  • Publication number: 20240328212
    Abstract: A vehicle door lock device for a door of a vehicle includes: a mechanical changeover mechanism switchable between a mechanical lock mode in which a motion of a door handle lever is not transmitted to a latch and a mechanical unlock mode in which the motion of the door handle lever is transmitted to the latch; an actuator capable of causing the mechanical changeover mechanism to switch from the mechanical unlock mode to the mechanical lock mode; and a controller configured to control the actuator. The controller is configured to, when the controller has determined that any one of a plurality of conditions for re-locking is met and the mechanical changeover mechanism has switched from the mechanical lock mode to the mechanical unlock mode, immediately activate the actuator to cause the mechanical changeover mechanism to switch from the mechanical unlock mode to the mechanical lock mode.

  • Publication number: 20240287837
    Abstract: A vehicle door control system includes a door, holding part, and controller. The door is capable of opening and closing by a motion of swinging relative to a vehicle body. The holding part is capable of switching between an openable-and-closable state and a holding state. The openable-and-closable state is a state in which movement of the door in an opening direction that opens the door and movement of the door in a closing direction that closes the door are allowed. The holding state is a state in which movement of the door in the opening direction is prohibited and movement of the door in the closing direction is allowed. The controller is configured to control the holding part. The controller is configured to set the holding part to the holding state in response to the door stopping its movement while the door is open.
