response to the trailer being assigned the first trailer type and corresponding with the second camera in response to the trailer being assigned the second trailer type.

The vehicle system can include: a set of vehicle couplings (e.g., a tractor interface, a trailer interface, etc.); a chassis, a battery pack, an electric powertrain, a sensor suite, and a controller. The modular vehicle system can optionally include landing gear, a suspension, and any other suitable set of components. The vehicle system functions to structurally support and/or tow a trailer—such as a Class 8 semi-trailer—and/or to augment/supplement a tractor propulsive capability (e.g., via a diesel/combustion engine) with a supplementary electric drive axle(s).

A method detects and prevents stall of a drive motor of an autonomous electric tractor. A stall detector receives, at intervals, a motor current value from a drive circuit of the autonomous electric tractor, determines when the motor current value reaches or exceeds a first current threshold and applies brakes, inhibits a throttle controlling the drive motor, and sets a motor stall flag. A method determines a height above the ground of a landing gear of a trailer coupled with a tractor. A lift detector controls a hydraulic pump to pump a hydraulic fluid into a chamber of a piston coupled to a fifth wheel of the tractor to raise the fifth wheel. The lift detector senses, at intervals as the fifth wheel rises, a pressure value of the hydraulic fluid in the chamber and processes the pressure value to determine when the landing gear is lifted off the ground.

A trailer stand positionable by a shunt truck is disclosed. The trailer stand includes a leg assembly having a front pair of legs and a back pair of legs, the front pair of legs connected by a front cross support and the back pair of legs connected by a back cross support, a wheel assembly having a wheel assembly frame that has a first end and a second end, the first end connected to the back pair of legs, the second end retaining an axle, the axle rotatably retaining at least two wheels, a stepped assembly having a front end, a back end, a top, and a bottom, the front end connected to the front cross support, the back end connected to the back cross support, the top of the stepped assembly providing a plurality of landing areas for an end of the semi-trailer, and a lifting frame.
