The text database 20 stores text data for recognizing the user's utterance content, for use in the processing of the ambiguity determination unit 21 and the route analysis unit 22. The text database 20 also includes a relative phrase database 31 in which relative phrases are registered. The relative word / phrase database 31 is used by the ambiguity determination unit 21 to determine whether or not the user's speech includes an ambiguity, and the route analysis unit 22 to analyze the route for the user's command including the ambiguity. Be For example, as shown in FIG. 2, in the relative word / phrase database 31, relative words and information about search criteria, search directions, and search conditions when those words are inputted are registered.
相対的語句データベース31には、例えば、図2に示されるように、相対的語句として、「さっき」「前」「今」「通り過ぎた」「行き過ぎた」「このあたり」などの複数の語句が登録され、それぞれの語句に対して、検索を行う場合の検索基準となる位置、検索方向、検索条件に関する情報が登録されている。例えば、相対的語句である「通り過ぎた」に対しては、検索基準として「現在位置」が登録され、検索方向として「走行履歴」が登録され、検索条件として「過去Bメートル」が登録されている。すなわち、相対的語句である「通り過ぎた」に対しては、車両の現在位置を基準として、走行履歴を参照して求められる検索方向に過去Bメートルの範囲内が検索されることが登録されている。検索条件となる「過去Bメートル」の範囲については、例えば、「さっき」であれば過去100メートル、「通り過ぎた」であれば過去500メートルなど、語句によって適切と思われる数値が適用される。
In the relative word / phrase database 31, for example, as shown in FIG. 2, as the relative word / phrase, a plurality of words such as "previously", "before", "now", "passed over", "overpassed" and "around" are Information regarding the position, the search direction, and the search condition, which is registered and which becomes a search criterion when performing a search, is registered for each word / phrase. For example, for the relative phrase “passed by,” “current position” is registered as a search criterion, “travel history” is registered as a search direction, and “past B meters” is registered as a search condition. There is. That is, for the relative phrase “passed by”, it is registered that within the range of the past B meters is searched in the search direction determined with reference to the travel history based on the current position of the vehicle There is. For the range of "past B meters" as a search condition, for example, a numerical value that is considered appropriate according to a phrase is applied, such as the past 100 meters for "previous" and the past 500 meters for "pass by".
図2に示される相対的語句データベース31には、例えば、「さっき」「前」「今」「通り過ぎた」「行き過ぎた」などの、絶対的ではなく相対的に過去の時間や経路を表す語句が含まれていると好適である。例えば、「○○m前」「○○分前」などの語句も、絶対的な地点の指定(例えば、銀行、交差点など)とは異なり、ある地点からの相対的な距離や、ある地点を走行していた時からの相対的な時刻を示す、相対的な、すなわち、あいまいさを有する語句である。また、相対的語句データベース31には、例えば、「この(現在地の)あたり」「(現在地の)ちかく」「○○の近く」「××の先」「××の手前」など、絶対的な地点の指定ではなく、ある地点からの相対的な位置関係を示す語句が含まれていると好適である。相対的語句データベース31には、図2に示される以外の情報が登録されていてもよいことは言うまでもない。
In the relative word / phrase database 31 shown in FIG. 2, for example, words representing relatively past time and route, not absolute, such as "previously", "before", "now", "passed over" and "overdue". Is preferably included. For example, words such as "○ ○ m ago" and "○ o minutes ago" are also different from the absolute point designation (eg, bank, intersection, etc.), and the relative distance from a certain point or a certain point It is a relative or ambiguity phrase that indicates the relative time from when you were traveling. Also, in the relative word / phrase database 31, for example, “this (at the present location)”, “(at the current location)”, “near xxx”, “ear of xx”, “early of xx”, etc. are absolute It is preferable that a word indicating relative positional relationship from a certain point is included instead of designation of the point. It goes without saying that information other than that shown in FIG. 2 may be registered in the relative word / phrase database 31.

In addition, in FIG. 1, although each function structure was demonstrated as what one navigation apparatus 1 has, these may be comprised by several apparatus. For example, the touch panel 13, the speaker 24, the operation input unit 14, or the microphone 16 may be configured as an apparatus independent of the other components, and each may be capable of exchanging information.
このように、ナビゲーション装置1は、車両の現在位置を取得する現在位置情報取得部11と、入力機器(タッチパネル13、操作入力部14、マイク16)を制御してユーザからの指令を取り込む入力制御部15および音声データ取得部17と、入力制御部15が取り込んだユーザの指令に相対的な語句が含まれているかを判定するあいまいさ判定部21と、あいまいさ判定部21による判定結果、および、現在位置情報取得部11により取得された車両の現在位置に基づいて、目的地を推定し、ルートを解析するルート解析部22と、ルート解析部による解析結果の出力を制御する音声データ出力制御部23および表示制御部25とを含む構成を有する。これにより、ナビゲーション装置1は、あいまいさを含む語句から、ユーザが目的とする進路を推定し、ルート検索して、その結果をユーザに提示することができる。

次に、図3~図9を参照し、ユーザからの指令にあいまいさが含まれている場合のルート解析の具体的な例について説明する。
Next, with reference to FIGS. 3 to 9, a specific example of the route analysis in the case where the command from the user includes an ambiguity will be described.
例えば、ナビゲーション装置1を搭載する車両が図3のXに示される位置であり、車両の走行履歴が点線で示される状態である場合に、ユーザが、「さっきまがった交差点の100m前まで戻る」と発話した場合について説明する。
For example, when the vehicle equipped with the navigation device 1 is at the position shown by X in FIG. 3 and the traveling history of the vehicle is in the state shown by the dotted line, the user “returns to 100 m before the intersection which has just been made” The case where the user utters
ユーザの発話「さっきまがった交差点の100m前まで戻る」は、マイク16により集音され、音声データ取得部17により取得され、音声解析処理部18に供給される。音声解析処理部18は、供給された音声データに対する音声解析処理を行い、解析結果をあいまいさ判定部21に供給する。
The user's speech “return to 100 m before the intersection where it was last” is collected by the microphone 16, acquired by the audio data acquisition unit 17, and supplied to the audio analysis processing unit 18. The voice analysis processing unit 18 performs voice analysis processing on the supplied voice data, and supplies the analysis result to the ambiguity determination unit 21.
あいまいさ判定部21は、相対的語句データベース31に登録されている相対的語句が含まれているか否かに基づいて、音声解析処理部18から供給された、ユーザの指令に対応する「さっきまがった交差点の100m前まで戻る」にあいまいさが含まれるか否かを判定する。「さっきまがった交差点の100m前まで戻る」には、「さっき」「100m前」「戻る」の相対的語句が含まれている。
The ambiguity determination unit 21 responds to the user's command supplied from the speech analysis processing unit 18 based on whether or not the relative phrase registered in the relative phrase database 31 is included. It is determined whether or not “return to 100 m before the intersection” includes ambiguity. "Return to 100 m before the intersection you have made" includes the relative phrases "preceding", "100 m before" and "return".
