DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a driver identification device and a driver identification program according to the present invention will be described in detail with reference to FIGS.
(1) Overview of the embodiment As shown in FIG. 1, the driver identification system is composed of a mobile terminal 10 such as a smartphone carried by a driver D, an on-board device 30 such as a drive recorder mounted in a vehicle V, and a driver identification device 50 of this embodiment, and the mobile terminal 10 and the on-board device 30 are configured to be connectable to the driver identification device 50 via various communication networks such as a mobile phone network.
Both the mobile terminal 10 and the vehicle-mounted device 30 are equipped with a GPS receiving device or the like, and are thus capable of acquiring their own position information (terminal position information, vehicle position information).
In this embodiment, the driver identification device 50 identifies driver D who carries the mobile terminal 10 as the driver of the vehicle V in which the on-board device 30 is installed when the terminal location information received from the mobile terminal 10 carried by driver D matches (within Nm) with the vehicle location information received from the on-board device 30 installed in the vehicle V.

A specific outline of the operation will now be described.
As shown in FIG. 1, in this driver identification system, first, a driver D carrying a mobile terminal 10 gets into a vehicle V (FIG. 1(a)).
Then, when the driver D turns on the ignition (hereinafter referred to as IG) of the vehicle V, the in-vehicle unit 30 starts up by receiving power from the vehicle V when the IG is turned on, and periodically acquires vehicle position information until the IG is turned off, and transmits the acquired vehicle position information and vehicle ID to the driver identification device 50 (Figure 1 (b)).
Here, the vehicle ID is an identification number assigned to the vehicle-mounted unit 30 when it is installed in the vehicle V, and is an identification number for identifying the vehicle-mounted unit 30, but since the vehicle-mounted unit 30 is installed in the vehicle V, it also functions as an identification number for the driver identification device 50 to identify the vehicle.

Meanwhile, the driver D in the vehicle V starts the terminal side processing program of his/her mobile terminal 10. Then, the mobile terminal 10 periodically acquires the terminal location information of its own device until it receives an end notification from the driver identification device 50, and transmits the terminal location information and the terminal ID to the driver identification device 50 ( FIG. 1( c)).
Here, the terminal ID is an identification number for identifying the mobile terminal 10, but since it is assumed that the mobile terminal 10 is exclusively used by the driver D, it also functions as an identification number for identifying the driver.

The driver identification device 50 sequentially stores the vehicle ID and vehicle position information (hereinafter referred to as vehicle position) received from each vehicle-mounted device 30 .
Then, when a terminal ID and terminal location information (hereinafter referred to as terminal location) is received from one mobile terminal 10, if there is only one vehicle receiving the vehicle location within a radius of Nm (e.g., 100 m) from the received terminal location, the vehicle (the vehicle equipped with the vehicle-mounted unit 30 with the vehicle ID) is linked to the driver D (the driver who owns the mobile terminal 10) and saved (Figure 1 (d)).
Thereafter, the driver identification device 50 transmits a request to stop the application to the mobile terminal 10, and the mobile terminal 10 that receives this request terminates the terminal-side processing program (FIG. 1(e)).
In this way, according to the driver identification system, by using an inexpensive vehicle-mounted device 30 and a mobile terminal 10, it is possible to identify the driver D of the vehicle V with high accuracy.

(2) Details of the embodiment Hereinafter, details of the driver identification device 50 of the present embodiment will be described, including other configurations that configure the driver identification system.
FIG. 2 shows the configuration of the mobile terminal 10.
The mobile terminal 10 may be a smartphone, tablet, or other portable terminal device that is configured with a computer system and has a communication function.
The mobile terminal 10 comprises a location information acquisition means 11, a data communication means 12, a control means 13, a timing means 14, a storage means 15, and other means.

