図１を参照し、実施形態に係る運転支援制御装置１を含む車両システム１００の構成について説明する。車両システム１００は、車両に搭載可能なシステムであり、例えば、運転支援制御装置１、視界改善機能２及び運転支援機能３を含む。 The configuration of the vehicle system 100 including the driving support control device 1 according to the embodiment will be described with reference to FIG. The vehicle system 100 is a system that can be mounted on a vehicle, and includes, for example, a driving support control device 1, a visibility improving function 2, and a driving support function 3.

車両システム１００には、上記の構成以外に、例えば、アクセルセンサ、ブレーキセンサ、ジャイロセンサ、加速度センサ、カメラ、ミリ波レーダ、LiDAR（Light Detection and Ranging）、超音波センサ（ソナー）、外気温センサ等の各種センサ、ドライブレコーダ、ＧＰＳ（Global Positioning System）受信機、カーナビゲーション装置、車載通信機、及び自動運転機能等を含むことができる。 In addition to the above configurations, the vehicle system 100 includes, for example, an accelerator sensor, a brake sensor, a gyro sensor, an acceleration sensor, a camera, a millimeter wave radar, a LiDAR (Light Detection and Ranging), an ultrasonic sensor (sona), and an outside temperature sensor. Various sensors such as, a drive recorder, a GPS (Global Positioning System) receiver, a car navigation device, an in-vehicle communication device, an automatic driving function, and the like can be included.

運転支援制御装置１は、視界改善機能２に対する操作状況に応じて、運転支援機能３の作動状態を制御する。 The driving support control device 1 controls the operating state of the driving support function 3 according to the operation status of the visibility improving function 2.

視界改善機能２は、ウインドウの内側の曇りを取り除く機能であり、例えば、デフロスターやデフォッガーが該当する。デフロスターは、例えばフロントウインドウ及びフロントドアウインドウの内側の曇りを取り除くものであり、デフォッガーは、例えばリアウインドウの内側の曇りを取り除くものである。 The visibility improving function 2 is a function for removing fogging inside the window, and corresponds to, for example, a defroster or a defogger. The defroster removes the fogging inside the front window and the front door window, for example, and the defogger removes the fogging inside the rear window, for example.

運転支援機能３は、車両の安全性を高めるように運転を支援する機能であり、例えば、車線維持支援機能や、車線逸脱抑制機能、車線逸脱警報機能、先行車追従支援機能が該当する。 The driving support function 3 is a function that supports driving so as to enhance the safety of the vehicle, and corresponds to, for example, a lane keeping support function, a lane departure prevention function, a lane departure warning function, and a preceding vehicle tracking support function.

車線維持支援機能は、例えば、車線の中央付近を走行するようにステアリング操作を支援する機能である。 The lane keeping support function is, for example, a function that assists the steering operation so as to travel near the center of the lane.

車線逸脱抑制機能は、例えば、車線を逸脱しそうになるとステアリングやブレーキ等を制御し、走行中の車線を維持するように車両を制御する機能（Lane Departure Prevention System(LDPS)機能）である。 The lane departure prevention function is, for example, a function (Lane Departure Prevention System (LDPS) function) that controls steering, braking, etc. when the vehicle is about to deviate from the lane, and controls the vehicle so as to maintain the lane in which the vehicle is traveling.

車線逸脱警報機能は、例えば、車線を逸脱しそうになると警報音を鳴らしてディスプレイに警告表示する等し、車線を逸脱しないように支援する機能である。 The lane departure warning function is a function that assists the driver not to deviate from the lane by, for example, sounding an alarm sound and displaying a warning on the display when the vehicle is about to deviate from the lane.

先行車追従支援機能は、例えば、先行車両との車間距離を一定（目標車間距離）に保ちながら先行車両に追従して走行することを支援する機能である。 The preceding vehicle tracking support function is, for example, a function that supports traveling following the preceding vehicle while keeping the distance between the vehicle and the preceding vehicle constant (target vehicle distance).

運転支援制御装置１は、機能的な構成として、例えば、制御部１０を有する。なお、運転支援制御装置１の構成要素は、これに限定されることなく、必要に応じて任意の構成要素を適宜追加することができる。 The driving support control device 1 has, for example, a control unit 10 as a functional configuration. The components of the driving support control device 1 are not limited to this, and any component can be added as needed.

制御部１０は、視界改善機能２に対する操作を検知した場合に、運転支援機能３を作動させる、又は運転支援機能３が作動し易くなるように運転支援機能３の作動基準を変更させる。 When the control unit 10 detects an operation on the visibility improving function 2, it activates the driving support function 3 or changes the operating standard of the driving support function 3 so that the driving support function 3 can be easily operated.

上記の視界改善機能２に対する操作としては、例えば、デフロスター又はデフォッガーをオフからオンに切り替える操作、デフロスター又はデフォッガーの強さを弱から強に切り替える操作、デフロスター又はデフォッガーの強さを所定以上の強さに切り替える操作、が該当する。所定以上の強さは、例えば、運転支援が必要になるウインドウの内側の曇り具合の範囲に基づいて、その範囲内にあるときに選択される強さを勘案して適宜設定することができる。 Examples of the operation for the above-mentioned visibility improvement function 2 include an operation of switching the defroster or defogger from off to on, an operation of switching the strength of the defroster or defogger from weak to strong, and an operation of changing the strength of the defroster or defogger to a predetermined strength or higher. The operation to switch to is applicable. The strength above a predetermined level can be appropriately set based on, for example, the range of cloudiness inside the window in which driving assistance is required, taking into consideration the strength selected when the strength is within that range.

