  With the widespread use of mobile terminals, the number of mobile terminals brought into the vehicle is also increasing. Then, it becomes a problem which mobile terminal and in-vehicle terminal should cooperate. If it is the system which connects a vehicle-mounted terminal and a portable terminal with a wire communication, the portable terminal which should cooperate can be discriminate | determined easily. However, when the connection form between the in-vehicle terminal and the mobile terminal is a wireless system, the in-vehicle terminal cannot determine which mobile terminal should be linked.

  When there are a plurality of devices that can be connected in a wireless LAN, Bluetooth (registered trademark), etc., it is common to display identifiers of these devices in a list format and allow the user to select which device to connect to. Is. However, such an identifier is often a meaningless character string for the user, and it is not easy for the user to know which identifier corresponds to which device.

  In consideration of such a problem, the present invention provides a technology capable of easily determining which mobile terminal to communicate with in an in-vehicle terminal that performs wireless communication with the mobile terminal.

  Since the passenger of the vehicle is seated in the seat, it is convenient if the portable terminal on which the in-vehicle terminal performs wireless communication can be designated by the seat. The present invention has been made based on such an idea, and a means for receiving an identifier of a mobile terminal is provided in the seat, and the seat and the mobile terminal are stored in association with each other, so that the communication partner can be specified by specifying the seat. A portable terminal can be selected.

More specifically, the present invention is an in-vehicle terminal that performs wireless communication with a mobile terminal, a load sensor provided in a seat, and a terminal identifier receiving unit provided in the seat, wherein the load Corresponding to any seat, terminal identifier receiving means for receiving the identifier of the mobile terminal from the mobile terminal when the sensor has a predetermined input or more, storage means for storing the identifier of the mobile terminal and the seat position in association with each other Communication seat selection means for determining whether to perform wireless communication with the attached mobile terminal, and communication means for performing wireless communication with the mobile terminal associated with the seat determined by the communication seat selection means .
In the present invention, it is also preferable that the terminal identifier receiving unit does not receive the identifier of the portable terminal or lengthens the reception interval while an input of a predetermined value or more continues to the load sensor.

In the present invention, it is preferable that the communication seat determination means is configured to be able to determine the communication partner mobile terminal by specifying the seat. For example, a display for prompting the user to select a seat can be performed before starting communication between the in-vehicle terminal and the mobile terminal, and an input of seat selection can be received from the user. In this case, the communication seat determining means determines to perform wireless communication with the mobile terminal associated with the seat selected by the user.

  The communication seat selection means stores the priority for each of the plurality of seats, and performs wireless communication with a mobile terminal associated with the highest priority seat among the mobile terminals stored in the storage means. It is also preferred to configure to do so. The priority may be stored in advance by the in-vehicle terminal as a setting, or may be an input received from the user.

  In the present invention, the terminal identifier receiving means can be a human body communication means for performing human body communication with a portable terminal. The human body communication means is configured to receive an identifier of the mobile terminal from the mobile terminal. Since the human body communication means is associated with the seat, the correspondence between the identifier received by the human body communication means and the seat can be grasped.

In the present invention, the terminal identifier receiving means may be a power supply means for charging the mobile terminal. The power supply means is configured to receive an identifier of the mobile terminal from the mobile terminal when power supply is executed. Since the power supply means is associated with the seat, the correspondence between the identifier received by the power supply means and the seat can be grasped. The power supply may be wireless power supply (wireless power supply means) or wired power supply (wired power supply means). For example, the terminal identifier receiving unit can be a wired power feeding unit that performs wired power feeding via a cigar socket. In this case, the terminal identification receiving means is the portable terminal at the time of power supply by wired connection.
Preferably, the identifier of the portable terminal is received.

  According to such a configuration, the portable terminal with which the in-vehicle terminal performs wireless communication can be specified by the seat. Therefore, for example, when the user designates a seat, the portable terminal owned by the user who is seated in the seat can be selected. Alternatively, by setting a high priority for a specific seat (for example, a driver's seat), it is possible to preferentially select a mobile terminal owned by a user seated in that seat.

  In the present invention, the portable terminal may be any device that can be carried by the user and can perform wireless communication with the in-vehicle terminal. As an example, a mobile phone terminal, a smart phone terminal, a tablet type or a notebook type computer can be cited.

