A device and method operated thereby may control 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 device, and method operated thereby, may sense, at intervals as the fifth wheel rises, a pressure value of the hydraulic fluid in the chamber. The device, and method operated thereby, may process the pressure values to determine when the landing gear is lifted off the ground.

In an engine room, heat insulators are provided on the rear side in the forth and back direction of a vehicle with respect to an engine and on the front side in the forth and back direction of the vehicle with respect to a dash panel arranged on a back side of the vehicle with respect to the engine. A top flange portion is formed at a top of a first heat insulator. The top flange portion is extending in a direction obliquely upward and backward of the vehicle to guide air heated by an exhaust system from the engine in an upward direction of the vehicle. A top bent portion is formed at a top of a second heat insulator such that the top bent portion is arranged in the vicinity of the cowling panel in order to guide the heated air in an upward direction of the vehicle.

A container transportation system using autonomous driving includes: a container to be transported; an autonomous vehicle docked with or undocked from the container and autonomously travelling to transport the container to a transport destination; and a management server controlling travelling of the autonomous vehicle, wherein the autonomous vehicle comprises a container coupling part coupled to the container, and the container comprises: a container body; a plurality of height adjustment pillars coupled to respective corners of a lower surface of the container body and adjustable in length to lift or lower the container body from or to the ground; and a vehicle coupling part formed on the lower surface of the container body and coupled to the container coupling part.

A control system includes one or more processing circuits comprising one or more memory devices coupled to one or more processors. The one or more memory devices are configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to acquire speed data regarding current speeds of tractive elements of the vehicle from tractive element speed sensors of the vehicle, determine speed references for the tractive elements to perform autonomous driving operations where the speed references indicate speeds at which each of the tractive elements should rotate to accommodate the autonomous driving operations, and control at least one of a driveline or a brake system of the vehicle to selectively alter the current speeds of the tractive elements of the vehicle based on the current speeds and the speed references to accommodate the autonomous driving operations.

A work vehicle according to the present invention includes: a recessed portion (4) that is provided in a lateral side surface (31a) of an engine hood (30) and is recessed from the lateral side surface (31a) toward the inside of the engine hood (30). The recessed portion (4) includes a recessed portion bottom surface (41) that is recessed inward from the lateral side surface (31a) of the engine hood (30), and a peripheral wall portion (42) that is continuous with a peripheral edge of the recessed portion bottom surface (41) and a peripheral edge of a recessed portion inlet opening (40) that is formed in the lateral side surface (31a). A work light (5) that emits light forward and downward is provided on the peripheral wall portion (42).
