As shown in FIG. 3, when a voltage is applied between the reference electrode 23A of the second human body coupling electrode 23 and the transmission / reception electrode 23B in the mobile terminal 20, an electric field is generated around the second human body coupling electrode 23. As a result, the distribution of the electric charge C on the surface of the human body of the occupant J is biased. An electric field is generated in the vicinity of the human body due to the distribution of the electric charge C on the surface of the human body. The electric field generated on the surface of the human body is not transmitted as far as electromagnetic waves, but acts only on objects existing in the immediate vicinity of the human body. The first human body coupling electrode 13 is embedded in the seat portion 205A of the seat 205 in which the occupant J is seated, and does not directly touch the occupant J. However, since it is arranged in the immediate vicinity of the occupant J (for example, within several cm), an electric field generated on the surface of the occupant J's body acts on the first human body coupling electrode 13.

The store-side communication device 30 has a third communication unit 32 that communicates with the outside based on an output signal from the third control unit 31. The third communication unit 32 is arranged inside the building 401.

The store-side communication device 30 has a first buried electrode 33 and a second buried electrode 34. As shown by the broken line in FIG. 4, the first embedded electrode 33 is embedded in the traveling path 402 in a predetermined range including the portion where the first stop line 403 is drawn. As shown by the alternate long and short dash line in FIG. 4, the second embedded electrode 34 is embedded in the traveling path 402 in a predetermined range including the portion where the second stop line 404 is drawn.

It emits radio waves in the above frequency band used in. Further, when the first embedded electrode 33 and the second embedded electrode 34 receive radio waves from other electrodes, the third communication unit 32 generates a demodulated signal obtained by demodulating the received signal and outputs the demodulated signal to the third control unit 31. do.

As shown in FIG. 5, the store-side communication device 30 executes a vehicle detection process for detecting a vehicle 200 that has entered the first stop line 403 (step S500). In the vehicle detection process, the third control unit 31 generates the response request signal M100. The response request signal M100 is a signal that the device that has received the signal requests the store-side communication device 30 to transmit the response signal M101. The third control unit 31 outputs the response request signal M100 to the third communication unit 32 at predetermined time intervals. The third communication unit 32 transmits a response request signal M100 from the first embedded electrode 33 based on the output signal from the third control unit 31. When there is no vehicle 200 stopped at the first stop line 403, the response signal M101 is not returned even if the response request signal M100 is transmitted from the first embedded electrode 33. Therefore, the third control unit 31 determines that the vehicle 200 is not stopped when the response signal M101 is not input from the first embedded electrode 33.

On the other hand, when the vehicle 200 enters in front of the store-side external device 40 and is stopped at the first stop line 403, the vehicle electrodes 14 and the first buried electrodes provided on the floor portion 202 of the vehicle 200 33 is placed in close proximity to the 33. Therefore, the vehicle electrode 14 and the first embedded electrode 33 are in a state of being wirelessly connected to each other, and are in a state of being capable of direct communication without going through an external communication network. When the response request signal M100 is transmitted from the first embedded electrode 33 in this state, the response request signal M100 is transmitted to the first communication unit 12 through the vehicle electrode 14. The first communication unit 12 outputs the received response request signal M100 to the first control unit 11. The first control unit 11 generates a response signal M101 for the received response request signal M100 and performs a response process to output the response signal M101 to the first communication unit 12 (step S501). The first communication unit 12 transmits the response signal M101 from the vehicle electrode 14 based on the output signal from the first control unit 11. When the store-side communication device 30 receives the response signal M101 from the vehicle electrode 14 by the first embedded electrode 33, there is a vehicle 200 that enters the first stop line 403 and is stopped in front of the store-side external device 40.

The third control unit 31 outputs the first authentication signal M201 to the third communication unit 32. The third communication unit 32 transmits the first authentication signal M201 from the first embedded electrode 33 based on the output signal from the third control unit 31. The store-side communication device 30 and the vehicle-mounted communication device 10 directly communicate wirelessly between the first embedded electrode 33 and the vehicle electrode 14. As a result, the first communication unit 12 of the vehicle-mounted communication device 10 receives the first authentication signal M201. The first communication unit 12 outputs the received first authentication signal M201 to the first control unit 11. The first control unit 11 authenticates the store-side communication device 30 by receiving the first authentication signal M201 (step S504).

Therefore, the second authentication signal M202 transmitted from the first human body coupling electrode 13 is received by the second human body coupling electrode 23 of each mobile terminal 20 and output to the second communication unit 22 of each mobile terminal 20. In each mobile terminal 20, when the second communication unit 22 receives the second authentication signal M202, the second communication unit 22 outputs the received second authentication signal M202 to the second control unit 21. The second control unit 21 authenticates the in-vehicle communication device 10 and the store-side communication device 30 by receiving the second authentication signal M202 (step S505).

After that, the second control unit 21 generates the third authentication signal M203. The third authentication signal M203 includes the authentication information of the mobile terminal 20. The second control unit 21 outputs the third authentication signal M203 to the second communication unit 22. The second communication unit 22 transmits the third authentication signal M203 from the second human body coupling electrode 23 based on the output signal from the second control unit 21. As a result, the first human body coupling electrode 13 receives the third authentication signal M203 from each mobile terminal 20 via human body communication. The first human body coupling electrode 13 outputs the third authentication signal M203 received from the second human body coupling electrode 23 of each mobile terminal 20 to the first communication unit 12. In the vehicle-mounted communication device 10, when the first communication unit 12 receives the third authentication signal M203, the first communication unit 12 outputs the received third authentication signal M203 to the first control unit 11. The first control unit 11 authenticates each mobile terminal 20 by receiving the third authentication signal M203 transmitted from each mobile terminal 20 (step S506).

The first control unit 11 of the vehicle-mounted communication device 10 generates the fourth authentication signal M204. The fourth authentication signal M204 includes the authentication information of the vehicle-mounted communication device 10 and the authentication information of each mobile terminal 20. The first control unit 11 outputs the fourth authentication signal M204 to the first communication unit 12. The first communication unit 12 transmits the fourth authentication signal M204 from the vehicle electrode 14 based on the output signal from the first control unit 11. In the store-side communication device 30, when the third communication unit 32 receives the fourth authentication signal M204 via wireless direct communication between the first embedded electrode 33 and the vehicle electrode 14, the third communication unit 32 receives the fourth. The authentication signal M204 is output to the third control unit 31. The third control unit 31 authenticates the in-vehicle communication device 10 and each mobile terminal 20 by receiving the fourth authentication signal M204 (step S507). As a result, mutual authentication between the in-vehicle communication device 10, the first mobile terminal 20A, the second mobile terminal 20B, and the store-side communication device 30 is completed (step S508).

