A rotary valve that controls a flow rate at which working oil is supplied to and discharged from a hydraulic cylinder that causes a wing to rotate about a rotary shaft includes a rotor that rotates as the wing rotates about the rotary shaft, and a first control flow passage and a second control flow passage formed in the rotor to control the flow rate at which the working fluid is supplied to and discharged from the hydraulic cylinder, wherein the first control flow passage and the second control flow passage respectively vary a resistance exerted on a flow of the working fluid passing therethrough as the rotor rotates.

A method for operating a vehicle in at least one parking process situation involves allocating at least one predetermined vehicle-specific or parking process situation-specific function to the at least one predetermined parking process situation of the vehicle. Whether the vehicle is in the at least one predetermined parking process situation is determined and the predetermined vehicle-specific or parking process situation-specific function allocated to the at least one predetermined parking process situation is presented to a vehicle user for activation or automatically activated when the vehicle is in the at least one predetermined parking process situation.

A convertible arrangement having a displaceable top is displaceable between a covering position, in which it spans a vehicle interior, and a storage position, in which the vehicle interior is exposed at the top and the convertible top is received by a convertible top storage space. An environment sensor and/or an environment sensor accessory are/is disposed at the convertible top.

A docking system for a vehicle and a building and a control method therefor, include a plurality of vehicle doors provided to enter the vehicle, a roof connected to an upper portion of each of the vehicle doors, and configured to be vertically lifted and lowered above and below the plurality of vehicle doors, wherein when the roof is lifted, an indoor space expands upward to connect the indoor space of the vehicle to an indoor space of the building into one space, and a sealing door respectively provided inside each of the vehicle doors, when the roof is lifted, which is rotated toward each of the vehicle doors to seal each of the vehicle doors and the roof.

A system and method for providing a folding load bearing hard tonneau cover, wherein each folding section is constructed using friction stir welds for strength, stiffness and visual appeal, wherein edge extrusions may include an integral attachment track which is capable of sustaining high tie down loads, wherein a spring loaded latching system has the strength to react the moments generated by heavy loads on top of the tonneau cover, wherein installation does not require modification to the bed but instead uses a 2 bolt attachment system, and wherein the tonneau cover may carry heavy loads on top that are easy to secure, and wherein a custom carrying frame is easily attachable to the tonneau cover to enable large and heavy loads, even some that are longer than the pick-up bed, to be carried on the tonneau cover while enabling use of the pick-up bed for other cargo.

A top of a convertible vehicle, including a top linkage which can be displaced between a closed and a storage position has a linkage assembly on either side of a vertical longitudinal center plane. Each linkage assembly includes a main multi-bar assembly, which is pivotably mounted on a respective vehicle-attached main bearing, and a front roof link, which pivots relative to the main multi-bar assembly when the linkage assembly is actuated, and is covered with a headliner assembly when the top linkage is in the closed position. The headliner assemblies comprise a front headliner flap which is articulated to the respective front roof link via a link assembly and which can be pivoted between a covering and an uncovering position, in which the front headliner flap is located when the top linkage is in the storage position and in which the respective front roof link is accessible from above.

Systems and methods to detect obstruction include detecting, by a sensor, a first parameter that corresponds to a path of traversal of a tonneau cover, determining, based on a comparison between the first parameter and a second parameter, a presence of an obstacle in the path of traversal of the tonneau cover, and modifying operation of the vehicle in response to the presence of the obstacle in the path of traversal of the tonneau cover.

A locking device for a convertible vehicle is proposed, comprising a locking support, a locking hook, which can be shifted in a translational and/or rotational manner so as to be displaced between a release position and a locked position, and a driving mechanism for the locking hook, said driving mechanism comprising a driving element, which is driven by a driving motor and drives the locking hook, as well as a detection device for detecting a position of the driving element. The detection device is a sensor, which continuously detects the position of the driving element with respect to the locking support.

A method for opening and closing a retractable roof of a convertible vehicle, wherein the roof includes a first portion and a second portion, connected together. The method includes: moving the first portion relative to the second portion between a first position and a second position, such that, at the first position, the first portion is at least partly superposed on the second portion and, at the second position, the first portion lies in substantially the same plane as the second portion, rotating the first and second portions about an axis of rotation, and translating the superposed first and second portions between a first position and a second position, such that, at the first position, the first and second portions are inside a compartment in the vehicle and, at the second position, the first and second portions are outside the compartment.
