The present disclosure is directed generally to automated trailer door systems for use at vehicle loading docks. At least a portion of the trailer door system can be externally driven for opening and closing trailer doors at the loading dock. The automated trailer door system can include a counterbalance shaft that moves the trailer door between a closed position and an open position; and a drive unit having a torsion member operably coupled to the counterbalance shaft; and a drive member rotatably engaged with the torsion member, the drive member having an engagement portion accessible external to the trailer door. Rotation of the drive member via the engagement portion can rotate the torsion member to move the trailer door between the closed and open positions. A door winder can be coupled to a centering body and have a motor to rotate the drive member via the engagement portion.

Provided are a folding device, a compartment cover, and an automobile, belonging to the technical field of automobile accessories. The automobile includes the compartment cover. The compartment cover includes a folding device and plates disposed on two sides of the folding device. The folding device includes a pivot profile, a connection profile, and a rolling element. The connection profile is connected to each of two sides of the pivot profile. One of the pivot profile or the connection profile is provided with an accommodation recess. The other one of the pivot profile or the connection profile is provided with an engaging portion. The engaging portion rotates in the accommodation recess. The rolling element is rotatably disposed between the inner wall of the accommodation recess and the engaging portion.

An actuating apparatus for a vehicle part contains an actuating motor for generating an actuating force under the action of which the vehicle part can be adjusted between a closed state and an open state along an actuating path. The actuating apparatus also contains a control unit which is configured to carry out an actuating method in which, according to the method, a position measure is continuously ascertained when the vehicle part is adjusted, the position measure being characteristic of the current actuating position of the vehicle part along the actuating path. Furthermore, the position measure is set to a prespecified reference value when the vehicle part is in the closed state and when a further condition is additionally met, the further condition being linked in a reproducible manner with a specific actuating position.
