＜Ａ．実施の形態１＞
＜Ａ−１．構成、動作＞
図１は、実施の形態１に係る音声伝達装置１０１の構成図である。音声伝達装置１０１は、車両の内外間で音声伝達を行う音声伝達部として、車内スピーカ１ａ、車外スピーカ１ｂ、車内マイクロホン２ａ、車外マイクロホン２ｂを備えている。車内マイクロホン２ａと車外スピーカ１ｂは有線あるいは無線で接続されており、当該接続路は車内から車外へ音声信号が伝達される送話パスとなる。また、車外マイクロホン２ｂと車内スピーカ１ａも有線あるいは無線で接続されており、当該接続路は車外から車内へ音声信号が伝達される受話パスとなる。以下の説明では、送話パスと受話パスの両方を併せて通話パスとも呼ぶ。 <A. Embodiment 1>
<A-1. Configuration, operation>
FIG. 1 is a configuration diagram of a sound transmission device 101 according to the first embodiment. The audio transmission device 101 includes an in-vehicle speaker 1a, an out-of-vehicle speaker 1b, an in-vehicle microphone 2a, and an out-of-vehicle microphone 2b as an audio transmission unit that transmits audio between the inside and outside of the vehicle. The in-vehicle microphone 2a and the out-of-vehicle speaker 1b are connected by wire or wirelessly, and the connection path is a transmission path through which an audio signal is transmitted from the inside of the vehicle to the outside of the vehicle. In addition, the outside microphone 2b and the inside speaker 1a are also connected by wire or wirelessly, and the connection path is a receiving path through which an audio signal is transmitted from the outside to the inside of the car. In the following description, both the transmission path and the reception path are collectively referred to as a call path.

さらに、音声伝達装置１０１は、地図情報を保持する地図情報保持部５と、位置情報を検出する位置情報検出部６と、地図情報と位置情報に基づき通話パスのＯＮ／ＯＦＦを制御する通話機能制御部１０を備えている。ここで送話パスをＯＮにするとは、車内の音声が車外スピーカ１ｂから出力される状態にすることをいい、送話パスをＯＦＦにするとは、車内の音声が車外スピーカ１ｂから出力されない状態にすることをいう。また、受話パスをＯＮにするとは、車外の音声が車内スピーカ１ａから出力される状態にすることをいい、受話パスをＯＦＦにするとは、車外の音声が車内スピーカ１ａから出力されない状態にすることをいう。   Further, the voice transmission device 101 includes a map information holding unit 5 that holds map information, a position information detection unit 6 that detects position information, and a call function that controls ON / OFF of a call path based on the map information and the position information. A control unit 10 is provided. When the transmission path is turned on, it means that the in-vehicle sound is output from the outside speaker 1b. When the transmission path is turned off, the in-vehicle sound is not output from the outside speaker 1b. To do. Also, turning on the reception path means that the sound outside the vehicle is output from the in-vehicle speaker 1a, and turning off the reception path means that the sound outside the vehicle is not output from the in-vehicle speaker 1a. Say.

地図情報保持部５では、ＣＤ，ＤＶＤ，ＢＤ，ＨＤＤといった記憶媒体により地図情報が保持されている。また、地図情報を外部のサーバ等から受信した上で当該記憶媒体に保存しても良い。地図情報は、一般的なカーナビゲーションシステムにおける地図表示に用いられる地図情報であり、店舗や図書館といった各施設の位置情報を含んでいる。さらに、花火や祭といった屋外イベントを含む各種イベントについて、開催場所、開催内容、及び開催日時の情報を含んでいても良い。   In the map information holding unit 5, the map information is held by a storage medium such as a CD, a DVD, a BD, or an HDD. Further, the map information may be stored in the storage medium after being received from an external server or the like. The map information is map information used for map display in a general car navigation system, and includes position information of each facility such as a store or a library. Furthermore, it may include information on the location, content, and date and time of various events including outdoor events such as fireworks and festivals.