As shown in FIG. 6, when the mutual authentication is completed, the store-side communication device 30 executes the occupant information collection process for collecting the information of the occupant J on board the vehicle 200 (S600). In the occupant information collection process, the third control unit 31 generates the personal information request signal M300. The personal information request signal M300 is a signal that requests the mobile terminal 20 that has received the signal to transmit the personal information recorded in the recording unit 26 to the store-side communication device 30. The third control unit 31 outputs the personal information request signal M300 to the third communication unit 32. The third communication unit 32 transmits the personal information request signal M300 from the first embedded electrode 33 based on the output signal from the third control unit 31. When the personal information request signal M300 is transmitted from the first embedded electrode 33, the personal information request signal M300 is received by the vehicle electrode 14 and output to the first communication unit 12. The first communication unit 12 outputs the received personal information request signal M300 to the first control unit 11.

When the first control unit 11 receives the personal information request signal M300, the first control unit 11 outputs the signal to the first communication unit 12 and causes the first human body coupling electrode 13 to transmit the signal. The personal information request signal M300 transmitted from the first human body coupling electrode 13 is received by the second human body coupling electrode 23 of each mobile terminal 20 and output to the second communication unit 22 of each mobile terminal 20. The second communication unit 22 outputs the received personal information request signal M300 to the second control unit 21. The second control unit 21 performs response processing based on the personal information request signal M300 (step S601).

In the response process, the second control unit 21 of each mobile terminal 20 generates a personal information signal M301 including personal information (age, gender, etc.) recorded in advance in the recording unit 26, and outputs the personal information signal M301 to the second communication unit 22. .. The second communication unit 22 transmits the personal information signal M301 from the second human body coupling electrode 23 based on the output signal from the second control unit 21. As a result, the first human body coupling electrode 13 receives the personal information signal M301 from each mobile terminal 20 via human body communication. The first human body coupling electrode 13 outputs the personal information signal M301 received from the second human body coupling electrode 23 of each mobile terminal 20 to the first communication unit 12. When the first communication unit 12 receives the personal information signal M301, the first communication unit 12 outputs the received personal information signal M301 to the first control unit 11. The first control unit 11 transmits the personal information signal M301 transmitted from each mobile terminal 20 to the vehicle electrode 14 via the first communication unit 12. When the personal information signal M301 is transmitted from the vehicle electrode 14, the personal information signal M301 is received by the first embedded electrode 33 and output to the third communication unit 32. The third communication unit 32 outputs the received personal information signal M301 to the third control unit 31. In this way, the store-side communication device 30 receives the personal information signal M301 of each mobile terminal 20 transmitted from the in-vehicle communication device 10, so that the occupant J in the vehicle 200 stopped at the first stop line 403 Grasp the information (step S602).

In the vehicle communication system 100, when the vehicle 200 is stopped at the first stop line 403, communication between the store-side communication device 30 and the vehicle-mounted communication device 10 is directly performed between the first embedded electrode 33 and the vehicle electrode 14. It is done by communication. Further, communication between the vehicle-mounted communication device 10 and each mobile terminal 20 is performed by human body communication between the first human body coupling electrode 13 and the second human body coupling electrode 23. Then, communication between the store-side communication device 30 and each mobile terminal 20 is performed via the in-vehicle communication device 10. In the present embodiment, the control mode relating to the communication between the vehicle-mounted communication device 10 and each mobile terminal 20 and the control mode relating to the communication between the vehicle-mounted communication device 10 and the store-side communication device 30 are as described above. Therefore, in the following, detailed description of each control mode will be omitted.

When the personal information of each mobile terminal 20 is grasped in the store-side communication device 30, the recommended menu selection unit 35 selects a menu recommended for the occupant J from the menus that can be provided (step S603). For example, when the personal information of each mobile terminal 20 includes a child, the recommended menu selection unit 35 selects a kids menu for children, and the personal information of each mobile terminal 20 is a woman. If this is included, select a menu for women, etc.

When the recommended menu selection unit 35 selects the recommended menu, the store-side communication device 30 transmits the recommended menu signal M 302 including the recommended menu information to each mobile terminal 20 via the vehicle-mounted communication device 10. Upon receiving the recommended menu signal M302 in each mobile terminal 20, the second control unit 21 activates the drive-through application and causes the mobile display unit 25 to display the recommended menu (step S604). As a result, the owner of the mobile terminal 20 can grasp the recommended menu through the mobile display unit 25.

Further, the store-side communication device 30 causes the menu display unit 41 of the store-side external device 40 to display a recommended menu (step S605). As a result, the occupant J of the vehicle 200 can grasp the recommended menu not only by the mobile display unit 25 of the mobile terminal 20 but also by the menu display unit 41 of the store-side external device 40. Crew J displays the order screen of the drive-through application and decides the order by inputting the order contents. On the order screen, there is a representative order for all crew members J on either the first mobile terminal 20A or the second mobile terminal 20B, and an individual order can be made individually for each holder on each mobile terminal 20. It has an ordering function. In the present embodiment, the representative order is used to place an order for all crew members J from the first mobile terminal 20A. The owner of the first mobile terminal 20A inputs the order information for all the crew members J and decides the order (step S606).

When the order is determined, the first mobile terminal 20A transmits the order signal M303 to the store-side communication terminal via the vehicle-mounted communication device. When the store-side communication device 30 receives the order signal M303, it determines whether or not it is a representative order, and if it is a representative order, it does not wait for the reception of the order signal M303 from the other mobile terminal 20. The order is confirmed (step S607). The store-side communication device 30 confirms the order by associating it with at least one identification information of the in-vehicle communication device 10 and each mobile terminal 20. Then, the store-side communication device 30 displays the order contents on the store display unit 36, and transmits the order contents to the clerk in the building 401. As a result, the clerk creates the ordered product. When the store-side communication device 30 receives the order signal M303 and determines that it is not a representative order, that is, it determines that it is an individual order, it is from all the other authenticated mobile terminals 20. The order is confirmed after receiving the order signal M303.

After that, the third control unit 31 of the store-side communication device 30 outputs a signal to notify the voice guidance unit 42 of the store-side external device 40 (step S608). Based on the output signal from the third control unit 31, the voice guidance unit 42 automatically guides the occupant J to move the vehicle 200 to the delivery place of the product. According to this guidance, the occupant J moves the stopped vehicle 200 on the first stop line 403 to the second stop line 404 and stops the vehicle (step S609).

