Description

  The present invention relates to a building electric lock control system.

  2. Description of the Related Art Conventionally, a system (so-called electronic key system) that uses an electronic key having a wireless function and locks and unlocks a door only by a user holding the electronic key approaching the door of an automobile has been put into practical use. In this electronic key system, when the electronic key approaches the automobile, an ID code (identification information) is transmitted to the in-vehicle controller by a communication circuit built in the electronic key. Then, the in-vehicle controller authenticates the ID code, and the vehicle door is unlocked on the condition that the ID code is correct.

  The electronic key system as described above has been proposed to be applied to a building such as a house, and when the user who possesses the electronic key approaches the entrance door, the entrance door is automatically locked and unlocked. ing. Various techniques for sharing an electronic key between an automobile and a building have also been proposed (see, for example, Patent Document 1). When the electronic key is shared between the car and the building, an authentication device is provided on each of the car side and the building side, and wireless information is exchanged with the electronic key in each of the car side and building side authentication devices. Authentication of the ID code included in the wireless information is performed. In such a case, since the number of keys can be reduced, convenience when carrying or using the electronic key is improved. In addition, management of electronic keys can be simplified.

  However, when the electronic key is shared between the automobile and the building as described above, it is considered that if the automobile is replaced, the electronic key system in the automobile after replacement may not be used as it is on the building side. For example, in the case where the electronic key technology related to automobiles is advanced, if the authentication method differs between the automobile-side authentication device and the building-side authentication device, the electronic key cannot be used in common. Accordingly, system replacement on the building side and the like (replacement of the authentication device, update processing of the authentication algorithm, etc.) is necessary with the replacement of the automobile, and complicated work is required for the user every time the system is replaced. In addition, there is a disadvantage that the cost increases. Depending on the user, it is assumed that the car is frequently replaced, and it is considered that it is practically difficult to replace the system on the building side every time it is replaced.

Although it may be possible to deal with the problem by providing a wide range of authentication methods assuming replacement of cars, technological progress in the future is not an unpredictable and realistic method.

  SUMMARY OF THE INVENTION The main object of the present invention is to provide a building electric lock control system that can share a portable device such as an electronic key with a vehicle and that can suitably cope with a system change accompanying replacement of a vehicle. It is.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary. In the following, in order to facilitate understanding, a corresponding configuration example in the embodiment of the invention is appropriately shown in parentheses, etc., but is not limited to the specific configuration shown in parentheses.

  The building electric lock control system of the present invention includes an electric lock (electric lock 12) provided at an entrance door (entrance door 11), and a building side device (building side controller 13) for locking and unlocking the electric lock. In this system, in accordance with wireless communication with a portable device (electronic key 40) possessed by the user, the lock control of the electric lock is performed by the building side device. . Moreover, the vehicle-mounted apparatus (vehicle side controller 26) mounted in the motor vehicle can communicate with the building side apparatus via a communication means (power lines 18, 31, 62, etc.). Then, when unlocking the electric lock, the identification information (ID code) of the portable device received on the building side is transmitted to the in-vehicle device via the communication means, and authentication based on the identification information is performed in the in-vehicle device. After the authentication, locking / unlocking control of the electric lock is performed on the building side device based on the authentication result of the in-vehicle device.

  According to the above configuration, when unlocking the electric lock provided in the building, the mobile device is authenticated by the in-vehicle device instead of the building-side device. Therefore, even if the building-side device is not replaced after the replacement of the vehicle, the new authentication method can be applied by the new vehicle-mounted device. That is, even after the replacement of a car, building-side locking / unlocking control by a shared portable device can be performed. As described above, in the electric lock control system of the present invention, the portable device such as the electronic key can be shared between the building and the automobile, and the system change associated with the replacement of the automobile can be suitably dealt with.

  The building-side device determines whether or not the identification information received from the portable device is pre-registered identification information when unlocking the electric lock. And if it is the registered identification information, the said building side apparatus itself will perform the authentication, and if it is not registered identification information, it is good to make the authentication of the said identification information be performed by the vehicle-mounted apparatus.

  According to the above configuration, for example, when the identification information of a portable device is changed with replacement of a car, authentication is performed by the building-side apparatus before replacement, and authentication is performed by the in-vehicle apparatus after replacement. Therefore, the electric lock control can be carried out after the replacement of the automobile as in the case before the replacement. In this case, it is not necessary to register new identification information in the building-side device, and a user-friendly system can be realized.