  In the present invention, the wireless communication method between the mobile terminal and the in-vehicle terminal may be any method, and examples thereof include a wireless LAN and Bluetooth (registered trademark). Information may be transmitted in one direction from the in-vehicle terminal to the portable terminal, information may be transmitted in one direction from the portable terminal to the in-vehicle terminal, and information may be transmitted bidirectionally between the in-vehicle terminal and the portable terminal. Also good.

  In addition, this invention can be grasped | ascertained as a vehicle-mounted terminal provided with at least one part of the said means. The present invention can also be understood as a communication method for an in-vehicle terminal that executes at least a part of the above processing. The present invention can also be understood as a computer program for causing a computer to execute this method. Further, the present invention can be understood as a management server or a vehicle that executes at least a part of the above processing. Each of the above means and processes can be combined with each other as much as possible to constitute the present invention.

(First embodiment)
<Configuration>
1st Embodiment of this invention is a cooperation system of a vehicle-mounted terminal and a portable terminal, The content which the portable terminal output with its output device is transmitted to a vehicle-mounted terminal by radio | wireless communication, and the output device of a vehicle-mounted terminal is used. This is an output system. In the present embodiment, even when there are a plurality of portable terminals that can cooperate in a vehicle, the user can easily select a portable terminal that performs cooperation.

  FIG. 1 is a diagram illustrating an overview of a cooperation system according to the present embodiment. The linkage system according to the present embodiment includes a mobile terminal 100, a plurality of sheet sensors 200, and an in-vehicle terminal main body 300.

  The portable terminal 100 may be of any type as long as it is a portable information processing apparatus capable of wireless communication and human body communication. As an example, a mobile phone terminal, a smart phone terminal, a tablet type or a notebook type computer can be cited. The portable terminal 100 includes a terminal identifier storage unit 101, a human body communication unit 102, a content output control unit 103, and an in-vehicle terminal cooperation unit 104 as functional units. These functional units are realized by an arithmetic device (CPU or the like) included in the mobile terminal 100 executing a software program in cooperation with a storage device or other peripheral devices. However, some or all of the functional units may be realized by a dedicated hardware circuit. In addition to the functional units shown here, the mobile terminal 100 also has functions that the information processing apparatus generally has. For example, an image output device such as a liquid crystal display, an audio output device that outputs sound, an input device such as a keyboard and buttons, a touch screen, and a microphone for receiving input from a user, an external network via a wireless LAN or a mobile communication network A communication device for accessing the network.

  The terminal identifier storage unit 101 stores an identifier (ID) unique to the mobile terminal 100. The human body communication unit 102 performs human body communication with the human body communication unit 201 of the sheet sensor 200 and transmits the identifier stored in the terminal identifier storage unit 101 to the sheet sensor 200. Any known system can be adopted as the system for human body communication. In the present embodiment, electric field type human body communication utilizing changes in the surface electric field of the human body is employed. FIG. 2 is a diagram schematically illustrating communication by human body communication. The human body surface electric field is changed by applying a voltage to the human body from the human body communication unit 102 of the portable terminal 100. The human body communication unit 201 of the sheet sensor 200 incorporates a photonic electric field sensor, thereby amplifying a change in the surface electric field of the human body and reading a signal. Accordingly, if the user sits in the seat with the portable terminal 100 owned, the identifier of the portable terminal 100 is transmitted to the seat sensor 200.

The content output control unit 103 is a functional unit that controls output of content such as images, moving images, and music (sound). The contents to be output and the acquisition method are not particularly limited in the present invention. For example, content stored in the storage device of the mobile terminal 100 may be output, or content may be acquired and output from the outside via the Internet or a mobile phone network.

  The content output control unit 103 switches between control for outputting content to the output device (display device or audio output device) of the mobile terminal 100 and control for outputting to the output device of the in-vehicle terminal 300 via the in-vehicle terminal cooperation unit 104. Configured to be possible. For example, the output destination can be switched based on an instruction from the in-vehicle terminal cooperation unit 104.

  The in-vehicle terminal cooperation unit 104 is a functional unit that performs wireless communication with the mobile terminal cooperation unit 304 of the in-vehicle terminal 300 and performs cooperation for outputting the output from the content output control unit 103 by the in-vehicle terminal 300. The wireless communication method is not particularly limited, and any method can be adopted. Note that a control method for outputting the output of the mobile terminal 100 to the output device of the in-vehicle terminal 300 is described in Patent Document 1 (Japanese Patent Laid-Open No. 2003-244343) and the like, and the detailed description thereof is described in this specification. I will omit it.

