　この発明は、搭乗員の生体情報や趣向に応じた目的地候補の提示及び経路の変更を行うナビゲーション装置に関するものである。 This invention relates to a navigation device that presents destination candidates and changes routes according to the biological information and preferences of the crew members.
　特許文献１に記載のナビゲーション装置では、乗員構成等の車内状況に応じてユーザが必要とする目的地情報を簡単かつ迅速に検索するナビゲーションを行うために、乗車人数あるいは乗員の嗜好等の車内状況に基づいて目的地の検索条件を生成する。これにより、ユーザが所望する目的地が見つかるまでの検索操作の負荷軽減や検索時間の短縮化を可能としている。 In the navigation device described in Patent Document 1, in order to perform navigation for easily and quickly searching for destination information required by the user according to the in-vehicle situation such as the occupant configuration, the in-vehicle state such as the number of passengers or passenger preference Based on the above, a search condition for the destination is generated. As a result, it is possible to reduce the load of the search operation and shorten the search time until the destination desired by the user is found.
　しかしながら、特許文献１では、目的地絞り込みの検索条件を生成する際に車内状況を用いるので、目的地の検索開始等のユーザ操作が依然として残る。このため、乗員が運転者のみであった場合、運転中は目的地の検索開始操作を行うことができず、ユーザが所望するタイミングで目的地を検索できないという課題があった。 However, in Patent Document 1, since the in-vehicle situation is used when generating the search condition for narrowing down the destination, user operations such as starting the search for the destination remain. For this reason, when the occupant is only the driver, there is a problem that the destination search start operation cannot be performed during driving, and the destination cannot be searched at a timing desired by the user.
　また、特許文献１に記載されるユーザの嗜好は喫煙に関するもののみであり、例えば、運転者や同乗者の飲食に関する嗜好は考慮されておらず、ユーザが所望する目的地を精度よく提示できない。 In addition, the user's preference described in Patent Document 1 is only related to smoking. For example, the preference regarding the eating and drinking of the driver and passengers is not considered, and the destination desired by the user cannot be accurately presented.
　この発明は、上記のような課題を解決するためになされたもので、車両の搭乗員の生体情報や趣向から、ユーザの現状に即した適切なタイミングで、ユーザが所望する目的地候補及び経路の提示を行うことができるナビゲーション装置を得ることを目的とする。 The present invention has been made in order to solve the above-described problems. The destination candidate and the route desired by the user at an appropriate timing according to the current state of the user based on the biological information and preferences of the crew of the vehicle. An object of the present invention is to obtain a navigation device capable of presenting.

The in-vehicle network 90 is a single wireless or wired communication line that connects to the navigation device 10, the various sensors 20, and the storage devices stored in the database 30.
　図２は、実施の形態１によるナビゲーション装置の構成を示すブロック図である。図２において、ナビゲーション装置１０は、趣向情報取得部１１、生体情報記憶部１２、ユーザ状態判定部１３、ユーザ状態記憶部１３ａ、目的地情報取得部１４、時間情報取得部１５、時間情報記憶部１５ａ、現在地情報取得部１６、装置制御部１７、表示装置制御部１８及び表示装置部１９を備える。 FIG. 2 is a block diagram showing a configuration of the navigation device according to the first embodiment. In FIG. 2, the navigation apparatus 10 includes a preference information acquisition unit 11, a biological information storage unit 12, a user state determination unit 13, a user state storage unit 13a, a destination information acquisition unit 14, a time information acquisition unit 15, and a time information storage unit. 15a, the present location information acquisition part 16, the apparatus control part 17, the display apparatus control part 18, and the display apparatus part 19 are provided.
　趣向情報取得部１１は、ユーザ趣向情報１００を取得する構成部である。例えば、表示装置部１９に入力用画面を表示し、この入力用画面を基にユーザ趣向情報１００が入力される、ユーザ趣向情報１００の入力用のＨＭＩ（Human Machine Interface）である。ユーザ趣向情報１００を入力する構成には、キー操作部や音声入力装置などのナビゲーション装置１０に実装された入力装置が利用できる。 The preference information acquisition unit 11 is a component that acquires the user preference information 100. For example, it is an HMI (Human Machine Interface) for inputting user preference information 100 in which an input screen is displayed on the display unit 19 and user preference information 100 is input based on this input screen. For the configuration for inputting the user preference information 100, an input device mounted on the navigation device 10 such as a key operation unit or a voice input device can be used.
