推奨操作定義部4は、現在位置情報と、経路情報と、推奨操作情報の内容と、走行予定道路の状況を予測した情報とに基づいて、推奨操作情報の出力地点を定義する。
推奨操作定義部4は、例えば、車両が目的地を設定せずに走行を開始した場合、走行開始後100m地点を、「AB遊園地を目的地に設定する」との推奨操作情報の内容が出力される出力地点として定義する。
また、推奨操作定義部4は、例えば、車両が目的地を設定して走行している場合、目的地の手前2km地点を、「目的地周辺の駐車場を経由地に設定する」との推奨操作情報の内容が出力される出力地点として定義する。
また、推奨操作定義部4は、例えば、車両が高速道路を走行している場合、サービスエリアの3km手前地点を、「次のサービスエリアの情報を表示する」との推奨操作情報の内容が出力される出力地点として定義する。
また、推奨操作定義部4は、例えば、車両が高速道路を降りた直後の場合、料金所出口から300m地点で「道の駅を経由地に設定する」との推奨操作情報の内容が出力される出力地点として定義する。
図3Aおよび図3Bは、実施の形態1に係る情報提供装置100の推奨操作定義部4が参照するデータベースの一例を示す図である。
図3Aおよび図3Bで示したデータベースは、出力地点および各推奨操作内容の出力尤度で構成され、2つの推奨操作内容「目的地を設定する」および「地図を拡大する」の出力尤度の例を示している。出力尤度は、例えば0から100の数字で表す。
図3Aは、出力尤度を予め設定した場合のデータベースを示している。
推奨操作定義部4は、図3Aのデータベースを参照し、各出力地点において、例えば出力尤度の上位N個の推奨操作内容を、その地点での推奨操作内容として定義する。
例えば、過去の操作履歴において、「目的地を設定する」との操作が「自宅から300m以内」よりも「自宅から300m以上1km以内」で行われる頻度が高い場合には、推奨操作内容「目的地を設定する」の出力地点が「自宅から300m以内」である場合の出力尤度は「90」から「85」に減少する。一方、推奨操作内容「目的地を設定する」の出力地点が「自宅から300m以上1km以内」である場合の出力尤度は「50」から「55」に増加する。
推奨操作定義部4は、図3Bのデータベースを参照し、各出力地点において、例えば出力尤度の上位N個の推奨操作内容を、その地点での推奨操作内容として定義する。
複雑度判定部5は、第1の経路状況取得部3が取得した移動予定経路の経路状況を予測した情報のうち、推奨操作定義部4が定義した推奨操作情報の出力地点を含む区間の静的な経路状況を示した情報が示すパラメータのパラメータ数およびパラメータ値に基づいて、当該出力地点を含む区間の複雑度を求める。
上述した、静的な経路状況とは、時間の経過に伴ってほぼ変化しない経路の状況であり、例えば、車線数、道路種別、道路形態、道路幅員、右左折地点、交差点、分岐点、合流地点等の状況である。複雑度判定部5は、これらの静的な経路状況を示した情報のパラメータ数および各パラメータのパラメータ値に基づいて、定義された推奨操作情報の出力地点を含む区間の経路状況が複雑であるかを複雑度で表す。
複雑度判定部5は、各パラメータのパラメータ値が大きいほど、複雑度を高く設定する。
一方、複雑度が閾値以上である場合に、複雑度判定部5は、推奨操作定義部4が定義した推奨操作情報の出力地点を含まない他の区間の複雑度を求める。複雑度判定部5は、他の区間の複雑度が予め設定された閾値以上であるか判定を行う。複雑度判定部5は、推奨操作定義部4が定義した推奨操作情報の内容および出力地点と、判定結果とを、出力する。
複雑度判定部5は、例えば、図4に示す予め定義されたテーブルを参照して複雑度を求める。
図4で示したテーブルにおいて、「経路状況数」は推奨操作情報の出力地点を含む区間の静的な経路状況として取得した情報の数である。例えば、区間の車線数のみの情報を取得した場合には「1」となり、区間の車線数、道路種別、右左折地点の情報を取得した場合には「3」となる。
テーブルの「パラメータ値」は、取得した区間の静的な経路状況を示した情報のパラメータ値の和である。テーブルの「複雑度」は、各パラメータ値の和に対応して設定すべき複雑度の値である。
複雑度「1」は、車両がスムーズに走行できる経路状況を示す。例えば、信号の少ない郊外の県道、片側2車線の国道等、スムーズに走行できると想定される経路状況等である。
複雑度「2」は、普段よりも周囲の確認が必要な経路状況を示す。例えば、踏切、料金所、など、普段より比較的速度を落として運転する必要のある経路状況等である。
