As the surrounding information, for example, brightness around the vehicle, road gradient, presence / absence of a preceding vehicle, and the like are used.
　道路情報取得部１１２は、走行中の道路情報を取得する。道路情報は、例えば、車線数、制限速度などを用いる。道路情報は、車両に設定してあるカメラや、ナビゲーションシステムに記憶されている情報から取得する。 The road information acquisition unit 112 acquires road information while traveling. The road information uses, for example, the number of lanes, the speed limit, and the like. The road information is acquired from information stored in the camera set in the vehicle or the navigation system.
　通信部１１３は、インターネット上の各種サーバと通信を行い、ナビゲーションによる誤認識等の蓄積情報を取得する。例えば、運転者が案内経路通りに案内地点を曲がることができず、ルートの再探索を行った回数等を蓄積したものである。 The communication unit 113 communicates with various servers on the Internet, and acquires accumulated information such as misrecognition by navigation. For example, the number of times that the driver cannot turn the guidance point along the guidance route and has re-searched the route is accumulated.
　車両情報取得部１２０は運転車両の状態を示す車両情報を取得する。車両情報とは、例えば、車両速度、操舵角、ヨーレート、アクセル状態、ブレーキ状態、車両の傾きなどである。車両情報は、ＣＡＮ（コントロールエリアネットワーク）や車速パルスから取得する。 Vehicle information acquisition unit 120 acquires vehicle information indicating the state of the driving vehicle. The vehicle information includes, for example, vehicle speed, steering angle, yaw rate, accelerator state, brake state, vehicle inclination, and the like. Vehicle information is acquired from a CAN (control area network) or vehicle speed pulse.
　運転者状態情報取得部１３０は運転者の状態を示す情報を取得する。運転者状態情報取得部１３０は、車両内に設置されたカメラ等により取得する。運転者状態情報としては、例えば、運転者の視点位置を用いる。視点位置は、運転者の頭部位置、姿勢方向などから推定してもよい。 The driver state information acquisition unit 130 acquires information indicating the state of the driver. The driver state information acquisition unit 130 acquires the information using a camera or the like installed in the vehicle. For example, the driver's viewpoint position is used as the driver state information. The viewpoint position may be estimated from the driver's head position, posture direction, and the like.
　案内制御部１４０は、位置情報取得部１４１より現在の走行位置の情報を取得し、運転者が設定した目的地への経路を案内する。案内制御部１４０は、例えば、ナビゲーションシステムである。案内制御部１４０は、地図データベースを備え、案内地点やその周辺の交差点や道路補間点の座標情報を持つ。尚、地図データベースは案内制御部１４０で管理せず、他の構成要素（図示しないものも含む）で管理してもよい。 The guidance control unit 140 acquires information on the current travel position from the position information acquisition unit 141, and guides the route to the destination set by the driver. The guidance control unit 140 is, for example, a navigation system. The guidance control unit 140 includes a map database, and has coordinate information of a guidance point and its surrounding intersections and road interpolation points. The map database may not be managed by the guidance control unit 140 but may be managed by other components (including those not shown).

The display unit 160 may use a display device that uses a mirror or a lens and projects the content displayed on the liquid crystal or projector as a virtual image to the outside of the vehicle. For example, using a head-up display (HUD), the display control unit 150 superimposes a real image in front of the vehicle as a virtual image for guidance display.
　また、表示部１６０として、液晶などの表示デバイスを用いてもよい。この場合、表示制御部１５０は、車両前方を撮影した映像に誘導表示を重畳したものを表示部１６０に表示させる。 Further, a display device such as a liquid crystal may be used as the display unit 160. In this case, the display control unit 150 causes the display unit 160 to display an image obtained by capturing the front of the vehicle with a guidance display superimposed thereon.
　［１－２．詳細構成］
　［１－３－２．表示区間］
　本実施の形態の表示制御部２５０は、誘導地点の手前に紛らわしい他の案内地点が存在している場合に、運転者から見て、他の案内地点より手前側と奥側とで誘導表示の表示方法を変更する。表示制御部２５０は、手前側と奥側の表示区間を、以下に示す条件のうち、少なくとも１つの条件を用いて決定する。 [1-2. Detailed configuration]
[1-3-2. Display section]
The display control unit 250 according to the present embodiment, when there is another misleading guidance point in front of the guidance point, displays guidance display on the near side and the far side from the other guidance point as viewed from the driver. Change the display method. The display control unit 250 determines the near-side and back-side display sections using at least one of the following conditions.