　生体情報記憶部１２は、各種センサ２０で検出された生体情報１０１を記憶する記憶部である。生体情報記憶部１２では、各種センサ２０にて生体情報１０１が検出されると、検出された生体情報１０１が車内ネットワーク９０を介して取得し記憶される。また、生体情報記憶部１２に記憶された生体情報１０１は、ユーザ状態判定部１３によって所定の周期で読み出される。ユーザ状態判定部１３は、ユーザ趣向情報１００及び生体情報１０１に基づいてユーザの空腹度や疲労度などのユーザ状態情報１０２を判定する構成部である。ユーザ状態情報１０２の判定方法については後述する。ユーザ状態記憶部１３ａは、ユーザ状態判定部１３で得られたユーザ状態情報１０２を記憶する記憶部である。 The biological information storage unit 12 is a storage unit that stores the biological information 101 detected by the various sensors 20. In the biological information storage unit 12, when the biological information 101 is detected by the various sensors 20, the detected biological information 101 is acquired and stored via the in-vehicle network 90. The biometric information 101 stored in the biometric information storage unit 12 is read by the user state determination unit 13 at a predetermined cycle. The user state determination unit 13 is a configuration unit that determines user state information 102 such as a user's hunger degree and fatigue degree based on the user preference information 100 and the biological information 101. A method for determining the user status information 102 will be described later. The user state storage unit 13 a is a storage unit that stores the user state information 102 obtained by the user state determination unit 13.
　目的地情報取得部１４は、目的地情報１０３を取得する構成部である。例えば、表示装置部１９に目的地の設定用画面を表示し、この設定用画面を基にナビゲーション装置１０に標準的に搭載された入力装置で目的地情報１０３を設定することが可能な、目的地情報１０３の設定用のＨＭＩとして実現される。目的地情報取得部１４が取得した目的地情報１０３は、車内ネットワーク９０を介してデータベース３０に登録される。また、目的地情報取得部１４が、データベース３０から過去に登録された目的地情報１０３を取得してもよい。 The destination information acquisition unit 14 is a component that acquires the destination information 103. For example, a destination setting screen can be displayed on the display unit 19, and the destination information 103 can be set with an input device that is normally mounted on the navigation device 10 based on the setting screen. This is realized as an HMI for setting the ground information 103. The destination information 103 acquired by the destination information acquisition unit 14 is registered in the database 30 via the in-vehicle network 90. Further, the destination information acquisition unit 14 may acquire the destination information 103 registered in the past from the database 30.
　時間情報取得部１５は、現在時刻や運転時間などの時間情報１０４を取得する構成部である。例えば、ナビゲーション装置１０として機能するコンピュータに搭載されたタイマを用いた計時手段である。時間情報記憶部１５ａは、時間情報取得部１５で得られた時間情報１０４を記憶する記憶部である。 The time information acquisition unit 15 is a configuration unit that acquires time information 104 such as the current time and driving time. For example, it is time measuring means using a timer mounted on a computer that functions as the navigation device 10. The time information storage unit 15 a is a storage unit that stores the time information 104 obtained by the time information acquisition unit 15.
　現在地情報取得部１６は、自車両の現在の走行地点などの現在地情報１０５を取得する構成部である。例えば、ＧＰＳ（Global Positioning System）や加速度センサから位置情報を取得して自車位置を測位する。装置制御部１７は、ユーザ趣向情報１００、ユーザ状態情報１０２、目的地情報１０３、時間情報１０４及び現在地情報１０５に基づいて、ユーザ側に提示する目的地や目的地までのルートなどの提示目的地情報１１０を決定する構成部である。 The current location information acquisition unit 16 is a component that acquires current location information 105 such as the current travel point of the host vehicle. For example, position information is acquired from GPS (Global Positioning System) or an acceleration sensor, and the vehicle position is measured. The device control unit 17 uses the user preference information 100, the user status information 102, the destination information 103, the time information 104, and the current location information 105 to present a destination such as a destination to be presented to the user and a route to the destination. It is a component that determines information 110.
　表示装置制御部１８は、装置制御部１７からの制御信号に従って提示目的地情報１１０の提示動作を制御する構成部である。表示装置部１９は、提示目的地情報１１０をユーザ側へ提示する構成部である。この表示装置部１９には、ナビゲーション装置に搭載されたＬＣＤ（Liquid Crystal Display）などの表示装置に加え、スピーカなどの音声出力装置も含まれる。例えば、提示目的地情報１１０に設定された目的地や目的地までのルートを示す地図情報や案内音声情報は、表示装置部１９の表示画面に表示され、スピーカから音声出力される。 The display device control unit 18 is a component that controls the presentation operation of the presentation destination information 110 in accordance with a control signal from the device control unit 17. The display unit 19 is a component that presents the presentation destination information 110 to the user side. The display unit 19 includes an audio output device such as a speaker in addition to a display device such as an LCD (Liquid Crystal Display) mounted on the navigation device. For example, the map information and the guidance voice information indicating the destination set in the presentation destination information 110 and the route to the destination are displayed on the display screen of the display unit 19 and are output as voice from a speaker.
