  In the car navigation apparatus disclosed in Patent Document 1 and the in-vehicle device described in Patent Document 2, in particular, a transmission format for transmitting character string data such as an electronic mail to a driver driving the vehicle. Can be selected appropriately. However, even if the transmission format of character string data such as e-mail is appropriate, the car navigation device disclosed in Patent Document 1 can transmit information on the contents and amount unnecessary for the driving driver. There is sex. On the other hand, in the in-vehicle device or the like shown in Patent Document 2 described above, a part of character data such as an e-mail is simply deleted according to the mail output length. There is a possibility that the contents of the character string data such as the transmitted electronic mail cannot be easily understood.

  The present invention has been made to address the above-described problems, and one of its purposes is an information providing device that provides information including character string data of appropriate contents and amount to a vehicle occupant, To provide an information providing method and an information providing system.

  In order to achieve the above object, an information providing apparatus according to the present invention includes control means for controlling a providing mode when various information is provided to a vehicle occupant.

  The information providing apparatus according to the present invention is characterized in that the control unit obtains information including at least character string data from the outside, and determines a complexity representing the grammatical complexity of the obtained information in the character string data. Converting the character string data so as to simplify the grammatical complexity of the character string data according to the determined complexity, and providing post-conversion information including the converted character string data It is in. Note that in this case, the control means is an information acquisition means for acquiring information including at least character string data from the outside, and a complexity representing the grammatical complexity in the character string data of the information acquired by the information acquisition means. A character string for converting the character string data so as to simplify the grammatical complexity of the character string data according to the complexity determined by the complexity determining means; It is also possible to provide data conversion means and information providing means for providing information after conversion including the converted character string data.

  According to another aspect of the present invention, there is provided an information providing method for providing a variety of information by controlling a provision mode when various information is provided to a vehicle occupant, the information including at least character string data from the outside. And determining the complexity representing the grammatical complexity in the character string data of the acquired information, and the grammatical complexity in the character string data is simplified according to the determined complexity The character string data may be converted as described above, and converted information including the converted character string data may be provided.

  Furthermore, another feature of the present invention includes a terminal device that can be mounted on a vehicle, and a providing center that provides various information to the terminal device, and the providing center provides the various information to the vehicle via the terminal device. An information providing system for controlling and providing a provision mode when providing to an occupant of the vehicle, wherein the providing center acquires information including at least character string data from the outside, and the acquired information in the character string data The complexity representing the grammatical complexity is determined, and the character string data is converted according to the determined complexity so that the grammatical complexity of the character string data is simple, and the converted character The converted information including column data is provided to the terminal device, the terminal device acquires the converted information including the converted character string data provided from the providing center, and the vehicle It is also possible to inform the information of the converted including the character string data described above transformation the acquired membered.

  According to these, for example, when information including character string data is transmitted to the driver of the vehicle from the outside, the complexity representing the grammatical complexity in the character string data of this information is determined, and the determined complexity Depending on the degree, the transmitted character string data can be converted so as to simplify the grammatical complexity of the character string data. And the information after the conversion including the character string data converted so as to be simplified (simplified) can be provided to the driver of the vehicle. Accordingly, since a part of the character string data included in the information is not simply deleted, the amount of information provided by the converted information is not deficient. Further, since the grammatical complexity can be eliminated, the contents of information including the simplified (simplified) character string data can be easily understood. Thereby, for example, when the converted information is provided to the driver who is driving, the content of the information provided by the driver can be understood very well.

  Specifically, in this case, the control means includes the complexity of the acquired information in the character string data in the number of sentences represented by the character string data, the length of the sentence, and the sentence. It can be determined based on at least one of the number of double negations, the number of conjunctions connecting the sentences, and the number of modifiers included in the sentences. In this case, the control means converts the double negation included in the sentence to affirmation, deletes the modifier included in the sentence, and includes a specific noun in the sentence. The character string data can be converted so that the grammatical complexity of the character string data is simplified by at least one of deleting missing sentences. Further, in this case, the control means uses position information indicating the position of the vehicle on which the occupant rides and position information indicating the position of the third party who transmitted the information acquired from the outside, and The character string data can be converted so that the grammatical complexity of the character string data is simplified according to the positional relationship with the position of the third party.

  According to these, grammatical complexity can be determined based on, for example, the number and length of sentences, the number of double negations, the number of conjunctions, the number of modifiers, and the like. Then, in order for the driver of the vehicle to whom the information is provided, in particular, the driver can easily and quickly understand the contents, the double negative affirmation or the qualifier is deleted, or a specific noun (for example, the passenger Character string data can be converted, for example, by deleting sentences that do not contain the nouns (keywords) that are of interest, and the grammatical complexity of the character string data included in the information can be eliminated. Therefore, for example, useful content and information on the amount can be appropriately provided to the driver during driving.

  Another feature of the information providing apparatus according to the present invention is that the control means obtains driving state information representing a driving state of the vehicle from a vehicle on which the occupant gets, and based on the acquired driving state information, It is determined whether the vehicle is in any one of a parked state, a parked state, and a driving state, and the converted character string data including the converted character string data is determined according to the determined vehicle state. There is also providing information. In this case, the driving state information includes, for example, operating states of devices (brake pedal, accelerator pedal, parking brake device, steering wheel, transmission) operated by a driver of the vehicle, vehicle speed, vehicle position, vehicle Information corresponding to the surrounding situation can be adopted.