  The seat sensor 200 is provided in a seat in the vehicle. Although it is preferable that the seat sensors 200 are provided in all seats in the vehicle, in the present embodiment, the seat sensors 200 may be provided in a plurality of seats in the vehicle, and the seat sensors 200 are not provided. May be present. The sheet sensor 200 includes a human body communication unit 201 and a portable terminal identifier notification unit 202.

  As described above, the human body communication unit 201 of the sheet sensor 200 can communicate with the human body communication unit 102 of the mobile terminal 100. The sheet sensor 200 receives the identifier of the mobile terminal 100 via the human body communication unit 201 and the human body communication unit 102. The human body communication unit 102 of the sheet sensor 200 corresponds to a terminal identifier receiving unit in the present invention. It is preferable that the human body communication unit 201 of the seat sensor 200 communicates with the human body communication unit 102 of the mobile terminal 100 at a predetermined interval to confirm that the user having the mobile terminal 100 is seated in the seat.

  The mobile terminal identifier notification unit 202 notifies the mobile terminal position specifying unit 301 of the in-vehicle terminal 300 of the identifier received by the sheet sensor 200. Communication between the seat sensor 200 and the in-vehicle terminal 300 is sufficient if it is performed by wired communication, but wireless communication may be employed. Here, by configuring each sheet sensor 200 to use a communication path different from that of the mobile terminal position specifying unit 301, it is possible to determine from which sheet sensor the identifier is transmitted. Alternatively, when each seat sensor is configured to use a common communication path, it is transmitted from which seat sensor by adding the identifier of the seat sensor 200 (seat) to the terminal identifier of the mobile terminal 100 and transmitting the same. It is possible to determine whether it is an identifier.

  The sheet sensor 200 may include functional units other than those described above. For example, it is preferable to provide a load sensor so that it can be detected that the user is seated in the seat. In this case, for example, the sheet sensor 200 can be operated only when the load sensor has a predetermined input or more. Alternatively, it is also preferable to transmit the terminal identifier to the in-vehicle terminal 300 only when the load sensor has a predetermined input or more and the human body communication unit 201 receives the terminal identifier. By doing in this way, it can suppress acquiring the identifier of the portable terminal 100 which is directly placed in the seat, and the portable terminal 100 which the user who is not seated in the seat has. In addition, since it can be determined that the user continues to be seated when an input of a predetermined value or more is continuously input to the load sensor, it is possible to omit the acquisition of the identifier again through human body communication or increase the identifier acquisition interval during that time. You can also do it.

The in-vehicle terminal 300 includes a mobile terminal position specifying unit 301, a mobile terminal position storage unit 302, a cooperative seat selection unit 303, a mobile terminal cooperation unit 304, and an output unit 305. These functional units are realized when an arithmetic device (CPU or the like) included in the in-vehicle terminal 300 executes a software program in cooperation with a storage device or other peripheral devices. However, some or all of the functional units may be realized by a dedicated hardware circuit. In addition, the in-vehicle terminal 300 has functions that the in-vehicle device generally has in addition to the functional units shown here. For example, an image output device such as a liquid crystal display, an audio output device that outputs sound, an input device such as a keyboard, buttons, a touch screen, and a microphone for receiving input from a user are provided. The in-vehicle terminal 300 may include a functional unit such as a GPS device, a map information database, or a route search unit. Moreover, you may provide the communication apparatus for accessing an external network via wireless LAN or a mobile communication network.

  The mobile terminal position specifying unit 301 receives the identifier of the mobile terminal 100 from the seat sensor 200 (mobile terminal identifier notifying unit 202), and specifies the mobile terminal possessed by the user seated in the seat for each seat. As described above, the correspondence between the seat and the portable terminal is acquired through which communication path the identifier of the portable terminal is input, or the identifier of the seat sensor 200 (seat) input together with the identifier of the portable terminal. Can be done.

  The correspondence between the seat specified by the mobile terminal location specifying unit 301 and the mobile terminal is stored in the mobile terminal location storage unit 302. The portable terminal position storage unit 302 corresponds to the storage unit in the present invention. FIG. 3 is a diagram illustrating an example of a table included in the mobile terminal position storage unit 302. As illustrated in FIG. 3, the portable terminal position storage unit 302 stores, for each seat, an identifier of the portable terminal 100 corresponding to the seat. Here, for a seat to which the identifier of the mobile terminal is not transmitted from the seat sensor (that is, a seat where a user having a mobile terminal is not seated), the terminal identifier column remains blank.

