The process which transmits either of these from the portable device transmission part 32 is performed. Further, when the portable device receiving unit 33 receives a request signal from the in-vehicle device 20, it outputs a preset key ID signal of the portable device 30.

Next, the processing flow of the in-vehicle device controller 21 will be described based on the flowchart of FIG.
First, in step S1, it is determined whether a lock command or an unlock command by either the keyless process or the remote control process has been made. If the command has been made, the process proceeds to step S2 to double the command. The lock operation processing is executed, that is, the main door lock actuators 11a to 14a and the sub door lock actuators 41 to 44 are driven to the locking side or the unlocking side according to a command.

Here, the keyless process and the remote control process will be briefly described.
First, the keyless process will be described. This keyless process is a process that does not involve the operation of both switches 34 and 35 of the portable device 30, and includes a keyless lock process and a keyless unlock process.

The keyless lock process is a process of locking when getting off the vehicle. In the first embodiment, two locking methods can be performed.
That is, in the first embodiment, when any one of the request switches 63a to 63d is pressed in a state where the portable device 30 exists in the preset detection area, and in the detection area, the preset is set in advance. Either the case where it goes out of the range is set as an operating condition, and when this operating condition is satisfied, the in-vehicle device control unit 21 automatically locks.

  The keyless unlock process is a process of automatically unlocking when the user carries the portable device 30 and operates any of the request switches 63a to 63d with the doors 1 to 4 being locked.

That is, in the first embodiment, when a signal indicating that any of the request switches 63 a to 63 d is operated is input to the in-vehicle device control unit 21, the request signal is transmitted from the in-vehicle device transmission unit 23 to the portable device 30.
When the portable device 30 receives the request signal, the portable device 30 transmits a key ID signal from the portable device transmission unit 32.
When the vehicle-mounted device 20 receives the key ID signal, the vehicle-mounted device 20 collates with the key ID registered in the vehicle.

Next, remote control processing will be described.
The remote control process is a process corresponding to the operation of each switch 34, 35 of the portable device 30, and there are a remote unlock process and a remote lock process.

The remote lock process is a process of automatically locking when the user presses the lock switch 35 of the portable device 30.
That is, when receiving a signal indicating that the lock switch 35 of the portable device 30 has been pressed, the in-vehicle device control unit 21 automatically locks after confirming the key ID signal included in the signal.

The remote unlocking process is a process of automatically unlocking when the user operates the unlocking switch 34 of the portable device 30.
That is, when receiving a signal indicating that the unlocking switch 34 of the portable device 30 has been pressed, the in-vehicle device control unit 21 automatically unlocks after confirming the key ID signal included in the signal. Do.
The keyless process and the remote control process in step S1 of FIG. 5 are the processes described above. In the first embodiment, when a locking instruction and an unlocking instruction for executing any of the processes are performed, A double lock operation process for driving the main door lock actuators 11a to 14a and the sub door lock actuators 41 to 44 is executed.

  If NO is determined in step S1, the process proceeds to step S3, and based on the output of the key cylinder switch 62, the locking operation by either the key cylinder 107 or the lock knob 106 of the driver's door 1 is performed. When it is determined that the unlocking operation has been performed, and these operations have been performed, the process proceeds to step S4, and the single lock that drives the main door lock actuators 11a to 14a to the locking side or the unlocking side according to the operation. Perform the activation process.

  In other words, the doors 1 to 4 can be mechanically locked / unlocked independently by operating the key cylinder 107 or the lock knob 106 of each door 1 to 4. When the cylinder 107 or the lock knob 106 is operated, the door locks 11 to 14 of all the doors 1 to 4 are automatically locked and unlocked in conjunction with this operation.

If NO is determined in step S3, the process proceeds to step S5 to determine whether the operation of the central door lock switch 61 is performed. If this operation is performed, the process proceeds to step S4 to execute the single lock operation process. .
When the operation of the central door lock switch 61 is not performed, one flow is finished and the determination from step S1 is repeated.

  Next, the operation in the case of locking and unlocking in the vehicle door lock switch A of the first embodiment will be described.

First, an operation for locking and unlocking in the boarding state will be described.
In this way, locking and unlocking in the boarding state can be performed by locking and unlocking the lock knob 106 of each door 1 to 4 and locking and unlocking operation of the central door lock switch 61.