The store-side communication device 30 detects the vehicle 200 that has entered the second stop line 404, and detects the vehicle-mounted communication device 10 of the vehicle 200 and the mobile terminal 20 possessed by the occupant J for mutual authentication. The authentication process is executed (step S610). In this process, the same process as in steps S500 to S508 of FIG. 5 is executed. That is, in the detection authentication process, the third control unit 31 first generates the response request signal M100. The third control unit 31 outputs the response request signal M100 to the third communication unit 32 at predetermined time intervals. The third communication unit 32 transmits a response request signal M100 from the second embedded electrode 34 based on the output signal from the third control unit 31. When there is no vehicle 200 stopped at the second stop line 404, the response signal M101 is not returned even if the response request signal M100 is transmitted from the second embedded electrode 34. Therefore, the third control unit 31 determines that the vehicle 200 is not stopped when the response signal M101 is not input from the second embedded electrode 34.

On the other hand, when the vehicle 200 has entered the second stop line 404 and is stopped, the vehicle electrode 14 provided on the floor portion 202 of the vehicle 200 and the second buried electrode 34 are arranged in close proximity to each other. Will be done. Therefore, the vehicle electrode 14 and the second embedded electrode 34 are in a state of being wirelessly connected to each other, and are in a state of being capable of direct communication without going through an external communication network. When the response request signal M100 is transmitted from the second embedded electrode 34 in this state, the response request signal M100 is transmitted to the first communication unit 12 through the vehicle electrode 14. The first communication unit 12 outputs the received response request signal M100 to the first control unit 11. The first control unit 11 generates a response signal M101 for the received response request signal M100, and performs a response process to output the response signal M101 to the first communication unit 12. The first communication unit 12 transmits the response signal M101 from the vehicle electrode 14 based on the output signal from the first control unit 11. When the store-side communication device 30 receives the response signal M101 by the second embedded electrode 34, it detects that there is a vehicle 200 stopped at the second stop line 404.

After that, the store-side communication device 30 executes the authentication process. In the authentication process, first, the store-side communication device 30 transmits the first authentication signal M201 to the vehicle-mounted communication device 10 through the second embedded electrode 34. The communication at this time is performed by direct communication between the second embedded electrode 34 and the vehicle electrode 14. As a result, the in-vehicle communication device 10 authenticates the store-side communication device 30. After that, the vehicle-mounted communication device 10 transmits the second authentication signal M202 to each mobile terminal 20. As a result, each mobile terminal 20 authenticates the in-vehicle communication device 10 and the store-side communication device 30. Then, each mobile terminal 20 transmits the third authentication signal M203 to the in-vehicle communication device 10. As a result, the vehicle-mounted communication device 10 authenticates each mobile terminal 20. The communication between the in-vehicle communication device 10 and each mobile terminal 20 is performed by human body communication via the occupant J. After that, the vehicle-mounted communication device 10 transmits the fourth authentication signal M204 to the store-side communication device 30 through the second embedded electrode 34. As a result, the store-side communication device 30 authenticates the in-vehicle communication device 10 and each mobile terminal 20. By transmitting and receiving each of these authentication signals, mutual authentication between the in-vehicle communication device 10, the first mobile terminal 20A, the second mobile terminal 20B, and the store-side communication device 30 is completed. By this authentication, the store-side communication device 30 grasps the contents of the order received from the occupant J of the vehicle 200 stopped at the second stop line 404.

In the store-side communication device 30, when the ordered product is completed (step S611), the third control unit 31 generates a window opening operation signal M304 for opening the window of the vehicle 200. The store-side communication device 30 transmits the window opening operation signal M304 to the vehicle-mounted communication device 10 through the second embedded electrode 34. When the vehicle-mounted communication device 10 receives the window opening operation signal M304, the first control unit 11 outputs a control signal to the window opening / closing unit 15 so as to open the window of the driver's seat of the vehicle 200. The window opening / closing unit 15 controls the operation of the actuator based on the control signal output from the first control unit 11 to open the driver's seat window to the fully open state (step S612). After that, the clerk delivers the product to the occupant J through the window of the driver's seat (step S613). When the store-side communication device 30 determines that the delivery of the product is completed (step S614), the third control unit 31 generates a window closing operation signal M305 for closing the window of the vehicle 200. The determination of the completion of delivery of the product can be made, for example, based on the image of the camera placed at the delivery location or the input of the delivery completion operation from the clerk.

The store-side communication device 30 transmits the window closing operation signal M305 to the vehicle-mounted communication device 10 through the second embedded electrode 34. When the vehicle-mounted communication device 10 receives the window closing operation signal M305, the first control unit 11 outputs a control signal to the window opening / closing unit 15 so as to close the window of the driver's seat of the vehicle 200. The window opening / closing unit 15 closes the driver's seat window to a fully closed state by controlling the operation of the actuator based on the control signal output from the first control unit 11 (step S615).

After that, the store-side communication device 30 performs payment processing (step S616). In the settlement process, the third control unit 31 generates the settlement signal M306. The payment signal M306 includes information such as the payment fee of the order content and the payment destination. The third control unit 31 outputs the settlement signal M306 to the third communication unit 32. The third communication unit 32 transmits the settlement signal M306 from the second embedded electrode 34 to the mobile terminal 20 based on the output signal from the third control unit 31. In the present embodiment, the settlement signal M306 is transmitted to the first mobile terminal 20A for which the representative order is placed. When the payment signal M306 is received in the first mobile terminal 20A, the second control unit 21 controls the electronic payment unit 27 to perform electronic payment processing by a well-known method (step S617). As a result, the settlement is completed, and the crew member J can start the vehicle 200 outside the store 400 without directly exchanging money or the like with the store clerk.

As described above, in the present embodiment, when the vehicle 200 is stopped at the first stop line 403, the first buried electrode 33 and the vehicle electrode 14 are connected, and the vehicle 200 is stopped at the second stop line 404. Occasionally, the second buried electrode 34 and the vehicle electrode 14 are connected. This enables direct wireless communication between the vehicle-mounted communication device 10 and the store-side communication device 30 both when the vehicle 200 is stopped at the first stop line 403 and the second stop line 404. In the present embodiment, in the store-side communication device 30, the first buried electrode 33 and the second buried electrode 34 correspond to the second external electrode, and the periphery of the first stop line 403 and the second stop line 404 is a predetermined communication range. It becomes.

The operation and effect of this embodiment will be described.
(1) In the present embodiment, communication between the in-vehicle communication device 10 and the mobile terminal 20 is performed by human body communication. In human body communication, the vehicle-mounted communication device 10 and the mobile terminal 20 are connected using the occupant J as a communication path. Therefore, the vehicle-mounted communication device 10 and the mobile terminal 20 can be virtually directly connected by wire, as compared with the case where an external communication network is used between the vehicle-mounted communication device 10 and the mobile terminal 20. , These communication paths are less likely to be interfered with from the outside. Further, the vehicle electrode 14 mounted on the vehicle 200 and the first buried electrode 33 and the second buried electrode 34 embedded in the travel path 402 of the store 400 are connected to directly limit the communicable area. connect.