あいまいさ判定部21は、ユーザの指令に対応する情報とともに、あいまいさの判定結果をルート解析部22に供給する。ルート解析部22は、ユーザからの指令にあいまいさが含まれている場合、相対的語句データベース31に登録されている情報に基づいて、ルート解析を実行する。すなわち、「さっき」の語句は過去の時間を示しており、あいまいさ判定部21が、このような過去の時間を示す語句を抽出した場合に、ルート解析部22は、走行履歴記録部12に記録されている走行履歴を参照し、ルート解析を実行する。また、「通り過ぎた」などの語句は過去の経路を示しており、あいまいさ判定部21が、このような過去の時間を示す語句を抽出した場合に、ルート解析部22は、同様に走行履歴記録部12に記録されている走行履歴を参照し、ルート解析を実行する。
The ambiguity determination unit 21 supplies the determination result of the ambiguity to the route analysis unit 22 together with the information corresponding to the user's command. The route analysis unit 22 executes route analysis based on the information registered in the relative word / phrase database 31 when the command from the user contains an ambiguity. That is, the word “preceding” indicates a past time, and when the ambiguity determination unit 21 extracts a word indicating such a past time, the route analysis unit 22 causes the travel history recording unit 12 to Route analysis is performed with reference to the recorded travel history. Moreover, words and phrases such as "passed over" indicate a past route, and when the ambiguity judgment unit 21 extracts words and phrases indicating such a past time, the route analysis unit 22 similarly calculates the travel history.

That is, the route analysis unit 22 refers to the travel history recorded in the travel history recording unit 12 and extracts the extraction point A which is a “preceding intersection”. Then, the route analysis unit 22 refers to the traveling history recorded in the traveling history recording unit 12 to detect the traveling direction when the vehicle is traveling at the extraction point A, and returns 100 m from the extraction point A, that is, The extraction point B moved 100 m from the extraction point A to the opposite side of the traveling direction is recognized as the user's destination, and the route to the extraction point B is analyzed.
ルート解析部22は、ルートの解析結果を、音声データ出力制御部23および表示制御部25に供給する。音声データ出力制御部23は、ルート解析部22から供給されたルート解析結果を音声データに変換し、スピーカー24からの音声データの出力を制御する。表示制御部25は、タッチパネル13を制御して、ルート解析部22から供給されたルート解析結果の表示出力を制御する。
The route analysis unit 22 supplies the analysis result of the route to the audio data output control unit 23 and the display control unit 25. The audio data output control unit 23 converts the route analysis result supplied from the route analysis unit 22 into audio data, and controls the output of the audio data from the speaker 24. The display control unit 25 controls the touch panel 13 to control the display output of the route analysis result supplied from the route analysis unit 22.
このように、ナビゲーション装置1においては、走行履歴記録部12に記録されている走行履歴を参照し、車両がある地点を走行していた時の進行方向を検出することができるようにしたので、「戻る」というあいまいさを含む相対的な語句が含まれている場合においても、走行した経路をそのまま戻るような指示を行うのではなく、ユーザが意図する目的地への最適なルートを検索することが可能となる。
As described above, in the navigation device 1, the traveling direction recorded when the vehicle is traveling at a point can be detected by referring to the traveling history recorded in the traveling history recording unit 12. Even when the relative phrase including the ambiguity of "return" is included, search for the optimal route to the destination intended by the user, instead of giving an instruction to return the traveled route as it is It becomes possible.

ルート解析部22は、2つのルートの解析結果を、音声データ出力制御部23および表示制御部25に供給する。音声データ出力制御部23は、ルート解析部22から供給されたルート解析結果を音声データに変換し、スピーカー24からの音声データの出力を制御する。表示制御部25は、タッチパネル13を制御して、ルート解析部22から供給されたルート解析結果(図5において、ルート解析結果(1)およびルート解析結果(2)と示す)の表示出力を制御する。このとき、表示制御部25は、タッチパネル13を制御して、直近に通り過ぎたコンビニである抽出ポイントA1を基に検索されるルート解析結果(1)を優先して表示させるものとしてもよく、複数の候補があることをユーザに通知させるようにしてもよい。また、音声データ出力制御部23も、直近に通り過ぎたコンビニである抽出ポイントA1を基に検索されるルート解析結果(1)を優先してユーザに通知する音声出力を、スピーカー24から行わせるものとしてもよく、複数の候補があることをユーザに通知させるようにしてもよい。
The route analysis unit 22 supplies the analysis result of the two routes to the audio data output control unit 23 and the display control unit 25. The audio data output control unit 23 converts the route analysis result supplied from the route analysis unit 22 into audio data, and controls the output of the audio data from the speaker 24. The display control unit 25 controls the touch panel 13 to control the display output of the route analysis result (shown as route analysis result (1) and route analysis result (2) in FIG. 5) supplied from the route analysis unit 22. Do. At this time, the display control unit 25 may control the touch panel 13 to preferentially display the route analysis result (1) searched based on the extraction point A1, which is a convenience store that has passed most recently, The user may be notified that there is a candidate for In addition, the audio data output control unit 23 also causes the speaker 24 to perform audio output for notifying the user of the route analysis result (1), which is searched based on the extraction point A1 which is a convenience store that has passed most recently. Alternatively, the user may be notified that there are a plurality of candidates.
このように、ナビゲーション装置1においては、あいまいさを含む相対的な語句が含まれている場合のルート解析結果を複数求めることが可能となる。
Thus, in the navigation device 1, it is possible to obtain a plurality of route analysis results in the case where relative phrases including ambiguity are included.
次に、例えば、ナビゲーション装置1を搭載する車両が図6のXに示される位置であり、車両の走行履歴が点線で示される状態である場合に、ユーザが、「ひとつ前の交差点を右」と発話した場合について説明する。
Next, for example, when the vehicle equipped with the navigation device 1 is at a position indicated by X in FIG. 6 and the travel history of the vehicle is indicated by a dotted line, the user “rights one intersection ahead” The case where the user utters
ユーザの発話「ひとつ前の交差点を右」は、マイク16により集音され、音声データ取得部17により取得され、音声解析処理部18に供給される。音声解析処理部18は、供給された音声データに対する音声解析処理を行い、解析結果をあいまいさ判定部21に供給する。
The speech of the user “right at the intersection one before” is collected by the microphone 16, acquired by the audio data acquisition unit 17, and supplied to the audio analysis processing unit 18. The voice analysis processing unit 18 performs voice analysis processing on the supplied voice data, and supplies the analysis result to the ambiguity determination unit 21.
あいまいさ判定部21は、相対的語句データベース31に登録されている相対的語句が含まれているか否かに基づいて、音声解析処理部18から供給された、ユーザの指令に対応する「ひとつ前の交差点を右」にあいまいさが含まれるか否かを判定する。「ひとつ前の交差点を右」には、「前」の相対的語句が含まれている。
The ambiguity determination unit 21 receives the “previous one” corresponding to the user's command supplied from the voice analysis processing unit 18 based on whether or not the relative phrase registered in the relative phrase database 31 is included. It is determined whether an ambiguity is included in the “right intersection of”. The phrase "right one intersection ahead" includes the relative phrase "before".