複雑度「3」は、普段よりも周囲の確認が必要な経路状況を示す、例えば、交差点の右左折時、高速道路の合流地点等である。
例えば、推奨操作定義部4が定義した推奨操作情報の出力地点を含む区間の静的な経路状況を示した情報のパラメータのパラメータ数が「3」である、当該パラメータのパラメータ値の和が「5」であった場合に、複雑度判定部5は複雑度を「2」と設定する。
図5は、実施の形態1による情報提供装置100の動作を示すフローチャートである。
現在位置情報取得部1は、車両の現在位置情報を取得する(ステップST101)。経路情報取得部2は、車両に設定された経路情報を取得する(ステップST102)。第1の経路状況取得部3は、ステップST101で取得された車両の現在位置情報およびステップST102で取得された経路情報から、車両の移動予定経路を設定し、設定した移動予定経路の経路状況を予測した情報を取得する(ステップST103)。推奨操作定義部4は、ステップST101で取得された車両の現在位置情報、ステップST102で取得された経路情報、およびステップST103で取得された移動予定経路の経路状況から、運転者に推奨する推奨操作情報の内容および出力地点を定義する(ステップST104)。
図6は、実施の形態1に係る情報提供装置100の複雑度判定部5および推奨操作決定部6の動作を示すフローチャートである。
ステップST104として推奨操作定義部4が推奨操作情報の内容および出力地点を定義すると、複雑度判定部5は、移動予定経路から、推奨操作情報の出力地点を含む区間を特定する(ステップST121)。複雑度判定部5は、第1の経路状況取得部3が取得した移動予定経路の経路状況を予測した情報から、ステップST121で特定した区間の静的な経路状況を取得し、取得した静的な経路情報が示すパラメータのパラメータ数およびパラメータ値に基づいて、特定した区間の複雑度を求める(ステップST122)。
図7は、実施の形態1に係る情報提供装置100が情報を提供する車両の走行を例示した図である。
図7では、車両Xが現在位置である地点Pに位置し、目的地Yが地点Rに設定されている。図7において、地点Qは、車両の現在位置である地点Pから所定の距離離れた地点であり、当該地点Qから地点Rまでの間に設定された経路が、移動予定経路Sである。
この実施の形態2では、移動予定経路の全ての区間において、複雑度が閾値以上であった場合について説明する。
図8は、この発明の実施の形態2に係る情報提供装置100aの構成を示すブロック図である。
実施の形態2に係る情報提供装置100aは、図1に示した実施の形態1の情報提供装置100に対して第2の経路状況取得部8が追加され、複雑度判定部5および推奨操作決定部6が複雑度判定部5aおよび推奨操作決定部6aに変更されている。図8において図1と同一または相当する部分は、同一の符号を付し説明を省略する。
第2の経路状況取得部8は、例えば移動体が車両である場合、車載機器、車載センサ、地図データ、道路交通情報、VICS情報、DSRCにより取得した情報、の少なくとも一つから移動経路状況監視情報を取得する。
複雑度判定部5aは、移動予定経路の全ての区間について経路状況が複雑であると判定した場合に、移動経路の状況を監視した情報のうち、静的な経路状況を監視した情報を用いて、車両が移動経路を走行中に、運転者が、推奨操作定義部4によって定義された内容の操作を実行すると複雑であるか、すなわち移動経路の経路状況が複雑であるかを判定する。複雑度判定部5aは、移動経路の判定結果を、移動経路の複雑度として、レベル1、レベル2、レベル3等といった、複雑度を段階的に示したレベルで示す。なお、複雑度判定部5aは、レベルで示す以外の方法で複雑度を示してもよい。
一方、操作結果を目視で確認する必要がある内容とは、例えば「縮尺を変更する」、または「コンビニを目的地に設定する」等である。推奨操作決定部6aは、操作結果を画面上等で目視で確認する必要がある操作を、例えば種別bの内容に分類する。
推奨操作決定部6aは、内容の分類結果を参照し、種別aおよび種別bの内容が含まれる場合、当該種別bの内容を削除し、種別aの内容のみを有する推奨操作情報に変更する。
図9は、実施の形態2に係る情報提供装置100aの動作を示すフローチャートである。図9において、図5で示した実施の形態1のフローチャート同一のステップには同一の符号を付し、説明を省略する。
