Description

  The present invention relates to a navigation apparatus having a function of storing a memory point and an application in association with each other.

Conventionally, an application for outputting music, for example, is registered with a memory point, and when the current position of the vehicle approaches or substantially matches the memory point, the application registered with the memory point is executed. (See, for example, Patent Document 1).
JP-A-8-327387

  However, in the above-described patent document 1, since it is necessary to register an application substantially at the same time as registering a memory location, for example, if an attempt is made to register a memory location during driving, Therefore, when it is necessary to operate the operation button many times to register the application, there is a problem that the operation becomes complicated for the user, and the application is registered. There is also a problem that attention is paid to driving, and attention to driving is neglected.

  The present invention has been made in view of the above-described circumstances, and the purpose thereof is to easily register an application for a memory point, thereby improving convenience and ensuring safety. An object of the present invention is to provide a navigation device that can be appropriately secured.

According to the invention described in claim 1, when the voice is input to the voice input means, the control means determines whether or not the input voice matches or partially matches the keyword stored in the storage means. If it is determined that it matches or partially matches, the application associated with the keyword is associated with the predetermined point, and the predetermined point is set as the memory point.
Therefore, the user can register the predetermined point as a memory point by associating the application associated with the keyword with the predetermined point by issuing the keyword, and thus, unlike the conventional one, It is possible to easily register an application for a memory location, to improve convenience, and to ensure safety appropriately.

  According to the invention described in claim 2, when the voice is input to the voice input means, the control means determines whether or not the voice matches or partially matches the keyword stored in the keyword storage means. If it is determined that they match or partially match, the keyword is associated with the predetermined point to make the predetermined point a memory point, and the application selected by the application selection unit is associated with the keyword stored in the keyword storage unit Thus, the selected application is associated with the memory location corresponding to the keyword.

  Therefore, the user can register the predetermined point as a memory point by associating the keyword with the predetermined point by issuing the keyword, and then select the application to associate the application with the keyword, The selected application can be associated with the memory location to which the keyword corresponds, and in this case, the application can be easily registered to the memory location, and the convenience can be improved. Can be secured appropriately.

  Also, in this case, the user can register a memory location by issuing a keyword without inputting a keyword and an application in advance, unlike the one described in claim 1 above. Then, by selecting an application, it is possible to associate the selected application with the memory location corresponding to the keyword. That is, after registering the memory location, an application suitable for the memory location can be selected and registered. .

  According to the invention described in claim 3, when the current position specified by the current position specifying means approaches the memory point stored in the memory point storage means or becomes substantially the same, the control means Since the associated application stored in the application storage means is executed, the user can enjoy the application when the current position approaches or becomes substantially the same as the memory location.

  According to the invention described in claim 4, the control means satisfies the execution condition of the application at a place other than the stored memory spot, and the voice input to the voice input means is the stored keyword. When it is determined that they match or partially match, the application corresponding to the keyword is executed as a function different from the memory function of the memory point, so that the user is when the current position approaches the memory point or substantially the same. Even when it is not, the application can be enjoyed by issuing a keyword.

  According to the invention described in claim 5, since the control means is configured to be able to store a plurality of memory points for one keyword, the user can issue the same keyword at a plurality of points, The same application can be registered for multiple memory points, and multiple memory points can be categorized for one application.

Note that the information recording medium is not limited to the DVD-ROM, and for example, a CD-ROM, a memory card, or the like may be used.

  The operation switch group 5 includes a mechanical switch disposed around the display device 11 and a touch switch formed on, for example, a color liquid crystal display of the display device 11. Used to register keywords and applications.

  The vehicle data input / output device 6 outputs vehicle state data representing the state of the vehicle input from the ECU, for example, to the control circuit 2. The mobile phone connection device 7 is configured to connect a mobile phone (not shown). The VICS receiver 8 receives VICS information from the outside. The voice input device 9 inputs the voice uttered by the user, and the voice output device 10 outputs, for example, voice necessary for route guidance from the current position to the destination. The display device 11 is composed of, for example, a color liquid crystal display, displays a road map, displays a pointer indicating the current position of the vehicle and the traveling direction in superposition with the display, and also displays a target from the current position. When the route guidance to the ground is executed, the guidance route to be traveled is displayed so as to overlap the road map. The display device 11 is not limited to a color liquid crystal display, and may be composed of an organic EL or a plasma display.