  Here, the doors 2 to 4 other than the driver's door 1 can be manually locked and unlocked individually by operating the lock knob 106, but when the lock knob 106 of the driver's door 1 is locked and unlocked, When the central door lock switch 61 is locked and unlocked, all the doors 1 to 4 are automatically locked and unlocked.

  That is, when the lock knob 106 of the driver's door 1 is locked and unlocked and when the central door lock switch 61 is locked and unlocked, in the flowchart of FIG. 5, step S1 → step S3 → step S4 Based on the single lock operation process, the main door lock actuators 11a to 14a are driven to the locked and unlocked side, and all the door locks 11 to 14 are switched to the locked and unlocked state.

As described above, when the vehicle is locked, the main door lock actuators 11a to 14a are driven and only the door locks 11 to 14 are locked.
Since the unlocking operation in this case is a manual unlocking operation of the lock knob 106 or the unlocking operation of the central door lock switch 61, the operation is simple.
Moreover, what is necessary is just to unlock | release one of the door locks 11-14 of each door 1-4 when rescuing a passenger | crew from the outside in this locked state.

Next, the operation in the case of locking when getting off will be described.
When locking in the state of getting off, an operation using the key cylinder 107 and an operation using the portable device 30 and each of the request switches 62a to 63d are possible.

  Here, when the key cylinder 107 of the driver's seat door 1 is locked, a single lock operation process is performed by the flow of steps S3 → S4, all the door lock actuators 11a to 14a are driven, and the door locks 11 to 14 are locked. Is done.

  On the other hand, in the unlocked state, the user performs a keyless command operation such as whether the user is away from a preset distance from the vehicle while holding the portable device 30 or pressing the request keys 63a to 63d. When the remote control command operation is performed by operating each of the switches 34 and 35, the double lock operation process is executed by the flow from step S1 to step S2, and the main door lock actuators 11a to 14a and the sub door lock actuators are executed. 41 to 44 are driven to the locking side.

  Accordingly, the door locks 11 to 14 are locked, and the operation unit 50 of the sub door lock actuators 41 to 44 is engaged with the vehicle body.

Thus, at the time of locking by the double lock operation process, in addition to the door locks 11 to 14 being in a locked state, the operation part 50 of the sub door lock actuators 41 to 44 is engaged with the vehicle body.
Therefore, even if the thief can unlock the door locks 11 to 14 by destroying the key cylinder 107 or the like, the engagement of the operation part 50 of the sub door lock actuators 41 to 44 cannot be released. Can't open 1-4.
Therefore, the anti-theft performance is improved.

Next, the operation in the case of unlocking when getting off will be described.
First, when unlocking only the door locks 11 to 14 by the single lock operation process, the key cylinder 107 can be unlocked by the unlocking operation, the keyless process, and the remote control process.

  When the unlocking operation of the key cylinder 107 is performed, the main door lock actuators 11a to 11d are driven and the door locks 11 to 14 are unlocked based on the single lock operation process in the flow of steps S1, S3, and S4. Is done.

  On the other hand, when the unlocking operation is performed by either the keyless process or the remote control process, the main door lock actuators 11a to 14a and the sub door lock actuator are based on the double lock operation process by the flow of steps S1 → S2. 41 to 44 are driven to the unlocking side. In this case, the sub door lock actuators 41 to 44 are originally driven to the unlocking side, so that substantial driving is not performed.

  Further, in the case of unlocking from the locked state of the door locks 11 to 14 and the sub door lock actuators 41 to 44 by the double lock operation process, the unlocking operation can be performed by either the keyless process or the remote control process. is there.

  When the unlocking operation by the keyless process and the remote control process is performed, the main door lock actuators 11a to 14a and the sub door lock actuators 41 to 44 are driven to the unlocking side based on the process from step S1 to S2.

  When the door locks 11 to 14 are locked and the sub door lock actuators 41 to 44 are engaged, even if the key cylinder 107 is operated, the door locks 11 to 14 are only unlocked. Yes, the sub-door lock actuators 41 to 44 cannot be disengaged from the vehicle body, and the doors 1 to 4 cannot be opened.