あいまいさ判定部21は、ユーザの指令に対応する情報とともに、あいまいさの判定結果をルート解析部22に供給する。ルート解析部22は、ユーザからの指令にあいまいさが含まれている場合、相対的語句データベース31に登録されている情報に基づいて、必要に応じて、走行履歴記録部12に記録されている走行履歴を参照し、ルート解析を実行する。
The ambiguity determination unit 21 supplies the determination result of the ambiguity to the route analysis unit 22 together with the information corresponding to the user's command. The route analysis unit 22 is recorded in the travel history recording unit 12 as needed based on the information registered in the relative word / phrase database 31 when the instruction from the user includes an ambiguity. Perform route analysis with reference to travel history.
すなわち、ルート解析部22は、走行履歴記録部12に記録されている走行履歴を参照し、「ひとつ前の交差点」である抽出ポイントAを抽出する。そして、ルート解析部22は、走行履歴記録部12に記録されている走行履歴を参照し、車両が抽出ポイントAを走行していた時の進行方向を検出し、抽出ポイントAで右に曲がった場合の抽出ポイントBをユーザの目的地と認識して、抽出ポイントBへのルートを解析する。
That is, the route analysis unit 22 refers to the travel history recorded in the travel history recording unit 12 and extracts the extraction point A which is “one intersection ahead”. Then, the route analysis unit 22 refers to the traveling history recorded in the traveling history recording unit 12 and detects the traveling direction when the vehicle is traveling at the extraction point A, and turns to the right at the extraction point A The case extraction point B is recognized as the user's destination, and the route to the extraction point B is analyzed.
このようなあいまいな語句を含んでルートを検索した場合、特に、「ひとつ前の交差点を右」のように、所定の地点からの進行方向だけが示された場合には、ユーザの目的地は、抽出ポイントBであるのか、間違えずに「ひとつ前の交差点を右」に直進した場合の進路の先にあるのかを判断することは困難である。そこで、ルート解析部22は、走行履歴記録部12に記録されている走行履歴を参照し、間違えずに「ひとつ前の交差点を右」に直進した場合の進路に、現在位置から早く到着可能な地点が存在するか否かを検索する。この場合、間違えずに「ひとつ前の交差点を右」に曲がった後直進した場合の進路に、現在位置から早く到着可能な抽出ポイントCが存在するので、ルート解析部22は、抽出ポイントCをユーザの目的地候補の一つと認識して、抽出ポイントCへのルートを解析する。
When a route is searched including such ambiguous words and phrases, especially when only the direction of travel from a predetermined point is indicated, such as “right at the previous intersection,” the destination of the user is It is difficult to determine if it is the extraction point B or if it is ahead of the course when going straight to "right one intersection" without making a mistake. Therefore, the route analysis unit 22 can arrive early from the current position on the route when going straight ahead "right one intersection" with reference to the traveling history recorded in the traveling history recording unit 12 without mistake Search for the existence of a point. In this case, since the extraction point C which can arrive early from the current position is present in the course when going straight ahead after turning right to the one intersection ahead without mistake, the route analysis unit 22 extracts the extraction point C The route to the extraction point C is analyzed, recognizing it as one of the user's destination candidates.
ルート解析部22は、2つのルートの解析結果を、音声データ出力制御部23および表示制御部25に供給する。音声データ出力制御部23は、ルート解析部22から供給されたルート解析結果を音声データに変換し、スピーカー24からの音声データの出力を制御する。表示制御部25は、タッチパネル13を制御して、ルート解析部22から供給されたルート解析結果を表示出力させる。
The route analysis unit 22 supplies the analysis result of the two routes to the audio data output control unit 23 and the display control unit 25. The audio data output control unit 23 converts the route analysis result supplied from the route analysis unit 22 into audio data, and controls the output of the audio data from the speaker 24. The display control unit 25 controls the touch panel 13 to display and output the route analysis result supplied from the route analysis unit 22.
このように、ナビゲーション装置1においては、あいまいな語句を含んでルートを検索した場合に、ユーザの目的地が、あいまいな語句を含んだ指令により示される抽出ポイントBのみならず、間違えずに「ひとつ前の交差点を左」に直進した場合の進路の先にある抽出ポイントCのいずれである場合も、最適なルートを検索して、ユーザに提示することが可能となる。
Thus, in the navigation device 1, when the route is searched by including the ambiguous word / phrase, the destination of the user is not only the extraction point B indicated by the command which includes the ambiguous word / phrase, without mistake. In any of the extraction points C ahead of the route when going straight ahead one intersection to the left, it is possible to search for the optimal route and present it to the user.
次に、例えば、ナビゲーション装置1を搭載する車両が図7のXに示される位置であり、車両の走行履歴が点線で示される状態である場合に、ユーザが、「このあたりの銀行の角を左」と発話した場合について説明する。
Next, for example, when the vehicle equipped with the navigation device 1 is at the position shown by X in FIG. 7 and the travel history of the vehicle is in the state shown by the dotted line, the user The case of uttering "left" will be described.
ユーザの発話「このあたりの銀行の角を左」は、マイク16により集音され、音声データ取得部17により取得され、音声解析処理部18に供給される。音声解析処理部18は、供給された音声データに対する音声解析処理を行い、解析結果をあいまいさ判定部21に供給する。
The user's speech “the corner of the bank around this is left” is collected by the microphone 16, acquired by the audio data acquisition unit 17, and supplied to the audio analysis processing unit 18. The voice analysis processing unit 18 performs voice analysis processing on the supplied voice data, and supplies the analysis result to the ambiguity determination unit 21.
あいまいさ判定部21は、ユーザからのナビゲーションの指令の中に相対的語句データベース31に登録されている相対的語句が含まれているか否かに基づいて、音声解析処理部18から供給された、ユーザの指令に対応する「このあたりの銀行の角を左」にあいまいさが含まれるか否かを判定する。「このあたりの銀行の角を左」には、「このあたり」の相対的語句が含まれている。
The ambiguity determination unit 21 is supplied from the voice analysis processing unit 18 based on whether or not the relative phrase registered in the relative phrase database 31 is included in the navigation instruction from the user. It is determined whether or not an ambiguity is included in "left corner of the bank" corresponding to the user's command. The "left bank corner" includes the relative phrase "around".
あいまいさ判定部21は、ユーザの指令に対応する情報とともに、あいまいさの判定結果をルート解析部22に供給する。ルート解析部22は、ユーザからの指令にあいまいさが含まれている場合、相対的語句データベース31に登録されている情報に基づいて、ルート解析を実行する。すなわち、「このあたり」の語句は相対的な位置関係を示しており、あいまいさ判定部21がこのような相対的な位置関係を示す語句を抽出した場合に、ルート解析部22は、地図データベースを参照し、ルート解析を実行する。
The ambiguity determination unit 21 supplies the determination result of the ambiguity to the route analysis unit 22 together with the information corresponding to the user's command. The route analysis unit 22 executes route analysis based on the information registered in the relative word / phrase database 31 when the command from the user contains an ambiguity. That is, the phrase “in this case” indicates a relative positional relationship, and when the ambiguity determination unit 21 extracts a phrase that indicates such a relative positional relationship, the route analysis unit 22 determines that the map database Refer to and perform route analysis.