位置情報検出部６は、例えばＧＰＳ受信器により実現し、緯度と経度で表される車両の現在地の位置情報を検出する。   The position information detection unit 6 is realized by a GPS receiver, for example, and detects position information of the current location of the vehicle represented by latitude and longitude.

通話機能制御部１０は、位置情報検出部６から取得した現在地の位置情報を基に、地図情報を参照して現在地情報を抽出する。現在地情報とは、車両の現在地付近で行われるイベントや現在地付近の施設、道路設備（以下、単に施設という）についての情報である。通話機能制御部１０は、地図情報を参照し、現在地から所定の閾値未満の距離内にあるイベント開催地や施設の情報を現在地情報として抽出する。現在地情報を抽出する当該距離の閾値は、抽出する対象により異なるが、施設の場合は数ｍ程度であり、イベント開催地の場合はより大きい数値となる。なお、イベント開催地の場合は当該イベントの日時情報も参照し、開催日時が現在の時刻に一致するものを抽出する。また、複数の施設の情報が抽出される場合は、例えば最も現在地に近い施設の情報を現在地情報とする。   The call function control unit 10 extracts current location information with reference to map information based on the location information of the current location acquired from the location information detection unit 6. The current location information is information on events, facilities near the current location, and road equipment (hereinafter simply referred to as facilities) that are performed near the current location of the vehicle. The call function control unit 10 refers to the map information and extracts information on event locations and facilities that are within a distance less than a predetermined threshold from the current location as current location information. The distance threshold for extracting the current location information varies depending on the object to be extracted, but is about several meters in the case of a facility, and is a larger numerical value in the case of an event venue. In the case of an event venue, the date and time information of the event is also referred to, and the event whose date matches the current time is extracted. When information on a plurality of facilities is extracted, for example, information on a facility closest to the current location is used as the current location information.

このように抽出した現在地情報に基づき、通話機能制御部１０は通話パスの制御を行う。図２に、現在地情報とそれに基づく通話パスの制御例を示す。現在地情報がドライブスルーの店舗、ガソリンスタンド、ＥＴＣゲートのいずれかを示す場合、搭乗者がこれらの施設を利用するにあたり車外との双方向通話が求められる状況が想定されるので、通話機能制御部１０は送話パスと受話パスを共にＯＮにする制御を行う。また、現在地情報が踏切、ドライブインシアター、花火の開催地のいずれかを示す場合、搭乗者には車外の音声を聞くことが求められる状況が想定されるので、通話機能制御部１０は送話パスをＯＦＦにし、受話パスをＯＮにする制御を行う。例えば、踏切付近では踏切の警告音を聞くためであり、ドライブインシアターでは車外で放送される映画音声を聞くためである。また、花火の開催地では、受話パスをＯＮにすることによって車内に居ながらにして花火の音を聞くことが可能になる。通話機能制御部１０は、地図情報から抽出した現在地情報に基づき通話パスを制御している。言い換えれば、通話機能制御部１０は地図情報に基づき通話パスを制御している。   Based on the current location information extracted in this way, the call function control unit 10 controls the call path. FIG. 2 shows an example of current location information and a call path control based on the current location information. When the current location information indicates a drive-through store, a gas station, or an ETC gate, it is assumed that the passenger is required to make a two-way call with the outside of the vehicle when using these facilities. 10 performs control to turn on both the transmission path and the reception path. In addition, when the current location information indicates any level crossing, drive-in theater, or fireworks venue, it is assumed that the passenger is required to listen to the voice outside the vehicle. Control is performed to turn off the path and turn on the reception path. For example, in order to hear a warning sound of a railroad crossing in the vicinity of a railroad crossing and to listen to a movie sound broadcast outside the vehicle in a drive-in theater. Also, at the fireworks venue, it is possible to listen to the fireworks sound while in the car by turning on the reception path. The call function control unit 10 controls the call path based on the current location information extracted from the map information. In other words, the call function control unit 10 controls the call path based on the map information.