  In this case, more specifically, when the determined vehicle state is parked, the control means has complicated grammatical complexity in the converted character string data, and the complexity is predetermined. Provide converted information that is equal to or higher than the upper limit complexity, and when the determined vehicle state is driving, the grammatical complexity of the converted character string data is simple and the complexity Provides information after conversion that is equal to or less than a predetermined lower limit complexity, and when the determined vehicle state is stopped, the complexity of the converted character string data is greater than the predetermined upper limit side. It is possible to provide information after conversion that is smaller than the complexity and larger than the complexity on the predetermined lower limit side.

  According to these, the information of a more suitable aspect can be provided according to the vehicle state, that is, the state of the vehicle occupant (in particular, the driver) to which the information is provided. Specifically, when the vehicle is parked as a vehicle state, the vehicle occupant (especially the driver) can concentrate on understanding the content of the information provided, so the complexity is higher than the predetermined upper limit. It can be provided even if it is more than the complexity. On the other hand, when the vehicle is driving as a vehicle state, since the driver of the vehicle needs to concentrate on driving, only the simplified information whose complexity is equal to or lower than the complexity on the predetermined lower limit side is provided. be able to. Also, when the vehicle is stationary as a vehicle state, it is necessary for the driver of the vehicle to concentrate on driving quickly, so that the complexity is between a predetermined upper limit complexity and a lower limit complexity. It is possible to provide relatively simplified information that is complex. Therefore, in particular, useful information and information on the amount can be appropriately provided to the driving driver.

  Similarly to the main server 21, the message server 22 includes a control device 22a, a storage device 22b, and a communication interface 22c. Further, for example, the message information transmitted from the information terminal device 30 is temporarily stored in the storage device 22b of the mail server 22, and the character data converted by the control device 21a of the main server 21 as described later is used. A message information database 22d for temporarily storing the converted message information. Here, the message information temporarily stored in the message information database 22d is stored in association with account information described later corresponding to the transmission destination. Thereby, in the message server 22, the control device 22a transmits the message information temporarily stored in the message information database 22d or the converted message information described later based on the address information indicating the destination included in the account information. It transmits to the previous vehicle-mounted terminal device 10. The communication device 23 is connected to the network 40 to realize communication with the in-vehicle terminal device 10 and the information terminal device 30.

  The connection ID information stored in the vehicle registration database 24, the account information (or user ID information) stored in the user account registration information database 25, and the contractor information stored in the contractor information management database 26 Of these, the contractor information corresponding to the user (driver) of the vehicle is stored in association with each other. Thereby, the main server 21 can acquire other corresponding information based on one of these pieces of information.

  Furthermore, a character string data conversion database 27 is constructed in the service providing center 20. The character string data conversion database 27 is connected to a communication line constructed in the service providing center 20 and can be accessed from the main server 21. The character string data conversion database 27 converts the complexity determination table for determining the complexity representing the grammatical complexity in the character string data of the received message information, and converts the character string data into converted character string data described later. A character data conversion procedure table that defines the procedure is stored in advance or in an updatable manner.

  As shown in FIG. 4, the information terminal device 30 includes an input unit 31, a display unit 32, an electronic control unit 33, a storage unit 34, a communication unit 35, and a GPS unit 36 that are communicably connected to each other.

The display unit 32 includes, for example, a liquid crystal display, and displays characters, graphics, and the like on the display panel.

  The electronic control unit 33 is a microcomputer including a CPU, a ROM, a RAM, and the like. For example, by executing a known program (for example, a browser application program) for using the SNS, the input unit 31, the display unit 32, and the storage The operations of the unit 34 and the communication unit 35 are comprehensively controlled to transmit and receive message information. The storage unit 34 stores various programs including the browser application program described above, and account information (ID information, password information, etc.) necessary for accessing the message server 22 of the service providing center 20 when transmitting / receiving message information. . The communication unit 35 is connected to the network 40 to realize a function of transmitting / receiving message information to / from the service providing center 20. The GPS unit 36 receives radio waves from GPS satellites and detects the position of the information terminal device 30.

  Here, as the information terminal device 30, specifically, a mobile phone such as a smartphone, a tablet information terminal, a laptop personal computer, or the like can be employed. In this case, for example, it goes without saying that a desktop personal computer installed at home or the like can be employed. Further, in principle, the message information transmitted from the information terminal device 30 using the SNS includes the position of the information terminal device 30 detected by the GPS unit 36, in other words, the position indicating the position where the message information is transmitted. Contains information.

  Next, the operation of the first embodiment configured as described above will be described with reference to a functional block diagram. As shown in FIG. 5, the main server 21 of the service providing center 20 in the present embodiment includes an information acquisition unit 51, a complexity determination unit 52, a character string data conversion unit 53, and a message information provision unit 54. An information providing unit 50 is provided.

  The information acquisition unit 51 as information acquisition means acquires vehicle position information and message information. Specifically, the information acquisition unit 51 receives and acquires position information transmitted from the in-vehicle terminal device 10 of the vehicle via the network 40 using the communication device 23. Here, in the in-vehicle terminal device 10, the electronic control unit 11 acquires position information representing the position of the vehicle detected by the GPS unit 15 at a predetermined frequency. Then, the electronic control unit 11 outputs the acquired position information to the communication unit 12 together with the connection ID information and the connection password information. Accordingly, the communication unit 12 transmits the position information, the connection ID information, and the connection password information to the service providing center 20 via the network 40.