すなわち、ルート解析部22は、相対的語句データベース31に登録されている内容に基づいて、「このあたりの銀行」を、現在位置を基準として、所定範囲内で検索する。その結果、ルート解析部22は、「このあたりの銀行」である抽出ポイントA1および抽出ポイントA2を抽出する。そして、抽出ポイントA1として抽出された銀行の「角」である抽出ポイントB1は、現在の進行方向に存在するので、ルート解析部22は、通常のルート解析方法を用いて、抽出ポイントB1を左に曲がった抽出ポイントC1を検出し、抽出ポイントC1を、ユーザの目的地候補の一方として、ルートを解析する。また、そして、抽出ポイントA2として抽出された銀行の「角」である抽出ポイントB2は、走行履歴記録部12に記録されている走行履歴に含まれる部分であるので、ルート解析部22は、車両が抽出ポイントB2を走行していた時の進行方向を検出し、抽出ポイントB2の先の角、すなわち、抽出ポイントB2から進行方向の直近の角を左に曲がった抽出ポイントC2をユーザの目的地候補の他方と認識して、抽出ポイントC2へのルートを解析する。
That is, based on the contents registered in the relative word / phrase database 31, the route analysis unit 22 searches for “a bank in this” within a predetermined range based on the current position. As a result, the route analysis unit 22 extracts an extraction point A1 and an extraction point A2 which are "banks around this". Then, since the extraction point B1, which is the “corner” of the bank extracted as the extraction point A1, exists in the current traveling direction, the route analysis unit 22 uses the normal route analysis method to left the extraction point B1. The extraction point C1 is detected, and the route is analyzed with the extraction point C1 as one of the user's destination candidates. Also, since the extraction point B2 which is the “corner” of the bank extracted as the extraction point A2 is a portion included in the travel history recorded in the travel history recording unit 12, the route analysis unit 22 Detects the direction of travel when traveling through the extraction point B2, and the user moves the extraction point C2 to the left of the extraction point B2, that is, the left corner of the traveling direction from the extraction point B2 Recognizing the other as the candidate, the route to the extraction point C2 is analyzed.
なお、「このあたりの銀行の角を左」も、図6を用いて説明した場合と同様に、所定の地点からの進行方向だけが示されているが、抽出ポイントC1と抽出ポイントC2とのいずれがユーザの目的地であった場合においても、その方向に直進した先の進路に、現在位置から早く到着可能な地点が存在しないため、ルート解析部22は、抽出ポイントC1および抽出ポイントC2の2か所をユーザの目的地候補としたルート解析を実行する。
As in the case described with reference to FIG. 6, only the traveling direction from the predetermined point is shown for “left corner of the bank”, but the extraction point C1 and the extraction point C2 Even if either of the destinations is the user's destination, the route analysis unit 22 determines that the extraction point C1 and the extraction point C2 have no points on the route ahead ahead in the direction, because there is no point where they can arrive early from the current position. Route analysis is performed with two locations as user destination candidates.
ルート解析部22は、2つのルートの解析結果を、音声データ出力制御部23および表示制御部25に供給する。音声データ出力制御部23は、ルート解析部22から供給されたルート解析結果を音声データに変換し、スピーカー24からの音声データの出力を制御する。表示制御部25は、タッチパネル13を制御して、ルート解析部22から供給されたルート解析結果(図7において、ルート解析結果(1)およびルート解析結果(2)と示す)を表示出力させる。
The route analysis unit 22 supplies the analysis result of the two routes to the audio data output control unit 23 and the display control unit 25. The audio data output control unit 23 converts the route analysis result supplied from the route analysis unit 22 into audio data, and controls the output of the audio data from the speaker 24. The display control unit 25 controls the touch panel 13 to display and output the route analysis result (shown as route analysis result (1) and route analysis result (2) in FIG. 7) supplied from the route analysis unit 22.
このように、ナビゲーション装置1においては、「このあたり」という、通り過ぎた場所も進行方向に存在する場所も含む相対的な語句が含まれている場合においても、ユーザが意図する目的地へのルートを検索することが可能となる。また、ナビゲーション装置1においては、「このあたり」で示される範囲内で抽出された対象物が通り過ぎた場所に存在した場合においては、走行履歴記録部12に記録されている走行履歴を参照し、車両がある地点を走行していた時の進行方向を検出することができるようにしたので、ユーザが意図する目的地へのルートを検索することが可能となる。
As described above, in the navigation device 1, even when a relative phrase including “a passing place and a place existing in the traveling direction” is included, the route to the destination intended by the user. It becomes possible to search for Further, in the navigation device 1, when the object extracted in the range indicated by “in this case” is present at the passing place, the traveling history recorded in the traveling history recording unit 12 is referred to, Since it is possible to detect the traveling direction when the vehicle is traveling at a certain point, it becomes possible to search for a route to a destination intended by the user.
次に、例えば、ナビゲーション装置1を搭載する車両が図8のXに示される位置であり、車両の走行履歴が点線で示される状態である場合に、ユーザが、「近くの花屋の先の角を左」と発話した場合について説明する。
Next, for example, when the vehicle equipped with the navigation device 1 is at the position shown by X in FIG. 8 and the traveling history of the vehicle is in the state shown by the dotted line, the user The case of uttering "left" will be described.
ユーザの発話「近くの花屋の先の角を左」は、マイク16により集音され、音声データ取得部17により取得され、音声解析処理部18に供給される。音声解析処理部18は、供給された音声データに対する音声解析処理を行い、解析結果をあいまいさ判定部21に供給する。
The user's speech "the tip of the nearby flower shop is left" is collected by the microphone 16, acquired by the audio data acquisition unit 17, and supplied to the audio analysis processing unit 18. The voice analysis processing unit 18 performs voice analysis processing on the supplied voice data, and supplies the analysis result to the ambiguity determination unit 21.
あいまいさ判定部21は、相対的語句データベース31に登録されている相対的語句が含まれているか否かに基づいて、音声解析処理部18から供給された、ユーザの指令に対応する「近くの花屋の先の角を左」にあいまいさが含まれるか否かを判定する。「近くの花屋の先の角を左」には、「近く」「××の先」の相対的語句が含まれている。
The ambiguity determination unit 21 determines that “nearby” corresponding to the user's command supplied from the voice analysis processing unit 18 based on whether the relative phrase registered in the relative phrase database 31 is included. It is determined whether an ambiguity is included in "the left corner of the flower shop". The phrase “close to the tip of the nearby florist” includes relative phrases “near” and “next to xx”.
あいまいさ判定部21は、ユーザの指令に対応する情報とともに、あいまいさの判定結果をルート解析部22に供給する。ルート解析部22は、ユーザからの指令にあいまいさが含まれている場合、相対的語句データベース31に登録されている情報に基づいて、必要に応じて、走行履歴記録部12に記録されている走行履歴を参照し、ルート解析を実行する。
The ambiguity determination unit 21 supplies the determination result of the ambiguity to the route analysis unit 22 together with the information corresponding to the user's command. The route analysis unit 22 is recorded in the travel history recording unit 12 as needed based on the information registered in the relative word / phrase database 31 when the instruction from the user includes an ambiguity. Perform route analysis with reference to travel history.
