Description

  The present invention relates to a vehicular locking device that locks a door lock based on wireless communication with a portable device.

  In general, in order to improve the usability of a vehicle, a vehicle that transmits a radio signal from the portable device by operating the portable device possessed by the user and electrically locks and unlocks the door lock on the condition that the wireless signal is received. A locking device has been proposed.

  In such a vehicle locking device, when the door can be locked by operating the portable device when the door is open, the door is locked when the door is closed while the portable device is placed in the vehicle compartment. In such an open state of the door, locking of the door lock by operating the portable device is prohibited.

  Further, in this type of vehicle locking device, there has been proposed a device equipped with an automatic lock function that automatically locks the door lock when the unlocked state of the door lock elapses for a certain time. In the vehicle locking device equipped with such an automatic lock function, it is possible to prevent the vehicle from being left unattended while the door lock is unlocked, and the security level of the vehicle can be ensured. Specifically, for example, in the vehicle locking device disclosed in Patent Document 1, when the unlocking operation by the portable device is performed a plurality of times with a predetermined time in a state where the ignition key is not attached and the door is fully closed. Is set to automatic lock mode. The vehicle locking device automatically locks the door lock when a predetermined time has elapsed after the door opening / closing operation is performed in the automatic lock mode. Further, when the ignition key is attached before the predetermined time elapses, the automatic lock mode is released.

In other words, in such a vehicle locking device, the door lock can be automatically locked when the subsequent predetermined operation (get-off operation) is completed by an operation (reservation operation) at a stage prior to the timing of actually locking the door lock. It will be possible. For this reason, in this vehicle locking device, usability can be improved while ensuring a high security level.
JP-A-10-196181

  However, in such a vehicle locking device, since it is necessary to operate the portable device a plurality of times as a reservation operation in order to set the automatic lock mode, the operability is somewhat difficult. However, it is very difficult in the control of Patent Document 1 to shift to the automatic lock mode by a single operation in order to eliminate such inconvenience. In addition, when the portable device is operated in the vehicle compartment, the user may get locked if the user gets off the vehicle while leaving the portable device in the vehicle compartment. Therefore, there is still room for improvement in this respect.

  This invention is made | formed in view of such a situation, The objective is to provide the locking device for vehicles which can aim at the improvement of the usability with respect to locking of a door lock, suppressing generation | occurrence | production of an interlock. .

  In order to solve the above-described problem, in the invention according to claim 1, a communication locking function for locking the door lock when receiving a lock operation signal wirelessly transmitted from the corresponding portable device in a closed state of all doors. The vehicle locking device has a door lock reservation mode when the lock operation signal is received when the door is open, and all doors are closed in the door lock reservation mode. The gist is to automatically lock the door lock.

  According to the above configuration, when a lock operation signal is received from the portable device in the open state of the door, the door lock reservation mode is set. In the door lock reservation mode, the door lock is automatically locked when all the doors are closed. For this reason, for example, when there is a passenger in addition to the owner (driver) of the portable device, the driver sends a locking operation signal from the portable device even if the other passenger's door is open. By transmitting, it becomes possible to lock the door lock without performing the locking operation thereafter. That is, the driver can lock the door lock without waiting for the passenger to close the door until the passenger closes the door. Further, by not locking the door lock when receiving the locking operation signal in the door open state, it is possible to prevent the door lock from being locked while the portable device is left in the vehicle compartment. Therefore, it is possible to improve the usability for locking the door lock while suppressing the occurrence of the interlock.

  According to a second aspect of the present invention, in the vehicle locking device according to the first aspect, in the door lock reservation mode, a preset delay time has elapsed after all doors are closed. The gist is to automatically lock the door lock on the condition.

  According to the above configuration, in the door lock reservation mode, in addition to the fact that all the doors are in the closed state, the fact that the delay time has elapsed thereafter is also a locking condition for the door lock. For this reason, there will be a grace period between when all doors are closed and when the doors are locked. For example, when the driver unintentionally enters the door lock reservation mode. It is possible to suppress the door lock from being locked.

The gist of the invention described in claim 3 is that the vehicle locking device described in claim 1 or claim 2 is notified of that in the door lock reservation mode.
According to the above configuration, when the door lock reservation mode is entered, this is notified until at least all doors are closed, so the owner of the portable device is certain whether or not it is in the door lock reservation mode. Can be recognized. In addition, by notifying, it is possible to prevent the portable device from being left behind in the vehicle compartment. Furthermore, if the notification is performed even after the door is closed until the door lock is locked, the effect of suppressing the interlock is further improved.

  According to a fourth aspect of the present invention, in the vehicle locking device according to any one of the first to third aspects, the door is open even if the locking operation signal is received when the driver's door is open. The main point is not to shift to the lock reservation mode.

