A vehicle door system for limiting an opening angle. The system includes a track connected to the door, a clamp unit connected to and movable in relation to the track, and a blocking member connected to a vehicle body structure. The track extends through the blocking member. In a first state, the clamp unit is moveable in relation to the track and, in a second state, the clamp unit is prevented from moving in relation to the track. In the first state when the door is opened the clamp unit moves along the track. When the door, in the open position, is at a predetermined angle, the clamp unit is at a locked position in relation to the track preventing further opening of the vehicle door through interaction between the clamp unit and the blocking member.

An electronic latch system for a motor vehicle includes an electronic latch (e-latch) including an e-latch controller within a door of the vehicle. A plurality of radar sensors are located within the door for performing non-contact detection of objects around the vehicle. The radar sensors include an outside-face sensor adjacent an outside face of the door to sense an object within a first sensing zone extending from the outside face. The radar sensors also include an inner sensor adjacent an inside surface of the door to sense an object within a second sensing zone extending from the inside surface. The radar sensors also include a shut-face sensor adjacent a shut face of the door to sense an object within a third sensing zone extending from the shut face. The e-latch includes a light source for projecting a warning image and an audio source for generating an audible warning.

A method for controlling the movements of a controllable door of a motor vehicle that has two or more doors with movable door wings. One door is a main door and at least one other door is a secondary door. A control device and a sensor arrangement are associated to the doors. The secondary door includes a controllable motion influencing device, wherein a motion of the door wing of the secondary door can be at least partially controlled and influenced by way of the motion influencing device between a closed position and an open position. The motion influencing device brakes or arrests a door wing of the secondary door in the closed position for a predetermined time period after the main door has been opened, and/or in dependence on an identified situation.

The door check includes a retaining bar (20) which can be connected to one of the two door assembly parts, i.e. the door (8) or the door frame (6), and a retaining housing (13) which can be connected to the other door assembly part. In order to design a door check that allows a vehicle door to be reliably and safely blocked in an automated manner, a threaded bar (50) can be accommodated in an axially movable fashion in a cavity of the retaining bar (20).

A power tailgate detection system is provided including a vehicle, a sensing system, and a control unit. The vehicle includes a bumper and a tailgate moveable between a closed position and an open position. The sensing system is disposed on an exterior surface of the tailgate and includes at least one emitter and at least one receiver. The emitter is positioned to emit radiation in a direction parallel to the exterior surface of the tailgate. The receiver is positioned to receive the radiation emitted by the emitter. The control unit is configured to control operation of the tailgate between to prohibit movement of the tailgate toward the open position when an object interferes with the radiation.

A power swing door actuator for moving a passenger swing door relative to a body portion of a motor vehicle. The power swing door actuator includes a housing rigidly fixed to the swing door, a motor mounted to the housing, a connector link having a first end pivotably coupled to the vehicle body portion and a second end pivotably coupled to a drive nut of a spindle drive mechanism. A leadscrew of the spindle drive mechanism is rotatably driven by the motor for causing relative translational movement between the drive nut and the leadscrew which, in turn, results in pivoting movement of the connector link while the vehicle door swings between open and closed positions in response to selective actuation of the motor.

An automotive door system includes a hinge supporting a door. A door check module interconnects to one of the vehicle and the door by a linkage assembly. An output shaft is connected to the linkage assembly and rotates relative to a door check module housing. The output shaft provides an output torque to check the door in a desired door position. A sensor detects rotation of the shaft and produces a signal in response thereto. A brake assembly includes a shaft member operatively connected to the output shaft. The brake assembly has a normally closed position in which the shaft member is grounded to the housing in a door check mode. The brake assembly includes an open position that corresponds to one of a door closing mode and a door opening mode. The brake assembly moves from the normally closed position to the open position in response to the signal.

The invention relates to a collision protection device for a pivotable hatch of a motor vehicle, comprising at least one sensor for detecting an obstacle in the pivoting range of the hatch, and comprising a control unit, which is designed to output, in dependence on sensor signals of the at least one sensor, control commands for stopping an opening movement of the hatch, wherein the at least one sensor is an optical visibility sensor, which is designed for capturing an optical visibility in an environment of the sensors.

A door component has a controllable damping device and contains a magnetorheological fluid. Two connection units are movable relative to one another. One of the two connection units is connected to a support structure and the other one to a pivotable door unit. The device damps a movement of the door unit between a closed position and an open position in a controlled manner by way of a control unit. The magnetorheological damping device has a piston unit and a cylinder unit surrounding the piston unit. The piston unit divides a cylinder volume into two chambers. The piston unit is equipped with a first one-way valve. The two chambers are connected together, via an external return channel equipped with at least one controllable magnetorheological damping valve, to form a one-way circuit. When the piston unit moves in and out, the magnetorheological fluid flows through the piston unit in the same flow direction.