　図４に本開示における表示区間の一例を示す。図４は運転者が見ている風景を示し、交差点Ｃが誘導地点、交差点Ｂが交差点Ｃより前に存在する他の案内地点とする。本実施の形態においては、交差点Ｂから自車側を手前側、交差点Ｂから進行方向側を奥側とする。また、誘導地点Ｃから所定の距離手前の誘導表示を開始する地点を案内開始点Ａとする。また、誘導地点Ｃから他の案内地点Ｂまでの区間を第１の区間４０１、他の案内地点から案内開始点までの区間を第２の区間４０２とする。 FIG. 4 shows an example of the display section in the present disclosure. FIG. 4 shows a landscape viewed by the driver, where intersection C is a guidance point, and intersection B is another guidance point existing before intersection C. FIG. In the present embodiment, the vehicle side from the intersection B is the front side, and the traveling direction side from the intersection B is the back side. A point at which guidance display before a predetermined distance from the guidance point C is started is a guidance start point A. A section from the guidance point C to another guidance point B is a first section 401, and a section from another guidance point to a guidance start point is a second section 402.
　表示制御部２５０は、位置情報取得部１４１より入力される走行位置と、案内制御部１４０から取得する地図データベースを用いて第１の区間４０１の距離と、第２の区間４０２の距離を算出する。また、第１の区間を含む第１の誘導表示と、第２の区間４０２を含む第２の誘導表示の表示方法が異なるように制御する。ここで、第１の区間４０１を含むとは、第１の区間４０１の一部を含んでいればよい。同様に、第２の区間を含むとは、第２の区間を一部含んでいればよい。これは、自車の位置に関する精度や車体の揺れなどによる誤差を考慮することに起因する。 The display control unit 250 calculates the distance of the first section 401 and the distance of the second section 402 using the travel position input from the position information acquisition unit 141 and the map database acquired from the guidance control unit 140. . Further, control is performed so that the display method of the first guidance display including the first section and the second guidance display including the second section 402 are different. Here, including the first section 401 only needs to include a part of the first section 401. Similarly, including the second section only needs to include a part of the second section. This is caused by taking into account errors due to the accuracy of the position of the vehicle and the shaking of the vehicle body.
　なお、表示制御部２５０は、第１の区間、第２の区間の距離の算出に、地図データベースの情報ではなく、周辺情報取得部１１１や道路情報取得部１１２より得られる情報を用いて算出してもよい。例えば、表示制御部２５０は、周辺情報取得部１１１より取得される車の傾きを考慮した上で、推定された見かけ上の交差点の位置関係に関する情報に基づいて算出してもよい。一部地図データベースでは、斜面などを考慮しないため、周辺情報取得部１１１や道路情報取得部１１２より得られる情報を用いることで、算出した距離の精度を出すことが出来る。 The display control unit 250 calculates the distance between the first section and the second section using information obtained from the surrounding information acquisition unit 111 and the road information acquisition unit 112 instead of the information in the map database. May be. For example, the display control unit 250 may calculate based on information on the estimated positional relationship of the intersections in consideration of the inclination of the vehicle acquired from the surrounding information acquisition unit 111. In some map databases, slopes and the like are not taken into account, and thus the accuracy of the calculated distance can be obtained by using information obtained from the peripheral information acquisition unit 111 and the road information acquisition unit 112.
　また、表示制御部２５０は、通信部１１３を介して取得した地図情報を用いて、第１の区間、第２の区間の距離を算出してもよい。 Further, the display control unit 250 may calculate the distance between the first section and the second section using the map information acquired through the communication unit 113.
　［１－４．表示方法１］
　図５Ａ、図５Ｂに従来の誘導表示の一例を示す。 [1-4. Display method 1]
5A and 5B show an example of a conventional guidance display.
　誘導表示は、運転者が余裕をもって案内経路へと進入できるよう、交差点から比較的離れた位置から運転手付近まで伸びるような形で表示される。 The guidance display is displayed in a form extending from a position relatively far from the intersection to the vicinity of the driver so that the driver can enter the guide route with a margin.
　図５Ａは案内開始点Ａから誘導地点Ｃ、誘導地点Ｃで左折する案内経路を誘導表示５０１で表示している場合を示す。この場合、運転者は誘導地点Ｃで左側に進路変更を行うことができる。図５Ｂは、誘導表示５０１が案内経路より少しずれてしまった場合を示す。この場合、運転者は誘導地点Ｃではなく、誘導地点Ｃの手前にある他の案内地点Ｂで左折してしまう恐れが生じる。 FIG. 5A shows a case where the guidance display 501 displays a guidance route from the guidance start point A to the guidance point C and a left turn at the guidance point C. In this case, the driver can change the course to the left at the guidance point C. FIG. 5B shows a case where the guidance display 501 is slightly deviated from the guidance route. In this case, the driver may turn left not at the guidance point C but at another guidance point B in front of the guidance point C.