  The external memory 12 is configured by a flash memory card or the like, and stores, for example, guidance route data from the current position to the destination obtained by route calculation processing by the control circuit 2, and in this embodiment, a keyword, It also stores applications and memory points. The function of the external memory 12 can also be realized by a storage element (such as a RAM) in the control circuit 2. In this case, the external memory 12 may be provided as necessary. The keyword, application, and memory point may be stored in separate storage memories (storage means).

  The voice recognition unit 13 analyzes the voice input to the voice input device 9 based on a predetermined voice recognition algorithm. The remote control sensor 14 receives an operation signal from the operation remote controller 15 by radio waves and outputs it to the control circuit 2.

  The audio device 20 receives, for example, an AM radio wave or FM radio wave and outputs a radio broadcast, a cassette function that reproduces music data recorded on a cassette tape and outputs music, and is recorded on a music CD. Various functions such as a CD function for reproducing music data and outputting music are installed, and operate based on a control instruction input from the control circuit 2. In this case, an output device for outputting radio broadcasts and music may be provided exclusively for the audio device 20 or may be configured to be shared by the audio output device 10 described above.

Next, the operation of the above configuration will be described with reference to FIGS. here,
(1) Processing for registering an application for a memory location (2) Each processing for executing an application stored in association with a memory location when the current position approaches the memory location will be described in sequence.

(1) Processing for Registering Application for Memory Point First, “processing for registering an application for a memory point” will be described with reference to the flowchart shown in FIG.

  When the control circuit 2 detects that the user has performed an operation related to registration of the keyword and the application, for example, with the operation remote controller 15 (“YES” in step S1), the control circuit 2 waits for the keyword to be input (step S2). When it is detected that a keyword has been input (“YES” in step S2), the input keyword is stored in the external memory 12 (step S3). In this case, as a method for inputting a keyword, for example, there are a method by voice input, a method by key input, and the like. The user issues a keyword or operates a key of a 50-sound table displayed on the display device 11. By doing so, it becomes possible to input a keyword.

  Next, the control circuit 2 waits for an application to be input (step S4). When the control circuit 2 detects that an application has been input ("YES" in step S4), the input application is stored in the external memory 12. Store (step S5). In this case, as a method for inputting the application, for example, there is a method by key input, and the user inputs the application by operating a key on the operation remote controller 15 or a key displayed on the display device 11. It becomes possible. Then, the control circuit 2 associates the keyword with the application (Step S6).

  As a result, the user utters, for example, “p”, “b”, “po”, “-”, “z” in response to the transition of the display screen as shown in FIG. By operating the “3” button and the “5” button, the keyword “Propose” and the application “output the third music of the third CD of the CD changer in the audio device 20” are registered in association with each other. Can do. In this case, the keyword is input first, and the application is not input later, but the application may be input first and the keyword may be input later.

  Next, when the control circuit 2 determines that, for example, a setting related to execution of the memory location registration mode by the user has been made (“YES” in step S7), the keyword and the application are associated with the external memory 12 at that time. It is determined whether it is stored (step S8). When the control circuit 2 detects that the keyword and the application are stored in association with each other in the external memory 12 (“YES” in step S8), the voice is input to the voice input device 9. It waits for that (step S9).

  Next, when the control circuit 2 detects that voice is input to the voice input device 9 (“YES” in step S9), the voice recognition unit 13 recognizes the input voice (step S10). Then, it is determined whether or not the input voice matches the keyword stored in the external memory 12 (step S11). In this case, the control circuit 2 may determine that the two voices match when all the sounds of the voice match the keyword, or both match when a part of the voice matches the keyword (partial match). You may determine that.

