  However, in the smart interlocking door opening control system, the user himself / herself needs to approach the side door and the back door. In addition, the wireless interlocking door opening control system requires a button operation by the user himself / herself. That is, when there is a passenger, the user himself needs some action and is troublesome.

  The present invention has been made paying attention to such problems, and an object thereof is to provide a door opening control system capable of improving convenience.

  The door opening control system that solves the above-described problem is provided with door control means that permits unlocking of the door by an electronic key having the identification information on the condition that the identification information matching the reference identification information on the door side is acquired. In the door opening control system that performs control to open the door in conjunction with the electronic key system provided, when the door control means permits the unlocking of the door by the electronic key, the owner of the electronic key is together with the electronic key The gist of the invention is to specify the position of another mobile terminal registered in the mobile terminal that the user owns and to open the door in which the other mobile terminal approaches.

  According to this configuration, the identification information is transmitted from the electronic key in response to the request signal from the vehicle or the building, or the identification information is transmitted from the electronic key by operating the operation means of the electronic key. If it matches with the reference identification information on the door side, unlocking of the door by the electronic key having the identification information is permitted. At this time, when a passenger carrying another portable terminal registered in the portable terminal of the user who owns the electronic key is in the vicinity of the side door, the side door is automatically opened. Therefore, since the action required in the smart interlocking or wireless interlocking door opening control system is not necessary, the convenience can be improved.

  Although the user himself / herself needs to possess an electronic key, the portable terminal does not necessarily have to be possessed. That is, it is sufficient if the other portable terminal is registered in the portable terminal owned by the user himself / herself and stored at home or the like. This distinguishes ownership from possession.

  The door opening control system includes unlock detection means for detecting that the door permitted to be unlocked by the door control means is unlocked, and the door control means is configured to unlock the door by the unlock detection means. It is good also as opening the door which said another portable terminal adjoins when a lock | rock is detected.

  According to this configuration, when the unlocking of the door is detected, it is possible to know the intention of getting on or entering the room by the user himself / herself. Therefore, when there is a companion, the door can be opened at an appropriate timing. When targeting a vehicle, “passenger” is used synonymously with a companion, and when targeting both a vehicle and a building, a “companion” with a higher concept is used.

  It should be noted that when the door is permitted to be unlocked with the electronic key, the vehicle does not necessarily get on the vehicle. For example, there may be a situation where the user simply stands by near the vehicle. If the side door is opened in the above situation, the user's intention is not met. According to this structure, it is eliminated.

  The door opening control system includes an indirect position acquisition unit that acquires position information of the other mobile terminal from a base station of the other mobile terminal, and the door control unit is acquired by the indirect position acquisition unit. Based on the position information, the position of the other portable terminal may be specified, and a door as a candidate for opening from that position may be selected.

  According to this configuration, if a vehicle or a building that does not have a direct communication function with another mobile terminal has a function capable of acquiring information from the base station, the position of the other mobile terminal is specified. The candidate doors to be opened can be selected from that position.

  Note that selecting a door that is a candidate for opening includes selecting a door that cannot be opened. That is, in addition to selecting the door that is the candidate for opening the door closest to the specified position from among the plurality of doors and opening the door, the distance to another mobile terminal is the threshold value even for the closest door In the case of exceeding, it is included that none of the doors can be opened.

  According to the present invention, convenience can be improved.

The block diagram which shows the structure of a door opening control system. The figure which shows the flowchart of a system content and door opening control.

Hereinafter, an embodiment of the door opening control system will be described.
As shown in FIG. 1, the door opening control system 1 is applied to a vehicle 2 including a side door to be controlled. The vehicle 2 constitutes an electronic key system 4 together with an electronic key 3 that the user possesses as a vehicle key. The electronic key system 4 can perform bidirectional wireless communication between the vehicle 2 and the electronic key 3 and can perform unidirectional wireless communication with the electronic key 3 as a transmission side. For bidirectional wireless communication, LF (low frequency) band radio waves and UHF (ultrahigh frequency) band radio waves are used, and for unidirectional wireless communication, UHF band radio waves are used.

  The electronic key 3 includes an unlock button 34 that instructs unlocking of all doors including the driver's seat door and the side door, in addition to the LF receiver 31, the key controller 32, and the UHF transmitter 33. The LF receiver 31 can receive a request signal transmitted from the vehicle 2 as an LF band radio wave. When receiving the request signal, the LF reception unit 31 generates a reception signal by electrical processing such as demodulating the signal, and outputs the reception signal to the key control unit 32.

