Description

  The present invention relates to a technique for controlling unlocking of an object via wireless communication.

  In recent years, smart keys that automatically unlock doors and trunks of vehicles have become widespread. For example, when a user carries a smart key and approaches the vehicle, the door of the vehicle is unlocked. On the other hand, if the smart key is carried away from the vehicle after the door is closed, the door is automatically locked.

  At this time, the key information encrypted from the smart key is transmitted as wireless communication, and the vehicle receives this key information by using an on-board receiver and collates it with previously held key data. If the received key information satisfies a predetermined collation condition, a person who carries the smart key and approaches the vehicle is authenticated as a valid user, and the door or the like is unlocked.

  As a technique for unlocking a door / trunk of a vehicle using such a smart key, for example, in Patent Document 1, an RSSI confirmation command is transmitted from a transmission unit of the vehicle, and the received smart key detects an RSSI value of the command. A technique for returning to a vehicle is disclosed. Here, in the vehicle that has received the RSSI value, the door or the trunk is unlocked if the RSSI value is equal to or greater than a predetermined threshold value.

  Further, in recent years, car sharing in which a specific vehicle is jointly used by registered users is also spreading. Also in this car sharing, key authentication is performed in order to unlock the door of the vehicle. For example, Patent Document 2 discloses a technique for transmitting / receiving reservation information by connecting a mobile terminal to a shared vehicle management server via a network. Here, the booking certificate information received at the mobile terminal is transmitted to the vehicle via Bluetooth (registered trademark), and the vehicle that has received the booking certificate information is collated and authenticated, so that the shared vehicle can be used. Become.

  Further, in Patent Document 3, key information is received from a management center via a mobile phone network and stored in a memory, and similarly, key information is received from the management center via a mobile phone network. And a key authentication system having a vehicle stored in a memory. Here, the key information stored in the wireless communication portable terminal is transmitted to the vehicle via Bluetooth (registered trademark), and the vehicle that has received the key information collates the key information with the stored key information. , Perform the authentication process.

JP 2012-17558 A JP 2009-218942 A JP 2012-43167 A

  However, if the smart key that performs the authentication process as described above is left in the operation area outside the vehicle where wireless communication with the vehicle is possible, the smart key is activated and is in communication with the vehicle. Wireless communication is performed regularly. As a result, there arises a problem that unnecessary power is consumed.

  In fact, it has been reported that as a result of storing the smart key near the garage where the vehicle is parked, the smart key has run out of battery much earlier than planned. In response to this situation, there is an example in which a manual for a smart key to be sold is written to prevent the smart key from being placed near the vehicle for a long time. As a countermeasure, if the wireless communication function of the smart key is turned off, the original advantage of the smart key that the unlocking or unlocking standby can be automatically performed just by approaching the vehicle is lost.

  On the other hand, the situation of using a vehicle that has been reserved and parked at a predetermined place, such as car sharing, is expected to increase more and more in the future. In this case, a situation where the smart key experiences a large number of operating areas outside the vehicle or stays in the area for a long time can be considered sufficiently.

  However, all of the conventional techniques as described above are based on the premise that the wireless communication function is activated for authentication, and are not supposed to cope with the situation in which unnecessary power is consumed.

  The wireless terminal according to the present invention controls the “unlocking unit” to be controlled via wireless communication. This control target includes vehicles (cars) subject to car sharing, private vehicles, and other transportation means, rooms and buildings with doors that can be unlocked at the doorway, and doors that can be unlocked. Various articles and structures such as household electrical appliances and other devices can be applied. In addition, as an unlocking target of the “unlocking portion”, various forms such as a door, a trunk, a door, a shutter, a lid portion, a hatch, and a connection (connector) portion can be adopted.

  Hereinafter, in an embodiment of the present invention that will be described in detail with reference to the drawings, a control target is a vehicle that is a car sharing target, and an unlocking target of the “unlocking unit” is a door of this vehicle.

  FIG. 1 is a schematic diagram for explaining a usage mode of a wireless terminal according to the present invention.