すなわち、ルート解析部22は、相対的語句データベース31に登録されている内容に基づいて、「近くの花屋」を、現在位置を検索基準として、図2に示す半径Dメートル以内、たとえば半径500m圏内を検索条件とし、検索方向を現在位置周辺として検索する。または、ルート解析部22は、検索条件を現在地から「最寄りの1つまたは複数の候補地」としてもよく、最寄りの複数の候補地、たとえば3軒の候補をユーザに提示することを検索条件としてもよい。その結果、ルート解析部22は、「近くの花屋」である抽出ポイントA1および抽出ポイントA2を抽出する。そして、抽出ポイントA1として抽出された花屋は、走行履歴記録部12に記録されている走行履歴に含まれる部分である。そこで、ルート解析部22は、車両が抽出ポイントA1を走行していた時の進行方向を検出し、抽出ポイントA1の先の角、すなわち、抽出ポイントA1から進行方向の直近の角である抽出ポイントB1を左に曲がった抽出ポイントC1をユーザの目的地候補の一方と認識して、抽出ポイントC1へのルートを解析する。そして、抽出ポイントA2として抽出された花屋は、走行履歴記録部12に記録されている走行履歴に含まれないが、現在の位置周辺に存在する。すなわち、抽出ポイントA2として抽出された花屋を目標物としていた場合、ユーザは、ルートを間違えてしまっていた可能性がある。したがって、ルート解析部22は、車両が、走行履歴のいずれかの位置から最も早く抽出ポイントA2の前を走行していた場合(図8中、実線矢印で示される、A2が抽出ポイントであるときの仮ルート)における仮進行方向を検出し、抽出ポイントA2の先の角、すなわち、抽出ポイントA2から仮ルート仮進行方向の直近の角である抽出ポイントB2を左に曲がった抽出ポイントC2をユーザの目的地候補の他方と認識する。
That is, based on the contents registered in the relative word / phrase database 31, the route analysis unit 22 sets "a nearby flower shop" within a radius D meter shown in FIG. The search direction is searched around the current position with the search condition as the search condition. Alternatively, the route analysis unit 22 may set the search condition as “the one or more candidate locations closest to the current location” and present the user with a plurality of nearest candidate locations, for example, three candidates as the search criteria. It is also good. As a result, the route analysis unit 22 extracts an extraction point A1 and an extraction point A2 which are "near florists". The florist extracted as the extraction point A1 is a portion included in the travel history recorded in the travel history recording unit 12. Therefore, the route analysis unit 22 detects the traveling direction when the vehicle is traveling at the extraction point A1, and the extraction point that is the next corner of the extraction point A1, that is, the nearest corner from the extraction point A1 to the traveling direction The extraction point C1 with B1 turned to the left is recognized as one of the user's destination candidates, and the route to the extraction point C1 is analyzed. The florist extracted as the extraction point A2 is not included in the travel history recorded in the travel history recording unit 12, but exists around the current position. That is, when the florist extracted as the extraction point A2 is set as a target, the user may have mistaken the route. Therefore, when the vehicle travels the extraction point A2 the fastest from any position in the travel history (when A2 indicated by the solid line arrow in FIG. 8 is the extraction point), the route analysis unit 22 Of the provisional route), and the extraction point C2 is obtained by bending the extraction point B2, which is the closest corner of the provisional route provisional traveling direction from the extraction point A2, to the left. Recognize it as the other destination candidate of.
また、「近くの花屋の先の角を左」も、図6および図7を用いて説明した場合と同様に、所定の地点からの進行方向だけが示されている。抽出ポイントC1がユーザの目的地であった場合、その方向に直進した先の進路に、現在位置から早く到着可能な抽出ポイントは存在しない。しかしながら、抽出ポイントC2がユーザの目的地であった場合、その方向に直進した先の進路に、現在位置から早く到着可能な抽出ポイントD2が存在する。したがって、ルート解析部22は、抽出ポイントC1および抽出ポイントC2に加えて、抽出ポイントD2の3か所をユーザの目的地候補としたルート解析を実行する。
In addition, "the tip of the nearby florist on the left" also shows only the traveling direction from the predetermined point, as in the case described with reference to Figs. 6 and 7. If the extraction point C1 is the destination of the user, there is no extraction point that can arrive early from the current position on the path ahead in the direction going in that direction. However, if the extraction point C2 is the destination of the user, there is an extraction point D2 that can arrive early from the current position on the route ahead in the direction that the user travels. Therefore, in addition to the extraction point C1 and the extraction point C2, the route analysis unit 22 executes the route analysis in which three places of the extraction point D2 are candidates for the destination of the user.
ルート解析部22は、3つのルートの解析結果を、音声データ出力制御部23および表示制御部25に供給する。音声データ出力制御部23は、ルート解析部22から供給されたルート解析結果を音声データに変換し、スピーカー24からの音声データの出力を制御する。表示制御部25は、タッチパネル13を制御して、ルート解析部22から供給されたルート解析結果(図8において、ルート解析結果(1)およびルート解析結果(2)と示す)を表示出力させる。
The route analysis unit 22 supplies the analysis result of the three routes to the audio data output control unit 23 and the display control unit 25. The audio data output control unit 23 converts the route analysis result supplied from the route analysis unit 22 into audio data, and controls the output of the audio data from the speaker 24. The display control unit 25 controls the touch panel 13 to display and output the route analysis result (shown as route analysis result (1) and route analysis result (2) in FIG. 8) supplied from the route analysis unit 22.
このように、ナビゲーション装置1においては、「このあたり」という相対的な語句に対応する範囲内に、現在の進行方向の先ではなく、また、走行履歴に含まれていない抽出ポイントを検索した場合、走行履歴記録部12に記録されている走行履歴を参照し、車両が、間違わずに目標物に向かって走行していた場合の仮進行方向を検出することができるようにしたので、ユーザがルートを間違えて走行していた場合においても、ユーザが意図する目的地へのルートを検索することが可能となる。
As described above, in the navigation device 1, when the extraction point which is not the destination of the current traveling direction and is not included in the travel history is searched within the range corresponding to the relative phrase “this part”. Since the user can detect the temporary traveling direction when the vehicle is traveling toward the target without mistake by referring to the traveling history recorded in the traveling history recording unit 12, the user can Even when traveling by mistake, it is possible to search for a route to a destination intended by the user.
次に、例えば、ナビゲーション装置1を搭載する車両が図9のXに示される位置であり、車両の走行履歴が点線で示される状態である場合に、ユーザが、「さっきの交差点を左」と発話した場合について説明する。
Next, for example, when the vehicle equipped with the navigation device 1 is at the position indicated by X in FIG. 9 and the travel history of the vehicle is indicated by a dotted line, the user says “left at the previous intersection”. The case of speaking will be described.
ユーザの発話「さっきの交差点を左」は、マイク16により集音され、音声データ取得部17により取得され、音声解析処理部18に供給される。音声解析処理部18は、供給された音声データに対する音声解析処理を行い、解析結果をあいまいさ判定部21に供給する。
The speech of the user “left at the previous intersection” is collected by the microphone 16, acquired by the audio data acquisition unit 17, and supplied to the audio analysis processing unit 18. The voice analysis processing unit 18 performs voice analysis processing on the supplied voice data, and supplies the analysis result to the ambiguity determination unit 21.
