The in-vehicle navigation device 10 performs route guidance from the current position to the destination based on a user request. The in-vehicle navigation device 10 also has a function of positioning position information of the in-vehicle navigation device 10 (that is, position information of the vehicle 60a). The position information measured by the in-vehicle navigation device 10 is appropriately transmitted to the information analysis device 30.
The vehicle-mounted navigation device 10 can be realized by a car navigation device that can be installed and portable on a vehicle 60a that is a mobile body, or a PND (Portable Navigation Device) that is simply installed on the vehicle 60a that is a mobile body.

Moreover, in the following description, when calling the vehicle 60a in which the vehicle-mounted navigation device 10 is mounted or the vehicle 60b on which the user using the mobile terminal 20 gets on without distinction, the alphabet at the end is simply omitted, This is called “vehicle 60”.
　情報分析装置３０は、本実施形態特有の処理である、移動体ユーザの訪問した施設と当該移動体ユーザの生活拠点との距離に基づいて当該移動体ユーザの嗜好の分析処理を行う装置である。情報分析装置３０は、車載ナビゲーション装置１０や携帯端末２０から、各車両６０の位置情報を取得することにより、各車両６０の位置情報についてのデータベースである位置情報データベースを作成する。そして、情報分析装置３０は、作成した位置情報データベースを統計的に分析することにより、各車両６０それぞれについて、訪問した訪問施設、当該ユーザの生活拠点、両者の距離、訪問回数等を特定する。 The information analysis apparatus 30 is an apparatus that performs a process of analyzing the preference of the mobile user based on the distance between the facility visited by the mobile user and the living base of the mobile user, which is a process specific to the present embodiment. . The information analysis device 30 acquires the position information of each vehicle 60 from the in-vehicle navigation device 10 and the portable terminal 20, thereby creating a position information database that is a database for the position information of each vehicle 60. Then, the information analysis apparatus 30 statistically analyzes the created location information database, thereby specifying the visited facility visited, the user's living base, the distance between the two, the number of visits, and the like for each vehicle 60.
　また、情報分析装置３０は、特定した訪問施設、当該ユーザの生活拠点、両者の距離、訪問回数等に基づいて、訪問施設の属するカテゴリーに関連する当該ユーザのユーザプロファイルを作成する。作成されたユーザプロファイルに基づいて、当該カテゴリーに関連する施設の施設情報の配信先を決定し、施設情報を当該配信先に配信する。これら分析情報や分析条件の詳細な内容については後述する。情報分析装置３０は、例えば１つ以上のコンピュータから構成されるサーバシステムにより実現することができる。 In addition, the information analysis apparatus 30 creates a user profile of the user related to the category to which the visited facility belongs based on the identified visited facility, the user's living base, the distance between them, the number of visits, and the like. Based on the created user profile, the distribution destination of the facility information of the facility related to the category is determined, and the facility information is distributed to the distribution destination. The detailed contents of these analysis information and analysis conditions will be described later. The information analysis device 30 can be realized by a server system including, for example, one or more computers.
　通信網５０は、インターネットや携帯電話網といったネットワークや、これらを組み合わせたネットワークにより実現される。また、ネットワークの一部（例えば、情報分析装置３０と分析情報参照端末４０の間）に、ＬＡＮ（Local Area Network）が含まれていてもよい。 The communication network 50 is realized by a network such as the Internet or a mobile phone network, or a network combining these. Further, a LAN (Local Area Network) may be included in a part of the network (for example, between the information analysis apparatus 30 and the analysis information reference terminal 40).
　車両６０は、車載ナビゲーション装置１０や携帯端末２０のユーザが乗車する移動体である。車両６０は、例えば、四輪自動車、自動二輪車、自転車等により実現される。 The vehicle 60 is a moving body on which a user of the in-vehicle navigation device 10 or the mobile terminal 20 gets on. The vehicle 60 is realized by, for example, a four-wheeled vehicle, a motorcycle, a bicycle, or the like.
　＜車載ナビゲーション装置１０が備える機能ブロック＞
　次に、車載ナビゲーション装置１０が備える機能ブロックについて図２のブロック図を参照して説明をする。
　ここで、車載ナビゲーション装置１０は、車両６０ａから電源の供給を受けており、車両６０ａに乗車したユーザにより車両６０ａのイグニッションスイッチがオン（エンジンを始動）にされることによって自動起動する。そして、車載ナビゲーション装置１０は、車両６０ａに乗車したユーザにより車両６０ａのイグニッションスイッチがオフ（エンジンを停止）にされるまで稼働する。 <Functional blocks included in the in-vehicle navigation device 10>
Next, functional blocks provided in the in-vehicle navigation device 10 will be described with reference to the block diagram of FIG.
Here, the in-vehicle navigation device 10 is supplied with power from the vehicle 60a, and automatically starts when the ignition switch of the vehicle 60a is turned on (starts the engine) by the user who gets on the vehicle 60a. And the vehicle-mounted navigation apparatus 10 is operated until the ignition switch of the vehicle 60a is turned off (the engine is stopped) by the user who gets on the vehicle 60a.
　図２に示すように、車載ナビゲーション装置１０は、制御部１１と、記憶部１２と、通信部１３と、センサ部１４と、表示部１５と、入力部１６とを含んで構成される。 As shown in FIG. 2, the in-vehicle navigation device 10 includes a control unit 11, a storage unit 12, a communication unit 13, a sensor unit 14, a display unit 15, and an input unit 16.
　制御部１１は、マイクロプロセッサ等の演算処理装置から構成され、車載ナビゲーション装置１０を構成する各部の制御を行う。制御部１１の詳細については、後述する。 The control unit 11 includes an arithmetic processing device such as a microprocessor, and controls each unit constituting the in-vehicle navigation device 10. Details of the control unit 11 will be described later.
　記憶部１２は、半導体メモリ等で構成されており、ファームウェアやオペレーティングシステムと呼ばれる制御用のプログラムや、経路案内処理を行うためのプログラムや、情報分析装置３０に対する位置情報の送信処理を行うためのプログラムといった各プログラム、さらにその他、地図情報等の種々の情報が記憶される。図中には、記憶部１２が記憶する情報として、位置情報の送信処理に特に関する情報である、位置情報１２１及び識別情報１２２を図示する。 The storage unit 12 is configured by a semiconductor memory or the like, and is used for performing a control program called firmware or an operating system, a program for performing route guidance processing, and transmission processing of position information to the information analysis device 30. Each program such as a program and various other information such as map information are stored. In the figure, as information stored in the storage unit 12, position information 121 and identification information 122, which are information related to the transmission process of position information, are illustrated.
　位置情報１２１は、後述のセンサ部１４により測位された車載ナビゲーション装置１０の位置情報（すなわち、車両６０ａの位置情報）である。位置情報１２１には、測位された位置を示す情報のみならず、測位を行った時刻も含まれるようにするとよい。
　また、識別情報１２２は、車載ナビゲーション装置１０を識別するための情報である。識別情報１２２としては、例えば車載ナビゲーション装置１０に一意に割り当てられた製造番号等を利用することができる。また、他にも、通信部１３が携帯電話網等のネットワークである通信網５０に接続するために、通信部１３に挿入されたＳＩＭ（Subscriber Identity Module）に付与された電話番号を識別情報１２２として利用することができる。また、他にも、車両６０ａに固有に付与されたＶＩＮ（車両識別番号）やナンバープレートの番号を識別情報１２２として利用することができる。 The position information 121 is position information of the in-vehicle navigation device 10 (that is, position information of the vehicle 60a) measured by the sensor unit 14 described later. The position information 121 may include not only information indicating the position where the position is determined, but also the time when the position is measured.
The identification information 122 is information for identifying the in-vehicle navigation device 10. As the identification information 122, for example, a serial number uniquely assigned to the in-vehicle navigation device 10 can be used. In addition, the telephone number assigned to the SIM (Subscriber Identity Module) inserted in the communication unit 13 in order for the communication unit 13 to connect to the communication network 50 such as a mobile phone network is used as the identification information 122. Can be used as In addition, a VIN (vehicle identification number) or a license plate number uniquely assigned to the vehicle 60 a can be used as the identification information 122.
　これらの記憶部１２に格納される各情報については、記憶部１２に予め記憶しておく構成としてもよいし、通信網５０に接続されたサーバ装置（図示を省略する。）等から必要に応じて適宜ダウンロードされる構成としてもよい。さらに、ユーザの入力等に応じて適宜修正されてもよい。 Each piece of information stored in the storage unit 12 may be stored in the storage unit 12 in advance, or as necessary from a server device (not shown) connected to the communication network 50. May be downloaded as appropriate. Furthermore, it may be appropriately modified according to user input or the like.
　通信部１３は、ＤＳＰ（Digital Signal Processor）等を有し、３Ｇ（3rd Generation）ＬＴＥ（Long Term Evolution）やＷｉ－Ｆｉ（登録商標）といった規格に準拠して、通信網５０を介して通信網５０を介した他の装置（例えば、情報分析装置３０）との間の無線通信を実現する。通信部１３は、例えば、後述の位置情報送信部１１２が、記憶部１２に格納されている位置情報１２１及び識別情報１２２を、情報分析装置３０に対して送信するために利用される。ただし、通信部１３と他の装置との間で送受信されるデータに特に制限はなく、位置情報１２１及び識別情報１２２以外の情報が送受信されるようにしてもよい。 The communication unit 13 includes a DSP (Digital Signal Processor) or the like, and is compliant with a standard such as 3G (3rd Generation) LTE (Long Term Evolution) or Wi-Fi (registered trademark) via the communication network 50. Wireless communication with other devices (for example, the information analysis device 30) via 50 is realized. For example, the communication unit 13 is used by a position information transmission unit 112 described later to transmit the position information 121 and the identification information 122 stored in the storage unit 12 to the information analysis device 30. However, data transmitted and received between the communication unit 13 and other devices is not particularly limited, and information other than the position information 121 and the identification information 122 may be transmitted and received.