  Further, the information acquisition unit 51 receives message information transmitted from the information terminal device 30 in association with account information corresponding to connection ID information acquired from the vehicle side from the message server 22 of the service providing center 20 together with the position information. get. That is, the information acquisition unit 51 supplies account information associated with the acquired connection ID information to the control device 22a of the message server 22 and requests provision of message information associated with the account information. The control device 22a of the message server 22 searches the message information database 22d using the supplied account information, and extracts the target message information from the message information temporarily stored in the message information database 22d. And get. Then, the control device 22a outputs the acquired message information to the information acquisition unit 51. As described above, when the vehicle position information and message information are acquired, the information acquisition unit 51 outputs the acquired message information to the complexity determination unit 52 and the acquired vehicle position information to the character string data conversion unit 53. Output.

  In the complexity determination unit 52 as the complexity determination unit, the complexity representing the grammatical complexity in the character string data of the message information acquired from the information acquisition unit 51 is determined. For this reason, the complexity determination unit 52 searches the character string data conversion database 27 and acquires, for example, a complexity determination table as shown in FIG. Then, the complexity determination unit 52 converts the message information acquired by the information acquisition unit 51 based on the complexity determination table into the number of sentences (sentences), the number of double negations, the number of connected words, the number of modifiers, and the sentences (sentences). Each long item is converted into points, and the complexity is analyzed and determined according to the number of points.

  Specifically, the complexity determination unit 52 analyzes the number of sentences based on, for example, the number of phrases in the character string data of the message information. Then, according to the complexity determination table shown in FIG. 6, for example, if the analyzed sentence number is “1”, the point is set to “1”, and if the sentence number is “2”, the point is set to “3”. If the number of sentences is “3” or more, the point is set to “5”. That is, the complexity determination unit 52 increases the number of points as the number of sentences increases and the character string data of the message information, in other words, the message (tweet) or e-mail provided to the vehicle driver (user) becomes more complicated. Set a larger value.

  Further, the complexity determination unit 52 decomposes the character string data of the message information, for example, for each phrase (word), compares the decomposed phrase (word), and determines the double negation included in the character string data. To analyze. For example, if the number of double negations included in the character string data of the message information is “1”, the complexity determination unit 52 sets the point to “3” and includes the double negation included. If the number of points is “2”, the point is set to “5”, and if the number of double negations included is “3” or more, the point is set to “7”. That is, the complexity determination unit 52 increases the number of double negations, so that the character string data of the message information, in other words, the message (tweet) provided to the vehicle driver (user) and the content of the e-mail are instantaneous. The point number is set larger as it becomes difficult to understand (complicated).

  Further, the complexity determination unit 52 analyzes the connected words included in the disassembled clause (word). Then, for example, the complexity determination unit 52 sets the point to “3” if the analyzed number of connected words is “1”, and sets the point to “5” if the number of connected words is “2”. If the number of connected words is “3” or more, the point is set to “7”. That is, the complexity determination unit 52 increases the number of connected words, and the character string data of the message information, in other words, the message (tweet) provided to the vehicle driver (user) and the content of the e-mail are instantaneous. Set the number of points larger as it becomes difficult to understand (complicated).

  Similarly, the complexity determination unit 52 analyzes the modifier included in the decomposed clause (word). Then, for example, the complexity determining unit 52 sets the number of points to “1” if the number of analyzed modifiers is “1”, and sets the number of points to “3” if the number of modifiers is “2”. If the number of modifiers is “3” or more, the number of points is set to “5”. In other words, the complexity determination unit 52 increases the number of modifiers, and the text data of the message information, in other words, messages (tweets) and e-mails provided to the vehicle driver (user) are redundant. The larger the number of points, the higher the number of points.

  Furthermore, the complexity determination unit 52 analyzes the sentence length based on the number of decomposed clauses (words) in the character string data of the message information. Then, for example, if the number of phrases (words) is not more than “3” as the sentence length, the complexity determining unit 52 sets the number of points to “1”, and the number of phrases (words) as the sentence length is “4” to “4”. If it is “10”, the number of points is set to “3”, and if the number of phrases (words) is “11” or more as the sentence length, the number of points is set to “5”. That is, the complexity determination unit 52 increases the number of clauses (words) and lengthens the sentence length, so that the character string data of the message information, in other words, the message (tweet) provided to the driver (user) of the vehicle, The point number is set to be larger as the content in the e-mail becomes redundant (complex).

  As described above, when the complexity determination unit 52 sets the number of points according to the number of sentences, the number of double negations, the number of connected words, the number of modifiers, and the sentence length, Add the number of points to calculate the total number of points. Then, the complexity determination unit 52 outputs total point information indicating the total number of points and message information corresponding to the total point information to the character string data conversion unit 53.

  In the character string data conversion unit 53 as the character string data conversion means, the character string data of the message information is converted so that the total points become small based on the total point information acquired from the complexity determination unit 52. That is, the character string data conversion unit 53 performs real-time processing on message information having a large total number of points, in other words, message information that is grammatically complex and difficult to understand quickly, even when the driver is driving the vehicle. The character string data of the message information is converted so that it can be provided (specifically, the total number of points is “5” or less).

