[0012] (Functional configuration of data processing apparatus)

First, the functional configuration of the data processing apparatus that is relevant to the embodiment of the present invention will be described. FIG. 1 is a block diagram showing a functional configuration of a data processing apparatus according to an embodiment of the present invention. A data processing apparatus 100 that is effective in the embodiment is a portable computer terminal that can move together with a mobile object.

Here, the moving body is a movable object, such as a vehicle, a ship, or a human. For example, when the moving body is a vehicle, the data processing apparatus 100 is realized by a navigation device mounted on the vehicle, and when the moving body is a human, the data processing apparatus 100 is performed by a mobile phone owned by the person. Realized.

In FIG. 1, a data processing device 100 includes a storage device 101, an update unit 102, a detection unit 103, a route information acquisition unit 104, a traffic information acquisition unit 105, and a history storage unit 106. Unit 107, output unit 108, input unit 109, and restart unit 110.

The storage device 101 stores various data for the data processing device 100 to execute predetermined processing. Specifically, the storage device 101 stores, for example, map data and function data. Specifically, the predetermined process is, for example, a process of displaying a map based on the map data stored in the storage device 101 on the display screen.

The update unit 102 updates the data stored in the storage device 101 using the update data. Here, the update data specifically refers to, for example, when the data stored in the storage device 101 is map data, it relates to a newly constructed road or facility with respect to the map data. Map data with added data. The update data may be recorded on, for example, a portable recording medium, or may be recorded on an external device that can communicate with the data processing device 100. When updating, the update unit 102 deletes the data stored in the storage device 101 and then stores the update data recorded in the recording medium or the external device in the storage device 101. [0017] The detection unit 103 detects the state of the moving body. Specifically, the detection unit 103 detects, for example, the current location of the moving body as the state of the moving body. The current location of the mobile object can be detected, for example, by receiving a GPS signal from a GPS satellite. For example, when the moving body is a vehicle, the current position of the moving body is determined according to the output value of the acceleration sensor or the vehicle speed sensor that detects the behavior of the vehicle in addition to the GPS signal received by the GPS satellite force. You may make it detect.

[0018] In addition, for example, the detection unit 103 may detect the moving speed of the moving body as the state of the moving body. Specifically, when the moving body is a vehicle, for example, the moving speed of the moving body may be detected according to the output value from the acceleration sensor described above.

The route information acquisition unit 104 acquires information on a route to a predetermined point. Here, the predetermined point is, for example, a point designated by the user of the data processing apparatus 100 as a destination point intended for arrival. The route is, for example, an optimum route that connects the current point detected by the detection unit 103 and a predetermined point.

[0020] The traffic information acquisition unit 105 acquires road traffic information. Here, the road traffic information is, for example, information such as traffic restriction sections on general roads and expressways, presence / absence of traffic jams, length of traffic jams, and causes of traffic jams. The road traffic information can be obtained using, for example, VICS (Vehicle Information and Communication System). VICS is a registered trademark.

[0021] The history storage unit 106 stores the movement history of the moving object. Here, the movement history is a point where the moving body has reached or passed in the past, a travel path, a route through the destination point, and the like.

[0022] When the data is updated by the update unit 102, the calculation unit 107 performs a restartable timing for validating the updated data in the storage device 101 based on the state of the mobile object. calculate. Here, the calculation unit 107 may calculate a timing at which the user is less likely to use the data processing device 100 as a timing at which restart is possible.

[0023] In addition, when the detection unit 103 described above detects the current location of the moving object, the calculation unit 107 can restart the data processing apparatus 100 based on the current location. May be calculated. Specifically, the calculation unit 107 calculates the timing at which the moving body moves within a predetermined range including the registration point stored in the storage device 101 as a timing that can be restarted. Here, the registration point is a point where the user of the data processing apparatus 100 performs a registration operation, for example, “home” or “workplace”.

[0024] Conversely, the calculation unit 107 may calculate the timing at which the moving body is entering the intersection or the timing of moving in the vicinity of the interchange on the expressway as a timing at which restart is impossible.

[0025] In addition, the calculation unit 107 uses the route acquired by the route information acquisition unit 104 described above to calculate a timing at which restart is possible based on the current location of the mobile object and a route to a predetermined location. May be. Specifically, the calculation unit 107 calculates, for example, the timing at which the moving body moves along the route for a while on the route as the timing at which restarting is possible.

