　以下に添付図面を参照して、この発明にかかる情報表示装置、情報表示方法、情報表示プログラムおよび記録媒体の好適な実施の形態を詳細に説明する。 Hereinafter, preferred embodiments of an information display device, an information display method, an information display program, and a recording medium according to the present invention will be described in detail with reference to the accompanying drawings.
（実施の形態）
（情報表示装置の機能的構成）
　まず、この発明の実施の形態にかかる情報表示装置１００の機能的構成について説明する。図１は、本実施の形態にかかる情報表示装置の機能的構成を示すブロック図である。 (Embodiment)
(Functional configuration of information display device)
First, the functional configuration of the information display apparatus 100 according to the embodiment of the present invention will be described. FIG. 1 is a block diagram showing a functional configuration of the information display apparatus according to the present embodiment.
　図１において、情報表示装置１００は、表示部１０１と、記憶部１０２と、入力部１０３と、判断部１０４と、選択部１０５と、探索部１０６と、表示制御部１０７と、を備えている。表示部１０１は、地図データを表示する表示画面を備えている。ここで、地図データは、たとえば記憶部１０２に記憶されている。地図データは、ノードおよびリンクからなる道路ネットワークデータと、施設や道路その他地形（山、川、土地）に関するフィーチャを用いて描画される画像データとを含んでいる。地図データは、文字情報、施設の名称や住所などの施設に関する情報、道路や施設の画像などを含んでいてもよい。 In FIG. 1, the information display device 100 includes a display unit 101, a storage unit 102, an input unit 103, a determination unit 104, a selection unit 105, a search unit 106, and a display control unit 107. . The display unit 101 includes a display screen that displays map data. Here, the map data is stored in the storage unit 102, for example. The map data includes road network data composed of nodes and links, and image data drawn using features relating to facilities, roads, and other terrain (mountains, rivers, land). The map data may include text information, information about facilities such as the name and address of the facility, images of roads and facilities, and the like.
　また、施設に関する情報には、各施設の有する利用目的や利用目的別の駐車地点などの情報が含まれていてもよい。具体的には、たとえば、各施設の有する利用目的と、各施設の周辺にある専門駐車場や提携駐車場、人を送り迎えするために駐車することが可能な停車場などの駐車地点と、を関連付けた情報が含まれていてもよい。 Also, the information on the facility may include information such as the purpose of use of each facility and the parking spot for each purpose of use. Specifically, for example, the purpose of use of each facility is associated with parking spots such as specialized parking lots and affiliated parking lots around each facility, and parking lots where people can park to pick up people. Information may also be included.
　入力部１０３は、利用者から目的地点の入力を受け付ける。入力部１０３は、たとえば表示部１０１に表示された複数の目的地点の中から利用者の所望する目的地点の選択を受け付ける。また、入力部１０３は、たとえば所望する目的地点が含まれるジャンルの選択を受け付けて、選択を受け付けたジャンルに含まれる施設の一覧を表示し、この施設の一覧の中から利用者により選択された施設を目的地点として受け付けてもよい。 The input unit 103 receives an input of a destination point from the user. The input unit 103 receives selection of a destination point desired by the user from among a plurality of destination points displayed on the display unit 101, for example. Further, the input unit 103 receives, for example, selection of a genre including a desired destination point, displays a list of facilities included in the selected genre, and is selected by the user from the list of facilities. You may accept a facility as a destination point.
　判断部１０４は、目的地点が利用目的によって駐車地点の異なる目的地点であるか否かを判断する。判断部１０４は、たとえば、目的地点が、車両によって人を送り迎えするために駐車することが可能な駐車地点が周辺にある施設である場合、この目的地点を利用目的によって駐車地点の異なる目的地点であると判断する。ここで、車両によって人を送り迎えするために駐車することが可能な駐車地点が周辺にある施設としては、駅や空港やフェリーターミナルなどが挙げられる。 The determination unit 104 determines whether the destination point is a destination point with a different parking point depending on the purpose of use. For example, when the destination is a facility in the vicinity of a parking spot that can be parked to pick up a person by a vehicle, the determination unit 104 uses the destination as a destination that differs depending on the purpose of use. Judge that there is. Here, as a facility in the vicinity of a parking spot that can be parked for picking up a person by vehicle, there are a station, an airport, a ferry terminal, and the like.