あいまいさ判定部21は、相対的語句データベース31に登録されている相対的語句が含まれているか否かに基づいて、音声解析処理部18から供給された、ユーザの指令に対応する「さっきの交差点を左」にあいまいさが含まれるか否かを判定する。「さっきの交差点を左」には、「さっき」の相対的語句が含まれている。
The ambiguity determination unit 21 responds to the user's command supplied from the speech analysis processing unit 18 based on whether or not the relative phrase registered in the relative phrase database 31 is included. It is determined whether an ambiguity is included on the left of the intersection. The "left at the intersection" contains the relative phrase "before".
あいまいさ判定部21は、ユーザの指令に対応する情報とともに、あいまいさの判定結果をルート解析部22に供給する。ルート解析部22は、ユーザからの指令にあいまいさが含まれている場合、相対的語句データベース31に登録されている情報に基づいて、必要に応じて、走行履歴記録部12に記録されている走行履歴を参照し、ルート解析を実行する。
The ambiguity determination unit 21 supplies the determination result of the ambiguity to the route analysis unit 22 together with the information corresponding to the user's command. The route analysis unit 22 is recorded in the travel history recording unit 12 as needed based on the information registered in the relative word / phrase database 31 when the instruction from the user includes an ambiguity. Perform route analysis with reference to travel history.
ルート解析部22は、走行履歴記録部12に記録されている走行履歴を参照し、現在位置から所定範囲内に、「さっきの交差点」である抽出ポイントA1およびA2を抽出する。図3を用いて説明した「さっきまがった交差点」の場合と異なり、「さっきの交差点」は、所定範囲内に複数存在する。
The route analysis unit 22 refers to the travel history recorded in the travel history recording unit 12 and extracts the extraction points A1 and A2 that are “the previous intersection” within a predetermined range from the current position. Unlike in the case of the “pre-crossed intersection” described with reference to FIG. 3, there are a plurality of “pre-intersections” within a predetermined range.
そして、ルート解析部22は、走行履歴記録部12に記録されている走行履歴を参照し、車両が抽出ポイントA1および抽出ポイントA2に示される交差点に進入した場合の進行方向を検出し、抽出ポイントA1および抽出ポイントA2のそれぞれにおいて、進行方向から左折した場合の抽出ポイントB1および抽出ポイントB2をそれぞれユーザの目的地と認識してルートを解析する。
Then, the route analysis unit 22 refers to the travel history recorded in the travel history recording unit 12 and detects the traveling direction when the vehicle enters the intersection indicated by the extraction point A1 and the extraction point A2, and the extraction point In each of A1 and extraction point A2, the extraction point B1 and extraction point B2 in the case of turning left from the traveling direction are respectively recognized as the destination of the user, and the route is analyzed.
なお、「さっきの交差点を左」も、図6~図8を用いて説明した場合と同様に、所定の地点からの進行方向だけが示されているが、抽出ポイントB1と抽出ポイントB2とのいずれがユーザの目的地であった場合においても、その方向に直進した先の進路に、現在位置から早く到着可能な抽出ポイントが存在しないため、ルート解析部22は、抽出ポイントB1および抽出ポイントB2の2か所をユーザの目的地候補としたルート解析を実行する。
In the same manner as described with reference to FIGS. 6 to 8, “left at the previous intersection” only shows the traveling direction from a predetermined point, but the extraction point B1 and the extraction point B2 Even if either of the destinations is the user's destination, the route analysis unit 22 extracts the extraction point B1 and the extraction point B2 because there is no extraction point that can arrive early from the current position on the route ahead in the direction. The route analysis is performed with two points as the destination candidate of the user.
ルート解析部22は、ルートの解析結果を、音声データ出力制御部23および表示制御部25に供給する。音声データ出力制御部23は、ルート解析部22から供給されたルート解析結果を音声データに変換し、スピーカー24からの音声データの出力を制御する。表示制御部25は、タッチパネル13を制御して、ルート解析部22から供給されたルート解析結果(図9において、ルート解析結果(1)およびルート解析結果(2)と示す)を表示出力させる。
The route analysis unit 22 supplies the analysis result of the route to the audio data output control unit 23 and the display control unit 25. The audio data output control unit 23 converts the route analysis result supplied from the route analysis unit 22 into audio data, and controls the output of the audio data from the speaker 24. The display control unit 25 controls the touch panel 13 to display and output the route analysis result (shown as route analysis result (1) and route analysis result (2) in FIG. 9) supplied from the route analysis unit 22.
このように、ナビゲーション装置1においては、「さっきの角」を所定範囲内で複数抽出可能とし、走行履歴記録部12に記録されている走行履歴を参照し、車両がある地点を走行していた時の進行方向をそれぞれ検出することができるようにしたので、「さっき」というあいまいさを含む相対的な語句が含まれている場合においても、ユーザが意図する目的地へのルートを検索することが可能となる。
As described above, in the navigation device 1, a plurality of “first corner” can be extracted within a predetermined range, and the traveling history recorded in the traveling history recording unit 12 is referred to, and the vehicle travels at a point Since it is possible to detect the direction of travel of each hour, search for a route to the destination intended by the user, even when the relative phrase including the ambiguity "Saki" is included. Is possible.
次に、図10のフローチャートを参照し、ナビゲーション装置1が実行するナビゲーション処理について説明する。
Next, navigation processing performed by the navigation device 1 will be described with reference to the flowchart in FIG.
ステップS1において、現在位置情報取得部11は、車両の現在位置情報を取得し、走行履歴記録部12およびルート解析部22に供給する。走行履歴記録部12は、地図データベース19に登録されている地図を参照し、現在位置情報取得部11から供給された車両の現在位置情報に基づいて、車両の走行履歴を記録する。
In step S <b> 1, the current position information acquisition unit 11 acquires current position information of the vehicle and supplies it to the travel history recording unit 12 and the route analysis unit 22. The traveling history recording unit 12 refers to the map registered in the map database 19 and records the traveling history of the vehicle based on the current position information of the vehicle supplied from the current position information acquiring unit 11.
ステップS2において、あいまいさ判定部21は、入力制御部15または音声解析処理部18から供給される情報に基づいて、ユーザから、ナビゲーションの指示を受けたか否かを判断する。ステップS2において、ナビゲーションの指示を受けていないと判断された場合、処理はステップS1に戻る。
In step S2, based on the information supplied from the input control unit 15 or the voice analysis processing unit 18, the ambiguity determination unit 21 determines whether or not a navigation instruction has been received from the user. If it is determined in step S2 that the navigation instruction has not been received, the process returns to step S1.
ステップS2において、ナビゲーションの指示を受けたと判断された場合、ステップS3において、あいまいさ判定部21は、相対的語句データベース31を参照して、ユーザからのナビゲーションの指令には、あいまいさが含まれるか否かを判断する。あいまいさ判定部21は、ユーザの指令に対応する情報とともに、あいまいさの判定結果をルート解析部22に供給する。
If it is determined in step S2 that the navigation instruction has been received, the ambiguity determination unit 21 refers to the relative word / phrase database 31 in step S3 and the navigation instruction from the user includes the ambiguity. Determine if it is or not. The ambiguity determination unit 21 supplies the determination result of the ambiguity to the route analysis unit 22 together with the information corresponding to the user's command.
