FIG. 2 is a diagram showing an example of the operation of the vehicle data communication system according to the first embodiment. Next, the operation and action of the vehicle data communication system according to the first embodiment will be described with reference to FIG. Here, the case where data is transmitted and received using the vehicle-mounted device 2 will be considered. First, the user carries his / her own mobile communication terminal 3 (it may be carried in a bag or the like) into the vehicle 1. At this time, the mobile communication terminal 3 and the vehicle-mounted device 2 such as a car navigation device are equipped with wireless communication means such as Bluetooth (Bluetooth), and for example, the user pulls a door knob of the vehicle 1 or turns on an ignition switch. In case of doing, a trigger is applied, and the in-vehicle device 2 causes the mobile communication terminal 3
The search for whether is in the car starts. When the mobile communication terminal 3 is found in the vehicle by this operation, a wireless link is formed between the vehicle-mounted device 2 and the mobile communication terminal 3 and a standby state in which data communication is possible is achieved.
There will be a plurality of communication terminals capable of transmitting and receiving data. The search operation of the mobile communication terminal 3 may be performed during data transmission / reception, and in that case, the following operation is appropriately interrupted. Next, the user executes the request using the command input unit 27 of the vehicle-mounted apparatus 2 (see FIG. 1 below). At this time, the in-vehicle device 2 temporarily holds the request, and the communication terminal list database 26 does not currently use the communication terminals (the in-vehicle communication terminal 6 and the mobile communication terminal 3 such as a mobile phone. The same applies hereinafter). Search for. The inside of the vehicle-mounted device 2 operates according to an algorithm that preferentially uses a communication terminal that is not currently used, and data transmission / reception is basically performed using a communication terminal that is not used. It has become. If there is no communication terminal that is not currently used, use a communication terminal with a light communication load or wait until the use of another communication terminal is completed. Further, inside the in-vehicle apparatus 2, the data division means 24 and the data synthesizing means 25 determine the data division size in consideration of the throughput of each communication terminal found by the communication terminal list database 26, and divide the data. I do. At the same time, a label indicating the order is attached to the divided data so that the order in which the data are arranged can be understood. When transmission / reception of one divided data is completed, the vacant slot is used for transmission / reception of the next divided data. The divided data are transmitted and received via a plurality of communication terminals, and the data synthesizing means 25 refers to the label to synthesize the data into one data. If the data communication is interrupted due to battery exhaustion, etc., while the data communication is being performed halfway, the divided data is restored to the original data again and the communication terminal currently having the wireless link is used. Data communication will be performed again. The request actually transmitted is composed of a sender ID, a receivable communication terminal ID, and a request command. Here, the receivable communication terminal ID can be searched using the communication terminal list database 26. As described above, the server 5 uses the ID storage area 5

What action to perform on the data in is determined. An ID storage area 51 is set for each data, and a transmission source ID and a receivable communication terminal ID are stored. Since the communication terminals that can be transmitted and received change dynamically due to events such as electric field strength and handover, when transmission and reception are possible, transmission and reception can be currently performed by returning the communication terminal ID that can be transmitted and received to the server 5. Informs the server 5 that When the server 5 transmits data to the in-vehicle device 2, the communication terminal ID of the receivable communication terminal is used to determine the communication terminal of the reception destination, the ACK is returned to the transmission source ID, and the divided data is transmitted to each reception destination. To send. Further, since it is possible to confirm the carrier of each communication terminal, the electric field strength, the communication rate, and the like by the communication terminal list database 26, it is possible to define the optimum data division size, and the communication charge, It can be a great advantage due to the time required for transmission and reception. In this way, the divided and transmitted data is combined into one data by the data combining means 25 in the vehicle-mounted device 2.

It is possible. In addition, the in-vehicle device 2
Is currently available in-vehicle communication terminal 6 and mobile communication terminal 3
By having the communication terminal list database 26 of

FIGS. 3A and 3B are flowcharts of the operation of the vehicle data communication system according to the first embodiment. Next, the details of the control of the first embodiment will be described with reference to FIG.
Description will be given along the flowcharts of (a) and (b). The flowchart of FIG. 3A shows the flow until the server 5 accepts the request from the user, and the flowchart of FIG. 3B shows that the in-vehicle apparatus 2 receives the data sent from the server 5. It shows the flow up to. Note that S111 to S120 in FIG.