　そこで、本開示の表示制御部２５０は下記に示す表示方法のうち、少なくとも１つの表示方法を用いて第１の区間上と第２の区間上に表示する誘導表示を異ならせる制御を行う。 Therefore, the display control unit 250 of the present disclosure performs control for differentiating the guidance display displayed on the first section and the second section using at least one of the following display methods.
　図６Ａ～６Ｄに実施の形態１における表示方法１の誘導表示の一例を示す。表示方法１は、第１の誘導表示を第２の誘導表示より強調させる表示を行う表示方法である。 FIGS. 6A to 6D show an example of guidance display of the display method 1 in the first embodiment. The display method 1 is a display method for performing display in which the first guidance display is emphasized over the second guidance display.
　図６Ａ～６Ｄにおいて、交差点Ｃを誘導地点、交差点Ｂを他の案内地点、点Ａは案内開始点とする。また、誘導地点Ｃから交差点Ｂまでを第１の区間、交差点Ｂから案内開始点Ａまでを第２の区間とする。また、第１の区間を含む誘導表示は第１の誘導表示６０１、第２の区間を含む誘導表示は第２の誘導表示６０２を表す。図６Ａ～Ｄにおいて、第２の誘導表示として、矢印を使用する場合を例にとって説明する。 6A to 6D, intersection C is a guidance point, intersection B is another guidance point, and point A is a guidance start point. In addition, a section from the guidance point C to the intersection B is a first section, and a section from the intersection B to the guidance start point A is a second section. Further, the guidance display including the first section represents the first guidance display 601, and the guidance display including the second section represents the second guidance display 602. In FIGS. 6A to 6D, a case where an arrow is used as the second guidance display will be described as an example.
　［１－４－１．透明度］
　表示制御部２５０は、第１の誘導表示６０１と第２の誘導表示６０２の透明度を異ならせる。図６Ａでは、表示制御部２５０は、第１の誘導表示６０１の透明度を第２の誘導表示６０２の透明度より下げる。これにより、第２の誘導表示６０２より第１の誘導表示６０１を強調することができる。 [1-4-1. Transparency]
The display control unit 250 changes the transparency of the first guide display 601 and the second guide display 602. In FIG. 6A, the display control unit 250 lowers the transparency of the first guidance display 601 from the transparency of the second guidance display 602. Thereby, the first guidance display 601 can be emphasized from the second guidance display 602.
　［１－４－２．色］
　表示制御部２５０は、第１の誘導表示６０１と第２の誘導表示６０２の色相を異ならせる。図６Ｂでは、表示制御部２５０は、第１の誘導表示６０１の色相を路面が持つ色相とは別の色相へと近づけ、第２の誘導表示６０２の色相を路面の色相へと近づける。これにより、第２の誘導表示６０２より第１の誘導表示６０１を強調することができる。 [1-4-2. color]
The display control unit 250 changes the hues of the first guidance display 601 and the second guidance display 602. In FIG. 6B, the display control unit 250 brings the hue of the first guidance display 601 closer to a hue different from the hue of the road surface, and brings the hue of the second guidance display 602 closer to the hue of the road surface. Thereby, the first guidance display 601 can be emphasized from the second guidance display 602.
　［１－４－３．形状］
　表示制御部２５０は、第１の誘導表示６０１と第２の誘導表示６０２の形状を異ならせる。図６Ｃでは、表示制御部２５０は、第１の誘導表示６０１を実線、第２の誘導表示６０２を破線で表している。これにより、第２の誘導表示６０２より第１の誘導表示６０１を強調することができる。 [1-4-3. shape]
The display control unit 250 changes the shapes of the first guidance display 601 and the second guidance display 602. In FIG. 6C, the display control unit 250 represents the first guidance display 601 with a solid line and the second guidance display 602 with a broken line. Thereby, the first guidance display 601 can be emphasized from the second guidance display 602.
　［１－４－４．種類］
　表示制御部２５０は、第１の誘導表示６０１と第２の誘導表示６０２の種類を異ならせる。図６Ｄでは、第１の誘導表示６０１を矢印、第２の誘導表示６０２をドットで表している。これにより、第２の誘導表示６０２より第１の誘導表示６０１を強調することができる。 [1-4-4. type]
The display control unit 250 changes the types of the first guidance display 601 and the second guidance display 602. In FIG. 6D, the first guidance display 601 is represented by an arrow, and the second guidance display 602 is represented by a dot. Thereby, the first guidance display 601 can be emphasized from the second guidance display 602.