[0026] In addition, the calculation unit 107 may calculate a timing at which restart is possible based on the road traffic information acquired by the traffic information acquisition unit 105 described above. Specifically, for example, when there is a traffic jam around the current location of the mobile object or in front of the mobile object, that is, when the mobile object is likely to be jammed, the calculation unit 107 determines that the mobile object is The timing that is expected to fall in a traffic jam is calculated as the timing that can be restarted.

[0027] In addition, the calculation unit 107 predicts that the moving body will be jammed on the route acquired by the route information acquisition unit 104 when the traffic jam exists within a predetermined distance from the current location of the moving body. The timing is calculated as a timing at which restart is possible.

In addition, the calculation unit 107 may calculate a timing at which the data processing apparatus 100 can be restarted based on the movement history stored in the history storage unit 106. Specifically, for example, the calculation unit 107 calculates the timing at which the moving body moves around a point that has reached or passed many times in the past as the timing at which the data processing apparatus 100 can be restarted. .

[0029] Further, the calculation unit 107 includes a current location detected by the detection unit 103, a route acquired by the route information acquisition unit 104, road traffic information acquired by the traffic information acquisition unit 105, and a history storage unit 106. All or part of the movement history stored by The timing at which the data processor 100 can be restarted may be calculated by combining the information.

The output unit 108 outputs information related to the timing calculated by the calculation unit 107. The output unit 108, for example, “Updated map data. Restart the device. And the like are output using voice as information about timing. The output unit 108 may output the same message using characters or images via the display screen, or may output the same message using voice and characters or images.

[0031] The input unit 109 accepts an input by the user as to whether or not to restart in response to the output of information related to the timing described above. For example, information related to the timing output by the output unit 108 described above is output, and an operation key for intentionally indicating whether or not to restart is input-acceptable. Accepts user input for restarting or not.

The restart unit 110 restarts the data processing apparatus 100 at the timing calculated by the calculation unit 107. When restarting, the restart unit 110 first turns off the power of the data processing device 100. At this time, if there is a function in the middle of processing in the data processing apparatus 100, the power data processing apparatus 100 is turned off by performing predetermined termination or interruption processing for each function.

Next, the data processing apparatus 100 is activated. At this time, if there is data updated by the update unit 102, the data processing apparatus 100 is activated with the updated data enabled so that the updated data can be used.

[0034] (Data update processing procedure of data processing device)

Next, the data update processing procedure of the data processing apparatus 100 will be described. FIG. 2 is a flowchart showing a data update processing procedure of the data processing apparatus 100. In the flowchart of FIG. 2, first, the data stored in the storage device 101 is waited until it is updated by the updating unit 102 (step S 201: No), and when it is updated (step S201: Y es ) Calculates a restartable timing for validating the data updated by the calculation unit 107 (step S202).

In step S202, based on the state of the moving object detected by detection unit 103. Thus, the timing of restart may be calculated, and when the route information acquisition unit 104 acquires the information of the route to the predetermined point, the current point of the moving object and the predetermined point Based on the route, the timing at which restart is possible may be calculated.

[0036] In step S202, when road traffic information is acquired by the traffic information acquisition unit 105, the timing at which the vehicle can be restarted is calculated based on the current location of the mobile object and the road traffic information. May be. Furthermore, in step S202, the timing at which restarting may be performed may be calculated based on the current location of the moving object and the movement history stored in the history storage unit 106.

[0037] Then, information related to the timing calculated in step S202 is output by the output unit 108 (step S203), and it is determined whether or not to restart the data processing apparatus 100 at a timing at which the restart is possible. (Step S204). In step S204, for example, the input unit 109 accepts an input indicating that the user will also perform a restart. Depending on whether an input indicating that the restart is not performed is received, the data processing is performed at a timing that can be restarted. It is determined whether or not the device 100 is to be restarted.

[0038] In step S204, when the data processing apparatus 100 is restarted at the restartable timing output in step S203 (step S204: Yes), the restart unit 110 can be restarted. The data processor 100 is restarted at the timing (step S205), and the series of processes is terminated. If the data processing apparatus 100 is not restarted (step S204: No), the series of processing ends.

