Description

ナビゲーション装置Navigation device
　この発明は、充電設備を利用する電気自動車あるいはプラグインハイブリッド車に搭載されたナビゲーション装置に関する。 The present invention relates to a navigation device mounted on an electric vehicle or a plug-in hybrid vehicle using a charging facility.
　従来のナビゲーション装置として、充電設備の施設情報を予め記憶しておき、施設情報を検索することで最寄りの充電設備を判別するものがある。一方、電気自動車又はプラグインハイブリッド車の需要は、今後増加することが予想され、充電設備の拡充が急がれている。このため、充電設備に関する情報を施設情報として記憶しておく場合、新たな充電設備に関する情報を随時追加又は更新していく必要がある。例えば、特許文献１に開示される従来の技術では、充電手段による充電が行われたタイミングで、位置認識手段により検出された位置が充電場所の位置情報として登録される。 As a conventional navigation device, there is a device that stores facility information of a charging facility in advance and determines the nearest charging facility by searching the facility information. On the other hand, demand for electric vehicles or plug-in hybrid vehicles is expected to increase in the future, and the expansion of charging facilities is urgently needed. For this reason, when the information regarding charging equipment is memorize | stored as facility information, it is necessary to add or update the information regarding new charging equipment at any time. For example, in the conventional technique disclosed in Patent Document 1, the position detected by the position recognizing unit is registered as the position information of the charging place at the timing when charging by the charging unit is performed.
特開２００２－６２１５６号公報JP 2002-62156 A
　特許文献１に代表される従来の技術は、充電手段が充電を行ったことのみを契機として充電場所の位置情報を登録しており、充電に使用される電力を供給する充電設備との関係が明確でなかった。このため、充電設備の位置を登録するには、車両の走行中に行われる回生充電と区別する必要があり、充電の前後で位置が変わっていないかを確認しなければならないという課題があった。 The conventional technology represented by Patent Document 1 registers the location information of the charging place only when the charging means performs charging, and has a relationship with a charging facility that supplies power used for charging. It was not clear. For this reason, in order to register the position of the charging facility, it is necessary to distinguish from regenerative charging performed while the vehicle is running, and there is a problem that it is necessary to check whether the position has changed before and after charging. .
　また、特許文献１では、位置情報以外の充電設備に関する情報、例えば充電の状況や課金情報等の利用形態等を登録することができず、さらに充電設備に関する情報の登録要否や、既に登録された充電設備に関する情報を更新すべきか否かを判断できないという課題があった。 Moreover, in patent document 1, the information regarding charging facilities other than position information, for example, the usage status of charging status, billing information, etc., cannot be registered. There was a problem that it was not possible to determine whether or not the information about the charging facility should be updated.
　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、車両の移動中の回生充電を考慮することなく、充電に利用した充電設備の位置情報を自動的に登録することができ、また、位置以外の充電設備に関する情報を登録でき、さらに既に登録した充電設備に関する情報については必要な情報のみを更新する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 to solve the above-described problems, and can automatically register the position information of the charging facility used for charging without considering regenerative charging while the vehicle is moving. It is another object of the present invention to provide a navigation device that can register information related to a charging facility other than the position, and can update only necessary information regarding information related to a charging facility that has already been registered.
　この発明に係るナビゲーション装置は、バッテリを充電する充電器と、充電器と充電設備との電力経路の接続を監視して、当該充電器によるバッテリの充電動作を検出する充電動作検出部を備えた車両において、バッテリの電力で駆動する前記車両に搭載されたナビゲーション装置であって、自車両の位置情報を検出する位置情報検出部と、充電設備の位置情報を記憶する記憶部と、充電動作検出部によって自車両の充電器による充電動作が検出されると、位置情報検出部により検出された自車両の位置情報を、充電設備の位置情報として記憶部に記憶するナビゲーション処理部とを備える。 A navigation device according to the present invention includes a charger for charging a battery, and a charging operation detection unit that monitors connection of a power path between the charger and the charging facility and detects a charging operation of the battery by the charger.

