You can see what was done.

  The operation of locking and unlocking the vehicle 10 with the above configuration will be described based on the sequence diagram of FIG. Since the locking and unlocking operations are performed by substantially the same control, the unlocking operation will be described here, and the locking operation will be omitted. In addition, “a” is attached to the operation of the mobile phone 70 and “b” is attached to the operation of the vehicle 10 in the notation of the symbols indicating each step.

  First, when the user operates the electronic key operation unit 84 of the mobile phone 70 and inputs an unlocking request to the wireless lock device 20 of the vehicle 10 (S10a), the key control unit 81 is stored in the ID storage unit 82. An unlock request signal in which the stored authentication code and unlock request are superimposed is transmitted to the vehicle 10 (wireless lock device 20) as a predetermined radio signal (S12a).

  In the wireless lock device 20 of the vehicle 10, the request acquisition unit 36 of the lock communication unit 34 constantly monitors a radio signal from the mobile phone 70. When the request acquisition unit 36 detects and receives the release request signal (S14b), the request acquisition unit 36 notifies the lock control unit 30 of the authentication code and the release request that are the received contents, and the lock control unit 30 acquires the notification ( S16b).

  Subsequently, the lock control unit 30 compares the authentication code stored in the authentication storage unit 50 with the received authentication code and determines whether or not they match (S18b). If the two authentication codes do not match (N in S18b), the lock control unit 30 determines that it is an unlocking request for another vehicle and enters the standby state again.

  When the two authentication codes match (Y in S18b), the lock control unit 30 drives the lock mechanism 22 to unlock (S20b).

  When unlocking is completed in the process of S20b, the lock control unit 30 instructs the answerback control unit 40 to perform a predetermined answerback. Here, the answer back control unit 40 instructs the notification unit 38 to notify the mobile phone 70 that the unlocking is completed, and the notification unit 38 receives the instruction, and the authentication code in the authentication storage unit 50 is received. And the unlocking completion signal on which the unlocking completion is superimposed is output to the mobile phone 70 (S22b).

  On the other hand, when receiving the unlocking completion signal transmitted from the vehicle 10 (S24a), the electronic key communication unit 83 of the mobile phone 70 compares the authentication code included in the unlocking completion signal with the authentication code of the ID storage unit 82. Then, it is determined whether or not these authentication codes match (S26a).

  If the authentication codes do not match (N in S26a), the mobile phone 70 (electronic key function unit 80) determines that it is not a target vehicle release completion signal, and enters a standby state without performing any special operation.

  If the authentication codes match (Y in S26a), the key control unit 81 determines that an unlocking completion notification has been received from the vehicle 10, and either the display unit 75 of the output unit 74, the speaker 76, or the vibration generating unit 77, or Combined and output as an answer back (S28a). For example, “cancel release” may be displayed on the display unit 75, notification may be given by voice or melody from the speaker 76, or the vibration generation unit 77 may generate a predetermined type of vibration. When the answer back is finished, the standby state is entered and the unlocking operation is finished. In addition, after the cancellation request signal is transmitted in the process of S12a, an error may be notified when there is no reply even after waiting for a predetermined time from the vehicle.

  As described above, according to the present embodiment, the answerback operation for notifying the completion notification of the locking or unlocking of the vehicle 10 is performed by the mobile phone 70, so that the neighborhood is disturbed by the lamp lighting or the sound of the horn. Can be prevented. Further, if answerback is performed using the display unit 75 or the speaker 76 of the mobile phone 70, the user can clearly confirm whether the lock or unlock has been performed. Furthermore, if the answerback is performed by the vibration generating unit 77, the user can accurately check even when the mobile phone 70 is stored in a pocket or the like.

  Further, the mobile phone 70 is generally equipped with a rechargeable battery and has a large capacity, so that it can be output relatively far away. Further, since the user frequently charges, unlike a conventional type smart key, the user can lock and unlock with relatively high output. Note that a small battery mounted on a general smart key (electronic key) is preliminarily mounted in preparation for a case where the charging battery of the mobile phone 70 has been consumed, and the output of the rechargeable battery decreases. In such a case, if the small battery is controlled so as to execute only a function as a general smart key, it is possible to prevent the user from being locked and unlocked due to the battery running out.

<Second Embodiment>
In the present embodiment, based on the first embodiment, by using the function of the navigation system mounted on the vehicle 10 together, the answer at the time of locking and unlocking according to the position where the vehicle 10 is stopped Change the back method. Here, when the stop position of the vehicle 10 is around the hospital, for example, within 50 m from the hospital, an answer back is made with the mobile phone 70, and when it exceeds 50 m, the vehicle 10 is made answer back. .