It is difficult to connect and disconnect quickly. In this respect, in the present embodiment, when the vehicle 200 comes to the store 400 and is stopped at the first stop line 403, the vehicle electrode 14 of the vehicle-mounted communication device 10 is connected to the first embedded electrode 33 of the store-side communication device 30. Communication becomes possible, and when the vehicle is stopped at the second stop line 404, the vehicle electrode 14 of the vehicle-mounted communication device 10 can communicate with the second embedded electrode 34 of the store-side communication device 30. Therefore, it is possible to ensure the speed of connection between the mobile terminal 20 and the store-side communication device 30 while appropriately ensuring the safety in the communication between the mobile terminal 20 and the store-side communication device 30.

(4) In the present embodiment, when the vehicle electrode 14 and the first embedded electrode 33 are connected, personal information recorded in the mobile terminal 20 is transmitted to the store-side communication device 30 via the vehicle-mounted communication device 10. Will be sent. Therefore, the detailed matters of the occupant J can be grasped as compared with the case where the clerk visually confirms the occupant J inside the vehicle 200 by using a camera or the like. In this way, by grasping even information that cannot be visually understood, it becomes possible to develop a service tailored to the occupant J, such as selecting a recommended menu more suitable for the occupant J at the store 400. Therefore, it can also contribute to improving the quality of the service provided from the store 400 to the occupant J.

(5) When the personal information registered in the mobile terminal 20 is transmitted to the store-side communication device 30 to provide a service, it is more important to ensure the safety in the communication between the mobile terminal 20 and the store-side communication device 30. Become. In the present embodiment, since it is possible to ensure the safety of communication between the mobile terminal 20 and the store-side communication device 30, it is possible to realize a vehicle communication system for transmitting and receiving information including personal information, and it can be applied to various services. ..

The above-mentioned first embodiment can also be carried out in the following embodiments in which the above-mentioned first embodiment is appropriately modified.
-The recommended menu may not be displayed on the store-side external device 40. In this case, the store-side external device 40 can display a list of all menus.

-A voice input unit capable of voice input from the clerk is provided in the building 401 of the store 400, and after the order from the occupant J is confirmed, the clerk inputs voice to the voice input unit to the vehicle 200. It is also possible to notify the movement. Further, after the store-side communication device 30 confirms the order, the third control unit 31 outputs a notification signal to notify the mobile display unit 25 of the mobile terminal 20 of the movement of the vehicle 200 (characters, images, etc.). ) May be displayed. Further, after the store-side communication device 30 confirms the order, the third control unit 31 outputs a notification signal so that a voice announcement to move the vehicle 200 is sent from the voice output unit of the mobile terminal 20. You may.

-As an ordering method, an example of operating a mobile terminal 20 to determine an order has been described, but the ordering method is not limited to this. For example, the store-side external device 40 may be provided with a voice transmission unit for transmitting voice in the building 401, and the occupant J may convey the order to the store clerk by voice order.

-Although the recommended menu is displayed and the vehicle 200 is guided by using the store-side external device 40, it is possible to add the function to other devices. For example, a display unit and a voice unit are further provided as a configuration of the vehicle-mounted communication device 10, a signal of information regarding a recommended menu from the store-side communication device 30 is received by the vehicle-mounted communication device 10, and the recommended menu is displayed on the display unit. It is also possible to display it. Further, it is also possible for the vehicle-mounted communication device 10 to receive a signal of information regarding the movement guidance from the store-side communication device 30, and the voice unit to perform the movement guidance by voice. When such a configuration is adopted, both the store-side external device 40 and the in-vehicle communication device 10 may be used to display recommended menus and guide the movement of the vehicle 200, or the store-side external device 40 may be used. By omitting it, the recommended menu may be displayed or the movement guidance of the vehicle 200 may be performed only by the vehicle-mounted communication device 10. In addition to the configuration in which the in-vehicle communication device 10 is provided with the display unit and the voice unit, it is also possible to configure the vehicle-mounted communication device 10 with the display unit and the voice unit of the car navigation device mounted on the vehicle.

-It is also possible to omit the window opening / closing portion 15. In this case, when the ordered product is completed, the window may be opened by the operation of the occupant J to receive the product.
-The execution timing of the payment process in step S616 can be changed as appropriate. For example, it is also possible to execute the product after the delivery of the product in the process of step S614 and at a timing before the window closing process of step S615. It is also possible to execute the payment process when the vehicle 200 is stopped at the first stop line 403. In this case, the settlement process may be executed after the order is determined in the process of step S606. It is also possible to omit the payment process. In this case, money may be exchanged directly with the clerk and the order fee may be paid.

-Past order history and the like may be recorded as personal information to be recorded in advance in the mobile terminal 20. In this case, the recommended menu selection unit 35 selects the recommended menu in consideration of the contents of the past order history. This makes it possible to create a recommended menu that more reflects the tastes of occupant J. In addition, by including information such as requesting to order only drinks in personal information, it is possible to display only the drink menu without displaying the food menu. This makes it possible to select a recommended menu according to the intention of crew member J.

The burying range of the first buried electrode 33 and the second buried electrode 34 is not limited to a range that exceeds the length in the width direction and the front-rear direction of the vehicle 200. For example, the buried range of the first buried electrode 33 may not exceed the length in the width direction and the front-rear direction of the vehicle 200. Even in such a case, the vehicle electrode 14 and the first buried electrode 33 are wirelessly connected by burying the first buried electrode 33 in a range facing the vehicle 200 stopped at the first stop line 403. It can be in the state of being. The same applies to the second embedded electrode 34.

-The second embedded electrode 34 does not necessarily have to be provided. For example, when it is not necessary for the vehicle-mounted communication device 10 and the store-side communication device 30 to communicate with each other when the vehicle 200 is stopped at the second stop line 404, the second embedded electrode 34 can be omitted. Is.

As shown in FIG. 8, the store 410 has a building 411 in which a clerk is placed, and a travel path 412 extending in front of the building 411 for the vehicle 200 to travel. The building 411 has a roof 411A that covers the upper part of the runway 412 and an entrance 411B. A stop line 413 is drawn on the runway 412. The stop line 413 is drawn to stop the vehicle 200 in front of the entrance 411B of the building 411.

As shown in FIGS. 7 and 8, the store-side communication device 70 has a third control unit 71 that controls communication with the outside. The third control unit 71 is arranged inside the building 411. The third control unit 71 includes a CPU, RAM, ROM and the like (not shown), and controls communication with the outside by executing a program stored in a recording device such as ROM and RAM by the CPU. The store-side communication device 30 has a third communication unit 72 that communicates with the outside based on an output signal from the third control unit 71. The third communication unit 72 is arranged inside the building 411.