　また、判断部１０４は、目的地点が複数の施設を有する複合施設である場合、この目的地点を利用目的によって駐車地点の異なる目的地点であると判断する。ここで、複合施設とは、たとえば、複数の専門店や飲食店、映画館などの施設を有するショッピングモールなどが挙げられる。また、複合施設としては、住宅と飲食店とを有するマンション、野球場や複合コンベンション施設などの座席や各施設によって駐車地点の異なる施設でもよい。 In addition, when the destination point is a complex facility having a plurality of facilities, the determination unit 104 determines that this destination point is a destination point with a different parking point depending on the purpose of use. Here, the complex facility includes, for example, a shopping mall having a plurality of specialty stores, restaurants, movie theaters, and the like. In addition, the complex facility may be a condominium having a house and a restaurant, a seat such as a baseball field or a complex convention facility, and a facility with different parking spots depending on each facility.
　選択部１０５は、判断部１０４によって目的地点が利用目的によって駐車地点の異なる目的地点であると判断された場合、この目的地点の有する利用目的の中から利用者の所望する利用目的の選択を受け付ける。選択部１０５は、たとえば表示部１０１に表示された利用目的の一覧から、利用者によって選択された利用目的を受け付ける。 When the determination unit 104 determines that the destination point is a destination point with a different parking point depending on the purpose of use, the selection unit 105 accepts a selection of a usage purpose desired by the user from among the usage purposes of the destination point. . The selection unit 105 receives the usage purpose selected by the user from the usage purpose list displayed on the display unit 101, for example.
　探索部１０６は、判断部１０４によって目的地点が利用目的によって駐車地点の異なる目的地点であると判断された場合、かつ選択部１０５によって利用者の所望する利用目的の選択を受け付けた場合、利用者に選択された利用目的に応じた駐車地点までの経路を探索する。また、探索部１０６は、判断部１０４によって目的地点が利用目的によって駐車地点の異なる目的地点でないと判断された場合には、この目的地点までの経路を探索する。すなわち、探索部１０６は、駐車地点に関わらず、目的地点までの経路を探索する。なお、探索部１０６によって探索する経路の出発地点は、現在地点でもよいし、利用者が指定した地点でもよい。 When the determination unit 104 determines that the destination point is a different destination depending on the purpose of use, and when the selection unit 105 receives a selection of the user's desired use purpose, the search unit 106 The route to the parking spot corresponding to the purpose of use selected is searched. In addition, when the determination unit 104 determines that the destination point is not a destination point with a different parking point depending on the purpose of use, the search unit 106 searches for a route to the destination point. That is, the search unit 106 searches for a route to the destination point regardless of the parking spot. The starting point of the route searched by the search unit 106 may be the current point or a point designated by the user.
　表示制御部１０７は、表示部１０１を制御して利用者に選択された利用目的に応じた駐車地点を表示する。また、表示制御部１０７は、表示部１０１を制御して、探索部１０６によって探索された経路を表示してもよい。 The display control unit 107 controls the display unit 101 to display a parking spot according to the purpose of use selected by the user. The display control unit 107 may display the route searched by the search unit 106 by controlling the display unit 101.
（情報表示装置の情報表示処理手順）
　つぎに、情報表示装置１００の情報表示処理手順について説明する。図２は、情報表示装置の情報表示処理手順を示すフローチャートである。図２のフローチャートにおいて、まず、入力部１０３によって利用者からの目的地点の入力を受け付けるまで待機する（ステップＳ２０１：Ｎｏのループ）。そして、ステップＳ２０１において、利用者からの目的地点の入力を受け付けた場合（ステップＳ２０１：Ｙｅｓ）、判断部１０４によって、ステップＳ２０１において入力の受け付けられた目的地点が利用目的によって駐車地点の異なる目的地点か否かを判断する（ステップＳ２０２）。 (Information display processing procedure of information display device)
Next, an information display processing procedure of the information display device 100 will be described. FIG. 2 is a flowchart showing an information display processing procedure of the information display device. In the flowchart of FIG. 2, first, the process waits until an input of a destination point from the user is received by the input unit 103 (step S201: No loop). And in step S201, when the input of the destination point from a user is received (step S201: Yes), the destination point by which the input was received in step S201 by the judgment part 104 differs in the parking point by a usage purpose. Whether or not (step S202).