[0039] As described above, according to the data processing device 100 of the embodiment, when the data stored in the storage device 101 is updated by the update unit 102, the data is detected by the detection unit 103. Based on the state of the moving body, the restarting unit 110 can perform the restart at the timing calculated by the calculating unit 107.

[0040] Therefore, the data processing apparatus 100 can be restarted at an appropriate timing, whereby the user can validate and use the updated data at an earlier stage.

[0041] Further, according to the data processing device 100 of the embodiment, in response to the output of the information related to the timing by the output unit 108, an input as to whether or not to restart by the user When received by the unit 109, the restart unit 110 can restart at the timing calculated by the calculation unit 107.

Accordingly, the data processing apparatus 100 can be restarted at an appropriate timing reflecting the user's intention to approve the restart.

In addition, according to the data processing device 100 of the embodiment, based on the current location of the moving object detected by the detection unit 103, the timing at which the restart can be calculated by the calculation unit 107 is calculated and calculated. At the timing, the restart unit 110 can restart.

Therefore, the data processing apparatus 100 can be restarted at an appropriate timing according to the current location where the mobile object is located.

Furthermore, according to the data processing apparatus 100 of the embodiment, based on the current location of the moving object detected by the detection unit 103 and the route to the predetermined point acquired by the route information acquisition unit 104. The timing at which the restart can be performed is calculated by the calculation unit 107, and the restart by the restart unit 110 can be performed at the calculated timing.

Therefore, the data processing apparatus 100 can be restarted at an appropriate timing on the route to the predetermined point.

In addition, according to the data processing device 100 of the embodiment, based on the current location of the moving object detected by the detection unit 103 and the road traffic information acquired by the traffic information acquisition unit 105, the calculation unit The timing at which restart is possible is calculated by 107, and the restart unit 110 can restart at the calculated timing.

[0048] Therefore, the data processing apparatus 100 can be restarted at an appropriate timing in consideration of traffic conditions around the current location of the mobile object.

Further, according to the data processing apparatus 100 of the embodiment, the calculation unit 107 is based on the current location of the moving object detected by the detection unit 103 and the movement history stored by the history storage unit 106. The timing at which restart is possible is calculated by, and the restart unit 110 can restart at the calculated timing.

[0050] Therefore, the data processing apparatus 100 can be restarted at an appropriate timing based on the history of the moving object. Example

Then, when various data recorded on the magnetic disk 305 are updated, the update data is read by the optical disk drive 306 and used for various data update processing.

The audio IZF 308 is connected to a microphone 309 for audio input and a speaker 310 for audio output. The voice received by the microphone 309 is AZD converted in the voice IZF308. For example, the microphone 309 may be installed near the sun visor of the vehicle, and the number may be one or more. From the speaker 310, a sound obtained by DZA-converting a predetermined sound signal in the sound IZF 308 is output. Note that sound input from the microphone 309 can be recorded on the magnetic disk 305 or the optical disk 307 as sound data.

[0066] Examples of the input device 311 include a remote controller having a plurality of keys for inputting characters, numerical values, and various instructions, a keyboard, and a touch panel. The input device 311 may be realized by any one form of a remote control, a keyboard, and a touch panel. The input device 311 may be realized by a plurality of forms.

This is realized by the CPU 301 executing a predetermined program and controlling each part in the navigation device 300.

[0076] (Data update processing procedure of navigation device)

Next, a data update processing procedure of the navigation device 300 will be described. FIG. 4 is a flowchart showing a data update processing procedure of the navigation device 300. The data update processing procedure shown in FIG. 4 is executed when the update data is recorded in the optical disk drive 306, the optical disk 307 is inserted, and the state is changed.

[0077] In the flowchart of FIG. 4, first, it waits until data update is started (step S401: No), and when the update is started (step S401: Yes), it is recorded on the optical disc 307. The data file for the update data is copied to the magnetic disk 305 by the magnetic disk drive 304 (step S402).

[0078] In step S402, the compressed data file recorded on the optical disc 307 is temporarily recorded in the RAM 303 or the like in a decompressed state, and a data file related to the decompressed data file is stored. Erase from magnetic disk 305. Thereafter, the data file temporarily recorded on the RAM 303 or the like is recorded on the magnetic disk 305. Such processing is sequentially performed for each data file.