The store-side communication device 70 has an embedded electrode 73. As shown in FIG. 8, the embedded electrode 73 is embedded in the traveling path 412. The buried electrode 73 is arranged on the rear side (right side in FIG. 8) of the stop line 413 in the traveling direction (direction indicated by the arrow in FIG. 8) when the vehicle 200 enters the store 410. It is desirable that the buried electrode 73 is arranged at the entrance of the traveling path 412 when the vehicle 200 enters the store 410. The embedded electrode 73 is provided in the traveling path 412 so as to have a predetermined length in the traveling direction. When entering the store 410, the vehicle 200 passes above the buried electrode 73, then proceeds to the front of the building 411 and stops at the stop line 413. As shown in FIG. 7, the embedded electrode 73 is connected to the third communication unit 72. The third communication unit 72 causes short-range wireless communication to be executed between the embedded electrode 73 and the outside. That is, the third communication unit 72 modulates the amplitude of the communication data of the AC signal output from the third control unit 71 to generate a modulated signal, and the radio wave in the above frequency band used for short-range communication from the embedded electrode 73.

Further, when the embedded electrode 73 receives a radio wave from another electrode, the third communication unit 72 generates a demodulated signal obtained by demodulating the received signal and outputs the demodulated signal to the third control unit 71.

The store-side communication device 70 has a store display unit 74 for displaying various information such as occupant information of the vehicle 200 that has entered the store for the store clerk in the building 411.
Next, the contents of the dealer warehousing service using the vehicle communication system 110 will be described. In the following, a case where two occupants J are on board the vehicle 200, that is, a case where two mobile terminals 60, a first mobile terminal 60A and a second mobile terminal 60B, are inside the vehicle 200 will be described as an example. do.

As shown in FIG. 9, the store-side communication device 70 detects the vehicle 200 that has entered the store, and mutually authenticates the vehicle-mounted communication device 50 of the vehicle 200 and the mobile terminal 60 possessed by the occupant J. The detection authentication process for performing the detection authentication process is executed (step S800). In this process, the same process as in steps S500 to S508 of FIG. 5 of the first embodiment is executed. That is, in the detection authentication process, the third control unit 71 first generates the response request signal M100. The third control unit 71 outputs the response request signal M100 to the third communication unit 72 at predetermined time intervals. The third communication unit 72 transmits the response request signal M100 from the embedded electrode 73 based on the output signal from the third control unit 71. It should be noted that this time interval is set to a time correspondingly shorter than the passing time when the vehicle 200 passes on the buried electrode 73 of the traveling path 412. If there is no vehicle 200 passing over the buried electrode 73, the response request signal M100 is not returned even if the response request signal M100 is transmitted from the buried electrode 73. Therefore, the third control unit 71 determines that the vehicle 200 has not entered the store when the response signal M101 is not input from the embedded electrode 73.

On the other hand, when the vehicle 200 passes over the buried electrode 73, the vehicle electrode 54 provided on the floor portion 202 of the vehicle 200 and the buried electrode 73 are arranged in close proximity to each other. Therefore, the vehicle electrode 54 and the buried electrode 73 are in a state of being wirelessly connected to each other, and are in a state of being capable of direct communication without going through an external communication network such as wireless. When the response request signal M100 is transmitted from the embedded electrode 73 in this state, the response request signal M100 is transmitted to the first communication unit 52 through the vehicle electrode 54. The first communication unit 52 outputs the received response request signal M100 to the first control unit 51. The first control unit 51 generates a response signal M101 for the received response request signal M100 and performs a response process to output the response signal M101 to the first communication unit 52. The first communication unit 52 transmits a response signal M101 from the vehicle electrode 54 based on the output signal from the first control unit 51. When the store-side communication device 70 receives the response signal M101 by the embedded electrode 73, the store-side communication device 70 detects the entry of the vehicle 200 into the store.

After that, the store-side communication device 70 executes the authentication process. In the authentication process, first, the store-side communication device 70 transmits the first authentication signal M201 to the vehicle-mounted communication device 50 through the embedded electrode 73. The communication at this time is performed by direct communication between the buried electrode 73 and the vehicle electrode 54. As a result, the in-vehicle communication device 50 authenticates the store-side communication device 70. After that, the vehicle-mounted communication device 50 transmits the second authentication signal M202 to each mobile terminal 60. As a result, each mobile terminal 60 authenticates the in-vehicle communication device 50 and the store-side communication device 70. Then, each mobile terminal 60 transmits a third authentication signal M203 to the in-vehicle communication device 50. As a result, the in-vehicle communication device 50 authenticates each mobile terminal 60. The communication between the in-vehicle communication device 50 and each mobile terminal 60 is performed by human body communication via the occupant J. After that, the vehicle-mounted communication device 50 transmits the fourth authentication signal M204 to the store-side communication device 70 through the embedded electrode 73. As a result, the store-side communication device 70 authenticates the in-vehicle communication device 50 and each mobile terminal 60. By transmitting and receiving each of these authentication signals, mutual authentication between the in-vehicle communication device 50, the first mobile terminal 60A, the second mobile terminal 60B, and the store-side communication device 70 is completed.

When the detection and authentication process is completed, the store-side communication device 70 executes the occupant information collection process for collecting the information of the occupant J on board the vehicle 200 (S801). In the occupant information collection process, the store-side communication device 70 transmits the personal information request signal M300 to the vehicle-mounted communication device 50. The personal information request signal M300 is a signal that requests the mobile terminal 60 that has received the signal to transmit the personal information recorded in the recording unit 66 to the store-side communication device 70. Upon receiving the personal information request signal M300, the in-vehicle communication device 50 transmits the personal information request signal M300 to each mobile terminal 60. Each mobile terminal 60 performs response processing based on the personal information request signal M300 (step S802).

In the response process, each mobile terminal 60 transmits a personal information signal M 301 including personal information (age, gender, family structure, etc.) recorded in advance in the recording unit 66 to the vehicle-mounted communication device 50. The in-vehicle communication device 50 transmits the personal information signal M301 received from each mobile terminal 60 to the store-side communication device 70. The store-side communication device 70 grasps the information of the occupant J in the vehicle 200 that has entered the store by receiving the personal information signal M301 of each mobile terminal 60 transmitted from the in-vehicle communication device 50 (step S803).

When the store-side communication device 70 grasps the personal information of each mobile terminal 60, the store display unit 74 displays the occupant information (step S804). As a result, the clerk grasps the information of the occupant J between the time when the vehicle 200 enters the store and the time when the vehicle arrives in front of the building 411. When the clerk grasps the personal information of each mobile terminal 60, the clerk starts the preparation for welcoming the occupant J before the vehicle 200 arrives in front of the building 411 (step S805). For example, when the personal information of each mobile terminal 60 includes a family structure with children, the clerk prepares a table set or a stroller including sweets and toys for children in advance. In addition, the clerk cleans up the table near the kids space in the building 411 and prepares the occupant J so that he can guide him. In addition, for example, when the personal information of each mobile terminal 60 includes that the person is an elderly person, the clerk prepares a wheelchair and prepares a table seat that can be guided by a stepless route in the building 411. do. When the clerk is ready to meet, he leaves the building 411 and waits in front of the entrance 411B, waiting for the arrival of the vehicle 200. Then, when the vehicle 200 enters the stop line 413 and stops (step S806), the occupant J is guided into the building 411. After that, the key of the vehicle 200 is kept from the occupant J, the vehicle 200 is moved, and services such as inspection are performed (step S807).