　センサ部１４は、例えばＧＰＳ（Global Positioning System）センサ、ジャイロセンサ、加速度センサ等により構成される。センサ部１４は、位置情報を検出する位置検出手段としての機能を備え、ＧＰＳセンサによりＧＰＳ衛星信号を受信し、車載ナビゲーション装置１０の位置情報（緯度及び経度）を測位する。センサ部１４による測位は、上述したように所定の時間間隔（例えば３秒間隔）で行われる。測位した位置情報は、位置情報１２１として記憶部１２に格納される。
　なお、センサ部１４は、ジャイロセンサ、加速度センサにより測定される角速度や、加速度に基づいて車載ナビゲーション装置１０の位置情報の測位精度をさらに高めることも可能である。
　また、センサ部１４は、ＧＰＳ通信が困難又は不可能となった場合に、ＡＧＰＳ（Assisted Global Positioning System）通信を利用し、通信部１３から取得される基地局情報によって車載ナビゲーション装置１０の位置情報を算出することも可能である。
　なお、センサ部１４は前述したセンサを全て含む構成に限られない。例えば、前述したセンサは一部又は全部が車両６０ａの搭載する車載センサ（図示せず）に含まれるようにしてもよい。その場合、制御部１１は、車載センサからの信号を受信するようにしてもよいし、又は車両６０ａのＥＣＵ（Electronic Control Unit）から車載センサにより検出される情報を受信するようにしてもよい。 The sensor unit 14 includes, for example, a GPS (Global Positioning System) sensor, a gyro sensor, an acceleration sensor, and the like. The sensor unit 14 has a function as position detecting means for detecting position information, receives a GPS satellite signal by a GPS sensor, and measures position information (latitude and longitude) of the in-vehicle navigation device 10. Positioning by the sensor unit 14 is performed at a predetermined time interval (for example, every 3 seconds) as described above. Positioned position information is stored in the storage unit 12 as position information 121.
Note that the sensor unit 14 can further increase the positioning accuracy of the position information of the in-vehicle navigation device 10 based on the angular velocity measured by the gyro sensor or the acceleration sensor or the acceleration.
In addition, when the GPS communication is difficult or impossible, the sensor unit 14 uses AGPS (Assisted Global Positioning System) communication, and the position information of the in-vehicle navigation device 10 based on the base station information acquired from the communication unit 13. Can also be calculated.
In addition, the sensor part 14 is not restricted to the structure containing all the sensors mentioned above. For example, a part or all of the sensors described above may be included in an in-vehicle sensor (not shown) mounted on the vehicle 60a. In that case, the control unit 11 may receive a signal from the in-vehicle sensor, or may receive information detected by the in-vehicle sensor from an ECU (Electronic Control Unit) of the vehicle 60a.
　表示部１５は、液晶ディスプレイ、又は有機エレクトロルミネッセンスパネル等の表示デバイスにより構成される。表示部１５は、制御部１１からの指示を受けて画像を表示する。表示部１５が表示する情報としては、例えば、車載ナビゲーション装置１０の現在位置、位置情報１２１から読み出された車載ナビゲーション装置１０の現在位置周辺の地図情報、ユーザに設定された目的地、他の車載ナビゲーション装置１０から通知された待ち合わせ情報、ルート情報、各種のユーザインタフェース等が挙げられる。 The display unit 15 is configured by a display device such as a liquid crystal display or an organic electroluminescence panel. The display unit 15 displays an image in response to an instruction from the control unit 11. Examples of information displayed by the display unit 15 include the current position of the in-vehicle navigation device 10, map information around the current position of the in-vehicle navigation device 10 read from the position information 121, a destination set by the user, and other information. The waiting information notified from the vehicle-mounted navigation device 10, route information, various user interfaces, and the like can be mentioned.
　入力部１６は、テンキーと呼ばれる物理スイッチや表示部１５の表示面に重ねて設けられたタッチパネル等の入力装置（図示を省略する。）等で構成される。入力部１６からの操作入力、例えばユーザによるテンキーの押下、タッチパネルのタッチに基づいた信号を制御部１１に出力することで、ユーザによる選択操作や、地図の拡大縮小等の操作を実現することができる。 The input unit 16 includes a physical switch called a numeric keypad, an input device (not shown) such as a touch panel provided on the display surface of the display unit 15, and the like. By outputting a signal based on an operation input from the input unit 16, for example, a numeric keypad pressed by the user or a touch on the touch panel, to the control unit 11, a selection operation by the user, an operation such as map enlargement or reduction can be realized. it can.
　なお、この他、図示しないが、スピーカやマイク等を備えることもできる。スピーカは、運転者に対して音声出力を行い、マイクは、運転者によって発せられた音声等を集音する。
　そうすることで、情報をスピーカから音声で出力したり、マイクを介して音声入力された運転者による各種の選択、指示を音声認識技術により、制御部１１に入力したりすることもできる。 In addition, although not shown, a speaker, a microphone, or the like can be provided. The speaker outputs a sound to the driver, and the microphone collects a sound emitted by the driver.
By doing so, it is also possible to output information from a speaker by voice, or to input various selections and instructions by a driver who are voice-input via a microphone to the control unit 11 by voice recognition technology.
　次に、制御部１１の詳細について説明をする。制御部１１はＣＰＵ（Central Processing Unit）、ＲＡＭ（Random access memory）、ＲＯＭ（Read Only Memory）、及びＩ／Ｏ（Input / output）等を有するマイクロプロセッサにより構成される。ＣＰＵは、ＲＯＭ又は記憶部１２から読み出した各プログラムを実行し、その実行の際にはＲＡＭ、ＲＯＭ、及び記憶部１２から情報を読み出し、ＲＡＭ及び記憶部１２に対して情報の書き込みを行い、通信部１３、センサ部１４、表示部１５、及び入力部１６と信号の授受を行う。そして、このようにして、ハードウェアとソフトウェア（プログラム）が協働することにより本実施形態における処理は実現される。 Next, details of the control unit 11 will be described. The control unit 11 includes a microprocessor having a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), an I / O (Input Output / Output), and the like. The CPU executes each program read from the ROM or the storage unit 12, reads information from the RAM, ROM, and the storage unit 12 at the time of execution, and writes information to the RAM and the storage unit 12. It exchanges signals with the communication unit 13, the sensor unit 14, the display unit 15, and the input unit 16. In this way, the processing in this embodiment is realized by the cooperation of hardware and software (program).
　制御部１１は、機能ブロックとして、経路案内部１１１、位置情報送信部１１２、及び施設情報取得部１１３を備える。 The control unit 11 includes a route guide unit 111, a location information transmission unit 112, and a facility information acquisition unit 113 as functional blocks.
　経路案内部１１１は、ユーザによって入力又は選択された施設等の目的地までの経路案内処理を行う部分である。
　目的地までの経路案内処理は、一般的なカーナビゲーションシステムにおける経路案内処理と同等である。すなわち、経路案内部１１１は、記憶部１２に記憶されている地図情報（図示を省略する。）に基づいて目的地までの地図を生成し、この地図上にセンサ部１４により測位された車載ナビゲーション装置１０の現在位置と目的地の位置と目的地までのルート情報とを重ね、これを表示部１５に表示することにより経路案内を行うことができる。この場合に、さらに、図示を省略したスピーカから経路案内用の音声を出力するようにしてもよい。また、道路の混雑状況の情報や天気の情報等を通信部１３による通信により取得して、この取得した情報を経路案内処理に利用するようにしてもよい。
　なお、目的地までの経路案内処理については、当業者によく知られているので、これ以上の詳細な説明は省略する。 The route guidance unit 111 is a part that performs route guidance processing to a destination such as a facility input or selected by the user.
The route guidance process to the destination is equivalent to the route guidance process in a general car navigation system. That is, the route guidance unit 111 generates a map to the destination based on the map information (not shown) stored in the storage unit 12, and the vehicle-mounted navigation measured by the sensor unit 14 on this map. Route guidance can be performed by superimposing the current position of the device 10, the position of the destination, and the route information to the destination and displaying this on the display unit 15. In this case, route guidance sound may be output from a speaker (not shown). Alternatively, information on road congestion, weather information, and the like may be acquired through communication by the communication unit 13, and the acquired information may be used for route guidance processing.
Note that the route guidance processing to the destination is well known to those skilled in the art, and thus further detailed description is omitted.
　位置情報送信部１１２は、通信部１３を利用した無線通信により、記憶部１２に格納されている位置情報１２１及び識別情報１２２を、情報分析装置３０に対して送信する部分である。
　位置情報送信部１１２による、情報分析装置３０に対する位置情報１２１及び識別情報１２２の送信は、車両６０ａに乗車したユーザにより車両６０ａのイグニッションスイッチがオン（エンジンを始動）にされ、車載ナビゲーション装置１０が自動起動してから、車両６０ａのイグニッションスイッチがオフ（エンジンを停止）にされるまでの間、周期的に行われる。例えば、所定の時間間隔（例えば３秒間隔）でセンサ部１４が測位を行う都度、リアルタイムに送信が行われる。また、リアルタイムに情報分析装置３０に送信する替わりに、複数個まとめて（例えば３分間分の間に３秒間隔で更新された位置情報１２１と、識別情報１２２とをまとめて）、一度に送信するようにしてもよい。すなわち、いわゆるバースト送信をするようにしてもよい。かかる、所定の時間間隔の長さや、リアルタイムに送信するか、それともバースト送信するかは、本実施形態を適用する環境等に応じて、任意に設定することができる。
　このようにして、リアルタイム送信やバースト送信を行うことにより、位置情報送信部１１２は、センサ部１４が測位した車両６０ａの移動経路を特定するための位置情報１２１と、識別情報１２２とを、情報分析装置３０に対して送信する。 The position information transmission unit 112 is a part that transmits the position information 121 and the identification information 122 stored in the storage unit 12 to the information analysis device 30 by wireless communication using the communication unit 13.
The position information transmission unit 112 transmits the position information 121 and the identification information 122 to the information analysis device 30 by turning on the ignition switch of the vehicle 60a (starting the engine) by the user who gets on the vehicle 60a. This is periodically performed after the automatic activation until the ignition switch of the vehicle 60a is turned off (the engine is stopped). For example, transmission is performed in real time whenever the sensor unit 14 performs positioning at a predetermined time interval (for example, every 3 seconds). Further, instead of transmitting to the information analysis device 30 in real time, a plurality of them are collected together (for example, the positional information 121 updated at intervals of 3 seconds and the identification information 122 are collected together for 3 minutes) and transmitted at a time. You may make it do. That is, so-called burst transmission may be performed. The length of the predetermined time interval and whether to transmit in real time or burst transmission can be arbitrarily set according to the environment to which the present embodiment is applied.
In this way, by performing real-time transmission or burst transmission, the position information transmission unit 112 obtains position information 121 for identifying the moving route of the vehicle 60a measured by the sensor unit 14 and identification information 122 as information. It transmits with respect to the analyzer 30.