  For this reason, the character string data conversion unit 53 searches the character string data conversion database 27 and acquires, for example, a character string data conversion procedure table as shown in FIG. As will be described later, the character string data conversion unit 53 also searches the character string data conversion database 27 to obtain the complexity determination table shown in FIG. 6 in order to set the number of points of the converted character string data. It is supposed to be. Then, the character string data conversion unit 53, among the message information acquired through the complexity determination unit 52, in accordance with the procedure and conversion content determined by the character string data conversion procedure table, in particular, the associated total point information Is converted so that the total number of points is equal to or less than “5”. In this case, for the message information whose total number of points is already “5” or less, the character string data conversion unit 53 outputs the message information to the message information providing unit 54 without changing the character string data.

  Specifically, first, the character string data conversion unit 53 follows the operation execution order 1 of the character string data conversion procedure table shown in FIG. 7 and within a specific range in which the message information transmission source is set in advance. It is determined whether or not the message is transmitted from. That is, the character string data conversion unit 53 refers to, for example, header information included in the message information, contractor information associated with the message information, and the like so that the transmission source of the message information is within a specific range (for example, If the user is a third party friend set in advance, the operation execution order 2 is executed. On the other hand, the character string data conversion unit 53 is less urgent if the source of the message information is out of a specific range (for example, forwarded message information or message information representing an advertisement). End conversion. In this case, for example, when the vehicle is parked, message information is provided to the driver.

  When the character string data decomposed for each clause (word) includes double negation according to the operation execution order 2 of the character string data conversion procedure table shown in FIG. The character string data (sentence (word)) is converted so that the character string data of the negative part (sentence (word)) becomes affirmative. Then, in the converted character string data in which the corresponding character string data is converted in this way, it is decomposed again for each phrase (word), and the number of points is set for each item according to the complexity determination table shown in FIG. If the calculated total number of points is equal to or less than “5”, the character string data conversion unit 53 outputs converted message information including the converted character string data to the message information providing unit 54. On the other hand, even in the converted character string data obtained by converting the character string data of the double negative part so as to be affirmative, if the total number of points does not become “5” or less, the character string data conversion unit 53 changes the operation execution order 3. Run.

  The character string data conversion unit 53 includes a modifier in character string data (or converted character string data) decomposed for each clause (word) in accordance with the operation execution order 3 of the character string data conversion procedure table shown in FIG. For example, instead of deleting the first half or the latter half of the character string data completely as in the case of the conventional vehicle-mounted device described above, only the character string data (sentence (word)) of the modifier part is deleted. Then, the character string data is converted so that the sentence length is shortened. Then, in the converted character string data from which the character string data (phrase (word)) of the modifier portion is deleted in this way, each item (phrase (word)) is decomposed again for each item according to the complexity determination table shown in FIG. If the total number of points calculated by setting the number of points is less than or equal to “5”, the character string data conversion unit 53 outputs the converted message information to the message information providing unit 54. On the other hand, even in the converted character string data from which the character string data of the modifier part (sentence (word)) is deleted, if the total number of points does not become “5” or less, the character string data conversion unit 53 sets the operation execution order 4. Run.

  When the character string data conversion unit 53 disassembles each phrase (word) in the character string data (or converted character string data) of the message information in accordance with the operation execution order 4 of the character string data conversion procedure table shown in FIG. Deletes sentences that do not contain nouns and converts character string data. Then, in the converted character string data from which sentences that do not include nouns are deleted in this way, each sentence (word) is decomposed again, and the number of points is set for each item according to the complexity determination table shown in FIG. If the total number of points obtained is equal to or less than “5”, the character string data conversion unit 53 outputs the converted message information to the message information providing unit 54. On the other hand, even in the converted character string data from which the sentence not including the noun is deleted, the character string data converting unit 53 executes the operation execution order 5 unless the total number of points is “5” or less.

  The character string data conversion unit 53 follows the operation execution order 5 of the character string data conversion procedure table shown in FIG. 7, and when the character string data (or converted character string data) of the message information is decomposed into phrases (words). The text data is converted by deleting sentences that contain nouns but do not contain nouns (frequent nouns) that frequently appear in the text data as specific nouns. Here, as a frequent noun, for example, it can be a noun that a vehicle occupant (driver) is interested in and has sent message information to the outside in the past. It is good to preferentially extract from the above by filtering. Then, in the converted character string data from which sentences that do not include frequent nouns are deleted as described above, each sentence (word) is decomposed again, and points are set for each item according to the complexity determination table shown in FIG. If the calculated total number of points is equal to or less than “5”, the character string data conversion unit 53 outputs the converted message information to the message information providing unit 54. On the other hand, even in the converted character string data from which sentences without frequent nouns are deleted, the character string data converting unit 53 executes the operation execution order 6 if the total number of points does not become “5” or less.

  The character string data conversion unit 53 follows the operation execution order 6 of the character string data conversion procedure table shown in FIG. 7, and the position where the message information is transmitted (that is, the contractor (friend etc.) who is the third party who transmitted the message information. ))) And the position of the vehicle are both within a certain range, the message information (or conversion message information) is converted into character string data consisting of a minimum number of words. Specifically, the character string data conversion unit 53 includes the position information included in the message information and the contractor information associated with the message information, and the vehicle position acquired from the in-vehicle terminal device 10 by the information acquisition unit 51. Get information and. Then, the character string data conversion unit 53 first determines, based on the position information included in the message information and the position information of the vehicle, the position where the message information is transmitted (that is, the contractor (friend who transmitted the message information) Or the like) and the position of the vehicle are both determined within a certain range.