ステップST101およびステップST102の処理が行われると、第2の経路状況取得部8は、ステップST101で取得される車両の現在位置情報およびステップST102で取得された経路情報から、車両の移動経路を設定し、当該移動経路の状況を監視した情報を取得する(ステップST201)。その後、ステップST103からステップST106の処理を行う。次に、複雑度判定部5aはステップST104で定義された推奨操作情報の出力地点を含まない他の区間について複雑度を取得し、当該複雑度が閾値未満である区間が存在するか判定を行う(ステップST107a)。複雑度が閾値未満である区間が存在する場合(ステップST107a;YES)、ステップST108以降の処理を行う。
図10は、実施の形態2に係る情報提供装置100aの推奨操作決定部6aの動作を示すフローチャートである。
推奨操作決定部6aは、ステップST203で出力された判定結果に基づいて、推奨操作情報の内容を、操作結果を目視で確認する必要がある種別と、操作結果を目視で確認する必要がない種別とに分類する(ステップST211)。推奨操作決定部6aは、ステップST211で分類した種別を参照し、内容に操作結果を目視で確認する必要がない種別の操作が含まれるか判定を行う(ステップST212)。
第2の経路状況取得部8は、ステップST201として、移動経路の状況を監視した情報を取得する。第1の経路状況取得部3は、ステップST103として、移動予定経路の経路状況を予測した情報を取得する。推奨操作定義部4が、ステップST104として、例えば「AVを切り替える」、「音量を調整する」および「案内地点を表示する」の3つの操作を含む内容を有する推奨操作情報を定義する。次に、複雑度判定部5aは、ステップST105として推奨操作情報の出力地点を含む区間の複雑度「3」であり、閾値以上であると判定する(YESと判定する)。また、複雑度判定部5aは、ステップST106として移動予定経路の他の全ての区間の複雑度が「3」であり、閾値未満でないと判定する(NOと判定する)。
図11A、図11Bは、推奨操作定義部4が定義した同一の推奨操作情報に対して処理を行った場合の表示画面例を示している。図11Aは、情報提供装置100が、以下の条件を満たすと判定した場合に提供される推奨操作情報に基づいた表示画面例である。
・移動予定経路に、複雑度が、予め設定された閾値未満の区間がある
・推奨操作定義部4が種別aの内容および種別bの内容の推奨操作情報を定義
上述した2つの条件を満たす場合、図11Aに示すように、種別aの内容の推奨操作情報である「2.ラジオに切り替える」と、種別bの内容の推奨操作情報である「1.コンビニを目的地に設定する」および「3.縮尺を大きくする」とが表示される。
・移動予定経路に、複雑度が、予め設定された閾値未満の区間がない
・移動経路の複雑度が、予め設定された閾値未満である
・推奨操作定義部4が種別aの内容および種別bの内容の推奨操作情報を定義
・推奨操作決定部6が種別bのみの内容の推奨操作情報に変更
上述した4つの条件を満たす場合、図11Bに示すように種別bの内容の推奨操作情報である「1.ラジオに切り替える」と、「2.音量を小さくする」とが表示される。図11Bの表示画面例では、種別bの内容の推奨操作情報である「コンビニを目的地に設定する」および「縮尺を大きくする」が削除され、推奨操作定義部4が4番目に定義していた推奨操作情報である「音量を小さくする」が繰り上がり、2番目に表示される。
なお、画面上に表示される推奨操作情報の数は、画面の大きさなどに基づいて適宜設定されるものとする。
この実施の形態3では、車両が推奨操作情報の出力地点を含む移動経路を走行している際に、当該移動経路の難易度を判定する構成について説明する。
図12は、実施の形態3に係る情報提供装置100bの構成を示すブロック図である。 実施の形態3に係る情報提供装置100bは、図8に示した実施の形態2の情報提供装置100aに対して難易度判定部9が追加され、推奨操作決定部6aが推奨操作決定部6bに変更されている。図12において図8と同一または相当する部分は、同一の符号を付し説明を省略する。
図13で示したテーブルにおいて「経路状況数」は走行区間の動的な状況として取得した情報の数である。テーブルの項目「パラメータ値」は、取得した走行区間の動的な状況を監視した情報のパラメータ値の和である。テーブルの項目「難易度」は、各パラメータ値の和に対応して設定すべき難易度の値である。