　この場合に、イグニッションスイッチがオン（エンジンを始動）にされ、車載ナビゲーション装置１０が自動起動した直後に測位された位置情報１２１により特定される位置を最初の車両位置、すなわち出発位置として情報分析装置３０に送信することができる。さらに、イグニッションスイッチがオフ（エンジン停止）される直前に測位された位置情報１２１により特定される位置を最終の車両位置、すなわち駐車位置として情報分析装置３０に送信することができる。
　この場合、出発位置を表す位置情報１２１であることや停車位置を表す位置情報１２１であることを示す情報（例えば、これらを示すフラグを１にする。）を、位置情報１２１に追加してから、情報分析装置３０に送信するようにしてもよい。なお、イグニッションスイッチがオフ（エンジン停止）される直前に測位された位置情報１２１（すなわち、停車位置）については、イグニッションスイッチがオン（エンジンを始動）にされ、車載ナビゲーション装置１０が再度起動した際に送信されてもよい。 In this case, the information switch is set with the position specified by the position information 121 measured immediately after the ignition switch is turned on (engine is started) and the in-vehicle navigation device 10 is automatically started as the first vehicle position, that is, the starting position. 30 can be transmitted. Furthermore, the position specified by the position information 121 measured immediately before the ignition switch is turned off (engine stop) can be transmitted to the information analysis apparatus 30 as the final vehicle position, that is, the parking position.
In this case, after adding the position information 121 indicating the departure position or the position information 121 indicating the stop position (for example, setting a flag indicating these to 1) to the position information 121. The information may be transmitted to the information analysis device 30. For the position information 121 (that is, the stop position) measured immediately before the ignition switch is turned off (engine stop), when the ignition switch is turned on (engine started) and the vehicle-mounted navigation device 10 is started again. May be sent to.
　また、バースト送信を行う場合であっても、経路案内部１１１により車両６０ａが施設等の目的地に到着したと判断された場合には、位置情報送信部１１２は、リアルタイムに送信を行うように切り換えるとよい。このようにすれば、施設等の目的地に到着後、施設等の目的地の位置情報１２１が送信される前に、イグニッションスイッチがオフ（エンジン停止）されてしまい、施設等の目的地の位置情報１２１が情報分析装置３０に対して送信されない、という事態を防止することができる。 Even when burst transmission is performed, if the route guidance unit 111 determines that the vehicle 60a has arrived at a destination such as a facility, the position information transmission unit 112 performs transmission in real time. It is good to switch. In this way, after arriving at the destination such as the facility, before the location information 121 of the destination such as the facility is transmitted, the ignition switch is turned off (engine stopped), and the location of the destination such as the facility is detected. A situation in which the information 121 is not transmitted to the information analysis apparatus 30 can be prevented.
　施設情報取得部１１３は、施設の施設情報を情報分析装置３０から受信して取得する。そして、施設情報取得部１１３は、情報分析装置３０から取得した施設情報を例えば表示部１５へ出力する等により、ユーザに提供することができる。
　具体的には、施設情報取得部１１３は、ユーザが車両６０ａを運転して移動するとき、情報分析装置３０により作成された当該ユーザのユーザプロファイル情報に基づいて、情報分析装置３０により当該ユーザの好みに合致すると推定された施設に関する施設情報を受信して取得することができる。
　なお、施設情報取得部１１３は、後述するように、ユーザが車両６０ａを運転して情報分析装置３０により当該ユーザの好みに合致すると推定された施設の近傍を移動するとき、当該施設に関する施設情報を受信して取得するようにしてもよい。 The facility information acquisition unit 113 receives and acquires facility information of the facility from the information analysis device 30. And the facility information acquisition part 113 can provide a user with the facility information acquired from the information analysis apparatus 30, for example by outputting to the display part 15.
Specifically, when the user moves by driving the vehicle 60a, the facility information acquisition unit 113 uses the information analysis device 30 to identify the user's user profile information created by the information analysis device 30. It is possible to receive and acquire facility information relating to facilities that are estimated to match the preferences.
As will be described later, the facility information acquisition unit 113 operates when the user drives the vehicle 60a and moves in the vicinity of the facility estimated by the information analysis device 30 to match the user's preference. May be received and acquired.
　なお、車両６０ａのユーザは、情報分析装置３０に対して施設情報を配信するか否かを明示的に要求するようにしてもよい。この場合、施設情報取得部１１３は、図３Ａに示すように、表示部１５に、例えば「施設情報配信開始ＯＮ」ボタンを表示するようにしてもよい。そうすることで、ユーザによる当該ボタンのタッチ操作により、施設情報配信開始をオンに操作された場合、施設情報取得部１１３は、通信部１３を介して、情報配信開始要求を、情報分析装置３０に送信するように構成することができる。
　そうすることで、施設情報取得部１１３は、情報分析装置３０から配信される施設情報を受信して取得することが可能となる。なお、施設情報配信開始のデフォルトをオンとすることで、施設情報取得部１１３は、情報分析装置３０から施設情報を受信して取得するようにしてもよい。 Note that the user of the vehicle 60 a may explicitly request whether or not to distribute facility information to the information analysis device 30. In this case, the facility information acquisition unit 113 may display, for example, a “facility information distribution start ON” button on the display unit 15 as illustrated in FIG. 3A. By doing so, when the facility information distribution start is turned on by a touch operation of the button by the user, the facility information acquisition unit 113 sends an information distribution start request to the information analysis device 30 via the communication unit 13. Can be configured to transmit to.
By doing so, the facility information acquisition unit 113 can receive and acquire the facility information distributed from the information analysis device 30. Note that the facility information acquisition unit 113 may receive and acquire facility information from the information analysis device 30 by turning on the default of facility information distribution start.
　施設情報取得部１１３は、情報分析装置３０から取得した施設情報に基づいて、例えば表示部１５に、図３Ｂに示すように、車両６０ａの現在位置周辺の地図上に配信された施設の位置を表示することができる。また、図３Ｃに示すように表示部１５に施設情報を表示させる。なお、図３Ｂ及び図３Ｃでは、施設が１個所あるケースを例示しているが、複数の施設に関する配信用情報が配信される場合、ユーザの画面切り換え操作等により、施設情報取得部１１３は、表示部１５にスクロール可能に施設情報を表示させることで、ユーザに対して立ち寄りたい施設を選択させるようにしてもよい。
　以上、車載ナビゲーション装置１０の構成について説明した。 Based on the facility information acquired from the information analysis device 30, the facility information acquisition unit 113 displays the location of the facility distributed on the map around the current position of the vehicle 60a on the display unit 15, for example, as shown in FIG. 3B. Can be displayed. Further, the facility information is displayed on the display unit 15 as shown in FIG. 3C. 3B and 3C exemplify a case where there is one facility, but when distribution information related to a plurality of facilities is distributed, the facility information acquisition unit 113 is operated by a user's screen switching operation or the like. By displaying the facility information in a scrollable manner on the display unit 15, the user may be allowed to select a facility that he / she wants to visit.
The configuration of the in-vehicle navigation device 10 has been described above.
　＜携帯端末２０が備える機能ブロック＞
　次に、携帯端末２０が備える機能ブロックについて図４のブロック図を参照して説明をする。
　ここで、上述した車載ナビゲーション装置１０は、車両６０ａから電源の供給を受けていたが、携帯端末２０は自身が備えるバッテリ（図示を省略する。）から電源の供給を受ける。ただし、バッテリを充電するために携帯端末２０が車両６０ｂのシガーソケット等から電源の供給を受けるようにしてもよい。 <Functional blocks provided in the mobile terminal 20>
Next, functional blocks provided in the mobile terminal 20 will be described with reference to the block diagram of FIG.
Here, the vehicle-mounted navigation device 10 described above receives power supply from the vehicle 60a, but the mobile terminal 20 receives power supply from a battery (not shown) included in the mobile terminal 20 itself. However, the portable terminal 20 may be supplied with power from a cigar socket or the like of the vehicle 60b in order to charge the battery.
　図４に示すように、携帯端末２０は、制御部２１と、記憶部２２と、通信部２３と、センサ部２４と、表示部２５と、入力部２６と、近距離通信部２７とを含んで構成される。
　ここで、制御部２１と、記憶部２２と、通信部２３と、表示部２５と、入力部２６は、上述した車載ナビゲーション装置１０が含む同名の機能ブロックと同等の機能を有している。つまり、上述した車載ナビゲーション装置１０の説明における「車載ナビゲーション装置１０」の文言を「携帯端末２０」を置き換えることにより、携帯端末２０の各機能ブロックの説明となるので、重複する再度の説明は省略する。なお、センサ部２４はセンサ部１４の含むセンサを全て含む構成に限られない。例えば、センサは一部又は全部が車両６０ｂの搭載する車載センサ（図示せず）に含まれるようにしてもよい。その場合、制御部２１は、車載センサからの信号を受信するようにしてもよいし、又は車両６０ｂのＥＣＵ（Electronic Control Unit）から車載センサにより検出される情報を受信するようにしてもよい。 As shown in FIG. 4, the mobile terminal 20 includes a control unit 21, a storage unit 22, a communication unit 23, a sensor unit 24, a display unit 25, an input unit 26, and a short-range communication unit 27. Consists of.
Here, the control part 21, the memory | storage part 22, the communication part 23, the display part 25, and the input part 26 have a function equivalent to the functional block of the same name which the vehicle-mounted navigation apparatus 10 mentioned above contains. That is, by replacing the term “in-vehicle navigation device 10” in the description of the in-vehicle navigation device 10 with “portable terminal 20”, the description of each functional block of the portable terminal 20 will be omitted. To do. The sensor unit 24 is not limited to the configuration including all the sensors included in the sensor unit 14. For example, some or all of the sensors may be included in an in-vehicle sensor (not shown) mounted on the vehicle 60b. In that case, the control unit 21 may receive a signal from the in-vehicle sensor, or may receive information detected by the in-vehicle sensor from an ECU (Electronic Control Unit) of the vehicle 60b.
