(2) Operation FIGS. 6A and 6B are sequence diagrams showing a distracted driving prevention operation by the distracted driving prevention system 1000.

<At startup>
When the vehicle-mounted device 100 is inserted into the cigar socket in the vehicle and the power supply to the vehicle-mounted device 100 is started from the vehicle CR, the power of the vehicle-mounted device 100 is turned on (step SA1).

The communication unit 130 of the in-vehicle device 100 starts transmitting the beacon signal (step SA2). On the other hand, when the user's mobile terminal 200 receives the beacon signal, it activates the driving prevention application AP (step SA3) and starts connecting to the in-vehicle device 100 using short-range wireless communication (step SA4).

<When driving>
When the control unit 110 of the in-vehicle device 100 detects that the vehicle CR has started running based on each sensor value (specifically, the angular speed sensor 151, the acceleration sensor 152, etc.) obtained from the sensor unit 150 (step). SA5), if there is an application currently in use (for example, a camera application) for the mobile terminal 200 along with the transition to the home screen, a command instructing the inoperability of the application (hereinafter, "home screen transition") Command ”) is transmitted (step SA6). In other words, the control unit 110 of the in-vehicle device 100 sends an instruction to the mobile terminal 200 to limit a part of the functions used by the mobile terminal 200 by using short-range wireless communication.

When the mobile terminal 200 receives the home screen transition command from the in-vehicle device 100, the mobile terminal 200 forcibly displays the home screen Gh (see FIG. 7), and if there is an application currently in use, operates the application. Control is performed so that the application is not accepted (that is, the operation on the application is disabled) (step SA7).

After that, when the mobile terminal 200 receives an incoming call (that is, a call request) from the outside (step SA8), the mobile terminal 200 notifies the in-vehicle device 100 of the call (step SA9). When the control unit 110 of the in-vehicle device 100 receives the incoming call notification via the communication unit 130, it transmits a command (hereinafter, referred to as "incoming call disconnection command") instructing the mobile terminal 200 to reject the incoming call request. (Step SA10). When the mobile terminal 200 receives the incoming call disconnection command from the in-vehicle device 100, it rejects the incoming call request from the outside (step SA11), terminates the call application, and transitions to the home screen Gh (see FIG. 8). In this case, the ringing tone is interrupted and switched to the "two-to-two" sound on the other party's terminal (smartphone or the like) that has transmitted to the user's mobile terminal 200.

<At the end of driving>
After that, when the control unit 110 of the in-vehicle device 100 detects that the vehicle CR has changed from the traveling state to the non-traveling state (step SA12), the mobile terminal 200 is restricted by using short-range wireless communication. An instruction for recovering the used function of the mobile terminal 200 (hereinafter referred to as "used function recovery command") is transmitted (step SA13). When the mobile terminal 200 receives the usage function recovery command, it resumes accepting operations for the application mounted on the mobile terminal 200 (step SA14), and ends the process.

<When sending implementation status information>
FIG. 9 is a sequence diagram showing an operation at the time of transmitting implementation status information.
It is assumed that the user ID for identifying the user and the in-vehicle device ID for identifying the in-vehicle device 100 are registered in the user monitoring database DB 1 of the management server 300 in advance in association with each other.

The mobile terminal 200 acquires the vehicle-mounted device ID when connecting to the vehicle-mounted device 100 (step SB1). The mobile terminal 200 uploads the implementation status information indicating the implementation status of the usage restriction by the driving prevention application AP, including the in-vehicle device ID, to the management server 300 (step SB2). The upload timing can be arbitrarily changed, but may be set, for example, every predetermined time (for example, every 6 hours).

When the management server 300 receives the implementation status information from the mobile terminal 200, the management server 300 identifies the user (user ID) by searching the user monitoring database DB1 using the in-vehicle device ID included in the implementation status information as a search key (step SB3). ).

Then, the management server 300 registers the received implementation status information in the user monitoring database DB1 in association with the specified user (step SB4), and ends the process.

In the above example, only the implementation status information is uploaded from the mobile terminal 200, but for example, the position information acquired by the GPS module 153 of the in-vehicle device 100, the sensor value of the angular velocity sensor 151, the sensor value of the acceleration sensor 152, etc. Information (operation information) representing the operation status of the vehicle CR may be uploaded via the mobile terminal 200.

B. Modifications The present invention is not limited to the above-described embodiment, and can be implemented in various other forms without departing from the gist of the present invention. For this reason, the above embodiments are merely exemplary in all respects and are not to be construed in a limited manner.

<Modification example 1>
In the above-described embodiment, when an incoming call (calling request) is received from the outside to the mobile terminal 200 during traveling, an embodiment in which all the incoming call requests are rejected is illustrated (see steps SA8 to SA11 shown in FIG. 6B). ), Call requests that include a specific phone number may be allowed.

FIG. 10 is a sequence diagram showing an operation when there is a call request according to the first modification.
In the control unit 110 of the in-vehicle device 100, a white list in which telephone numbers (for example, telephone numbers of hospitals and police) for permitting incoming call requests are registered is registered.

When the mobile terminal 200 receives an incoming call request from the outside (step SA8), the mobile terminal 200 notifies the in-vehicle device 100 of the incoming call (step SA9). The incoming call notification includes the telephone number of the caller who made the incoming call request.

When the control unit 110 of the in-vehicle device 100 receives the incoming call notification including the telephone number of the caller via the communication unit 130, the control unit 110 refers to the whitelist, and the telephone number of the caller is registered in the whitelist. It is determined whether the telephone number matches the telephone number (step SA9'). When the control unit 110 of the in-vehicle device 100 determines that the telephone number of the caller does not match any of the telephone numbers registered in the white list (step SA9'; NO), an incoming call is received to the mobile terminal 200. A disconnect command is sent (step SA10).

On the other hand, when the control unit 110 of the in-vehicle device 100 determines that the telephone number of the caller matches any of the telephone numbers registered in the white list (step SA9'; YES), the control unit 110 of the in-vehicle device 100 refers to the mobile terminal 200. , A command instructing the permission of the incoming call request (hereinafter, referred to as "incoming call permission command") is transmitted (step SA10'). When the mobile terminal 200 receives the incoming call permission command from the in-vehicle device 100, the mobile terminal 200 permits an incoming call request from the outside (step SA11') and notifies the user that a call has been received by ringing a ringing tone or the like. Since other operations are the same as those in the present embodiment, the description thereof will be omitted.

<Modification 2>

For example, it is limited when it is detected by the in-vehicle device 100 that the vehicle CR has changed from the running state to the non-running state, and the detection of the non-running state continues for a predetermined time or more (for example, 2 minutes or more). The function of using the mobile terminal 200 may be restored. According to such a configuration, even when the mobile terminal 200 is stopped at a railroad crossing or waiting for a traffic light, the function of using the mobile terminal 200 is limited, and safer driving can be ensured.

In addition, for example, the vehicle-mounted device 100 detects that the vehicle CR has changed from the running state to the non-running state, and the engine (or motor) of the vehicle CR is stopped based on the sensor value acquired by the sensor unit 150. When it is detected and it is detected that the mobile terminal 200 is separated from the mobile terminal 200 by a predetermined distance or more, the restricted usage function of the mobile terminal 200 may be restored. According to this configuration, for example, when the vehicle CR is parked in a parking lot and shopping is carried out at a nearby convenience store or the like, the mobile terminal 200 can be used without any restrictions.
