A door hinge device for a vehicle is capable of facilitating two doors to be simultaneously or independently opened or closed in a state in which rotation trajectories of the doors are ensured as a hinge bar connected to a carrier of a speed reduction unit through a hinge shaft and a rack and a pinion connected to a rotation shaft of a sun gear set a rotation amount of the doors during a process in which a hinge unit of the door moves along a rail in a diagonal direction toward the outside of a vehicle body in a vehicle including no B pillar.

An embodiment structure includes a housing configured to be mounted on a door of a vehicle, a casing configured to be movable in the housing, a striker mounted at one side of the casing and configured to be fixed by being caught by a latch part or released, a casing guide unit connected to the casing and configured to guide a forward movement of the casing, an elastic force providing unit configured to apply elastic force in a rearward direction of the casing, and an operating unit configured to move the casing guide unit forward or rearward.

A door connection structure includes a door guide for guiding a door in the longitudinal direction of a vehicle body, a door hinge arm mounted on the vehicle body, and including a hinge rotation shaft and a door rotation shaft, the door hinge arm rotating around the hinge rotation shaft when the door is sliding, a door hinge rotatably mounted around the door rotation shaft and connected to the door, a first catcher rotatably mounted on the door hinge arm and of which a center striker guide is formed thereto, and a center striker which is inserted into the center striker guide to rotate the first catcher and limits rotation of the first catcher when the door swings so that the door swings around the door rotation shaft.

A door system is provided for a motor vehicle. That door system includes (a) a first independently operable first, door, (b) an independently operable second door, (c) an articulating door interface carried on the first door and (d) a guide on the motor vehicle body. The guide displaces the articulating door interface between a door sealing position when the first door is closed and a door opening position when the first door is opened. A related method is also provided.

Techniques for controlling a vehicle based on a collision avoidance algorithm are discussed herein. The vehicle receives sensor data and can determine that the sensor data represents an object in an environment through which the vehicle is travelling. A computing device associated with the vehicle determines a collision probability between the vehicle and the object at predicted locations of the vehicle and object at a first time. Updated locations of the vehicle and object can be determined, and a second collision probability can be determined. The vehicle is controlled based at least in part on the collision probabilities.

A latch assembly for a closure system having first and second closure members each movable between open and closed positions and method of operation are provided. The assembly includes a primary latch mechanism that has a primary actuation group to control actuation of the first closure member. The latch assembly also includes a secondary latch mechanism that has a secondary actuation group operable to control actuation of the second closure member. A controller unit is coupled to the primary and secondary actuation groups and determines which of the primary actuation group and the secondary actuation group to actuate and controls actuation of at least one of the primary actuation group and the secondary actuation group accordingly. The primary and secondary latch mechanisms, primary and secondary actuation groups, and controller unit are all integrated into the housing.

A system for adjusting a size of an access into a vehicle is provided. The system may include a pillar, which may be substantially vertical, and a track allowing the pillar to be moved. A latch may be attached to the pillar securing the pillar along the track. The pillar may be secured at one or multiple locations along the track. Multiple rolling mechanisms may be part of the pillar. These mechanisms may allow the pillar to glide back and forth enlarging or reducing the entrance into the vehicle from the front or rear entrances. The track may be interior to a front and rear door of the vehicle.

A system for preventing sliding vehicle doors from opening during collisions is disclosed. The system includes at least one roller assembly of a sliding door connected to a guiderail on a vehicle body. The roller assembly includes a protruding member that interfaces with a protrusion engaging member attached to the vehicle body. During normal operation, the protruding member clears the protrusion engaging member. During a collision in which the sliding door is pushed laterally outwards, the protruding member contacts the protrusion engaging member and stops the outward motion of the sliding door. In some cases, a vehicle includes corresponding protruding members and protrusion engaging members for both an upper roller assembly and a lower roller assembly of a sliding door.

A door hinge device for a vehicle is capable of facilitating two doors to be simultaneously or independently opened or closed in a state in which rotation trajectories of the doors are ensured as a hinge bar connected to a carrier of a speed reduction unit through a hinge shaft and a rack and a pinion connected to a rotation shaft of a sun gear set a rotation amount of the doors during a process in which a hinge unit of the door moves along a rail in a diagonal direction toward the outside of a vehicle body in a vehicle including no B pillar.

Disclosed embodiments may include a vehicle without a B-pillar that has barn doors and partially frameless windows. The barn doors may include a window seal system having a primary seal for creating a watertight barrier when the window is in a first closed position. Upon the vehicle exceeding a predetermined speed threshold, the vehicle may automatically raise the window from the first closed position to being in a second closed position in which a secondary seal secures the window to prevent buffeting of the window. Disclosed embodiments may further include a seal and door structure that provides a pair of seals (an inner seal and an outer seal) between the front and rear barn doors that provide a watertight barrier when the doors are closed together and that also allows for each of the front and rear doors to be independently opened and closed in a barn-door fashion.