上記の運転支援機能３の作動基準を変更させることには、例えば、車線維持支援機能の車線からのオフセット偏差に対する制御量を通常よりも強めること、車線逸脱抑制機能の制御の介入を通常よりも車線の内側で開始させることや制御量を通常よりも強めること、車線逸脱警報機能の警報音及び警告表示を通常よりも車線の内側で作動させること、先行車追従支援機能の目標車間距離を通常よりも広げること等のように、運転支援機能３の安全マージンが通常よりも広がるように目標値を変更することが該当する。 To change the operating standard of the above-mentioned driving support function 3, for example, the control amount for the offset deviation from the lane of the lane keeping support function is strengthened more than usual, and the intervention of the control of the lane departure prevention function is made more than usual. Start inside the lane, increase the control amount more than usual, operate the warning sound and warning display of the lane departure warning function inside the lane than usual, and set the target inter-vehicle distance of the preceding vehicle follow-up support function normally. It corresponds to changing the target value so that the safety margin of the driving support function 3 is wider than usual, such as making it wider than usual.

ここで、制御部１０は、上記の運転支援機能３を作動させることや、運転支援機能３の作動基準を変更させることに限定されず、運転支援機能３を作動するように運転者に提案することや、運転支援機能３の作動基準を変更するように運転者に提案することとしてもよい。 Here, the control unit 10 is not limited to operating the above-mentioned driving support function 3 or changing the operating standard of the driving support function 3, and proposes to the driver to operate the driving support function 3. It may also be suggested to the driver to change the operating standard of the driving support function 3.

また、制御部１０は、上記の視界改善機能に対する操作に加え、外気温センサやその他のセンサによる測定値を用いて、ウインドウの内側の曇り具合等を判定し、運転支援機能３を作動させる、又は運転支援機能３が作動し易くなるように運転支援機能３の作動基準を変更させることとしてもよい。 Further, in addition to the operation for the above-mentioned visibility improvement function, the control unit 10 determines the degree of cloudiness inside the window by using the measured values by the outside air temperature sensor and other sensors, and activates the driving support function 3. Alternatively, the operating standard of the driving support function 3 may be changed so that the driving support function 3 can be easily operated.

次に、図２を参照し、実施形態に係る運転支援制御装置１の動作の一例について説明する。 Next, an example of the operation of the driving support control device 1 according to the embodiment will be described with reference to FIG.

最初に、運転支援制御装置１の制御部１０は、視界改善機能２に対する操作を検知したかどうかを判定する（ステップＳ１０１）。この判定がＮＯである場合（ステップＳ１０１；ＮＯ）には、ＹＥＳになるまでこの判定を繰り返す。 First, the control unit 10 of the driving support control device 1 determines whether or not the operation for the visibility improving function 2 is detected (step S101). If this determination is NO (step S101; NO), this determination is repeated until YES.

上記ステップＳ１０１において視界改善機能２に対する操作を検知したと判定した場合（ステップＳ１０１；ＹＥＳ）に、運転支援制御装置１の制御部１０は、運転支援機能３が作動しているかどうかを判定する（ステップＳ１０２）。この判定がＹＥＳである場合（ステップＳ１０２；ＹＥＳ）には、本動作を終了する。 When it is determined in step S101 that the operation for the visibility improving function 2 is detected (step S101; YES), the control unit 10 of the driving support control device 1 determines whether or not the driving support function 3 is operating (step S101; YES). Step S102). If this determination is YES (step S102; YES), this operation ends.

上記ステップＳ１０２において運転支援機能３が作動していないと判定した場合（ステップＳ１０２；ＮＯ）に、運転支援制御装置１の制御部１０は、運転支援機能３を作動させる（ステップＳ１０３）。そして、本動作を終了する。 When it is determined in step S102 that the driving support function 3 is not operating (step S102; NO), the control unit 10 of the driving support control device 1 operates the driving support function 3 (step S103). Then, this operation is terminated.

前述したように、実施形態における運転支援制御装置１によれば、視界改善機能２に対する操作を検知した場合に、運転支援機能３を作動させるか、運転支援機能３が作動し易くなるように作動基準を変更させることができる。 As described above, according to the driving support control device 1 in the embodiment, when the operation for the visibility improving function 2 is detected, the driving support function 3 is operated or the driving support function 3 is operated so as to be easy to operate. You can change the criteria.

これにより、車両の安全性を高める運転支援機能３を状況に応じて早めに作動させることが可能となる。 As a result, the driving support function 3 that enhances the safety of the vehicle can be operated earlier depending on the situation.

なお、本発明は、前述した実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において、他の様々な形で実施することができる。このため、上記実施形態はあらゆる点で単なる例示にすぎず、限定的に解釈されるものではない。 The present invention is not limited to the above-described embodiment, and can be implemented in various other forms without departing from the gist of the present invention. For this reason, the above embodiments are merely exemplary in all respects and are not to be construed in a limited manner.
