Description

本発明は、電磁誘導などを用いた無接点充電器、およびそのプログラムに関する。   The present invention relates to a contactless charger using electromagnetic induction or the like, and a program thereof.

近年、携帯電話の高性能化に伴い、その電力消費が大きくなり、車両内においても充電を行えるようにすることが望まれている。また、電磁誘導を用いた無接点充電も実用化が進んでいる。   In recent years, with the improvement in performance of mobile phones, the power consumption thereof has increased, and it is desired that charging can be performed even in a vehicle. In addition, contactless charging using electromagnetic induction has been put into practical use.

この無接点充電器として、携帯通信機器の２次コイルと対向配置して使用する１次コイルと、この１次コイルの通電を制御する充電制御部と、この充電制御部に充電通信部が接続されたものが存在する。また、充電制御部が、周囲の状況により１次コイルの通電を制御するものが知られている（例えば、下記特許文献１参照）。   As this non-contact charger, a primary coil that is used while being opposed to a secondary coil of a mobile communication device, a charging control unit that controls energization of the primary coil, and a charging communication unit connected to the charging control unit There is what was done. In addition, a charging control unit is known that controls energization of a primary coil according to surrounding conditions (for example, see Patent Document 1 below).

特開２００８−２０６２９７号公報JP 2008-206297 A

しかしながら、前記従来例においては、無接点充電器の１次コイルが発する電磁界により、携帯通信機器と基地局との交信の信頼性を著しく低下させてしまうことがあった。   However, in the conventional example, the electromagnetic field generated by the primary coil of the contactless charger may significantly reduce the communication reliability between the mobile communication device and the base station.

すなわち、携帯通信機器として携帯電話が代表的なものであるが、この携帯電話は、通話やデータ交信のため、周辺に存在する複数の基地局から交信状態の良い基地局を選択する。この時、近くに基地局が多く存在する都市部であれば、無接点充電器を自動車に搭載し移動したとしても、接続中の基地局から次の基地局への変更がいずれの基地局からも近い状態を継続することが可能である。   That is, a mobile phone is a typical mobile communication device, but this mobile phone selects a base station in a good communication state from a plurality of base stations existing in the vicinity for a call or data communication. At this time, if it is an urban area where there are many base stations nearby, even if a contactless charger is mounted on a car and moved, any base station can change the connected base station to the next base station. It is possible to continue the close state.

しかし、山間部など基地局と基地局の位置が離れている場所では、携帯通信機器は、基地局のカバーする範囲の境界までその基地局と接続を継続しなければならないことがある。このような時に、無接点充電器の１次コイルが発する電磁界による携帯通信機器と基地局との交信への影響が無視できない状態となり、携帯通信機器と基地局との交信の信頼性を著しく低下させてしまう問題があった。   However, in places where the position of the base station and the base station is remote, such as in a mountainous area, the mobile communication device may have to continue to connect with the base station up to the boundary of the range covered by the base station. In such a case, the influence of the electromagnetic field generated by the primary coil of the contactless charger on the communication between the mobile communication device and the base station cannot be ignored, and the communication reliability between the mobile communication device and the base station is remarkably increased. There was a problem that would decrease.

そこで、本発明は、無接点充電器による充電中における携帯通信機器と基地局との交信の信頼性を向上させることを目的とするものである。   Therefore, an object of the present invention is to improve the reliability of communication between a mobile communication device and a base station during charging by a contactless charger.

そして、この目的を達成するために、本発明に係る無接点充電器は、携帯通信機器の２次コイルと対向配置して使用する１次コイルと、この１次コイルの通電を制御する充電制御部と、この充電制御部に充電通信部が接続された充電器であって、充電通信部は、携帯通信機器が交信する基地局と前記１次コイルとの位置関係を取得するものであり、充電制御部は、前記位置関係により、１次コイルの通電を制御する構成とし、これにより所期の目的を達成するものである。   In order to achieve this object, a contactless charger according to the present invention includes a primary coil that is used so as to face a secondary coil of a portable communication device, and a charge control that controls energization of the primary coil. And a charging communication unit connected to the charging control unit, the charging communication unit acquires a positional relationship between the base station with which the mobile communication device communicates and the primary coil, The charge control unit is configured to control energization of the primary coil based on the positional relationship, thereby achieving an intended purpose.