ステップS2において、あいまいさが含まれないと判断された場合、ステップS4において、ルート解析部22は、通常のルート解析処理を実行し、処理は、ステップS6に進む。
When it is determined in step S2 that no ambiguity is included, in step S4, the route analysis unit 22 executes a normal route analysis process, and the process proceeds to step S6.
ステップS2において、あいまいさが含まれると判断された場合、ステップS5において、図11および図12を用いて後述する相対的語句対応ルート解析処理が実行され、処理は、ステップS6に進む。
If it is determined in step S2 that an ambiguity is included, a relative phrase corresponding route analysis process described later with reference to FIGS. 11 and 12 is performed in step S5, and the process proceeds to step S6.
ステップS6において、ルート解析部22は、ルートの解析結果を、音声データ出力制御部23および表示制御部25に供給する。音声データ出力制御部23は、ルート解析部22から供給されたルート解析結果を音声データに変換し、スピーカー24からの音声データの出力を制御する。表示制御部25は、タッチパネル13を制御して、ルート解析部22から供給されたルート解析結果を表示出力させ、処理を終了する。
In step S6, the route analysis unit 22 supplies the analysis result of the route to the audio data output control unit 23 and the display control unit 25. The audio data output control unit 23 converts the route analysis result supplied from the route analysis unit 22 into audio data, and controls the output of the audio data from the speaker 24. The display control unit 25 controls the touch panel 13 to display and output the route analysis result supplied from the route analysis unit 22, and ends the process.
次に、図11および図12のフローチャートを参照して、図10のステップS5において実行される相対的語句対応ルート解析処理について説明する。
Next, the relative phrase corresponding route analysis process executed in step S5 of FIG. 10 will be described with reference to the flowcharts of FIGS. 11 and 12.
ステップS21において、ルート解析部22は、あいまいさ判定部21から供給された、ユーザの指令に対応する情報から、抽出ポイントを決定可能な語句群を抽出する。例えば、ユーザの指令に対応する情報が、図4を用いて説明した「次のコンビニの角を右折したあたりのスーパー」であった場合、ルート解析部22は、まず、「次のコンビニ」を抽出する。例えば、ユーザの指令に対応する情報が、図5を用いて説明した「通り過ぎたコンビニの手前の角まで戻る」であった場合、ルート解析部22は、まず、「通り過ぎたコンビニ」を抽出する。
In step S21, the route analysis unit 22 extracts, from the information corresponding to the user's command supplied from the ambiguity determination unit 21, the word / phrase group capable of determining the extraction point. For example, if the information corresponding to the user's command is "super around the corner of the next convenience store" described with reference to FIG. 4, the route analysis unit 22 first selects "next convenience store". Extract. For example, if the information corresponding to the user's command is "return to the corner before the passing convenience store" described using FIG. 5, the route analysis unit 22 first extracts "the passing convenience store". .
ステップS22において、ルート解析部22は、相対的語句データベース31を参照して、ステップS21において抽出した語句群には、相対的語句が含まれるか否かを判断する。例えば、ユーザの指令に対応する情報が、図4を用いて説明した「次のコンビニの角を右折したあたりのスーパー」であった場合、最初に抽出された「次のコンビニ」には、相対的語句が含まれておらず、従来の方法にて抽出ポイントの検索が可能な語句である。例えば、ユーザの指令に対応する情報が、図5を用いて説明した「通り過ぎたコンビニの手前の角まで戻る」であった場合、最初に抽出された「通り過ぎたコンビニ」には、相対的語句データベース31に登録されている相対的語句が含まれている。
In step S22, the route analysis unit 22 refers to the relative word / phrase database 31 and determines whether the word / phrase group extracted in step S21 includes a relative word / phrase. For example, in the case where the information corresponding to the user's command is "super around the corner of the next convenience store" described with reference to FIG. 4, relative to the "next convenience store" extracted first It is a word that does not contain the target word and can search for the extraction point by the conventional method. For example, if the information corresponding to the user's command is “return to the corner before the passing convenience store” described with reference to FIG. The relative words registered in the database 31 are included.
ステップS22において、相対的語句が含まれていないと判断された場合、ステップS23において、ルート解析部22は、地図データベース19を参照して、抽出された語句に対応する抽出ポイントを地図から検出し、処理は、後述するステップS30に進む。
If it is determined in step S22 that a relative phrase is not included, the route analysis unit 22 detects an extraction point corresponding to the extracted phrase from the map with reference to the map database 19 in step S23. The process proceeds to step S30 described later.
ステップS22において、相対的語句が含まれていないと判断された場合、ステップS24において、ルート解析部22は、相対的語句データベース31を参照し、対応する語句を検出する。
If it is determined in step S22 that the relative phrase is not included, in step S24, the route analysis unit 22 refers to the relative phrase database 31 and detects the corresponding phrase.
ステップS25において、ルート解析部22は、相対的語句データベース31から、抽出された語句に対応する、検索基準、検索方向、検索範囲を抽出する。
In step S25, the route analysis unit 22 extracts, from the relative word / phrase database 31, the search criteria, the search direction, and the search range corresponding to the extracted word / phrase.
ステップS26において、ルート解析部22は、抽出ポイントの検索には、走行履歴が利用されるか否かを判断する。
In step S26, the route analysis unit 22 determines whether the travel history is used to search for the extraction point.
ステップS26において、走行履歴が利用されないと判断された場合、ステップS27において、ルート解析部22は、抽出された語句に対応する検索基準、検索方向、検索範囲に基づいて、抽出ポイントを地図から検出し、後述するステップS30に進む。
In step S26, when it is determined that the travel history is not used, in step S27, the route analysis unit 22 detects the extraction point from the map based on the search criteria, the search direction, and the search range corresponding to the extracted word. Then, the process proceeds to step S30 described later.
ステップS26において、走行履歴が利用されると判断された場合、ステップS28において、ルート解析部22は、走行履歴記録部12に記録されている走行履歴を読み込む。
If it is determined in step S26 that the travel history is to be used, the route analysis unit 22 reads the travel history recorded in the travel history recording unit 12 in step S28.
ステップS29において、ルート解析部22は、抽出された語句に対応する検索基準、検索方向、検索範囲、および、走行履歴に基づいて、抽出ポイントを地図から検出する
In step S29, the route analysis unit 22 detects an extraction point from the map based on the search criteria, the search direction, the search range, and the travel history corresponding to the extracted word / phrase.
ステップS23、ステップS27、または、ステップS29の処理の終了後、ステップS30において、ルート解析部22は、ステップS23、ステップS27、または、ステップS29の処理において求められた抽出ポイントには、複数の候補があるか否かを判断する。ステップS30において、複数の候補がないと判断された場合、処理は、後述するステップS32に進む。
After the process of step S23, step S27, or step S29 is completed, in step S30, the route analysis unit 22 selects a plurality of candidates for the extraction points obtained in the process of step S23, step S27, or step S29. Determine if there is. If it is determined in step S30 that there is not a plurality of candidates, the process proceeds to step S32 described later.