　ステップＳ２０２においては、たとえば記憶部１０２に記憶された地図情報に基づいて、目的地点が利用目的によって駐車地点の異なる目的地点か否かを判断する。具体的には、ステップＳ２０１において入力の受け付けられた目的地点が、車両によって人を送り迎えするために駐車することが可能な駐車地点が周辺にある施設である場合、この目的地点を利用目的によって駐車地点の異なる目的地点であると判断する。また、ステップＳ２０１において入力の受け付けられた目的地点が、複数の施設を有する複合施設の場合、この目的地点を利用目的によって駐車地点の異なる目的地点であると判断する。 In step S202, for example, based on the map information stored in the storage unit 102, it is determined whether the destination point is a destination point with a different parking spot depending on the purpose of use. Specifically, if the destination point that is accepted in step S201 is a facility in the vicinity of a parking point that can be parked in order to pick up a person by a vehicle, the destination point is parked according to the purpose of use. It is determined that the destination is a different destination. In addition, when the destination point whose input is accepted in step S201 is a complex facility having a plurality of facilities, it is determined that this destination point is a destination point with a different parking spot depending on the purpose of use.
　つぎに、ステップＳ２０２において目的地点が利用目的によって駐車地点の異なる目的地点であると判断された場合（ステップＳ２０２：Ｙｅｓ）、選択部１０５によって目的地点の有する利用目的の中から利用者の所望する利用目的の選択を受け付ける（ステップＳ２０３）。 Next, when it is determined in step S202 that the destination point is a destination point with a different parking spot depending on the purpose of use (step S202: Yes), the selection unit 105 selects the destination point desired by the user. The selection of the purpose of use is accepted (step S203).
　そして、ステップＳ２０３において、表示制御部１０７によって表示部１０１を制御して、利用者に選択された利用目的に応じた駐車地点を表示する（ステップＳ２０４）。さらに、探索部１０６によって、ステップＳ２０３において利用者に選択された利用目的に応じた駐車地点までの経路を探索して（ステップＳ２０５）、一連の処理を終了する。 In step S203, the display control unit 107 controls the display unit 101 to display a parking spot corresponding to the purpose of use selected by the user (step S204). Further, the search unit 106 searches for a route to the parking spot according to the purpose of use selected by the user in step S203 (step S205), and ends the series of processes.
　一方、ステップＳ２０２において目的地点が利用目的によって駐車地点の異なる目的地点ではないと判断された場合（ステップＳ２０２：Ｎｏ）、探索部１０６によって、ステップＳ２０１において入力の受け付けられた目的地点までの経路を探索して（ステップＳ２０６）、一連の処理を終了する。 On the other hand, when it is determined in step S202 that the destination point is not a destination point with a different parking point depending on the purpose of use (step S202: No), the search unit 106 determines a route to the destination point that has been accepted in step S201. A search is performed (step S206), and a series of processing ends.
　なお、図２のフローチャートにおいては、ステップＳ２０５において利用者に選択された利用目的に応じた駐車地点までの経路を探索するとしているが、これに限るものではない。具体的には、たとえば、ステップＳ２０５を省略し、ステップＳ２０４において利用者に選択された利用目的に応じた駐車地点を表示して、一連の処理を終了してもよい。また、たとえばステップＳ２０４において表示された駐車地点が複数ある場合、複数の駐車地点の中から一の駐車地点の選択を利用者から受け付けて、ステップＳ２０５において一の駐車地点までの経路を探索してもよい。さらに、表示制御部１０７によって表示部１０１を制御して、ステップＳ２０５またはステップＳ２０６において探索された経路を表示してもよい。 In the flowchart of FIG. 2, the route to the parking spot corresponding to the purpose of use selected by the user in step S205 is searched, but the present invention is not limited to this. Specifically, for example, step S205 may be omitted, a parking spot corresponding to the purpose of use selected by the user in step S204 may be displayed, and the series of processes may be terminated. For example, when there are a plurality of parking spots displayed in step S204, a selection of one parking spot from the plurality of parking spots is accepted from the user, and a route to the one parking spot is searched in step S205. Also good. Further, the display unit 101 may be controlled by the display control unit 107 to display the route searched in step S205 or step S206.