  According to FIG. 1A, first, the user registers in advance the use of the vehicle (control target) 2 that is the object of car sharing. This registration can be performed with respect to the reservation information management server 3 via the network using the smart key terminal 1 which is a wireless terminal. Here, the reservation information management server 3 stores “reservation information” (unlock reservation information) of this user.

Next, the user approaches the vehicle 2 in order to use the vehicle 2 while carrying the smart key terminal 1. Here, the smart key terminal 1
(A) a “wireless communication interface” capable of transmitting a signal for unlocking or unlocking the “unlocking portion” 200 of the vehicle 2;
(B) A “wake-up signal receiving unit” capable of receiving a signal transmitted from the vehicle 2 and including a signal including “identification information” of the vehicle 2. Here, the “wireless communication interface” in (a) is in a stopped state before the “unlocking unit” 200 is controlled.

In addition, the “wake-up signal receiving unit” of (b) is also in a stopped state before the “unlocking unit” 200 is controlled in this embodiment. In this case, the smart key terminal 1
(C) “Acceleration sensor” for measuring the acceleration of the smart key terminal 1
And determining whether or not the smart key terminal 1 is moving based on the measured acceleration information, and activating the “wake-up signal receiving unit” when determining that the smart key terminal 1 is moving. .

  In the usage mode shown in FIG. 1A, since the user is approaching the vehicle 2, the smart key terminal 1 is moving from the acceleration information from the “acceleration sensor” in (c). Is determined. As a result, the “wake-up signal receiving unit” is activated.

  On the other hand, the vehicle 2 periodically transmits an identification signal including “identification information” of the vehicle 2 (for example, every tens to hundreds of milliseconds (milliseconds)). The transmission intensity of this identification signal is set very low. As a result, the wake-up area, which is the area where this identification signal can be received, ranges from several meters to several tens of meters from the vehicle 2, for example. Here, after being activated, the “wake-up signal receiving unit” (smart key terminal 1) that has entered the wake-up area receives the identification signal including the “identification information”.

The smart key terminal 1 further includes
(D) “Reservation information” (unlock reservation information) for using the vehicle 2 is held, and “identification information to be received” from the vehicle 2 is set based on the held “reservation information”. ,
(E) It is determined whether the signal received by the “wake-up signal receiving unit” is a signal including the set “identification information to be received”.

  Here, when it is determined in the determination of (e) that the signal includes “identification information to be received”, the “wireless communication interface” is activated. In FIG. 1A, since the “wake-up signal receiving unit” receives an identification signal including “identification information” from the vehicle 2 that is a user's reservation target, the “wireless communication interface” is activated.

  The vehicle 2 further includes a “target side wireless communication unit” that can establish communication with the “wireless communication interface” of the smart key terminal 1. This “target-side wireless communication unit” transmits a sign signal (beacon) having a predetermined intensity at a predetermined time interval, and receives this sign signal to form an outside vehicle operation area where communication connection is possible. The identification signal including the “identification information” of the vehicle 2 described above may be transmitted from the “target wireless communication unit” or may be transmitted by a separately installed wireless communication unit.

  Here, the “wireless communication interface” (smart key terminal 1) that has entered the outside operation area establishes communication with the “target wireless communication unit” of the vehicle 2 after being activated.

Next, the “wireless communication interface” of the smart key terminal 1 that has established communication in this way receives “authentication information” (unlocking authentication information) from the vehicle 2. Here, the smart key terminal 1
(F) The received “authentication information” and the stored “reservation information” are collated, and when a predetermined collation condition is satisfied, the “unlocking unit” 200 is unlocked or put into an unlocking standby state. An unlocking (standby) signal is transmitted to the vehicle 2 (“target wireless communication unit”) via the “wireless communication interface”.

  When the vehicle 2 receives this unlocking (standby) signal, the vehicle 2 drives the “unlocking part” 200 to unlock the door (door part) 20 or wait for unlocking.