　図３は、実施の形態１によるカーナビゲーションシステムに用いられる各種センサ及びデータベースの構成を示すブロック図である。図３（ａ）は、各種センサの構成を示しており、図３（ｂ）はデータベース３０の構成を示している。各種センサ２０には、図３（ａ）に示すように、生体情報１０１を検出する生体情報検出部２１が設けられる。
　この生体情報検出部２１は、例えば、ユーザを撮影するカメラ、ユーザの血圧を計測する血圧センサや体温を検出する温計センサなどに加え、これらの出力信号をナビゲーション装置１０側で処理可能な情報形態に変換して生体情報１０１を生成する処理手段を備える。 FIG. 3 is a block diagram showing configurations of various sensors and a database used in the car navigation system according to the first embodiment. FIG. 3A shows the configuration of various sensors, and FIG. 3B shows the configuration of the database 30. As shown in FIG. 3A, the various sensors 20 are provided with a biological information detection unit 21 that detects biological information 101.
The biological information detection unit 21 is, for example, information that can process these output signals on the navigation device 10 side in addition to a camera that captures the user, a blood pressure sensor that measures the blood pressure of the user, a thermometer sensor that detects body temperature, and the like.

　データベース３０には、ユーザ趣向情報１００を記憶する趣向情報記憶部３１及び目的地情報１０３を記憶する目的地情報記憶部３２が設けられる。データベース３０を記憶する記憶装置は、車内ネットワーク９０で接続された外部記憶装置であってもよいが、ナビゲーション装置１０に内蔵されたハードディスク装置の記憶領域に構築しても構わない。 The database 30 is provided with a preference information storage unit 31 that stores user preference information 100 and a destination information storage unit 32 that stores destination information 103. The storage device for storing the database 30 may be an external storage device connected via the in-vehicle network 90, but may be constructed in a storage area of a hard disk device built in the navigation device 10.
　次に動作について説明する。
　図４は、実施の形態１によるカーナビゲーションシステムで提示ルートが決定されるまでの情報の流れを示す図である。図２，３に示した構成と図４を参照して、カーナビゲーションシステム各部の主な動作を述べる。なお、以降では、運転者や同乗者が空腹や疲労状態にあるとき、このユーザ状態に予め関連付けられた目的地候補及びルートとして飲食店を含むルートを提示する場合を例に挙げる。 Next, the operation will be described.
FIG. 4 is a diagram showing a flow of information until a presentation route is determined in the car navigation system according to the first embodiment. The main operations of each part of the car navigation system will be described with reference to the configuration shown in FIGS. In the following, when the driver or passenger is hungry or tired, an example is given in which a route including a restaurant is presented as a destination candidate and a route associated in advance with the user state.
　先ず、運転前に前処理として、趣向情報取得部１１により、運転者及び同乗者のユーザ趣向情報１００をそれぞれ取得しておく。ユーザ趣向情報１００には、運転者や同乗者の性別、年齢、好きな食べ物のジャンル、通常食事（朝、昼、夜）を摂る時刻、外食の際の１食当たりの金額などがある。趣向情報取得部１１によって、これらの情報を設定項目とする入力用画面が表示装置部１９に表示される。ユーザは、設定項目に対応する情報を、端末キー入力又は音声入力で設定する。 First, as a pre-process before driving, the preference information acquisition unit 11 acquires user preference information 100 of a driver and a passenger. The user preference information 100 includes the gender, age, favorite food genre, time of eating a normal meal (morning, noon, night), the amount of money per meal when eating out, and the like. The preference information acquisition unit 11 displays an input screen having these pieces of information as setting items on the display unit 19. The user sets information corresponding to the setting item by terminal key input or voice input.
　このように入力されたユーザ趣向情報１００は、車内ネットワーク９０を介して、趣向情報取得部１１からデータベース３０の趣向情報記憶部３１に保持される。また、目的地情報１０３も同様に、車内ネットワーク９０を介して、目的地情報取得部１４からデータベース３０の目的地情報記憶部３２に登録される。 The user preference information 100 input in this way is held in the preference information storage unit 31 of the database 30 from the preference information acquisition unit 11 via the in-vehicle network 90. Similarly, the destination information 103 is also registered in the destination information storage unit 32 of the database 30 from the destination information acquisition unit 14 via the in-vehicle network 90.
　次に、運転中は、生体情報検出部２１が運転者や同乗者の生体情報１０１を検出する。
この生体情報検出部２１により車内のユーザから取得された生体情報１０１に基づいて、運転中のユーザの現状に即した適切な提示タイミングが決定される。ここでは、運転者や同乗者が空腹や疲労状態にある場合に適した提示タイミングを決定するために、生体情報検出部２１に、車内を撮影するカメラ、車内音を集音する集音マイク、血圧センサ、加速度センサ、温度センサ及びサーモグラフィ装置などを設け、これらが取得した情報を処理して生体情報１０１を生成する情報処理部を設けておく。 Next, during driving, the biological information detection unit 21 detects the biological information 101 of the driver and passengers.
