　本発明に係る通信制御システムの一実施形態を図面に基づいて説明する。 An embodiment of the communication control system according to the present invention will be described with reference to the drawings.
　図１は、本実施形態に係る通信制御システム１の機能構成の一例を示すブロック図である。通信制御システム１は、通信制御装置１０と、車両センサ２０と、車内センサ２１と、地図情報２２と、端末装置３０とを含む。通信制御装置１０は、車両に搭乗している乗員により利用される車両内の装置であって、端末装置３０と通信可能である。端末装置３０は、車両外部の外部ユーザにより利用される装置であって、通信制御装置１０の通信装置１２と通信可能である。外部ユーザは、例えば、乗員の家族や知人、同僚等である。通信制御装置１０と端末装置３０は、電話機能を有し、音声通話を可能とする。本実施形態では、通信制御装置１０は、運転者が意識朦朧等により正常時の運転ができていないときには、その旨及び車両内の通信装置１２に発呼を行うことの提案を含む報知情報を端末装置３０に送信する。また、端末装置３０を介して報知情報を受けた外部ユーザが通信装置１２に電話をかけた場合、運転者が意識朦朧としているときには、応答操作をすることが難しい可能性がある。そこで、通信制御装置１０は、報知情報が送信された端末装置３０から、音声通話情報の通信開始を要求する発呼に関する発呼情報を受信したときには、通信装置１２と、報知情報が送信された端末装置３０との間で電話機能を実行する実行指令が入力されなくても、通信装置１２と、報知情報が送信された端末装置３０との間で電話機能を実行させる。すなわち、通信制御装置１０は、通信装置１２と、報知情報が送信された端末装置３０との間の電話接続処理を自動的に実行させる。これにより、通信装置１２と端末装置３０との間で音声通話情報を相互に送受信できる状態となる。 FIG. 1 is a block diagram showing an example of the functional configuration of the communication control system 1 according to the present embodiment. The communication control system 1 includes a communication control device 10, a vehicle sensor 20, an in-vehicle sensor 21, map information 22, and a terminal device 30. The communication control device 10 is a device in the vehicle used by the occupants on the vehicle and can communicate with the terminal device 30. The terminal device 30 is a device used by an external user outside the vehicle and can communicate with the communication device 12 of the communication control device 10. External users are, for example, the occupant's family, acquaintances, colleagues, and the like. The communication control device 10 and the terminal device 30 have a telephone function and enable voice communication. In the present embodiment, the communication control device 10 provides notification information including a suggestion to that effect and a proposal to make a call to the communication device 12 in the vehicle when the driver is not able to drive normally due to consciousness or the like. It is transmitted to the terminal device 30. Further, when an external user who receives the notification information via the terminal device 30 calls the communication device 12, it may be difficult to perform a response operation when the driver is unconscious. Therefore, when the communication control device 10 receives the call information regarding the call requesting the start of communication of the voice call information from the terminal device 30 to which the broadcast information is transmitted, the communication device 12 and the broadcast information are transmitted. Even if an execution command for executing the telephone function is not input to the terminal device 30, the telephone function is executed between the communication device 12 and the terminal device 30 to which the notification information is transmitted. That is, the communication control device 10 automatically executes the telephone connection process between the communication device 12 and the terminal device 30 to which the broadcast information is transmitted. As a result, voice call information can be mutually transmitted and received between the communication device 12 and the terminal device 30.