以上のように本発明は、携帯通信機器の２次コイルと対向配置して使用する１次コイル
と、この１次コイルの通電を制御する充電制御部と、この充電制御部に充電通信部が接続された充電器であって、充電通信部は、携帯通信機器が交信する基地局と前記１次コイルとの位置関係を取得するものであり、充電制御部は、前記位置関係により、１次コイルの通電を制御する構成としたものであるので、所期の目的を達成するものである。 As described above, the present invention includes a primary coil that is used so as to face a secondary coil of a mobile communication device, a charge control unit that controls energization of the primary coil, and a charge communication unit included in the charge control unit. The charging communication unit is a connected charger, and the charging communication unit acquires a positional relationship between the base station with which the mobile communication device communicates and the primary coil, and the charging control unit is configured according to the positional relationship. Since the coil is configured to control energization, the intended purpose is achieved.

すなわち、本発明においては、１次コイルの周辺の基地局の数や、１次コイルと基地局との距離や、基地局間の距離など基地局と１次コイルとの位置関係を取得し、１次コイルの通電を制御するものである。例えば、周辺の基地局の数が多い場合は、携帯通信機器とある基地局との交信品質が悪くなったとしても、代わりとなる基地局と交信することが可能なので、１次コイルの通電を通常状態で継続する。一方、周辺の基地局の数が少なく、基地局と１次コイルとの距離が離れている場合は、携帯通信機器と基地局との交信品質が良くなく、代わりとなる基地局も無いので、１次コイルの通電を抑制、または停止するものである。   That is, in the present invention, the positional relationship between the base station and the primary coil such as the number of base stations around the primary coil, the distance between the primary coil and the base station, and the distance between the base stations is acquired, It controls the energization of the primary coil. For example, if the number of surrounding base stations is large, even if the communication quality between the mobile communication device and a certain base station deteriorates, it is possible to communicate with an alternative base station. Continue in normal state. On the other hand, when the number of surrounding base stations is small and the distance between the base station and the primary coil is long, the communication quality between the mobile communication device and the base station is not good, and there is no alternative base station. It suppresses or stops energization of the primary coil.

これにより、無接点充電器による充電中における携帯通信機器の基地局との交信の信頼性を向上させることができるものである。   Thereby, the reliability of communication with the base station of the portable communication device during charging by the contactless charger can be improved.

In addition, a secondary coil 9 that receives power supplied from the primary coil 8 is mounted inside the mobile communication device 6.

次に、図３を用いて車載用電子機器４、無接点充電器５、および携帯通信機器６の制御ブロックを説明する。   Next, control blocks of the in-vehicle electronic device 4, the contactless charger 5, and the portable communication device 6 will be described with reference to FIG.

まず、車載用電子機器４は、無接点充電器５と交信する電子機器通信部１０と、ＧＰＳ１１（Ｇｌｏｂａｌ Ｐｏｓｉｔｏｎｉｎｇ Ｓｙｓｔｅｍ）と、車載用電子機器４をナビゲーションとして使用する際に必要な地図ＤＢ１２を有する。また、この地図ＤＢ１２には、ナビゲーションに利用する道路情報だけでなく、各種施設情報も保持している。本実施の形態では、地図ＤＢ１２は、携帯通信機器６が交信する基地局の位置情報などを保持している。なお、基地局とは、移動局との交信を行うため陸上に開設する移動しない無線局をいう。   First, the in-vehicle electronic device 4 includes an electronic device communication unit 10 that communicates with the contactless charger 5, a GPS 11 (Global Positioning System), and a map DB 12 that is necessary when using the in-vehicle electronic device 4 as navigation. . The map DB 12 holds not only road information used for navigation but also various facility information. In this Embodiment, map DB12 hold | maintains the positional information etc. of the base station with which the portable communication apparatus 6 communicates. Note that a base station refers to a non-moving radio station that is established on land to communicate with a mobile station.

また、よく知られているように、ＧＰＳ１１および地図ＤＢ１２を使うことにより、自
分が現在、地球上のどこにいるかを緯度経度の情報を使い知ることが可能である。 Further, as is well known, by using the GPS 11 and the map DB 12, it is possible to know where the person is currently on the earth using the latitude and longitude information.

さらに、車載用電子機器４は、経路案内や各種情報をユーザに知らせる表示部１３と、ユーザからの入力を受け付ける入力部１４とを有する。また、近距離通信部１５は、携帯通信機器６からの楽曲データの送受信や、ハンズフリー通話の際に使用するＢｌｕｅｔｏｏｔｈ（登録商標）などの無線交信を行うものである。さらに、車載用電子機器４は、機器全体を制御する電子機器制御部１６を備える。   Furthermore, the vehicle-mounted electronic device 4 includes a display unit 13 that informs the user of route guidance and various information, and an input unit 14 that receives input from the user. The short-range communication unit 15 performs wireless communication such as Bluetooth (registered trademark) used for transmission / reception of music data from the mobile communication device 6 and hands-free calling. Furthermore, the vehicle-mounted electronic device 4 includes an electronic device control unit 16 that controls the entire device.