  The building-side device may determine whether or not the automobile that is the communication partner is a registered vehicle registered in advance, and if the building-side device is a registered vehicle, the authentication result by the in-vehicle device may be validated. Thereby, the inconvenience that the electric lock of the building is unlocked illegally using a vehicle that is not a registered vehicle can be avoided.

  In addition, the present invention is applied to a building that is electrically connected to an automobile (automobile 20) having at least one of a power storage function and a power generation function and that exchanges electric power with the automobile. In such a case, it is preferable that communication by the communication unit is enabled in a state where the building and the automobile are electrically connected, and identification information and an authentication result are transmitted and received through the communication unit. According to this configuration, for example, power can be supplied from the automobile side to the building side during a power failure on the building side. Conversely, when the remaining power on the automobile side is reduced (when the battery power is reduced), power can be supplied from the building side to the automobile side. Further, in a state where the building and the automobile are electrically connected, a communication line can be easily opened as a communication means, and identification information and an authentication result can be transmitted and received through the communication line.

  Here, power lines (power lines 18, 31, 62) or dedicated lines connecting buildings and automobiles are used as the communication means, and identification information and authentication results are transmitted and received by wired communication using the power lines or dedicated lines as communication media. And good. In this case, the identification information and the authentication result can be reliably transmitted and received by wired communication. In particular, according to the configuration using the power line as the communication means, the power line for power transmission / reception can also be used as the communication line, and the configuration can be simplified.

  Further, in a system including a power management device (building-side controller 13 or charging device 32) that manages power transfer between a building and a vehicle, the power management device is a registered vehicle registered in advance by a vehicle that is a power transfer partner. It is preferable to open the power line when the vehicle is a registered vehicle. As a result, power supply to other than the registered vehicle can be prevented. In addition, since the identification information and the authentication result cannot be transmitted or received unless the power line is opened, it is possible to avoid the inconvenience that the electric lock of the building is unlocked illegally using a vehicle that is not a registered vehicle.

  In addition, the building-side device may determine whether or not a car that is a power transfer partner is a power transfer target vehicle registered in advance, and if the vehicle is a power transfer target vehicle, the authentication result by the in-vehicle device may be validated. Thereby, the inconvenience that the electric lock of the building is unlocked illegally using a vehicle that is not a power transfer target vehicle can be avoided.

Specifically, a charging device 32 is provided in the garage 30, and AC power of AC 100 V is supplied to the charging device 32 through the power output terminal 19 and the power line 31 on the building 10 side. The automobile 20 is provided with a power terminal 27, while the charging device 32 is provided with a coupling plug 33. Then, when the user inserts the coupling plug 33 into the power terminal 27 of the automobile 20, power is supplied from the charging device 32 to the automobile 20. Thereby, when the power of the vehicle-mounted battery 23 is lowered, the battery is charged by the power supply from the building 10 side.

  However, the electrical connection between the charging device 32 and the automobile 20 is performed when the automobile 20 is parked at a specific position in the garage 30 in addition to the one that requires the user to insert the coupling plug 33 as described above. Alternatively, the charging device 32 and the automobile 20 may be automatically electrically connected. Moreover, the structure provided in the vicinity of the outer wall of the building 10 instead of the garage 30 may be sufficient.

  In the case where the building 10 and the automobile 20 are connected by the power line 31, the power supply may be performed from the automobile 20 side to the building 10 side contrary to the above. Accordingly, for example, emergency power can be supplied to the building 10 at the time of a power failure on the building 10 side.

  The electronic key 40 is a key-type portable device of a size that can be normally carried by the user. The electronic key 40 is a communication for transmitting and receiving various information to and from the building-side controller 13 and the vehicle-side controller 26. A key controller 41 having a function is incorporated. The form of the electronic key 40 is arbitrary, and can be a card type or a wristband type that can be worn on the human body.

  The electronic key 40 is basically an accessory key of the automobile 20 and has a vehicle door lock locking / unlocking operation function, an engine start operation function, and the like. The door 10 of the building 10 can be locked together with the electronic key 40 which is an attached key of the automobile 20.

  Next, the electrical configuration of the electronic key system will be described in detail with reference to FIG.

