Pivoting snow-clearing trailer (1) intended to be towed by a towing vehicle (3) with a towing hitch (4), comprising: a chassis (5) extending longitudinally in a chassis direction (I-I) between a chassis anterior end (5a) and a chassis posterior end (5b), and developing transversely between a chassis first side (5c) and a chassis second side (5d) which are opposite one another, a snow-clearing blade (6) borne along the chassis first side (5c).

Detection means (10) are able to generate a presence signal when the snow-clearing trailer (1) is pivoted and when an object or an individual is stationed in an area (A1) to the side and/or an area (A2) to the rear of the chassis second side (5d).

Snow-clearing trailer (1) having a chassis (5) extending longitudinally in a chassis direction (I-I) and having a drawbar (9). Pivoting means (11) allow the selective pivoting movement of the chassis (5) and the drawbar (9) with respect to one another. A drawbar locking bar (12) of fixed length can be attached to the drawbar (9) and to the chassis (5) so as to immobilize the drawbar (9) on the chassis (5) in a transport position.

Detection means (13) generate an attachment signal when the drawbar locking bar (12) is attached to the drawbar (9) and to the chassis (5). The detection means (13) and disabling means are arranged in such a way that when the detection means (13) generate an attachment signal, the disabling means prevent any actuation of the pivoting means (11).

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 system according to the present disclosure includes an actuator control module and a damping ratio module. The actuator control module is configured to control an actuator of a vehicle to cause the vehicle to perform a yaw maneuver by rotating about its yaw axis. The damping ratio module is configured to determine a damping ratio based on an operating parameter measured during the yaw maneuver. The operating parameter includes at least one of a yaw rate of the vehicle, a yaw rate of a trailer connected to the vehicle, a lateral acceleration of the vehicle, a lateral acceleration of the trailer, a heading angle of the vehicle, and a hitch angle between a longitudinal axis of the vehicle and a longitudinal axis of the trailer.

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 heavy-duty vehicle, comprising a steering unit mounted on a vehicle frame of the heavy-duty vehicle, wherein the steering unit is rotatable about an axis of rotation of the steering unit. The heavy-duty vehicle comprises a steering input element connected to the steering unit and configured to cause the steering unit to rotate about the axis of rotation of the steering unit. The steering unit has at least one connecting portion configured to be connected to one or more of a steering device of the heavy-duty vehicle or the steering input element of the heavy-duty vehicle. The steering unit comprises at least one actuating unit configured to change a distance of at least one connecting portion relative to the axis of rotation of the steering unit.

Methods and apparatus to control a vehicle trailer using torque vectoring are disclosed. An example apparatus to control a trailer of a vehicle includes condition determination circuitry to determine, based on data from sensors on at least one of the trailer or the vehicle, whether a condition associated with the vehicle is satisfied, and torque control circuitry to adjust, in response to the condition being satisfied, a first torque of a first motor and a second torque of a second motor, the first motor operatively coupled to a first wheel of the trailer, the second motor operatively coupled to a second wheel of the trailer.