  FIG. 5 is a functional block diagram showing a schematic configuration of the wireless lock device 120 according to the present embodiment. Since this configuration is similar to the configuration of the wireless lock device 20 of the first embodiment, components having the same function are denoted by the same reference numerals, description thereof is omitted, and different points will be mainly described. Since the mobile phone 70 can be realized with the same configuration as that of the first embodiment, illustration and description thereof are omitted.

  The answer back control unit 40 of the wireless lock device 120 according to the present embodiment includes a position information specifying unit 42 as illustrated. Then, when the vehicle 10 stops, the position information specifying unit 42 acquires the position where the vehicle 10 stops from the navigation system 60 and whether or not a specific facility, in this case, a hospital is within 50 m around the position. When the hospital is within 50 m from the vehicle 10, the answer back using the direction indicator lamp 23 and the horn 25 of the vehicle 10 is not performed and only the notification to the mobile phone 70 is performed. In this case, the notification of the mobile phone 70 may be notified together with the fact that “a hospital exists in the vicinity”. The mobile phone 70 that has received the notification displays that fact on the display unit 75.

  As a modification of the present embodiment, position information (facility information) of a DSRC (Dedicated Short Range Communication) system may be used. Services using the DSRC system include ETC (Electronic Toll Collection System), parking service, and on-site management in the transportation industry. For example, when a vehicle enters the premises for loading and unloading of luggage, there are times when the premises are noisy and the user cannot grasp even if an answer back is performed on the vehicle side. Therefore, when a vehicle enters a predetermined premises in the DSRC system, the user can be surely grasped by notifying the user's mobile phone of the result of locking and unlocking.

  As described above, according to the present embodiment, it is possible to select whether the answerback for locking and unlocking is performed on the vehicle 10 side or the mobile phone 70 side according to the position where the vehicle 10 is stopped. As a result, it is possible to select an answerback method appropriate for the position where the vehicle is stopped.

<Third Embodiment>
In the present embodiment, the answer back method is changed according to the location of the mobile phone 70 based on the location information used by the mobile phone 70 based on the first embodiment.

  FIG. 6 is a functional block diagram showing a schematic configuration of the mobile phone 170 according to the present embodiment. Since the configuration of the mobile phone 170 is the same as that of the first embodiment, the same functions are denoted by the same reference numerals and the description thereof is omitted. In addition, since the configuration of the wireless lock device 20 of the vehicle 10 can be realized by the configuration of the first embodiment, illustration and description thereof are omitted.

  In the configuration of the mobile phone 170, a configuration different from the configuration of the mobile phone 70 of the first embodiment will be described. First, the mobile phone function unit 72 includes a mobile location information specifying unit 78 and a facility determination unit 79.

  The mobile location information specifying unit 78 uses, for example, a GPS positioning method based on GPS (Global Positioning System) included in the mobile phone 70 or a multiple base station positioning method calculated from a plurality of base station information (synchronization signals) to be connected. The position of is calculated. For this calculation, for example, a known technique applied to an emergency call position notification system or the like can be used.

  The facility determination unit 79 has a predetermined facility (here, a hospital) in the vicinity (here, within 50 m) of the mobile phone 70 based on the position of the mobile phone 70 calculated by the mobile location information specifying unit 78 and the map information. It is determined whether or not. The map information may be stored in advance by the facility determination unit 79 and downloaded from a predetermined server through a mobile phone communication network as necessary. Moreover, the structure which a user can register may be sufficient. Furthermore, the above determination may be made in advance at predetermined time intervals even when the vehicle 10 is not locked and unlocked. In the following, description will be made on the assumption that the locking and unlocking operations are not performed, and the processing time during the locking and unlocking operations will be shortened.

  On the other hand, the electronic key function unit 80 includes a request answerback selection unit 85 that selects the type of answerback requested from the vehicle 10 (wireless lock device 20). This changes the type of answerback to be requested according to the presence / absence of a predetermined facility acquired from the facility determination unit 79 when the user operates the mobile phone 70 to lock and unlock the vehicle 10. .

  The operation of locking and unlocking the vehicle 10 configured as described above will be described based on the sequence diagram of FIG. In this embodiment, as in the first embodiment, the locking and unlocking operations are performed by substantially the same control. Therefore, the unlocking operation will be described here, and the locking operation will be omitted. It should be noted that “a” is attached to the operation of the mobile phone 170 and “b” is attached to the operation of the vehicle 10 in the notation of the symbols indicating each step.

  First, when the user operates the electronic key operation unit 84 of the mobile phone 170 to make an unlock request to the wireless lock device 20 of the vehicle 10 (S110a), the key control unit 81 instructs the facility determination unit 79. Then, a request is made to notify the request answerback selection unit 85 of the determination result of whether there is a predetermined facility (hospital) in the vicinity (S112a).