As described above, in the present embodiment, the vehicle electrode 54 and the buried electrode 73 are connected when the vehicle 200 passes over the buried electrode 73. This enables direct wireless communication between the vehicle-mounted communication device 50 and the store-side communication device 70 when the vehicle 200 is passing over the buried electrode 73. Therefore, in the store-side communication device 70, the embedded electrode 73 corresponds to the second external electrode, and the area on the embedded electrode 73 is a predetermined communication range.

Then, based on this information, the clerk can start preparing for pick-up in advance before the vehicle 200 arrives. Therefore, when the vehicle 200 arrives at the building 411, it becomes possible to promptly develop a service tailored to the occupant J. Therefore, it can also contribute to improving the quality of the service provided from the store 410 to the occupant J.

The third control unit 171 of the store-side communication device 170 stores the identification information of the authenticated in-vehicle communication device 150.

When the warehousing vehicle detection authentication process is completed, the store-side communication device 170 executes the occupant information collection process for collecting the information of the occupant J on board the vehicle 200 (step S1201). In the occupant information collection process, the store-side communication device 170 transmits the personal information request signal M300 to the vehicle-mounted communication device 150. The personal information request signal M300 is a signal that requests the mobile terminal 160 that has received the signal to transmit the personal information recorded in the recording unit 26 to the store-side communication device 170. Upon receiving the personal information request signal M300, the in-vehicle communication device 150 transmits the personal information request signal M300 to each mobile terminal 160. Each mobile terminal 160 performs response processing based on the personal information request signal M300 (step S1202).

In the response process, each mobile terminal 160 transmits a personal information signal M 301 including personal information (age, gender, etc.) recorded in advance in the recording unit 26 to the in-vehicle communication device 150. The in-vehicle communication device 150 transmits the personal information signal M301 received from each mobile terminal 160 to the store-side communication device 170. The store-side communication device 170 grasps the information of the occupant J in the warehousing vehicle 200 by receiving the personal information signal M301 of each mobile terminal 160 transmitted from the vehicle-mounted communication device 150 (step S1203).

When the personal information of the mobile terminal 160 is grasped in the store-side communication device 170, the parking position selection unit 178 selects the parking position of the vehicle 200 (step S1204). The parking position selection unit 178 first detects an empty parking space in the parking lot 422 where the vehicle 200 is not stopped, based on the output signal from the parking state determination unit 177. Then, the optimum parking position is selected from the vacant parking spaces based on the personal information of the mobile terminal 160. When the personal information of the mobile terminal 160 includes the elderly, the parking position selection unit 178 sets the parking space closest to the building 421 among the vacant parking spaces in the area A as the parking position. Select. When the parking position selection unit 178 selects the parking position, the third control unit 171 of the store-side communication device 170 displays an image showing the parking position on the display unit 176 (step S1205).

As shown in FIG. 13, in this process, the third control unit 171 shows a plan view of the parking lot 422 as an image showing the parking position on the display unit 176. In this plan view, the selected parking position is surrounded by a broken line frame, and the route from the entrance / exit portion 422A of the parking lot 422 is indicated by an arrow. The parking space in which another vehicle 200 is already parked is displayed in a filled state.

Further, the store-side communication device 170 transmits a parking position signal M1200 including parking position information to each mobile terminal 160 via the in-vehicle communication device 150. When each mobile terminal 160 receives the parking position signal M1200, the second control unit 21 activates the parking lot entry / exit application and causes the mobile display unit 25 to display a similar image indicating the parking position (step S1206). After that, the store-side communication device 170 performs an opening operation of rotating the first rotation bar 423B upward by the rotation bar drive unit 179 (step S1207), and the vehicle is moved from the voice guidance unit 175 to the parking position for the occupant J. Guidance is performed by automatic voice so as to move 200 (step S1208). According to this guidance, the occupant J moves the vehicle 200 stopped in front of the first rotation bar 423B to the parking position (step S1209). After notifying that the vehicle 200 is to be moved, the store-side communication device 170 confirms that the vehicle 200 has passed below the first rotation bar 423B, and the rotation bar drive unit 179 makes the first rotation. The closing operation of rotating the bar 423B downward is performed (step S1210).

Further, as shown in FIG. 14, the store-side communication device 170 detects the vehicle 200 leaving the store 420, and mutually authenticates the vehicle-mounted communication device 150 of the vehicle 200 and the mobile terminal 160 possessed by the occupant J. (Step S1400). In this process, the same process as the above-mentioned warehousing vehicle detection authentication process is executed. That is, in the delivery vehicle detection authentication process, the third control unit 171 first generates the response request signal M100. The third control unit 171 outputs the response request signal M100 to the third communication unit 172 at predetermined time intervals. The third communication unit 172 transmits a response request signal M100 from the outlet embedded electrode 174 based on the output signal from the third control unit 171. If there is no vehicle 200 stopped in front of the second rotation bar 423C, the response request signal M100 is not returned even if the response request signal M100 is transmitted from the outlet embedded electrode 174. Therefore, the third control unit 171 determines that there is no vehicle 200 to leave when there is no input of the response signal M101 from the outlet buried electrode 174.

On the other hand, when there is a vehicle 200 stopped in front of the second rotating bar 423C, the vehicle electrode 54 provided on the floor portion 202 of the vehicle 200 and the outlet buried electrode 174 are arranged in close proximity to each other. Will be done. Therefore, the vehicle electrode 54 and the outlet embedded electrode 174 are in a state of being wirelessly connected to each other, and are in a state of being capable of direct communication without going through an external communication network such as wireless. In this state, when the response request signal M100 is transmitted from the outlet embedded electrode 174, the response request signal M100 is transmitted to the first communication unit 52 through the vehicle electrode 54. The first communication unit 52 outputs the received response request signal M100 to the first control unit 51. The first control unit 51 generates a response signal M101 for the received response request signal M100 and performs a response process to output the response signal M101 to the first communication unit 52. The first communication unit 52 transmits a response signal M101 from the vehicle electrode 54 based on the output signal from the first control unit 51. The store-side communication device 170 detects the vehicle 200 that is about to leave the warehouse by receiving the response signal M101 by the outlet buried electrode 174.