　通信制御装置１０は、コントローラ１１と、通信装置１２と、記憶装置１３と、入力装置１４と、出力装置１５とを備える。コントローラ１１は、ハードウェア及びソフトウェアを備えたコンピュータにより構成され、プログラムを格納したＲＯＭ（Ｒｅａｄ Ｏｎｌｙ Ｍｅｍｏｒｙ）と、このＲＯＭに格納されたプログラムを実行するＣＰＵ（Ｃｅｎｔｒａｌ Ｐｒｏｃｅｓｓｉｎｇ Ｕｎｉｔ）と、アクセス可能な記憶装置として機能するＲＡＭ（Ｒａｎｄｏｍ Ａｃｃｅｓｓ Ｍｅｍｏｒｙ）を備えている。なお、動作回路としては、ＣＰＵに代えて又はこれとともに、ＭＰＵ（Ｍｉｃｒｏ Ｐｒｏｃｅｓｓｉｎｇ Ｕｎｉｔ）、ＤＳＰ（Ｄｉｇｉｔａｌ Ｓｉｇｎａｌ Ｐｒｏｃｅｓｓｏｒ）、ＡＳＩＣ（Ａｐｐｌｉｃａｔｉｏｎ Ｓｐｅｃｉｆｉｃ Ｉｎｔｅｇｒａｔｅｄ Ｃｉｒｃｕｉｔ）、ＦＰＧＡ（Ｆｉｅｌｄ Ｐｒｏｇｒａｍｍａｂｌｅ Ｇａｔｅ Ａｒｒａｙ）などを用いることができる。コントローラ１１は、機能ブロックとして、状態判定部１１０と、通信制御部１１１とを備え、各機能を実現する又は各処理を実行するためのソフトウェアと、ハードウェアとの協働により各機能を実行する。コントローラ１１は、通信制御装置１０全体の処理を制御する。具体的には、まず、コントローラ１１は、通信装置１２により取得された車両の状態に関する車両情報に基づいて、車両が所定の特定状態であるか否かを判定する。車両が所定の特定状態であるとは、車両の位置又は車両の走行態様が異常状態だということである。車両の状態を判定するのは、運転者が意識朦朧等している時には、運転者は正常な運転をすることができないため、車両の状態は運転者の状態の影響を受けるからである。次に、コントローラ１１は、車両が所定の特定状態であると判定される場合には、通信装置１２により報知情報を端末装置３０に送信させる。そして、コントローラ１１は、報知情報が送信された後、報知情報が送信された端末装置３０から発呼に関する発呼情報を受信すると、報知情報が送信された端末装置３０との間で電話機能を実行する実行指令が入力されなくても、通信装置１２により、報知情報が送信された端末装置３０との間で電話機能を実行させる。 The communication control device 10 includes a controller 11, a communication device 12, a storage device 13, an input device 14, and an output device 15. The controller 11 is composed of a computer equipped with hardware and software, and has a ROM (Read Only Memory) that stores a program, a CPU (Central Processing Unit) that executes a program stored in the ROM, and an accessible storage. It is equipped with a RAM (Random Access Memory) that functions as a device. As the operating circuit, MPU (Micro Processing Unit), DSP (Digital Signal Processor), ASIC (Application Specific Integrated Circuit), FPGA (Field Array), etc. can be used instead of or in combination with the CPU. .. The controller 11 includes a state determination unit 110 and a communication control unit 111 as functional blocks, and executes each function in cooperation with software and hardware for realizing each function or executing each process. .. The controller 11 controls the processing of the entire communication control device 10. Specifically, first, the controller 11 determines whether or not the vehicle is in a predetermined specific state based on the vehicle information regarding the state of the vehicle acquired by the communication device 12. The vehicle is in a predetermined specific state means that the position of the vehicle or the traveling mode of the vehicle is in an abnormal state. The reason for determining the state of the vehicle is that the state of the vehicle is affected by the state of the driver because the driver cannot drive normally when the driver is unconscious. Next, when it is determined that the vehicle is in a predetermined specific state, the controller 11 causes the communication device 12 to transmit the notification information to the terminal device 30. Then, when the controller 11 receives the call information regarding the call from the terminal device 30 to which the broadcast information is transmitted after the broadcast information is transmitted, the controller 11 performs a telephone function with the terminal device 30 to which the broadcast information is transmitted. Even if the execution command to be executed is not input, the communication device 12 causes the communication device 12 to execute the telephone function with the terminal device 30 to which the notification information is transmitted.