  As a configuration on the building 10 side, the indoor transceiver 15 includes an indoor antenna unit 51 and a transmission / reception circuit 52 that transmits and receives various signals using the indoor antenna unit 51. More specifically, the indoor antenna unit 51 has a transmission antenna and a reception antenna. The transmission / reception circuit 52 modulates the request signal output from the building-side controller 13 into a radio wave having a predetermined frequency, transmits the request signal from the transmission antenna of the indoor antenna unit 51, and receives the electronic key 40 received by the reception antenna of the indoor antenna unit 51. The ID code signal from is demodulated into a pulse signal and output to the building controller 13. At this time, the request signal is transmitted to a predetermined area around the entrance door 11 on the indoor side. That is, in the predetermined area on the indoor side, the electronic key 40 can receive a request signal.

  The outdoor transceiver 16 includes an outdoor antenna unit 53 and a transmission / reception circuit 54 that transmits and receives various signals using the outdoor antenna unit 53. More specifically, the outdoor antenna unit 53 has a configuration having a transmission antenna and a reception antenna. The transmission / reception circuit 54 modulates the request signal output from the building-side controller 13 into a radio wave having a predetermined frequency and transmits the request signal from the transmission antenna of the outdoor antenna unit 53, and the electronic key 40 received by the reception antenna of the outdoor antenna unit 53. The ID code signal from is demodulated into a pulse signal and output to the building controller 13. At this time, the request signal is transmitted to a predetermined area around the entrance door 11 on the outdoor side. That is, in the predetermined area on the outdoor side, the electronic key 40 can receive a request signal.

  It should be noted that the transmission / reception circuits 52 and 54 may be provided in common in each of the indoor / outdoor transmission / reception devices 15 and 16 separately.

  The building-side controller 13 includes a known microcomputer including a CPU, a ROM, a RAM, and the like. The building-side controller 13 has request information and ID code information (identification information) corresponding to the electronic key 40. Pre-stored. And the building side controller 13 always outputs a request signal to the transmission / reception circuits 52 and 54 of the indoor side transmitter / receiver 15 and the outdoor side transmitter / receiver 16 while the door lock monitoring system is operating. The building-side controller 13 takes in an ID code signal (ID information unique to the electronic key 40) transmitted from the electronic key 40 through the transmission / reception circuits 52 and 54 of the indoor-side transmitter / receiver 15 and the outdoor-side transmitter / receiver 16, and the ID. Authenticate the code signal. Then, the electric lock 12 is locked or unlocked based on the authentication result. However, in the system of the present embodiment, ID authentication is contracted to the automobile 20 side, and whether or not the building-side controller 13 has an ID authentication function is arbitrary (details will be described later).

  Further, a power line communication (PLC) function is added to the building 10, and as a specific configuration, a PLC modem 55 is connected on a wiring connecting the building-side controller 13 and the power line 18. . The PLC modem 55 is a power line communication adapter. The PLC modem 55 superimposes or separates AC power and communication signals.

  On the other hand, as a configuration on the automobile 20 side, the vehicle-side controller 26 includes a known microcomputer including a CPU, a ROM, a RAM, and the like. The vehicle-side controller 26 includes request information and an electronic key 40. Corresponding ID code information (identification information) is stored in advance. The vehicle-side controller 26 has a wireless communication function that enables wireless communication with the electronic key 40, and periodically outputs a request signal from the transmission / reception circuit. Moreover, the vehicle side controller 26 takes in the ID code signal (ID information peculiar to the electronic key 40) transmitted from the electronic key 40, and authenticates the ID code signal. Then, the door lock device 25 is locked or unlocked based on the authentication result.

  The automobile 20 is supplied with AC power via the power line 31, the charging device 32, etc. In the automobile 20, the AC power is converted into DC power by the power converter (AC / DC converter) 61. At the same time, the battery 23 is charged by the DC power.

  Moreover, the power line communication function is added to the automobile 20 as in the building 10, and as a specific configuration, a PLC modem 63 is connected on a wiring connecting the vehicle-side controller 26 and the power line 62. The PLC modem 63 is an adapter for power line communication, and the PLC modem 63 superimposes or separates AC power and communication signals.

  In the electronic key 40, the key controller 41 includes a well-known microcomputer including a CPU, a ROM, a RAM, and the like, and wirelessly enables wireless communication with the building-side controller 13 and the vehicle-side controller 26. Has a communication function. The key controller 41 stores an ID code unique to the electronic key in advance, and the key controller 41 outputs an ID code signal in response to a request (request signal) from the building 10 side or the automobile 20 side. The output ID code signal is transmitted to the outside through a transmission / reception circuit.