As described above, in the vehicle door lock switch of the first embodiment, in addition to the door locks 11 to 14, the sub door lock actuators 41 to 44 that can form a state where the doors 1 to 4 are engaged with the vehicle body. Is set, and the sub door lock actuators 41 to 44 are set in a locked state in parallel with the door locks 11 to 14 at the time of locking in the passenger getting off state.
For this reason, even if the door locks 11 to 14 can be unlocked by breaking the key cylinder 107 or the like, the engagement by the sub door lock actuators 41 to 44 cannot be released, and the antitheft performance is improved.

  On the other hand, at the time of locking in the boarding state, the sub door lock actuators 41 to 44 are in a non-engaged state as locking only the door locks 11 to 14. Therefore, as in the prior art, it can be unlocked by manual unlocking operation of the lock knob 106 or the central door lock switch 61, and it is easy to use and does not deteriorate the escape performance when the occupant is rescued.

Further, since the main door lock actuators 11a to 14a of all the doors 1 to 4 are driven in conjunction with ON / OFF of the key cylinder switch 62 that is interlocked with manual operation of the key cylinder 107 and the lock knob 106, the convenience is increased. Excellent.
On the other hand, when the key cylinder 107 and the lock knob 106 are manually operated, a single lock operation process is performed. Therefore, even when the operating force transmission mechanism 105 is operated to the unlocking side due to the destruction of the key cylinder 107 or the like, the sub door The engagement by the lock actuators 41 to 44 cannot be released.
Thus, in conjunction with the key cylinder operation, it is possible to improve the convenience by locking and unlocking all the doors 1 to 4, while ensuring high antitheft performance.

  Next, a vehicle door lock switch according to Example 2 of the embodiment of the present invention will be described with reference to FIGS. Since the second embodiment is a modification of the first embodiment, only the difference will be described, and the description of the same configuration and operational effects as the first embodiment will be omitted.

  In the second embodiment, the sub door lock actuators 41 to 44 can be driven by operating the key cylinder 107, but the sub door lock actuators 41 to 44 cannot be driven by the destruction of the key cylinder 107 or the like. The anti-theft performance is ensured.

Specifically, the processing contents by the in-vehicle device control unit 21 are different from those in the first embodiment.
That is, as shown in the flowchart of FIG. 6, it is determined whether or not a predetermined cryptographic operation has been performed in step S201 that is performed when the key cylinder 107 or the lock knob 106 is locked and unlocked, and the cryptographic operation is not performed. In the same manner as in the first embodiment, the process proceeds to step S4 to execute the single lock operation process for driving the main door lock actuators 11a to 14a. However, if the cryptographic operation is performed, the process proceeds to step S2. A double lock operation process for driving the main door lock actuators 11a to 14a and the sub door lock actuators 41 to 44 is executed.

This encryption is formed from an n-digit encryption code set in advance based on the number of times the key cylinder switch 62 is turned ON / OFF.
In the case of the second embodiment, this encryption code is set by the number of times the key cylinder 107 is turned on. For example, when the 3-digit encryption code is 3-2-4, the key for turning on the key cylinder switch 62 is set. The unlocking operation of the cylinder 107 is performed three times, two times, and four times with an interval T ₀ longer than a set time (for example, around 1 second). As a result, an output as shown in FIG. 7 is made, and the output state shown in FIG. 7 becomes an encryption code of 3-2-4.

  In the vehicle door lock device of the second embodiment, the key cylinder 107 is operated even in the double lock state in which the door lock actuators 11a to 14a and 41 to 44 are driven by keyless processing or remote control processing. By outputting the encryption code, unlocking can be performed.

  Therefore, even if transmission from the portable device 30 becomes impossible due to the battery running out of the portable device 30, etc., it can be unlocked.

  Further, in the double lock state, it is difficult to release the engagement of the sub door lock actuators 41 to 44 because the encryption code cannot be output simply by destroying the key cylinder 107. Theft prevention performance can be secured.

  As described above, the embodiment of the present invention and Examples 1 and 2 have been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment and Examples 1 and 2, and the present invention is not limited thereto. Design changes that do not depart from the gist are included in the present invention.

  For example, in the first and second embodiments, an example in which the present invention is applied to a so-called four-door type vehicle MB is shown. However, the applicable vehicle type is not limited to this, and other than the four-door type, two-door, three-door, five-door, etc. It can also be applied to other vehicles.

  Moreover, although the door has illustrated the hinge door in Example 1, 2, it is applicable also to other types of doors, such as a slide door.

  In the first and second embodiments, the auxiliary door actuator is installed in the door, but can be installed in the vehicle body.