  According to the above configuration, the vehicle locking device does not shift to the door lock reservation mode when the driver's seat door is in the open state. That is, the vehicle locking device is in the door lock reservation mode only when the locking operation signal is received from the portable device in the open state of the doors (passenger seat door and rear seat door) other than the driver seat door. Usually, since the portable device is carried by the driver, it is difficult for the driver to position the portable device in the vehicle interior after transmitting the locking operation signal from the portable device when the driver's seat door is closed. . Therefore, it is possible to further suppress the door lock being locked while the portable device is left behind in the vehicle compartment.

  In the invention according to claim 5, in the vehicle locking device according to any one of claims 1 to 4, when the driver's seat door changes from a closed state to an open state in the door lock reservation mode, The gist is to cancel the door lock reservation mode.

  According to the above configuration, when the driver's seat door changes from the closed state to the open state in the door lock reservation mode, the door lock reservation mode is canceled. Therefore, it is easy to cancel the door lock reservation mode, and it is possible to prevent the portable device from being left in the vehicle compartment due to the opening of the driver's seat door. Therefore, it is possible to further prevent the door lock from being locked while the portable device is left behind in the vehicle compartment.

  As described above in detail, according to the present invention, it is possible to provide a vehicle locking device that can improve the usability of locking a door lock while suppressing the occurrence of an interlock.

Hereinafter, an embodiment embodying the present invention will be described in detail with reference to FIGS. 1 and 2.

<Configuration of portable device 10>
The portable device 10 has a wireless communication function and can transmit a wireless signal. Specifically, the portable device 10 includes a communication control unit 11 configured by a computer unit including a CPU, a ROM, a RAM, and the like, a transmission unit 12 electrically connected to the communication control unit 11, and the portable device 10. And an operation unit 13 provided on the design surface and operable by a user.

The communication control unit 11 includes a nonvolatile memory 11M in which a unique ID code is recorded.
The operation unit 13 includes, for example, a push button switch, and includes a locking operation unit 13a for performing a locking operation and an unlocking operation unit 13b for performing an unlocking operation. When the operation unit 13 is operated, the operation signals (locking operation signal, unlocking operation signal) are input to the communication control unit 11.

  When the communication control unit 11 receives a locking operation signal or an unlocking operation signal from the operation unit 13, the communication control unit 11 includes a corresponding locking code or unlocking code and an ID code recorded in the memory 11M. Is output to the transmission unit 12.

When the locking / unlocking operation signal is input from the communication control unit 11, the transmitting unit 12 modulates the locking / unlocking operation signal into a radio wave having a predetermined frequency and transmits the modulated signal to the outside.
<Configuration of vehicle locking device 20>
As shown in FIG. 1, the vehicle locking device 20 includes a locking / unlocking control unit 21 configured by a computer unit including a CPU, a ROM, a RAM, and the like. A receiving unit 22 is electrically connected to the locking / unlocking control unit 21.

  The receiving unit 22 can receive the locking / unlocking operation signal transmitted from the portable device 10. When receiving the locking / unlocking operation signal, the receiving unit 22 demodulates the signal into a pulse signal and outputs the pulse signal to the locking / unlocking control unit 21. .

  The locking / unlocking control unit 21 includes a nonvolatile memory 21M, and an ID code equivalent to the ID code set in the corresponding portable device 10 is recorded in the memory 21M. The locking / unlocking control unit 21 is electrically connected to a notification device 23 and a door lock device 24. In addition, the alarm device 23 is configured to ring in different modes based on the first operation signal and the second operation signal input from the locking / unlocking control unit 21. The door lock device 24 is a device that automatically locks and unlocks the door using an actuator. When the unlock signal is input from the lock control unit 21, the door lock is unlocked and the lock signal is input. Then, the door lock is locked and a lock / unlock state signal indicating the lock / unlock state of the door lock is output to the lock / unlock control unit 21. For this reason, the locking / unlocking control unit 21 can recognize the locking / unlocking state of the door lock based on the locking / unlocking state signal input from the door lock device 24.

  Each door courtesy switch that detects the open / closed state of each door of the vehicle 2 is electrically connected to the locking / unlocking control unit 21, and the locking / unlocking control unit 21 is based on an input signal from the door courtesy switch. The open / closed state of the door can be recognized.

  Then, the lock / unlock control unit 21 performs door lock control for driving and controlling the door lock device 24 based on the open / close state of each door and the lock / unlock operation signal from the portable device 10. The door lock control performed by the locking / unlocking control unit 21 will be described with reference to the flowcharts shown in FIGS.