次に、携帯通信機器６の制御ブロックを説明する。   Next, a control block of the mobile communication device 6 will be described.

無接点充電器５の１次コイル１７（図２の１次コイル８に相当）と対向配置された２次コイル１８（図２の２次コイル９に相当）は、１次コイル１７から電磁誘導を用いた電力を受ける。２次コイル１８で受けた電力は、充電池２１に蓄えられ、携帯通信機器６の電源として機能する。   A secondary coil 18 (corresponding to the secondary coil 9 in FIG. 2) arranged opposite to the primary coil 17 (corresponding to the primary coil 8 in FIG. 2) of the contactless charger 5 is electromagnetically induced from the primary coil 17. Receive power using. The electric power received by the secondary coil 18 is stored in the rechargeable battery 21 and functions as a power source for the mobile communication device 6.

端末制御部２２は、２次コイル１８、充電池２１、およびセルラー通信部２３と接続される。端末制御部２２は、２次コイル１８が受けた電力の充電池２１への充電制御や、セルラー通信部２３の基地局との交信の制御を行う。説明の簡略化のため詳しくは図示していないが、端末制御部２２は、携帯電話としての通話やデータ交信、車載用電子機器４と連携したハンズフリー通話や音楽再生なども実行する。   Terminal control unit 22 is connected to secondary coil 18, rechargeable battery 21, and cellular communication unit 23. The terminal control unit 22 controls charging of the power received by the secondary coil 18 to the rechargeable battery 21 and controls communication of the cellular communication unit 23 with the base station. Although not shown in detail for simplification of explanation, the terminal control unit 22 also executes a call or data communication as a mobile phone, a hands-free call in cooperation with the in-vehicle electronic device 4 or music playback.

次に、無接点充電器５は、携帯通信機器６の２次コイル１８と対向配置して使用する１次コイル１７と、この１次コイル１７を駆動する駆動回路１７ａと、この駆動回路１７ａの通電を制御する充電制御部１９とを備える。この充電制御部１９には、充電通信部２０が接続される。この充電通信部２０は、車載用電子機器４の電子機器通信部１０との交信だけでなく、１次コイル１７と２次コイル１８とを介した電力線通信も行う。なお、車載用電子機器４の近距離通信部１５と無線交信をする構成としてもよい。   Next, the contactless charger 5 includes a primary coil 17 that is used so as to be opposed to the secondary coil 18 of the mobile communication device 6, a drive circuit 17a that drives the primary coil 17, and the drive circuit 17a. And a charge control unit 19 that controls energization. A charging communication unit 20 is connected to the charging control unit 19. The charging communication unit 20 performs not only communication with the electronic device communication unit 10 of the in-vehicle electronic device 4 but also power line communication via the primary coil 17 and the secondary coil 18. The wireless communication with the short-range communication unit 15 of the in-vehicle electronic device 4 may be performed.

さらに、充電通信部２０は、電子機器通信部１０を介して、ＧＰＳ１１と地図ＤＢ１２を使って求めた携帯通信機器６の基地局と１次コイルとの位置関係を取得するものである。なお、携帯通信機器６の基地局と１次コイルとの位置関係は、ＧＰＳ１１と地図ＤＢ１２があれば簡単に求められることは良く知られたことである。したがって、ＧＰＳ１１と地図ＤＢ１２が携帯通信機器６、または無接点充電器５に備えられていれば、携帯通信機器６および無接点充電器５でも携帯通信機器６の基地局と１次コイル１７との位置関係を容易に取得することができる。   Further, the charging communication unit 20 acquires the positional relationship between the base station and the primary coil of the mobile communication device 6 obtained using the GPS 11 and the map DB 12 via the electronic device communication unit 10. It is well known that the positional relationship between the base station of the mobile communication device 6 and the primary coil can be easily obtained with the GPS 11 and the map DB 12. Therefore, if the GPS 11 and the map DB 12 are provided in the mobile communication device 6 or the contactless charger 5, the base station of the mobile communication device 6 and the primary coil 17 are also used in the mobile communication device 6 and the contactless charger 5. The positional relationship can be easily acquired.

充電制御部１９は、前記位置関係を考慮した駆動回路１７ａの通電制御、つまり１次コイル１７の通電制御をすることにより、１次コイル１７が発する電磁界の影響を抑え、携帯通信機器６と基地局との交信の信頼性を向上させることが可能となる。   The charging control unit 19 suppresses the influence of the electromagnetic field generated by the primary coil 17 by performing energization control of the drive circuit 17a in consideration of the positional relationship, that is, energization control of the primary coil 17, and the mobile communication device 6 It becomes possible to improve the reliability of communication with the base station.