ステップS30において、複数の候補があると判断された場合、ステップS31において、ルート解析部22は、複数候補すべてに対して抽出ポイントの検出が終了したか否かを判断する。ステップS31において、複数候補すべてに対して抽出ポイントの検出が終了していないと判断された場合、処理は、ステップS22に戻り、それ以降の処理が繰り返される。
If it is determined in step S30 that there are a plurality of candidates, in step S31, the route analysis unit 22 determines whether or not the detection of the extraction point has ended for all the plurality of candidates. If it is determined in step S31 that the extraction point detection has not been completed for all of the plurality of candidates, the process returns to step S22, and the subsequent processes are repeated.
ステップS30において、複数の候補がないと判断された場合、または、ステップS31において、複数候補すべてに対して抽出ポイントの検出が終了したと判断された場合、ステップS32において、ルート解析部22は、ユーザの指令に対応する情報に含まれる語句の全てに対して処理が終了したか否かを判断する。ステップS32において、語句の全てに対して処理が終了していないと判断された場合、処理は、ステップS21に戻り、次の語句群が抽出されて、それ以降の処理が繰り返される。
If it is determined in step S30 that there is not a plurality of candidates, or if it is determined in step S31 that the extraction point detection has ended for all of the plurality of candidates, the route analysis unit 22 determines in step S32 It is determined whether the processing has been completed for all of the terms included in the information corresponding to the user's command. If it is determined in step S32 that the process has not been completed for all of the words, the process returns to step S21, the next word group is extracted, and the subsequent processes are repeated.
ステップS32において、語句の全てに対して処理が終了したと判断された場合、ステップS33において、ルート解析部22は、最後の抽出ポイントまでのルート解析処理を実行する。
If it is determined in step S32 that the process has been completed for all of the words and / or phrases, in step S33, the route analysis unit 22 executes route analysis processing up to the last extraction point.
ステップS34において、ルート解析部22は、例えば、図6または図8を用いて説明した場合のように、最後の抽出ポイントから進行方向に進んだ場合、現在位置から早く到着可能な個所が存在するか、すなわち、適したルートが存在するか否かを判断する。ステップS34において、最後の抽出ポイントから進行方向に進んだ場合にも適したルートが存在しないと判断された場合、処理は、図10のステップS6に進む。
In step S34, when the route analysis unit 22 proceeds in the direction of travel from the last extraction point, as in the case described with reference to FIG. Whether or not there is a suitable route. If it is determined in step S34 that a suitable route does not exist even in the case of proceeding in the traveling direction from the last extraction point, the process proceeds to step S6 in FIG.
ステップS34において、最後の抽出ポイントから進行方向に進んだ場合に適したルートが存在すると判断された場合、ステップS35において、ルート解析部22は、最後の抽出ポイントから進行方向に進んだ場合のルート解析処理を実行し、処理は、図10のステップS6に進む。
If it is determined in step S34 that there is a route suitable for the case of proceeding in the traveling direction from the last extraction point, in step S35, the route analysis unit 22 proceeds in the traveling direction from the last extraction point The analysis process is performed, and the process proceeds to step S6 in FIG.
このような処理により、ナビゲーション装置1においては、相対的な語句に対応してルート検索することができるので、ユーザが、経路を間違えたり、経路の記憶があいまいであったり、通り過ぎたところにもう一度戻りたい場合などであっても、ユーザが目的とする進路を推定して、ルート検索を実行することができる。
By such processing, in the navigation device 1, since the route search can be performed corresponding to the relative word / phrase, the user makes a mistake in the route, the memory of the route is ambiguous, and the passing again Even if the user wants to go back, it is possible to estimate the route for which the user is aiming and perform route search.

The computer program may be a computer program that performs processing.
また、本発明の実施の形態は、上述した実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲において種々の変更が可能である。
Further, the embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
例えば、ナビゲーション装置1において、図2に示した相対的語句データベース31を編集する機能を備えてもよい。図2の相対的語句データベース31では、相対的語句「さっき」について検索条件をAメートルとしているが、この条件はユーザによって感覚が異なる場合がある。相対的語句データベース31において、語句ごとに設定される検索条件を編集可能とすることにより、相対的語句データベース31をユーザごとに最適化することができる。また、相対的語句データベース31に、新たな語句の登録を可能とすることで、方言や外国語に対応した相対的語句による行き先の指定を実現することが可能となる。
For example, the navigation device 1 may have a function of editing the relative word / phrase database 31 shown in FIG. In the relative word / phrase database 31 of FIG. 2, the search condition is set to A meter for the relative word / phrase “Saki”, but the feeling may differ depending on the user. In the relative word / phrase database 31, by making search conditions set for each word / phrase editable, the relative word / phrase database 31 can be optimized for each user. Further, by enabling registration of new words in the relative word / phrase database 31, it becomes possible to realize designation of destinations by relative words / words corresponding to dialects or foreign languages.
また、ナビゲーション装置1においては、相対的語句データベース31を、学習によりユーザごとに最適化する機能を備えてもよい。例えば、「さっきの交差点」という語句に対して検索されてユーザに案内された交差点が、ユーザの意図と異なった場合、ユーザは、検索結果を取り消したり、検索をやり直すなどの操作を行う。ナビゲーション装置1は、ユーザにより、検索結果が取り消されたり、検索がやり直されるなどの操作入力を受けた場合、語句「さっき」に対応する検索条件がユーザ意図と異なることを認識する。このような場合、ナビゲーション装置1においては、相対的語句データベース31に登録されている検索条件を変更することで、相対的語句データベース31をユーザごとに最適化することが可能となる。
In addition, the navigation device 1 may have a function of optimizing the relative word / phrase database 31 for each user by learning. For example, when the intersection searched for the word “the intersection of the previous time” and guided to the user is different from the user's intention, the user performs an operation such as canceling the search result or performing the search again. The navigation apparatus 1 recognizes that the search condition corresponding to the phrase “Saki” is different from the user's intention when the user receives an operation input such as cancellation of the search result or re-execution of the search. In such a case, in the navigation device 1, the relative phrase database 31 can be optimized for each user by changing the search condition registered in the relative phrase database 31.
また、相対的語句データベース31においては、登録語句と施設ジャンルをひも付けすることなどにより、「さっきの交差点」であれば現在地から30m程度、「さっきのコンビニ」なら現在地から100m程度など、目的とする施設によって語句ごとの検索条件を変更するものとしてもよい。また、この場合、登録語句と施設ジャンルをひも付けするのではなく、施設ジャンルごとに相対的語句データベース31を備えるものとしてもよい。
In the relative word / phrase database 31, by linking the registered word / phrase with the facility genre, it is about 30 m from the current location in the case of the “first intersection” and about 100 m from the current location in the “first convenience store”. The search condition for each word may be changed depending on the facility to be used. Further, in this case, the relative word / phrase database 31 may be provided for each of the facility genres, instead of linking the registered words and the facility genres.