  The key control unit 32 includes a nonvolatile key memory 35. The key memory 35 stores an ID (identification) unique to the electronic key 3. This ID corresponds to identification information unique to the electronic key 3. When the reception signal is input from the LF reception unit 31, the key control unit 32 generates an original signal including the ID in order to respond to the request signal, and outputs the original signal to the UHF transmission unit 33. The UHF transmission unit 33 generates a response signal by electrical processing, such as modulating the original signal input from the key control unit 32, and transmits the response signal to the outside of the electronic key 3 as a UHF band radio wave. . That is, the electronic key 3 receives the request signal and transmits a response signal.

  Further, when the unlock button 34 is operated, the key control unit 32 generates an original signal including an operation code for instructing to unlock all doors and the ID, and sends the original signal to the UHF transmission unit 33. Output. The UHF transmission unit 33 generates a wireless signal by electrical processing, such as modulating the original signal input from the key control unit 32, and transmits the wireless signal to the outside of the electronic key 3 as a radio wave in the UHF band. . That is, the electronic key 3 receives the operation of the unlock button 34 and transmits a wireless signal.

  The vehicle 2 includes an LF transmitter 21, a UHF receiver 22, a security ECU (electronic control unit) 23, a touch sensor 24 built in the outside handle of the driver's seat door, and the fact that the driver's seat door is unlocked. An unlocking sensor 25 for detection is provided. Further, the vehicle 2 can communicate with a GPS receiver 26 that receives radio waves from a GPS (global positioning system) satellite and acquires position information of the vehicle 2 and a base station 5 of a smartphone (multifunctional mobile phone). A communication device 27 is provided. Under the control of the security ECU 23, the LF transmitter 21 transmits a request signal to the vicinity of the vehicle 2 (for example, an area within 1 meter from the driver's door). The UHF receiver 22 can receive a response signal and a wireless signal from the electronic key 3.

  The security ECU 23 includes a nonvolatile vehicle memory 28. In the vehicle memory 28, the IDs of a plurality of regular keys that match the vehicle 2 are registered as reference IDs. The reference ID corresponds to reference identification information on the door side. A list of regular key IDs is defined as a key list 28a. The key list 28a includes the ID of the electronic key 3.

  The security ECU 23 transmits a request signal from the LF transmitter 21 in order to monitor the approach of the regular key. When the response signal is received by the UHF receiver 22 as the request signal is transmitted, the security ECU 23 checks the ID included in the signal with the reference ID. When the ID matches, the security ECU 23 permits the unlocking of all doors using the regular key having the ID. The security ECU 23 corresponds to door control means. When door unlocking is permitted, touching the touch sensor 24 actually unlocks all doors.

  In addition, when the wireless signal is received by the UHF receiver 22, the security ECU 23 compares the ID included in the signal with the reference ID. When the ID matches, the security ECU 23 permits the unlocking of all doors with the regular key having the ID. In this case, the security ECU 23 actually receives all instructions by the operation code included in the wireless signal. Unlock.

  By the way, the door opening control system 1 defines a smartphone 6 that the user who owns the electronic key 3 owns with the electronic key 3 and another smartphone 7 registered in the smartphone 6. The smartphone 7 is the property of a passenger who gets on the vehicle 2 together with the user. The phone number, e-mail address, and the like of the smartphone 7 are registered in the address book of the smartphone 6 or dedicated application software.

  The smartphone 7 communicates with the base station 5 and a GPS receiver 72 that receives radio waves from GPS satellites and acquires position information of the smartphone 7 in addition to the terminal control unit 71 that controls the overall control of the smartphone 7. A possible communication function unit 73 is provided. The terminal control unit 71 includes a nonvolatile terminal memory 74. The terminal memory 74 stores terminal information unique to the smartphone 7. Under the control of the terminal control unit 71, the communication function unit 73 transmits terminal information and position information of the smartphone 7 to the base station 5. Each information is received by the communication device 27 of the vehicle 2 via the base station 5 managed by the mobile phone company. Thereby, the security ECU 23 can acquire the position information of the smartphone 7 together with the terminal information. The communication device 27 corresponds to indirect position acquisition means.

  The vehicle memory 28 of the security ECU 23 stores, for each regular key, terminal information of another portable terminal registered in the portable terminal owned by the owner of each regular key together with its own regular key. A list of terminal information is defined as a terminal list 28b. The terminal list 28b is defined for each regular key. The terminal list 28b of the electronic key 3 includes the terminal information of the smartphone 7. The vehicle memory 28 corresponds to storage means.