  By the way, the automobile 20 is replaced by purchase in several years, for example, and the ID code authentication method may be changed in the automobile 20 after replacement. As the automobile 20 is replaced, the electronic key 40 is also replaced. In this case, if there is a difference between the authentication method on the building 10 side and the authentication method on the automobile 20 side, the lock / unlock control using the common electronic key 40 cannot be performed on the building 10 side. It was forced to change the system. On the other hand, in the present embodiment, when the electric lock 12 is unlocked by the electronic key 40, a configuration in which the ID code authentication on the building 10 side is performed on the automobile 20 side is adopted. The electronic key 40 can be conveniently used.

  In particular, power line communication established between the building-side controller 13 and the vehicle-side controller 26 is used, and an ID code (reception ID from the electronic key 40) is transmitted from the building-side controller 13 to the vehicle-side controller 26 by the power line communication. In response, the vehicle-side controller 26 transmits an authentication result based on the ID code to the building-side controller 13 as a response. And in the building side controller 13, the unlocking process of the electric lock 12 is performed based on the authentication result in the vehicle side controller 26. FIG.

  The unlocking procedure of the electric lock 12 using the electronic key 40 will be described below. Here, a case where the user goes out of the entrance door 11 will be described. It is assumed that the automobile 20 is parked at a predetermined position in the garage 30 and connected to the charging device 32 to enable power line communication with the building 10 side.

  First, when the user approaches the entrance door 11 with the electronic key 40, the electronic key 40 receives a request signal transmitted from the indoor transceiver 15 and the electronic key 40 responds to the request signal with an ID code signal. send. When the building controller 13 confirms the reception of the ID code signal, the ID code signal is transmitted to the vehicle controller 26 by power line communication. The vehicle-side controller 26 authenticates the ID code signal according to a predetermined authentication algorithm. For example, an ID code included in the ID code signal is compared with an ID code registered in advance to determine whether or not they match.

  Thereafter, the authentication result of the ID code signal is transmitted to the building-side controller 13 by power line communication. And in the building side controller 13, the unlocking process of the electric lock 12 is implemented based on an authentication result. At this time, if the authentication is OK (ID code match), the electric lock 12 is unlocked. If the authentication is NG (ID code mismatch), the electric lock 12 is not unlocked.

  Next, a processing procedure of locking / unlocking control executed in this system will be described. FIG. 3 is a flowchart showing the locking / unlocking control processing by the building-side controller 13, and this processing is repeatedly executed by the building-side controller 13 at a predetermined time period.

  In FIG. 3, first, in step S101, it is determined whether or not the current auto lock mode is set. The auto-lock mode is a mode that is enabled by user settings, for example, and automatic locking (automatic locking / unlocking) of the front door 11 is appropriately performed under the mode. If it is not the auto-lock mode, the present process is terminated, and if it is the auto-lock mode, the process proceeds to the subsequent step S102. In step S102, a request signal is output to the indoor transceiver 15 and the outdoor transceiver 16.

  Thereafter, in step S103, it is determined whether an ID code signal responding to the request signal is received from the electronic key 40. If the ID code signal has not been received, the process proceeds to step S106, and if received, the process proceeds to step S104.

  In step S104, it is determined whether or not a communication line using a power line is open between the building 10 and the car 20 side. At this time, as a power line communication opening determination method, for example, it is determined whether or not communication with the vehicle-side controller 26 is possible. More specifically, the vehicle-side controller 26 is configured to output a predetermined weak current signal. If the building-side controller 13 can receive the weak current signal, it is determined that the communication line by the power line is open. In addition, the coupling plug 33 of the charging device 32 is provided with a coupling detection switch that outputs an ON signal (or may be an OFF signal) when coupled to the power terminal 27 on the automobile 20 side, and is based on an output signal from the switch. It is also possible to determine whether to open power line communication.

  Then, if the power line communication is not open, this processing is terminated as it is, and if the power line communication is open, the process proceeds to step S105. In step S105, the ID code signal received from the electronic key 40 is transmitted to the vehicle-side controller 26. As a result, the ID code signal is transmitted to the vehicle-side controller 26 by power line communication.

  Thereafter, in step S106, it is determined whether or not an authentication result in response to the ID code signal has been received from the vehicle-side controller 26, and in subsequent step S107, it is determined whether or not authentication is OK. When both steps S106 and S107 are YES, the process proceeds to step S108, and an unlocking drive signal is output to the electric lock 12. Thereby, the electric lock 12 is unlocked.