  If it is determined that the contractor and the vehicle are within a certain range, the character string data conversion unit 53 specifies the contractor (such as a friend) who transmitted the message information using the contractor information. For example, nouns (including frequent nouns) constituting character string data of message information are extracted. Then, the character string data conversion unit 53, for example, has been transmitted by generating character string data in which the extracted noun (frequent noun) is added to the character string data “Mr. XX is nearby”. The character string data of the message information is converted, and the generated character string data is used as converted character string data.

  That is, in this operation execution order 6, since there is a contractor (friend, etc.) who is a third party who has transmitted the message information nearby, for example, the driver of the vehicle can easily meet the contractor directly. Is possible. For this reason, in this operation execution order 6, since the character string data provided to the driver of a vehicle should mainly transmit that the contractor exists nearby, the detailed contents are excluded. Provided with coarser granularity of information. Here, the conversion character string data generated in this way is generated so that the total number of points becomes “5” or less. For this reason, the character string data conversion unit 53 outputs the conversion message information to the message information providing unit 54. On the other hand, if the contractor and the vehicle do not exist within a certain range according to the determination, the character string data conversion unit 53 executes the operation execution order 7.

  The character string data conversion unit 53 follows the operation execution order 7 of the character string data conversion procedure table shown in FIG. 7, and the position where the message information is transmitted (that is, the position of the contractor who is the third party who transmitted the message information). Message information (or converted message information) is converted into character string data consisting of a minimum number of words. Specifically, the operation execution order 7 is the case where the contractor and the vehicle do not exist within a certain range in the operation execution order 6 described above, that is, when the contractor and the vehicle exist outside the certain range. Executed. Therefore, the character string data conversion unit 53 generates, in this operation execution order 7, for example, character string data obtained by adding the frequent noun extracted to the character string data “Message from Mr. XX”. The character string data of the transmitted message information is converted, and the generated character string data is used as converted character string data.

  That is, in this operation execution order 7, unlike the operation execution order 6, the contractor is present at a distant position. Therefore, for example, the conversion message information (character string data) provided by the vehicle driver facilitates the operation. In addition, it is necessary to be able to grasp the contents of the message information transmitted by the contractor promptly. Therefore, in this case, by adding frequent nouns related to detailed contents, the granularity of information is provided more finely than the granularity of information in the operation execution order 6. Here, the conversion character string data generated in this way is generated so that the total number of points becomes “5” or less. For this reason, the character string data conversion unit 53 outputs the conversion message information to the message information providing unit 54.

  In this embodiment, every time the character string data conversion unit 53 converts character string data in accordance with the operation execution order of the character string data conversion procedure table shown in FIG. 7, the complexity determination table shown in FIG. The total number of points of the converted character string data is calculated according to the above. However, in this case, after the character string data conversion unit 53 converts the character string data as described above according to the operation execution order, the converted character string data, that is, the converted message information is output to the complexity determination unit 52 so as to return to the complexity determination unit 52. It goes without saying that the degree determination unit 52 can be implemented so as to calculate the total number of points of the converted character string data. In this case, when the complexity determination unit 52 calculates the total number of points of the converted character string data, it can output the converted message information together with the converted total point information to the character string data converting unit 53. Thereby, as described above, the character string data conversion unit 53 can convert the character string data (more specifically, the converted character string data converted according to the previous execution order) according to the next operation execution order.

  In the message information providing unit 54 as information providing means, the conversion message information (or message information that does not require conversion) output from the character string data conversion unit 53 is provided to the in-vehicle terminal device 10. That is, the message information providing unit 54 supplies the output converted message information (or message information that does not require conversion) to the message server 22. In the message server 22, the supplied converted message information (or message information that does not require conversion) is temporarily stored in the message information database 22 d and then transmitted to the in-vehicle terminal device 10 via the network 40. Thereby, in the in-vehicle terminal device 10, the electronic control unit 11 is provided from the message server 22 of the service providing center 20 (more specifically, the message information providing unit 54 of the main server 21) via the communication unit 12. Receives and acquires converted message information (or message information that does not require conversion). Then, the electronic control unit 11 supplies the acquired conversion message information (or message information that does not require conversion) to the notification unit 14. Thereby, the notification unit 14 displays the character string data represented by the conversion message information (or message information that does not need to be converted) on the screen of the display display, or corresponds to the character string data through the speaker. A sound to be output is notified to the driver of the vehicle.

  As can be understood from the above description, according to the first embodiment, when message information including character string data is transmitted from the external information terminal device 30 to the driver of the vehicle, the service providing center 20 main The server 21 (information providing unit 50) determines the complexity representing the grammatical complexity in the character string data of the message information, and the grammatical complexity in the character string data is determined according to the determined complexity. The transmitted character string data can be converted to be simple. Then, the converted message information including the converted character string data converted so as to be simplified can be provided to the in-vehicle terminal device 10, that is, the driver of the vehicle. Accordingly, since a part of the character string data included in the message information is not simply deleted, the amount of information provided by the converted message information does not become insufficient. Moreover, since the grammatical complexity can be eliminated, the contents of the conversion message information including the simplified conversion character string data can be easily understood. Thus, for example, when the conversion message information is provided to the driving driver, the driver can understand the content of the transmitted information very well, and the useful content and amount of information can be displayed. Can be provided appropriately.

b. Second Embodiment In the first embodiment, the main server 21 of the service providing center 20 is directed toward the in-vehicle terminal device 10 of the vehicle, in other words, toward the vehicle occupant (driver). Implemented to convert message information (character string data) transmitted from the information terminal device 30 and provide converted message information (converted character string data) so that message information can be provided in real time even while driving. did. As a result, for example, it is possible to provide the minimum necessary information to a driver who is driving the vehicle without disturbing the driving. In this case, the conversion message information can be provided according to the complexity of the conversion message information and the state of the vehicle driven by the driver. Hereinafter, although this 2nd Embodiment is described in detail, the same code | symbol is attached | subjected to the same part as the said 1st Embodiment, and the detailed description is abbreviate | omitted.