  When the terminal information and the position information of the portable terminal are acquired by the communication device 27, the security ECU 23 determines whether or not the terminal information is the terminal information included in the terminal list 28b. Based on the position information acquired together with the terminal information, the position of the portable terminal is specified. Specifically, the position of the mobile terminal relative to the position of the vehicle 2 is specified based on both the position information of the vehicle 2 acquired by the GPS receiver 26 and the position information of the mobile terminal acquired by the communication device 27. The security ECU 23 may always monitor the position of the portable terminal. In this example, the security ECU 23 is portable for a certain period only when the door is unlocked with a regular key in order to reduce the control burden. Monitor terminal location. The GPS receiver 26 corresponds to reference position acquisition means, and the communication device 27 corresponds to terminal position acquisition means.

  If the position of the mobile terminal relative to the position of the vehicle 2 is specified on the assumption that the position of each door is determined from the position information of the vehicle 2, the positional relationship between each door and the mobile terminal is determined. As a result, the security ECU 23 selects the door closest to the mobile terminal as the “candidate door to be opened”. Then, the security ECU 23 confirms that the unlocking sensor 25 detects the unlocking of the driver's door when the selected door is a side door and the distance from the side door to the portable terminal is equal to or less than a threshold value. When triggered, the side door that the mobile terminal is in close proximity is automatically opened. The unlock sensor 25 corresponds to an unlock detection means.

Next, the operation of the door opening control system 1 will be described.
As shown in FIG. 2, it is assumed that the driver (user himself) who has the electronic key 3 and the smartphone 6 gets on the vehicle 2 together with the passenger who has the smartphone 7. As a premise, a passenger's smartphone 7 is registered in the user's own smartphone 6. The vehicle 2 stores the terminal information of the smartphone 7 in association with the ID of the electronic key 3.

  When two people get on the vehicle 2, the user who has the electronic key 3 goes to the driver's seat door, and the passenger who has the smartphone 7 goes to the side door. A request signal is transmitted around the vehicle 2, and when the user who owns the electronic key 3 enters an area covered by the request signal, a response signal is transmitted from the electronic key 3 and included in the response signal. When the ID of the electronic key 3 matches the reference ID of the vehicle 2, unlocking of all doors is permitted. When the user touches the touch sensor 24 built in the outside handle of the driver's seat door, all the doors are actually unlocked.

  On the other hand, the terminal information and position information of the smartphone 7 are transmitted from the smartphone 7 possessed by the passenger, and each information is received by the vehicle 2 via the base station 5. As described above, when the unlocking of the door by the electronic key 3 is permitted, the position of the smartphone 7 is specified for the smartphone 7 associated with the electronic key 3. At this time, when the passenger carrying the smartphone 7 is in the vicinity of the side door, the side door is automatically opened when the unlocking of the driver's seat door is detected.

As described above, according to the present embodiment, the following effects can be obtained.
(1) When a passenger who has another smartphone 7 registered in the smartphone 6 of the user who owns the electronic key 3 is in the vicinity of the side door, the side door automatically opens. Therefore, since the action required in the smart interlocking or wireless interlocking door opening control system is not necessary, the convenience can be improved.

  (2) When unlocking of the driver's seat door is detected, it is possible to know the intention of the user to get on. Therefore, when there is a passenger, the side door can be opened at an appropriate timing.

  (3) When unlocking of the door by the electronic key 3 is permitted, it does not necessarily result in a boarding, for example, a situation where the user simply stands up near the vehicle 2 is also conceivable. If the side door is opened in the above situation, the user's intention is not met. According to this structure, it is eliminated.

  (4) Even if the vehicle 2 does not have a direct communication function with the smartphone 7, as long as it has a function (communication device 27) that can acquire information from the base station 5, the position of the smartphone 7 can be specified. From that position, “candidate doors to be opened” can be selected.

  (5) On the assumption that the position of each door is determined from the position information of the vehicle 2, if the position of the smartphone 7 relative to the position of the vehicle 2 is specified, the positional relationship between each door and the smartphone 7 is determined. Therefore, it becomes easy to select “a door to be opened”.

In addition, the said embodiment can also be changed and actualized as follows.
In the above-described embodiment, when the unlocking sensor 25 detects the unlocking of the driver's seat door, the side door to which the smartphone 7 approaches is opened. Instead, when the unlocking of the door by the electronic key 3 is permitted, the smartphone 7 can open the adjacent side door regardless of whether or not the unlocking sensor 25 detects the unlocking of the driver's seat door. It may be.

  According to this configuration, the fact that the unlocking of the door by the electronic key 3 is permitted means that the user who has the electronic key 3 is present in the request signal transmission area, for example. Under such a premise, even if the side door close to the passenger carrying the smartphone 7 is opened, security is ensured. Therefore, both convenience and security can be achieved.