　一方で、携帯端末２０は、近距離通信部２７を含んでいる点等で、車載ナビゲーション装置１０と相違するので、この相違点について、以下説明をする。
　近距離通信部２７は、ＮＦＣ（Near Field Communication）やＢｌｕｅｔｏｏｔｈ（登録商標）といった規格に準拠した非接触の近距離通信、又はＵＳＢ（Universal Serial Bus）ケーブル等を介した有線による近距離通信を行うための部分である。
　一方で、車両６０ｂは、近距離通信部２７と通信を行うための近距離通信部を備える。例えば車両６０ｂのＥＣＵ（Electronic Control Unit）が近距離通信部を備える。
　そして、携帯端末２０がＥＣＵと近距離通信により通信することができる場合とは、すなわち、携帯端末２０が車両６０ｂの車内に存在する場合である。この場合、携帯端末２０のセンサ部２４が測位する位置情報は、車両６０ｂの位置情報に相当することになる。 On the other hand, since the mobile terminal 20 is different from the vehicle-mounted navigation device 10 in that it includes the short-range communication unit 27, the difference will be described below.
The near field communication unit 27 performs non-contact near field communication based on standards such as NFC (Near Field Communication) and Bluetooth (registered trademark), or wired near field communication via a USB (Universal Serial Bus) cable or the like. It is a part for.
On the other hand, the vehicle 60 b includes a near field communication unit for communicating with the near field communication unit 27. For example, the ECU (Electronic Control Unit) of the vehicle 60b includes a short-range communication unit.
And the case where the portable terminal 20 can communicate with ECU by near field communication is a case where the portable terminal 20 exists in the vehicle 60b. In this case, the position information measured by the sensor unit 24 of the mobile terminal 20 corresponds to the position information of the vehicle 60b.
　そこで、携帯端末２０は、近距離通信部２７を介してＥＣＵと近距離通信できる間は、位置情報送信部２１２を起動させる。そして、起動した位置情報送信部２１２が、車載ナビゲーション装置１０の位置情報送信部１１２と同様にして、センサ部２４が測位した車両６０ｂの移動経路を特定するための位置情報２２１と、識別情報２２２とを、情報分析装置３０に対して送信する。 Therefore, the mobile terminal 20 activates the position information transmission unit 212 while it can perform near field communication with the ECU via the near field communication unit 27. Then, the activated position information transmission unit 212 is similar to the position information transmission unit 112 of the in-vehicle navigation device 10, and the position information 221 for identifying the movement route of the vehicle 60 b measured by the sensor unit 24 and the identification information 222. Is transmitted to the information analysis device 30.
　例えば、ユーザが携帯端末２０を所持して車両６０ｂに乗車し、イグニッションスイッチ等の車両６０ｂの起動スイッチをオンにすると、車両６０ｂと携帯端末２０とが接続（ペアリング）され、携帯端末２０で測位した位置情報２２１及び識別情報２２２が携帯端末２０から情報分析装置３０に送信される。この場合、車両６０ｂと携帯端末２０とのペアリング直後に測位された位置情報１２１により特定される位置を最初の車両位置、すなわち出発位置として情報分析装置３０に送信することができる。 For example, when the user has the mobile terminal 20 and gets on the vehicle 60b and turns on the start switch of the vehicle 60b such as an ignition switch, the vehicle 60b and the mobile terminal 20 are connected (paired), and the mobile terminal 20 Positioned position information 221 and identification information 222 are transmitted from the portable terminal 20 to the information analysis device 30. In this case, the position specified by the position information 121 measured immediately after the pairing of the vehicle 60b and the portable terminal 20 can be transmitted to the information analysis apparatus 30 as the first vehicle position, that is, the starting position.
　さらに、イグニッションスイッチ等の車両６０ｂの起動スイッチがオフにされると、車両６０ｂと携帯端末２０とのペアリングが解除される。この場合、解除された直前に測位された位置情報１２１により特定される位置を最終の車両位置、すなわち駐車位置として情報分析装置３０に送信することができる。
　この場合に、リアルタイムで送信してもよく、バースト送信してもよい点や、目的地に到着したと判断された場合には、バースト送信をリアルタイムの送信に切り換えてもよい点や、出発位置又は駐車位置であることを示す情報を追加してもよい点や、再起動時に駐車位置を送信してもよい点も位置情報送信部１１２と同様である。 Further, when the start switch of the vehicle 60b such as an ignition switch is turned off, the pairing between the vehicle 60b and the portable terminal 20 is released. In this case, the position specified by the position information 121 measured immediately before being released can be transmitted to the information analysis apparatus 30 as the final vehicle position, that is, the parking position.
In this case, transmission may be performed in real time, burst transmission may be performed, burst transmission may be switched to real time transmission when it is determined that the destination has been reached, or departure position Or the point which may add the information which shows that it is a parking position, and the point which may transmit a parking position at the time of restart are the same as that of the position information transmission part 112.
　なお、車両６０ｂが位置情報を測位する機能を有している場合には、センサ部２４が測位する位置情報ではなく、車両６０ｂが測位する位置情報を位置情報１２１として情報分析装置３０に送信するようにしてもよい。この場合、携帯端末２０から、センサ部２４を省略するようにしてもよい。 When the vehicle 60b has a function of positioning position information, the position information measured by the vehicle 60b is transmitted to the information analysis apparatus 30 as position information 121 instead of the position information measured by the sensor unit 24. You may do it. In this case, the sensor unit 24 may be omitted from the mobile terminal 20.
　＜情報分析装置３０が備える機能ブロック＞
　次に、情報分析装置３０が備える機能ブロックについて図５のブロック図を参照して説明をする。 <Functional Blocks Provided in Information Analysis Device 30>

Is done. In the figure, as information stored in the storage unit 32, map information 321, position information database 322, and facility information 323 relating to facilities, which are information relating to analysis processing of position information, are illustrated.
　地図情報３２１には、道路や施設等の地物に関する情報、道路情報、施設位置情報、駐車場情報等の情報が含まれる。また、地図情報３２１には他にも、道路及び道路地図等の背景を表示するための表示用地図データ、ノード（例えば道路の交差点、屈曲点、端点等）の位置情報及びその種別情報、各ノード間を結ぶ経路であるリンクの位置情報及びその種別情報、全てのリンクのコスト情報（例えば距離、所要時間等）に関するリンクコストデータ等を含む道路ネットワークデータ等が含まれる。
　道路情報としては道路の種別や信号機等のいわゆる道路地図の情報が保存されている。 The map information 321 includes information on features such as roads and facilities, information such as road information, facility position information, and parking lot information. The map information 321 also includes display map data for displaying backgrounds such as roads and road maps, position information of nodes (eg, road intersections, inflection points, end points, etc.) and their type information, Road network data including link cost data regarding link position information and its type information, which is a route connecting nodes, cost information (for example, distance, required time, etc.) of all links, and the like are included.
As road information, so-called road map information such as road types and traffic lights is stored.
　施設位置情報としては、各施設の位置情報が緯度経度の情報として保存されている。また、施設位置情報として、施設の識別情報（施設ＩＤ）、名称、施設のカテゴリー（施設の種別及び／又は施設のジャンル）等に関する施設情報が含まれていてもよい。
　駐車場情報としては、駐車場の位置情報が緯度経度の情報として保存されている。駐車場が各施設の駐車場である場合には、施設と駐車場を紐付けて保存される。 As facility location information, location information of each facility is stored as latitude and longitude information. The facility location information may include facility information related to facility identification information (facility ID), name, facility category (facility type and / or facility genre), and the like.
As the parking lot information, the location information of the parking lot is stored as latitude and longitude information. When the parking lot is a parking lot of each facility, the facility and the parking lot are linked and stored.
　地図情報３２１は、記憶部３２に予め記憶しておく構成としてもよいし、通信網５０に接続されたサーバ装置（図示を省略する。）等から必要に応じて適宜ダウンロードされる構成としてもよい。さらに、ユーザの入力等に応じて適宜修正されてもよい。 The map information 321 may be stored in advance in the storage unit 32, or may be downloaded as appropriate from a server device (not shown) connected to the communication network 50 as necessary. . Furthermore, it may be appropriately modified according to user input or the like.
　位置情報データベース３２２は、車載ナビゲーション装置１０及び携帯端末２０のそれぞれから受信した位置情報１２１及び位置情報２２１と識別情報１２２及び識別情報２２２とに基づいて構築されたデータベースである。位置情報データベース３２２は、後述の位置情報データベース作成部３１１により構築される。位置情報データベース３２２の詳細については、位置情報データベース作成部３１１の説明の際に後述する。なお、以下の説明では、位置情報１２１及び位置情報２２１を区別することなく説明する際は、符号を省略して「位置情報」と呼ぶ。また、同様に識別情報１２２及び識別情報２２２を区別することなく説明する際は、符号を省略して「識別情報」と呼ぶ。 The location information database 322 is a database constructed based on the location information 121, the location information 221, the identification information 122, and the identification information 222 received from the in-vehicle navigation device 10 and the mobile terminal 20, respectively. The position information database 322 is constructed by a position information database creation unit 311 described later. Details of the position information database 322 will be described later when the position information database creation unit 311 is described. In the following description, when the position information 121 and the position information 221 are described without being distinguished, the reference numerals are omitted and referred to as “position information”. Similarly, when the identification information 122 and the identification information 222 are described without being distinguished, the reference numerals are omitted and referred to as “identification information”.
　施設情報３２３は、基本情報として施設の識別情報（施設ＩＤ）、名称、施設のカテゴリー、を含むとともに、施設に関する配信用施設情報３２３１（図示せず）を含む。
　配信用施設情報３２３１は、例えば、基本情報に加えて、電話番号、住所、営業時間、施設が飲食店であれば提供するメニュー、施設が飲食店であれば提供するメニュー、商品役務等に関する施設情報、施設の広告情報等を含むようにしてもよい。また、配信用施設情報３２３１は施設の特典情報（例えば、商品若しくはサービスの値引き情報、クーポン情報、又はポイント情報等）を含むようにしてもよい。
　また、施設に関する配信用施設情報３２３１は、予め記憶しておく構成としてもよいし、通信網５０に接続された端末装置（図示省略）等から必要に応じて適宜作成更新される構成としてもよい。特に、配信用施設情報３２３１については、例えば施設に設置される端末装置（図示省略）等から当該施設の管理者の入力等に応じて適宜作成更新できるように構成してもよい。
　ここで、施設のカテゴリーについて説明する。本発明は、移動体ユーザが生活拠点位置から遠方に位置する施設への訪問から、当該施設の属する施設カテゴリーに対して嗜好度が高いと推定することで、移動体ユーザの施設カテゴリーに関連したユーザプロファイルを算出する。したがって、カテゴリーとしては、ユーザの嗜好度をより明確に示すことができるカテゴリーが好ましい。中華レストランを例にした場合、中華レストランを１つのカテゴリーとするよりも、例えば、中華（四川料理）、中華（飲茶）のように、ユーザの中華料理の嗜好度がより明確になるような施設カテゴリーが好ましい。そうすることで、ユーザプロファイルに関連付けられた施設カテゴリーに基づいて、より確度の高い情報配信が可能となる。なお、本発明では、施設カテゴリーについては、必要に応じて任意に設定される。 The facility information 323 includes facility identification information (facility ID), name, and facility category as basic information, and distribution facility information 3231 (not shown) regarding the facility.