　状態判定部１１０は、通信装置１２により取得された車両情報に基づいて、車両の状態を判定する。具体的には、状態判定部１１０は、車両情報に基づいて、車両が所定の特定状態であるか否か、すなわち、車両の位置又は車両の走行態様が異常状態であるか否かを判定する。異常状態とは、所定の走行経路又は走行範囲から車両の位置が逸脱している状態、車両の安全装置が作動している状態、車両の挙動が不安定である状態及び車両の車速が急速に変動している状態の少なくともいずれかひとつを含む。以下、それぞれの状態の判定について説明する。 The state determination unit 110 determines the state of the vehicle based on the vehicle information acquired by the communication device 12. Specifically, the state determination unit 110 determines whether or not the vehicle is in a predetermined specific state, that is, whether or not the position of the vehicle or the traveling mode of the vehicle is in an abnormal state, based on the vehicle information. .. An abnormal state is a state in which the position of the vehicle deviates from a predetermined driving route or traveling range, a state in which the safety device of the vehicle is operating, a state in which the behavior of the vehicle is unstable, and a state in which the vehicle speed is rapidly increasing. Includes at least one of the fluctuating states. Hereinafter, the determination of each state will be described.
　状態判定部１１０は、走行経路又は走行範囲と、車両の位置とに基づいて、所定の走行経路又は走行範囲から車両の位置が逸脱しているか否かを判定する。所定の走行経路又は走行範囲は、車両が走行する走行経路又は走行エリアとしてあらかじめ設定される経路又は範囲であって、地図情報２２に基づいて設定される。走行経路又は走行範囲の情報は、記憶装置１３に記憶されている。例えば、乗員は、車両の現在地から目的地までの走行経路を所定の走行経路としてあらかじめ設定することとしてもよいし、地図上の一定のエリアを所定の走行範囲として設定することとしてもよい。また、乗員は、時間に応じて走行経路又は走行範囲を設定することとしてもよい。例えば、乗員は、通勤時間帯の走行経路として、車両の現在地から通勤先までの走行経路を設定してもよい。本実施形態では、状態判定部１１０は、車両の位置情報と、走行経路情報又は走行範囲情報とに基づいて、車両の位置が所定の走行経路又は走行範囲外であると特定される場合、車両の位置が所定の走行経路又は走行範囲から逸脱していると判定する。また、状態判定部１１０は、車両の位置が所定の走行経路又は走行範囲内であると特定される場合、車両の位置が所定の走行経路又は走行範囲から逸脱していないと判定する。 The state determination unit 110 determines whether or not the position of the vehicle deviates from the predetermined travel route or travel range based on the travel route or travel range and the position of the vehicle. The predetermined travel route or travel range is a route or range preset as a travel route or travel area in which the vehicle travels, and is set based on the map information 22. Information on the travel route or travel range is stored in the storage device 13. For example, the occupant may preset a travel route from the current location of the vehicle to the destination as a predetermined travel route, or may set a certain area on the map as a predetermined travel range. Further, the occupant may set the traveling route or the traveling range according to the time. For example, the occupant may set a travel route from the current location of the vehicle to the commuting destination as the travel route during the commuting time. In the present embodiment, the state determination unit 110 determines that the position of the vehicle is outside the predetermined travel route or travel range based on the vehicle position information and the travel route information or the travel range information. It is determined that the position of is deviated from the predetermined traveling route or traveling range. Further, when the position of the vehicle is specified to be within the predetermined travel route or travel range, the state determination unit 110 determines that the position of the vehicle does not deviate from the predetermined travel route or travel range.
　状態判定部１１０は、車両の安全装置が作動しているか否かを判定する。車両の安全装置は、例えば、エアバッグである。また、安全装置は、衝突被害軽減ブレーキであってもよい。状態判定部１１０は、状態情報取得部１２０により取得された安全装置の作動情報の入力があった場合には、車両の安全装置が作動していると判定する。 The state determination unit 110 determines whether or not the vehicle safety device is operating. The vehicle safety device is, for example, an airbag. Further, the safety device may be a collision damage mitigation brake. The state determination unit 110 determines that the vehicle safety device is operating when the operation information of the safety device acquired by the state information acquisition unit 120 is input.
　また、状態判定部１１０は、車両の挙動が不安定であるか否かを判定する。車両の挙動が不安定であるとは、車両が左右にふらついている状態である。例えば、状態判定部１１０は、まず、状態情報取得部１２０により取得された操舵角情報に基づいて、所定時間内に、操舵角の変化量が所定の閾値以上となった回数を算出する。そして、状態判定部１１０は、算出された回数が所定回数以上である場合に、車両の挙動が不安定であると判定する。 Further, the state determination unit 110 determines whether or not the behavior of the vehicle is unstable. Unstable behavior of a vehicle means that the vehicle is swaying from side to side. For example, the state determination unit 110 first calculates the number of times the change amount of the steering angle becomes equal to or more than a predetermined threshold value within a predetermined time based on the steering angle information acquired by the state information acquisition unit 120. Then, the state determination unit 110 determines that the behavior of the vehicle is unstable when the calculated number of times is equal to or more than a predetermined number of times.
