Terminal device and information provision control method

Technical field

[0001] The present invention relates to a technique for providing position information and estimated arrival time.

Background art

Conventionally, a system for notifying a mobile phone of car navigation position information and estimated arrival time is known. However, such a system required the use of a dedicated mobile phone service. In other words, it was impossible to notify location information and estimated arrival time to a general-purpose telephone without using a special dedicated service.

[0003] Specifically, it is assumed that the user communicates the current location and estimated arrival time when returning home. In this case, the location information of the current location and the estimated arrival time can be easily communicated to the mobile phone that has subscribed to the dedicated service as described above. However, if you join a special dedicated service, you must make a call to your home landline phone after confirming your current location, and not notify the location information and the estimated arrival time directly. It was a great strength. In other words, if you are driving a car, you will need to stop and make a call, which will be a heavy burden on your users! /

[0004] In order to solve the above problems, there has been proposed a system that provides an estimated arrival time based on the current location and destination without using a special dedicated service. ing. (See Patent Document 1).

[0005] In the method of Patent Document 1, the request for providing the current location information and the estimated arrival time is one-way, and the moving user voluntarily notifies the other party of the location information and estimated arrival time that the user wants to notify. There is no description on how to provide. In other words, it does not describe a method for transmitting information to the other party who wants to be notified voluntarily. Further, in Patent Document 1, setting a destination for calculating the estimated arrival time is complicated.

Specifically, in the present embodiment, the input device 60 of the navigation device 1 has setting means for setting a re-notification time. In addition, the communication device of the navigation device 1 38 has an incoming call detecting means for detecting an incoming call from a predetermined telephone and a calling means for making a call to a specific telephone number.

[0033] (Notification method of location information and estimated arrival time)

Next, a method for notifying the location information of the navigation apparatus 1 and the estimated arrival time to a telephone that receives an incoming call without using a special dedicated service will be described.

[0034] In this embodiment, it is assumed that an incoming call is received by the navigation device 1 from a fixed telephone installed at home. In other words, the navigation device 1 shall notify the home landline phone that has received an incoming call the location information of the current location and the information regarding the Z or the estimated arrival time at home.

[0035] Knowing the vehicle position information and estimated arrival time, first, the person calls the navigation device 1 from a predetermined telephone. When a call with the navigation device 1 becomes possible, a specific number indicating that requesting information about the vehicle such as position information and estimated arrival time is pushed.

[0036] When the communication device 38 detects an incoming call and a push of a specific number, the CPU 22 of the navigation device 1 notifies the other party's phone of a prepared voice guidance "searching". Furthermore, based on the detection result of the communication device 38, the CPU 22 specifies the telephone number of the other party who made the call as the notification destination telephone number. In this embodiment, the telephone number corresponding to the fixed telephone at home is specified as the notification destination telephone number. Further, the CPU 22 identifies the location of the notification destination by referring to the telephone number data based on the identified notification destination telephone number!

Here, the telephone number data will be described with reference to FIG. Fig. 2 is a diagram schematically showing the data structure of telephone number data. The phone number data is shown in the phone I

D, phone number and location. The telephone ID is a key for identifying a telephone number and is uniquely given for each telephone number. The location is location information of the landline of the fixed telephone set with the corresponding telephone number, and is specified by an address, latitude / longitude, and the like. The CPU 22 can identify the location of the fixed telephone as the notification destination location by referring to the phone number data so that the conventional phone number can be searched.

[0038] Further, the CPU 22 drives based on the information detected by the GPS receiver 18. Identify the current location of the vehicle. Further, the CPU 22 searches for a route from the current location of the vehicle to the notification destination location. Further, the CPU 22 calculates the estimated arrival time at the notification destination location based on the searched route and the current time. Specifically, the CPU 22 searches the route and calculates the estimated arrival time by referring to the road data stored in the data storage unit 36. Here, the road data is information related to the road network.

[0039] Then, the CPU 22 creates notification data including position information of the current location and information regarding Z or the estimated arrival time at the notification destination location. CPU2 when creating notification data

2 sends the notification data to the other party's destination phone number that is waiting in the voice guidance “Searching”. Here, the notification data is audio data for notifying the location information of the current location and the estimated arrival time at the notification destination location. The CPU 22 creates voice data for performing voice notification using voice guidance prepared in advance. Specifically, based on the voice data, a voice such as “Currently the car is passing OO 巿. It is scheduled to arrive around 0:00” is provided to the landline. The voice guidance is stored in the data storage unit 36 as voice guidance data.