  When the control circuit 2 detects that they match (“YES” in step S11), the control circuit 2 detects the current position (predetermined point) detected based on the detection signal input from the position detector 3 at that time. ) Is stored in the external memory 12 as a memory location (step S12), and the application associated with the keyword and stored in the external memory 12 is associated with the memory location (step S13). The memory point to be stored may be near the detected current position.

  As a result, for example, when the user issues the keywords “p”, “b”, “po”, “-”, “z” during driving, the point that issued the keyword “proposal” is used as the memory point. In addition, an application “output the third music of the third song of the CD changer in the audio device 20” can be registered in association with the memory point.

(2) When the current location approaches the memory location, the process of executing the application stored in association with the memory location. Next, “When the current location approaches the memory location, it is associated with the memory location. The process of executing the stored application will be described with reference to the flowchart shown in FIG.

  The control circuit 2 monitors whether or not the current position has been updated when the vehicle is running (step S21), and when it detects that the current position has been updated (“YES” in step S21), at that time It is then determined whether or not the memory location is stored in the external memory 12 (step S22). When the control circuit 2 detects that the memory point is stored in the external memory 12 at that time (“YES” in step S22), for example, it calculates the distance between the current position and the memory point. By comparing with the threshold value, it is determined whether or not the current position has approached the memory point (step S23).

  Next, when the control circuit 23 detects that the current position has approached the memory point because, for example, the distance between the current position and the memory point is less than the threshold ("YES" in step S23), the memory It is determined whether or not the sound associated with the point is stored in the external memory 12 (step S24), and when it is detected that the sound associated with the point in memory is stored in the external memory 12 (in step S24) “YES”), the sound is output from the sound output device 10 (step S25), and it is determined whether or not the image associated with the memory location is stored in the external memory 12 (step S26), and is associated with the memory location. When it is detected that the received image is stored in the external memory 12 (“YES” in step S26), the image is displayed on the display device 11. That (step S27).

Then, the control circuit 2 determines whether or not the application associated with the memory location is stored in the external memory 12 (step S28), and indicates that the application associated with the memory location is stored in the external memory 12. Is detected ("YES" in step S28), the application is executed (step S29).
As a result, the user registers the application “output the music of the third song of the third CD changer in the audio device 20” in association with the memory location, for example, as described above, so that the current position of the vehicle When is approaching the memory point, he can listen to the third music of the third CD changer.

  As described above, according to the first embodiment, when a keyword is issued in the vehicle navigation device 1, the application associated with the keyword is associated with the predetermined point, and the predetermined point is defined as the memory point. The user can register the predetermined point as the memory point by associating the application associated with the keyword with the predetermined point by issuing the keyword, and thereby the memory point. Application can be easily registered, convenience can be improved, and safety can be ensured appropriately.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. In addition, description is abbreviate | omitted about the same part as above-mentioned 1st Embodiment, and a different part is demonstrated. The first embodiment described above describes a case where an application is registered in association with a memory point by first storing a keyword and an application in association with each other and then storing a memory point. On the other hand, in the second embodiment, only the keyword is stored first, then the memory point is stored, and then the application is stored, so that the application is associated with the memory point. It explains the case of being registered. In the second embodiment, the external memory 12 corresponds to the keyword storage means in the present invention.

  When the control circuit 2 detects that the user has performed an operation related to keyword registration with, for example, the operation remote controller 15 (“YES” in step S31), the control circuit 2 waits for the keyword to be input (step S32). When it is detected that a keyword has been input (“YES” in step S32), the input keyword is stored in the external memory 12 (step S33). Also in this case, as a method for inputting a keyword, for example, there are a method by voice input and a method by key input, and the user issues a keyword or operates a key of a 50-sound table displayed on the display device 11. It becomes possible to input keywords.