Based on the biometric information 101 acquired from the user in the vehicle by the biometric information detection unit 21, an appropriate presentation timing in accordance with the current state of the driving user is determined. Here, in order to determine the presentation timing suitable when the driver or passenger is hungry or tired, the biological information detection unit 21 is provided with a camera that captures the interior of the vehicle, a sound collection microphone that collects the interior sound, A blood pressure sensor, an acceleration sensor, a temperature sensor, a thermographic device, and the like are provided, and an information processing unit that processes the information acquired by these to generate the biological information 101 is provided.
　生体情報検出部２１は、例えば、カメラで撮影した画像から、乗車人数を検出したり、各搭乗者の目が向いている方向を検出した結果を基に凝視時間を生体情報１０１として測定する。また、集音マイクが検出した車内音（話し声、空腹音）から空腹音を抽出して、運転者や同乗者の空腹状態を示す生体情報１０１を生成してもよい。さらに、生体情報検出部２１では、血圧センサをシートベルトなどに埋め込んでおき、運転者や同乗者の血圧を生体情報１０１として測定する。 The biometric information detection unit 21 measures the gaze time as the biometric information 101 based on the result of detecting the number of passengers or the direction in which each passenger's eyes are facing, for example, from an image captured by a camera. Moreover, the hungry sound may be extracted from the in-vehicle sound (speaking voice, hungry sound) detected by the sound collecting microphone, and the biological information 101 indicating the hungry state of the driver or the passenger may be generated. Further, the biological information detection unit 21 embeds a blood pressure sensor in a seat belt or the like, and measures the blood pressure of the driver or passenger as the biological information 101.
　また、人間は、空腹や疲労に起因して心理状態が不安定になると一定のリズムをとって気を紛らわせることがある。そこで、座席などに加速度センサを埋め込んでおけば、着席者が上述のリズムをとった際、その振動を検出することができる。つまり、加速度センサで取得された振動の検出情報を、運転者や同乗者の心理状態を推測する生体情報１０１として利用できる。 Also, human beings may be distracted with a certain rhythm when psychological state becomes unstable due to hunger and fatigue. Therefore, if an acceleration sensor is embedded in a seat or the like, the vibration can be detected when the seated person takes the rhythm described above. That is, the vibration detection information acquired by the acceleration sensor can be used as the biological information 101 for estimating the psychological state of the driver or passengers.
　さらに、温度センサ及びサーモグラフィ装置によって、搭乗者の頭部付近の体温を生体情報１０１として測定する。一般的に、心理状態に応じて皮膚血流量が変動すると、これによって皮膚温度分布が変化する。このため、体温情報を、運転者及び同乗者の心理状態を推測するための生体情報１０１として利用する。 Further, the body temperature near the head of the passenger is measured as the biological information 101 by the temperature sensor and the thermography device. In general, when the skin blood flow fluctuates according to the psychological state, the skin temperature distribution changes accordingly. For this reason, body temperature information is utilized as the biometric information 101 for estimating the psychological state of a driver and a passenger.
　生体情報１０１は、自車両の走行時に運転者及び同乗者から、生体情報検出部２１によって常時若しくは一定の周期で取得され、車内ネットワーク９０を経由して生体情報検出部２１からナビゲーション装置１０の生体情報記憶部１２に送られて保持される。また、時間情報取得部１５は、車内に設置した時計などから現在時刻を取得し、タイマなどから乗車時間などを取得して、時間情報１０４として時間情報記憶部１５ａに保持する。 The biological information 101 is acquired from the driver and passengers at the time of traveling of the host vehicle by the biological information detection unit 21 constantly or at a constant cycle, and is transmitted from the biological information detection unit 21 to the living body of the navigation device 10 via the in-vehicle network 90. It is sent to and held in the information storage unit 12. Further, the time information acquisition unit 15 acquires the current time from a clock or the like installed in the vehicle, acquires the boarding time from a timer or the like, and holds the time information 104 in the time information storage unit 15a.
　ユーザ状態判定部１３は、生体情報記憶部１２から各種の生体情報１０１を読み出し、時間情報記憶部１５ａから時間情報１０４を読み出し、趣向情報取得部１１で取得されたユーザ趣向情報１００を入力して、これらの情報１００，１０１，１０４に所定の演算を施すことにより、運転者及び同乗者のユーザ状態情報１０２をそれぞれ算出する。
　ここでは、生体情報１０１及び時間情報１０４、ユーザ趣向情報１００に対して所定のルールで評価する点数付けを行うことで、運転者又は同乗者の空腹度や疲労度を示す指標を求めることができる。 The user state determination unit 13 reads various biological information 101 from the biological information storage unit 12, reads time information 104 from the time information storage unit 15 a, and inputs the user preference information 100 acquired by the preference information acquisition unit 11. The user status information 102 of the driver and the passenger is calculated by performing a predetermined calculation on the information 100, 101, and 104, respectively.