The location information acquisition means 11 includes a GPS (Global Positioning System) (not shown), and receives signals from GPS satellites to calculate the location (X, Y coordinate values) of the device itself.
The location information acquisition means 11 acquires the terminal location information once every a seconds and stores it in a RAM (not shown). The interval a seconds for acquiring the terminal location information is set to 600 seconds (10 minutes) as a default value, but this value can be changed automatically based on an instruction from the driver identification device 50 to change the a seconds during communication, or by a screen operation by the user (driver D).

The data communication means 12 connects to various networks such as the Internet via wireless communication to transmit and receive data.
When a smartphone is used as the mobile terminal 10, data for calls and communications is sent and received.

The control means 13 is mainly composed of a CPU, ROM, and RAM, and executes various programs to perform various controls such as displaying various images, acquiring data, and transmitting data.
The control means 13 of this embodiment transmits the terminal position information acquired by the position information acquisition means 11 together with the terminal ID to the driver identification device 50 via the data communication means 12 .
The clock means 14 is a means for measuring time. The control means 13 monitors the passage of time by the clock means 14, and acquires the terminal location information by the location information acquisition means 11 every a seconds.

The storage unit 15 stores various programs and data such as terminal side processing programs and terminal IDs.
The terminal-side processing program stored in the storage means 15 may be stored in advance, or may be downloaded and stored from the driver identification device 50, a program providing server, or the like via the data communication means 12 by operation of the user (driver D). Address information for connecting to the driver identification device 50 is defined in the terminal-side processing program, and communication with the driver identification device 50 becomes possible by executing the program.
When the terminal-side processing program is executed for the first time, a registration process is performed between the driver D and the driver identification device 50 through operation of the driver D, and driver information regarding the driver D who possesses the mobile terminal 10 on which the terminal-side processing program is saved, such as the name of the driver D, the operating company he/she belongs to, gender, age, etc., is transmitted.
In this registration process, the terminal ID transmitted from the driver identification device 50 is received and stored in the storage means 15. Note that the terminal ID may be predefined in the downloaded terminal side processing program.
In addition, the terminal ID may be a unique identifiable number (e.g., IMEI (International Mobile Equipment Identity) or a telephone number) that is pre-defined in the mobile terminal 10, rather than a number assigned by the driver identification device 50.

Other means include a display screen for displaying various information, a touch panel arranged on the display screen and functioning as an input means, an audio output means, an imaging means, etc. (none of which are shown in the figure).

FIG. 3 shows the configuration of the vehicle-mounted device 30. As shown in FIG.
The vehicle-mounted device 30 is configured as a computer system. The vehicle-mounted device 30 is equipped with a communication function and is configured to be able to be installed in a vehicle. The vehicle-mounted device 30 of this embodiment is a drive recorder that captures and stores video of the front and/or rear of the vehicle, and in some cases, the interior of the vehicle.
The vehicle-mounted device 30 includes a location information acquisition means 31, a data communication means 32, a control means 33, a timing means 34, a storage means 35, and other means.

The vehicle-mounted device 30 is connected to an external power source P, and is configured to start and stop depending on whether or not power is being supplied from the power source P.
Specifically, the power is supplied via a power socket (a so-called cigarette lighter socket) provided in the vehicle, but the power may also be supplied by directly connecting to the wiring of the vehicle's ACC power supply (accessory power supply).

The location information acquisition means 31 includes a GPS (Global Positioning System) (not shown), and receives signals from GPS satellites to calculate the location (X, Y coordinate values) of the device itself.
The location information acquisition means 31 acquires vehicle location information at intervals of once per second and stores the information in a RAM (not shown). Note that the acquisition of vehicle location information may be configured to be changed based on an operation by a user (driver D) or an instruction from the driver identification device 50, with the default being every second.
In this embodiment, since a drive recorder is used as the vehicle-mounted device 30, the location information acquisition means 31 also serves as the location information acquisition means provided in the drive recorder.