図13では、難易度判定部9が、3段階の基準に当てはまるパラメータ値を難易度の判定材料とした場合を例に示している。難易度判定部9は、例えば、通行人と自車の距離が近い状態、自転車が自車に近づいている状態など、人や軽車両が自車に近づいている状況を示すパラメータを有する場合、難易度「1」と設定する。また、難易度判定部9は、例えば、前方車両が速度を落として車線変更をしている状態、二輪車が自車を追い抜こうとしている状態等、周辺車両が自車に近づいている状況を示すパラメータを有する場合、難易度「2」と設定する。また、難易度判定部9は、例えば、豪雨時、凍結時など、片手をハンドルから手放して操作を行うと非常に複雑度が増す状況を示すパラメータを有する場合、難易度「3」と設定する。
推奨操作決定部6bは、例えば、難易度判定部9から入力された難易度が「2」以上である場合、推奨操作情報の出力様態を決定する。推奨操作決定部6bは、例えば、推奨操作決定部6bは、表示文字の大きさを大きくする、表示文字の色を変更する、表示文字のフォントを変更する、音声出力の音声を変更する、などの変更を行う。
推奨操作決定部6bは、例えば、難易度判定部9から入力された難易度が「2」以上の場合、推奨操作情報の出力先を複数選択する。例えば、推奨操作決定部6bは、出力先を2箇所の表示モニターに出力するように選択する、運転者側のスピーカにだけ音声出力するように選択する、などの変更を行う。
推奨操作決定部6bは、例えば、難易度判定部9から入力された難易度が「2」以上の場合、推奨操作情報の出力件数を決定する。例えば、内容の種別を例に説明すると、推奨操作決定部6bは、操作結果を目視で確認する必要がある内容を削除し、操作結果を目視で確認する必要のない内容のみを残した、出力件数を減らした推奨操作情報を作成する、などの変更を行う。
推奨操作決定部6bは、例えば、難易度判定部9から入力された難易度が「2」以上の場合、推奨操作情報の優先順位を変更する。例えば、内容の種別を例に説明すると、推奨操作決定部6bは、操作結果を目視で確認する必要がある内容の優先順位を下げ、操作結果を目視で確認する必要のない内容の優先順位を上げた推奨操作情報を作成する、などの変更を行う。
推奨操作決定部6bは、推奨操作情報の決定について、難易度判定部9が判定した難易度に応じて行ってもよいし、難易度判定部9が難易度の判定処理に用いる各パラメータの有無で設定してもよい。推奨操作決定部6bが行う判定処理に用いる各パラメータの有無での設定とは、高速道路を走行している場合のみ、フォントを大きくする、後方車両が近づいている場合のみ特定箇所に音声で出力する、などである。また、推奨操作決定部6bは、例えば、車両が右折予定の交差点の700m手前を走行中、「次の案内地点を表示する」を推奨する予定だが、二輪車が自車を追い越そうとしているため、二輪車が自車を通り過ぎてから推奨するように、出力地点を右折予定の交差点の600m手前に変更した推奨操作情報に決定する、などである。
図14は、実施の形態3に係る情報提供装置100bの動作を示すフローチャートである。
図14のフローチャートで示す処理は、実施の形態1の図5および実施の形態2の図9のフローチャートのステップST111の処理が行われた後に、実行されるものとする。
難易度判定部9は、現在位置情報取得部1から車両の現在位置情報を取得し、経路情報取得部2から経路情報を取得すると、車両が現在、推奨操作情報の出力地点を含む移動経路を走行しているか判定を行う(ステップST301)。難易度判定部9は、出力地点を含む移動経路を走行していないと判定した場合(ステップST301;NO)、ステップST301の判定処理を継続する。
難易度判定部9は、ステップST303として、例えばゲリラ豪雨に遭遇した場合、難易度を「3」に設定する。また、難易度判定部9は、ステップST304として、難易度「3」が設定値「2」以上であると判定し、ステップST305として難易度「3」を示す情報と共に、推奨操作情報の変更指示を出力する。推奨操作決定部6bは、ステップST306として、推奨操作情報を変更する。
この実施の形態4では、車両が推奨操作情報の出力地点を含む移動経路を走行している際に、当該移動経路の動的な状況を監視した情報に加えて、静的な経路状況を監視した情報を用いて、移動経路の難易度を判定する構成について説明する。
実施の形態4に係る情報提供装置の構成は、上記実施の形態3の図12に示した情報提供装置の構成と図面上は同様であるため、ブロック図の記載を省略する。また、実施の形態3の情報提供装置100bと同一または相当する部分は、同一の符号を付し、説明を省略する。