After that, the store-side communication device 170 executes an authentication process to complete mutual authentication between the in-vehicle communication device 150, the first mobile terminal 160A, the second mobile terminal 160B, and the store-side communication device 170. The third control unit 171 of the store-side communication device 170 stores the identification information of the in-vehicle communication device 150 authenticated at the time of warehousing. When the vehicle 200 leaves the warehouse, the store-side communication device 170 performs payment processing using the identification information (step S1401). That is, the third control unit 171 calculates, for example, the usage time from warehousing to warehousing based on the identification information, and calculates the usage fee. Then, the third control unit 171 generates a payment signal M1400 including information such as the calculated usage fee and the payee thereof. When the third control unit 171 outputs the settlement signal M1400 to the third communication unit 172, the third communication unit 172 makes a settlement from the outlet embedded electrode 174 to each mobile terminal 160 based on the output signal from the third control unit 171. The signal M1400 is transmitted.

Upon receiving the payment signal M1400 on each mobile terminal 160, the second control unit 21 activates the parking lot entry / exit application to display the waiting for payment. When the occupant J performs an operation for performing payment processing on any of the mobile terminals 160, the second control unit 21 controls the electronic payment unit 27 to perform electronic payment processing by a well-known method (). Step S1402). As a result, the settlement is completed without the crew member J performing an act such as inserting money at the gate 423.

After that, the store-side communication device 170 performs an opening operation of rotating the second rotation bar 423C upward by the rotation bar drive unit 179 (step S1403), and leaves the vehicle 200 from the voice guidance unit 175 to the occupant J. Guidance is performed by automatic voice so as to be performed (step S1404). According to this guidance, the occupant J moves the vehicle 200 stopped in front of the second rotating bar 423C and leaves the garage (step S1405). After notifying that the vehicle 200 is to be moved, the store-side communication device 170 confirms that the vehicle 200 has passed below the second rotation bar 423C, and the rotation bar drive unit 179 makes the second rotation. The closing operation of rotating the bar 423C downward is performed (step S1406).

As described above, in the present embodiment, when the vehicle 200 is stopped in front of the first rotation bar 423B, the inlet embedded electrode 173 and the vehicle electrode 54 are connected, and the vehicle 200 is in front of the second rotation bar 423C. When stopped at, the outlet buried electrode 174 and the vehicle electrode 54 are connected. As a result, direct wireless communication is possible between the in-vehicle communication device 150 and the store-side communication device 170 both before entering and leaving the vehicle 200. In the present embodiment, in the store-side communication device 170, the inlet embedded electrode 173 and the outlet embedded electrode 174 correspond to the second external electrode, and are located in front of the first rotation bar 423B and in front of the second rotation bar 423C. Is the predetermined communication range.

According to the third embodiment, in addition to the same effects as in (1) to (3) and (5) above, the following effects can be obtained.
(7) When the personal information of the mobile terminal 160 includes the elderly, the parking position selection unit 178 selects the parking space closest to the building 421 among the vacant parking spaces in the area A. Select as a parking position. As a result, when the vehicle 200 enters the parking lot 422, it is possible to develop a service tailored to the occupant J based on the personal information of the mobile terminal 160. Therefore, it can also contribute to improving the quality of the service provided from the store 420 to the occupant J.

(8) The store-side communication device 170 causes each mobile terminal 160 to display an image indicating the parking position. Therefore, the occupant J can grasp the parking position through the mobile display unit 25 of the mobile terminal 160 not only while the vehicle is stopped at the gate 423 but also after passing through the gate 423 and moving into the parking lot 422. ..

The above-mentioned third embodiment can also be carried out in the following embodiments in which the above-mentioned third embodiment is appropriately modified.
-As personal information to be recorded in advance in the mobile terminal 160, information on whether or not the patient is pregnant or information on whether or not the person is disabled may be recorded. In this case, the parking position selection unit 178 can select the parking space closest to the building 421 among the parking spaces as the parking position even when the occupant J includes a pregnant woman or a handicapped person. Further, as personal information to be recorded in advance in the mobile terminal 160, information on whether or not a large load is loaded on the vehicle 200 may be recorded. In this case, the parking position selection unit 178 may select a parking space close to the building 421 in which the vehicle 200 is not stopped as a parking position in order to unload the luggage.

-Although the example in which the parking lot 422 is divided into two parking areas is shown, the parking area may be further divided. For example, not only due to the difference in the distance to the building 421, but also due to the difference in the size of the parking space, such as providing an area where the parking space is widely set for people with disabilities and for loading and unloading large cargo. Areas may be divided. By setting the parking area in detail, it becomes possible to select a more appropriate parking position based on the personal information of the occupant J. It is also possible to set the parking position in units of parking spaces without dividing the parking lot 422 into parking areas.

-The method of notifying the occupant J of the parking position is not limited to the above. For example, an image indicating the parking position may be displayed on only one of the mobile display unit 25 of the mobile terminal 160 and the display unit 176 of the store-side communication device 170. Further, it is also possible to further provide a display unit as a configuration of the vehicle-mounted communication device 50 and display an image indicating the parking position on the display unit of the vehicle-mounted communication device 50. In addition to the configuration in which the in-vehicle communication device 50 is provided with the display unit, it is also possible to configure the display unit of the car navigation device mounted on the vehicle 200. Further, the method of displaying an image is not limited, and the parking position may be notified by voice. For example, it is possible to notify the occupant J of the parking position by assigning an individual symbol to the parking space and transmitting the symbol indicating the parking position by voice. It should be noted that such a configuration can be realized by a voice unit provided in at least one of the in-vehicle communication device 50, the mobile terminal 160, and the store-side communication device 170.

-The parking state determination unit 177 does not have to be a camera. For example, a vehicle detection sensor may be provided in each parking space so that the third control unit 171 determines the parking state of each parking space based on the output signal from each vehicle detection sensor. In this case, the third control unit 171 also functions as a parking state determination unit. Further, in the store-side communication device 170, the parking position information selected at the time of warehousing is stored in association with the identification information of the vehicle 200, and the identification information of the vehicle 200 leaving the parking lot is collated to each parking. It is also possible to determine the current parking situation in the space.

The burying range of the inlet buried electrode 173 and the outlet buried electrode 174 is not limited to a range that exceeds the length in the width direction and the front-rear direction of the vehicle 200. For example, the buried range of the inlet buried electrode 173 may not exceed the length in the width direction and the front-rear direction of the vehicle 200. Even in such a case, by burying the inlet buried electrode 173 in a range facing the vehicle 200 stopped in front of the first rotation bar 423B, the vehicle electrode 54 and the entrance buried electrode 173 are wirelessly communicated with each other. It can be connected. The same applies to the outlet buried electrode 174.

