[Effects of the Invention]

[0007] According to the present invention, a more convenient door management system can be realized by coordinating the door lock operation of a vehicle with the door lock operation of a building. [Brief explanation of the drawing]

[0008] [Figure 1] This figure shows the configuration of a door management system according to one embodiment of the present invention. [Figure 2] This diagram shows the configuration of the vehicle door management system. [Figure 3] This diagram shows the configuration of a building door management system. [Figure 4] This is a flowchart illustrating the processing steps in the door management system. [Modes for carrying out the invention]

[0009] Embodiments of the present invention will be described below with reference to the drawings. Figure 1 shows the configuration of a door management system 1 according to one embodiment of the present invention. The door management system 1 includes a vehicle door management device 3 that manages the locking and unlocking of the vehicle doors of a vehicle 2, and a building door management device 7 that manages the operation of a building door lock mechanism 6 that locks and unlocks the building doors 5 installed in a building 4. The building 4 is, for example, the home of the user 8 of the vehicle 2.

[0010] User 8 unlocks the vehicle door of vehicle 2 using the electronic key 9 of vehicle 2. Furthermore, user 8 can lock and unlock the building door 5 by inserting a building door key (not shown) into the building door lock mechanism 6. User 8 can also lock and unlock the building door 5 by using a mobile terminal 10 owned by user 8 to instruct the building door management device 7 to lock or unlock the building door 5. For example, user 8 can lock or unlock the building door 5 using an application executed on the mobile terminal 10 that sends a signal to the building door management device 7 instructing it to lock or unlock the building door 5.

[0011] The mobile terminal 10 is equipped with, for example, a GPS receiver to determine its current location. In this embodiment, the mobile terminal 10 transmits information about its current location to the vehicle door management device 3 at predetermined time intervals or in response to a request from the vehicle door management device 3.

[0012] Figure 2 shows the configuration of the vehicle door management device 3. The vehicle door management device 3 manages the operation of the vehicle door lock mechanism 11, which locks and unlocks the vehicle doors (not shown) of vehicle 2. The vehicle door lock mechanism 11, for example, locks and unlocks the driver's side vehicle door of vehicle 2.

[0013] The vehicle door management device 3 is also connected to the vehicle door sensor 12. The vehicle door sensor 12 detects the operation of the door handle (not shown) of the vehicle door of vehicle 2 and detects the locked / unlocked state of the vehicle door lock mechanism 11. The vehicle door management device 3 is also connected to the in-vehicle GPS receiver 13.

[0014] The vehicle door management device 3 includes a first processor 20, a first memory 21, and a first communicator 22. The first memory 21 is composed of, for example, a volatile and / or non-volatile semiconductor memory. The first communicator 22 is a transceiver for the vehicle door management device 3 to communicate directly or indirectly via a public line or the like with the building door management device 7, the electronic key 9, and the mobile terminal 10 held by the user 8.

[0015] The first processor 20 is a computer including, for example, a CPU (Central Processing Unit). The first processor 20 may have a configuration including a ROM (Read Only Memory) in which a program is written, a RAM (Random Access Memory) for temporarily storing data, and the like. And the first processor 20 includes, as functional elements or functional units, a vehicle key communication unit 23, a terminal position acquisition unit 24, a vehicle lock control unit 25, a vehicle lock management unit 26, and a vehicle lock detection unit 27.

[0016] These functional elements included in the first processor 20 are realized, for example, by the first processor 20, which is a computer, executing a first management program 28 stored in the first memory 21. The first management program 28 can be stored in any computer-readable storage medium. Instead of this, all or part of the above functional elements included in the first processor 20 may be configured by hardware including one or more electronic circuit components. Here, the first processor 20 corresponds to the first computer in the present disclosure.