18 is S11 for the operation of transmitting the request data.
9 to S120 correspond to an operation for receiving request data in the server 5. First, S11
In 1, the command input unit 27 of the in-vehicle apparatus 2 sends a request for data acquisition to the server 5. For example, a method of selecting a button corresponding to a request appearing on the monitor by using a remote controller or a touch panel of the vehicle-mounted car navigation device and voice recognition can be considered. The fact that the request has been recognized by the vehicle-mounted device 2 can be notified to the user by indicating a beep sound or that the request has been recognized on the screen. In S112, the mobile communication terminal 3 brought into the vehicle 1 is searched. The user puts the mobile communication terminal 3 in a pocket of a bag or pants and gets in the vehicle 1. As described above, the door knob of the vehicle 1, the switch for detecting the opening / closing of the door, or the ignition switch is provided with a trigger switch for issuing a Bluetooth inquiry, and the user pulls the door knob or turns on the ignition switch. As a result, the search for the mobile communication terminal 3 brought into the vehicle 1 starts. The data (model name, business operator, communication rate, etc.) of the mobile communication terminal 3 found by the search is the communication terminal list database 26 in the vehicle-mounted device 2.

To form a wireless link. Since this vehicle data communication system basically handles data, B1uetooth
The ACL link (the connection method required when handling data) according to the above is sufficient, but the SCO link (the connection method required when handling voice) may be formed as needed. In S114, after the wireless link is formed, or the mobile communication terminal 3 is searched, and if the mobile communication terminal 3 cannot be found, the communication terminal list database 26 grasps the status of the communication terminal. As described above, the communication terminal list database 26 stores the data (model name, business operator, communication rate, etc.) of the communication terminals connected to the in-vehicle apparatus 2, and the current usage status and communication You can know if the terminal is connected. In S115, S
The optimum data division size is calculated for the communication terminal found in 114. Since the communication rate and the communication method differ depending on the communication terminal, it is necessary to calculate the optimum data division size for each communication terminal. By performing this calculation, it is possible to perform efficient communication. In S116, the request command temporarily stored in the vehicle-mounted apparatus 2 is divided. A request command based on the division size calculated in S115 and temporarily stored in the vehicle-mounted apparatus 2 is cut out from the request commands. At the same time, each segmented data is labeled to define the order of the segmented data. In S117, the divided data cut out in S116 is transmitted to the server 5.
At this time, each communication terminal has a transmission source ID, and all divided data can be treated as if they were sent from the same transmission source in a pseudo manner. S1
At 18, it is checked whether the divided data sent earlier corresponds to the last one. If it is not the last one, the operations from S112 to S117 are performed again. In S119, the server 5 side receives, rearranges, and combines the divided data. Pseudo-identical communication terminals (actually different communication terminals, but the same source I
The divided data transmitted by (which has D and is recognized as the same communication terminal on the server 5 side) is
It is received by the server 5 as divided data sent from the same communication terminal. The data combining means 54 of the server 5 sorts the divided data in the order of labels, and the divided data is combined with the original data. In S120, various ID data are extracted from the data synthesized in S119 and stored in the ID storage area 52 corresponding to the data in the server 5 which has accepted the request. As described above, the various IDs are composed of the sender ID and the receivable communication terminal ID, and are used to identify the communication terminal. In addition, FIG.
The control shown in S121 to S129 corresponds to the operation in which the vehicle-mounted device 2 receives the data from the server 5 via the communication terminal. However, with regard to S122 to S129, S111 to S119 shown in FIG. The same operation is performed.

Second Embodiment FIG. 4 is a diagram showing the configuration of a vehicle data communication system according to a second embodiment of the present invention. The configuration of the second embodiment is almost the same as that of the first embodiment, but as shown in FIG. 4, the in-vehicle device 2 internally has an electric field intensity map having an electric field intensity map indicating the communication quality of the communication terminal. Database 28
And a calculation means 29 for calculating the division size of the data.

Next, the operation of the second embodiment will be described. FIG. 5 is a diagram showing an example of the electric field intensity map of the second embodiment.