The data communication means 32 connects to various networks such as the Internet via wireless communication to transmit and receive data.
The control means 33 is mainly composed of a CPU, ROM, and RAM, and executes various programs to perform various controls such as displaying various images, acquiring data, and transmitting data.
The control means 33 of this embodiment compiles the vehicle position information acquired by the position information acquisition means 31 every second and stored in the RAM, and transmits the collected information together with the vehicle ID every b seconds to the driver identification device 50 via the data communication means 32. Here, the interval b seconds for acquiring the vehicle position information is set to 30 seconds as a default value, so that 30 pieces of vehicle position information and vehicle IDs are transmitted to the driver identification device 50, but the value of b seconds can be changed automatically by the user (driver D) operating the screen and/or based on an instruction to change b seconds from the driver identification device 50 during communication.
The clock means 34 is a means for measuring time. The control means 33 monitors the passage of time by the clock means 34, and acquires the vehicle position information by the position information acquisition means 31 every b seconds.

The storage means 35 stores various programs such as the vehicle-mounted device side processing program and data.
In the case where a drive recorder is used as the vehicle-mounted device 30 as in this embodiment, a video captured by the image capturing means is also stored in the storage means 35. The video also includes the vehicle position information acquired by the position information acquiring means 31 and the date and time recorded by the timing means 34.
As other means, the vehicle-mounted device 30 is provided with a photographing means (not shown) for functioning as a drive recorder, etc. When a supply other than a drive recorder is used as the vehicle-mounted device 30, various means corresponding to the device are provided, and programs and data corresponding to the supply are stored in the storage means 35.

FIG. 4 shows the configuration of the driver identification device 50. As shown in FIG.
The driver identification device 50 is configured as a computer system, and uses a server or the like connected to various networks such as the Internet.
The driver identification device 50 includes a data communication means 51, a mobile terminal position information storage means 52, an in-vehicle device position information storage means 53, a control means 54, a vehicle information storage means 55, a driver information storage means 56, a linking storage means 57, and other means.

The data communication means 51 transmits and receives various data between multiple mobile terminals 10 and multiple vehicle-mounted devices 30 via a network such as the Internet. Specifically, it receives terminal location information and terminal IDs/vehicle IDs from the mobile terminals 10 and vehicle-mounted devices 30, and transmits a termination notification to the mobile terminals 10 for which linking (identification of the driver of the vehicle) has been completed, requesting the termination of any running apps.

The mobile terminal location information storage means 52 is a storage means for storing terminal location information and terminal IDs transmitted from a plurality of mobile terminals 10 connected to the Internet.
The vehicle-mounted device position information storage means 53 is a storage means for storing vehicle position information and vehicle IDs transmitted from a plurality of vehicle-mounted devices 30 connected to the Internet. Since the vehicle-mounted device 30 transmits vehicle position information and vehicle IDs every b seconds from when the vehicle ignition is turned on to when it is turned off, the vehicle-mounted device position information storage means 53 stores the vehicle position information received for each vehicle ID together.

The control means 54 is mainly composed of a CPU, ROM, and RAM, and executes various programs to perform various controls such as displaying various images, acquiring data, and transmitting data. In this embodiment, the control means 54 executes a driver identification processing program stored in a storage means (not shown) to link the driver D with the vehicle V.

The vehicle information storage means 55 stores vehicle-related information such as the number written on the license plate of each vehicle V (vehicle registration number written on the vehicle registration plate, vehicle number written on the vehicle number plate, etc.), vehicle model, operating company, etc., along with a vehicle ID for each of the multiple vehicles V (Va, Vb, Vc, ...).
The vehicle ID is received from the vehicle-mounted device 30 together with the vehicle location information, but since the vehicle-mounted device 30 is mounted on one of the vehicles V, the vehicle ID functions as vehicle identification information that identifies the vehicle-mounted device 30 as well as the vehicle V.
The vehicle ID and vehicle information in the vehicle information storage means 55 are stored when all of the vehicles of an operating company are registered at once before services using the driver identification system for each operating company are started, and when additional vehicles V are registered thereafter.