  In the above embodiment, the vehicle 2 includes the communication device 27 as an indirect position acquisition unit that acquires the position information of the smartphone 7 from the base station 5 of the smartphone 7. Instead of this, the vehicle 2 may include a short-range wireless communication device as a direct position acquisition unit that acquires terminal information unique to the smartphone 7 and position information of the smartphone 7 from the smartphone 7. In this case, when the terminal information and the position information of the smartphone 7 are acquired by the short-range wireless communication device, the security ECU 23 determines whether the terminal information is the terminal information included in the terminal list 28b. When the determination is made, the position of the smartphone 7 is specified based on the position information acquired together with the terminal information. Then, from that position, a “door that is a candidate for opening” is selected.

  According to this configuration, the position of the smartphone 7 can be specified based on information directly acquired by the vehicle 2 from the smartphone 7, and “a door to be a candidate for opening” can be selected from the position.

-It may replace with the vehicle 2 and may be actualized in the door opening control system which performs control which opens the door of a building.
-The electronic key 3 is used as a regular key common to both the vehicle 2 and the building, and the position of the smartphone 7 registered in the smartphone 6 owned by the owner of the electronic key 3 together with the electronic key 3 is specified, You may materialize in the door opening control system which opens the door of the vehicle 2 or building where the smart phone 7 adjoins. However, since the effective area expands, it is desirable to accompany the notification function for the user who possesses the electronic key 3, that is, the notification that the smartphone 7 has opened the adjacent door. Instead of notifying that the door has been opened, a confirmation message as to whether or not the door can be opened is notified, and the smartphone 7 can open the adjacent door on the condition that the user's approval has been obtained. Good.

  Further, on the assumption that there are a plurality of mobile terminals registered in the smartphone 6, of which the mobile terminal A is carried by the accompanying person A and the mobile terminal B is held by the accompanying person B, Is close to the door A, and when the companion B is close to the door B, both the door A and the door B may be automatically opened as control targets.

  The door to be controlled is not limited to the side door of the vehicle 2 but may be a back door of the vehicle 2 or a back door of a building. Of the opening / closing bodies such as doors, it is most desirable to control doors that are used to enter or enter the room, and the shutter may be treated as synonymous with the doors. Further, the rear seat door is not normally controlled to automatically open, but may be controlled to automatically open the window glass of the rear seat door. In this case, in addition to the electronic key system 4, a power window system is linked to the door opening control system 1.

Next, a technical idea that can be grasped from the above embodiment and another example will be described.
(A) In the door opening control system, the door control means is provided with an unlock detection means for detecting that the door permitted to be unlocked by the door control means is unlocked, and the door control means permits the door to be unlocked by an electronic key. When the door is unlocked by the unlocking detection means, another portable terminal opens the adjacent door.

  According to this configuration, the fact that the unlocking of the door with the electronic key is permitted means that the electronic key is placed at a position close enough to allow the door control means to obtain identification information that matches the reference identification information on the door side. There will be the user himself / herself. Under such a premise, even if the door close to a companion who has another portable terminal is opened, security is ensured. Therefore, both convenience and security can be achieved.

  (B) In the door opening control system, a storage means for storing a list of terminal information unique to another mobile terminal registered in the mobile terminal owned by the owner of the electronic key together with the electronic key, and another mobile terminal A terminal position unique to the other mobile terminal and direct position acquisition means for acquiring the position information of the other mobile terminal, and the door control means includes the terminal information of the other mobile terminal by the direct position acquisition means. When the position information is acquired, it is determined whether the terminal information is the terminal information included in the list stored in the storage means, and when the determination is affirmative, the position information acquired together with the terminal information is also included. In addition, the position of another mobile terminal is specified, and a door that is a candidate for opening from that position is selected.

  According to this configuration, based on information directly acquired by a vehicle or building from another mobile terminal, the position of the other mobile terminal can be specified, and a door that is a candidate for opening from that position can be selected.

  (C) In the door opening control system, reference position acquisition means for acquiring reference position information indicating the position of the vehicle or building including the door to be controlled, and terminal position information indicating the position of another portable terminal are acquired. A terminal position acquisition means, and the door control means separates the reference position based on both the reference position information acquired by the reference position acquisition means and the terminal position information acquired by the terminal position acquisition means. Identify the location of the mobile terminal and select a door that is a candidate for opening from that location.

  According to this configuration, on the assumption that the position of each door is determined from the reference position information, if the position of another mobile terminal relative to the reference position is specified, the positional relationship between each door and another mobile terminal is determined. Therefore, it becomes easy to select doors that are candidates for opening.