車内マイクロホン２ａ（車外マイクロホン２ｂ）と車外スピーカ１ｂ（車内スピーカ１ａ）がアンプやＤＡＴ等を介して有線で接続されている場合には、当該アンプやＤＡＴ等のハードウェアＩＣの電源のＯＮ／ＯＦＦを制御することによって、通話パスのＯＮ／ＯＦＦの制御が行われる。あるいは、ＭＵＴＥ回路が当該接続路に備えられている場合には、ＭＵＴＥ回路のボリュームを０にすることによって通話パスをＯＦＦにすることが可能である。あるいは、通話パスが無線で構成される場合は、車内マイクロホン２ａ（車外マイクロホン２ｂ）と車外スピーカ１ｂ（車内スピーカ１ａ）の間に設けられるトランスミッタやレシーバの電源のＯＮ／ＯＦＦを制御することによって、通話パスのＯＮ／ＯＦＦの制御が行われる。以上の動作により、音声伝達部の通話機能のＯＮ／ＯＦＦが制御される。   When the in-vehicle microphone 2a (out-vehicle microphone 2b) and the out-of-vehicle speaker 1b (in-vehicle speaker 1a) are connected by wire via an amplifier, DAT, or the like, the power of the hardware IC such as the amplifier or DAT is turned on / off. By controlling this, ON / OFF control of the call path is performed. Alternatively, when the MUTE circuit is provided in the connection path, the call path can be turned off by setting the volume of the MUTE circuit to 0. Alternatively, when the call path is configured wirelessly, by controlling ON / OFF of the power supply of the transmitter and receiver provided between the in-vehicle microphone 2a (out-vehicle microphone 2b) and the out-of-vehicle speaker 1b (in-vehicle speaker 1a), Call path ON / OFF control is performed. With the above operation, ON / OFF of the call function of the voice transmission unit is controlled.

図３は、音声伝達装置１０１における通話機能制御部１０の動作を示すフローチャートである。通話機能制御部１０は、現在地の位置情報を位置情報検出部６から取得する（ステップＳ１）。次に、地図情報保持部５が保持する地図情報を参照し、現在地の位置情報に基づき現在地情報を取得する（ステップＳ２）。次に、ステップＳ２で取得した現在地情報に基づき通話パスの制御を行う（ステップＳ３）。以上の動作は、例えば音声伝達装置１０１の電源がＯＮになったタイミングで開始され、所定の周期で繰り返し行われる。   FIG. 3 is a flowchart showing the operation of the call function control unit 10 in the audio transmission device 101. The call function control unit 10 acquires position information of the current location from the position information detection unit 6 (step S1). Next, the current location information is acquired based on the location information of the current location by referring to the map information held by the map information holding unit 5 (step S2). Next, the call path is controlled based on the current location information acquired in step S2 (step S3). The above operation is started, for example, at the timing when the power of the audio transmission device 101 is turned on, and is repeatedly performed at a predetermined cycle.

音声伝達装置１０１は以上の動作を行うので、搭乗者は通話パスのＯＮ／ＯＦＦを操作する必要がなく、車両の現在地の位置情報に基づき自動的に通話パスのＯＮ／ＯＦＦが行われる。   Since the voice transmission device 101 performs the above operation, the passenger does not need to operate ON / OFF of the call path, and the call path is automatically turned ON / OFF based on the position information of the current location of the vehicle.

＜Ａ−２．変形例＞
なお、以上の説明では、通話パスとして送話パスと受話パスの双方を地図情報に基づき制御することについて説明した。しかし、送話パスと受話パスのいずれか一方のみが音声伝達部により構成され、当該何れか一方のパスのＯＮ／ＯＦＦを制御する構成であっても良い。 <A-2. Modification>
In the above description, the control of both the transmission path and the reception path as the call path based on the map information has been described. However, only one of the transmission path and the reception path may be configured by the voice transmission unit, and ON / OFF of either one of the paths may be controlled.