  Then, the facility determination unit 79 notifies the request answerback selection unit 85 of the determination result, and the facility determination unit 79 specifies the type of answerback according to the determination result (S114a). For example, when there is a hospital in the vicinity, the answer back is performed by the mobile phone 70, and when there is no hospital, the horn of the vehicle 10 is sounded.

  Next, the key control unit 81 wirelessly uses an unlock request signal in which the identified answerback type, the authentication code stored in the ID storage unit 82, and the unlock request are superimposed as a predetermined radio signal. The data is transmitted to the lock device 20 (S116a).

  In the wireless lock device 20, the request acquisition unit 36 of the lock communication unit 34 constantly monitors a radio signal from the mobile phone 70. When the request acquisition unit 36 detects and receives the release request signal (S118b), the request acquisition unit 36 notifies the lock control unit 30 of the type of answerback that is the received content, the authentication code, and the release request (S120b).

  Subsequently, the lock control unit 30 compares the authentication code stored in the authentication storage unit 50 with the received authentication code and determines whether or not they match (S122b). If the two authentication codes do not match (N in S122b), the lock control unit 30 determines that it is an unlocking request for another vehicle and enters the standby state again.

  If the two authentication codes match (Y in S122b), the lock control unit 30 specifies the type of answerback from the information acquired from the mobile phone 70 (S124b), and then drives the lock mechanism 22 to solve it. Lock (S126b).

  When unlocking is completed in the process of S126b, when the vehicle 10 performs answerback (Y in S128b), the answerback control unit 40 turns on the direction indicator lamp 23 with respect to the hazard control unit 24 and the horn control unit 26, The direction indicator lamp 23 and the horn 25 are instructed to level the horn 25, and the direction indicator lamp 23 and the horn 25 are operated as an answer back based on the instruction (S130b). When answerback is performed by the mobile phone 170 (N in S128b), the answerback control unit 40 instructs the notification unit 38 to notify the mobile phone 170 that unlocking is complete, and notifies The unit 38 receives the instruction and outputs an unlocking completion signal in which the authentication code in the authentication storage unit 50 and the unlocking completion are superimposed to the mobile phone 170 (S132b).

  On the other hand, when the electronic key communication unit 83 of the mobile phone 70 outputs the unlock request signal in the process of S116a, if the answerback is not performed by the mobile phone 170, that is, if it is performed by the vehicle 10 (N of S134a). ), The process for unlocking is terminated and the apparatus enters a standby state.

  When answerback is performed by the mobile phone 170 (Y in S134a), the key control unit 81 waits for the unlocking completion signal transmitted from the vehicle 10, and the electronic key communication unit 83 receives the unlocking completion signal. Then (S136a), the authentication code included in the unlocking completion signal is compared with the authentication code in the ID storage unit 82, and it is determined whether or not these authentication codes match (S138a).

  If the authentication codes do not match (N in S138a), the mobile phone 170 (electronic key function unit 80) determines that it is not a release completion signal for the target vehicle, and receives the release completion signal for this mobile phone 170. wait. If there is no release signal for a certain period, the key control unit 81 may display that on the display unit 75, for example.

  When the authentication codes match (Y in S138a), the key control unit 81 determines that the unlocking completion notification has been received from the vehicle 10, and one of the display unit 75, the speaker 76, the vibration generation unit 77 of the output unit 74, or those Is output as an answer back (S140a). When the answer back is finished, the standby state is entered and the unlocking operation is finished. After the cancellation request signal is transmitted in the process of S116a, if there is no reply from the vehicle 10 for a predetermined time, an error may be notified from the output unit 74.

  As described above, according to the present embodiment, the same effects as those of the second embodiment can be obtained, and even when the navigation system 60 of the vehicle 10 cannot be interlocked with the answer back selection process, the configuration on the mobile phone 170 side is sufficient. The answer back selection process can be performed.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to each of those components and combinations thereof, and such modifications are also within the scope of the present invention.

  For example, in the second and third embodiments, the answer back mode is changed according to the position information, but may be changed according to the time zone. In the third embodiment, the key control unit 81 of the mobile phone 170 specifies the time by referring to the clock 90 and performs answerback on the vehicle 10 side or the mobile phone 70 side according to the time zone. It may be determined whether to answer back.

  Further, the authentication code in the mobile phones 70 and 170 may be transferred to another mobile phone by infrared communication, for example. At this time, an expiration date may be set for the transferred authentication code, the number of times of use may be limited, or the use may be limited to only locking and unlocking. That is, the original authentication code may permit all functions as an electronic key, and the copied authentication code may limit the function, the expiration date, and the like. Further, transfer of the authentication codes of the mobile phones 70 and 170 to another mobile phone is limited to only facilities where the authentication code is appropriately managed such as an authorized store, thereby ensuring security. it can.