[0017] The vehicle key communication unit 23 communicates with the electronic key 9. Specifically, the vehicle key communication unit 23 uses the first communicator 22 to transmit a search signal to the vicinity of the vehicle 2 to search for the electronic key 9 located in the vicinity of the vehicle 2. When the vehicle key communication unit 23 finds the electronic key 9, it communicates with the electronic key 9 using the first communicator 22, receives an authentication code from the electronic key 9, and authenticates the electronic key 9. The vehicle key communication unit 23 also communicates with the electronic key 9 and receives a lock signal from the electronic key 9 to instruct it to lock the vehicle door lock mechanism 11 and an unlock signal to instruct it to unlock. In addition, the vehicle key communication unit 23 detects how far away the electronic key 9 is from the vehicle 2, for example, from the received signal strength of the radio waves transmitted by the electronic key 9 in response to the search signal from the first communicator 22.

[0018] In this embodiment, the vehicle key communication unit 23 communicates with the electronic key 9 only if the vehicle lock management unit 26 has authorized communication with the electronic key 9. That is, the vehicle key communication unit 23 does not communicate with the electronic key 9 if the vehicle lock management unit 26 has not authorized communication with the electronic key 9. Furthermore, when the vehicle lock management unit 26 authorizes the vehicle key communication unit 23 to transmit a search signal to the vicinity of the vehicle 2 via the first communicator 22 to search for the electronic key 9. In other words, when the vehicle lock management unit 26 authorizes the vehicle key communication unit 23 to transmit a search signal, the vehicle key communication unit 23 does not transmit a search signal to search for the electronic key 9.

[0019] The terminal location acquisition unit 24 acquires the current location of the mobile terminal 10 owned by user 8 of vehicle 2. In this embodiment, in particular, if the location of the mobile terminal 10 is more than a predetermined distance away from building 4, which is user 8's home, and vehicle 2, the terminal location acquisition unit 24 sends a user absence notification to the vehicle lock management unit 26. For example, at predetermined time intervals, the terminal location acquisition unit 24 acquires the current location of the mobile terminal 10 and vehicle 2 from the mobile terminal 10 and the in-vehicle GPS receiver 13, and determines whether the location of the mobile terminal 10 is more than a predetermined distance away from building 4, which is user 8's home, and vehicle 2.

[0020] When the vehicle lock control unit 25 receives an unlocking signal and a locking instruction from the vehicle key communication unit 23 from the authenticated electronic key 9, it causes the vehicle door lock mechanism 11 to perform an unlocking operation and a locking operation, respectively. Furthermore, when the vehicle key communication unit 23 has authenticated the electronic key 9 and the vehicle key 9 is detected to be within a few meters of the vehicle 2, and the vehicle door sensor 12 detects that the door handle of the vehicle door has been opened, the vehicle lock control unit 25 causes the vehicle door lock mechanism 11 to perform an unlocking operation.

[0021] Furthermore, the vehicle lock control unit 25 illuminates a welcome light (not shown) located on the underside of the vehicle 2, and / or causes the vehicle door lock mechanism 11 to perform an unlocking operation without waiting for user 8's input, according to the distance from the vehicle 2 to the electronic key 9 detected when the vehicle key communication unit 23 transmits a search signal to the electronic key 9.

[0022] In this embodiment, the vehicle lock control unit 25, in particular, causes the vehicle door lock mechanism 11 to perform a locking / unlocking operation, provided that the vehicle lock management unit 26 has given permission for the vehicle door lock mechanism 11 to perform the locking / unlocking operation.

[0023] The vehicle lock management unit 26 restricts the execution of the unlocking operation of the vehicle door lock mechanism 11 by the vehicle lock control unit 25. In this embodiment, in particular, the vehicle lock management unit 26, in response to the first communication device 22 of the vehicle door management device 3 receiving a building door lock notification from the building door management device 7, authorizes the vehicle lock control unit 25 to perform the unlocking operation of the vehicle door lock mechanism 11. As will be described later, the building door management device 7 transmits a building door lock notification to the vehicle door management device 3 when the building lock detection unit 34 detects that the building door lock mechanism 6 has been locked.

[0024] As a result, in the door management system 1, for example, when user 8 leaves building 4, which is their home, the unlocking operation of the vehicle door lock mechanism of vehicle 2 is permitted only if the building door 5 is locked. This improves the security of vehicle 2 compared to conventional configurations that do not restrict the unlocking operation of the vehicle door lock mechanism. In other words, the door management system 1 improves the security of the locking and unlocking operation of the vehicle door by coordinating with the door lock operation of building 4, which is the home of user 8 of vehicle 2, thereby improving user convenience.