　また、状態判定部１１０は、車両の車速が急速に変動しているか否かを判定する。車両の車速が急速に変動しているとは、車両が急減速している状態又は急加速している状態である。具体的には、状態判定部１１０は、状態情報取得部１２０により取得された加速度情報により、車両の減速度が所定の閾値以上であるか否かを判定する。そして、状態判定部１１０は、車両の減速度が所定の閾値以上であると判定される場合には、車両の車速が急速に変動していると判定する。また、状態判定部１１０は、加速度センサ２０２により検出された加速度情報により、車両の加速度が所定の閾値以上であるか否かを判定する。そして、状態判定部１１０は、車両の加速度が所定の閾値以上であると判定される場合には、車両の車速が急速に変動していると判定する。 Further, the state determination unit 110 determines whether or not the vehicle speed of the vehicle is rapidly fluctuating. The rapid fluctuation of the vehicle speed means that the vehicle is suddenly decelerating or accelerating. Specifically, the state determination unit 110 determines whether or not the deceleration of the vehicle is equal to or higher than a predetermined threshold value based on the acceleration information acquired by the state information acquisition unit 120. Then, when it is determined that the deceleration of the vehicle is equal to or higher than a predetermined threshold value, the state determination unit 110 determines that the vehicle speed of the vehicle is rapidly changing. Further, the state determination unit 110 determines whether or not the acceleration of the vehicle is equal to or higher than a predetermined threshold value based on the acceleration information detected by the acceleration sensor 202. Then, when it is determined that the acceleration of the vehicle is equal to or higher than a predetermined threshold value, the state determination unit 110 determines that the vehicle speed of the vehicle is rapidly changing.
　また、状態判定部１１０は、車両が長時間停止している状態又は車両が著しく低い車速で走行している状態である場合に、車両が異常状態であると判定することとしてもよい。例えば、状態判定部１１０は、車両の車速情報に基づいて、所定時間の間、車両の車速が０ｋｍ／時である場合には、車両が長時間停止している状態であると判定する。また、状態判定部１１０は、車両の車速情報に基づいて、所定時間の間、車両の車速が所定の車速以下である場合には、車両が著しく低い車速で走行している状態であると判定する。 Further, the state determination unit 110 may determine that the vehicle is in an abnormal state when the vehicle is stopped for a long time or the vehicle is traveling at a remarkably low vehicle speed. For example, the state determination unit 110 determines that the vehicle has been stopped for a long time when the vehicle speed is 0 km / hour for a predetermined time based on the vehicle speed information of the vehicle. Further, the state determination unit 110 determines that the vehicle is traveling at a significantly low vehicle speed when the vehicle speed is equal to or lower than the predetermined vehicle speed for a predetermined time based on the vehicle speed information of the vehicle. do.
