In addition, a conventionally well-known thing can be used for the technique etc. which register beforehand the communication terminal to be used for a vehicle-mounted apparatus (not shown).

  Next, control processing of the communication terminal connection management system of the present embodiment configured as described above will be described. FIG. 3 is a diagram showing a flowchart of processing in the communication terminal connection management system according to the first embodiment of the present invention. This flowchart is started when the vehicle is started (engine or motor is started, etc.), and is ended when the vehicle is stopped (engine or motor is turned off, etc.).

  In FIG. 3, when the processing of the communication terminal connection management system is started in step S100 due to an engine start or the like, the process proceeds to step S101, where the communication unit registered in the storage unit 160 by the receiving unit 120 is continued. It is determined whether or not radio waves are detected. If the decision result in the step S101 is NO, the process proceeds to a step S107, and the communication terminal connection management unit 150 maintains a non-connected state.

  On the other hand, if the decision result in the step S101 is YES, the process advances to a step S102 to determine whether or not a passenger is detected by the driver seat sensor 131. When the determination result in step S102 is YES, the process proceeds to step S103, and the communication terminal connection management unit 150 sets the connection state between the communication terminal and the in-vehicle device.

When the determination result of step S102 is NO, the process further proceeds to step S104, and it is determined whether or not a seat sensor other than the driver's seat has detected a passenger. When this determination result is YES, that is, even when no occupant is detected in the driver's seat, if the occupant is detected in other seats, the communication terminal is used by the occupant remaining in the vehicle. Therefore, the process proceeds to step S105, and the communication terminal connection management unit 150 sets the connection state between the communication terminal and the in-vehicle device. on the other hand,
On the other hand, when the determination result in step S104 is NO, no passengers are present in any seat, so the process proceeds to step S106, and the communication terminal connection management unit 150 does not connect between the communication terminal and the in-vehicle device. Connected.

  FIG. 4 is a diagram illustrating a processing table of the communication terminal connection management unit 150 based on the detection of the sheet sensor in a state where the reception unit 120 detects the radio wave of the communication terminal registered in the storage unit 160. . This table shows the processing according to the flowchart shown in FIG. 3 in the table.

Therefore, even if the driver gets off the communication terminal that has been performing wireless communication with the in-vehicle device, the disconnection control is performed if another ride member is detected by the seat sensor. It can be used immediately after re-boarding.

  Next, another embodiment of the present invention will be described. FIG. 5 is a diagram schematically showing a configuration of a communication terminal connection management system according to the second embodiment of the present invention, and FIG. 6 is an outline of a block configuration of the communication terminal connection management system according to the second embodiment of the present invention. FIG. 5 and 6, the same configuration as that of the first embodiment is shown.

The difference between the first embodiment and the second embodiment is that, in the first embodiment, only one receiving unit 120 that receives radio waves of communication terminals in the vehicle is provided. In the second embodiment, four receiving sections are provided in the vicinity of each of the four seats of the driver seat, the passenger seat, the rear right seat, and the rear left seat. That is, in the receiving unit of the second embodiment, there are four drivers seat receiving unit 121, passenger seat receiving unit 122, rear right seat receiving unit 123, and rear left seat receiving unit 124.

The priority connection order table is a table for determining which communication terminal is to be preferentially connected to the in-vehicle device depending on the seat where the communication terminal exists when there are a plurality of communication terminals in the vehicle. The example shown in FIG. 7B shows an example in which the priority decreases in the order of driver seat → passenger seat → rear right seat → rear left seat. For example, this is a case assuming that the vehicle is used by a family, and the connection priority of the communication terminal of the passenger who is supposed to board the driver's seat is the highest.

  FIG. 8 shows another example of the priority connection order table. The example shown in FIG. 8 shows an example in which the priority decreases in the order of rear right seat → rear left seat → passenger seat → driver seat. This is, for example, a priority connection order table when the vehicle is used as a commercial vehicle, and the connection priority order of the passenger's communication terminal assumed to board the rear right seat is the highest.

  It is preferable that the priority connection order table stored in the storage unit 160 can be appropriately set and changed as shown in FIG. 7B and FIG.

  In the second embodiment, the connection / disconnection of the communication terminal is determined by referring also to the priority connection order table. Even if the communication terminal exists on the predetermined sheet, the sheet If there is no passenger on the top, it is considered that it is not useful to manage the communication terminal and the in-vehicle device so that the passenger is present on the seat. To be connected to the highest priority communication terminal.

  In step S202, it is determined which communication terminal is present on which seat from the strength of the radio waves received by the driver seat receiver 121, the passenger seat receiver 122, the rear right seat receiver 123, and the rear left seat receiver 124. Get location information. In addition, what is known until now can be utilized suitably about the technique which acquires the positional information on a communication terminal from the intensity | strength of the electromagnetic wave received by several receiving part.

  In step S203, the seat on which the occupant is seated is determined based on the detection / non-detection states of the driver seat sensor 131, the passenger seat sensor 132, the rear right seat sensor 133, and the rear left seat sensor 134. The passenger position information is acquired.

  In step S204, it is determined whether or not there is a sheet with (communication terminal position) = (sheet sensor detection position). That is, in step S204, it is determined whether or not there is a communication terminal and a seat on which a passenger is sitting. If the determination in step S204 is yes, the process proceeds to step S205. If the determination is no, the process proceeds to step S206.

  In step S205, communication is performed so that the communication terminal existing in the seat with the highest priority is connected to the in-vehicle device by referring to the priority connection order table among the seats detected by the communication terminal and detected by the passenger. The terminal connection management unit 150 performs connection management.

  In step S205, the communication terminal connection management unit 150 refers to the priority connection order table and performs management so as to connect the communication terminal existing in the driver's seat, which is the highest priority seat, and the in-vehicle device.

  Next, when the example of FIG. 11 is applied to the previous flowchart, in the determination in step S204, the seat where (communication terminal position) = (seat sensor detection position) is the seat in the front passenger seat and the rear left seat. Therefore, also in this case, the process proceeds to step S205.

  In step S205, the communication terminal connection management unit 150 refers to the priority connection order table and manages the connection to the communication terminal existing in the passenger seat, which is the seat with the highest priority.

  Next, when the example of FIG. 12 is applied to the previous flowchart, in the determination of step S204, since the seat where (communication terminal position) = (seat sensor detection position) is the seat of the rear right seat, In this case, the process proceeds to step S205.

  In step S205, the communication terminal connection management unit 150 refers to the priority connection order table and manages the connection with the communication terminal existing in the rear right seat that is the highest priority seat. Here, in the example of FIG. 12, if it is determined only by the priority connection order table, the communication terminal is detected on the driver's seat, so that management is performed so as to connect to the communication terminal existing in the driver's seat. Become. However, when the detection information of the seat sensor is also taken into consideration, it is considered that there is no boarding vehicle on the driver's seat and there is no significance in connecting the communication terminal on the driver's seat and the in-vehicle device. Therefore, in the present embodiment, when there is a sheet where (communication terminal position) = (sheet sensor detection position), connection / non-connection of the communication terminal connection management unit 150 is determined by the process shown in step S205. Therefore, more effective communication terminal connection management is performed.

  When the determination in step S204 is NO, in step S206 that proceeds, the communication terminal connection management unit 150 refers to the priority connection order table, and the communication terminal connection management unit 150 manages the connection so as to connect to the communication terminal existing in the highest priority sheet. I do.

A connection management example of the communication terminal connection management unit 150 in step S206 will be specifically described with reference to FIG.