　以上のように、表示制御部２５０は、第１の誘導表示を第２の誘導表示より強調させる表示を行うことで、誘導地点Ｃを他の案内地点Ｂより強調することができる。これにより、誘導表示がずれているような場合であっても、運転者は誘導地点Ｃを認識することが容易になり、間違って案内地点Ｂで進路変更することを軽減できる。 As described above, the display control unit 250 can emphasize the guidance point C from the other guidance points B by performing display that emphasizes the first guidance display from the second guidance display. Thereby, even if the guidance display is shifted, it becomes easy for the driver to recognize the guidance point C, and it is possible to reduce a mistake in changing the course at the guidance point B.
　［１－５．表示方法２］
　表示方法１のように第１の誘導表示を強調する手法のみではなく、実世界との対応関係を考慮する表示方法も考えられる。このような表示方法は、複数の案内地点を区別させようとする際に、運転者に直感的な理解を助けることを可能とする。例えば、複数の左折案内地点を指し示すＦ字のような形状の誘導表示を用い、各区間の表示を制御する。 [1-5. Display method 2]
In addition to the method of emphasizing the first guidance display as in display method 1, a display method that considers the correspondence with the real world is also conceivable. Such a display method can help the driver to understand intuitively when trying to distinguish a plurality of guide points. For example, the display of each section is controlled by using a guidance display having a shape like an F-shape indicating a plurality of left turn guide points.
　図７Ａ～７Ｈに実施の形態１における表示方法２の誘導表示の一例を示す。 7A to 7H show an example of guidance display of the display method 2 in the first embodiment.
　図７Ａ～７Ｈにおいて、交差点Ｃを誘導地点、交差点Ｂを他の案内地点、点Ａは案内開始点とする。また、誘導地点Ｃから案内地点Ｂまでを第１の区間、他の案内地点Ｂから案内開始点Ａまでを第２の区間を示す。各図において、第１の区間を含む誘導表示は第１の誘導表示７０１、第２の区間を含む誘導表示は第２の誘導表示７０２を表す。また、各図において、第１の誘導表示７０１は第２の区間も含むが、本開示では、第２の区間を含む誘導表示とは、第１の区間を含まない誘導表示として説明する。また、図７Ａ～７Ｈにおいては、第１の誘導表示７０１と第２の誘導表示７０２の色を異ならせているが、これは説明のためであり、同じ色にしてもよい。 7A to 7H, intersection C is a guidance point, intersection B is another guidance point, and point A is a guidance start point. Further, the first section is from the guidance point C to the guidance point B, and the second section is from the other guidance point B to the guidance start point A. In each figure, the guidance display including the first section represents the first guidance display 701, and the guidance display including the second section represents the second guidance display 702. In each figure, although the 1st guidance display 701 also includes the 2nd section, in this indication, the guidance display including the 2nd section is explained as the guidance display which does not contain the 1st section. In FIGS. 7A to 7H, the colors of the first guidance display 701 and the second guidance display 702 are different from each other. However, this is for the purpose of explanation, and the same color may be used.
　図７Ａ～図７Ｈでは、誘導表示７０３、７０４に同じ矢印を用い、各矢印の表示方法を変えることにより、案内地点Ｂが誘導地点ではないという直感的な理解を助けている。 7A to 7H, the same arrow is used for the guidance displays 703 and 704, and the display method of each arrow is changed to help intuitive understanding that the guide point B is not a guidance point.
　[１－５－１．記号等による明示]
　図７Ａに示すように、表示制御部２５０は、第１の誘導表示７０１と第２の誘導表示７０２をＦ字状になるように表示させる。表示制御部２５０は、第２の誘導表示７０２が案内経路ではないことを明示するために、第２の誘導表示７０２にバツ印７０３を重畳させる。なお、図７Ａにおいては、バツ印を用いたが、これに限定するものではなく、案内経路ではないことを明示でき記号であればよい。 [1-5-1. Explicit with symbols etc.]
As shown in FIG. 7A, the display control unit 250 displays the first guidance display 701 and the second guidance display 702 in an F shape. The display control unit 250 superimposes a cross mark 703 on the second guidance display 702 to clearly indicate that the second guidance display 702 is not a guide route. In FIG. 7A, a cross mark is used. However, the cross mark is not limited to this, and any symbol that can clearly indicate that the route is not a guide route may be used.