-The mode of payment processing can be changed as appropriate. For example, instead of transmitting the payment signal M1400 to all of the mobile terminals 160, the payment signal M1400 may be transmitted to any one of the mobile terminals 160. In this case, it is possible to complete the electronic payment by using the receipt of the payment signal M1400 as a trigger without the operation of the occupant J. In this case, personal information includes information on whether or not the mobile terminal 160 is a payable mobile terminal 160 and is registered in advance in the recording unit 26 of the mobile terminal 160. Then, the store-side communication device 170 may select the mobile terminal 160 that transmits the payment signal M1400 based on the personal information transmitted from each mobile terminal 160.

-It is also possible to omit the payment process. In this case, when the vehicle 200 stops in front of the second rotation bar 423C, the store-side communication device 170 displays the usage fee on the display unit 176, and the occupant J directly sends money to the money input unit of the gate 423. You only have to pay the usage fee by putting it in.

-The mode in which when the first rotation bar 423B and the second rotation bar 423C are rotated, the voice guidance unit 175 automatically guides the occupant J to enter and leave the vehicle 200 is shown. Guidance when occupying and leaving the vehicle 200 to the occupant J is not limited to automatic voice. For example, a specific buzzer sound may be sounded. Further, when the first rotation bar 423B and the second rotation bar 423C are rotated, it is not necessary to perform guidance such as voice guidance.

-As an example of the parking lot entry / exit service, the case where there is a building 421 in the neighborhood was explained, but the parking lot entry / exit service can also be used for an hourly rental parking lot (coin parking) where there is no building 421 in the neighborhood. be.

Each of the above embodiments can be modified and implemented as follows. The following modification examples can also be implemented in appropriate combinations with each other.
The first communication units 12, 52 are designed to output all received signals to the first control units 11, 51, but the configuration of the first communication units 12, 52 is not limited to this. For example, the first communication units 12, 52 output signals received from the mobile terminals 20, 60, 160 to the store-side communication devices 30, 70, 170 to the first control units 11, 51. Instead, it may be output to the vehicle electrodes 14 and 54 as it is. Further, the first communication units 12, 52 output signals received from the store-side communication devices 30, 70, 170 to the mobile terminals 20, 60, 160 to the first control units 11, 51. Instead, it may be output to the first human body coupling electrodes 13 and 53 as it is.

In the in-vehicle communication devices 10 and 50, the arrangement of the first control units 11, 51, the first communication units 12, 52, and the window opening / closing unit 15 can be appropriately changed. For example, at least one of the first control unit 11, the first communication unit 12, and the window opening / closing unit 15 may be arranged in the vehicle interior 201. Further, although the first human body coupling electrodes 13 and 53 are embedded in the seat portion 203A of the driver's seat 203, the seat portion of the passenger seat (not shown), and the seat portion 204A of the rear seat 204, they may be provided at other positions. For example, the first human body coupling electrodes 13 and 53 can be provided on the backrests of the driver's seat 203, the passenger seat, and the rear seat 204, or on the floor of the passenger compartment 201. Even with such a configuration, it is possible to connect the first human body coupling electrodes 13 and 53 to the occupant J.

-Vehicle electrodes 14 and 54 were connected by wire to the first communication units 12 and 52, and these could be connected without going through other devices. Instead of such a configuration, it is also possible to communicate between the first communication units 12, 52 and the vehicle electrodes 14, 54 by human body communication via the occupant J. For example, when the first communication units 12, 52 and the vehicle electrodes 14, 54 are arranged apart from each other, the first communication units 12, 52 and the vehicle can be connected by connecting them using human body communication. Wiring connecting the electrodes 14 and 54 can be omitted.

-It is also possible to add the function of the first external electrode to the tire or door panel of the vehicle 200. As a configuration for adding the function of the first external electrode to the tire, for example, the configuration shown in FIG. 15 can be adopted. In the configuration shown in FIG. 15, the same configurations as those in the first embodiment are designated by common reference numerals and the description thereof will be omitted.

As shown in FIG. 15, the vehicle 200 has tires 206. The tire 206 is made of, for example, rubber, and an annular steel belt 207 made of metal is provided inside the tire 206. The tire 206 is made of rubber and has a property of not allowing a current to flow, but has a property of acting as a dielectric when a high frequency current is supplied. The first communication unit 12 is configured to be able to supply, for example, a high frequency current in the megahertz band to the tire, and causes the tire 206 to function as a first external electrode for communicating with the outside. Further, a first embedded electrode 33 as a second external electrode of the store-side communication device 30 is embedded in the travel path 402 of the store 400. In this configuration, since the tire 206 functioning as the first external electrode and the traveling path 402 in which the first embedded electrode 33 is embedded are in direct contact with each other, these distances can be made appropriately close to each other. Then, by supplying a high-frequency current from the first communication unit 12 to the tire 206, the tire 206 and the first embedded electrode 33 are connected as shown by arrows in FIG. 15, and the in-vehicle communication device 10 and the store-side communication device 30 are connected. And can be in a state where direct communication is possible without going through an external communication network such as wireless. Therefore, when the vehicle 200 travels at a specific position on the traveling path 402 of the store 400, the first external electrode and the second external electrode can be connected to each other so that direct communication is possible. Interference from the outside can be further suppressed in the communication path between the external electrode and the second external electrode.

When the function of the first external electrode is added to the door panel, the first communication unit 12 radiates radio waves in the frequency band used for short-range communication from the door panel. In this case, the second external electrode is provided in the device arranged at the position facing the door panel in the store. As a result, it is possible to realize a state in which the door panel functioning as the first external electrode and the second external electrode face each other and can directly communicate with each other.

-Although the predetermined communication range in the store-side communication devices 30, 70, 170 has been set in a part of the travel path 402, 412 and the parking lot 422, the setting mode of the predetermined communication range is not limited to these. For example, by burying the second external electrode over the entire building and the traveling path, it is possible to set the entire site of the store as a predetermined communication range. In addition, if the communicable distance of the second external electrode is appropriate, the second external electrode may be placed at a specific location within the store premises so that the entire store premises are within the predetermined communication range. It is possible.

-As the mobile terminals 20, 60, 160, it is also possible to adopt a terminal that does not have the mobile operation units 24, 64 or the mobile display units 25, 65, such as an electronic key of a vehicle. In this case, if personal information is registered in the mobile terminal in advance by a dedicated machine, the personal information can be transmitted from the mobile terminal to the store-side communication devices 30, 70, 170.

-Although the example in which the number of occupants J on the vehicle 200 is two has been described, the number of occupants J may be one or three or more. Even in such a case, the same service as in each of the above embodiments can be provided.

-Even if all the occupants J on board the vehicle 200 do not have a mobile terminal, it is possible to configure a system similar to the vehicle communication system described above. That is, even if the number of occupants J and the number of mobile terminals are different, if the information of other occupants is registered in the mobile terminal, a system similar to the above-mentioned vehicle communication system can be configured. Can be done.