  As described above, the “wireless communication interface” of the smart key terminal 1 is in an initially stopped state and the “identification information” transmitted from the vehicle 2 matches the stored “reservation information”. Only, the “unlock / lock part” 200 is unlocked or a signal for putting it in the unlock standby state is transmitted. That is, since it is activated only when the “unlocking unit” 200 that has been reserved for unlocking is authenticated, it is possible to suppress unnecessary power consumption that does not result in unlocking.

  Further, in the embodiment in which the “wake-up signal receiving unit” is also initially stopped, the “wake-up signal receiving unit” is activated only when it is determined that the smart key terminal 1 is moving. Actually, when trying to unlock the “unlocking part” 200 of the door 20 in the vehicle 2, the user moves to approach the vehicle 2 while carrying the smart key terminal 1. Only when this movement is detected and it is assumed that the user intends to unlock, the “wake-up signal receiver” is activated to further suppress unnecessary power consumption that does not lead to unlocking. can do.

  Incidentally, as an example, the power consumption of the wireless communication unit mounted on the conventional smart key is about 20 μW (microwatt), whereas the power consumption of the wake-up signal receiving unit is about half of that. About 60%. Therefore, it can be understood that the power saving effect by activating not only the “wireless communication interface” but also the “wake-up signal receiving unit” as necessary is sufficiently large. The power consumption of the acceleration sensor is, for example, about 1 μW, and is usually one digit or less smaller than that of the wireless communication unit.

  As described above, according to the smart key terminal 1 of the present invention, the unlocking control after authenticating the “reservation information” can be realized with low power consumption.

  In the determination of (e) above, when it is determined that the signal includes “identification information to be received” and the “wireless communication interface” is activated, the smart key terminal 1 Or “reservation information” to the reservation information management server 3 installed in the network connectable with the smart key terminal 1 using another built-in wireless communication unit, and the reservation information management server 3 It is also preferable to acquire and update “reservation information” for using 2.

  As described above, in the smart key terminal 1, while the user is approaching the vehicle 2, the “reservation information” that is held in advance or updated (in exchange with the server 3) and the received “authentication information”. And the authentication process can be completed. As a result, for example, the user 2 can quickly use the vehicle 2 without causing the inconvenience that the user holds the member card over the vehicle to be car-shared and waits for the authentication to be completed.

  Incidentally, the “wireless communication interface” of the smart key terminal 1 and the “target wireless communication unit” of the vehicle 2 are, for example, a wireless LAN such as Wi-Fi (Wireless Fidelity) or a local such as Bluetooth (registered trademark). A network may be formed.

  In addition, the smart key terminal 1 (“wireless communication interface” or other built-in wireless communication unit) and the reservation information management server 3 include a mobile phone network such as LTE (Long Term Evolution) and 3G (3rd Generation), WiMAX (Worldwide Interoperability for Microwave Access) or a wireless LAN such as Wi-Fi can be connected to the Internet.

  Further, according to FIG. 1B, after unlocking the unlocking portion 200, the user opens the door 20 of the vehicle 2 and arrives at the driver's seat of the vehicle 2. In the vehicle 2, the communication unit of the immobilizer periodically transmits a sign signal (beacon) to form an in-vehicle operation area of the immobilizer. Here, the smart key terminal 1 (the “wireless communication interface”) establishes communication with the communication unit of the immobilizer by entering the vehicle 2 and performs authentication processing, and then starts (standby) the engine. The ID for setting the state is transmitted to the immobilizer.

  The immobilizer that has received the ID for engine start (standby) collates this ID with the engine ECU (Engine Control Unit). The engine ECU starts (standby) the engine if a predetermined collation result is obtained.

  As described above, according to the present embodiment, simply by carrying the smart key terminal 1 and approaching the vehicle 2 and getting into the vehicle, the “reservation information” is collated and the door 20 is unlocked (standby). And the start (standby) of the engine can be performed quickly and automatically while suppressing unnecessary power consumption.

  FIG. 2 is a functional configuration diagram showing an embodiment of a smart key terminal 1 (wireless terminal) and a vehicle 2 (control target) constituting the unlocking control system according to the present invention.