　[１－５－２．形状による明示]
　図７Ｂに示すように、表示制御部２５０は、第１の誘導表示７０１と第２の誘導表示７０２をＦ字状に表示させる。表示制御部２５０は、第２の誘導表示７０２が案内経路ではないことを明示するために、第２の誘導表示７０２を、通常の矢印とは異なる形状になるよう制御する。図７Ｂにおいては、表示制御部２５０は、第２の誘導表示７０２の矢部分を表示しない制御を行っている。なお、図７Ｂにおいては、矢印の矢の部分を表示しない制御を行ったが、これに限定しない。第２の誘導表示７０２が先端に行くほど、細くなる形状などにしてもよい。 [1-5-2. Explicit by shape]
As illustrated in FIG. 7B, the display control unit 250 displays a first guidance display 701 and a second guidance display 702 in an F shape. The display control unit 250 controls the second guide display 702 to have a shape different from that of a normal arrow in order to clearly indicate that the second guide display 702 is not a guide route. In FIG. 7B, the display control unit 250 performs control not to display the arrow portion of the second guidance display 702. In addition, in FIG. 7B, although control which does not display the arrow part of an arrow was performed, it is not limited to this. The second guide display 702 may have a shape that becomes thinner as it goes to the tip.
　[１－５－３．車線幅と線の太さ]
　図７Ｃに示すように、表示制御部２５０は、第１の誘導表示７０１と第２の誘導表示７０２の矢印の太さを異ならせる。例えば、表示制御部２５０は、矢印の太さを、各区間にて交差する道路の幅あるいは車線本数に比例させて表示する。図７Ｃの場合、案内地点Ｂに交差する道路の方が、誘導地点Ｃに交差する道路よりも幅が広いので、第２の誘導表示７０２の矢印の幅は誘導表示７０３の矢印より太く表示されている。これにより、運転者が、幅が広い道路ではなく、幅が狭い道路で左折する認識を促すことができる。 [1-5-3. Lane width and line thickness]
As illustrated in FIG. 7C, the display control unit 250 changes the thicknesses of the arrows of the first guidance display 701 and the second guidance display 702. For example, the display control unit 250 displays the thickness of the arrow in proportion to the width of the road or the number of lanes intersecting in each section. In the case of FIG. 7C, since the road that intersects the guide point B is wider than the road that intersects the guidance point C, the width of the arrow of the second guidance display 702 is displayed wider than the arrow of the guidance display 703. ing. Accordingly, it is possible to prompt the driver to recognize that he / she makes a left turn not on a wide road but on a narrow road.
　[１－５－４．小さな路地の非表示]
　図７Ｄに示すように、案内地点Ｂと交差する道路は、道路幅が極端に小さい。このような道路は、地図データベースには存在しているものの、運転者から見て殆ど視認されない。このような場合、表示制御部２５０は、誘導地点Ｃの近傍に別の交差点は無いと判断し、第２の誘導表示７０２の表示を行わないように制御する。 [1-5-4. Hide small alleys]
As shown in FIG. 7D, the road intersecting with the guide point B has an extremely small road width. Such roads are present in the map database, but are hardly visible to the driver. In such a case, the display control unit 250 determines that there is no other intersection in the vicinity of the guidance point C, and performs control so that the second guidance display 702 is not displayed.
　[１－５－５．アニメーションを用いた明示]
　表示制御部２５０は、第１の誘導表示７０１を強調する為にアニメーションを利用して表示を行う。例えば、図７Ｅに示すように、表示制御部２５０は、第１の誘導表示７０１を明滅させるよう制御する。また、表示制御部２５０は、図７Ｆに示すように、第１の誘導表示７０１内で手前から奥に向かって輝度の高いパーツ７０３をスライドさせてもよい。図７Ｅ、図７Ｆは一例であり、これ以外のアニメーションを利用してもよい。 [1-5-5. Explicit using animation]
The display control unit 250 performs display using animation in order to emphasize the first guidance display 701. For example, as illustrated in FIG. 7E, the display control unit 250 controls the first guidance display 701 to blink. In addition, as shown in FIG. 7F, the display control unit 250 may slide the part 703 with high brightness from the front toward the back in the first guidance display 701. 7E and 7F are examples, and animations other than this may be used.
　[１－５－６．信号、道路標識を用いた明示]
　図７Ｇに示すように、表示制御部２５０は、第１の誘導表示７０１、第２の誘導表示７０２付近の道路上に存在する道標等特徴を表示させる。道標等特徴とは、例えば、信号機や道路標識、横断歩道等である。図７Ｇでは、誘導地点Ｃ付近に存在する信号機７０４を表示している。 [1-5-6. Clear indication using traffic lights and road signs]
As shown in FIG. 7G, the display control unit 250 displays features such as signposts present on the roads in the vicinity of the first guidance display 701 and the second guidance display 702. Features such as signposts are, for example, traffic lights, road signs, pedestrian crossings, and the like. In FIG. 7G, a traffic light 704 existing near the guidance point C is displayed.
