  • Patent number: 11536062
    Abstract: A vehicle door device includes: a braking control unit applying a braking force to a swing door of a vehicle by controlling an operation of a braking device; and an action position detection unit detecting an action position of the swing door. The braking control unit sets a strong opening prevention boundary on a closing direction side from a fully open position as a mechanical opening action limit of the swing door and applies a braking force to the swing door that opens on an opening direction side from the strong opening prevention boundary.

  • Patent number: 11536063
    Abstract: A door control device stops a door such that the door does not come into contact with an obstacle existing in a rotation range of the door. The door control device includes: a distance calculation unit configured to calculate a distance from the door to the obstacle; a speed calculation unit configured to calculate an actual speed of the door; a braking force setting unit configured to set a braking condition indicating transition of a braking force applied to the door; a speed estimation unit configured to estimate transition of an estimated speed of the door from start of braking until the door stops; and a braking force correction unit configured, during braking, to correct a braking force such that the braking force is increased, or reduced, when a time gradient of the actual speed is gentler than, or steeper than, that of the estimated speed.

  • Patent number: 11473353
    Abstract: A vehicle door apparatus includes: a moving object detector configured to detect a moving object approaching a door of a vehicle; a door opening operation detector configured to detect a door opening operation performed by an occupant in the vehicle; a door opening restriction unit configured to restrict opening of the door by the door opening operation when detecting approach of the moving object; and a door opening permission unit configured to permit opening of the door by the door opening operation when the door opening operation is detected a predetermined number of times in a state in which the opening of the door is restricted.

  • Publication number: 20220259900
    Abstract: A vehicle door lock device includes: a first member moving from an initial position to an actuated position so as to switch a latch mechanism, from a latched state to an unlatched state; a second member moving between a mechanical link position and a mechanical link cut position; a third member linked to the second member and holding the second member at the mechanical link cut position and holding the second member at the mechanical link position; a driving force source selectively moving the third member to one of the first and second positions; an operating member moving from an initial position to an actuated position, and moving the third member from the first position to the second position; and a control unit driving the driving force source. The control unit drives the driving force source to move the third member from the first position to the second position.

  • Publication number: 20220170310
    Abstract: An obstacle detection device includes: an ultrasonic sensor signal processing unit detecting, of a distance to an obstacle and a shape of the obstacle, at least the distance based on an output of an ultrasonic sensor disposed in a door of a vehicle, the ultrasonic sensor detecting the distance within a predetermined detection range by ultrasonic waves; a camera image processing unit detecting at least one of the distance and the shape based on an output of a camera of the vehicle, the camera imaging an area including a trajectory range of the door when being opened and a detection range of the ultrasonic sensor; and a controller performing an opening operation control of opening the door to a pop-up position based on detection results of the ultrasonic sensor signal processing unit and the camera image processing unit when the distance is less than a predetermined distance.

  • Patent number: 11149475
    Abstract: A door device for a vehicle includes a latch drive device configured to unlatch a swing door by driving a latch mechanism, a door hold-open device configured to hold the swing door at an opened angle by applying a braking force to the swing door, a door open switch issuing an operation request of the latch drive device to open the swing door; a door stop switch issuing an operation request of the door hold-open device, and a grip portion including the door open switch and the door stop switch to issue the operation requests of the door open switch and the door stop switch in a state where an occupant of the vehicle holds the grip portion.

  • Publication number: 20210254390
    Abstract: A vehicle door control device applied to a vehicle including a swingably supported door and a door braking unit applying a braking force to the door includes: a braking control unit that executes a first braking processing of holding the braking force at a reference braking force for stopping the door and ending when an external force acting on the door is larger than the braking force, and a second braking processing of gradually increasing the braking force from the reference braking force after the first braking processing. The braking control unit executes, during execution of the second braking processing, a processing of eliminating the braking force when a situation where the external force is larger than the braking force continues, and executes a third braking processing of holding the braking force to be equal to or larger than the reference braking force when the situation does not continue.

  • Patent number: 10975609
    Abstract: A vehicle door apparatus includes: an opening and closing drive device capable of opening and closing a swing door provided in a vehicle; and a control device configured to control the opening and closing drive device. The control device includes: an occupant detection unit configured to detect an occupant of the vehicle who approaches the door; a first opening operation control unit configured to open the door to a first opening degree when the occupant has entered an opening control area from a proximal end side of the door; and a second opening operation control unit configured to open the door from the first opening degree to a second opening degree when the occupant has moved to a free end side of the door beyond an opening operation trajectory of the door.