[0040] After sending the notification data to the fixed telephone, the CPU 22 confirms again whether or not there is an incoming call from the notification destination telephone number. When an incoming call is received from the notification destination telephone number again, the CPU 22 determines that the notification partner requests update information. Then, the CPU 22 recalculates the location information of the current location and the estimated arrival time at Z or the notification destination, and retransmits it as notification data to the notification destination telephone number. According to this, the notification partner can easily obtain the latest information on the vehicle by simply calling the navigation device 1 again.

[0041] After transmitting the notification data to the fixed telephone, the CPU 22 determines whether the vehicle has arrived at the notification destination location based on the current location. If the vehicle has not arrived at the notification location, the CPU 22 will arrive at the current location location information and Z or the notification location at preset time intervals, regardless of whether there is an update request from the notification partner. Recalculate the time and re-send it as notification data to the destination phone number.

[0042] Here, a method for setting the re-notification time interval will be described with reference to FIG. Figure 3 shows an example of the re-notification setting screen. The driver can see Figure 3 (a ) Enter the re-notification time interval based on the re-notification setting screen as shown in FIG. In this example, it is assumed that re-notification is performed every 20 minutes as shown in Fig. 3 (b). According to this, it is possible to periodically provide updated data on location information and Z or estimated arrival time. In other words, the latest information can be automatically provided to the other party who wants to know the current location and the estimated arrival time. It is also possible to set the driver not to notify again by turning on the check box corresponding to “unnecessary”.

[0043] (Notification data transmission processing)

Next, the notification data transmission process will be described. FIG. 4 is a flowchart of notification data transmission processing according to this embodiment. The notification data transmission process shown in the figure is periodically performed by the CPU 22 executing a program prepared in advance.

[0044] It is assumed that the re-notification time interval is set to 20 minutes in advance by the vehicle driver as shown in FIG. 3 (b).

[0045] First, a person who has obtained positional information, estimated arrival time,! /, And information on the vehicle, calls the home fixed-phone-power navigation device 1 at home. Furthermore, when a call can be made between the landline telephone and the navigation device 1, a specific number indicating that information on the vehicle is requested is pushed. The CPU 22 of the navigation device 1 first determines whether or not there is an incoming call (step Sl). If there is no incoming call (step Sl; No), the CPU 22 repeats the incoming call judgment at step S1. On the other hand, when there is an incoming call (step Sl; Yes), the CPU 22 determines whether or not the specific number indicating that the information related to the vehicle is requested has been pushed (step S2). If it is pushed! / ヽ (step S2; No), the CPU 22 repeats the processes of steps S1 and S2. On the other hand, when pushed (step S2; Yes), the CPU 22 notifies a voice guidance “searching” to the fixed telephone that is in a call. Further, based on the detection result of the communication device 38, the CPU 22 specifies the telephone number of the other party who made the call as the notification destination telephone number (step S3). Further, the CPU 22 identifies the location of the notification destination by referring to the telephone number data based on the identified notification destination telephone number (step S4). In addition, the CPU 22 identifies the current location of the vehicle and acquires location information of the current location (step S5).

[0046] Then, the CPU 22 determines based on the road data! / The route to is searched (step S6). Further, the CPU 22 calculates the estimated arrival time at the notification destination location (step S7). Further, the CPU 22 creates notification data based on the current location information and the estimated arrival time at Z or the notification destination (step S8). Then, the CPU 22 transmits the notification data to the other party's notification destination telephone number that is kept waiting by the voice guidance “searching” (step S9). Information on the driver's current location and estimated arrival time is provided to the notification partner by landline based on the notification data.

Furthermore, CPU 22 determines whether there is another incoming call from the notification destination telephone number based on the detection result of communication device 38. That is, it is determined whether there is an update request from the notification partner (step S10). If there is an update request (step S10; Yes), the CPU 22 repeats the processing of steps S5 to S10. That is, the CPU 22 recalculates the current position information of the vehicle and the Z or estimated arrival time, and sends the updated information as notification data.

On the other hand, when there is no update request (step S 10; No), the CPU 22 determines whether or not the vehicle has arrived at the notification destination location based on the current location (step SI 1). If it is determined that it has arrived and is! /, NA! / ヽ (step Sl 1; No), the CPU 22 repeats the processing of steps S5 to S11 at a preset interval of 20 minutes. That is, the CPU 22 recalculates the position information of the current location of the vehicle and the Z or estimated arrival time every 20 minutes, and transmits the updated information as notification data. On the other hand, if it is determined that it has arrived (step Sl l; Yes), the CPU 22 completes the notification data transmission process.

[0049] (Modification)

In the above-described embodiment, when there is an incoming call from a person who wants to know information about the vehicle, the notification data is created and transmitted without being disconnected. However, the present invention is not limited to this, and after creating the notification data by cutting once, the navigation device 1 may call the notification destination telephone number and transmit the notification data.