As a result, the user can register the keyword “Propose” by, for example, uttering the sounds “B”, “B”, “P”, “-”, and “Z”.
Next, when the control circuit 2 determines that the setting related to the execution of the memory location registration mode by the user is made (“YES” in step S34), for example, whether or not the keyword is stored in the external memory 12 at that time. Is determined (step S35). When the control circuit 2 detects that the keyword is stored in the external memory 12 at that time (“YES” in step S35), it waits for the voice to be input to the voice input device 9 (step S35). S36).

  Next, when the control circuit 2 detects that a voice is input to the voice input device 9 (“YES” in step S36), the voice recognition unit 13 recognizes the input voice (step S37). Then, it is determined whether or not the input voice matches the keyword stored in the external memory 12 (step S38). When the control circuit 2 detects that they match (“YES” in step S38), the control circuit 2 determines the current position detected based on the detection signal input from the position detector 3 at that time as the memory location. Is stored in the external memory 12 (step S39).

  Next, when the control circuit 2 detects that the user has performed an operation related to registration of the application, for example, with the operation remote controller 15 (“YES” in step S40), it waits for the application to be input (step S41). When it is detected that an application has been input (“YES” in step S41), the input application is stored in the external memory 12 in association with the keyword (step S42). Also in this case, as a method of inputting the application, for example, there is a method by key input, and the user inputs the application by operating a key of the operation remote controller 15 or a key displayed on the display device 11. It becomes possible to do. Then, the control circuit 2 associates the application associated with the keyword and stored in the external memory 12 with the memory point (step S43).

  As a result, for example, when the user operates the “3” button and the “5” button of the operation remote controller 15, an application “output music of the third song of the third CD changer in the audio device 20” is stored in the memory. It is possible to register in association with a point.

  As described above, according to the second embodiment, when a keyword is issued in the vehicle navigation device 1, the keyword is associated with a predetermined point, the predetermined point is stored as a memory point, and the application is Since the selected application is associated with the memory point corresponding to the keyword by associating with the keyword, the user associates the keyword with the predetermined point by issuing the keyword, and the predetermined point Can then be registered as a memory location, and then by selecting an application, the application can be associated with a keyword, and the selected application can be associated with the memory location to which the keyword corresponds. Memo It is possible to easily perform the registration of the application with respect to the point, it is possible to improve convenience, moreover, it is possible to appropriately ensure the safety.

  Also, in this case, unlike the one described in the first embodiment, the user registers a memory location by issuing a keyword without inputting a keyword and an application in advance. Then, by selecting an application, the selected application can be associated with the memory location to which the keyword corresponds. That is, after registering the memory location, the application appropriate for the memory location can be selected and registered. Can do.

(Other embodiments)
The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.

The configuration is not limited to the configuration applied to the vehicle navigation device, and may be a configuration applied to a portable navigation device portable by a person.
Not only the configuration that executes the application when the current position of the vehicle approaches the memory point, but also the configuration that executes the application when the current position of the vehicle substantially matches the memory point (when the vehicle substantially passes the memory point). There may be.

  Even when the current position of the vehicle is not approaching the memory point, the application stored in association with the keyword may be executed when the keyword is issued. In that case, for example, when a keyword is issued after the word “registration” is issued, the keyword is registered. On the other hand, for example, when a keyword is issued after the word “execution” is issued, the keyword is issued. If the application stored in association with is configured to be executed, they can be distinguished. Moreover, the structure which distinguishes them based on whether a specific switch (for example, PTT switch) was operated may be sufficient.

  The configuration may be such that a plurality of memory points can be stored for one keyword, and if configured in this way, the user can issue the same keyword to a plurality of points by issuing the same keyword at a plurality of points. It is possible to register for a point and categorize multiple memory points for one application.

  The configuration may be such that a plurality of applications and a plurality of memory points can be associated with each other and stored at the same time. With such a configuration, for example, the first music is played when the vehicle approaches the first memory point. This can be automatically output, and subsequently, the second music can be automatically output when the vehicle approaches the second memory point.

  The application is not limited to the one that outputs music, for example, one that reproduces and outputs a pre-recorded voice, one that sounds a horn, or one that drives a vehicle component (such as a wiper) good.
