- the control unit 4 analyzes the captured image captured by the camera 6, so that the illumination of the illumination that is lit among the illuminations that are continuously installed in the traveling direction of the vehicle moving in the tunnel is performed. An interval is obtained, and the position just before the tunnel exit is obtained based on the interval (that is, the approach of the tunnel exit is detected). Specifically, the control unit 4 determines that the brightness and color tone of the vehicle has reached the exit of the tunnel where the brightness and color tone should be adjusted when the interval of lighting during lighting becomes a predetermined value or less. Start adjustment.

- the hatched illumination indicates that it is turned on, and the unhatched illumination indicates that it is turned off.
- the control unit 4 performs image analysis on the captured image to identify the lighting that is lit, and obtains the interval of the lighting that is lit. Specifically, the control unit 4 specifies the illumination 81a that is lit at the closest position at a predetermined distance (for example, several tens of meters away) from the vehicle position, and beyond the illumination 81a. Next, the lighting 81b that is lit next is specified on the side (the tip in the traveling direction). And the control part 4 calculates
- a predetermined distance for example, several tens of meters away

In other words, the control unit 4 determines whether the vehicle has reached before the tunnel exit where the adjustment of luminance and color tone should start.
- interval D is prescribed
- the interval D of the illumination that is lit is obtained from the illuminations 81a and 81b that are lit at a predetermined distance from the vehicle position, but is used to specify the illumination for obtaining the interval D.
- the “predetermined distance” is preferably set according to the vehicle speed. For example, it is preferable to obtain the distance D from the illumination that is lit at a position further away from the vehicle position by setting the “predetermined distance” longer as the vehicle speed increases. Furthermore, it is preferable to set a “predetermined value” for determining the interval D in accordance with the setting of the “predetermined distance” according to the vehicle speed. For example, as the vehicle speed increases, the interval D is obtained from the illumination that is lit at a position further away from the vehicle position, and thus the obtained interval D tends to be smaller.
- the “value” is also preferably reduced.
- control unit 4 starts adjusting the luminance and color tone of the display image when the interval D obtained as described above becomes equal to or less than a predetermined value.

For example, when the weather near the tunnel exit is clear, the control unit 4 increases the brightness of the display image or increases the saturation of the display image, compared to when the weather near the tunnel exit is cloudy or rainy. Increase the size or lighten the display image. Further, for example, when the time to reach the tunnel exit is morning or noon time, the control unit 4 sets the brightness of the display image more than when the time to reach the tunnel exit is night or evening time. The display image is enlarged, the saturation of the display image is increased, or the display image is lightened.

Because there is. For example, when the weather near the tunnel exit is clear, the lighting interval near the tunnel exit tends to be shorter than when the weather near the tunnel exit is cloudy or rainy.

Description
本発明は、情報を表示する技術に関する。
The present invention relates to a technique for displaying information.
従来から、ナビゲーション装置などにおいて、外界の状況などに応じて表示部の表示形態を変化させる技術が提案されている。例えば、特許文献1には、運転者において表示が煩わしくなるのを防止すべく、トンネルの入口手前から表示部の減光を開始し、トンネルの出口手前から表示部の増光を開始する技術が提案されている。当該技術では、車速及びトンネルの属性(地図データとして予め記憶された、トンネル内の明るさ)に基づいて、表示部の増光タイミングを算出している。つまり、表示部の増光を開始するトンネル出口手前を求めている。
Conventionally, a technique for changing a display form of a display unit in a navigation device or the like according to an external environment or the like has been proposed. For example, Patent Document 1 proposes a technique for starting the dimming of the display unit just before the entrance of the tunnel and starting the dimming of the display unit before the exit of the tunnel in order to prevent the driver from having troublesome display. Has been. In this technique, the brightness increase timing of the display unit is calculated based on the vehicle speed and the tunnel attribute (brightness in the tunnel stored in advance as map data). That is, it is required to be near the tunnel exit where the brightening of the display unit starts.
トンネル内では、出入口付近の天候や時間帯などの種々の状況に応じて明るさが変化される傾向にある。例えば、点灯させる照明の数(言い換えると点灯させる照明の間隔)などが変化される。そのため、上記した特許文献1に記載された技術においてトンネルの属性として記憶されたトンネル内の明るさは、実際のトンネル内の明るさと一致しない傾向にあると言える。したがって、特許文献1に記載された技術では、表示部を増光させるべきトンネル出口手前を適切に求めることは困難であると考えられる。
In the tunnel, the brightness tends to change according to various conditions such as the weather and time zone near the entrance. For example, the number of illuminations to be lit (in other words, the interval between illuminations to be lit) is changed. Therefore, it can be said that the brightness in the tunnel stored as the tunnel attribute in the technique described in Patent Document 1 described above tends not to match the actual brightness in the tunnel. Therefore, with the technique described in Patent Document 1, it is considered difficult to appropriately obtain the position before the tunnel exit where the display unit should be brightened.
ところで、照度センサにより前方の明るさを検出し、検出された明るさに基づいて、表示部の輝度などを調整すべきトンネルの出口手前を求める方法が考えられる。しかしながら、トンネル内では照明が間隔を置いて設置されていることから、トンネル内の走行中においては周囲や前方の明るさが大きく変化するため、この方法でも、輝度などを調整すべきトンネル出口手前を適切に求めることは困難であると考えられる。
By the way, it is conceivable to detect the front brightness by the illuminance sensor and obtain the front side of the tunnel exit where the brightness of the display unit should be adjusted based on the detected brightness. However, since the lights are installed at intervals in the tunnel, the brightness of the surroundings and the front changes greatly during traveling in the tunnel. It is considered difficult to appropriately determine