　充電設備１６は、近年の電気自動車及びプラグインハイブリッド車の普及に合わせて、今後益々設置される傾向にある。このため、ナビゲーション装置１が地図情報として持つ充電設備に関する施設情報の内容は、随時更新する必要がある。また、新たな充電設備に関する施設情報についても適切に追加する必要がある。
　そこで、本発明では、充電動作の開始が検出された時点で、位置情報記憶部８に記憶された充電設備情報（充電履歴情報）を自動的に更新する。 The charging facility 16 tends to be installed more and more in the future in accordance with the popularization of electric vehicles and plug-in hybrid vehicles in recent years. For this reason, it is necessary to update the contents of the facility information related to the charging equipment that the navigation device 1 has as map information. Moreover, it is necessary to add appropriately the facility information regarding the new charging equipment.
Therefore, in the present invention, the charging facility information (charging history information) stored in the position information storage unit 8 is automatically updated when the start of the charging operation is detected.
　次に動作について説明する。
　図２は、実施の形態１に係るナビゲーション装置による充電設備の登録処理を示すフローチャートである。この図に沿って充電設備の登録処理の詳細を述べる。
　充電動作検出部１０ａは、充電器９によるバッテリ１１の充電動作を検出する（ステップＳＴ１）。ここで、充電動作検出部１０ａは、充電動作を検出すると直ちにその旨をナビゲーション処理部６へ通知する。なお、充電動作の検出は、例えば下記のように行う。
（Ａ）充電器９の充電コネクタ１５ａが充電設備１６の充電コネクタ１５ｂに接続されたことを電気的もしくは機械的に検出されると、充電動作が開始されたものとみなす。
（Ｂ）充電器９の充電コネクタ１５ａが充電設備１６の充電コネクタ１５ｂに接続されたことを電気的もしくは機械的に検出し、この接続状態が一定時間継続されると、充電動作が開始されたものとみなす。 Next, the operation will be described.
FIG. 2 is a flowchart showing a charging facility registration process by the navigation device according to the first embodiment. Details of the charging facility registration process will be described with reference to this figure.
Charging operation detector 10a detects charging operation of battery 11 by charger 9 (step ST1). Here, the charging operation detection unit 10a immediately notifies the navigation processing unit 6 when detecting the charging operation. For example, the charging operation is detected as follows.
(A) When it is electrically or mechanically detected that the charging connector 15a of the charger 9 is connected to the charging connector 15b of the charging facility 16, it is considered that the charging operation has started.
(B) When the charging connector 15a of the charger 9 is electrically or mechanically detected to be connected to the charging connector 15b of the charging facility 16, and the connection state is continued for a certain time, the charging operation is started. Consider it a thing.
　ナビゲーション処理部６は、充電動作検出部１０ａから充電動作が検出されたことの通知を受けると、位置情報検出部３に対して現在の自車位置を検出するように指示する。位置情報検出部３は、この指示に応答して現在の自車位置を検出してナビゲーション処理部６へ出力する（ステップＳＴ２）。
　この後、ナビゲーション処理部６は、位置情報検出部３によって検出された現在の自車位置に基づいて位置情報記憶部８を検索することで、現在の自車位置情報に対応する充電設備情報が既に登録されているか否かを判定する（ステップＳＴ３）。ここでは、位置情報検出部３による位置検出の誤差を考慮した所定の位置範囲内に存在する充電設備の充電設備情報が既に登録されているか否かが判定される。
　既に登録されていれば（ステップＳＴ３；ＹＥＳ）、現在の自車位置に相当する充電設備の位置を位置情報記憶部８に登録せず、充電設備の登録処理を終了し、図３を用いて後述する処理へ移行する。 When the navigation processing unit 6 receives a notification that the charging operation has been detected from the charging operation detection unit 10a, the navigation processing unit 6 instructs the position information detection unit 3 to detect the current vehicle position. In response to this instruction, the position information detection unit 3 detects the current vehicle position and outputs it to the navigation processing unit 6 (step ST2).