[0025] The vehicle lock management unit 26 also authorizes the vehicle key communication unit 23 to communicate with the electronic key 9 in response to receiving a building door lock notification. As a result, in the door management system 1, for example, communication between the vehicle key communication unit 23 and the electronic key 9 is initiated only when the building door 5 is locked when user 8 leaves the building 4, which is their home. This allows the communication to be limited to cases where user 8 is highly likely to use vehicle 2. Therefore, the door management system 1 can ensure responsiveness of the vehicle door unlocking in response to user operations on the electronic key 9 when user 8 uses vehicle 2, while stopping communication between vehicle 2 and the electronic key 9 when user 8 does not use vehicle 2, thereby suppressing unnecessary power consumption.

[0026] The vehicle lock management unit 26 also, upon receiving a building door lock notification, authorizes the vehicle key communication unit 23 to transmit a search signal to locate the electronic key 9. As a result, the door management system 1 can detect when user 8, who possesses an electronic key 9, approaches vehicle 2 via the vehicle key communication unit 23, only when there is a high probability that user 8 will use vehicle 2, and cause the vehicle lock control unit 25 to illuminate the welcome lights or perform automatic unlocking operations. Therefore, it is possible to suppress unnecessary power consumption in vehicle 2 while maintaining a high level of convenience for user 8.

[0027] The vehicle lock management unit 26 also, in response to receiving a building door lock notification, permits the vehicle lock control unit 25 to perform the unlocking operation of the vehicle door lock mechanism 11. If the vehicle door lock mechanism 11 does not perform the unlocking operation within a predetermined time period, the vehicle lock management unit 26 prohibits the vehicle lock control unit 25 from performing the unlocking operation of the vehicle door lock mechanism 11. As a result of the above operation, the door management system 1 will prohibit the unlocking operation of the vehicle door lock mechanism 11 if there is a high probability that vehicle 2 will not be used, for example, if user 8 does not unlock the vehicle door of vehicle 2 for a predetermined period of time or longer after leaving building 4 and locking the building door 5. In this way, the door management system 1 can improve the security of vehicle 2 in conjunction with the door lock operation of building 4.

[0028] The vehicle lock management unit 26 also prohibits the vehicle lock control unit 25 from performing the unlocking operation of the vehicle door lock mechanism 11 when it receives a user absence notification from the terminal location acquisition unit 24, that is, when the location of the mobile terminal 10 is more than a predetermined distance away from the building 4 which is the user 8's home and the vehicle 2. As a result of the above operation, the door management system 1 will, for example, prohibit the unlocking operation of the vehicle door lock mechanism 11 if user 8 does not intend to use vehicle 2 and the location of user 8's mobile terminal 10 is more than a predetermined distance away from building 4 and vehicle 2. This allows the door management system 1 to further improve the security of vehicle 2.

[0029] The vehicle lock management unit 26 also sends an inquiry message to the mobile terminal 10 asking whether or not to use vehicle 2 when the mobile terminal 10's current location is within a predetermined distance from building 4 or vehicle 2. As a result of the above operation, the door management system 1 can, for example, ask user 8 whether or not to use vehicle 2 when user 8 has left without using vehicle 2 and has returned to the vicinity of building 4. Therefore, based on confirmation of the user's intention, the door management system 1 can start the preparation actions for vehicle use in vehicle 2, thereby improving the convenience of vehicle 2.

[0030] Furthermore, after sending an inquiry message to the mobile terminal 10, if the vehicle lock management unit 26 receives a reply from the mobile terminal 10 indicating that the vehicle 2 will be used, it authorizes the vehicle key communication unit 23 to communicate with the electronic key 9. As a result, the door management system 1 can initiate communication between the vehicle key communication unit 23 and the electronic key 9 as a preparatory action for vehicle use in vehicle 2, based on confirmation of the user 8's intention. This enables smooth boarding of vehicle 2 by user 8 and improves the convenience of vehicle 2.