  According to FIG. 2, the unlocking control system includes the vehicle 2 including the unlocking unit 200 and the smart key terminal 1 that controls the unlocking unit 200 of the vehicle 2 via wireless communication. It is also preferable that a reservation information management server 3 installed in a network connectable with the smart key terminal 1 is provided.

[Smart key terminal 1]
The smart key terminal 1 includes a wake-up signal communication unit 100, a wireless communication interface 101, an operation unit 103, and a processor memory. It is also preferable to include an acceleration sensor 102. Here, the processor memory realizes its function by executing a program for causing the computer mounted on the smart key terminal 1 to function.

  Furthermore, the processor memory includes a reservation information management unit 112, an identification information setting unit 113, a wakeup determination unit 114, an interface control unit 115, and a control management unit 116 as functional components. It is also preferable to have a movement determination unit 110 and a wakeup control unit 111 in accordance with the installation of the acceleration sensor 102.

  The wake-up signal communication unit 100 receives an identification signal that is a signal transmitted from the vehicle 2 and includes identification information of the vehicle 2. Further, as will be described later, a wake-up signal for activating the wireless communication interface 202 of the vehicle 2 may be transmitted.

  When the wireless communication interface 101 is activated (by the interface activation unit 115), the wireless communication interface 101 can transmit an unlocking (standby) signal that causes the unlocking unit 200 of the vehicle 2 to be unlocked or put into an unlocking standby state. It is also preferable to receive authentication information from the wireless communication interface 202 after the communication connection / authentication with the wireless communication interface 202 of the vehicle 2 is completed.

  The acceleration sensor 102 is an acceleration measuring unit, and can be a three-axis type acceleration measuring instrument formed by using, for example, a MEMS (Micro Electro Mechanical Systems) technique, for example, by a capacitance method or a piezoresistive method. . As will be described later, it is also preferable to use an acceleration sensor capable of measuring gravitational acceleration and counting the number of steps of the user carrying the smart key terminal 1 as the acceleration sensor 102.

  The operation unit 103 is an input interface such as a push button or a touch panel display. For example, the user can input a reservation for using (unlocking) the vehicle 2 from the operation unit 103. In this case, the input reservation content is registered as reservation information in the reservation information management server 3 via the control management unit 116 and the wireless communication interface 101.

  Further, as will be described later, the operation unit 103 is pressed (or touch-operated) to unlock a door unlocking button (icon that is a request for unlocking the door 20 of the vehicle 2). ) Is also preferable. Furthermore, it is preferable to include a door locking button (icon) that is pressed (or touch-operated) to transmit a door locking request that is a request to lock the door 20. It is also preferable to include a wakeup end button (icon) that is pressed (or touched) to transmit a wakeup end notification to the vehicle 2. Furthermore, it is preferable to include a use end button (icon) that is pressed (or touch-operated) to cause the reservation information management server 3 to transmit a use end notification.

The movement determination unit 110 determines whether or not the smart key terminal 1 is moving from the acceleration information measured by the acceleration sensor 102. As a movement determination method, for example, when the standard deviation of the magnitude of the acceleration value output from the acceleration sensor 102 within a predetermined time is greater than or equal to a predetermined threshold V, it is also determined that the smart key terminal 1 is in a moving state. preferable. Specifically, the three-axis acceleration vector acceleration values output _{a = (a x, a y} , a z) When, its magnitude | a | is
(1) | a | = (a _x ² + a _y ² + a _z ² ) ^0.5
It becomes. The acceleration value, which is k samples detected within the predetermined time T _a , is assumed to be a _i (i = 1, 2,..., K), and the average value of a _i is assumed to be av | a |. (2) (Σ _i (| a _i | −av | a |) ² / k) ^0.5 ≧ V
When the above condition is satisfied, the movement determination unit 110 can determine that the movement state is established. Here, Σ _i is a summation about i.

  As another movement determination method, it is also preferable to use an acceleration sensor 102 capable of measuring the gravitational acceleration and counting the number of steps of the user carrying the smart key terminal 1. In this case, the movement determination unit 110 can determine that the user (smart key terminal 1) is in a moving state when a predetermined number of steps or more are counted.