上記の表示装置は、トンネル内を移動中の移動体の進行方向に連続して設置された照明のうち、点灯中の照明に基づいて、表示部に表示させる画像(表示画像)の輝度や色調を調整する。トンネル内では、通常、トンネルの出口付近と、入口付近及び出口付近を除いた範囲とでは、点灯させる照明の数(言い換えると点灯させる照明の間隔)などが異なる傾向にある。そのため、表示制御手段は、このような傾向を考慮して、点灯中の照明に基づいてトンネルの出口手前を判断して、輝度や色調の調整を行う。これにより、輝度や色調の調整を行うべきトンネルの出口手前を適切に求めて、トンネルの出口付近において適切なタイミングで輝度や色調の調整を行うことが可能となる。よって、トンネルの出口付近において、ユーザが表示画像を眩しく感じたりする等の視認性の悪化を効果的に抑制することが可能となる。
The display device described above is based on the illumination that is lit among the illuminations that are continuously installed in the traveling direction of the moving object that is moving in the tunnel, and the brightness and color tone of the image (display image) displayed on the display unit. Adjust. In a tunnel, the number of illuminations to be lit (in other words, the interval between illuminations to be lit) tends to be different between the vicinity of the tunnel exit and the range excluding the entrance and the vicinity of the exit. For this reason, the display control means considers such a tendency and determines the position immediately before the exit of the tunnel based on the lighting that is lit, and adjusts the luminance and color tone. Accordingly, it is possible to appropriately obtain the position before the tunnel exit where the brightness and color tone should be adjusted, and to adjust the brightness and color tone at an appropriate timing in the vicinity of the tunnel exit.

The lighting interval near the exit of the tunnel tends to be different from the lighting interval in the range excluding near the entrance and near the exit. For this reason, the display control means considers such a tendency and determines the position just before the exit of the tunnel based on the interval of the lighting that is lit, and adjusts the brightness and the color tone. This makes it possible to adjust brightness and color tone at a more appropriate timing near the exit of the tunnel.

Preferably, in the above display device, the display control means adjusts the luminance and / or the color tone when the interval of the lighting during lighting becomes a predetermined value or less. This is because the lighting interval near the exit of the tunnel tends to be shorter than the interval of lighting during the range excluding the vicinity of the entrance and the vicinity of the exit.