Thereafter, the navigation processing unit 6 searches the position information storage unit 8 based on the current vehicle position detected by the position information detection unit 3, so that the charging facility information corresponding to the current vehicle position information is obtained. It is determined whether it has already been registered (step ST3). Here, it is determined whether or not charging facility information of a charging facility existing within a predetermined position range in consideration of an error in position detection by the position information detection unit 3 has already been registered.
If it has already been registered (step ST3; YES), the charging facility registration process is terminated without registering the position of the charging facility corresponding to the current host vehicle position in the position information storage unit 8, using FIG. The process proceeds to the process described later.
　一方、未だに登録されていなければ（ステップＳＴ３；ＮＯ）、ナビゲーション処理部６は、充電動作検出部１０ａ及び設備情報取得部１０ｂに対してバッテリ１１の充電状況及び充電設備に関する情報を要求する。充電動作検出部１０ａは、ナビゲーション処理部６からの要求に応じて、充電器９からバッテリ１１の充電状況（充電量）を取得してナビゲーション処理部６へ応答する。さらに、設備情報取得部１０ｂは、ナビゲーション処理部６からの要求に応じて、充電設備に関する情報を取得してナビゲーション処理部６へ応答する。例えば、設備情報取得部１０ｂが、充電コネクタ１５ａ，１５ｂを経由した電力線通信（ＰＬＣ；Power Line Communications）により、充電設備１６から充電設備の種別や充電設備の利用形態の情報を取得する。なお、充電設備１６が接続するスマートグリッドシステムを介して、充電設備に関する情報を取得してもよい。 On the other hand, if not registered yet (step ST3; NO), the navigation processing unit 6 requests the charging operation detection unit 10a and the facility information acquisition unit 10b for information regarding the charging status of the battery 11 and the charging facility. In response to a request from the navigation processing unit 6, the charging operation detection unit 10 a acquires the charging status (charge amount) of the battery 11 from the charger 9 and responds to the navigation processing unit 6. Furthermore, the facility information acquisition unit 10 b acquires information on the charging facility in response to a request from the navigation processing unit 6 and responds to the navigation processing unit 6. For example, the facility information acquisition unit 10b acquires information on the type of the charging facility and the usage form of the charging facility from the charging facility 16 through power line communication (PLC) via the charging connectors 15a and 15b. In addition, you may acquire the information regarding a charging equipment via the smart grid system which the charging equipment 16 connects.
　ナビゲーション処理部６は、充電動作検出部１０ａ及び設備情報取得部１０ｂによって取得されたバッテリ１１の充電状況と充電設備に関する情報を、充電設備１６の充電設備情報として位置情報記憶部８に登録する（ステップＳＴ４）。これにより、位置情報記憶部８には、充電設備１６の充電設備情報として、現在の自車位置に相当する充電設備１６の位置、充電量、充電日時、充電設備１６の種別、課金情報、営業（開放）時間、電話番号等が登録される。 The navigation processing unit 6 registers the charging status of the battery 11 and the information related to the charging facility acquired by the charging operation detecting unit 10a and the facility information acquiring unit 10b in the position information storage unit 8 as the charging facility information of the charging facility 16 ( Step ST4). As a result, the position information storage unit 8 stores, as the charging facility information of the charging facility 16, the position of the charging facility 16 corresponding to the current vehicle position, the amount of charge, the date and time of charging, the type of the charging facility 16, the charging information, (Open) Time, phone number, etc. are registered.