[0031] The vehicle lock detection unit 27 detects the locking of the vehicle door lock mechanism 11 using the vehicle door sensor 12. In this embodiment, in particular, when the vehicle lock detection unit 27 detects that the vehicle door lock mechanism 11 is locked, it sends a usage completion notification to the building door management device 7. As will be described later, upon receiving the above-mentioned termination of use notification, the building lock management unit 36 ​​of the building door management device 7 authorizes the building lock control unit 35 to perform the unlocking operation of the building door lock mechanism 6. As a result, in the door management system 1, for example, the building door lock mechanism 6 will not be released until user 8 arrives at the building in vehicle 2, and the building door lock mechanism 6 can be released when user 8 gets out of vehicle 2 and locks the vehicle doors. This improves the security of building 4, and also improves convenience for user 8, as they can smoothly enter building 4 after finishing using vehicle 2.

[0032] Alternatively, or in addition to the above, the vehicle lock detection unit 27 may transmit a usage completion notification to the building door management device 7 when it detects that multiple locking instructions have been given to the vehicle door lock mechanism 11. Here, the locking instructions may be, for example, the transmission of a locking signal by an electronic key 9, the operation of a lock switch (not shown) provided on the vehicle door, etc. As a result, user 8 can clearly express their intention to end their use of vehicle 2 by locking the vehicle door lock mechanism 11 through multiple operations that differ from the usual procedure. Therefore, the door management system 1 can reliably reflect this user intention and authorize the unlocking operation of the building door lock mechanism 6.

[0033] Furthermore, when the vehicle lock detection unit 27 detects that the vehicle 2 has arrived within a predetermined distance from the building 4 and that the vehicle door of the vehicle 2 has been opened by the vehicle door sensor 12, it sends a usage completion notification to the building door management device 7. Similarly, in response to receiving the above-mentioned termination notice, the building lock management unit 36 ​​of the building door management device 7 authorizes the building lock control unit 35 to perform the unlocking operation of the building door lock mechanism 6. As a result, in the door management system 1, user 8 can enter building 4 smoothly when they finish using vehicle 2, similar to the above, thus improving convenience for user 8.

[0034] Furthermore, when the vehicle lock detection unit 27 sends a usage termination notification to the building door management device 7, it sends an instruction to the mobile terminal 10 to activate an application for sending an unlock signal to the building door management device 7. As a result, when user 8 finishes using vehicle 2, the door management system 1 can automatically launch an application on user 8's mobile terminal 10 to instruct the unlocking of the building door lock mechanism 6, thereby improving convenience for user 8.

[0035] Figure 3 shows the configuration of the building door management device 7. The building door management device 7 manages the operation of the building door lock mechanism 6, which locks and unlocks the building doors 5 installed in the building 4. The building door management device 7 is connected to the vehicle door management device 3 in a communication manner.

[0036] As described above, user 8 can lock and unlock the building door 5 by inserting the building door key into the building door lock mechanism 6. Furthermore, user 8 can lock and unlock the building door 5 by using a mobile terminal 10 owned by user 8 to instruct the building door management device 7 to lock or unlock the building door 5. For example, user 8 can lock or unlock the building door 5 using an application executed on the mobile terminal 10 that transmits a signal to the building door management device 7 instructing it to lock or unlock the building door 5.

[0037] The building door management device 7 comprises a second processor 30, a second memory 31, and a second communication device 32. The second memory 31 is composed of, for example, a volatile and / or non-volatile semiconductor memory. The second communication device 32 is a transceiver for communicating with the vehicle door management device 3 and the user 8's mobile terminal 10.

[0038] The second processor 30 is, for example, a computer equipped with a CPU. The second processor 30 may also have a configuration that includes a ROM on which a program is written, RAM for temporary data storage, etc. The second processor 30 includes, as functional elements or functional units, a portable key communication unit 33, a building lock detection unit 34, a building lock control unit 35, and a building lock management unit 36.