＜Ａ−３．効果＞
本実施の形態に係る音声伝達装置１０１は、車両の内外間で音声伝達を行う音声伝達部と、車両の現在地の地図情報に基づき、音声伝達部のＯＮ／ＯＦＦを制御する通話機能制御部１０（制御部）とを備える。よって、音声伝達部のＯＮ／ＯＦＦの切り替えが搭乗者の操作によらず、車両の現在地の位置情報に基づき自動的に行われる。 <A-3. Effect>
The voice transmission device 101 according to the present embodiment includes a voice transmission unit that transmits voice between the inside and outside of the vehicle, and a call function control unit 10 that controls ON / OFF of the voice transmission unit based on map information of the current location of the vehicle. (Control part). Therefore, ON / OFF switching of the voice transmission unit is automatically performed based on the position information of the current location of the vehicle, regardless of the passenger's operation.

また、音声伝達部は、車両内に設けられる車内マイクロホン２ａ（第１のマイクロホン）と、車内マイクロホン２ａと接続され車両外に設けられる車外スピーカ１ｂ（第１のスピーカ）とを備える。よって、送話パスのＯＮ／ＯＦＦの切り替えが搭乗者の操作によらず、車両の現在地の位置情報に基づき自動的に行われる。   The sound transmission unit includes an in-vehicle microphone 2a (first microphone) provided in the vehicle and an in-vehicle speaker 1b (first speaker) connected to the in-vehicle microphone 2a and provided outside the vehicle. Therefore, switching of the transmission path ON / OFF is automatically performed based on the position information of the current location of the vehicle, regardless of the passenger's operation.

あるいは、音声伝達部は、車両外に設けられる車外マイクロホン２ｂ（第２のマイクロホン）と車外マイクロホン２ｂと接続され車両内に設けられる車内スピーカ１ａ（第２のスピーカ）とを備える。よって、受話パスのＯＮ／ＯＦＦの切り替えが搭乗者の操作によらず、車両の現在地の位置情報に基づき自動的に行われる。勿論、車外マイクロホン２ｂと車内スピーカ１ａは、車内マイクロホン２ａ及び車外スピーカ１ｂと共に音声伝達部を構成しても良く、その場合には、通話パスのＯＮ／ＯＦＦの切り替えが搭乗者の操作によらず、車両の現在地の位置情報に基づき自動的に行われる。   Alternatively, the sound transmission unit includes an out-of-vehicle microphone 2b (second microphone) provided outside the vehicle and an in-vehicle speaker 1a (second speaker) connected to the out-of-vehicle microphone 2b. Therefore, the ON / OFF switching of the reception path is automatically performed based on the position information of the current location of the vehicle, regardless of the passenger's operation. Of course, the in-vehicle microphone 2b and the in-vehicle speaker 1a may constitute an audio transmission unit together with the in-vehicle microphone 2a and the out-of-vehicle speaker 1b. In this case, switching of the call path ON / OFF is not performed by the passenger's operation. This is automatically performed based on the position information of the current location of the vehicle.

また、地図情報がイベントの開催地、開催内容、及び開催日時の情報を含む場合には、例えば花火などの開催地付近を走行中に、自動的に受話パスをＯＮにして花火の音を車内で聞くという制御が可能になる。また、地図情報が施設や道路設備の情報を含む場合には、例えばドライブスルーの店舗を利用する際に、自動的に送話パスと受話パスの両方をＯＮにして車内外の会話を可能にするという制御が可能になる。また、例えば踏切の近くを走行中には、自動的に受話パスをＯＮにして踏み切りの警告音を車内で聞くという制御が可能になる。   In addition, if the map information includes information about the event location, event details, and date and time, for example, while driving near the event location, such as fireworks, the reception path is automatically turned on and the fireworks sound is heard inside the vehicle. It is possible to control by listening. In addition, when the map information includes information on facilities and road equipment, for example, when using a drive-through store, both the transmission path and the reception path are automatically turned on to enable conversation inside and outside the vehicle. It is possible to control to do. Further, for example, when traveling near a railroad crossing, it is possible to control to automatically turn on the reception path and listen to the warning sound of the railroad crossing in the vehicle.