　位置情報記憶部８に登録された充電設備情報は、充電設備の施設情報として、ユーザが利用することができる。例えば、ユーザが入力部５を用いて自車位置周辺の充電設備又は走行中の最寄りの充電設備の検索を要求した場合、ナビゲーション処理部６は、位置情報検出部３により検出された自車位置情報に基づいて自車位置から所定の距離範囲内（又は予想到着時間の所定範囲内）に存在する充電設備の充電設備情報を検索する。そして、ナビゲーション処理部６は、検索結果の充電設備情報を出力部７でユーザへ提示する。ユーザへの提示は、表示モニタの画面に表示された地図上に充電設備を示すアイコンを表示したり、音声案内を行ってもよい。 The charging facility information registered in the location information storage unit 8 can be used by the user as the facility information of the charging facility. For example, when the user uses the input unit 5 to request a search for charging facilities around the vehicle position or the nearest charging facility that is running, the navigation processing unit 6 detects the vehicle position detected by the position information detection unit 3. Based on the information, the charging facility information of the charging facility existing within a predetermined distance range (or within a predetermined range of expected arrival time) from the own vehicle position is searched. Then, the navigation processing unit 6 presents charging facility information as a search result to the user through the output unit 7. For presentation to the user, an icon indicating the charging facility may be displayed on the map displayed on the screen of the display monitor, or voice guidance may be provided.
　なお、現在の自車位置情報に対応する充電設備情報が既に登録されている場合、下記の処理が実施される。
　図３は、実施の形態１に係るナビゲーション装置による充電履歴情報の更新処理を示すフローチャートである。
　ナビゲーション処理部６は、現在の自車位置情報に対応する充電設備情報が位置情報記憶部８に既に登録されている場合、現在の自車位置に相当する充電設備１６の位置情報を登録せず、充電動作検出部１０ａ及び設備情報取得部１０ｂに対して充電状況及び充電設備に関する情報を要求する。
　次に、ナビゲーション処理部６は、充電動作検出部１０ａ及び設備情報取得部１０ｂにより取得されたバッテリ１１の充電状況及び充電設備に関する情報を、位置情報記憶部８に既に登録されている充電設備１６の充電設備情報と比較して更新の要否を判定する（ステップＳＴ１ａ）。 In addition, when the charging equipment information corresponding to the current vehicle position information has already been registered, the following processing is performed.
FIG. 3 is a flowchart showing a charging history information update process by the navigation device according to the first embodiment.
When the charging facility information corresponding to the current vehicle position information is already registered in the position information storage unit 8, the navigation processing unit 6 does not register the position information of the charging facility 16 corresponding to the current vehicle position. The charging operation detection unit 10a and the facility information acquisition unit 10b are requested for information regarding the charging status and the charging facility.
Next, the navigation processing unit 6 includes the charging facility 16 that has already been registered in the position information storage unit 8 with respect to the charging status of the battery 11 and the information regarding the charging facility acquired by the charging operation detection unit 10a and the facility information acquisition unit 10b. To determine whether or not updating is necessary (step ST1a).
　充電動作検出部１０ａ及び設備情報取得部１０ｂによって取得された情報と、位置情報記憶部８に記憶された既存の情報とが一致して更新が不要であると判定した場合（ステップＳＴ１ａ；更新不要）、ナビゲーション処理部６は、そのまま処理を終了する。
　一方、充電動作検出部１０ａ及び設備情報取得部１０ｂにより取得された情報と、位置情報記憶部８に記憶された既存の情報とが一致せず、更新が必要であると判定した場合（ステップＳＴ１ａ；更新要）、ナビゲーション処理部６は、充電動作検出部１０ａ及び設備情報取得部１０ｂにより取得された情報のうち、既存の情報から変更された内容が反映されるように、位置情報記憶部８に既存の充電設備１６の充電設備情報を更新する（ステップＳＴ２ａ）。
　例えば、既存の充電設備情報と異なる新たな種別の充電設備が存在する場合には、位置情報記憶部８に登録されている充電設備情報の“充電設備の種別”を、新たな種別に置き換えて更新するか、又は“充電設備の種別”に新たな種別を追加して更新する。
　充電量、課金情報、営業（開放）時間、電話番号等の情報に変更がある場合には、同様にして位置情報記憶部８の充電設備情報を更新する。 When it is determined that the information acquired by the charging operation detection unit 10a and the facility information acquisition unit 10b matches the existing information stored in the position information storage unit 8 and no update is necessary (step ST1a; no update required) ) The navigation processing unit 6 ends the process as it is.