以降は、１次コイル１７が発する電磁界が影響を及ぼすとして説明するが、駆動回路１７ａの通電の影響も無視することはできない。   In the following description, it is assumed that the electromagnetic field generated by the primary coil 17 has an influence, but the influence of the energization of the drive circuit 17a cannot be ignored.

図４を用いて、具体的に説明する。   This will be specifically described with reference to FIG.

図４は、車載用電子機器４の表示部１３に自車位置２４と地図を表示させた状態である。また、自車位置２４の近傍に存在する基地局２５、基地局２６、および基地局２７も表示している。なお、それぞれの基地局２５、２６、２７の周りに一点破線で円状の範囲を示している。これは、１次コイル１７が通電状態ではない時に、基地局２５、２６、２７からの電波を携帯通信機器６が受信可能な範囲２８、２９、３０を示している。   FIG. 4 shows a state in which the vehicle position 24 and a map are displayed on the display unit 13 of the in-vehicle electronic device 4. In addition, a base station 25, a base station 26, and a base station 27 existing in the vicinity of the vehicle position 24 are also displayed. A circular area is indicated by a dashed line around each base station 25, 26, 27. This indicates the ranges 28, 29, and 30 in which the mobile communication device 6 can receive radio waves from the base stations 25, 26, and 27 when the primary coil 17 is not energized.

（具体例１）を説明する。   (Specific Example 1) will be described.

充電制御部１９は、前記位置関係が以下の条件１を満たせば、１次コイル１７への通常通電を継続するように１次コイル１７の通電制御をする。なお、通常通電とは、前記位置関係を考慮することなく、満充電になると通電を停止するなど、通常の充電制御をすることである。   The charge control unit 19 controls energization of the primary coil 17 so as to continue normal energization of the primary coil 17 when the positional relationship satisfies the following condition 1. Note that normal energization refers to normal charge control, such as stopping energization when full charge occurs without considering the positional relationship.

条件１：１次コイル１７（自車位置２４）と基地局との距離が予め決められた距離以内である。なお、予め決められた距離とは、１次コイル１７が発する電磁界の影響があったとしても、携帯通信機器６がその距離内にある基地局からの電波が受信可能である範囲を設定する。     Condition 1: The distance between the primary coil 17 (own vehicle position 24) and the base station is within a predetermined distance. The predetermined distance sets a range in which the mobile communication device 6 can receive radio waves from a base station within the distance even if there is an influence of the electromagnetic field generated by the primary coil 17. .

さらに詳しく説明すると、図４では、基地局２６が予め決められた距離内にあり、条件１を満たしているとする。このような場合、仮に基地局２５と携帯通信機器６が交信をしている途中に、充電制御部１９が１次コイル１７に通電を開始したとする。   More specifically, in FIG. 4, it is assumed that the base station 26 is within a predetermined distance and satisfies the condition 1. In such a case, it is assumed that the charging control unit 19 starts energizing the primary coil 17 while the base station 25 and the mobile communication device 6 are communicating.

この時、１次コイル１７が発する電磁界の影響で基地局２５と携帯通信機器６との交信が不可能となっても、携帯通信機器６は、基地局２６と交信が可能であるので、交信が途切れることはない。したがって、充電制御部１９が１次コイル１７への通常通電を継続したとしても携帯通信機器６と基地局との交信の信頼性を維持することができる。   At this time, even if the communication between the base station 25 and the portable communication device 6 becomes impossible due to the influence of the electromagnetic field generated by the primary coil 17, the portable communication device 6 can communicate with the base station 26. Communication is not interrupted. Therefore, even if the charging controller 19 continues normal energization to the primary coil 17, the reliability of communication between the mobile communication device 6 and the base station can be maintained.

つまり、１次コイル１７（自車位置２４）と最も近い基地局とが予め決められた距離以内であればよく、携帯通信機器６と交信している基地局が予め決められた距離以内に無くてもよい。   That is, the primary coil 17 (own vehicle position 24) and the nearest base station need only be within a predetermined distance, and there are no base stations communicating with the mobile communication device 6 within the predetermined distance. May be.

（具体例２）を説明する。   (Specific Example 2) will be described.

充電制御部１９は、前記位置関係が以下の条件２または条件３を満たせば、１次コイル１７への通電を抑制、または停止状態とする。   If the positional relationship satisfies the following condition 2 or condition 3, the charging control unit 19 suppresses the energization of the primary coil 17 or sets the stopped state.