  The cooperation seat selection unit 303 determines which mobile terminal 100 the in-vehicle terminal 300 is to cooperate with. Here, the linked seat selection unit 303 performs selection based on the seat. That is, it is determined which wireless communication is performed with the portable terminal associated with which seat. The linked seat selection unit 303 corresponds to communication seat selection means in the present invention.

  In this embodiment, prior to the start of cooperation with the mobile terminal 100, the user is inquired about which seat of the mobile terminal is to be linked and input from the user. It is determined that the mobile terminal associated with the assigned seat is to be linked. For example, as shown in FIG. 4, the cooperative seat selection unit 303 performs a display for prompting the user to select a seat on the output unit 305, and receives the seat selection from the user as an input. In the display example shown in FIG. 4, it is assumed that a user having a mobile terminal is not seated in the right rear seat 43, and therefore the right rear seat is displayed in a non-selectable state, and other seats are displayed. Displayed in a selectable state. In the display example of FIG. 4, the driver's seat 41 is selected as the seat position of the mobile terminal that cooperates with the in-vehicle terminal. The linked seat selection unit 303 acquires the identifier of the mobile terminal associated with the selected seat from the mobile terminal location storage unit 302 and sends the acquired identifier to the mobile terminal link unit 304.

  The portable terminal cooperation unit 304 is a functional unit for performing cooperation by performing wireless communication between the in-vehicle terminal 300 and the portable terminal 100. The portable terminal cooperation unit 304 corresponds to a communication unit in the present invention. The mobile terminal cooperation unit 304 performs cooperation processing with the mobile terminal 100 having the identifier notified from the cooperation seat selection unit 303. In the present embodiment, a content output is received from the in-vehicle terminal 300, and this content is displayed or reproduced by the output unit 305. The output unit 305 includes an image output device that displays an image and an audio output device that reproduces sound. At the time of display on the output unit 305, it is also possible to perform resolution conversion or display by adding an operation button. Since these details are described in Patent Document 1, description thereof is omitted in this specification.

(Operation example)
With reference to the flowchart shown in FIG. 5, the overall processing flow of the cooperation system according to the present embodiment will be described according to a specific example.

  When a user having the mobile terminal 100 sits in a seat in the vehicle, human body communication is performed between the human body communication unit 102 of the mobile terminal 100 and the human body communication unit 201 of the seat sensor 200, and the identifier of the mobile terminal 100 is the mobile terminal. 100 is transmitted to the sheet sensor 200 (S50, S51). The mobile terminal identifier notification unit 202 of the sheet sensor 200 notifies the in-vehicle terminal 300 of the acquired identifier of the mobile terminal 100. The portable terminal position specifying unit 301 of the in-vehicle terminal 300 can grasp the correspondence between the seat and the portable terminal (identifier) by checking which seat sensor the identifier is received from. The data is stored in the position storage unit 302 (S52). This process is performed for each seat provided with the seat sensor 200, and is performed periodically. Therefore, the correspondence relationship between the seat and the mobile terminal is kept up-to-date.

  The cooperation process between the in-vehicle terminal 300 and the portable terminal 100 is started based on an explicit instruction from the user, for example. In this case, the user operates the in-vehicle terminal 300 and inputs an instruction to start cooperation (S53). In response to this instruction, the cooperative seat selection unit 303 of the in-vehicle terminal 300 displays a message prompting the user to select a seat (S54). As shown in FIG. 4, an input screen on which a user having a mobile terminal can select a seating seat is presented. The user looks at this screen and selects which mobile terminal content (moving image or the like) is to be output by the output unit 305 of the in-vehicle terminal 300 by selecting a seat (S55). Since it is possible to select by seat, it is possible to select “output the mobile terminal output of the driver (user seated in the driver's seat) to the in-vehicle terminal” without being aware of the identifier of the mobile terminal itself. It becomes.

  The seat selected by the user is sent to the linked seat selection unit 303 of the in-vehicle terminal 300, and the linked seat selection unit 303 refers to the portable terminal position storage unit 302 and acquires the identifier of the portable terminal associated with the seat. (S56). Thereby, the portable terminal 100 which should cooperate with the vehicle-mounted terminal 300 can be specified. And the notification to start cooperation is sent from the portable terminal cooperation part 304 of the vehicle-mounted terminal 300 to the vehicle-mounted terminal cooperation part 104 of a portable terminal, and cooperation between terminals is started (S57, S58).