<Door Lock Control by Locking / Unlocking Control Unit 21>
As shown in FIG. 2, when the locking / unlocking control unit 21 first receives a locking / unlocking operation signal from the portable device 10 by the receiving unit 22 in step S1, it determines whether all the doors are closed in step S2. To do. Specifically, when the locking / unlocking operation signal is input from the receiving unit 22 in step S1, the locking / unlocking control unit 21 calculates the ID code included in the locking / unlocking operation signal and the ID code recorded in the memory 21M. Collation is performed, and when the collation is established, it is recognized as a locking / unlocking operation signal from the corresponding portable device 10. In step S2, the locking / unlocking control unit 21 determines whether all the doors are closed based on an input signal from each door courtesy switch. As a result, when it is determined that all the doors are in the closed state, the locking / unlocking control unit 21 proceeds to the process of step S3 and performs locking / unlocking of the door lock based on the locking / unlocking operation signal. Specifically, when the locking / unlocking operation signal includes a locking code, the locking / unlocking control unit 21 outputs a locking signal to the door lock device 24 to lock the door lock, and the unlocking code is If it is included, an unlock signal is output to the door lock device 24 to unlock the door lock, and the process here is temporarily terminated.

  On the other hand, if the locking / unlocking control unit 21 determines in step S2 that all doors are not closed, it determines whether or not the driver's seat door is open in step S4. As a result, when it is determined that the driver's seat door is in the open state, the locking / unlocking control unit 21 temporarily ends the process, and when it is determined that the driver's seat door is in the closed state, step S5 is performed. Move on to processing.

  In step S5, the locking / unlocking control unit 21 determines whether the locking / unlocking operation signal received by the receiving unit 22 is a locking operation signal including a locking code. As a result, when the locking / unlocking control unit 21 determines that the locking / unlocking operation signal is not the locking operation signal, that is, the unlocking operation signal including the unlocking code, the processing here is temporarily terminated. If it is determined that the signal is a locking operation signal, the process proceeds to the door lock reservation mode in step S6.

  That is, when the lock / unlock control unit 21 receives the lock / unlock operation signal from the portable device 10 in the closed state of all doors by the receiving unit 22, the lock / unlock control unit 21 is based on the lock code or the unlock code included in the lock / unlock operation signal. Lock and unlock the door lock. On the other hand, when the locking / unlocking control unit 21 receives the locking / unlocking operation signal (locking operation signal) including the locking code in the open state of the doors other than the driver's door, the receiving unit 22 enters the door lock reservation mode.

  And if it transfers to door lock reservation mode, the locking / unlocking control part 21 will output a 1st operation signal with respect to the alerting | reporting device 23 in step S7, and will make the 1st alerting | reporting sound generate | occur | produce from this alerting | reporting device 23. Thereafter, when the locking / unlocking control unit 21 determines in step S8 that all the doors have been closed, in step S9, the locking / unlocking control unit 21 outputs a second operation signal to the notification device 23 to output a second notification sound from the notification device 23. And a timer is started in step S10. For this reason, the user can recognize that the locking / unlocking control unit 21 has shifted to the door lock reservation mode by the first notification sound, and recognizes that all the doors have been closed by the second notification sound. can do.

  After the timer is started, the locking / unlocking control unit 21 determines whether or not doors other than the driver's seat door are opened in step S11. If the determination is affirmative, the process proceeds to step S7 again. If there is, the process proceeds to step S12 shown in FIG.

  In step S <b> 12, the locking / unlocking control unit 21 determines whether or not the receiving unit 22 has received the locking operation signal from the portable device 10 again after the timer is started. If the result is negative, the locking / unlocking control unit 21 determines whether or not the driver's seat door is open in step S13. As a result, if it is determined that the driver's seat door is not in the open state, the locking / unlocking control unit 21 determines whether or not a preset delay time (here, 5 seconds) has elapsed after the timer is started in step S14. Determine whether. As a result, when it is determined that 5 seconds have not elapsed, the locking / unlocking control unit 21 proceeds to the process of step S11 again. When it is determined that 5 seconds have elapsed, the locking signal is output to the door lock device 24 at step S15. Is output to lock the door lock, and the processing here is temporarily terminated. Note that the delay time is not limited to 5 seconds.

  For this reason, the owner (driver) of the portable device operates the locking operation unit 13a of the portable device 10 in the open state of the door other than the driver's seat door, thereby setting the locking / unlocking control unit 21 to the door lock reservation mode. If all the doors are closed in this door lock reservation mode, the door lock can be automatically locked 5 seconds later without any operation.

  On the other hand, if the locking / unlocking control unit 21 determines in step S12 that the locking operation signal has been received by the receiving unit 22, or if it is determined in step S13 that the driver's seat door has been opened, the door is unlocked in step S16. The lock reservation mode is canceled and the processing here is temporarily terminated. For this reason, the driver can operate the locking operation unit 13a of the portable device 10 again or open the driver's seat door even after the locking / unlocking control unit 21 shifts to the door lock reservation mode. The door lock reservation mode can be canceled.