[0039] These functional elements of the second processor 30 are realized, for example, by the second processor 30, which is a computer, executing a second management program 37 stored in the second memory 31. The second management program 37 can be stored in any storage medium that is readable by a computer. Alternatively, all or part of the above functional elements of the second processor 30 may be configured by hardware, each including one or more electronic circuit components. Here, the second processor 30 corresponds to the second computer in this disclosure.

[0040] The portable key communication unit 33 communicates with the portable terminal 10 held by the user 8 and receives an unlocking signal from the portable terminal 10 instructing the building door lock mechanism 6 to be unlocked.

[0041] The building lock detection unit 34 detects the locked / unlocked state of the building door lock mechanism 6 using a sensor (not shown) provided on the building door lock mechanism 6. In this embodiment, when the building lock detection unit 34 detects that the building door lock mechanism 6 is locked, it transmits a building door locked notification to the vehicle door management device 3 via the second communication device 32.

[0042] In this case, the building lock detection unit 34 may transmit a building door lock notification to the vehicle door management device 3 when it detects that the building door lock mechanism 6 is locked and that user 8 has left the building 4 or when it detects that there is no one inside the building 4. This allows the building lock detection unit 34 to more reliably detect that user 8 has locked the building door lock mechanism 6 when leaving the building 4 and transmit a building door lock notification to the vehicle door management device 3. Note that user 8 being outside the building 4 and the absence of people inside the building 4 can be detected by the building lock detection unit 34 using motion sensors (not shown) placed inside and outside the building 4, respectively, in accordance with conventional technology.

[0043] The building lock control unit 35 controls the locking and unlocking operation of the building door lock mechanism 6. In this embodiment, the building lock control unit 35 executes the unlocking operation of the building door lock mechanism 6 when it has been authorized by the building lock management unit 36 ​​to do so, and when the portable key communication unit 33 receives an unlocking signal from the portable terminal 10. In other words, the building lock control unit 35 does not execute the unlocking operation of the building door lock mechanism 6 when it has not been authorized by the building lock management unit 36 ​​to do so.

[0044] The building lock management unit 36 ​​restricts the execution of the unlocking operation of the building door lock mechanism 6 by the building lock control unit 35. In this embodiment, in particular, the building lock management unit 36 ​​permits the building lock control unit 35 to execute the unlocking operation of the building door lock mechanism 6 when the building door management device 7 receives a usage termination notification from the vehicle door management device 3.

[0045] Furthermore, the building lock management unit 36 ​​authorizes the building lock control unit 35 to perform the unlocking operation of the building door lock mechanism 6 after a predetermined time has elapsed since the building door management device 7 received the termination of use notification. As a result, the door management system 1 can take into account, for example, the time it takes for user 8 to walk from the parking lot of vehicle 2 to the building door 5, and unlock the building door 5 at the moment user 8 arrives at the building door 5.

[0046] Next, the operation procedure of the door management system 1 will be explained. Figure 4 is a flowchart showing the processing procedure in the door management system 1. The process in Figure 4 is executed repeatedly.

[0047] First, the building lock detection unit 34 of the building door management device 7 detects that the building door lock mechanism 6 of building 4 is locked (S100). Also, the vehicle lock management unit 26 of the vehicle door management device 3, in response to the detection result regarding the locking of the building door lock mechanism 6 in step S100, permits the vehicle lock control unit 25 to perform the unlocking operation of the vehicle door lock mechanism 11 under predetermined conditions (S102). As described above, the vehicle lock management unit 26 permits the vehicle lock control unit 25 to perform the unlocking operation of the vehicle door lock mechanism 11, for example, when the first communication device 22 of the vehicle door management device 3 receives a building door lock notification from the building door management device 7.

[0048] Then, the vehicle lock control unit 25 of the vehicle door management device 3 controls the locking and unlocking operation of the vehicle door lock mechanism 11 of the vehicle 2 in accordance with the permission from the vehicle lock management unit 26 in step S102 (S104).

[0049] Here, the process from steps S100 to S104 is executed, for example, when user 8 leaves building 4, which is their home, and begins using vehicle 2.