　[１－５－７．ランドマークを用いた明示]
　図７Ｈに示すように、表示制御部２５０は、第１の誘導表示７０１、第２の誘導表示７０２付近に存在するランドマークを表示させる。ランドマークは、例えば、特定の店舗やビルを指す文字あるいはシンボル、交差点の名称等を示す。図７Ｈでは、誘導地点Ｃの交差点名７０５、案内地点Ｂの交差点名７０６を表示している。 [1-5-7. Clarification using landmarks]
As illustrated in FIG. 7H, the display control unit 250 displays landmarks that exist in the vicinity of the first guidance display 701 and the second guidance display 702. The landmark indicates, for example, a character or symbol indicating a specific store or building, an intersection name, or the like. In FIG. 7H, an intersection name 705 of the guidance point C and an intersection name 706 of the guidance point B are displayed.
　［１－５－８．路面形状を用いた表示］
　図８Ａ、図８Ｂに本開示の実施の形態１における路面形状を用いた誘導表示の一例を示す。図８Ａ、図８Ｂにおいて、交差点Ｃを誘導地点、交差点Ｂを他の案内地点、点Ａは案内開始点とする。また、誘導地点Ｃから交差点Ｂまでを第１の区間、交差点Ｂから案内地点Ａまでを第２の区間とする。また、第１の区間を含む誘導表示は第１の誘導表示８０１、第２の区間を含む誘導表示は第２の誘導表示８０２を表す。図８Ａ、図８Ｂにおいては、誘導表示として、矢印を使用する。 [1-5-8. Display using road surface shape]
8A and 8B show an example of guidance display using the road surface shape according to the first embodiment of the present disclosure. 8A and 8B, intersection C is a guidance point, intersection B is another guidance point, and point A is a guidance start point. In addition, a section from the guidance point C to the intersection B is a first section, and a section from the intersection B to the guide point A is a second section. The guidance display including the first section represents the first guidance display 801, and the guidance display including the second section represents the second guidance display 802. 8A and 8B, arrows are used as guidance displays.
　図８Ａに示すように、より詳細な路面形状から選ぶべき経路を明示するような場合にも本開示は、適用される。図８Ａでは、表示制御部２５０は、誘導地点Ｃ、交差点Ｂに交差している全ての道路を表示する。図８Ａにおいて、表示制御部２５０は、第１の誘導表示８０１と複数の第２の誘導表示８０２を表示するよう制御する。図８Ａにおいては、表示制御部２５０は、第１の誘導表示８０１と第２の誘導表示８０２の色を異ならせる。 As shown in FIG. 8A, the present disclosure is also applied to a case where a route to be selected from a more detailed road surface shape is clearly indicated. In FIG. 8A, the display control unit 250 displays all roads that intersect the guidance point C and the intersection B. In FIG. 8A, the display control unit 250 controls to display a first guidance display 801 and a plurality of second guidance displays 802. In FIG. 8A, the display control unit 250 changes the colors of the first guide display 801 and the second guide display 802.
　また、図８Ｂに示すように、同一の交差点から複数の分岐があるような場合にも、本開示の手法が適用される。図８Ｂにおいて、誘導地点Ｃと案内地点Ｂは極めて近接しているとみなせる。この場合、表示制御部２５０は、第１の誘導表示８０１と第２の誘導表示８０２を同図のようにＦ字状になるよう表示し、色を異ならせる。 In addition, as shown in FIG. 8B, the method of the present disclosure is also applied when there are a plurality of branches from the same intersection. In FIG. 8B, it can be considered that the guide point C and the guide point B are very close to each other. In this case, the display control unit 250 displays the first guide display 801 and the second guide display 802 in an F shape as shown in FIG.
　なお、表示制御部２５０は、図８Ａ、図８Ｂにおいて、第１の誘導表示と第２の誘導表示を区別するために、色ではなく、透明度などを異ならせてもよい。 It should be noted that the display control unit 250 may change not the color but the transparency in order to distinguish the first guidance display and the second guidance display in FIGS. 8A and 8B.
　［１－６．効果等］
　以上のように、本実施の形態において、車載ナビゲーション装置は、進路変更を行う誘導地点が近づいた時に、誘導地点から所定の距離手前の案内開始点との間に案内地点における進路方向を示す誘導表示を、走行中の道路に重畳するように表示するよう制御する表示制御部を設ける。 [1-6. Effect]
As described above, in the present embodiment, the vehicle-mounted navigation device, when the guidance point where the route is changed, approaches the guidance direction indicating the course direction at the guidance point between the guidance point and the guidance start point before a predetermined distance. A display control unit is provided for controlling the display so that the display is superimposed on the traveling road.