Here, the biometric information 101, the time information 104, and the user preference information 100 are scored according to a predetermined rule, so that an index indicating the driver's or passenger's hunger or fatigue can be obtained. .
　例えば、生体情報１０１として取得された運転者又は同乗者の視線の凝視時間と、時間情報１０４が示す乗車時間から、下記式（１）を用いて運転者又は同乗者の疲労度Ｂを算出する。ただし、αは運転者か同乗者によって異なる係数である。
　疲労度Ｂ＝α×｛（凝視時間）／（乗車時間）｝　　　・・・（１） For example, the driver's or passenger's fatigue level B is calculated from the gaze time of the driver's or passenger's line of sight acquired as the biological information 101 and the boarding time indicated by the time information 104 using the following equation (1). . However, α is a coefficient that differs depending on the driver or passenger.
Fatigue degree B = α × {(gaze time) / (ride time)} (1)
　また、生体情報１０１として取得された車内音と血圧、振動、頭部付近の体温、時間情報１０４で示される現在時刻、ユーザ趣向情報１００として設定された通常の食事摂取時刻から、下記式（２）～（４）を用いて運転者又は同乗者の空腹度Ｈを算出できる。
　ただし、指標１は、空腹に対する苛立ち度合を示す指標値である。また、指標２とは、食事をとるタイミングの適正度合を示す指標値である。

　上述のように、各々の生体情報１０１、時間情報１０４、ユーザ趣向情報１００に対して点数化のルールを設定して、算出したものがユーザ状態情報１０２となる。このようにして求められた搭乗者ごとのユーザ状態情報１０２は、ユーザ状態記憶部１３ａに保持される。
　また、現在地情報取得部１６は、ＧＰＳや加速度センサのデータに基づいて車両の現在地情報１０５を取得する。 As described above, a rule for scoring is set for each of the biological information 101, the time information 104, and the user preference information 100, and the calculated value becomes the user status information 102. The user status information 102 for each passenger obtained in this way is held in the user status storage unit 13a.
The current location information acquisition unit 16 acquires the current location information 105 of the vehicle based on GPS and acceleration sensor data.
　装置制御部１７は、ある周期毎に、ユーザ趣向情報１００とユーザ状態情報１０２、目的地情報１０３、時間情報１０４、現在地情報１０５を用いて、提示目的地情報１１０を決定し、この決定結果を基に表示装置制御部１８を制御する。このように、生体情報１０１に基づいて、ユーザの現状に即した適切な提示タイミングで、提示目的地情報１１０が決定される。なお、装置制御部１７は、この動作の他に、ナビゲーション装置１０内の各構成部の動作も制御する。 The device control unit 17 determines the presentation destination information 110 using the user preference information 100, the user status information 102, the destination information 103, the time information 104, and the current location information 105 every certain period, and determines the determination result. Based on this, the display control unit 18 is controlled. As described above, the presentation destination information 110 is determined based on the biological information 101 at an appropriate presentation timing according to the current state of the user. Note that the device control unit 17 controls the operation of each component in the navigation device 10 in addition to this operation.
　次に、装置制御部１７による提示目的地情報１１０の決定方法の詳細を説明する。
　先ず、装置制御部１７は、ユーザ状態記憶部１３ａからユーザ状態情報１０２を読み出し、ユーザ状態情報１０２を構成する各指標値を、これら指標値を予め設定しておいた閾値と比較した閾値判定結果に応じて、提示目的地情報１１０の内容を決定する。ここでは、運転者や同乗者が空腹や疲労状態にあるとき、このユーザ状態に予め関連付けられた目的地候補及びルートとして飲食店を含むルートを提示する。 Next, details of a method of determining the presentation destination information 110 by the device control unit 17 will be described.
First, the apparatus control unit 17 reads the user state information 102 from the user state storage unit 13a, and compares the index values constituting the user state information 102 with threshold values set beforehand for these index values. The contents of the presentation destination information 110 are determined accordingly. Here, when a driver or a passenger is hungry or tired, a route including a restaurant is presented as a destination candidate and a route previously associated with the user state.