  When the cooperation between the mobile terminal 100 and the in-vehicle terminal 300 is started, the content output control unit 103 of the mobile terminal 100 changes the output destination of the content to the in-vehicle terminal cooperation unit 104, and then passes through the in-vehicle terminal cooperation unit. To output to the in-vehicle terminal 300 (S59). The in-vehicle terminal 300 outputs the received content at the output unit 305 (S60). As a result, the content being played back on the mobile terminal 100 is output from the in-vehicle terminal 300.

(Operation / Effect according to this embodiment)
According to this embodiment, the user can select the portable terminal which cooperates with a vehicle-mounted terminal by selecting a seat. Although the identifier of a portable terminal exists as information which identifies a portable terminal, generally it is comprised with the character string with low low readability, and it is not easy to select a portable terminal by seeing an identifier. In the vehicle, the user is seated in a seat and can easily grasp who is seated in which seat. Therefore, the convenience of the user is improved by specifying the portable terminal by specifying the seat.

Moreover, in this embodiment, the identifier of the portable terminal is transmitted by human body communication between the portable terminal and the sheet sensor. By adopting such a configuration, the correspondence between the seat and the mobile terminal can be grasped. Moreover, since human body communication is employed, recognition is performed simply by sitting with the mobile terminal worn, and there is no need to perform a special operation, and the burden on the user does not increase.

(Second Embodiment)
In the first embodiment, the user has selected the seat position of the mobile terminal with which the user explicitly cooperates when the in-vehicle terminal and the mobile terminal cooperate. On the other hand, in this embodiment, priorities are stored in advance for a plurality of seats, and which mobile band terminal is to be linked is determined based on the priorities.

  FIG. 6 shows a schematic diagram of the cooperation system according to the present embodiment. The difference from the first embodiment (FIG. 1) is that the linked seat selection unit 303 has a seat priority storage unit 306. Accordingly, the processing content of the cooperative seat selection unit 303 is also different from that of the first embodiment. The other functional parts are the same as those in the first embodiment, and therefore, different parts will be mainly described.

  The seat priority storage unit 306 stores the priority of cooperation for each of a plurality of seats in which the seat sensor 200 in the vehicle is installed. FIG. 7 is a diagram illustrating an example of a table stored in the seat priority storage unit 306. Here, the smaller the numerical value, the higher the priority. Accordingly, high priority is given in the order of the driver seat, the passenger seat, the left rear seat, and the right rear seat.

  The seat priority storage unit 306 may be stored in the in-vehicle terminal 300 in advance. Or the screen similar to the seat selection screen (FIG. 4) in 1st Embodiment may be shown to a user, the input of a priority may be received from a user, and the content may be memorize | stored.

  Next, the operation of the cooperative seat selection unit 303 will be described. In the present embodiment, the linked seat selection unit 303 selects a portable terminal that automatically cooperates according to the contents of the seat priority storage unit 306 and the portable terminal position storage unit 302, not the input from the user. Specifically, among the mobile terminals stored in the mobile terminal position storage unit 302, the mobile terminal associated with the seat assigned the highest priority in the seat priority storage unit 306 is linked. Decide to do. When the seat priority storage unit 306 has the contents shown in FIG. 7 and the portable terminal position storage unit 302 has the contents shown in FIG. 3, the portable terminal “ Since ABCDEF1234 "exists, this mobile terminal is selected as the mobile terminal of the cooperation destination. If there is no portable terminal in the highest priority seat, it is confirmed whether there is a portable terminal in the next highest priority seat. Thus, by confirming in order from the seat with the highest priority, the portable terminal associated with the seat with the highest priority can be selected.

  By doing in this way, the portable terminal which cooperates can be determined, without receiving a user's input at the time of cooperation. Also, when linking an in-vehicle terminal and a mobile terminal, it may be more important to link with a mobile terminal seated in which seat than to link with a mobile terminal owned by a person. For example, it may be preferable to link with a mobile terminal of a user who is seated in a driver seat. In such a case, if the priority of the driver's seat is set higher in advance, the user's portable terminal seated in the driver's seat can be automatically linked.

  Note that it is not necessary to assign priorities to all seats, and priorities may not be assigned to some seats. Moreover, you may employ | adopt the setting not to perform cooperation.

(Third embodiment)
In 1st and 2nd embodiment, the identifier was received from the portable terminal by the human body communication part provided in the sheet | seat sensor. In the present embodiment, the identifier is received from the portable terminal by means other than human body communication.

