The in-vehicle device 2 is provided in the vehicle, communicates with the portable device 3, performs ID authentication, and outputs a signal for unlocking the door when a new ID is authenticated, When it is not authenticated, it outputs a signal to lock the door. Thus, the operation of a so-called keyless system is performed. The control is executed by a built-in controller 21 (corresponding to setting storage means).
Furthermore, a signal for double-locking the door is output by a specific operation from the portable device 3 or the passenger compartment.

The portable device 3 is large enough to be carried by a user of the vehicle, communicates with the vehicle-mounted device 2, and transmits ID data and authenticates the ID when communication is possible.
The door lock device 4 drives and controls a door lock actuator (not shown) to lock, unlock, and deadlock the door.

Furthermore, in the vehicle door lock device 1 according to the first embodiment, information is obtained from a sensor provided in the vehicle or an existing vehicle device as shown in FIG. This will be described below.
An IGN switch ON / OFF signal is obtained from the IGN switch 5 to grasp the state of the IGN switch 5.
From the brake device 6, an on / off signal of a parking brake (side brake) is obtained, and the state of the parking brake is grasped.
The door / trunk opening / closing switch 7 (corresponding to the door opening / closing detection means) obtains a door / trunk opening / closing signal and grasps whether the door / trunk has been opened / closed.

Next, the operation will be described.
[Double lock processing]
FIG. 2 is a flowchart showing the flow of a double lock process executed by the controller 21 of the in-vehicle device 2 of the vehicle door lock device of the first embodiment. Each step will be described below.

  In step S1, it is determined whether or not the double lock is locked by the user's operation. If the double lock is locked, the process proceeds to step S2, and if the double lock is not locked, the process proceeds to step S10.

  In step S2, it is determined whether or not there has been a specific switch operation from the passenger compartment. If there is a specific operation, the process proceeds to step S3, and if there is no specific operation, the process proceeds to step S6.

  In step S3, the door lock actuator is driven and unlocked to release the double lock state.

  In step S4, it is determined whether or not all doors have been closed from a state in which any door is open. If all doors have been closed, the process proceeds to step S5. If not, the process proceeds to step S8.

  In step S5, the door lock actuator is driven and controlled to be in a double lock state, and the process is terminated.

  In step S6, it is determined whether or not there is an unlocking operation from outside the vehicle, for example, an operation request from the portable device 3. If there is an unlocking operation, the process proceeds to step S7, and if there is no unlocking operation, the process proceeds to step S9. move on.

  In step S7, the door lock actuator is driven and controlled to unlock the double lock state.

  In step S8, the state in which the double lock is released is maintained as it is, and the process ends.

  In step S10, the state in which the double lock is released is maintained as it is, and the process ends.

[Improves theft prevention effect]
In the vehicle door lock device 1 of the first embodiment, when a person is in the vehicle and wants to go outside when double locking is performed, if a specific operation is performed from the passenger compartment, the steps S2 and S3 are performed. Since the double lock state is released by the processing, the user can go outside.
At this time, conventionally, the double lock and the door lock cannot be operated unless the double lock operation is performed again by the operation of the person holding the portable device 3 or the like. In the lock device, when the double lock is released, the doors are opened and the doors are opened, and all the doors are closed, there is no operation of the person holding the portable device 3 again by the processing of step S4 and step S5. Is double-locked again.

  As a result, the anti-theft effect can be enhanced while improving convenience by smoothly returning to the double-locked state.

In other words, for example, when a person is left in the passenger compartment and the driver leaves the vehicle, if possible, the user wants to leave in a double lock state in which a high antitheft effect can be obtained.
However, as in the past, after a double lock is performed, if a person who remains in the vehicle interior releases the double lock and goes out of the vehicle interior, the driver will leave the vehicle with peace of mind. I can't.

The driver of the vehicle using the vehicle door lock device 1 according to the first embodiment can leave the vehicle with peace of mind if only a specific operation is taught even if a person is left in the passenger compartment.
This is because even if a person inside the vehicle subsequently goes outside the vehicle, the vehicle is again double-locked if all the doors are closed.

  In addition, even if there is a person remaining in the passenger compartment when the vehicle is in the double lock state again, the processing of steps S1 to S2 is executed again. Therefore, if it is desired to go outside the vehicle, a specific operation may be performed. There is no problem. That is, in the vehicle door lock device of the first embodiment, once the double lock state is established, the double lock state can be well maintained, so that the antitheft effect can be kept higher.

  Further, the first embodiment will be further described here. In the first embodiment, the IGN switch 5 indicates the on / off status of the IGN, and the brake device 6 indicates the status of the foot brake and the parking brake. Can know. Further, the door / trunk opening / closing switch 7 can know the open / closed state of each door and trunk as described above.

Thereby, the controller 21 of the vehicle-mounted device 2 can determine the situation as to whether or not the locking to the double lock state may be performed more appropriately.
In other words, the vehicle door lock device according to the first embodiment increases the anti-theft effect by extending the period of the double lock state by returning to the double lock state. Therefore, the means for determining whether or not to perform an accurate double lock as described above is indispensable, and by implementing both, it is convenient for the user and has an antitheft effect. It becomes a high vehicle.

  When the double lock is not locked, the process proceeds from step S1 to S10, and the state where the double lock is released is maintained.

Next, the effect will be described.
In the vehicle door lock device of the first embodiment, the following effects can be obtained.
