In a vehicle body front structure, an operating unit that extends upward to raise a front hood by a predetermined amount when a vehicle collides against an obstacle in front is arranged in a dashboard upper configured to introduce outside air into an interior. The operating unit is mounted in a vehicle body so as to be displaced downward by an external force acting from above after extending upward. An opening portion for drain is provided in a bottom portion of the dashboard upper. The opening portion is arranged at a position where the operating unit can be moved downward by the external force acting from above after extending upward.

Removable devices and systems for operating the four wheel drive (4WD) system of a tow vehicle having an electronically controllable part time 4WD system including a selectable 4WD low range mode are described. The removable device may comprise a first interface for coupling the removable device to a selector, the selector providing an indication of a desired operating mode for the 4WD system; a second interface for coupling the removable device to a controller-area network bus of the tow vehicle; a memory storing vehicle control codes; and at least one controller communicatively coupled to both the first interface and the second interface. The removable device, and system, may allow a vehicle operator to operate the tow vehicle in two-wheel drive low range mode.

A suspension automobile comprising an automobile body, wheels and a flow disturbing plate, the wheels connect the flow disturbing plate through connecting devices, and a fluid channel communicating with the outside is formed between the upper surface of the flow disturbing plate and a bottom shell of the automobile body; a power device used for driving the automobile is contained in the body and is suspended along with lift force generated by the body. The invention changes the common sense that the wheels bear all weight generated by the self-weight, loads, and gravitational acceleration of the automobiles when traveling; the body which exceeds 90% by weight of the automobile generates lift force to suspend, the wheels eliminate lift force; meanwhile, a novel propelling force source is found from fluid resistance; the suspension automobile can be driven by various energy including engines and clean energy, thus effectively reduce energy loss.

Disclosed herein is an expandable habitation unit. The unit includes a main frame and a main floor with an exposed habitation area. A rear module with a floor located over a rear portion of the main floor. The rear module floor is connected to the main frame to allow limited movement over the rear portion of the main floor. A side module with a floor is located over a first side portion of the main floor. The first side module floor is connected to the main frame to allow limited movement over the first side portion of the main floor. Another side module has a floor located over a second side portion of the main floor. The second side module floor is connected to the main frame to allow limited movement over the second side portion of the main floor. The modules are moveable along their limited paths of travel to vary the size of the exposed habitation area.

A tarp distributing apparatus includes a tarp guide device held in an immobile condition adjacent to and extending upright to above a rear location on a truck load bed so as to establish the height to which a tarp can be moved to above and over the rear of a cargo on the truck load bed, a tarp draught device mounted in a mobile condition adjacent to and extending upright to above the truck load bed forwardly of the tarp guide device so as to undergo movement relative thereto and along the truck load bed for engaging and pulling the tarp relative to the tarp guide device forwardly over the cargo, and an actuation mechanism configured to manipulate and move the tarp draught device relative to the tarp guide device and the cargo so as to accomplish distributing the tarp over at least a portion of the cargo.

An expandable habitation unit includes a main frame and a main floor with a habitation area. A rear module with a floor is located over a rear portion of the floor. The rear module floor is connected to the main frame to allow limited movement over part of the main floor. A side module has a floor located over one side of the main floor. The first side module floor is connected to the frame to allow limited movement over one side of the main floor. Another side module has a floor located over a second side of the main floor. The second side module floor is connected to the main frame to allow limited movement over the second side portion of the main floor. The modules can move along their limited paths of travel to vary the size of the habitation area.

A method and a system for controlling cooling of a vehicle, and a vehicle are provided in the present disclosure. In the present disclosure, a maximum value among cooling demand values of cooling objects is used to control a servo component in a cooling system to operate according to an execution opening determined by a preset corresponding relation, so that operating states of the servo components may be correlated and may be comprehensively controlled, so as to prevent the control system from oscillating and improve control stability, thus solving a problem that periodic oscillation of the operating states of the servo components is easily caused and service life of the servo components is affected in existing control modes of the cooling system of the vehicle.