The distribution facility information 3231 includes, for example, a telephone number, an address, business hours, a menu provided if the facility is a restaurant, a menu provided if the facility is a restaurant, a product service, etc. in addition to basic information Information, facility advertisement information, etc. may be included. Further, the distribution facility information 3231 may include facility privilege information (for example, discount information on products or services, coupon information, or point information).
Further, the distribution facility information 3231 related to the facility may be stored in advance, or may be appropriately created and updated as necessary from a terminal device (not shown) connected to the communication network 50 or the like. . In particular, the distribution facility information 3231 may be configured so as to be appropriately created and updated from a terminal device (not shown) installed in the facility, for example, according to the input of the manager of the facility.
Here, the facility category will be described. The present invention relates to the facility category of the mobile user by estimating that the mobile user has a high preference for the facility category to which the facility belongs from a visit to the facility located far from the living base location. User profile is calculated. Therefore, as the category, a category that can more clearly indicate the user's preference level is preferable. Taking a Chinese restaurant as an example, a facility where the user's preference for Chinese cuisine becomes clearer, such as Chinese (Sichuan cuisine) and Chinese (Dim Sum), rather than a Chinese restaurant as one category. Categories are preferred. By doing so, based on the facility category associated with the user profile, it is possible to distribute information with higher accuracy. In the present invention, the facility category is arbitrarily set as necessary.

Moreover, the communication part 33 is utilized in order to transmit facility information with respect to each of the vehicle-mounted navigation apparatus 10 and the portable terminal 20, for example.
However, data transmitted and received between the communication unit 33 and other devices is not particularly limited, and information other than these pieces of information may be transmitted and received.
　次に、制御部３１の詳細について説明をする。制御部３１はＣＰＵ（Central Processing Unit）、ＲＡＭ（Random access memory）、ＲＯＭ（Read Only Memory）、及びＩ／Ｏ（Input / output）等を有するマイクロプロセッサにより構成される。ＣＰＵは、ＲＯＭ又は記憶部３２から読み出した各プログラムを実行し、その実行の際にはＲＡＭ、ＲＯＭ、及び記憶部３２から情報を読み出し、ＲＡＭ及び記憶部３２に対して情報の書き込みを行い、通信部３３、センサ部３４、表示部３５、及び入力部３６と信号の授受を行う。そして、このようにして、ハードウェアとソフトウェア（プログラム）が協働することにより本実施形態における処理は実現される。

It exchanges signals with the communication unit 33, the sensor unit 34, the display unit 35, and the input unit 36. In this way, the processing in this embodiment is realized by the cooperation of hardware and software (program).

＜位置情報データベース作成部３１１＞
　位置情報データベース作成部３１１は、各車両６０から、当該車両６０の識別情報、位置情報、及び時刻情報等を通信部３３を介して受信する。さらに、位置情報データベース作成部３１１は、各車両６０から受信した識別情報、位置情報、及び時刻情報等に基づいて、位置情報データベース３２２を構築して、適宜作成更新する。位置情報データベース作成部３１１を説明する前に、先ず位置情報データベース３２２のデータ構造の一例について説明する。 <Position information database creation unit 311>
The position information database creation unit 311 receives identification information, position information, time information, and the like of the vehicle 60 from each vehicle 60 via the communication unit 33. Furthermore, the location information database creation unit 311 constructs the location information database 322 based on the identification information, location information, time information, and the like received from each vehicle 60, and appropriately creates and updates it. Before describing the position information database creation unit 311, an example of the data structure of the position information database 322 will be described first.
［位置情報データベース３２２について］
　図６に示すように、位置情報データベース３２２は、上述したようにして車載ナビゲーション装置１０及び携帯端末２０のそれぞれから受信した「位置情報」及び「識別情報」を含む。
　具体的には、車両６０がイグニッションオンされてから、イグニッションオフされるまで（すなわち、出発から到着まで）に定期的に送信される位置情報、時刻情報等を車両６０の識別情報毎に管理する移動履歴レコード（図示せず）に記憶される。こうすることで移動履歴レコードは、車両６０から逐次受信する現在位置の情報を記憶する。なお、受信は数秒に一度受信してもよいし、車両６０側で時系列的に保存しておき、一定時間、又は車両６０側でアプリを起動したとき等のタイミングでまとめて受信するようにしてもよい。なお、移動履歴レコードは、訪問施設が未定のレコードとして、位置情報データベース３２２の仮レコードとして記憶するようにしてもよい。
　なお、出発位置に対応する出発施設ＩＤ、及び到着位置に対応する訪問施設ＩＤについては、記憶部３２の地図情報３２１、施設位置情報等に基づいて、出発位置及び到着位置をそれぞれ、地図情報に含まれる施設情報と照らし合わせることにより、出発施設ＩＤ及び到着施設ＩＤを特定することができる。
　移動履歴レコードは、当該車両がイグニッションオフされると、到着位置である訪問施設が決定されることで、訪問施設情報を含む位置情報データベースのレコードとして記憶される。
　位置情報データベース３２２は、上述したようにして車載ナビゲーション装置１０及び携帯端末２０のそれぞれから受信した「位置情報」に基づいて位置情報データベース作成部３１１が特定した、「出発位置」、「訪問施設」を含む。前述したように、「訪問施設」は、車両６０が移動中の場合には未定データを含む。
　そして、位置情報データベース作成部３１１は、それぞれの属性に対応する情報を、フィールドに格納することにより、位置情報データベース３２２を構築及び更新する。 [About Location Information Database 322]
As shown in FIG. 6, the position information database 322 includes “position information” and “identification information” received from each of the in-vehicle navigation device 10 and the mobile terminal 20 as described above.
Specifically, position information, time information, and the like periodically transmitted from when the vehicle 60 is turned on until when the vehicle is turned off (that is, from departure to arrival) are managed for each identification information of the vehicle 60. It is stored in a movement history record (not shown). In this way, the movement history record stores information on the current position that is sequentially received from the vehicle 60. The reception may be received once every few seconds, stored in time series on the vehicle 60 side, and received together at a certain time or when the application is activated on the vehicle 60 side. May be. In addition, you may make it memorize | store a movement history record as a temporary record of the positional infomation database 322 as a record in which a visiting facility is undetermined.
For the departure facility ID corresponding to the departure position and the visit facility ID corresponding to the arrival position, the departure position and the arrival position are respectively converted into map information based on the map information 321 and the facility position information in the storage unit 32. The departure facility ID and the arrival facility ID can be specified by comparing with the included facility information.
When the vehicle is ignited off, the travel history record is stored as a record in the location information database including the visited facility information by determining the visited facility as the arrival position.
The location information database 322 is identified by the location information database creation unit 311 based on the “location information” received from each of the in-vehicle navigation device 10 and the mobile terminal 20 as described above. including. As described above, the “visiting facility” includes undetermined data when the vehicle 60 is moving.
Then, the location information database creation unit 311 constructs and updates the location information database 322 by storing information corresponding to each attribute in the field.
　ここで、位置情報データベース３２２内の「訪問施設」は、車両６０が移動中の場合を除いて、ユーザが車両６０により到着し滞在した場所（例えば施設、職場、学校等）を識別するための情報である。位置情報データベース作成部３１１は、車両６０がイグニッションオフされると、識別情報とともに受信した位置情報から、訪問施設を特定することができる。例えば、上述したように、位置情報に駐車位置を示す情報が含まれている場合を考える。この場合、この駐車位置と、地図情報３２１に含まれる各施設の位置（及び施設に紐付けられている駐車場の位置）を比較し、特定した駐車位置といずれかの施設の位置（及び施設に紐付けられている駐車場の位置）が一致した場合に、ユーザが、車両６０によりこの施設に到着し滞在したと判定する。
　そして、地図情報３２１に含まれる施設の識別情報（施設ＩＤ）が位置情報データベース３２２内の、訪問施設のフィールドに格納される。 Here, the “visit facility” in the location information database 322 is used for identifying a place (for example, a facility, a workplace, a school, etc.) where the user has arrived and stayed with the vehicle 60 except when the vehicle 60 is moving. Information. When the vehicle 60 is turned off, the location information database creation unit 311 can specify the visiting facility from the location information received together with the identification information. For example, as described above, consider a case where the position information includes information indicating the parking position. In this case, the parking position is compared with the position of each facility included in the map information 321 (and the position of the parking lot associated with the facility), and the specified parking position and the position of any facility (and the facility) If the locations of the parking lots associated with each other match, it is determined that the user has arrived at this facility by the vehicle 60 and stayed there.
Then, the facility identification information (facility ID) included in the map information 321 is stored in the visited facility field in the location information database 322.
　また、仮に位置情報に駐車位置を示す情報が含まれていない場合には、例えば、位置情報の送信が開始されて終了するまでの間の、最後に受信した位置情報に対応する位置や、一定時間変化しない位置を駐車位置であるとみなして、各施設の位置（及び施設に紐付けられている駐車場の位置）との比較をすることによって訪問施設を特定することもできる。
　さらに、仮に位置情報に駐車位置を示す情報が含まれていない場合には、例えば、経路案内において目的地として設定された施設を訪問施設として特定することもできる。 In addition, if the position information does not include information indicating the parking position, for example, the position corresponding to the position information received last until the transmission of the position information is terminated, It is also possible to identify a visiting facility by regarding a position that does not change over time as a parking position and comparing it with the position of each facility (and the position of the parking lot associated with the facility).
Further, if the position information does not include information indicating the parking position, for example, a facility set as a destination in route guidance can be specified as a visiting facility.
　なお、上述した駐車位置と、施設の位置の「一致」の度合いは任意に定めるようにしてよい。例えば、車載ナビゲーション装置１０や携帯端末２０が位置情報を精度良く測定できるような場合には、一致と判定する範囲を狭くするようにしてもよい。一方で、車載ナビゲーション装置１０や携帯端末２０が位置情報をそれほど精度良く測定できないような場合には、一致と判定する範囲を広くするようにしてもよい。つまり、多少位置がズレている場合にも一致と判定するようにしてもよい。 Note that the degree of “coincidence” between the parking position described above and the facility position may be arbitrarily determined. For example, when the in-vehicle navigation device 10 or the mobile terminal 20 can measure the position information with high accuracy, the range for determining coincidence may be narrowed. On the other hand, when the in-vehicle navigation device 10 and the portable terminal 20 cannot measure the position information with high accuracy, the range for determining the coincidence may be widened. In other words, it may be determined that there is a match even when the position is slightly shifted.