For example, consider a case where data is transmitted / received using the vehicle-mounted device 2 (FIG. 4) having communication quality data of the communication terminal such as the electric field strength map shown in FIG. Since the processing of most of the basic parts is the same as that of the first embodiment, only the method of determining the data division size will be described here. In the system according to the second embodiment,
The data division size is determined mainly in consideration of the throughput of each communication terminal, etc., but in the second embodiment, the vehicle-mounted device 2 divides the data into the electric field intensity database 28 having the electric field intensity map and the like. Since the calculation means 29 for calculating the size is provided, it is possible to pre-read the electric field strength data, calculate and determine the division size of the data in consideration of the future electric field strength situation, and perform data communication. . For example, in the first embodiment, it is possible to roughly determine the division size of data according to the data (model name, business operator, communication rate, etc.) of the communication terminal,
In addition, it is possible to grasp the situation such as a change in the electric field strength from the communication quality data, calculate the influence on the communication rate by the calculation means 29, and determine the optimum data division size. At this time, it is necessary to calculate the data division size in consideration of the data division time which becomes the overhead. FIG. 6 is a diagram illustrating a method of determining the data division size. Since the data communication rate differs depending on the business operator, the communication method, etc., there are various methods for setting the data division size. The default data division size 4 shown in FIG. 6 indicates the default data division size in the state where the electric field strength is the best, and the default data division size is calculated using the communication rate v4 and the communication time t announced by the operator. 4 = v4 × t ..., which is the maximum value (predicted value) of the amount of data that can be used for data communication during the communication time t. However, the communication time t is a general legal speed of the vehicle (for example, 5
It is the time when the vehicle runs a unit distance corresponding to the electric field strength mesh at 0 km / h). Therefore, in the communication terminals A and B,
The default data division size 4 is different. Also,
The same applies to the default data division sizes 1 to 3, by using the communication rates v1 to v3 in each electric field strength, the default data division size 1 = v1 × t ... Default data division size 2 = v2 × t ... Default It can be expressed as the data division size 3 = v3 × t. This is, of course, the maximum amount of data that can be communicated in each electric field strength during the time t.

As described above, in the second embodiment, the vehicle-mounted device 2 uses the electric field strength database 28, which is a communication status database showing the communication status of the communication terminal 3, and the communication terminal 6 based on the data. 3 is included in the calculation means 29 for calculating the data division size, and the optimum data division size (allocation ratio) to the plurality of communication terminals 6 and 3 is calculated using the data. It is possible to secure. In addition, when there are mobile communication terminals 3 of a plurality of carriers, the electric field strength maps are completely different, so that it is possible to perform more stable communication by complementing each other.

FIGS. 7A and 7B are flowcharts of the operation of the vehicle data communication system according to the second embodiment. Next, FIG. 7 shows details of the control of the second embodiment.

The flowchart of FIG. 7A shows the flow until the server 5 receives the request from the user.
The flowchart of (b) shows the flow until the vehicle-mounted device 2 receives the data sent from the server 5. The steps of searching for the mobile communication terminal, forming the wireless link, and grasping the usage status of the communication terminal shown in S111 to S114 are the same as those in the flowchart of FIG. Further, the steps of transmitting the request data shown in S117 to S118, and S119 to S1.
The steps for receiving request data in the server 5 shown in 20 are the same as those in the flowchart of FIG.

In step S111, the electric field intensity data corresponding to the future traveling route is read from the electric field intensity map of the electric field intensity database 28 provided in the vehicle-mounted device 2 (FIG. 4). In S112, the calculation unit 29 calculates the default data division size using the electric field intensity data read in S111. First, the average communication rate corresponding to each electric field strength level is calculated (or loaded from the memory in the vehicle-mounted apparatus 2). The default data division size is calculated by the product of this average communication rate and the expected time for passing through the mesh shown in the electric field strength map.
In S113, the request command temporarily stored in the vehicle-mounted communication terminal 6 is cut out and labeled with the default data division size determined in S112. Further, the control shown in FIG. 7B corresponds to the operation in which the vehicle-mounted apparatus 2 receives the data from the server 5 via the communication terminal, and other than S121, the control illustrated in FIG.
This is the same as the operation shown in (a). Further, since the server 5 cannot directly know the outline of the communication terminal connected to the vehicle-mounted apparatus 2, it is necessary to transmit the data of the communication terminal list database 26 from the vehicle-mounted apparatus 2 side to the server 5 side. As described above, in the second embodiment, when the vehicle-mounted device 2 is provided with the electric field strength map, it is possible to perform data communication in consideration of the influence of the communication rate due to the strength of the electric field strength on the traveling route. Is. As a result, it is possible to systematically perform data communication in consideration of the above-mentioned situation such as the electric field strength.

Third Embodiment FIG. 8 is a diagram showing the configuration of a vehicle data communication system according to a third embodiment of the present invention.

The moving means of the vehicle speed is calculated by the calculating means 29 from the electric field intensity data read out in S111, and the communication time (the time required to pass through the specific electric field intensity mesh) is estimated from the moving average. In S112, from the communication time and the communication rate corresponding to each electric field strength,
The corrected data division size is calculated. The communication rate corresponding to each electric field strength is stored in the vehicle-mounted device 2, and the corrected data division size is calculated by obtaining the product of the communication rate and the estimated communication time. In S113, the request command temporarily stored in the vehicle-mounted communication terminal 6 is cut out and labeled with the corrected data division size determined in S112. The control shown in FIG. 10B corresponds to the operation in which the vehicle-mounted apparatus 2 receives the data from the server 5 via the communication terminal, and except for S121, it is the same as the operation shown in FIG. 10B.
