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.

Claims (24)

1 . A vehicle door lock device for a door of a vehicle, the vehicle door lock device comprising:

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, wherein 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,

determine whether a predetermined monitoring time period has expired since the mechanical changeover mechanism has switched from the mechanical lock mode to the mechanical unlock mode,

upon determining that the predetermined monitoring time period has expired, activate the actuator to cause the mechanical changeover mechanism to switch from the mechanical unlock mode to the mechanical lock mode, and

upon determining that one or more of the plurality of conditions for re-locking have been met before the predetermined monitoring time period has expired, immediately activate the actuator to cause the mechanical changeover mechanism to switch from the mechanical unlock mode to the mechanical lock mode.

2 . A vehicle door lock device for a door of a vehicle, the vehicle door lock device comprising:

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,

wherein 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,

wherein one of the plurality of conditions for re-locking is that a child lock, which prohibits the mechanical changeover mechanism from switching to the mechanical unlock mode, is set to ON for the door, and

wherein the controller is further configured to, when the controller has determined that the child lock has been set to ON for the door and the mechanical changeover mechanism has switched from the mechanical lock mode to the mechanical unlock mode according to an operation performed on an indoor door handle lever of the door, immediately activate the actuator to cause the mechanical changeover mechanism to switch from the mechanical unlock mode to the mechanical lock mode.

3 . The vehicle door lock device according to claim 1 ,

wherein one of the plurality of conditions for re-locking is that a current user is not an authorized user, and

wherein the controller is further configured to, when the controller has determined that the current user is not an authorized user 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.

4 . The vehicle door lock device according to claim 1 ,

wherein one of the plurality of conditions for re-locking is that a tilt angle of the vehicle has changed, and

wherein the controller is further configured to, when the controller has determined that the tilt angle has changed 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.

5 . The vehicle door lock device according to claim 4 ,

wherein the controller implements a plurality of control modes including an unlock control mode that prohibits the mechanical changeover mechanism from switching from the mechanical unlock mode to the mechanical lock mode, and

wherein the controller is further configured to, while the unlock control mode is selected, when the controller has determined that the tilt angle has changed and the mechanical changeover mechanism has switched from the mechanical lock mode to the mechanical unlock mode, keep the mechanical changeover mechanism in the mechanical unlock mode.