The driver information storage means 56 stores the terminal ID of the registered mobile terminal 10 and the driver information of the user (driver D) using that terminal ID (driver D's name, operating company to which he belongs, gender, age, etc.).
Regarding the terminal ID and driver information for each mobile terminal 10, when the terminal side processing program of the mobile terminal 10 is executed for the first time, the registration process is executed by the driver D's operation, and the contents entered at that time are saved.

The linking storage means 57 stores pairs of vehicle V and driver D that are identified and linked by the driver identification process described below. In this embodiment, the main process is to identify the driver D of the vehicle V, so the linking storage means 57 stores the linked vehicle V and driver D, but also stores vehicle position information from ignition on to off, which is periodically transmitted from the vehicle-mounted device 30, as a driving record of the vehicle V. Based on this storage, a ride record (see FIG. 10) described below is created.

Other means include other storage means (not shown), which stores, for example, a facility DB (database). This facility DB stores the names, addresses, and location coordinates of various locations such as buildings, public facilities, parking lots, and companies (including operating companies and their offices) as data used to create the ride record described below. For example, the departure point of vehicle V is searched for from the location coordinates first received from the onboard device 30 (vehicle V), and the name (or address if there is no name) is output as the ride record.

Next, the operation of the embodiment configured as above will be described.
Each operation described below is processed by the control means 13 of the mobile terminal 10, the control means 33 of the in-vehicle device 30, and the control means 54 of the driver identification device 50 executing the corresponding programs. Here, the mobile terminal 10, the in-vehicle device 30, and the driver identification device 50 each execute various programs, but the process of identifying the driver D of the vehicle V and linking the two will be described in this embodiment. For example, in the case of the in-vehicle device 30, the description of the part that captures and records images of the inside and outside of the vehicle as a drive recorder will be omitted.

FIG. 5 is a flowchart showing the operation of the vehicle-mounted device 30 in the vehicle-mounted device side process.
When the driver D gets into the vehicle V and turns on the ignition, the power source P is supplied from the vehicle V, the in-vehicle device 30 is turned on, and the control means 33 executes the in-vehicle device side processing program (step 31).
Next, the control means 33 receives the location information via the location information acquisition means 31, and transmits the received location information together with the vehicle ID as vehicle location information to the driver identification device 50 via the data communication means 32 once every b seconds (step 32).
That is, the control means 33 sequentially stores the vehicle position information acquired by the position information acquisition means 31 every second in the RAM, checks with the timing means 34 whether or not the elapsed time b seconds (=30 seconds) has elapsed, and if so, transmits the multiple vehicle position information and the vehicle ID stored in the RAM to the driver identification device 50. The multiple vehicle position information transmitted by the control means 33 is sequentially stored in the driver identification device 50 and used for identifying the driving route and determining the driving information, and the last vehicle position information among the multiple vehicle position information is used when determining whether or not the vehicle is present within a judgment circle S (see FIG. 9) described later.

Here, the elapsed time b seconds starts from the time when the vehicle position information is acquired for the first time after the vehicle-mounted device side processing program is executed, or from the time when the vehicle position information and the vehicle ID are transmitted the previous time.
In addition, when the vehicle position information is acquired for the first time after the vehicle-mounted device side processing program is executed, the acquired vehicle position information and the vehicle ID may be immediately transmitted to the driver identification device 50 .

Thereafter, the control means 33 judges whether the ignition has been turned off or not based on the presence or absence of the supply of the power source P (step 33).
If the ignition is not turned off (step 33; N), the control means 33 returns to step 32 and continues transmission (transmission of vehicle position information and vehicle ID to the driver identification device 50) once every b seconds.
On the other hand, if the ignition is turned off (step 33; Y), the control means 33 ends the in-vehicle device side processing.