On the other hand, when it is determined that the information acquired by the charging operation detection unit 10a and the facility information acquisition unit 10b does not match the existing information stored in the position information storage unit 8 and needs to be updated (step ST1a Update required), and the navigation processing unit 6 reflects the contents changed from the existing information among the information acquired by the charging operation detection unit 10a and the facility information acquisition unit 10b. The charging facility information of the existing charging facility 16 is updated (step ST2a).
For example, when there is a new type of charging facility different from the existing charging facility information, the “charging facility type” of the charging facility information registered in the position information storage unit 8 is replaced with a new type. Update or add a new type to “Type of charging equipment”.
When there is a change in information such as the amount of charge, billing information, business (open) time, telephone number, etc., the charging facility information in the location information storage unit 8 is updated in the same manner.
　以上のように、この実施の形態１によれば、バッテリ１１を充電する充電器９と、充電器９と充電設備１６との電力経路の接続を監視して、当該充電器９によるバッテリ１１の充電動作を検出する充電動作検出部１０ａを備えた電気自動車２において、バッテリ１１の電力で駆動する電気自動車２に搭載されたナビゲーション装置１が、電気自動車２の位置情報を検出する位置情報検出部３と、充電設備１６の位置情報を記憶する位置情報記憶部８と、充電動作検出部１０ａによって電気自動車２の充電器９による充電動作が検出されると、位置情報検出部３により検出された電気自動車の位置情報を充電設備１６の位置情報として位置情報記憶部８に記憶するナビゲーション処理部６とを備える。このように構成することにより、充電器９によるバッテリ１１の回生充電を考慮することなく、充電設備１６の位置情報を自動的に登録できるという効果が得られる。 As described above, according to the first embodiment, the connection of the power path between the charger 9 that charges the battery 11 and the charger 9 and the charging facility 16 is monitored.

　また、この実施の形態１によれば、電気自動車２が、充電器９によるバッテリ１１の充電に使用された充電設備１６に関する情報を取得する設備情報取得部１０ｂを備え、ナビゲーション処理部６が、充電動作検出部１０ａによって電気自動車２の充電器９による充電動作が検出されると、設備情報取得部１０ｂにより取得された充電設備１６に関する情報を、位置情報検出部３により検出された位置情報に対応付けて位置情報記憶部８に記憶する。このようにすることで、充電設備１６の位置情報に加えて、充電設備１６に関する情報を自動的に登録できるという効果が得られる。 Moreover, according to this Embodiment 1, the electric vehicle 2 is provided with the equipment information acquisition part 10b which acquires the information regarding the charging equipment 16 used for charge of the battery 11 by the charger 9, and the navigation processing part 6 is the following. When the charging operation by the charger 9 of the electric vehicle 2 is detected by the charging operation detection unit 10a, the information regarding the charging facility 16 acquired by the facility information acquisition unit 10b is converted into the position information detected by the position information detection unit 3. The position information is stored in the position information storage unit 8 in association with each other. By doing in this way, in addition to the positional information on the charging equipment 16, the effect that the information regarding the charging equipment 16 can be registered automatically is acquired.
　さらに、この実施の形態１によれば、ナビゲーション処理部６が、充電動作検出部１０ａによって電気自動車２の充電器９による充電動作が検出されると、位置情報検出部３により検出された位置情報が既に位置情報記憶部８に記憶されているか否かを判定し、既に記憶されていると判定した位置情報を当該位置情報記憶部８に新たに記憶しないので、位置情報記憶部８に不要な位置情報が登録されることを防止できる。 Further, according to the first embodiment, when the navigation processing unit 6 detects the charging operation by the charger 9 of the electric vehicle 2 by the charging operation detection unit 10a, the position information detected by the position information detection unit 3 is detected.