　また、位置情報データベース３２２内の「識別情報」は、上述したように位置情報の送信元である車載ナビゲーション装置１０や携帯端末２０を識別するための情報である。すなわち、車載ナビゲーション装置１０や携帯端末２０に対応する車両６０を識別する情報である。位置情報データベース作成部３１１は、位置情報とともに受信した識別情報をフィールドに格納する。 Further, the “identification information” in the position information database 322 is information for identifying the in-vehicle navigation device 10 or the portable terminal 20 that is the transmission source of the position information as described above. That is, the information identifies the vehicle 60 corresponding to the in-vehicle navigation device 10 or the mobile terminal 20. The position information database creation unit 311 stores the identification information received together with the position information in the field.
　また、位置情報データベース３２２内の「出発位置」は、訪問施設に移動した際の移動経路における出発位置である。
　位置情報データベース作成部３１１は、識別情報とともに受信した位置情報から、出発位置を特定する。例えば、上述したように、位置情報に出発位置を示す情報が含まれているならば、この情報により出発した位置を特定する。また、仮に位置情報に出発位置を示す情報が含まれていない場合には、例えば、位置情報の送信が開始されて終了するまでの間の、最初に受信した位置情報に対応する位置が出発位置であるとみなすこともできる。
　位置情報データベース作成部３１１は、このように特定した出発位置に基づいて、出発位置が地図情報３２１に含まれる施設（及び施設に紐付けられている駐車場）であるか否か、を特定することができる。
　また、後述するように、生活拠点推定部３１２は、位置情報データベース３２２に基づいて、例えば、過去に各日の最初に出発した位置が同じ位置である頻度が大きい場合、当該出発位置を当該ユーザの自宅位置と推定することができる。また、過去に各日（特に平日等）に自宅から移動して同じ停車位置で長時間滞在した後、当該停車位置を出発位置として、自宅に移動する頻度が大きい場合、当該停車位置を地図情報と照らし合わせることで、当該ユーザの職場又は学校等と推定することができる。 The “departure position” in the position information database 322 is a departure position on the movement route when moving to the visited facility.
The location information database creation unit 311 identifies the departure location from the location information received together with the identification information. For example, as described above, if the position information includes information indicating the starting position, the starting position is specified by this information. In addition, if the position information does not include information indicating the departure position, for example, the position corresponding to the first received position information from the start to the end of transmission of the position information is the departure position. Can also be considered.
The location information database creation unit 311 identifies whether the departure location is a facility (and a parking lot linked to the facility) included in the map information 321 based on the departure location identified in this way. be able to.
As will be described later, based on the position information database 322, the living base estimation unit 312 determines the departure position as the user when the first departure position of each day in the past is frequently the same position, for example. The home position can be estimated. In addition, if you travel from your home in the past on each day (especially on weekdays) and stay at the same stop for a long time and then use the stop as the departure position, and move frequently to your home, map the stop It can be estimated that the user's workplace or school or the like.
　また、位置情報データベース３２２内の「位置情報」は、訪問施設を訪問した際の移動経路における出発位置から駐車位置までの間の時間離散的に変化する位置情報の全てである。なお、位置情報データベース３２２内の「位置情報」には、最初の出発位置から当該訪問施設までの位置情報を連結して記憶させるものとする。位置情報データベース作成部３１１は、位置情報の送信が開始されて終了するまでの間に受信した全ての位置情報をフィールドに格納する。 Also, the “position information” in the position information database 322 is all position information that changes discretely in time from the departure position to the parking position on the travel route when visiting the visited facility. Note that the “location information” in the location information database 322 is linked to the location information from the first departure location to the visited facility. The position information database creation unit 311 stores all received position information in the field from the start to the end of transmission of position information.
　位置情報データベース作成部３１１は、いずれかの車載ナビゲーション装置１０及び携帯端末２０から位置情報及び識別情報の送信が一度開始されてから終了するまでの間、受信した位置情報及び識別情報に基づいて作成される移動履歴レコードに基づいて、位置情報データベース３２２を更新する。 The position information database creation unit 311 is created based on the received position information and identification information from the start to the end of transmission of the position information and identification information from any of the in-vehicle navigation device 10 and the mobile terminal 20. The position information database 322 is updated based on the movement history record to be performed.
＜生活拠点推定部３１２＞
　次に、生活拠点推定部３１２について説明をする。
　前述したように、生活拠点推定部３１２は、走行中の車両６０から受信した当該車両６０の識別情報に基づいて、位置情報データベース３２２の位置情報の過去の移動履歴を参照することで、当該車両６０の生活拠点位置（例えば自宅位置、職場、又は学校等の位置）を推定する。
　より具体的には、生活拠点推定部３１２は、位置情報データベース３２２に基づいて、例えば、過去に各日の最初に出発した位置が同じ位置である頻度が大きい場合、当該出発位置を当該ユーザの自宅位置と推定することができる。また、過去に各日（特に平日等）に自宅から移動して同じ停車位置に長時間滞在した後、当該停車位置を出発位置として、自宅に移動する頻度が大きい場合、当該停車位置を地図情報と照らし合わせることで、当該ユーザの職場又は学校等と推定することができる。
　なお、上述した同じ位置の「一致」の度合いは前述したように、任意に定めるようにしてよい。例えば、車載ナビゲーション装置１０や携帯端末２０が位置情報を精度良く測定できるような場合には、一致と判定する範囲を狭くするようにしてもよい。一方で、車載ナビゲーション装置１０や携帯端末２０が位置情報をそれほど精度良く測定できないような場合には、一致と判定する範囲を広くするようにしてもよい。つまり、多少位置がズレている場合にも停車位置を一致すると判定するようにしてもよい。
　また、車両６０の生活拠点位置の判定は、位置情報データベース作成部３１１が実行するようにしてもよい。 <Living base estimation unit 312>
Next, the living base estimation unit 312 will be described.
As described above, the living base estimation unit 312 refers to the past movement history of the position information in the position information database 322 based on the identification information of the vehicle 60 received from the traveling vehicle 60, so that the vehicle 60 living base positions (for example, positions such as a home position, a workplace, or a school) are estimated.
More specifically, based on the position information database 322, the living base estimation unit 312 determines the departure position of the user when the frequency at which the first departure position in the past is the same position is high, for example. It can be estimated as the home position. In addition, after moving from home on each day (especially on weekdays) in the past and staying at the same stop position for a long time, if the stop position is the departure position and the frequency of moving to the home is large, the stop position is displayed as map information It can be estimated that the user's workplace or school or the like.
The degree of “coincidence” at the same position as described above may be arbitrarily determined as described above. For example, when the in-vehicle navigation device 10 or the mobile terminal 20 can measure the position information with high accuracy, the range for determining coincidence may be narrowed. On the other hand, when the in-vehicle navigation device 10 and the portable terminal 20 cannot measure the position information with high accuracy, the range for determining the coincidence may be widened. That is, it may be determined that the stop positions coincide even when the positions are slightly shifted.
In addition, the position information database creation unit 311 may determine the living base position of the vehicle 60.
＜訪問施設データ作成部３１３＞
　訪問施設データ作成部３１３は、位置情報データベース３２２に基づいて、予め設定される所定期間内において、各車両６０が訪問した訪問施設の集合を判定することで、車両６０の識別情報と所定期間内に当該車両６０の訪問した施設のカテゴリー別の訪問施設の集合との対応関係を表す移動体訪問データを作成する。
　より具体的には、訪問施設データ作成部３１３は、各車両６０が所定期間内に訪問した訪問施設を施設のカテゴリー別に、訪問施設の施設ＩＤ、及び所定期間内に当該施設を訪問した訪問回数等を算出する。なお、訪問回数に加えて、各訪問毎に、訪問日時、滞在時間等を算出してもよい。
　そうすることで、訪問施設データ作成部３１３は、車両６０の識別番号に対して、当該車両６０が、所定期間内に訪問した訪問施設の施設ＩＤ、及び所定期間内に当該施設を訪問した訪問回数と、を対応付けた移動体訪問データを施設のカテゴリー別に作成することができる。なお、訪問施設データ作成部３１３は、当該訪問施設の訪問毎に、その訪問日時、滞在時間等の詳細データを加えるようにしてもよい。
　カテゴリー毎に、当該カテゴリーに属する施設への訪問回数を算出することで、当該車両６０のユーザの当該カテゴリーに属する施設に対する嗜好度が、より高いと判定することができる。移動体ユーザの施設に対する好みをさらに正確に推定することができる。また、各訪問の訪問日時、及び滞在時間等を分析することで、当該移動体ユーザの当該カテゴリーに属する施設を訪問する時間帯の傾向を把握することができる。 <Visit facility data creation unit 313>
The visiting facility data creation unit 313 determines the set of visiting facilities visited by each vehicle 60 within a predetermined period based on the position information database 322, thereby identifying the identification information of the vehicle 60 and the predetermined period. The mobile visit data representing the correspondence with the set of visiting facilities by category of the facility visited by the vehicle 60 is created.
More specifically, the visit facility data creation unit 313 visits the visit facilities visited by each vehicle 60 within a predetermined period for each facility category, the visit facility ID of the visit facility, and the number of visits that visited the facility within the predetermined period. Etc. are calculated. In addition to the number of visits, the visit date and time, stay time, etc. may be calculated for each visit.
By doing so, the visiting facility data creation unit 313 corresponds to the identification number of the vehicle 60, the facility ID of the visiting facility visited by the vehicle 60 within the predetermined period, and the visit that visited the facility within the predetermined period. Mobile visit data in which the number of times is associated can be created for each category of facility. The visit facility data creation unit 313 may add detailed data such as the visit date and time and the stay time for each visit of the visit facility.
By calculating the number of visits to facilities belonging to the category for each category, it can be determined that the user's preference of the vehicle 60 for the facility belonging to the category is higher. It is possible to more accurately estimate the preference of the mobile user for the facility. Further, by analyzing the visit date and time of each visit, the stay time, etc., it is possible to grasp the tendency of the time zone for visiting the facility belonging to the category of the mobile user.