  The wake-up control unit 111 inputs a determination result from the movement determination unit 110, and activates the wake-up signal communication unit 100 when the input determination result is a true determination (determination that it is in a moving state). Specifically, the power supply unit of the wakeup signal communication unit 100 is turned on.

  The reservation information management unit 112 holds and manages reservation information of the vehicle 2. For example, the reservation information held by the reservation information management unit 112 may refer to the reservation information management server 3 for reservation information, and as a result, a response returned from the reservation information management server 3 may be recorded. Then, it may be updated by the response, or may be created from reservation contents input from the operation unit 103.

  In addition, the reservation information management unit 112 preliminarily stores reservation information for using the vehicle 2 when the wakeup determination unit 114 performs a true determination (determination that a signal including identification information to be received has been received). It is also preferable that the reservation information management server 3 that has registered is inquired about the reservation information, and the reservation information of the vehicle 2 is acquired from the reservation information management server 3 and updated.

Furthermore, as will be described later, when the wakeup signal communication unit 100 receives a signal including the vehicle 2 identification information and the classification information of the vehicle 2 as the wakeup signal, the reservation information management unit 112 holds the reservation information held. On the basis of the identifier (e.g., SSID) of the vehicle 2 corresponding to the received classification information,
(A) When the set identifier matches the identifier included in the beacon signal (beacon) received by the activated wireless communication interface 101, or (b) Connection including the set identifier as a connection destination When the wireless communication interface 101 receives a response signal (for example, a probe response) that is an inquiry signal (for example, a probe request) and corresponds to a connection inquiry signal transmitted from the wireless communication interface 101,
The reservation information management unit 112 causes the wireless communication interface 101 to establish communication with the vehicle 2.

  The identification information setting unit 113 sets identification information to be received from the vehicle 2 based on the held reservation information. The set identification information to be received is output to the wakeup determination unit 114 and used for the wakeup determination.

  The wakeup determination unit 114 determines whether the signal received by the wakeup signal communication unit 100 is a signal including the set identification information to be received. The determination result is output to the interface control unit 115. Further, it is preferable to output the determination result to the reservation information management unit 112.

  The interface control unit 115 activates the wireless communication interface 101 when the determination input from the wakeup determination unit 114 is a true determination (determination that a signal including identification information to be received has been received). Specifically, the power supply unit of the wireless communication interface 101 is turned on. As will be described later, when the wakeup determination unit 114 determines that a signal including information that the door 20 of the vehicle 2 is closed is received, the interface control unit 115 performs wireless communication. It is also preferable to activate the interface 101 and transmit a signal for locking the unlocking unit 200.

  The control management unit 116 includes a communication control unit that controls communication via the wireless communication interface 101, a reservation information verification unit that performs verification / authentication processing using the reservation information managed by the reservation information management unit 112, and the door 20 of the vehicle 2. And an unlocking management unit for grasping the unlocking state and grasping the unlocking state.

  In particular, the control management unit 116 collates the authentication information (unlocking authentication information) received from the vehicle 2 with the reservation information (unlocking reservation information) held or updated in the reservation information management unit 112, When a predetermined verification condition is satisfied, the wireless communication interface 101 is instructed to transmit a signal to unlock the locking / unlocking unit 200 or to enter the unlocking standby state.

  Furthermore, when the control management unit 116 detects that the operation corresponding to the end of use of the vehicle 2 has been performed by the operation unit 103, the control management unit 116 transmits a use end notification to the reservation information management server 3, and sends it to the reservation information management server 3. It is also preferable to register use end information of the vehicle 2 related to the reservation information.

[Vehicle 2]
The vehicle 2 includes a door (door part) 20, an unlocking / locking part 200, a wireless communication interface 202, and a processor memory.

It is also preferable to have an interface control unit 212 in accordance with the installation of the wakeup signal communication unit 201.