  In the second embodiment, the in-vehicle terminal device 10 mounted on the vehicle includes a communication interface 16 as indicated by a broken line in FIG. . The communication interface 16 realizes communication between various sensors (not shown) mounted on the vehicle and the electronic control unit 11. Here, as various sensors, for example, a vehicle speed sensor that detects the vehicle speed of a vehicle, a steering angle sensor that detects a steering angle that is an operation amount of a steering wheel (not shown), and a brake pedal that detects whether or not a brake pedal (not shown) is operated. Examples include a sensor, an accelerator pedal sensor that detects whether or not an accelerator pedal (not shown) is operated, a parking brake sensor that detects whether or not a parking brake device (PKB) is not shown.

  Further, in the service providing center 20 in the second embodiment, the character string data conversion database 27 includes, in addition to the complexity determination table and the character string data conversion procedure table described above, a vehicle equipped with the in-vehicle terminal device 10. Based on the driving state information indicating the driving state, a vehicle state determination table for determining a vehicle state in which the vehicle is parked, stopped, or driving (running) is stored in advance or updatable. ing. Thereby, the main server 21 of the service providing center 20 can obtain the vehicle state determination table by searching the character string data conversion database 27.

  And in this 2nd Embodiment, the main server 21 of the service provision center 20 is provided with the vehicle state determination part 55 which comprises the information provision part 50, as shown in FIG. Hereinafter, the operation of the information providing unit 50 in the second embodiment will be described in detail.

  In the second embodiment, the information acquisition unit 51 acquires message information from the message information database 22d of the message server 22 and also obtains the driving state information of the vehicle from the in-vehicle terminal device 10 as in the first embodiment. get. Specifically, the information acquisition unit 51 receives and acquires the driving state information transmitted from the in-vehicle terminal device 10 of the vehicle via the network 40 using the communication device 23. Here, in the in-vehicle terminal device 10, the electronic control unit 11 performs, for example, the vehicle speed obtained from the vehicle speed sensor and the presence / absence of operation of the brake pedal obtained from the brake pedal sensor via the communication interface 16 in a predetermined cycle. Then, the parking brake device (PKB) obtained from the parking brake sensor is obtained, the accelerator pedal operation obtained from the accelerator pedal sensor is obtained, and the steering angle of the steering wheel obtained from the steering angle sensor is obtained. Then, the electronic control unit 11 uses the acquired various physical quantities as vehicle driving state information, and outputs it to the communication unit 12 together with the connection ID information and the connection password information. As a result, the communication unit 12 transmits the operation state information, the connection ID information, and the connection password information to the service providing center 20 via the network 40.

  In the main server 21 of the service providing center 20, the information acquisition unit 51 of the information providing unit 50 acquires vehicle driving state information. Then, the information acquisition unit 51 outputs the acquired driving state information of the vehicle to the vehicle state determination unit 55.

  In the vehicle state determination unit 55 as the vehicle state determination unit, the vehicle is parked, stopped, or driving (running) based on the vehicle driving state information acquired from the information acquisition unit 51. The vehicle state is determined to be medium). For this reason, the vehicle state determination part 55 searches the character string data conversion database 27, for example, acquires a vehicle state determination table as shown in FIG. Then, the vehicle state determination unit 55 uses the vehicle driving state information and the vehicle state determination table to provide (transmit) the message information, the vehicle state of the vehicle on which the in-vehicle terminal device 10 is mounted, in other words, the driver. The state of is determined.

  More specifically, now, among the physical quantities represented by the driving state information of the vehicle, the vehicle speed is “0”, the parking brake device (PKB) is operated (ON state), the accelerator If the pedal is not operated (OFF state) and the parking brake device (PKB) is on for a certain time, the vehicle state determination unit 55 determines that the vehicle is “parked” based on the vehicle state determination table. Judge that there is. In addition, among the physical quantities represented by the driving state information of the vehicle, the vehicle speed is “0”, the brake pedal is operated (ON state), the accelerator pedal is not operated (OFF state), the steering If the steering angle of the wheel is “0”, that is, if the rotation operation position is the neutral position, the vehicle state determination unit 55 determines that the vehicle is “stopped” based on the vehicle state determination table. Further, among the physical quantities represented by the vehicle running state information, the vehicle speed is not “0”, or the vehicle speed is “0”, the brake pedal is operated (ON state), and the accelerator pedal is If not operated (OFF state) and the steering angle of the steering wheel is not “0”, that is, if the rotational operation position is not a neutral position (specifically, waiting for a right turn at an intersection, etc.), a vehicle state determination unit 55 determines that the vehicle is “driving” based on the vehicle state determination table. When the vehicle state determination unit 55 determines any one of “parking”, “stopped”, and “driving” as the vehicle state, the vehicle state determination information indicating the determination result is displayed as a message. The information is output to the information providing unit 54.