  On the other hand, if either of steps S106 and S107 is NO, that is, if the authentication result is not received from the vehicle-side controller 26, or if the received authentication result is not determined to be authentication OK, the electric lock 12 No unlocking drive signal is output. In a state where no unlocking drive signal is output to the electric lock 12, the electric lock 12 is held in a locked state.

  FIG. 4 is a flowchart showing an ID authentication process by the vehicle-side controller 26, and this process is repeatedly executed by the vehicle-side controller 26 at a predetermined time period.

  In FIG. 4, first, in step S201, it is determined whether an ID code signal is received from the building-side controller 13 by power line communication. If the ID code signal has not been received, the present process is terminated. If the ID code signal has been received, the process proceeds to step S202. In step S202, an ID code signal authentication process is executed, and in subsequent step S203, it is determined whether the authentication is OK or NG.

  Thereafter, in step S204, an authentication result (here, a signal representing authentication OK) is transmitted to the building-side controller 13.

  According to the embodiment described above in detail, when the electric lock 12 on the building 10 side is unlocked, the ID authentication of the electronic key 40 is performed by the vehicle-side controller 26 instead of the building-side controller 13. Even if the building-side controller 13 is not replaced after the replacement, the new vehicle-side controller 26 can apply a new authentication method. When the automobile 20 is replaced, it is conceivable that the in-vehicle electronic key technology has become more sophisticated. However, in this case, it is possible to cope without changing the system on the building 10 side. That is, even after the replacement of the automobile 20, the building 10 side locking / unlocking control using the shared electronic key 40 can be performed. As described above, in the electronic key system in which the electronic key 40 is shared between the building 10 and the automobile 20, it is possible to suitably cope with a system change associated with replacement of the automobile 20.

  In addition, since the building 10 and the automobile 20 are connected by the power line 31 and power can be exchanged between them, the battery of the automobile 20 can be charged by supplying power from the building 10 side.

  At this time, the building-side controller 13 and the vehicle-side controller 26 can communicate with each other by power line communication, and ID code information and authentication information are transmitted and received by the power line communication. Etc. can also be used as a communication line, and the configuration can be simplified.

[Second Embodiment]
In the above system, since the vehicle-side controller 26 performs ID authentication, if the building-side controller 13 and the vehicle-side controller 26 are not connected in a communicable state, the electric lock 12 is unlocked and unlocked using the electronic key 40. Control cannot be performed. That is, when the automobile 20 is not parked in a predetermined parking space or when the automobile 20 is used by another user, the lock / unlock control of the electric lock 12 using the electronic key 40 cannot be performed.

  Therefore, as a countermeasure, in the present embodiment, the building-side controller 13 is also provided with an ID authentication function, and basically the building-side controller 13 performs ID authentication. Then, when the building side controller 13 becomes unable to perform ID authentication due to replacement of the automobile 20 or the like, the vehicle side controller 26 performs ID authentication. If the ID code is updated and registered on the car 20 side and ID authentication is impossible on the building-side controller 13 even when the car 20 is not replaced, ID verification is performed on the vehicle-side controller 26 as described above. Is done.

  FIG. 5 is a flowchart showing the locking / unlocking control process in this embodiment, and this process is executed in place of the process in FIG. In FIG. 5, the same steps as those in FIG. 3 are given the same step numbers and the description thereof is simplified. Steps S301 and S302 are additional processing portions.

  In FIG. 5, a request signal is output in the auto lock mode, and reception determination of the ID code signal from the electronic key 40 is performed in that state (steps S101 to S103). Thereafter, in step S301, an ID code signal authentication process is executed, and in the subsequent step S302, it is determined whether the authentication is OK or NG. At this time, it is determined whether or not the ID code received from the electronic key 40 matches the ID code registered in advance in the building-side controller 13. If the authentication is OK, the process proceeds to step S108 and outputs an unlocking drive signal to the electric lock 12. Thereby, the electric lock 12 is unlocked.

  On the other hand, when it determines with it being authentication NG by step S302, it progresses to step S104. Then, as described above, the ID code signal is transmitted to the vehicle-side controller 26 using the power line communication between the building 10 and the automobile 20 (steps S104 and S105). Moreover, the unlocking process of the electric lock 12 is executed based on the authentication result received from the vehicle-side controller 26 (steps S106 to S108).

