A method for damping a movement of a door system of a vehicle that is equipped with a damping system having an adjustable and controllable damping action. A movement of the door system between a closed position and an open position is damped in a controlled manner. A measurement of the change in speed of the speed of movement of the door system is calculated and if the change in speed exceeds a predefined limit value, a set, gentle damping action is changed over to a greater damping action.

An adjustable stopper device (1) for a vehicle door or hood, includes a base part (100), and adjustment part (200), a stopper part (300) and a fastening structure (400). The adjustment part is connected to the base part via threads (120, 220) and thereby rotatable around a device axis (210) with respect to the base part (100). The stopper part is configured to contact the vehicle door and to provide an abutment surface (310) for the vehicle door when the vehicle door is closed, wherein the stopper part is connected to the adjustment part and wherein the axial position of the abutment surface is adjustable by turning the adjustment part with respect to the base part around the device axis. The fastening structure fastens the base part to the car body (2). A vehicle with, use of and method for manufacturing such a device are also described.

Provided is a motorized drive system for actuating a door, including at least one gear having a spindle axis and a drive axis, wherein the gear assembly is designed to convert a rotational movement about the drive axis into a rotational movement about the spindle axis; at least one spindle assembly having a threaded spindle which can be rotated about a spindle axis, wherein the threaded spindle is mechanically coupled to a part of the gear assembly that can be rotated about the spindle axis, and at least one drive assembly for driving the threaded spindle with a drive shaft, wherein the drive shaft is mechanically coupled to a part of the gear assembly that can be rotated about the drive axis.

A method of installing a vehicle component to a vehicle panel is provided. The method includes aligning a rib receiving channel of the vehicle component with an alignment rib that is formed integrally with the vehicle panel while also aligning a fastening opening of the vehicle component with a fastening opening through the vehicle panel. The alignment rib is inserted into the rib receiving channel. A fastener is inserted through the fastening openings of the vehicle component and the vehicle panel. The fastener is tightened while the alignment rib and rib receiving channel inhibit rotation of the vehicle component.

A method of installing a vehicle component to a vehicle panel is provided. The method includes aligning a fastening opening of the vehicle component with a fastening opening through the vehicle panel. The vehicle component abuts against an alignment rib that is formed integrally with the vehicle panel. A fastener is inserted through the fastening openings of the vehicle component and the vehicle panel. The fastener is tightened while the alignment rib inhibits rotation of the vehicle component.

The invention controls a power cinching function of a motor vehicle door latch in order to improve door seal performance under conditions wherein vibrations could otherwise reduce seal effectiveness. With the door latched closed in a flush condition, the vehicle speed is compared to a slow-speed threshold. When the vehicle speed is greater than the slow-speed threshold, then a vehicle vibration parameter is compared to a vibration threshold. When the vibration parameter is greater than the vibration threshold, then the power cinching function is activated to move the door to to a subflush condition which increases a compression of the seal between the door and a vehicle door frame. When the door is in the subflush condition, the vehicle speed continues to be compared to the slow-speed threshold, and when the vehicle speed is less than the slow-speed threshold then the door is released back to the flush condition.

A door component has a damper device with two connection units that can be moved relative to each other for damping a door movement of a door of a vehicle. The damper device contains a magnetorheological fluid, as an operating fluid, and a cylinder unit having a first chamber and a second chamber. The two chambers are separated from each other by a piston which is provided with a damping valve. The damper device has a connection which is constructed for coupling to a drive. The damper device can be moved in an active manner at least from a first position into a second position by the drive which is coupled via the connection.

A vehicle door control system is provided, and includes a body hinge member connected to the vehicle body, a door hinge member connected to the door, a brake and a control system. The brake includes a plate pack that includes a plurality of body brake plates connected to the body hinge member, and interleaved with a plurality of door brake plates connected to the door hinge member. The plate pack is positionable in a braking state in which the body brake plates and the door brake plates are frictionally engaged with one another to provide a first resistance to relative rotation therebetween so as to hold the vehicle door in a selected position, and a release state in which the body brake plates and the door brake plates provide a second resistance to relative rotation therebetween that is less than the first resistance.

A device and method for automatically closing a tailgate of a motor vehicle having a body and a tailgate closing device, is described. The tailgate closing device comprises first and second closing elements. A suspension strut is situated on a first side of the tailgate and a power strut is situated on a second side of the tailgate opposite the first side. The suspension strut and the power strut are both connected to the tailgate and to the body. The first closing element is situated on the tailgate and the second closing element is situated on the body. The first and second closing elements are designed to engage into each other during the closing of the tailgate to effectuate the closure of the tailgate. The torque acting via the power strut onto the tailgate is reduced during the closing of the tailgate when the distance between the first and second closing elements is less than a threshold value.