　上述したように、本実施の形態によれば、入力部１０３によって利用者から入力を受け付けた目的地点が、判断部１０４によって利用目的によって駐車地点の異なる目的地点であると判断された場合、選択部１０５によって目的地点の有する利用目的の中から利用者の所望する利用目的の選択を受け付けることができる。そして、表示制御部１０７によって表示部１０１を制御して利用者に選択された利用目的に応じた駐車地点を表示することができる。したがって、目的地点の周辺に複数の駐車地点がある場合、利用者の所望する利用目的に合致した駐車地点のみを表示することができる。これによって、利用者は、自身が所望する利用目的に合致した駐車地点を簡単に探すことができる。また、利用者は、異なる利用目的に用いる駐車地点に駐車し、車両を降りた後に移動が大変になることを防ぐことができる。 As described above, according to the present embodiment, when the destination point that has received input from the user by the input unit 103 is determined to be a destination point with a different parking spot depending on the purpose of use, the selection is performed. The unit 105 can accept the selection of the purpose of use desired by the user from among the purposes of use possessed by the destination point. The display control unit 107 can control the display unit 101 to display a parking spot corresponding to the purpose of use selected by the user. Therefore, when there are a plurality of parking spots around the destination point, only the parking spot that matches the usage purpose desired by the user can be displayed. As a result, the user can easily find a parking spot that matches the purpose of use desired by the user. Further, the user can park at a parking spot used for a different purpose of use and prevent the movement from becoming difficult after getting off the vehicle.
　また、本実施の形態によれば、判断部１０４によって、目的地点が、車両によって人を送り迎えするために駐車することが可能な駐車地点が周辺にある施設である場合、この目的地点を利用目的によって駐車地点の異なる目的地点であると判断することができる。したがって、目的地点が、たとえば駅、空港、フェリーターミナルのような、車両によって人を送り迎えする可能性のある施設の場合、利用目的に応じた駐車地点を表示することができる。これによって、利用者は、たとえば人を送り迎えするために車両を一時停車したいだけで、駐車する必要がない場合、停車地点を知ることができる。 Also, according to the present embodiment, when the destination is a facility where there is a parking spot that can be parked for picking up a person by a vehicle, the destination 104 uses the destination as a destination. It can be determined that the destination point is a different parking point. Therefore, when the destination point is a facility such as a station, an airport, or a ferry terminal where there is a possibility that people will be picked up by a vehicle, a parking point according to the purpose of use can be displayed. Thus, the user can know the stop point when he / she wants to temporarily stop the vehicle, for example, to pick up a person and does not need to park.
　また、本実施の形態によれば、判断部１０４によって、目的地点が複数の施設を有する複合施設である場合、この目的地点を利用目的によって駐車地点の異なる目的地点であると判断することができる。したがって、目的地点が、たとえば複数の店舗や映画館などを有し、さらに複数の駐車地点を有する施設の場合、利用者が行きたい店舗や観たい映画館に近い駐車地点や提携している駐車地点を表示することができる。これによって、利用者は、たとえば提携外の駐車地点などに駐車して、余計に駐車料金がかかることを防ぐことができる。 Further, according to the present embodiment, when the destination point is a complex facility having a plurality of facilities, the determination unit 104 can determine that this destination point is a different destination point depending on the purpose of use. . Therefore, if the destination has a plurality of stores, movie theaters, etc., and a facility having a plurality of parking spots, the parking spot close to the store that the user wants to visit or the movie theater that the user wants to watch, or parking that is affiliated The point can be displayed. As a result, the user can park, for example, at a parking spot outside the tie-up and prevent an extra parking fee.
　また、本実施の形態によれば、探索部１０６によって利用者に選択された利用目的に応じた駐車地点までの経路を探索することができる。したがって、利用者は、迷うことなく、所望の利用目的に応じた駐車地点に駐車することができる。 Further, according to the present embodiment, it is possible to search for a route to a parking spot according to the purpose of use selected by the user by the search unit 106. Therefore, the user can park at the parking spot according to the desired usage purpose without hesitation.