  The unlocking unit 200 unlocks the door 20 when the unlocking instruction signal is input from the control management unit 211, and locks the door 20 when the unlocking instruction signal is input. In addition, when the unlocking unit 200 receives an unlocking standby (standby) instruction signal from the control management unit 211, the door unlocks when a predetermined operation (such as pressing a door button or touching a door knob) is performed by the user. It is also preferable to take an unlocking standby (standby) state, which is a standby / monitoring state so that 20 is unlocked.

[Reservation information management server 3]
The reservation information management server 3 is a server installed on the Internet 4 connected to an access network connectable to the wireless communication interface 101 of the smart key terminal 1. The reservation information management server 3 receives the reservation content for use (unlocking) of the vehicle 2 from the wireless communication interface 101, and records / registers it as reservation information.

  Further, when the reservation information management server 3 receives a reservation information inquiry request from the smart key terminal 1 (wireless communication interface 101), the reservation information management server 3 uses the registered corresponding reservation information as a reference result as the smart key terminal 1 (wireless communication interface 101). ). The interface that communicates with the reservation information management server 3 is not limited to the wireless communication interface 101. The reservation information management server 3 may communicate via another wireless communication unit included in the smart key terminal 1. For example, the communication between the wireless communication interface 101 and the wireless communication interface 202 of the vehicle 2 is Wi-Fi or Bluetooth (registered trademark), while the communication between the smart key terminal 1 and the reservation information management server 3 is Alternatively, a mobile phone network may be used.

  FIG. 3 is a schematic diagram showing an embodiment of an identification signal transmitted from the vehicle 2.

According to FIG. 3 (A), the identification signal transmitted from the wireless communication interface 202 (or wake-up signal communication unit 201) (FIG. 2) of the vehicle 2 is
(A) predetermined n (n ≧ 1) first to nth frames;
(B) It is composed of a total of (n + 1) series of frames including the (n + 1) th frame following the nth frame. Incidentally, n is a natural number and can be a value between 10 and 20, for example. The frame length of each frame can be set to several tens to several hundreds μs (microseconds), for example.

Here, (a) each of the first to nth frames has a frame length L ₁ , L ₂ ,..., L _n , and a series of frame length permutations L ₁ , L ₂ , ... constitutes a _{L n.} The vehicle / authentication information management unit 210 (FIG. 2) of the vehicle 2 sets the permutations L ₁ , L ₂ ,..., L _n of the frame length to represent the identification information of the vehicle 2, and as a result The first to nth frames are signals including identification information of the vehicle 2. The identification signal may be a signal in a wireless LAN conforming to the IEEE 802.11 series, Bluetooth (registered trademark), or the like, or a signal in a unique signal system.

On the other hand, the wakeup determination unit 114 (FIG. 2) of the smart key terminal 1 receives a predetermined number of permutations nL ₁ , nL ₂ ,..., NL _n as identification information to be received from the identification information setting unit 113. It is input as a criterion. Here, the wakeup determination unit 114 measures the frame length of the received consecutive frames, and sequentially checks whether the frame length L _i matches nL _i sequentially from the frame length L ₁ of the first frame, that is,
(3) L _i = nL _i (i = 1, 2,..., N)
It is determined whether or not the above condition is satisfied.

When the condition (3) is satisfied for one frame, the condition (3) is similarly determined for the frame length of the next frame. On the other hand, when the condition (3) is not satisfied, the process returns to the beginning again, and then the received frame is the first frame, and the frame length L _i (i = 1, 2,..., N) matches nL _i. It is sequentially determined whether or not to do so.

Here, if the first frame is the first frame and the frame length L _i is the expected frame length nL _i from the first frame to the n-th frame, the wake-up determination unit 114 It is determined that the received signal is a wake-up signal including the set identification information to be received. As a result, the wireless communication interface 101 (FIG. 2) is activated.

Further, the (n + 1) th frame in (b) has a frame length L _{n + 1} , and this frame length L _{n + 1} is the classification information of the vehicle 2. For example, the vehicle / authentication information management unit 210
(A) If vehicle 2 belongs to car sharing company A, set frame length L _{n + 1} = a,
(B) If the vehicle 2 belongs to the car sharing company B, set the frame length L _{n + 1} = b (> a),
(C) If the vehicle 2 is owned by the individual C, the frame length L _{n + 1} is set as c (> b).