制御部4は、基本的には、車両がトンネルに突入する際やトンネルから脱出する際に、ヘッドアップディスプレイ2による表示画像の視認性の悪化を抑制するべく、表示画像の輝度や色調を調整する制御を行う。具体的には、制御部4は、トンネルの入口手前において、段階的又は連続的に表示画像の輝度や色調を調整する。例えば、制御部4は、表示画像の輝度を低減させたり、表示画像の彩度を低減させたり、表示画像を暗色化させたりする制御を行う。また、制御部4は、トンネルの出口手前において、段階的又は連続的に表示画像の輝度や色調を調整する。例えば、制御部4は、表示画像の輝度を増加させたり、表示画像の彩度を増加させたり、表示画像を明色化させたりする制御を行う。このようにすることで、ユーザが表示画像を眩しく感じたりする等の視認性の悪化を抑制することが可能となる。
The control unit 4 basically adjusts the brightness and color tone of the display image so as to suppress the deterioration of the visibility of the display image by the head-up display 2 when the vehicle enters the tunnel or escapes from the tunnel. Control. Specifically, the control unit 4 adjusts the luminance and color tone of the display image stepwise or continuously before entering the tunnel. For example, the control unit 4 performs control to reduce the luminance of the display image, reduce the saturation of the display image, or darken the display image. Further, the control unit 4 adjusts the luminance and color tone of the display image stepwise or continuously before the exit of the tunnel. For example, the control unit 4 performs control to increase the brightness of the display image, increase the saturation of the display image, or lighten the display image. By doing in this way, it becomes possible to suppress deterioration of visibility, such as a user feeling a dazzling display image.
ところで、車両がトンネルに突入する前においては、ナビゲーション装置1内のGPS受信機18が受信した位置情報などに基づいて、車両がトンネルに突入するタイミングなどを適切に求めることができる。そのため、トンネルに突入する際には、輝度や色調の調整を行うべきタイミングを適切に求めることができると言える。つまり、輝度や色調の調整を行うべきトンネルの入口手前を適切に求めることができると言える。一方で、車両がトンネル内を走行している際には、ナビゲーション装置1内のGPS受信機18に電波が届きにくいため、トンネル内では車両の位置を適切に求めることが困難になる。そのため、トンネルを脱出する際には、輝度や色調の調整を行うべきタイミングを適切に求めることは困難であると言える。つまり、輝度や色調の調整を行うべきトンネルの出口手前を適切に求めることは困難であると言える。なお、本明細書では、「トンネルの出口手前」は、表示画像の視認性の悪化を抑制するために輝度や色調の調整を行うべきトンネル内の出口付近の位置を意味するものとする。
By the way, before the vehicle enters the tunnel, the timing at which the vehicle enters the tunnel can be appropriately determined based on the position information received by the GPS receiver 18 in the navigation device 1. Therefore, when entering a tunnel, it can be said that the timing for adjusting the luminance and the color tone can be appropriately obtained. In other words, it can be said that the position just before the entrance of the tunnel where the brightness and color tone should be adjusted can be obtained appropriately. On the other hand, when the vehicle is traveling in the tunnel, it is difficult for radio waves to reach the GPS receiver 18 in the navigation device 1, and it is difficult to appropriately determine the position of the vehicle in the tunnel. Therefore, when exiting the tunnel, it can be said that it is difficult to appropriately determine the timing for adjusting the luminance and color tone. In other words, it can be said that it is difficult to appropriately determine the position just before the exit of the tunnel where the brightness and color tone should be adjusted. In the present specification, “before the tunnel exit” means a position in the vicinity of the exit in the tunnel where brightness and color tone should be adjusted in order to suppress deterioration in the visibility of the display image.
ここで、照度センサにより前方の明るさを検出し、検出された明るさに基づいて、輝度や色調の調整を行うべきトンネルの出口手前を求める方法が考えられる。しかしながら、この方法では、トンネルの出口手前を適切に求めることは困難であると言える。というのは、トンネル内では照明が間隔を置いて設置されていることから、トンネル内の走行中においては周囲や前方の明るさが大きく変化するからである。また、トンネルの出口付近では、照明の設置間隔が短くなる傾向にあるからである。
Here, a method of detecting the front brightness with an illuminance sensor and obtaining the front side of the tunnel exit where the brightness and color tone should be adjusted based on the detected brightness is conceivable. However, with this method, it can be said that it is difficult to appropriately determine the position just before the tunnel exit. This is because the lighting in the tunnel is installed at intervals, so that the brightness of the surroundings and the front changes greatly during traveling in the tunnel. Moreover, it is because the installation space | interval of illumination tends to become short in the exit of a tunnel.
以上のことから、本実施例では、制御部4は、輝度や色調の調整を行うべきトンネルの出口手前を適切に求めるための処理を行う。本実施例では、制御部4は、カメラ6によって撮影された撮影画像を解析することで、トンネル内を移動中の車両の進行方向に連続して設置された照明のうちで点灯中の照明の間隔を求め、当該間隔に基づいてトンネルの出口手前を求める(つまりトンネル出口の接近を検出する)。具体的には、制御部4は、点灯中の照明の間隔が所定値以下となった際に、輝度や色調の調整を行うべきトンネルの出口手前に車両が達したものとして、輝度や色調の調整を開始する。
From the above, in the present embodiment, the control unit 4 performs a process for appropriately obtaining the position just before the tunnel exit where the brightness and the color tone should be adjusted. In the present embodiment, the control unit 4 analyzes the captured image captured by the camera 6, so that the illumination of the illumination that is lit among the illuminations that are continuously installed in the traveling direction of the vehicle moving in the tunnel is performed. An interval is obtained, and the position just before the tunnel exit is obtained based on the interval (that is, the approach of the tunnel exit is detected). Specifically, the control unit 4 determines that the brightness and color tone of the vehicle has reached the exit of the tunnel where the brightness and color tone should be adjusted when the interval of lighting during lighting becomes a predetermined value or less. Start adjustment.
次に、図4及び図5を参照して、本実施例に係る表示制御方法について具体的に説明する。
Next, the display control method according to the present embodiment will be described in detail with reference to FIGS.