難易度判定部9は、これらの移動経路の動的な状況および静的な経路状況を監視した情報のパラメータ数および各パラメータのパラメータ値に基づいて、移動経路の走行し易さを示す難易度で表す。難易度判定部9は、各パラメータのパラメータ値が大きいほど、難易度を高く設定する。
難易度判定部9は、例えば、細い路地で通行人と自車の距離が近い状態、交差点付近で自転車が自車に近づいている状態など、特定の地点で人や軽車両が自車に近づいている状況を示すパラメータを有する場合、難易度「1」と設定する。
難易度判定部9は、例えば、高速道路で車両が速度を落として車線変更をしている状態、幹線道路で二輪車が自車を追い抜こうとしている状態など、特定の地点で周辺車両が自車に近づいている状況を示すパラメータを有する場合、難易度「2」と設定する。
難易度判定部9は、例えば、高速道路での豪雨時、山道での凍結時など、特定の地点で片手をハンドルから手放して操作を行うと非常に複雑度が増す状況を示すパラメータを有する場合、難易度「3」と設定する。
難易度判定部9は、ステップST303として、例えば高速道路でゲリラ豪雨に遭遇した場合、難易度を「3」に設定する。難易度判定部9は、ステップST304として、難易度「3」が設定値「2」以上であると判定し、ステップST305として難易度「3」を示す情報と共に、推奨操作情報の変更指示を出力する。推奨操作決定部6bは、ステップST306として、推奨操作情報を変更する。
この実施の形態5では、推奨操作情報として音声出力または表示出力の出力情報を定義する構成を示す。
実施の形態5に係る情報提供装置の構成は、上記実施の形態3の図12に示した情報提供装置100bの構成と図面上は同様であるため、ブロック図の記載を省略する。また、実施の形態3の情報提供装置100bと同一または相当する部分は、同一の符号を付し、説明を省略する。
推奨操作決定部6bは、推奨操作情報の内容を用いて出力方法を特定する場合、例えば、推奨操作情報の内容が「次のサービスエリアの情報を表示する」であると、車両は必ず高速道路上に位置するので、表示出力と共に音声出力を行う等とする。推奨操作決定部6bは、難易度を用いて特定する場合、例えば、難易度「3」の場合は、必ず音声出力のみを行う等とする。
推奨操作決定部6bは、例えば、難易度「3」の場合、音声出力のみを行うとの出力方法を特定した推奨操作情報を作成する。推奨操作決定部6bは、ステップST307として、変更した推奨操作情報の出力を指示する。
この実施の形態6では、上述した実施の形態1で示した構成を備えた情報提供サーバについて説明する。

また、情報提供サーバ200は、車両300に搭載されたナビゲーションシステム等の車載機器301と接続されている。
経路情報受信部12は、車載機器301から設定された経路情報を受信する。経路情報受信部12は、経路情報として、目的地が設定されているか、設定されていないかを示す情報、目的地が設定されている場合に当該目的地までの経路を示す情報、目的地が設定されている場合に車両300の現在位置から当該目的地までの距離を示す情報、目的地の緯度および経度を示す情報等を受信する。また、経路情報受信部12は、車載機器301から車載機器の情報、車載センサの取得情報、地図データ、道路交通情報、VICSの取得情報、DSRCの取得情報等も取得する。経路情報受信部12は、目的地が設定されているか、設定されていないかを示す情報に関して、例えば、目的地の設定がされている場合を「1」、目的地が設定されていない場合を「0」で示した情報を受信する。経路情報受信部12は、車両300の現在位置から当該目的地までの距離を示す情報に関して、例えば、車両300から目的地までの距離を「1200m」等と示した情報を受信する。
推奨操作定義部4は、現在位置情報受信部11が受信した現在位置情報と、経路情報受信部12が受信した経路情報と、第1の経路状況取得部3が取得した移動予定経路の経路状況を予測した情報とに基づいて、推奨操作情報の内容および出力地点を定義する。
送信部13は、出力制御部7の推奨操作情報の表示制御指示に基づいて、推奨操作情報を、接続された車載機器301に出力する。
上述した実施の形態1-5の情報提供装置100,100a,100bは、例えばスピーカおよび操作画面を備えたナビゲーションシステム等に適用することができる。この実施の形態7では、実施の形態1の情報提供装置をナビゲーションシステムに適用した場合について示す。