  In the second embodiment, the character string data conversion unit 53 converts character string data in accordance with the character string data conversion procedure table shown in FIG. 7 as in the first embodiment. 6 and 7 are omitted. That is, the character string data conversion unit 53 in the second embodiment performs character string data (or conversion message information) of message information (or conversion message information) according to the operation execution order 1 to 5 of the character string data conversion table shown in FIG. Conversion character string data). Then, the character string data conversion unit 53 in the second embodiment outputs the converted message information converted in the same manner as in the first embodiment to the message information providing unit 54, and calculates the converted character string data converted. The converted total point information indicating the number of points is output to the message information providing unit 54. As described in the first embodiment, when the converted character string data converted according to the operation execution order 2 to 4 is output to the message information providing unit 54, the total number of points becomes “5” or less. Limited to For this reason, in this case, outputting the converted total point information can be omitted.

  The message information providing unit 54 according to the second embodiment includes a vehicle state represented by the converted total point information output from the character string data conversion unit 53 and the vehicle state determination information output from the vehicle state determination unit 55 ( That is, conversion message information (or message information before conversion) is provided to the in-vehicle terminal device 10 based on “parking”, “stopped”, or “driving”). Hereinafter, this provision will be specifically described.

  The message information providing unit 54 converts, for example, when the total number of points represented by the converted total point information (or the total point information before conversion) is equal to or less than “5” points, which is a predetermined lower limit side complexity. Character string data (or character string data that does not need to be converted) is not complicated, and even if conversion message information (or message information that does not need to be converted) is provided to the driver during driving, the influence on the driving operation is small. Therefore, when the total number of points is “5” or less, the message information providing unit 54 is the same as in the first embodiment even if the vehicle state determined by the vehicle state determination unit 55 is “driving”. In addition, conversion message information (or message information that does not require conversion) is provided to the in-vehicle terminal device 10. When the total number of points is “5” or less, the message information providing unit 54 also converts the converted message information (when the vehicle state is determined to be “stopped” or “parked” by the vehicle state determination unit 55). It goes without saying that message information that does not require conversion can be provided to the in-vehicle terminal device 10.

  For example, when the total number of points represented by the converted total point information is “6” to “10” or less, the message information providing unit 54 converts the converted character string data (or character string data that does not require conversion). ) Is slightly complicated but can be understood relatively quickly. For this reason, when the total number of points is “6” to “10” or less, the message information providing unit 54 determines that the vehicle state determined by the vehicle state determination unit 55 is other than “Driving”, that is, “Stopped”. (Or “parking”), conversion message information (or message information that does not require conversion) is provided to the in-vehicle terminal device 10.

  Furthermore, for example, when the total number of points represented by the converted total point information is equal to or greater than “11”, which is the complexity on the predetermined upper limit side, the message information providing unit 54 has complicated conversion character string data, Difficult to understand promptly. Therefore, when the total number of points is “11” or more, the message information providing unit 54 sends the converted message information to the in-vehicle terminal only when the vehicle state determined by the vehicle state determination unit 55 is “parking”. Provided to the apparatus 10.

  As can be understood from the above description, according to the second embodiment, a vehicle occupant who uses the in-vehicle terminal device 10 provided with vehicle status, in other words, conversion message information (message information that does not require conversion) is provided. In particular, the conversion message information (message information) can be provided in a more appropriate manner according to the state of the driver. That is, when the vehicle is parked as a vehicle state, the driver of the vehicle can concentrate on understanding the contents of the provided conversion message information (message information that does not need to be converted). It can be provided even when the complexity is equal to or higher than the upper limit complexity (for example, the total number of points is “11” or more). On the other hand, when the vehicle is driving as a vehicle state, the driver of the vehicle needs to concentrate on driving in particular, so the complexity is equal to or less than a predetermined lower limit complexity (for example, the total number of points is “5” or less). Only simplified conversion message information can be provided. Further, when the vehicle is stopped as a vehicle state, in particular, since the driver of the vehicle needs to concentrate on driving promptly, the complexity is a complexity on the predetermined upper limit side (for example, the total point is “11”). And relatively simple conversion message information (message information that does not require conversion) having a complexity between the lower limit side complexity (for example, the total point is “5”) can be provided. Therefore, in particular, useful information and information on the amount can be appropriately provided to the driving driver.

  In the second embodiment, when the vehicle state determination unit 55 determines the vehicle state, the vehicle speed, whether or not the brake pedal is operated, whether or not the parking brake device (PKB) is operated, whether or not the accelerator pedal is operated, and the steering wheel It was carried out based on the steering angle. In this case, in addition to these, for example, the vehicle state can be determined based on the position of the vehicle detected by the GPS unit 15.

  Specifically, in this case, the vehicle state determination table is changed as shown in FIG. Then, according to the vehicle state determination table, the vehicle state determination unit 55 has a vehicle speed of “0”, the parking brake device (PKB) is operated (ON state), and the accelerator pedal is not operated (OFF) State), the parking brake device (PKB) has been turned on for a certain period of time, and if the position of the vehicle detected by the GPS unit 15 is located outside the road, the vehicle is It is determined that it is “medium”. Further, according to the vehicle state determination table, the vehicle state determination unit 55 has a vehicle speed of “0”, the brake pedal is operated (ON state), the accelerator pedal is not operated (OFF state), and the steering wheel In addition to the steering angle of “0”, if the position of the vehicle detected by the GPS unit 15 is located on the road, it can be determined that the vehicle is “stopped”. . As a result, the vehicle state can be determined more accurately, and the same effect as in the second embodiment can be obtained.