　例えば、ユーザ状態情報１０２における空腹度Ｈや疲労度Ｂが閾値よりも高い人数を求め、空腹度Ｈの高い人数が多ければ、提示候補１０６の目的ジャンルを、レストラン等の飲食店に設定する。また、疲労度Ｂの高い人数が多ければ、喫茶店等の飲食店を設定し、同数であれば、レストラン等の飲食店に設定する。さらに、ユーザ状態情報１０２から空腹度Ｈが最も高いユーザを、提示候補１０６の目的地対象ユーザに設定する。 For example, the number of persons whose hunger degree H or fatigue degree B in the user state information 102 is higher than a threshold value is obtained, and if there are many persons with a high hunger degree H, the target genre of the presentation candidate 106 is set to a restaurant or the like restaurant. Moreover, if there are many people with high fatigue degree B, restaurants, such as a coffee shop, will be set, and if it is the same number, it will set to restaurants, such as a restaurant. Further, the user having the highest hunger degree H from the user status information 102 is set as the destination target user of the presentation candidate 106.
　続いて、装置制御部１７は、目的地情報記憶部３２が記憶する目的地情報１０３から、提示候補１０６の目的ジャンルとマッチングする目的地情報１０３を取得し、この目的地情報１０３を目的地内容解析結果１０７とする。さらに、装置制御部１７は、提示候補１０６の目的地対象ユーザとマッチングするユーザ趣向情報１００を取得し、このユーザ趣向情報１００をユーザ趣向内容解析結果１０８とする。 Subsequently, the device control unit 17 acquires the destination information 103 that matches the destination genre of the presentation candidate 106 from the destination information 103 stored in the destination information storage unit 32, and uses this destination information 103 as the destination content. The analysis result 107 is assumed. Furthermore, the device control unit 17 acquires user preference information 100 that matches the destination target user of the presentation candidate 106, and uses the user preference information 100 as the user preference content analysis result 108.
　また、装置制御部１７は、現在地情報１０５と目的地内容解析結果１０７の住所より、不図示の地図データベースから取得した地図情報を用いて現在地から目的地までのルート検索を行い、ルート検索結果１０９を求める。
　この後、装置制御部１７は、時間情報１０４の現在時刻と目的地内容解析結果１０７、ユーザ趣向内容解析結果１０８、ルート検索結果１０９から、閾値判定に応じた点数付けにより提示目的地情報１１０を決定する。 Further, the device control unit 17 performs a route search from the current location to the destination from the current location information 105 and the address of the destination content analysis result 107 using map information acquired from a map database (not shown), and obtains a route search result 109. Ask for.
Thereafter, the device control unit 17 obtains the presentation destination information 110 from the current time of the time information 104, the destination content analysis result 107, the user preference content analysis result 108, and the route search result 109 by scoring according to threshold determination. decide.
　ここで、飲食店を目的地とした提示目的地情報１１０を決定する場合を説明する。
　例えば、現在時刻と、目的地内容解析結果１０７に規定される料理ジャンル、利用年代、性別、営業時間、平均料金、ユーザ趣向内容解析結果１０８に設定される年齢、性別、好きな食べ物ジャンル、外食にかける費用、ルート検索結果１０９の目的地までの所要時間から、ユーザの趣向に合致する飲食店が決定される。 Here, the case where the presentation destination information 110 with the restaurant as the destination is determined will be described.
For example, the current time, the cooking genre specified in the destination content analysis result 107, age of use, gender, business hours, average fee, age set in the user preference content analysis result 108, gender, favorite food genre, restaurant The restaurant that matches the user's taste is determined from the cost to spend and the required time to the destination of the route search result 109.
　具体的には、下記式（５）～（７）を用いて、提示判定値Ａを算出する。
　ただし、指標３は、店の好みを示す指標値である。また、指標４は、店の一般度を示す指標値である。
　γ１は、店の好みを示す指標３に対する係数であり、γ２は、店の一般度を示す指標４に対する係数である。
　また、ｃ１は、料理ジャンルと好きな食べ物ジャンルの相関度に対する係数である。
　ｃ２は、ユーザが外食にかける費用が平均料金に含まれる場合が“１”となる指標値に対する係数である。費用が平均料金に含まれない場合、指標値は“０”になる。
　ｄ１は、年齢が利用年代に含まれる場合が“１”となる指標値に対する係数である。年齢が利用年代に含まれない場合、指標値は“０”になる。
　ｄ２は、性別が利用性別に含まれる場合が“１”となる指標値に対する係数である。性別が利用性別に含まれない場合、指標値は“０”になる。
　ｄ３は、現在時刻と所要時間の和が営業時間内の場合である場合が“１”となる指標値に対する係数である。上記時間の和が営業時間内でなければ、指標値は“０”になる。
　ｄ４は、所要時間が閾値時間以内の場合が“１”となる指標値に対する係数である。所要時間が閾値時間を超える場合、指標値は“０”になる。
　なお、γ１，γ２、ｃ１～ｃ２、ｄ１～ｄ４は、運転者又は同乗者によって各々異なる係数である。
　提示判定値Ａ＝（γ１×指標３）＋（γ２×指標４）　　　・・・（５）
　指標３＝｛ｃ１×（料理ジャンルと好きな食べ物ジャンルの相関度）＋｛ｃ２×（外食にかける費用が平均料金に含まれる場合＝１）｝　　　・・・（６）
　指標４＝｛ｄ１×（年齢が利用年代に含まれる場合＝１）｝＋｛ｄ２×（性別が利用性別に含まれる場合＝１）｝＋｛ｄ３×（現在時刻と所要時間の和が営業時間内の場合である場合＝１）｝＋｛ｄ４×（所要時間が閾値時間以内の場合＝１）｝　　　・・・（７） Specifically, the presentation determination value A is calculated using the following formulas (5) to (7).
