A semitrailer rear lighting device for enhancing safety of a semitrailer hauling an oversized load includes a plurality of brackets, a pair of bars, and an indicator. Each bracket is mountable to a respective opposed side of a semitrailer so that at least two brackets are mounted to each opposed side. Each bar is slidably engaged to the brackets positioned on a respective opposed side of the semitrailer. The bars are selectively extensible from a rear of the semitrailer to position a terminus of the pair of bars past an end of an oversized load that extends past the rear of the semitrailer. The indicator is engaged to the terminus of the pair of bars. The indicator indicates to a trailing motorist one or more of the rear of the semitrailer, the end of the oversized load, a braking action of the semitrailer, or a turning of the semitrailer.

A transportation refrigeration system (100, 200, 300) includes a refrigeration system component (110), a linear generator (104, 202, 310) electrically connected to the refrigeration system component (110), and a linkage (142, 214). The linkage (142, 214) is operably connected to the linear generator (104, 202, 310) to convert movement of the transportation refrigeration system (100, 200, 300) into electrical power for communication to the refrigeration system component (110). An electric transportation refrigeration system used to cool a trailer box are also described.

A transport refrigeration system includes a transportation refrigeration unit; an energy storage device configured to provide electrical power to the transportation refrigeration unit; and an electric generation device 340 operably connected through a mechanical interface 370 to at least one of a wheel 364 of the transport refrigeration system and a wheel axle 365 of the transport refrigeration system; the mechanical interface includes: a first clutch mechanism 371 operable to selectively engage the electric generation device with at least one of the wheel and the wheel axle to generate electrical power to charge the energy storage device; and a second clutch mechanism 372, the second clutch mechanism is an overrunning clutch configured to disengage the electric generation device from the wheel and/or the wheel axle when a rotational velocity of the electric generation device is greater than a rotational velocity of the wheel and/or the wheel axle.

An integrated housing assembly can be mounted on a roof of a vehicle, such as a semi-trailer truck. The integrated housing assembly includes a main enclosure that includes four sides, a top panel, and a bottom panel. One of the four sides is a front panel that is inclined towards the ground. The main enclosure includes one or more cavities. A front panel of the integrated housing assembly includes one or more openings to allow cameras or sensors to be placed within the one or more cavities and behind the one or more opening. The cameras or sensors cameras can be clamped at a downward angle within multiple lock apparatus. The angled front panel and the inclined cameras or sensors within the lock apparatus allow the cameras or sensors to obtain images or sensor data from one or more regions of interest at some distance from the front of the vehicle.

Systems and method of forming a structure from a trailer body are disclosed herein. An example structure can be formed from a portion/section of a trailer, such as a semi-truck, or dry-van, trailer. The trailer has a unibody construction allowing the section(s) cut/formed therefrom to be self-supporting. The self-supporting sections can be enclosed on one or more open ends, i.e. the ends formed by cutting or sectioning the trailer, to enclose the section. The enclosed section can then be outfitted/equipped, as needed, to form the complete structure.

Systems, methods, and a device which produces and stores electrical energy from primarily the forward movement of a vehicle is disclosed. This device has a variety of potential applications, such as use with a semitrailer and various types of electric vehicles. It also includes a number of features, such as functioning as a cryptocurrency mining rig that uses excess electricity generated, that add to its usefulness.

A cargo body panel includes an interior side, an exterior side, a primary recess, a secondary recess positioned within the primary recess, and a logistics track. The interior side defines an interior plane. The exterior side defines an exterior plane. The primary recess includes a primary recess interior side defining a primary recess interior plane and a primary recess exterior side defining a primary recess exterior plane. The primary recess interior plane is recessed from the interior plane in a direction toward the exterior plane. The secondary recess includes a secondary recess interior side defining a secondary recess interior plane and a secondary recess exterior side defining a secondary recess exterior plane. A distance between the secondary recess interior plane and the interior plane is greater than a distance between the primary recess interior plane and the interior plane. The secondary recess exterior plane is non-coplanar with the exterior plane.

In one aspect of the present disclosure, a method is provided for operating a vehicle system comprising a motor, a battery, and a controller. The vehicle system is configured to provide at least one of regenerative braking wherein the motor operates to charge the battery and propulsion wherein the motor uses electrical power from the battery to propel the vehicle. The method includes, at the controller, determining an effective motor power at a motor speed and a motor torque. The effective motor power is determined based at least in part on a calculated motor power and an electrical power loss of the motor corresponding to the motor speed and the motor torque. The method further includes causing the motor to apply the motor torque to a wheel of the vehicle upon the effective motor power satisfying an operating condition of the vehicle system.

Clamp devices can be operated remotely to facilitate the installation, removal and other handling of wheels and tires for large vehicles. The clamp devices generally include an attachment mechanism, a gripping mechanism, an actuating link operable to move the gripping mechanism between an open and closed position, an actuator to activate the actuating link, a transmitter for sending command signals to the clamp devices for the purpose of opening or closing the gripping mechanism and a receiver for receiving such command signals.

For a vehicle (1) with a tractor (2) and a trailer (3), a view system has a capture unit (10) with an image sensor (12) for capturing image data of an area of view, around the vehicle, a processing unit (20) for processing the image data, and a reproduction unit (30) for reproducing at least one first image section (410) and one second image section (420) of the area of view (40) captured by the capture unit (10). The processing unit provides different resolutions of image data depending on the position of the tractor with respect to the trailer.