図４は、実施の形態２に係る音声伝達装置１０２の構成図である。音声伝達装置１０２は、実施の形態１に係る音声伝達装置１０１の構成に加えて、ドア開閉検出部７及び窓開閉検出部８をさらに備えたものである。図４において、音声伝達装置１０１と同一又は対応する構成要素には同一の参照符号を付し、実施の形態１と重複する説明は省略する。 <B. Second Embodiment>
<B-1. Configuration, operation>
FIG. 4 is a configuration diagram of the audio transmission device 102 according to the second embodiment. The audio transmission device 102 further includes a door opening / closing detection unit 7 and a window opening / closing detection unit 8 in addition to the configuration of the audio transmission device 101 according to the first embodiment. In FIG. 4, the same or corresponding components as those of the audio transmission device 101 are denoted by the same reference numerals, and the description overlapping with that in Embodiment 1 is omitted.

ドア開閉検出部７は、車両のドアの開閉状態を検出する。窓開閉検出部８は、車両の窓の開閉状態を検出する。ドアや窓が開いている場合には、送話パスや受話パスをＯＮにしなくても車両内外で音声の伝達が可能であるため、通話機能制御部１０はこれらを共にＯＦＦにする。そして、ドアと窓が共に閉まっている場合にのみ、通話機能制御部１０は実施の形態１で説明した現在地情報に基づく通話パスの制御を行う。   The door open / close detection unit 7 detects the open / closed state of the door of the vehicle. The window opening / closing detection unit 8 detects the opening / closing state of the window of the vehicle. When the door or the window is open, since the voice can be transmitted inside and outside the vehicle without turning on the transmission path and the reception path, the call function control unit 10 turns off both of them. Then, only when both the door and the window are closed, the call function control unit 10 controls the call path based on the current location information described in the first embodiment.

音声伝達装置１０２における通話機能制御部１０の動作のフローチャートを図５に示す。通話機能制御部１０は、ドアの開閉状態をドア開閉検出部７から取得し、窓の開閉状態を窓開閉検出部８から取得する（ステップＳ１１）。次に、通話機能制御部１０はドアと窓の開閉状態を判断する（ステップＳ１２）。ドアと窓のいずれか一方でも開いた状態にあれば（ステップＳ１２でＹｅｓ）、送話パスと受話パスを共にＯＦＦにし（ステップＳ１６）、処理を終了する。一方、ドアと窓が共に閉まっていれば（ステップＳ１２でＮｏ）、ステップＳ１３〜１５で現在地情報に基づく通話パスの制御を行った後、処理を終了する。ステップＳ１３〜Ｓ１５は図３のステップＳ１〜Ｓ３と同様であるので、ここでは説明を省略する。以上の動作は、例えば音声伝達装置１０２の電源がＯＮになったタイミングで開始され、所定の周期で繰り返し行われる。   FIG. 5 shows a flowchart of the operation of the call function control unit 10 in the voice transmission device 102. The call function control unit 10 acquires the open / close state of the door from the door open / close detection unit 7, and acquires the open / close state of the window from the window open / close detection unit 8 (step S11). Next, the call function control unit 10 determines whether the door and window are open or closed (step S12). If either one of the door and the window is open (Yes in step S12), both the transmission path and the reception path are turned off (step S16), and the process is terminated. On the other hand, if both the door and the window are closed (No in step S12), the call path control based on the current location information is performed in steps S13 to S15, and then the process ends. Steps S13 to S15 are the same as steps S1 to S3 in FIG. The above operation is started, for example, at the timing when the power of the audio transmission device 102 is turned on, and is repeatedly performed at a predetermined cycle.