＜ユーザプロファイル設定部３１４＞
　ユーザプロファイル設定部３１４は、移動体ユーザ毎に、訪問施設データ作成部３１３により作成された施設のカテゴリー別に作成された移動体訪問データに基づいて、訪問施設の位置が当該車両６０の当該移動体ユーザの何れの生活拠点位置からも遠方に位置する訪問施設に係る移動体訪問データの部分集合を作成する。
　より具体的には、ユーザプロファイル設定部３１４は、移動体ユーザ毎に、施設のカテゴリー別に、訪問施設の位置が当該車両６０のユーザの何れの生活拠点位置からも予め設定された第１所定範囲外に位置する訪問施設の施設ＩＤ、施設名称、所定期間内に当該施設を訪問した訪問回数等を対応付けた移動体訪問データからなる部分集合リストを作成する。すなわち、移動体ユーザ毎に、施設カテゴリー別に、当該移動体ユーザの生活拠点位置から第１所定範囲外に位置する訪問施設に係る訪問回数等のリスト（「移動体訪問データ」ともいう）を作成する。
　ここで、第１所定範囲は任意の大きさとすることができる。例えば、当該車両６０のユーザの生活拠点位置を中心とした半径Ｎ１［ｋｍ］（Ｎ１は、任意の正の値）の範囲を第１所定範囲とすることができる。また、半径ではなく、例えば当該車両６０のユーザの生活拠点位置から当該施設までの道路上での移動距離がＮ１［ｋｍ］の範囲を第１所定範囲とするようにしてもよい。また、他にも例えば当該車両６０のユーザの生活拠点位置から訪問施設位置までの所要移動時間に基づいて第１所定範囲を決定するようにしてもよい。第１所定範囲の大きさは適宜設定することができる。
　このように、ユーザプロファイル設定部３１４は、移動体ユーザ毎に、所定期間内において、当該移動体ユーザの訪問した、当該移動体ユーザの生活拠点位置から遠方に位置する施設に係る移動体訪問データを施設カテゴリー別に記憶した（施設カテゴリーに属する施設への訪問回数を加味した）ユーザプロファイルを設定することができる。
　そうすることで、施設カテゴリーに関連したユーザプロファイルを参照することで、施設のカテゴリー毎に、当該移動体ユーザの嗜好度を判定することが可能となる。
　例えば、移動体ユーザが、自身の生活拠点から遠い距離の施設に数多く訪問している場合、当該施設の属する施設カテゴリーに対する嗜好度がより高いと判定することができ、移動体ユーザの好みをさらに正確に推定することができる。 <User profile setting unit 314>
For each mobile user, the user profile setting unit 314 determines that the location of the visit facility is the mobile body of the vehicle 60 based on the mobile body visit data created for each facility category created by the visit facility data creation unit 313. A subset of mobile visit data relating to a visit facility located far from any living base position of the user is created.
More specifically, the user profile setting unit 314 has a first predetermined range in which, for each mobile user, the location of the visiting facility is set in advance from any living location of the user of the vehicle 60 for each category of facility. A subset list composed of mobile visit data that associates the facility ID of the visiting facility located outside, the facility name, the number of visits that visited the facility within a predetermined period, and the like is created. That is, for each facility user, a list of visit counts related to visiting facilities located outside the first predetermined range from the location of the user's living base (also referred to as “mobile object visit data”) is created for each facility category. To do.
Here, the first predetermined range can be an arbitrary size. For example, a range of radius N 1 [km] (N 1 is an arbitrary positive value) centered on the life base position of the user of the vehicle 60 can be set as the first predetermined range. Further, instead of the radius, for example, a range in which the travel distance on the road from the user's living base position of the vehicle 60 to the facility is N 1 [km] may be set as the first predetermined range. In addition, for example, the first predetermined range may be determined based on the required travel time from the living base position of the user of the vehicle 60 to the visiting facility position. The size of the first predetermined range can be set as appropriate.
In this way, the user profile setting unit 314, for each mobile user, visits the mobile body visit data related to a facility located far from the living base position of the mobile user visited by the mobile user within a predetermined period. Can be set for each facility category (in consideration of the number of visits to facilities belonging to the facility category).
By doing so, it is possible to determine the preference level of the mobile user for each facility category by referring to the user profile related to the facility category.
For example, when a mobile user visits many facilities far from his / her living base, it can be determined that the preference for the facility category to which the facility belongs is higher, and the mobile user's preference is further increased It can be estimated accurately.
＜施設情報配信部３１５＞
　施設情報配信部３１５は、移動体ユーザ毎に、ユーザプロファイル設定部３１４により設定された、施設カテゴリーに関連したユーザプロファイルに基づいて、当該移動体ユーザの嗜好度が高いと推定される施設カテゴリーに属する施設の情報を当該移動体ユーザに対して配信する。この場合、施設カテゴリーに関連したユーザプロファイルに基づいて、当該移動体ユーザの訪問回数の多い施設カテゴリーに属する、任意の施設の配信用施設情報を優先的に配信するようにしてもよい。
　こうすることで、当該移動体ユーザが当該施設を訪問する確度をさらに高めることができる。
　また、施設情報配信部３１５は、移動体ユーザ毎に、ユーザプロファイル設定部３１４により設定された施設カテゴリーに関連したユーザプロファイルに基づいて、嗜好度が高いと推定される施設であっても、例えば、移動体ユーザが、当該施設カテゴリーについては、遠方に位置する施設を頻繁に訪問する場合には、当該移動体ユーザは、自身の生活拠点位置から近くに位置する当該施設カテゴリーに属する施設はあまり好みではない可能性が高いことから、配信用施設情報を生活拠点から第２所定範囲外に位置する施設に限定することで、当該移動体ユーザが当該施設を訪問する確度をより高めることができる。ここで、第２所定範囲は、第１所定範囲と同じであってもよいし、また、任意に設定してもよい。 <Facility information distribution unit 315>
The facility information distribution unit 315 sets, for each mobile user, a facility category that is estimated to have high preference for the mobile user based on the user profile set by the user profile setting unit 314 and related to the facility category. Information on the facility to which the user belongs is distributed to the mobile user. In this case, based on the user profile related to the facility category, the facility information for distribution of any facility belonging to the facility category where the mobile user visits frequently may be preferentially distributed.
By doing so, the probability that the mobile user visits the facility can be further increased.
Moreover, even if the facility information distribution unit 315 is a facility that is estimated to have a high preference level based on the user profile related to the facility category set by the user profile setting unit 314 for each mobile user, for example, When a mobile user frequently visits a facility located far away for the facility category, the mobile user is not likely to belong to the facility category that is located near his / her living location. Since there is a high possibility that it is not a preference, by limiting the facility information for distribution to facilities located outside the second predetermined range from the living base, it is possible to further increase the probability that the mobile user will visit the facility. . Here, the second predetermined range may be the same as the first predetermined range, or may be set arbitrarily.
　以上、本発明の情報分析システム１の各機能部の実施形態を、車両６０に搭載される車載ナビゲーション装置１０、携帯端末２０、及び情報分析装置３０の構成に基づいて説明した。なお、本発明の情報分析装置３０の備える各機能部の実施形態は、１台のコンピュータでも、１箇所にある又は数箇所に分散され、通信ネットワークによって相互接続された多数のコンピュータでも分散して実行するように展開できる。また、クラウド上の複数の仮想コンピュータを用いて構成することもできる。 As described above, the embodiments of the functional units of the information analysis system 1 of the present invention have been described based on the configurations of the in-vehicle navigation device 10, the mobile terminal 20, and the information analysis device 30 mounted on the vehicle 60. In addition, the embodiment of each functional unit included in the information analysis apparatus 30 according to the present invention may be distributed in a single computer or a large number of computers in one place or distributed in several places and interconnected by a communication network. Can be deployed to run. It can also be configured using a plurality of virtual computers on the cloud.
　＜本実施形態の動作＞
　次に、図７及び図８のフローチャートを参照して、本実施形態の動作について説明する。ここで、図７は、位置情報の収集及び位置情報データベースの更新時の動作を示すフローチャートである。また、図８は、移動体ユーザ（車両６０のユーザ）に関するユーザプロファイル作成時の動作を示すフローチャートである。 <Operation of this embodiment>
Next, the operation of this embodiment will be described with reference to the flowcharts of FIGS. Here, FIG. 7 is a flowchart showing operations at the time of collecting position information and updating the position information database. Moreover, FIG. 8 is a flowchart which shows the operation | movement at the time of user profile preparation regarding a mobile user (user of the vehicle 60).
　まず、車載ナビゲーション装置１０についての位置情報の収集及び位置情報データベース３２２の作成更新時の動作について図７を参照して説明する。
　位置情報送信部１１２が位置情報の送信を開始するか否かを判定する（ステップＳ１１）。ここで、上述したように、車両６０ａのイグニッションスイッチがオンとなった場合に送信が開始される。イグニッションスイッチがオフのままの場合には（ステップＳ１１にてＮｏ）、位置情報送信部１１２による送信は開始されない。一方で、イグニッションスイッチがオンとなった場合には（ステップＳ１１にてＹｅｓ）、ステップＳ１２に進む。 First, the operation at the time of collecting position information and creating and updating the position information database 322 for the in-vehicle navigation device 10 will be described with reference to FIG.
The position information transmission unit 112 determines whether or not to start transmission of position information (step S11). Here, as described above, transmission is started when the ignition switch of the vehicle 60a is turned on. If the ignition switch remains off (No in step S11), transmission by position information transmission unit 112 is not started. On the other hand, when the ignition switch is turned on (Yes in step S11), the process proceeds to step S12.
　ステップＳ１２では、センサ部１４が、車載ナビゲーション装置１０の位置を測位することにより位置情報を取得する（ステップＳ１２）。
　位置情報送信部１１２は、センサ部１４から位置情報を取得し、取得した位置情報を情報分析装置３０に対して、所定の周期で、リアルタイム送信又はバースト送信をする（ステップＳ１３）。 In step S12, the sensor unit 14 acquires position information by measuring the position of the in-vehicle navigation device 10 (step S12).
The position information transmission unit 112 acquires position information from the sensor unit 14, and performs real-time transmission or burst transmission of the acquired position information to the information analysis apparatus 30 at a predetermined cycle (step S13).
　ステップＳ１４では、情報分析装置３０の位置情報データベース作成部３１１が、ステップＳ１３により送信された位置情報に基づいて位置情報データベース３２２における移動履歴レコードを作成更新する。 In step S14, the location information database creation unit 311 of the information analysis device 30 creates and updates a movement history record in the location information database 322 based on the location information transmitted in step S13.