  When the wakeup determination unit 114 of the smart key terminal 1 determines that the identification signal to be received has been received as a result of measuring the frame lengths of the first to nth frames, the next received frame is the (n + 1) th received frame. The frame is output to the reservation information management unit 112 (FIG. 2).

Here, the reservation information held in the reservation information management unit 112 includes the frame length L _{n + 1} of the (n + 1) frame and the classification information of the vehicle to be used for reservation (for example, the above (a) to (c) A classification table in which the company 2 and the owner type to which the vehicle 2 belongs is associated is included. Furthermore, an identifier set in the vehicle wireless communication unit (for example, the wireless communication interface 202 of the vehicle 2) belonging to the car sharing company that is the use reservation destination is also recorded.

Next, the reservation information management unit 112 presets the identifier of the vehicle 2 corresponding to the classification information (for example, belonging to the company A) of the vehicle 2 to be used and reserved based on such reservation information. For example, when the communication between the wireless communication interface 101 of the smart key terminal 1 and the wireless communication interface 202 of the vehicle 2 is based on a wireless LAN compliant with the IEEE 802.11 series, the frame length L _{n + 1 of} the (n + 1) th frame is Suppose that it is a. In this case, since the frame length L _{n + 1} = a, it is determined that the company A belongs to the vehicle 2. Furthermore, if the SSID (Service Set IDentifier) recorded in the reservation information and the SSID set in the wireless communication interface 202 of the vehicle 2 belonging to the company A is carsharinga, The SSID is set to this carsharinga.

Next, as shown in FIG. 3A, the reservation information management unit 112 also
(A) The set identifier (SSID) is used as an identifier to be included in a beacon signal (beacon) from which the vehicle 2 is a transmission source, and the beacon signal received by the activated wireless communication interface 101 When the included identifier matches,
The wireless communication interface 101 is instructed to establish communication with the vehicle 2 (the wireless communication interface 202). Alternatively, as another form, as shown in FIG.
(B) The wireless communication interface 101 receives a response signal (probe response) corresponding to the connection inquiry signal transmitted from the wireless communication interface 101, which is a connection inquiry signal (for example, a probe request) including the set identifier as a connection destination. When
Communication with the vehicle 2 (the wireless communication interface 202) can be established with respect to the wireless communication interface 101.

  As described above, since the identification signal transmitted from the vehicle 2 includes the identification information of the vehicle 2 to be reserved for use, the wireless communication interface 101 is activated only by processing and determining this signal. Before, it can be judged whether the vehicle 2 is a use reservation object. As a result, unnecessary power consumption by the wireless communication interface 101 can be suppressed as a result.

  When the identification signal transmitted from the vehicle 2 also includes classification information, the identifier of the wireless communication interface 202 of the vehicle 2 to which the wireless communication interface 101 should be connected (communication established) is determined in advance from the acquired classification information. Since setting is possible, the activated wireless communication interface 101 can be more reliably connected to a desired control target (vehicle 2).

The identification signal transmitted from the vehicle 2 is not limited to the above-described form. For example, first, a state of waiting for L ₁ waiting for reception of a frame having a frame length L ₁ is taken, and then when the signal of frame L ₁ is detected among the received signals, the signal of frame L ₂ is received. it is also preferable to adopt L ₂ wait state waiting to be. In other words, when one frame length frame is received in the frame length permutation L ₁ , L ₂ ,..., L _n , the process of waiting for reception of the next frame length frame in this permutation is performed. it is also preferable to sequentially performed from the first frame length L _1. In this case, it is determined in terms of waiting for the last frame length L _n in the permutation, when receiving a signal of the last frame length L _n, a series of frame signal is received is a wake-up signal, and.

  In any case, if only the signal processing related to the frame length is performed, it is possible to determine a wakeup signal including identification information, and as a result, power consumption during wakeup can be significantly suppressed.