FIG. 6 is a flowchart showing the operation of terminal side processing by the mobile terminal 10.
FIG. 7 is an explanatory diagram showing the display screen of the mobile terminal in the terminal side processing.
The control means 13 of the mobile terminal 10 starts a terminal application (terminal side processing program) (step 11).
That is, after or before turning on the ignition of the vehicle V, when the driver D taps the startup icon 18 displayed on the display screen 17 of the mobile terminal 10 shown in Figure 7 (a), the control means 13 detects the tap and starts the terminal-side processing program in the memory means 15.

Next, the control means 13 receives the location information once every a seconds using the location information acquisition means 11, and transmits the received location information as terminal location information together with the terminal ID from the data communication means 12 to the driver identification device 50 (step 12). Here, a seconds is 600 seconds (=10 minutes) if it has not been changed (it is the default value) as described above.
However, when terminal location information is acquired for the first time after the terminal side processing program is executed, the acquired terminal location information and terminal ID are immediately transmitted to the driver identification device 50 .
Then, after initially transmitting the terminal location information and the terminal ID to the driver identification device 50, the control means 13 displays a comment 19 on the display screen 17 indicating that authentication is in progress and that authentication will automatically end upon completion, as shown in Fig. 7(b). This comment 19 is continuously displayed until an end notification, which will be described later, is received from the driver identification device 50.
Here, the word "authentication" means linking the driver D who carries the mobile terminal 10 with the vehicle V that the driver D is driving, i.e., identifying the vehicle V that the driver D is driving.

Next, the control means 13 judges whether or not a termination notification has been received (step 13). This termination notification is a notification transmitted from the driver identification device 50 when the driver identification device 50 identifies the vehicle V driven by the driver D who possesses the mobile terminal 10, based on the terminal location information and the terminal ID transmitted in step 12.
If the end notification has not arrived (step 13; N), the control means 13 returns to step 12, and acquires the terminal location information again after a seconds have elapsed since the previous transmission, and transmits it together with the terminal ID.
On the other hand, if a termination notification has been received (step 13; Y), the linking by the driver identification device 50 has been completed, so the control means 13 terminates the processing by automatically terminating the app (terminal side processing program) (step 14).
When the app is terminated, the comment 19 displayed on the display screen 17 of the mobile terminal 10 is deleted as shown in FIG. 7(c).

FIG. 8 is a flowchart showing the operation of the driver identification process by the driver identification device 50.
The control means 54 of the driver identification device 50 acquires vehicle position information from the vehicle-mounted device 30 by regular communication (step 51).
That is, the control means 54 continuously receives the vehicle location information and vehicle ID transmitted every b seconds (Figure 5, step 32) from the vehicle-mounted unit 30 of each vehicle V, and stores the received vehicle location information in the vehicle-mounted unit location information storage means 53 for each vehicle ID.

Next, the control means 54 judges whether or not the terminal location information and the terminal ID have been acquired from any one of the terminal devices 10 (step 52).
If not acquired (step 52; N), the control means 54 returns to step 51 and continues acquiring and storing the vehicle position information of the vehicle V.

When the terminal location information and the terminal ID are received from the mobile terminal 10 (step 52; Y), the control means 54 judges whether or not one vehicle V has been detected within the range of Nm (step 53).
That is, the control means 54 determines whether there is only one vehicle within a radius of Nm (100 m in this embodiment) centered on the position of the mobile terminal 10 that received the terminal location information and terminal ID, or whether there are zero or multiple vehicles.
Here, the determination in step 53 by the control means 54 is made for each mobile terminal 10 that has received the terminal location information and terminal ID.

FIG. 9 is an explanatory diagram showing a determination state of driver identification in the driver identification process.
As shown in FIG. 9, the control means 54 judges the number of vehicles V present within a judgment circle S having a radius of Nm and centered on the mobile terminal 10 .
Here, whether or not the vehicle V is present within the judgment circle S is determined from the latest vehicle position information of the on-board unit 30 stored in the on-board unit position information storage means 53, since each vehicle V is equipped with one on-board unit 30, with the position of the vehicle V being the position of the on-board unit 30.