However, the index 3 is an index value indicating the preference of the store. The index 4 is an index value indicating the general degree of the store.
γ1 is a coefficient for the index 3 indicating the preference of the store, and γ2 is a coefficient for the index 4 indicating the general degree of the store.
C1 is a coefficient for the degree of correlation between the cooking genre and the favorite food genre.
c2 is a coefficient for an index value that is “1” when the average fee includes the cost of eating out by the user. When the cost is not included in the average fee, the index value is “0”.
d1 is a coefficient for the index value that is “1” when the age is included in the usage age. When the age is not included in the usage age, the index value is “0”.
d2 is a coefficient for the index value that is “1” when the gender is included according to the usage. If the gender is not included by gender, the index value is “0”.
d3 is a coefficient for the index value that is “1” when the sum of the current time and the required time is within business hours. If the sum of the above times is not within business hours, the index value is “0”.
d4 is a coefficient for the index value that is “1” when the required time is within the threshold time. When the required time exceeds the threshold time, the index value becomes “0”.
Note that γ1, γ2, c1 to c2, and d1 to d4 are different coefficients depending on the driver or the passenger.
Presentation determination value A = (γ1 × index 3) + (γ2 × index 4) (5)
Index 3 = {c1 × (degree of correlation between cooking genre and favorite food genre) + {c2 × (when the cost for eating out is included in the average price = 1)} (6)
Index 4 = {d1 × (when age is included in usage age = 1)} + {d2 × (when gender is included according to usage = 1)} + {d3 × (sum of current time and required time is open When it is within the time = 1)} + {d4 × (when the required time is within the threshold time = 1)} (7)
　装置制御部１７は、上述した手順で、提示候補１０６の目的ジャンルとマッチングする目的地の各々に対して提示判定値Ａを算出し、ユーザに提示する店を決定する。なお、提示する店の最大数は任意に設定する。
　表示装置制御部１８は、装置制御部１７により決定された提示目的地情報１１０から、各目的地の提示判定値Ａが高い順に、提示目的地情報１１０に設定された画像や画像の提示理由を説明する音声を提示するよう表示装置部１９を制御する。例えば、提示判定値Ａが所定の閾値以上であれば、提示対象の店とする。 The device control unit 17 calculates a presentation determination value A for each destination that matches the target genre of the presentation candidate 106 in the above-described procedure, and determines a store to be presented to the user. The maximum number of shops to be presented is arbitrarily set.
The display device control unit 18 displays the images set in the presentation destination information 110 and the reasons for presentation of the images in descending order of the presentation determination value A of each destination from the presentation destination information 110 determined by the device control unit 17. The display device unit 19 is controlled to present a voice to be explained. For example, if the presentation determination value A is equal to or greater than a predetermined threshold value, the shop is a presentation target.
　この後、ユーザは、端末キー入力又は音声入力などで、提示目的地から目的地を決定（キャンセル）し、ルート案内を開始（実施しない）する。目的地が決定されると、ナビゲーション装置１０は、既に開始されている目的地へのルート案内を終了する。 After this, the user determines (cancels) the destination from the presentation destination by terminal key input or voice input, and starts (does not implement) route guidance. When the destination is determined, the navigation apparatus 10 ends the route guidance to the destination that has already been started.
　以上のように、この実施の形態１によれば、車両に搭乗するユーザの生体情報１０１から算出したユーザ状態情報１０２を示す指標値を所定の閾値と比較して、ユーザの現状に変化が発生したことを判定すると、当該状態に予め対応付けた目的地候補及び経路をユーザに提示する。このように構成することにより、目的地候補及びそのルートへの変更をユーザが操作することなく、能動的にナビゲーション装置１０が行うことで、ユーザ操作の手間を省き、ユーザの趣向に合致する目的地への案内が可能となる。
　また、ユーザ趣向情報１００及び生体情報１０１を利用するため、ユーザの現状に即した適切な提示タイミングで、ユーザの趣向に合致した目的地候補の提示及びルート変更を行うことができる。 As described above, according to the first embodiment, the index value indicating the user state information 102 calculated from the biological information 101 of the user on the vehicle is compared with the predetermined threshold value, and a change occurs in the current state of the user. If it is determined, the destination candidate and route previously associated with the state are presented to the user. With this configuration, the navigation device 10 actively performs the destination candidate and the change to the route without the user's operation, so that the user's operation is saved, and the purpose matches the user's preference. Guidance to the ground is possible.