  When the communication interface 16 can realize communication with a shift position sensor that detects (acquires) a shift position of a transmission (not shown), a shift position detected by the shift position sensor or a shift by a driver. It can also be implemented so as to determine the vehicle state based on a change in position. That is, in this case, when the shift position is set to “parking (P)” by the driver, the vehicle state can be determined to be “parking”. Alternatively, in this case, after the shift position is repeatedly changed between “drive (D)” and “reverse (R)” by the driver, it is set to “parking (P)” or “neutral (N)”. Sometimes, the vehicle state can be determined as “parking”. Thereby, also in this case, since the vehicle state can be determined with higher accuracy, the same effect as in the second embodiment can be obtained.

  Further, when the communication interface 16 can realize communication with an image sensor (on-vehicle camera) or a radar sensor that detects (acquires) a situation around the vehicle, it is detected by the image sensor or the radar sensor. The vehicle state can also be determined based on the situation around the vehicle. That is, in this case, the vehicle state can be accurately determined as “parking”, “stopped”, or “driving” based on the situation around the vehicle. Thereby, also in this case, since the vehicle state can be determined with higher accuracy, the same effect as in the second embodiment can be obtained. In this case, the complexity (specifically, the total number of points) of the character string data that can be provided when the vehicle state is “driving” is increased or decreased based on the situation around the vehicle. Can also be changed. As a result, it is possible to more suitably provide information of contents and amount appropriate for the driver.

  For example, in each of the above embodiments, the main server 21 of the service providing center 20 is provided with the information providing unit 50. In this case, for example, the electronic control unit 11 of the in-vehicle terminal device 10 can be implemented so as to include the information providing unit 50. Even in this case, the information providing unit 50 can provide the conversion message information (or message information that does not require conversion) optimized according to the complexity of the character string data to the vehicle occupant (driver). Therefore, it is possible to provide information of contents and amount appropriate for the driver, and the same effects as those of the above embodiments can be obtained.

  Moreover, in each said embodiment, it implemented so that conversion message information (or message information) might be provided via the alerting | reporting unit 14 of the vehicle-mounted terminal device 10 with respect to the driver of a vehicle. In this case, for example, conversion message information (or message information that does not need to be converted) is provided via a display panel provided in a smartphone (mobile phone) or tablet terminal possessed by a vehicle driver or passenger. It is also possible to carry out. In this case, the in-vehicle terminal device 10 and a smart phone (mobile phone), a tablet terminal, etc. brought into the vehicle can be preliminarily short-distance wirelessly communicated with, for example, Bluetooth (registered trademark) or Wi-Fi (registered trademark). Connect (pair) to. Thereby, for example, when the in-vehicle terminal device 10 acquires conversion message information (message information that does not require conversion) from the service providing center 20, the electronic control unit 11 uses the acquired conversion message information (message information that does not require conversion). It can be supplied to a smartphone (mobile phone), a tablet terminal, or the like using short-range wireless communication. Therefore, a smartphone (mobile phone), a tablet terminal, or the like can display supplied conversion message information (message information that does not need to be converted) on, for example, a display panel to notify a vehicle driver or passenger. The same effects as those in the above embodiments can be obtained.

  In each of the above embodiments, for example, the communication unit 12 of the in-vehicle terminal device 10 receives conversion message information (message information that does not require conversion) from the service providing center 20 via the network 40 such as a mobile phone network. Implemented to get. In this case, the communication unit 12 of the in-vehicle terminal device 10 acquires conversion message information (message information that does not need to be converted) using Wi-Fi (registered trademark) communication, road-to-vehicle communication, vehicle-to-vehicle communication, or the like. It is also possible to implement. In this case, instead of the GPS unit 15 detecting the position of the vehicle, the position information is acquired using Wi-Fi (registered trademark) communication, road-to-vehicle communication, vehicle-to-vehicle communication, or the like. It is also possible to carry out. Also by these, effects equivalent to those of the above embodiments can be expected.

  Further, in each of the above embodiments, the complexity determination unit 52 sets the number of points for all items set in the complexity determination table shown in FIG. In this case, it is also possible to set the point number of at least one item among all items set in the complexity determination table shown in FIG. 6 so as to simply determine the complexity. Further, in each of the above embodiments, the character string data conversion unit 53 is performed so as to perform the entire operation execution order set in the character string data conversion procedure table shown in FIG. In this case, the character string data is simply converted by executing at least one operation in the entire operation execution order set in the conversion procedure table with the character string shown in FIG. Is also possible.

  Further, in the second embodiment, the character string data conversion unit 53 is provided. In this case, the character string data conversion unit 53 may be omitted. That is, in this case, when the complexity determination unit 52 analyzes the complexity of the character string data of the message information and calculates the total number of points, the total point information and the message information are directly transmitted to the message information providing unit 54. Is output. Thereby, for example, when the total number of points represented by the total point information output by the complexity determination unit 52 is “5” or less, the message information providing unit 54 determines the vehicle determined by the vehicle state determination unit 55. The message information can be provided to the in-vehicle terminal device 10 even if the state is “Driving”. In addition, when the total number of points is “6” to “10” or less, the message information providing unit 54 displays the message information when the vehicle state is “stopped” (or “parked”). 10 can be provided. Further, when the total number of points is “11” or more, the message information providing unit 54 can provide the message information to the in-vehicle terminal device 10 only when the vehicle state is “parking”.