  FIG. 8 shows a schematic diagram of the cooperation system according to the present embodiment. The main difference from the first embodiment (FIG. 1) is that the mobile terminal 100 and the sheet sensor 200 are provided with wireless power feeding units 105 and 203 instead of the human body communication unit, respectively. The wireless power feeding unit is a functional unit that enables power supply to the mobile terminal 100 in a contactless manner. Wireless power feeding methods include an electromagnetic induction method that uses electromagnetic induction between coils, a radio wave method that changes current to electromagnetic waves and transmits / receives it via an antenna, and an electromagnetic resonance method that uses electromagnetic field resonance. Exists. In this embodiment, any wireless power feeding method can be adopted. Note that when wireless power feeding is performed (for example, at the start thereof), the mobile terminal 100 acquires an identifier from the terminal identifier storage unit 101 and transmits the identifier to the wireless power feeding unit 203 of the sheet sensor 200. Thereby, the sheet sensor 200 when performing wireless power feeding can grasp the identifier of the mobile terminal that is performing wireless power feeding.

  Note that the wireless power supply unit 203 provided in the seat has a wireless power supply range designed to perform wireless power supply only to the mobile terminal 100 in the vicinity of the seat, or is wireless to the mobile terminals 100 in a plurality of seats. Although power can be supplied, it is preferable to be able to grasp to which portable terminal 100 the wireless power supply is performed by detecting the directivity of the received radio wave. By doing in this way, the seat sensor 200 can grasp | ascertain which portable terminal (identifier) is matched with which seat.

  As in the first embodiment, the seat sensor 200 notifies the portable terminal position specifying unit 301 of the in-vehicle terminal 300 of the correspondence between the portable terminal (identifier thereof) and the seat position via the identifier notification unit 202.

  Even with such a configuration, the same effects as those of the first and second embodiments can be obtained. However, since human body communication is not used in this embodiment, even if only the mobile terminal 100 is placed on the seat and the user is not seated, it can be added as a candidate for cooperation.

  On the other hand, in the present embodiment as well, when only the portable terminal 100 possessed by the user sitting on the seat is set as a candidate for cooperation, the following may be performed. In other words, the seat sensor 200 is provided with a load sensor, and when the user is seated on the seat (the load sensor has a predetermined input or more) and only when the wireless power feeding is performed, The correspondence between the portable terminal 100 and the seat is notified. In this way, the mobile terminal can be a candidate for cooperation only when the user is seated on the seat.

  In the present embodiment, the correspondence relationship between the seat and the mobile terminal is grasped based on the identifier of the mobile terminal 100 transmitted at the time of wireless power supply. Is possible. That is, a wired power supply unit is installed in each seat, and the positional relationship between the seat and the mobile terminal can be grasped by transmitting the identifier of the mobile terminal to the wired power supply unit when performing power supply by wired connection. Therefore, it is possible to select a mobile terminal that cooperates with the in-vehicle terminal by wireless communication depending on the seat.

(Modification)
The above description is an example of an embodiment of the present invention, and the present invention can be implemented in various forms other than the above.

In the above description, the example in which the output from the mobile terminal is output to the display screen of the in-vehicle terminal as the cooperation between the in-vehicle terminal and the mobile terminal has been described. However, the content of the cooperation need not be limited to this. On the contrary, the output from the in-vehicle terminal may be output to the display screen of the portable terminal. Further, it is not necessary to limit the output to the example of displaying on the screen. The cooperation between the in-vehicle terminal and the portable terminal may be an arbitrary process performed by performing communication (wireless communication) between these terminals and performing according to the communication content. That is, the present invention can be understood as selecting a portable terminal that communicates with an in-vehicle terminal by specifying a seat. Note that the communication between the in-vehicle terminal and the portable terminal is not particularly limited, and may be bidirectional communication or unidirectional communication in any direction.

  Moreover, although the case where the vehicle has four seats has been described as an example in the above description, the number of seats is not particularly limited, and may be more or less than four. For example, the present invention can be applied to a microbus having 11 to 29 seats or a large bus having 30 or more seats. At this time, it is not necessary to provide seat sensors for all seats, and seat sensors may be provided only for some seats.

  Note that the seat sensors described in the first to third embodiments may be provided in only one seat. In this case, the portable terminal from which the sheet sensor has acquired the identifier can be preferentially determined as the cooperation destination. For example, when displaying a list of identifiers of mobile terminals and allowing the user to select, information may be presented to the user in a form that allows the user to know which mobile terminal is associated with the sheet sensor, or selection from the user Alternatively, the mobile terminal associated with the sheet sensor may be automatically selected. In addition, when there is only one sensor, it is not necessarily provided in the seat.