　表示制御部は、誘導地点から案内開始点との間に、他の案内地点が存在する場合、案内地点から他の案内地点までの第１の区間を含む第１の誘導表示と、他の案内地点から案内開始点までの第２の区間の誘導表示を異ならせる。 When there is another guidance point between the guidance point and the guidance start point, the display control unit includes the first guidance display including the first section from the guidance point to the other guidance point, and other guidance points. The guidance display of the second section from the point to the guidance start point is changed.
　これにより、誘導地点の周辺に存在する他の案内地点の位置や、地図データベースや周辺のセンシング結果に応じて、適切な形状にて経路表示を行うので、自車走行位置推定の誤差やガイドの視認性による誘導表示の不明瞭さを軽減する。 As a result, the route is displayed in an appropriate shape according to the position of other guidance points around the guidance point, the map database, and the surrounding sensing results. Reduce the ambiguity of guidance display due to visibility.
　（実施の形態２）
　図９は、本開示の実施の形態２におけるナビゲーション装置３の一構成例を示すブロック図である。図９において、実施の形態１と同じ動作を行う構成要素に対しては、同符号を付与し、説明を省略する。 (Embodiment 2)
FIG. 9 is a block diagram illustrating a configuration example of the navigation device 3 according to the second embodiment of the present disclosure. In FIG. 9, the same reference numerals are given to components that perform the same operations as those in Embodiment 1, and the description thereof is omitted.
　図９に示すように、ナビゲーション装置３は、周辺情報取得部９１１内に撮像部９１４を備える。撮像部９１４は、車両の前方風景を撮像する。また、ナビゲーション装置３は、表示部として液晶ディスプレイ９６０を備える。なお、表示部としては、液晶ディスプレイ以外の表示デバイスを用いても構わない。 As shown in FIG. 9, the navigation device 3 includes an imaging unit 914 in the peripheral information acquisition unit 911. The imaging unit 914 images a front landscape of the vehicle. The navigation device 3 includes a liquid crystal display 960 as a display unit. Note that a display device other than the liquid crystal display may be used as the display unit.
　実施の形態２において、表示制御部９５０は、実施の形態１と同様の動作を行う。ただし、表示制御部９５０は、実施の形態１と異なり、誘導表示を実際の風景に重畳表示させるのではなく、撮像部９１４が撮像した撮像映像に合成させ、合成結果を液晶ディスプレイ９６０に表示させる。 In the second embodiment, the display control unit 950 performs the same operation as in the first embodiment. However, unlike the first embodiment, the display control unit 950 does not superimpose the guidance display on the actual landscape, but synthesizes it with the captured image captured by the imaging unit 914 and displays the combined result on the liquid crystal display 960. .
　（他の実施の形態）
　以上のように、本出願において開示する技術の例示として、実施の形態１～２を説明した。しかしながら、本開示における技術は、これに限定されず、変更、置き換え、付加、省略などを行った実施の形態にも適用できる。また、各記実施の形態で説明した各構成要素を組み合わせて、新たな実施の形態とすることも可能である。 (Other embodiments)
As described above, Embodiments 1 and 2 have been described as examples of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can also be applied to embodiments that have been changed, replaced, added, omitted, and the like. Moreover, it is also possible to combine each component demonstrated by each description embodiment into a new embodiment.
　そこで、以下、他の実施の形態を例示する。 Therefore, other embodiments will be exemplified below.
　本開示では、運転環境取得部は、周辺情報取得部、道路情報取得部、通信部を備えたが、これに限定するものではなく、運転環境を示す情報を取得できるものであればよい。 In the present disclosure, the driving environment acquisition unit includes the peripheral information acquisition unit, the road information acquisition unit, and the communication unit, but is not limited to this, and may be any device that can acquire information indicating the driving environment.
　なお、本開示では、第１の誘導表示と第２の誘導表示で、透明度、色相、形状を異ならせる場合について説明したが、これに限定するものではない。例えば、誘導表示の色、輝度、濃度を変更してもよい。また、第２の誘導表示を図６Ｄに示すドット列に変えて、三角の列や矢印の列を用いてもよい。また、いくつかの表示方法を組み合わせてもよい。 In the present disclosure, the case where the transparency, the hue, and the shape are different between the first guidance display and the second guidance display has been described. However, the present disclosure is not limited to this. For example, the color, brightness, and density of the guidance display may be changed. Further, the second guide display may be changed to the dot row shown in FIG. 6D, and a triangular row or an arrow row may be used. Also, some display methods may be combined.