In the state shown in FIG. 9A, two vehicles, a vehicle equipped with an on-board device 30a (hereinafter referred to as vehicle 30a) and a vehicle 30b, are present within a judgment circle S centered on the mobile terminal 10.
On the other hand, in the state shown in FIG. 9B, only the vehicle 30c exists outside the judgment circle S centered on the mobile terminal 10, and no vehicles exist within the judgment circle S.
As described above, the states in Figures 9 (a) and (b) are not the cases where a single vehicle is detected within a range of Nm from the mobile terminal 10 (Figure 8, step 53; N), so the control means 54 does not link the mobile terminal 10 based on the mobile location information of the mobile terminal 10 that made the current judgment (the terminal location information acquired in the immediately preceding step 52), and continues to acquire vehicle location information from each vehicle-mounted unit 30 until it acquires the terminal location information that is next transmitted from the mobile terminal 10 (a seconds later) (step 52; Y).

In this manner, in this embodiment, the judgment circle S is set at intervals of a seconds when new terminal location information is received from the mobile terminal 10, and a determination is made as to whether the driver D and the vehicle V are linked (step 53).
The determination in step 53 (second or later) may be performed before new terminal location information is received from the mobile terminal 10. The process in this case will be described later.

On the other hand, as shown in FIG. 9(c), if in the initial or subsequent judgment (step 53), only one vehicle 30d is present within the judgment circle S (step 53; Y), the driver D of the mobile terminal 10 is linked to the vehicle V equipped with the vehicle-mounted unit 30d (step 54).
That is, returning to FIG. 8, if one vehicle is detected within a range of Nm (within judgment circle S) centered on the mobile terminal 10 (step 53; Y), the control means 54 performs a vehicle linking process (step 54).
That is, the control means 54 identifies the driver D and vehicle V corresponding to the mobile terminal 10 that is the subject of judgment and the detected vehicle-mounted device 30 from the driver information storage means 56 and the vehicle information storage means 55, and links the identified driver D as the driver of the vehicle V and stores it in the linking storage means 57.
This allows the driver D of the vehicle V to be identified.

Next, since the linking (authentication) of the mobile terminal 10 (driver D) to the vehicle-mounted device 30 (vehicle V) is complete, the control means 54 transmits a completion notification to the mobile terminal 10 (step 55) and ends the linking process (driver identification process) for the mobile terminal 10.

The control means 54 continues to receive vehicle location information and vehicle IDs from each vehicle V, and continues to receive terminal location information and terminal IDs from other mobile terminals 10, and performs the linking process.
Here, the control means 54 ends the reception of terminal location information and the like from the mobile terminal 10 by sending an end notification to the mobile terminal 10. On the other hand, when the control means 54 receives vehicle location information and a vehicle ID from each vehicle V, if communication from the vehicle V is interrupted for (m×b seconds) or more, the control means 54 determines that the vehicle V has arrived at the destination and ends the reception. In this case, the last received vehicle location information becomes the arrival point.

FIG. 10 is an explanatory diagram of the ride record.
This ride record is output, for example, to a printer or display screen, by the control means 54 using the result of linking the driver D to the vehicle V.
In the example of the riding record shown in Figure 10, the driving records of the driver XXXX (driver's name) riding in the driving vehicle XXXX (vehicle name, vehicle number, etc.) on the riding date "xx month xx day" are recorded sequentially. The driving record records the departure time and departure point, as well as the arrival time and driving to the arrival point, driven on that day. This driving record is recorded each time the ignition is turned on (departure) and off (arrival) on the riding date.
10 is one example of an output format, and output can be performed in various output formats using information on the driving of the vehicle V by the identified driver D and other information. For example, as other information, the driving speed during the driving and whether or not the driving is efficient based on the calculated fuel consumption may be output.