Therefore, according to the present embodiment, the following effects can be obtained.
(1) By operating the locking operation part 13a of the portable device 10 in the open state of doors other than the driver's seat door, the vehicle locking device 20 can be set to the door lock reservation mode. In the door lock reservation mode, when all the doors are closed and a preset delay time (5 seconds in the present embodiment) elapses, the door lock is automatically locked. For this reason, for example, when there is a passenger in addition to the owner (driver) of the portable device 10, the driver can lock the portable device 10 even if the other passenger's door is open. By operating the portion 13a, the door lock can be locked without performing a locking operation thereafter. That is, the driver can lock the door lock without waiting for the passenger to close the door until the passenger closes the door. Further, by not locking the door lock when the lock operation signal is received in the door open state, it is possible to prevent the door lock from being locked while the portable device 10 is left in the room of the vehicle 2. Therefore, it is possible to improve the usability for locking the door lock while suppressing the occurrence of the interlock.

  (2) In the door lock reservation mode, in addition to the fact that all the doors are closed, the delay time (5 seconds) thereafter is also a locking condition for the door lock. For this reason, there will be a grace period between when all doors are closed and when the doors are locked. For example, when the driver unintentionally enters the door lock reservation mode. It is possible to suppress the door lock from being locked.

  (3) When in the door lock reservation mode, the locking / unlocking control unit 21 notifies that effect by operating the alarm 23 until all the doors are closed. For this reason, the driver can reliably recognize whether or not the vehicle locking device 20 is in the door lock reservation mode by the notification sound generated from the notification device 23. Moreover, it can suppress that a driver | operator misplaces the portable device 10 in the room | chamber interior of the vehicle 2 by alerting | reporting.

  Furthermore, when all the doors are in the closed state in the door lock reservation mode, the notification sound changes to a different one (changes from the first notification sound to the second notification sound), so that the effect of suppressing the interlock is further improved.

  (4) When the driver's seat door is in the open state, the vehicle locking device 20 does not shift to the door lock reservation mode even if it receives a locking operation signal from the portable device 10. That is, the vehicle locking device 20 enters the door lock reservation mode only when the locking operation signal is received from the portable device 10 in the open state of the doors (passenger seat door and rear seat door) other than the driver seat door. Usually, since the portable device 10 is carried by the driver, the driver places the portable device 10 in the vehicle compartment after transmitting the locking operation signal from the portable device 10 in the closed state of the driver's seat door. It becomes difficult to let you. Therefore, it is possible to further prevent the door lock from being locked while the portable device 10 is left behind in the vehicle 2.

  (5) When the driver's seat door changes from the closed state to the open state in the door lock reservation mode, the locking / unlocking control unit 21 cancels the door lock reservation mode. Therefore, it is easy to cancel the door lock reservation mode, and it is possible to prevent the portable device 10 from being left in the vehicle compartment due to the opening of the driver's seat door. Therefore, it is possible to further prevent the door lock from being locked while the portable device 10 is left behind in the vehicle 2.

In addition, you may change embodiment of this invention as follows.
In the above embodiment, in the door lock reservation mode, the lock / unlock control unit 21 locks the door when a preset delay time (5 seconds) has elapsed after all the doors are closed. It is designed to be locked. However, such a delay time is not necessarily set, and the locking / unlocking control unit 21 may immediately lock the doors when all the doors are closed. In this case, the operation of the alarm device 23 based on the second operation signal is not necessary.

  -In the said embodiment, the locking / unlocking control part 21 is alert | reported in a respectively different aspect by outputting a 1st operation signal and a 2nd operation signal to the alerting | reporting device 23 according to a condition. However, such notification is not necessarily different, and notification may be performed in the same manner. Further, the notification itself may be omitted.

  ・ The delay time is counted from the time when all doors are closed in the door lock reservation mode. However, the delay time may be timed from the time when the door lock reservation mode is entered, for example. In this case, the locking / unlocking control unit 21 may cancel the door lock reservation mode when all the doors are not closed before the delay time elapses. In this case, it is desirable that the delay time is set longer than that in the above embodiment.

  The locking / unlocking control unit 21 may shift to the door lock reservation mode even when the receiving unit 22 receives the locking operation signal from the portable device 10 in the open state of the driver's seat door.

  The locking / unlocking control unit 21 may be configured not to cancel the door lock reservation mode even when the driver's seat door changes from the closed state to the open state in the door lock reservation mode. Moreover, even when the locking / unlocking control unit 21 receives the locking / unlocking operation signal from the portable device 10 again by the receiving unit 22 in the door lock reservation mode, the door lock reservation mode may not be canceled. . That is, the condition for canceling the door lock reservation mode may be changed to another condition, for example, an ignition key is attached to a key cylinder for starting the engine.