　次に、位置情報送信部１１２が位置情報の送信を終了するか否かを判定する（ステップＳ１５）。上述したように、車両６０ａのイグニッションスイッチがオフとなった場合に送信が終了となる。車両６０ａのイグニッションスイッチがオンのままの場合には（ステップＳ１５にてＮｏ）、ステップＳ１２における測位、ステップＳ１３における送信、及びステップＳ１４における位置情報データベース３２２における移動履歴レコードの作成更新が繰り返される。 Next, the position information transmission unit 112 determines whether or not to end the transmission of the position information (step S15). As described above, transmission ends when the ignition switch of the vehicle 60a is turned off. If the ignition switch of vehicle 60a remains on (No in step S15), the positioning in step S12, the transmission in step S13, and the creation and update of the movement history record in position information database 322 in step S14 are repeated.
　一方で、車両６０ａのイグニッションスイッチがオフとなった場合には（ステップＳ１５にてＹｅｓ）、ステップＳ１６に移る。 On the other hand, when the ignition switch of the vehicle 60a is turned off (Yes in step S15), the process proceeds to step S16.
　ステップＳ１６では、情報分析装置３０の位置情報データベース作成部３１１が、位置情報の送信終了により当該移動履歴レコードの訪問施設を決定することで、位置情報データベース３２２（訪問施設）を更新する。
　以上説明した動作により、位置情報の収集及び位置情報データベースの作成更新が実現される。 In step S <b> 16, the location information database creation unit 311 of the information analysis device 30 updates the location information database 322 (visit facility) by determining the visited facility of the movement history record when transmission of the location information ends.
By the operation described above, collection of position information and creation / update of the position information database are realized.
　次に、携帯端末２０についての位置情報の収集及び位置情報データベースの更新時の動作について説明する。携帯端末２０については、上述の説明における、位置情報送信部１１２を位置情報送信部２１２に置き換え、センサ部１４をセンサ部２４に置き換え、ステップＳ１１にてＹｅｓとなる基準を「イグニッションスイッチ等の車両６０ｂの起動スイッチがオンとなり、車両６０ｂと携帯端末２０がペアリングした場合」に置き換え、ステップＳ１４にてＹｅｓとなる基準を「イグニッションスイッチ等の車両６０ｂの起動スイッチがオフとなり、車両６０ｂと携帯端末２０のペアリングが解除された場合」に置き換えればよい。従って重複する説明を省略する。 Next, operations for collecting location information and updating the location information database for the mobile terminal 20 will be described. As for the portable terminal 20, in the above description, the position information transmission unit 112 is replaced with the position information transmission unit 212, the sensor unit 14 is replaced with the sensor unit 24, and the criterion of Yes in step S11 is “vehicles such as an ignition switch”. 60b is turned on and the vehicle 60b and the portable terminal 20 are paired ", and the criterion of Yes in step S14 is" the start switch of the vehicle 60b such as an ignition switch is turned off and the vehicle 60b and the portable terminal 20 are carried. " It may be replaced with “when pairing of terminal 20 is released”. Therefore, the overlapping description is omitted.
　次に、図８のフローチャートを参照して、情報分析装置３０による、移動体ユーザ（車両６０のユーザ）に関するユーザプロファイル作成時の動作について説明をする。
　ステップＳ２１において、制御部３１は、位置情報データベース３２２から、予め設定された所定期間内の車両６０の移動履歴レコードを車両６０の識別情報に基づいて抽出する。ここで、所定期間は、予め入力されているものとする。 Next, with reference to the flowchart of FIG. 8, the operation | movement at the time of the user profile preparation regarding a mobile user (user of the vehicle 60) by the information analysis apparatus 30 is demonstrated.
In step S <b> 21, the control unit 31 extracts a movement history record of the vehicle 60 within a predetermined period set in advance from the position information database 322 based on the identification information of the vehicle 60. Here, it is assumed that the predetermined period is input in advance.
　ステップＳ２２において、生活拠点推定部３１２は、当該車両６０の移動履歴に基づいてユーザの生活拠点位置を推定する。 In step S <b> 22, the living base estimation unit 312 estimates the user's living base position based on the movement history of the vehicle 60.
　ステップＳ２３において、訪問施設データ作成部３１３は当該車両６０の訪問した訪問施設ｉ毎に、当該訪問施設ｉを到着位置とする移動履歴レコードの部分集合Ｓｉ（１≦ｉ≦ｎ）を抽出する。ここで、車両６０の訪問した異なる施設数をｎとした場合、ｉは１≦ｉ≦ｎを満たす自然数で、各訪問施設を識別するインデックスとする。例えば、訪問施設データ作成部３１３は、移動履歴レコードを訪問施設ＩＤに基づいて、ソートすることで、訪問施設ｉ毎に、訪問施設ｉを到着位置とする移動レコードの部分集合Ｓｉ（１≦ｉ≦ｎ）を抽出することができる。 In step S23, the visited facility data creation unit 313 extracts, for each visited facility i visited by the vehicle 60, a subset Si (1 ≦ i ≦ n) of the movement history record having the visited facility i as an arrival position. Here, when the number of different facilities visited by the vehicle 60 is n, i is a natural number satisfying 1 ≦ i ≦ n and is an index for identifying each visited facility. For example, the visiting facility data creation unit 313 sorts the movement history records based on the visiting facility IDs, so that for each visiting facility i, a subset Si (1 ≦ i) of moving records having the visiting facility i as the arrival position. ≦ n) can be extracted.
　ステップＳ２４において、訪問施設データ作成部３１３は、部分集合Ｓｉに基づいて、車両６０の訪問施設ｉへの訪問回数Ｎｉ＝ｎ（Ｓｉ）を算出するとともに、施設情報３２３と照らし合わせることにより、訪問施設ｉのカテゴリーＣ（ｉ）を算出する。 In step S24, the visit facility data creation unit 313 calculates the number of visits Ni = n (Si) of the vehicle 60 to the visit facility i based on the subset Si, and compares the visit information with the facility information 323. The category C (i) of the facility i is calculated.
　ステップＳ２５において、訪問施設データ作成部３１３は、車両６０が所定期間内に訪問した訪問施設ｉの施設ＩＤ、所定期間内に当該施設を訪問した訪問回数Ｎｉと、を対応付けた移動体訪問データＰｉを施設ｉのカテゴリー別にまとめる。すなわち、施設ｉの属するカテゴリーと施設ｊ(ｊ≠ｉ)の属するカテゴリーが同じ場合、施設ｉに係る移動体訪問データＰｉと施設ｊに係る移動体訪問データＰｊとは、同じカテゴリーに関連した施設としてまとめられる。 In step S25, the visiting facility data creation unit 313 associates the facility ID of the visiting facility i visited by the vehicle 60 within a predetermined period with the number of visits Ni that visited the facility within the predetermined period. Organize Pi by category of facility i. That is, when the category to which the facility i belongs and the category to which the facility j (j ≠ i) belong are the same, the mobile visit data Pi related to the facility i and the mobile visit data Pj related to the facility j are related to the same category. Can be summarized as:
　次に、ステップＳ２６において、ユーザプロファイル設定部３１４は、ステップＳ２５において作成された各カテゴリー別に、当該カテゴリーに含まれる各移動体訪問データＰｉ（１≦ｉ≦ｎ）に対応する施設ｉの位置が車両６０のユーザの何れの生活拠点位置からも第１所定範囲外に位置する移動体訪問データＰｉからなる部分集合｛Ｐｉ｝を、施設のカテゴリーに関連する当該車両６０のユーザのユーザプロファイルとする。なお、施設のカテゴリーに関連したユーザプロファイル情報として、例えば、当該カテゴリーに含まれる各移動体訪問データＰｉの訪問回数の合計値を当該カテゴリーに対する嗜好度としてもよい。また、生活拠点位置からの距離に係る重み付けをした各施設への訪問回数の合計値を当該カテゴリーに対する嗜好度としてもよい。施設のカテゴリーに関連したユーザプロファイル情報は、前述した移動体訪問データＰｉからなる部分集合｛Ｐｉ｝に基づいて任意に設定することができる。 Next, in step S26, the user profile setting unit 314 determines, for each category created in step S25, the position of the facility i corresponding to each mobile visit data Pi (1 ≦ i ≦ n) included in the category. A subset {Pi} consisting of mobile visit data Pi located outside the first predetermined range from any living base position of the user of the vehicle 60 is set as a user profile of the user of the vehicle 60 related to the facility category. . As the user profile information related to the facility category, for example, the total number of visits of each mobile visit data Pi included in the category may be set as the preference level for the category. Moreover, it is good also considering the total value of the frequency | count of visit to each facility weighted according to the distance from a living base position as a preference degree with respect to the said category. The user profile information related to the facility category can be arbitrarily set based on the subset {Pi} composed of the mobile visit data Pi described above.
　以上により、車両６０のユーザのユーザプロファイルを作成することができる。
　そして、全ての移動体ユーザ毎に、ステップＳ２１からステップＳ２６を繰り返し実行することで、全移動体ユーザのユーザプロファイルを作成することができる。 As described above, the user profile of the user of the vehicle 60 can be created.
Then, the user profiles of all mobile users can be created by repeatedly executing Step S21 to Step S26 for every mobile user.
　以上説明した、本実施形態によれば、移動体が訪問した施設について当該移動体ユーザの生活拠点からの距離に基づいて当該移動体ユーザの嗜好を推定し、当該移動体ユーザのプロファイル情報を作成・更新することで、位置情報を用いてユーザの好みをより正確に推定することが可能となる。 According to the present embodiment described above, the mobile user's preference is estimated based on the distance from the mobile user's life base for the facility visited by the mobile body, and the mobile user's profile information is created. -By updating, it becomes possible to estimate a user's preference more accurately using position information.

In this case, the information analysis device 30 may further include a route guidance function, and the information analysis device 30 may perform route guidance by communicating with the in-vehicle navigation device 10 and the mobile terminal 20.
　さらに、他の変形例として、上述の実施形態では、情報分析装置３０を１つのサーバ装置等により実現すると説明したが、情報分析装置３０の各機能を、適宜複数のサーバ装置に分散する、分散処理システムとしてもよい。また、クラウド上で仮想サーバ機能等を利用して、情報分析装置３０の各機能を実現してもよい。 Furthermore, as another modification, in the above-described embodiment, it has been described that the information analysis device 30 is realized by one server device or the like.