　また、本実施の形態によれば、判断部１０４によって目的地点が利用目的によって駐車地点の異なる目的地点でないと判断された場合には、探索部１０６によって目的地点までの経路を探索することができる。したがって、目的地点の周辺に駐車地点が複数あっても、目的地点が利用目的によって駐車地点の異なる目的地点でない場合、通常の経路探索をおこない、目的地点までの経路を探索することができる。これによって、利用者は、複数の駐車地点に惑わされず、目的地点まで到着することができる。 Further, according to the present embodiment, when the determination unit 104 determines that the destination point is not a destination point with a different parking point depending on the purpose of use, the search unit 106 can search for a route to the destination point. .

　また、ステップＳ４０３において目的地点が複合施設ではないと判断された場合（ステップＳ４０３：Ｎｏ）、ステップＳ４０６において所定時間が経過した場合（ステップＳ４０６：Ｙｅｓ）、目的地点までの経路を探索する（ステップＳ４１２）。そして、ステップＳ４１１に進み、探索された経路にしたがって目的地点までの誘導を開始して、一連の処理を終了する。 If it is determined in step S403 that the destination point is not a complex facility (step S403: No), if a predetermined time has elapsed in step S406 (step S406: Yes), a route to the destination point is searched (step S406). S412). And it progresses to step S411, the guidance to the destination point is started according to the searched path | route, and a series of processes are complete | finished.
　なお、図４のフローチャートにおいては、ステップＳ４０２において目的地点が車両によって人を送り迎えするために駐車することが可能な駐車地点が周辺にある施設か否かを判断し、ステップＳ４０３において目的地点が複合施設か否かを判断するとしているが、これに限るものではない。具体的には、たとえば目的地点が利用目的によって駐車地点の異なる目的地点であるか否かを判断し、目的地点が利用目的によって駐車地点の異なる目的地点である場合、ステップＳ４０４に進む構成であればよい。 In the flowchart of FIG. 4, it is determined in step S402 whether or not the destination point is a facility in the vicinity where parking is possible in order to pick up people by the vehicle. In step S403, the destination point is combined. Although it is determined whether it is a facility, it is not limited to this. Specifically, for example, it is determined whether or not the destination point is a destination point with a different parking point depending on the purpose of use, and when the destination point is a destination point with a different parking point depending on the purpose of use, the process proceeds to step S404. That's fine.
　また、図４のフローチャートにおいては、ステップＳ４０９：Ｎｏのループにおいて、利用者の所望する駐車地点の選択を受け付けるまで待機するとしているが、これに限るものではない。具体的には、たとえば利用者の所望する駐車地点の選択を受け付けたと判断されない場合、所定時間が経過したか否かを判断して、所定時間が経過した場合、ステップＳ４１２に進み、目的地点までの経路を探索してもよい。また、たとえば利用者の所望する駐車地点の選択を受け付けない場合、ステップＳ４０４に戻り、再度、利用目的の一覧を表示してもよい。 In the flowchart of FIG. 4, in step S409: No, the process waits until the user selects a desired parking spot. However, the present invention is not limited to this. Specifically, for example, when it is not determined that the user has selected a desired parking spot, it is determined whether or not a predetermined time has passed. If the predetermined time has passed, the process proceeds to step S412 to reach the destination point. The route may be searched. For example, when selection of the parking spot which a user desires is not received, it returns to step S404 and you may display the list of utilization purposes again.
　また、図４のフローチャートにおいては、ステップＳ４１２において目的地点までの経路を探索するとしているが、これに限るものではない。具体的には、たとえばステップＳ４０１：Ｙｅｓにおいて目的地点の入力を受け付けた後であれば、いつ目的地点までの経路を探索してもよい。この場合、ステップＳ４１０においては、目的地点までの経路に変更して、利用目的に応じた駐車地点までの経路を再探索すればよい。 In the flowchart of FIG. 4, the route to the destination point is searched in step S412, but the present invention is not limited to this. Specifically, for example, after receiving the input of the destination point in step S401: Yes, the route to the destination point may be searched at any time. In this case, in step S410, the route to the destination point may be changed and the route to the parking point according to the purpose of use may be searched again.
