A trailer truck is the combination of a truck and one or more trailers used to haul freight. A trailer attaches to the truck via a trailer coupling (hitch), with much of its weight borne by the truck. The result is that both the truck and the trailer will have a distinctly different design than a rigid truck and trailer. Exemplary vehicles are provided, such as heavy duty trucks having truck bodies with improved aerodynamic characteristics, including improved drag coefficients.

A passage gate for allowing or preventing people to enter or to exit a passage area comprising a base portion (110) and a panel portion (120) is provided. The passage gate (100) is configured to be driven in a first operation mode and a second operation mode. When the passage gate (100) is driven in the first operation mode the panel portion (120) is slidable relative the base portion (110) between a first open position, allowing people to pass, and a closed position preventing people from passing through the passage gate (100). When the passage gate (100) is driven in the second operation mode the base portion (110) is rotatable between the closed position and a second open position for achieving a larger passage area.

A milking arrangement includes plural milking places, each milking place having a primary end and an opposite secondary end, an entrance at the primary end, a front side and a rear side, which both extend in parallel with the longitudinal axis, a plurality of sequence gates arranged between the front side and the rear side, each of the sequence gates being pivotable between a closed position and an open position, each sequence gate being only pivotable from its closed position to its open position in a pivotation direction in which the front end is pivoted into a milking place towards the front side of the milking arrangement, main extension planes of the sequence gates being aligned when the sequence gates are in their closed position, with a lower edge of each sequence gate defining a bulge that extends downwards.

Systems and methods are provided for protecting a door system from damage by a back electromotive force (EMF) voltage generated when a door coupled to a door actuator is manually closed. The door system may include a driver configured to drive the door actuator to move the door, and a back EMF protection circuit. The back EMF protection circuit detects a back EMF voltage generated by the door actuator when the door is moved, and determines whether the back EMF voltage exceeds an overvoltage threshold. In response to determining that the back EMF voltage exceeds the overvoltage threshold, the back EMF protection circuit causes the driver to transition to an enabled state to short the back EMF voltage to ground.

A vehicle control device includes: an acquisition section configured to acquire a determination result as to whether a predetermined communication terminal is in a vehicle cabin interior area, and acquire another determination result as to whether or not the communication terminal is in a vehicle cabin exterior area; and a control section configured to, based on the determination results of the acquisition section, initiate a closing operation of a vehicle door in cases in which a determination is made that the communication terminal is in the vehicle cabin exterior area, and stop the closing operation in cases in which a determination is made that the communication terminal is in the vehicle cabin interior area after the closing operation was initiated.

An opening/closing body control device continues an as-needed operation where the opening/closing body is controlled in response to the operation instruction signal even when an abnormality in an opening/closing position of the opening/closing body is detected, continues opening and closing the opening/closing body until it is determined that the abnormal state in the opening/closing instruction signal is confirmed even when an abnormality in the opening/closing instruction signal is detected during the as-needed opening/closing operation, and stops opening and closing the opening/closing body the abnormal state in the opening/closing instruction signal is confirmed. The confirmation time at the presence of the opening/closing position abnormality is shorter than that at the absence of opening/closing position abnormality.