As described above, according to the driver identification device of this embodiment, the vehicle-mounted unit 30 and the mobile terminal 10 are used to identify the only vehicle-mounted unit 30 that exists within a specified distance centered on the position of the mobile terminal 10, and the driver D who possesses the mobile terminal 10 is identified (linked) as the driver of the vehicle V to which the vehicle-mounted unit 30 is grounded, thereby making it possible to identify the driver of the vehicle with high accuracy.
In particular, it is possible to reduce erroneous recognition compared to when identifying the driver using image recognition or a biometric information acquisition sensor.
Furthermore, compared to the case where a biometric information acquisition sensor is placed to identify the driver, a driver identification system can be constructed by retrofitting an inexpensive on-board unit 30 to the vehicle, making it possible to achieve a low-cost configuration.
Furthermore, since no biometric information is acquired through image recognition or a sensor, the driver can be identified without using any information related to the driver's privacy.

In addition, the driver D only needs to launch the application (terminal side processing program) from the mobile terminal 10 he/she owns before and after starting to drive the vehicle V, which reduces the burden of driving.
Furthermore, since the vehicle-mounted device 30 receives power P from the vehicle V and automatically starts the vehicle-mounted device side processing program, the driver D does not need to perform any processing other than turning on the ignition, which is essential for the vehicle V to run, so there is no load on the vehicle-mounted device 30 from the driver D.

Although the driver identification system using the driver identification device 50 of this embodiment has been described above, the present invention is not limited to the embodiment described above and various modifications are possible.
For example, in the embodiment described above, when more than one vehicle V is detected within the judgment circle S centered on the mobile terminal 10 (step 53; N), the judgment in step 53 is performed with the judgment circle S having the center position for the mobile terminal 10 moved to the position of the mobile terminal 10 received after a seconds. That is, in the embodiment, the judgment circle S is set at an interval of a seconds when new terminal position information is received from the mobile terminal 10, and a determination is made as to whether the driver D is associated with the vehicle V (step 53).

In contrast to this, in this modified example, if the judgment in step 53 is (;N), and the process returns to step 51, the judgment in step 52 may be that the location from the mobile terminal 10 was obtained in the previous judgment (;Y), and the judgment in step 53 may be made accordingly.
In this case, the control means 54 uses the same judgment circle S (same center position) as that used in the previous judgment as the center of the judgment circle S for the mobile terminal 10 until the next terminal location information is received from the mobile terminal 10, and makes the judgment in step 53 based on the newly received (step 51) vehicle location information of the vehicle-mounted unit 30.
Then, after repeating the judgment of step 53 (;N), when the next terminal location information is received from the mobile terminal 10 (a seconds later), the judgment of step 53 is made using a judgment circle S centered on the location of the newly received terminal location information of the mobile terminal 10.
According to the above modified example, the judgment in step 53 can be continuously performed even before the terminal location information of the new mobile terminal 10 is obtained a seconds later, so that the mobile terminal 10 (driver D) and the in-vehicle device 30 (vehicle V) can be linked together, i.e., the driver D driving the vehicle V can be identified more quickly.

In this modified example, further linking may be performed as follows.
That is, as shown in Fig. 9A, when the first association determination (step 53) is performed for the mobile terminal 10, two vehicles 30a and 30b are present inside the determination circle S. In this case, in the subsequent determinations in step 53, only the vehicles 30a and 30b (the vehicle-mounted devices 30a and 30b) that were the targets of the initial determination are the targets of determination. Therefore, in the second and subsequent determinations in step 53, even if a vehicle 30z other than the vehicles 30a and 30b that were the targets of determination is newly present within the determination circle S, the vehicle 30z is excluded from the targets of determination.
Then, when only one of the vehicles 30a, 30b that are the initial judgment targets, for example, the other vehicles 30b (all of them) other than vehicle 30a, moves outside the judgment circle S and only vehicle 30a remains within the judgment circle S, vehicle 30a is made the target to be linked to the driver D of the mobile terminal 10.