　また、本実施形態では、状態判定部１１０は、車両の状態に基づいて判定を行うこととしているが、これに限らず、車両の乗員の状態に基づいて判定を行うこととしてもよい。例えば、車両が自律走行車両である場合、車両の走行状態は正常であっても、乗員の健康状態に異常があるときがあるからである。また、運転者が手動で車両を運転する場合には、運転者の状態に基づいて判定を行うこととしてもよい。状態判定部１１０は、車内センサ２１により取得された、乗員の状態を含む車内情報に基づいて、乗員が所定の特定状態であるか否か、例えば、乗員が異常状態であるか否かを判定する。具体的には、状態判定部１１０は、乗員の姿勢に基づいて、乗員が異常状態であるか否かを判定する。状態判定部１１０は、車内画像から取得される乗員の頭部の三次元位置情報と姿勢角情報に基づいて、乗員の正常姿勢を基準として乗員の頭部がいずれかの方向に所定値以上乖離している状態が一定時間以上継続したと判定される場合には、乗員が異常状態であると判定する。また、状態判定部１１０は、車内画像から取得される乗員の眼が閉じられている閉眼時間に基づいて、乗員が異常状態であるか否かを判定してもよい。また、状態判定部１１０は、車内情報として、乗員の生体信号、例えば、乗員の心拍数や発汗量等に基づいて、乗員が異常状態であるか否かを判定してもよい。なお、状態判定部１１０は、車両情報及び車内情報の両方を取得して、車両の状態及び乗員の状態を判定することとしてもよいし、車両情報及び車内情報のいずれか一方を取得して、車両の状態及び乗員の状態のいずれか一方を判定することとしてもよい。 Further, in the present embodiment, the state determination unit 110 makes a determination based on the state of the vehicle, but the determination is not limited to this, and the determination may be made based on the state of the occupant of the vehicle. For example, when the vehicle is an autonomous traveling vehicle, even if the traveling condition of the vehicle is normal, the health condition of the occupant may be abnormal. Further, when the driver manually drives the vehicle, the determination may be made based on the state of the driver. The state determination unit 110 determines whether or not the occupant is in a predetermined specific state, for example, whether or not the occupant is in an abnormal state, based on the in-vehicle information including the occupant's state acquired by the in-vehicle sensor 21. do. Specifically, the state determination unit 110 determines whether or not the occupant is in an abnormal state based on the posture of the occupant. The state determination unit 110 deviates the occupant's head by a predetermined value or more in either direction based on the occupant's normal posture based on the three-dimensional position information and the posture angle information of the occupant's head acquired from the in-vehicle image. If it is determined that the occupant has continued for a certain period of time or longer, it is determined that the occupant is in an abnormal state. Further, the state determination unit 110 may determine whether or not the occupant is in an abnormal state based on the eye closing time when the occupant's eyes are closed, which is acquired from the in-vehicle image. Further, the state determination unit 110 may determine whether or not the occupant is in an abnormal state based on the occupant's biological signal, for example, the occupant's heart rate, sweating amount, etc., as in-vehicle information. The state determination unit 110 may acquire both the vehicle information and the in-vehicle information to determine the state of the vehicle and the state of the occupants, or may acquire either the vehicle information or the in-vehicle information. Either the state of the vehicle or the state of the occupant may be determined.
　通信制御部１１１は、通信装置１２の処理を制御する。通信制御部１１１は、状態情報取得部１２０により所定の時間間隔で車両センサ２０から車両情報を取得させる。また、通信制御部１１１は、状態判定部１１０により車両が特定状態であると判定された場合には、報知情報送信部１２１により報知情報を端末装置３０に送信させる。報知情報が端末装置３０に送信された後、報知情報が送信された端末装置３０から発呼情報を受信した場合には、通信制御部１１１は、報知情報が送信された端末装置３０との間で電話機能を実行する実行指令が入力されなくても、電話機能部１２２により、報知情報が送信された端末装置３０との間で電話機能を実行させる。また、通信制御部１１１は、報知情報を端末装置３０に送信していない場合に、端末装置３０から発呼情報を受信したときには、乗員による電話機能の実行指令が入力装置１４に入力されたか否かを判定する。そして、通信制御部１１１は、実行指令が入力装置１４に入力されたと判定される場合には電話機能部１２２により端末装置３０との間で電話機能を実行させる。 The communication control unit 111 controls the processing of the communication device 12. The communication control unit 111 causes the state information acquisition unit 120 to acquire vehicle information from the vehicle sensor 20 at predetermined time intervals. Further, when the state determination unit 110 determines that the vehicle is in a specific state, the communication control unit 111 causes the notification information transmission unit 121 to transmit the notification information to the terminal device 30. After the broadcast information is transmitted to the terminal device 30, when the call information is received from the terminal device 30 to which the broadcast information is transmitted, the communication control unit 111 communicates with the terminal device 30 to which the broadcast information is transmitted. Even if the execution command for executing the telephone function is not input, the telephone function unit 122 causes the telephone function unit 122 to execute the telephone function with the terminal device 30 to which the notification information is transmitted. Further, when the communication control unit 111 receives the call information from the terminal device 30 when the notification information is not transmitted to the terminal device 30, whether or not the command for executing the telephone function by the occupant is input to the input device 14.