＜Ｂ−２．変形例＞
なお、音声伝達装置１０２はドア開閉検出部７と窓開閉検出部８を備えるものとして説明したが、ドア開閉検出部７と窓開閉検出部８のうち、何れか一方のみを備えていても良い。例えばドア開閉検出部７のみを備える場合には、通話機能制御部１０は、ドアが閉まっているときにのみ現在地情報に基づく通話パスのＯＮ／ＯＦＦ制御を行い、それ以外の場合は送話パスと受話パスを共にＯＦＦにする。 <B-2. Modification>
The audio transmission device 102 has been described as including the door opening / closing detection unit 7 and the window opening / closing detection unit 8, but may include only one of the door opening / closing detection unit 7 and the window opening / closing detection unit 8. . For example, when only the door opening / closing detection unit 7 is provided, the call function control unit 10 performs ON / OFF control of the call path based on the current location information only when the door is closed, and in other cases, the transmission path And turn off both listening paths.

また、音声伝達装置１０２においても、送話パスと受話パスのいずれか一方のみが音声伝達部により構成され、当該何れか一方のパスのＯＮ／ＯＦＦを制御する構成であっても良い。   Also, the voice transmission apparatus 102 may be configured such that only one of the transmission path and the reception path is configured by the voice transmission unit, and ON / OFF of either one of the paths is controlled.

The voice transmission device 102 according to the present embodiment includes a door open / close detection unit 7 that detects the open / closed state of the door, and the call function control unit 10 (control unit) Control ON / OFF of. When the door is open, the voice transmission function based on the current location information is not controlled, so that the control according to the actual usage situation is performed.

本実施の形態の音声伝達装置１０２は、窓の開閉状態を検出する窓開閉検出部８を備え、通話機能制御部１０（制御部）は、窓開閉検出部８の検出結果に基づき音声伝達部のＯＮ／ＯＦＦを制御する。窓が開いている場合は現在地情報に基づく音声伝達機能の制御を行わないので、実際の使用状況に沿った制御が行われる。   The voice transmission device 102 according to the present embodiment includes a window opening / closing detection unit 8 that detects the opening / closing state of the window, and the call function control unit 10 (control unit) Control ON / OFF of.

車両が走行中は車外と通話する必要性に乏しい。そのため、音声伝達装置１０３では、車両が走行中は送話パスと受話パスを共にＯＦＦにし、車両が停止中にのみ現在地情報に基づく通話パスのＯＮ／ＯＦＦ制御を行う。   There is little need to talk outside the vehicle while the vehicle is running. Therefore, the voice transmission device 103 turns off both the transmission path and the reception path while the vehicle is running, and performs ON / OFF control of the call path based on the current location information only when the vehicle is stopped.

音声伝達装置１０３における通話機能制御部１０の動作のフローチャートを図７に示す。通話機能制御部１０は、車両の走行状態を走行状態検出部９から取得する（ステップＳ２１）。次に、通話機能制御部１０は車両が走行中か否かを判断し（ステップＳ２２）、走行中であれば（ステップＳ２２でＹｅｓ）、送話パスと受話パスを共にＯＦＦにし（ステップＳ２６）、処理を終了する。一方、車両が停止中であれば（ステップＳ２２でＮｏ）、ステップＳ２３〜２５で現在地情報に基づく通話パスの制御を行った後、処理を終了する。ステップＳ２３〜Ｓ２５は図３のステップＳ１〜Ｓ３と同様であるので、ここでは説明を省略する。以上の動作は、例えば音声伝達装置１０３の電源がＯＮになったタイミングで開始され、所定の周期で繰り返し行われる。   A flowchart of the operation of the call function control unit 10 in the voice transmission device 103 is shown in FIG. The call function control unit 10 acquires the traveling state of the vehicle from the traveling state detection unit 9 (step S21). Next, the call function control unit 10 determines whether or not the vehicle is traveling (step S22). If the vehicle is traveling (Yes in step S22), both the transmission path and the reception path are turned off (step S26). The process is terminated. On the other hand, if the vehicle is stopped (No in step S22), the call path is controlled based on the current location information in steps S23 to 25, and then the process is terminated. Steps S23 to S25 are the same as steps S1 to S3 in FIG. The above operation is started, for example, at the timing when the power of the audio transmission device 103 is turned on, and is repeatedly performed at a predetermined cycle.