図4中の範囲71、72に示すように、トンネルの出口付近(入口付近も同様である)では、通常、トンネルの入口付近及び出口付近を除いた範囲よりも、多くの数の照明が点灯される。つまり、出口付近では、入口付近及び出口付近を除いた範囲よりも、点灯中の照明の数が多くなる傾向にある。また、出口付近(入口付近も同様である)では、入口付近及び出口付近を除いた範囲よりも、照明の設置間隔が短くされる場合がある(全てのトンネルでそうなっているわけではない)。以上のことから、出口付近での点灯中の照明の間隔d2は、入口付近及び出口付近を除いた範囲での点灯中の照明の間隔d1よりも短くなる傾向にある。したがって、本実施例では、このような点灯中の照明の間隔に基づいて、トンネルの出口手前を判断している。
As shown in the ranges 71 and 72 in FIG. 4, in the vicinity of the tunnel exit (the same applies to the vicinity of the entrance), usually, a larger number of lights are lit than the range except for the vicinity of the tunnel entrance and the exit. Is done. That is, in the vicinity of the exit, there is a tendency that the number of lighting lights is larger than the range except for the vicinity of the entrance and the vicinity of the exit. Further, in the vicinity of the exit (the same applies to the vicinity of the entrance), the lighting installation interval may be shorter than the range excluding the vicinity of the entrance and the vicinity of the exit (not all tunnels). From the above, the lighting interval d2 in the vicinity of the exit tends to be shorter than the lighting interval d1 in the range excluding the vicinity of the entrance and the vicinity of the exit. Therefore, in this embodiment, the position just before the exit of the tunnel is determined based on the interval of the lighting during lighting.
図5は、点灯中の照明の間隔を求める方法を説明するための図を示している。図5は、カメラ6によって撮影された撮影画像(車両の進行方向における風景の画像)の一例を示している。図5では、破線領域81、82内に、トンネル内において上方に設置された照明を示している。ハッチングされた照明は点灯中であることを示しており、ハッチングされていない照明は消灯中であることを示している。
FIG. 5 shows a diagram for explaining a method for obtaining the interval of lighting during lighting. FIG. 5 shows an example of a captured image (landscape image in the traveling direction of the vehicle) captured by the camera 6. In FIG. 5, the illumination installed upward in the tunnel is shown in the broken line areas 81 and 82. The hatched illumination indicates that it is turned on, and the unhatched illumination indicates that it is turned off.
本実施例では、制御部4は、撮影画像を画像解析することで、点灯中の照明を特定し、点灯中の照明の間隔を求める。具体的には、制御部4は、自車位置から所定距離先(例えば数十メートル先)の位置において、最も手前側の位置で点灯している照明81aを特定すると共に、その照明81aの向こう側(進行方向の先)において次に点灯している照明81bを特定する。そして、制御部4は、特定した照明81aと照明81bとの間隔Dを求める。制御部4は、トンネル内の走行中において、このような間隔Dを繰り返し求め、求めた間隔Dが所定値以下であるか否かを判定する。こうすることで、制御部4は、表示画像の視認性の悪化を抑制するために輝度や色調の調整を開始すべきタイミングを判断する。言い換えると、制御部4は、輝度や色調の調整を開始すべきトンネル出口手前に、車両が達したかを判断する。
In the present embodiment, the control unit 4 performs image analysis on the captured image to identify the lighting that is lit, and obtains the interval of the lighting that is lit. Specifically, the control unit 4 specifies the illumination 81a that is lit at the closest position at a predetermined distance (for example, several tens of meters away) from the vehicle position, and beyond the illumination 81a. Next, the lighting 81b that is lit next is specified on the side (the tip in the traveling direction). And the control part 4 calculates | requires the space | interval D of the specified illumination 81a and the illumination 81b. The controller 4 repeatedly obtains such an interval D during traveling