[0079] Then, the process waits until it is determined that there is a data file that has been copied from the optical disk 307 to the magnetic disk 305 by copying in step S402 (step S403: No), and there is a data file that has been copied. In the case (step S403: Yes), the timing for restarting the navigation device 300 is calculated (step S404).

Here, in step S404, specifically, based on the current position of the vehicle detected by CPU 301, the timing at which the vehicle moves within a predetermined range including the point recorded by magnetic disk 305 is set. This is calculated as the timing at which the navigation device 300 is restarted.

[0081] Further, in step S404, the copy completed in step S403: Yes. If the route is being guided when it is determined that there is a single file, the timing at which the vehicle travels on the route and moves for a while without turning right or left is calculated as the timing at which the navigation device 300 is restarted. Furthermore, the timing when the vehicle is approaching the intersection and the timing when the vehicle moves in the vicinity of the interchange on the expressway may be calculated as a timing at which restart is not possible.

[0082] Further, in step S404, the navigation apparatus 300 is restarted at a timing when the vehicle is predicted to be stuck in a traffic jam area in consideration of the road traffic information acquired via the communication IZF 314. Calculate as timing.

[0083] In step S404, the current position of the navigation device 300 and the operation history of the navigation device 300 are used to determine whether or not the vehicle has reached or passed many times in the past. The timing when the navigation device 300 can be restarted is the timing when the navigation device 300 is restarted, that is, when the vehicle user moves near the point where the user of the vehicle does not have to look at the map display of the navigation device 300, etc. calculate.

Next, it is determined whether the notification timing has arrived (step S405). If it is not the notification timing (step S405: No), the process returns to step S402. If it is the notification timing (step S405: Yes), “Map data has been updated. Restart the device. Is output from the speaker 310, and a pop-up with the same content is displayed on the display 313 to notify that it is time to restart (step S406).

Force not shown In step S 406, a pop-up for confirming the user's intention as to whether or not to restart is also displayed on display 313. Specifically, for example, a pop-up including keys such as “Restart now” and “Restart later” is displayed on the display 313. The two keys in the popup can accept either selection.

[0086] Then, it is determined whether or not to restart (step S407). In step S407, the user operates the input device 311 to determine whether one of the two keys in the pop-up has been operated. Specifically, when the “Restart Now” key is selected, it is determined to restart, and the “Restart Later” key is selected. When is selected, it is determined that the system will not restart.

In step S407, when restarting (step S407: Yes), restart is performed (step S408). If not restarted (step S407: No), the process proceeds to step S409. In step S408, at the time of restart, restart is performed in a state where the updated data can be used until it is determined in step S407: Yes that restart is performed.

[0088] Thereafter, it is determined whether or not copying of all data files recorded on the optical disc 307 has been completed (step S409). If not completed (step S409: No), the process proceeds to step S402. If the process returns and is finished (step S409: Yes), the series of processes is finished.

[0089] As described above, according to the navigation device 300 of the embodiment, it is possible to restart at an appropriate timing, which enables the user to make the updated data effective at an earlier stage. Can be used.

[0090] Furthermore, according to the navigation device 300 of the embodiment, it is possible to restart at an appropriate timing reflecting the user's intention.

Furthermore, according to the navigation device 300 of the embodiment, it can be restarted at an appropriate timing according to the current location where the vehicle equipped with the navigation device 300 is located.

[0092] Further, according to the navigation device 300 of the embodiment, the necessity of using the navigation device 300 by a user such as when the vehicle is moving along a route on a route to a predetermined point. Can be restarted at a low timing.

Further, according to the navigation device 300 of the embodiment, the vehicle can be restarted at a timing when the vehicle is jammed and it is less necessary for the user to use the navigation device 300.

[0094] Further, according to the navigation device 300 of the embodiment, there is no need for a user to use the navigation device 300, such as when the vehicle repeatedly travels or passes through or near a point where the vehicle has repeatedly reached or passed. It can be restarted at a low timing.

Note that the data update method described in the present embodiment is performed by executing a prepared program on a computer such as a personal computer or a workstation. Can be realized. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