  As described above, according to the second embodiment, the locking / unlocking control can be suitably performed in the initial state of the system (before the replacement of the automobile 20), and the locking / unlocking control can be performed after the replacement of the automobile 20 as before the replacement. . In this case, it is not necessary to register a new ID code in the building controller 13, and a user-friendly system can be realized.

  Incidentally, when the unlocking operation by the electronic key 40 is impossible, the electric key 12 can be unlocked by inserting and turning the mechanical key of the electronic key 40 into the key hole. The same applies when the battery of the electronic key 40 is dead.

[Other Embodiments]
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  A power management function for managing power exchange between the building 10 and the automobile 20 is added to the building-side controller 13. Then, the building-side controller 13 determines whether or not the automobile 20 that is the partner of power transfer is a registered vehicle (power transfer target vehicle) registered in advance, and the power line 31 is opened when the vehicle is a registered vehicle. May be. As a result, power supply to other than the registered vehicle can be prevented. In addition, since the identification information and the authentication result cannot be transmitted or received unless the power line 31 is opened, there is an inconvenience that the electric lock 12 on the building 10 side is illegally unlocked using the vehicle authentication system that is not a registered vehicle. Can be avoided. In addition, when authenticating a registered vehicle as in this configuration, the registered vehicle is updated in the building-side controller 13 or the like with the replacement of the vehicle 20 (the same applies to the purchase of vehicles).

  The building-side controller 13 may be configured to determine whether or not the automobile 20 that is the partner of power transmission / reception is a registered vehicle registered in advance, and to validate the authentication result by the vehicle-side controller 26 when the vehicle is a registered vehicle. . Even in such a configuration, it is possible to avoid the inconvenience that the electric lock 12 of the building 10 is illegally unlocked by using a vehicle authentication system that is not a registered vehicle.

  A configuration in which electronic keys of a plurality of automobiles can be used may be used. In this case, a plurality of corresponding automobiles are registered in the building-side controller 13 in advance, and the power line 31 is opened when any of the registered vehicles is registered. Alternatively, the authentication result by the vehicle-side controller 26 is validated in the case of any registered vehicle.

  The charging device 32 may be provided with a controller for power management, and the above-described power management function and registered vehicle determination function may be added to the controller.

  When power line communication is performed between the building 10 and the automobile 20, ID code information and authentication information transmitted and received through the power line 31 and the like may be encrypted. Thereby, in the power line 31 etc., ID code information and authentication information are intercepted illegally, and as a result, the inconvenience that the electric lock 12 on the building 10 side is unlocked can be avoided.

  In the said embodiment, although communication between the building side controller 13 and the vehicle side controller 26 was implement | achieved by the power line communication using a power line, this is changed. For example, wired communication means other than power line communication is used. Specifically, a dedicated communication line (dedicated line) is used. Alternatively, wireless communication means is used. In this case, transmission of ID code information from the building 10 to the automobile 20 and transmission of authentication information from the automobile 20 to the building 10 are performed by wired communication means and wireless communication means other than power line communication. In addition, even if the automobile 20 is not parked at a specific position in the garage 30 as described above by enabling wireless communication between the building-side controller 13 and the vehicle-side controller 26 (that is, Communication of ID code information, authentication information, and the like is possible between both controllers (even when electrical connection is not made through a communication medium such as a power line).

  In the said embodiment, although the building side controller 13 was provided as a building side apparatus and this building side controller 13 was set as the structure which has a key authentication function and the lock / unlock control function of the electric lock 12, this structure is changed. For example, a key authentication device is provided separately from the building-side controller 13, the received ID information from the electronic key 40 is authenticated by the key authentication device, and the lock / unlock control of the electric lock is performed by the building-side controller 13. In this configuration, the “building-side device” is configured by the building-side controller 13 and the key authentication device. In this case, communication with the vehicle-side controller 26 may be performed by either the building-side controller 13 or the key authentication device.

  In the above-described embodiment, a hybrid vehicle is used as the automobile 20, but this can be changed to others. For example, an electric vehicle using a motor as a power source is used as the vehicle 20. Alternatively, a vehicle using an engine as a power source is used as the automobile 20. In this case, the vehicle to be applied is arbitrary, but power can be exchanged between the building and the vehicle as long as the vehicle has at least one of the power storage function and the power generation function.