条件２：１次コイル１７と基地局との距離が予め決められた距離以上である。     Condition 2: The distance between the primary coil 17 and the base station is equal to or greater than a predetermined distance.

条件３：前記１次コイルと最も近い基地局との距離が予め決められた距離以上である。     Condition 3: The distance between the primary coil and the nearest base station is not less than a predetermined distance.

これは、図４で基地局２６が存在しない状態を想定している。この場合、基地局２５と基地局２７は、１次コイル１７が発する電磁界の影響で携帯通信機器６との交信が不可能となってしまうことが考えられる。したがって、充電制御部１９が１次コイル１７への通常通電を抑制、または停止状態としなければ、携帯通信機器６と基地局２５または基地局２７との交信の信頼性を維持することができない。   This assumes a state in which the base station 26 does not exist in FIG. In this case, the base station 25 and the base station 27 may not be able to communicate with the mobile communication device 6 due to the influence of the electromagnetic field generated by the primary coil 17. Therefore, unless the charging control unit 19 suppresses the normal energization of the primary coil 17 or puts it in the stopped state, the reliability of communication between the mobile communication device 6 and the base station 25 or the base station 27 cannot be maintained.

以上具体例１、２で説明したように、本実施の形態の無接点充電器５は、携帯通信機器６の２次コイル１８と対向配置して使用する１次コイル１７と、この１次コイル１７の通電を制御する充電制御部１９と、この充電制御部１９に充電通信部２０が接続された無接点充電器であって、充電通信部２０は、携帯通信機器６が交信する基地局と前記１次コイル１７との位置関係を取得するものであり、充電制御部１９は、前記位置関係により、１次コイル１７の通電を制御する構成としたものであるので、所期の目的を達成するものである。周辺の基地局の数が多い場合は、携帯通信機器６とある基地局との交信品質が悪くなったとしても、代わりとなる基地局と交信することが可能なので、１次コイル１７の通
電を通常状態で継続する。一方、周辺の基地局の数が少なく、基地局と１次コイル１７との距離が離れている場合は、携帯通信機器６と基地局との交信品質が良くなく、代わりとなる基地局も無いので、１次コイル１７の通電を抑制、または停止するものである。 As described in the first and second specific examples, the contactless charger 5 of the present embodiment includes the primary coil 17 that is used so as to be opposed to the secondary coil 18 of the mobile communication device 6, and the primary coil. 17 is a non-contact charger in which a charging communication unit 20 is connected to the charging control unit 19. The charging communication unit 20 is connected to a base station with which the mobile communication device 6 communicates. The positional relationship with the primary coil 17 is acquired, and the charging control unit 19 is configured to control the energization of the primary coil 17 according to the positional relationship, and thus achieves the intended purpose. To do. When the number of surrounding base stations is large, even if the communication quality between the mobile communication device 6 and a certain base station deteriorates, it is possible to communicate with an alternative base station. Continue in normal state. On the other hand, when the number of surrounding base stations is small and the distance between the base station and the primary coil 17 is long, the communication quality between the mobile communication device 6 and the base station is not good, and there is no alternative base station. Therefore, the energization of the primary coil 17 is suppressed or stopped.

これにより、無接点充電器５による充電中における携帯通信機器６の基地局との交信の信頼性を向上させることができるものである。   Thereby, the reliability of communication with the base station of the portable communication device 6 during charging by the contactless charger 5 can be improved.

なお、本実施の形態では、充電制御部１９が携帯通信機器６が交信する基地局と１次コイル１７との位置関係を考慮し、１次コイル１７の通電を制御する構成として説明した。しかし、前記位置関係を考慮し、１次コイル１７の通電可否を判断するのは、車載用電子機器４、無接点充電器５、および携帯通信機器６のいずれの場合であっても良い。   In the present embodiment, the charging control unit 19 has been described as a configuration that controls the energization of the primary coil 17 in consideration of the positional relationship between the base station with which the mobile communication device 6 communicates and the primary coil 17. However, in consideration of the positional relationship, whether the primary coil 17 can be energized may be determined in any of the in-vehicle electronic device 4, the contactless charger 5, and the mobile communication device 6.

図５の処理フローは、無接点充電器５に搭載されたプログラムとして説明するが、車載用電子機器４、無接点充電器５、および携帯通信機器６のいずれにもこのプログラムを搭載することが可能である。   The processing flow of FIG. 5 will be described as a program installed in the contactless charger 5, but this program may be installed in any of the in-vehicle electronic device 4, the contactless charger 5, and the mobile communication device 6. Is possible.