In addition, since the user preference information 100 and the biometric information 101 are used, it is possible to present a destination candidate that matches the user preference and change the route at an appropriate presentation timing in accordance with the current state of the user.
　なお、上記実施の形態１では、ユーザ趣向情報１００及び生体情報１０１に基づいて、目的地決定やルート変更を行う場合を示したが、この構成に限定されるものではない。
　例えば、趣向情報取得部１１を省略し、装置制御部１７が、運転中にユーザから順次検出される生体情報１０１に基づいて提示タイミングを決定する。この提示タイミングで、装置制御部１７が、時間情報１０４の現在時刻と目的地内容解析結果１０７、ルート検索結果１０９から提示目的地情報１１０を決定し、表示装置制御部１８を制御してユーザに提示する。このように構成することでも、ユーザの現状に即した適切な提示タイミングで、目的地及びルート変更を行うことができる。 In the first embodiment, the case where the destination is determined and the route is changed based on the user preference information 100 and the biological information 101 has been described. However, the present invention is not limited to this configuration.
For example, the preference information acquisition unit 11 is omitted, and the device control unit 17 determines the presentation timing based on the biological information 101 sequentially detected from the user during driving. At this presentation timing, the device control unit 17 determines the presentation destination information 110 from the current time of the time information 104, the destination content analysis result 107, and the route search result 109, and controls the display device control unit 18 to inform the user. Present. Even with this configuration, it is possible to change the destination and route at an appropriate presentation timing according to the current state of the user.

The main operation of each part of the car navigation system will be described with reference to FIGS.
As in the first embodiment, the route including the restaurant is presented as the presentation destination information 110 at the timing when the driver or passenger is determined to be hungry or tired based on the biometric information 101. Take the case as an example.
When the driver or passenger is hungry or tired, the communication control unit 20 wirelessly communicates the destination additional information 111 such as the in-store image relating to the destination information 103 and the service of the store currently being executed by the wireless server 70. Get from.
In addition, the communication control unit 20 similarly acquires other user evaluation information 112 such as satisfaction with the store with respect to the destination information 103 from the other navigation device 40.

This destination additional information 111 is added to an image, sound, or the like presented on the display unit 19.
The out-of-vehicle server 70 creates and manages the destination additional information 111 from information provided from the outside. The information content that can be provided to the outside server 70 may be set according to, for example, an advertisement fee paid to the administrator of the outside server 70.
　他ユーザ評価情報１１２は、装置制御部１７によりユーザに提示する店が決定されたことを契機に、通信制御部２０が、ユーザ趣向内容解析結果１０８と同じ年代（年齢差がある閾値内）、性別、好きな食べ物ジャンルを有する他ユーザの評価情報として他ナビゲーション装置４０から取得したものである。この他ユーザ評価情報１１２は、装置制御部１７による提示判定値の計算に利用される。 The other user evaluation information 112 is the same age as the user preference content analysis result 108 (within an age difference threshold) when the device control unit 17 determines the store to be presented to the user. It is acquired from the other navigation apparatus 40 as evaluation information of other users who have sex and favorite food genres. The other user evaluation information 112 is used for the calculation of the presentation determination value by the device control unit 17.
　このように、実施の形態２によるナビゲーション装置１０では、目的地（候補地）及びルート変更で提示する情報として、車外通信によって車外サーバ７０から取得した目的地（候補地）で提供される情報が含まれる。また、目的地（候補地）及びルート変更を提示する際に、車外通信によって他ナビゲーション装置４０から取得した同じ趣向を持つ他ユーザによる当該目的地に対する評価が利用される。なお、車外サーバ７０及び他ナビゲーション装置４０から取得する情報１１１，１１２は、課金制により提供され、金額に応じて提示可能内容が異なるように構成してもよい。 As described above, in the navigation device 10 according to the second embodiment, the information provided by the destination (candidate place) acquired from the outside server 70 by the outside communication is used as the information presented by the destination (candidate place) and the route change. included. Moreover, when presenting a destination (candidate place) and a route change, the evaluation for the destination by another user having the same taste acquired from the other navigation device 40 by external communication is used. Note that the information 111 and 112 acquired from the out-of-vehicle server 70 and the other navigation device 40 may be provided by a charging system and may be configured so that the contents that can be presented differ according to the amount of money.