　また、実施の形態１においては、第１の区間と第２の区間の距離を、案内制御部１４０から取得した地図データベースを用いて算出したが、これに限定されない。遠方と近傍とを分割する地点は、前方センサから車の傾き等を考慮したうえで推定された見かけ上の交差点の位置関係に関する情報に基づいてもよい。実際に誘導するべき交差点が強調されるよう誘導表示の見え方を変更することは、運転者への誘導に効果的である。 In the first embodiment, the distance between the first section and the second section is calculated using the map database acquired from the guidance control unit 140, but the present invention is not limited to this. The point where the distant and the vicinity are divided may be based on information regarding the positional relationship of the apparent intersection estimated from the front sensor in consideration of the inclination of the vehicle. Changing the appearance of the guidance display so that the intersection to be actually guided is emphasized is effective for guidance to the driver.
　また、実施の形態１においては、誘導地点から案内開始点までの間に他の案内地点が１つ存在する場合について説明したが、他の案内地点は複数であっても構わない。この場合、最も誘導地点に近い案内地点から案内開始点までの表示方法を同じにすればよい。 In the first embodiment, the case where there is one other guide point between the guidance point and the guidance start point has been described, but there may be a plurality of other guide points. In this case, the display method from the guidance point closest to the guidance point to the guidance start point may be the same.
　また、実施の形態１においては、誘導表示の表示タイミングについては、特に記載していないが、表示制御部は、車両情報取得部から取得できる運転速度に応じて表示タイミングを制御してもよい。例えば、運転速度が速い場合は、誘導が急になり運転者が焦って急ブレーキをするなど、危険に陥る要因になる。また、運転速度が遅い場合は、誘導指示を行った後、交差点までの距離が長くなり、右左折の準備する指標にならず、運転者には煩わしい誘導となる。運転速度に応じた表示タイミングにすることにより、誘導が遅いことによる急ブレーキや誘導が早すぎることによる運転者の煩わしさを低減することができる。 In the first embodiment, the display timing of the guidance display is not particularly described, but the display control unit may control the display timing according to the driving speed that can be acquired from the vehicle information acquisition unit. For example, when the driving speed is high, the driver becomes impatient and suddenly brakes suddenly, resulting in danger. When the driving speed is slow, the distance to the intersection is increased after the guidance instruction is given, and it is not an index for preparing a right or left turn, which is troublesome for the driver. By setting the display timing according to the driving speed, it is possible to reduce the troublesomeness of the driver due to sudden braking due to slow guidance and too early guidance.
　また、運転者の運転操作を学習する学習部を備えてもよい。これにより、表示制御部は、学習部より出力される情報も考慮して、表示部に表示する情報の表示方法を制御する。そのため、運転者の運転操作の特徴に応じたタイミングで誘導することができる。なお、運転者の運転操作として、通信部から取得する誤認識等の蓄積情報を用いてもよい。 Further, a learning unit that learns the driving operation of the driver may be provided. Thereby, the display control unit controls the display method of the information displayed on the display unit in consideration of the information output from the learning unit. Therefore, it can guide at the timing according to the feature of the driver's driving operation. In addition, you may use accumulation | storage information, such as a misrecognition acquired from a communication part, as a driver | operator's driving operation.
　また、誘導地点手前近傍の案内地点は、交差点に限定されない。案内地点は、駐車場や建屋入口等、歩道が途切れるなどしていて見た目に紛らわしいような地点であっても構わない。 Also, the guidance point near the guidance point is not limited to the intersection. The guide point may be a point such as a parking lot or a building entrance that is confusing to the eye because the sidewalk is interrupted.
　また、誘導地点において交差する道路と、他の案内地点を交差する道路のそれぞれに道路の太さや信号の設置位置について異なる特徴がある場合、それを加味した変形を行って表現してもよい。 In addition, when there are different characteristics regarding the road thickness and the signal installation position on the road intersecting at the guidance point and the road intersecting other guide points, the modification may be performed by taking into account such characteristics.
　また、表示方法２において、第１の誘導表示と第２の誘導表示の表示方法に表示方法１を適用してもよい。 Further, in the display method 2, the display method 1 may be applied to the display methods of the first guidance display and the second guidance display.
　本開示は、運転者に経路表示を行う車両用表示装置に適用可能である。具体的には、ヘッドアップディスプレイを用いたシステム、ナビゲーションシステムなどに、本開示は適用可能である。 The present disclosure is applicable to a vehicle display device that displays a route to a driver. Specifically, the present disclosure can be applied to a system using a head-up display, a navigation system, and the like.