[0050] Notification data transmission processing in such a case will be described in detail. FIG. 5 is a flowchart of notification data transmission processing according to a modification. The notification data transmission process shown in the figure is periodically performed by the CPU 22 executing a program prepared in advance. [0051] It is assumed that the re-notification time interval is set to 20 minutes by the vehicle driver in advance as shown in FIG.

[0052] First, a person who wants to know information about a vehicle such as position information and estimated arrival time calls the navigation apparatus 1 with his fixed telephone power at home. The CPU 22 of the navigation device 1 first determines whether or not there is an incoming call (step S21). If there is no incoming call (step S21; No), the CPU 22 repeats the incoming call judgment at step S21. On the other hand, if there is an incoming call (step S21; Yes), the CPU 22 disconnects the call (step S22). Then, based on the incoming call history detected by the communication device 38, the CPU 22 identifies the telephone number of the other party who made the call as the notification destination telephone number (step S23). Furthermore, the CPU 22 identifies the notification destination location by referring to the telephone number data based on the identified notification destination telephone number (step S24). In addition, the CPU 22 identifies the current location of the vehicle and obtains location information of the current location (step S25).

Then, the CPU 22 searches for a route from the identified current location to the notification destination location based on the road data or the like (step S26). Further, the CPU 22 calculates the estimated arrival time at the notification destination location (step S27). Further, the CPU 22 creates notification data based on the current location information and Z or the estimated arrival time at the notification destination location (step S28). Then, the CPU 22 calls the notification destination telephone number and transmits the created notification data (step S29). When the transmission of the notification data is completed, the CPU 22 disconnects the call with the notification destination telephone number. Information on the driver's current location and estimated arrival time is provided to the notification partner by landline based on the notification data.

[0054] Note that the notification data in the modification may be text data other than the above-described audio data. When the e-mail function is installed in the destination fixed-line telephone, the CPU 22 creates text data for notifying the location information and the estimated arrival time using characters or the like. On the other hand, when the e-mail function is not installed in the destination fixed-line telephone, the CPU 22 creates voice data for voice notification using the voice guidance prepared in advance. As described above, the CPU 22 can automatically select the notification method and provide the location information and the Z or the estimated arrival time by the function installed in the fixed telephone of the notification destination.

[0055] When the notification data is transmitted, the CPU 22 performs notification based on the detection result of the communication device 38. Called phone number Judges whether there is another incoming call. That is, it is determined whether or not there is an update request from the notification partner (step S30). If there is an update request (step S30; Yes), the CPU 22 repeats the processing of steps S25 to S30. That is, the CPU 22 recalculates the current position information of the vehicle and the Z or estimated arrival time, and transmits the updated information as notification data.

On the other hand, when there is no update request (step S30; No), the CPU 22 determines whether or not the vehicle has arrived at the notification destination location based on the current location (step S31). When it is determined that it has arrived! / ヽヽ (step S31; No), the CPU 22 repeats the processing of steps S25 to S31 at a preset interval of 20 minutes. That is, the CPU 22 recalculates the current location information of the vehicle and the Z or estimated arrival time every 20 minutes, and transmits the updated information as notification data. On the other hand, if it is determined that it has arrived (step S31; Yes), the CPU 22 completes the notification data transmission process.

[0057] It should be noted that, in the above-described modification, the power to send notification data to all callee telephone numbers that have received an incoming call is not limited to this, and the present invention is not limited to this. The driver may indicate the person to be notified who provides information about the vehicle.

[0058] In addition, in the above-described modification, when the fixed-line telephone call function is provided, text data is created and the current location information and Z or the estimated arrival time at the notification destination location are transmitted. . At this time, a map 70 as shown in FIG. 6 may be added to the text data. The map 70 indicates the route from the current location 80 to the notification destination location 82, and is created based on the map data stored in the data storage unit 36 in advance.

[0059] As described above, the navigation device 1 according to the embodiment and the modified example is configured such that the vehicle location information and the Z or estimated arrival time for the other party who makes a call without using a special dedicated service. Can be automatically notified by voice data or text data. Further, the navigation device 1 according to the embodiment and the modified example specifies the location from the notification destination telephone number specified based on the incoming call detected by the communication device 38, and determines the estimated arrival time with the location as the destination. Can be calculated. In other words, information about the vehicle By simply calling the navigation device 1, a person who wants to travel can easily provide location information and estimated arrival time without having to perform complicated operations such as setting a separate destination.

[0060] Since the fixed telephone is not limited to the home, the navigation device 1 can be applied to a general-purpose telephone.

[0061] In addition, in the embodiments and the modifications, the explanation is made on the assumption that the car navigation system is used for navigating the vehicle. It is.

Industrial applicability

[0062] The present invention can be used in a navigation apparatus for a moving body represented by a vehicle or the like.