in the tunnel, and determines whether or not the obtained interval D is equal to or less than a predetermined value. By doing so, the control unit 4 determines the timing at which adjustment of luminance and color tone should be started in order to suppress deterioration in the visibility of the display image. In other words, the control unit 4 determines whether the vehicle has reached before the tunnel exit where the adjustment of luminance and color tone should start.
なお、図5では、照明81aにおける手前側のエッジと照明81bにおける手前側のエッジとによって間隔Dを規定しているが、このように間隔Dを規定することに限定はされない。また、自車両の右側の上方の照明81a、81b(つまり破線領域81内の照明)から間隔Dを求めることに限定はされず、自車両の左側の上方の照明(つまり破線領域82内の照明)から間隔Dを求めても良い。また、間隔Dとしては、撮影画像上での照明81aと照明81bとの間の長さを用いることに限定はされず、このような撮影画像上での長さを実際の照明81aと照明81bとの間の長さ(つまり照明81aと照明81bとの設置間隔)に換算したものを用いても良い。
In addition, in FIG. 5, although the space | interval D is prescribed | regulated by the near edge in the illumination 81a and the near edge in the illumination 81b, it is not limited to defining the interval D in this way. Further, it is not limited to obtaining the distance D from the upper lights 81a and 81b on the right side of the own vehicle (that is, the lights in the broken line area 81), and the upper illumination on the left side of the own vehicle (that is, the lights in the broken line area 82). ) To obtain the distance D. Further, the distance D is not limited to using the length between the illumination 81a and the illumination 81b on the captured image, and the length on the captured image is not limited to the actual illumination 81a and the illumination 81b. What is converted into the length between the two (that is, the installation interval between the illumination 81a and the illumination 81b) may be used.
更に、上記では、点灯中の照明の間隔Dを、自車位置から所定距離先の位置において点灯している照明81a、81bにより求めたが、間隔Dを求めるための照明を特定するために用いる「所定距離」を、車速に応じて設定することが好ましい。例えば、車速が速いほど「所定距離」を長く設定することで、自車位置からより離れた位置において点灯している照明から間隔Dを求めることが好ましい。更に、このような「所定距離」の設定に合わせて、間隔Dを判定するための「所定値」も車速に応じて設定することが好ましい。例えば、車速が速いほど、自車位置からより離れた位置において点灯している照明から間隔Dが求められるため、求められる間隔Dも小さくなる傾向にあるので、間隔Dを判定するための「所定値」も小さくすることが好ましい。
Further, in the above description, the interval D of the illumination that is lit is obtained from the illuminations 81a and 81b that are lit at a predetermined distance from the vehicle position, but is used to specify the illumination for obtaining the interval D. The “predetermined distance” is preferably set according to the vehicle speed. For example, it is preferable to obtain the distance D from the illumination that is lit at a position further away from the vehicle position by setting the “predetermined distance” longer as the vehicle speed increases. Furthermore, it is preferable to set a “predetermined value” for determining the interval D in accordance with the setting of the “predetermined distance” according to the vehicle speed. For example, as the vehicle speed increases, the interval D is obtained from the illumination that is lit at a position further away from the vehicle position, and thus the obtained interval D tends to be smaller. The “value” is also preferably reduced.
ここで、本実施例では、制御部4は、上記のように求められた間隔Dが所定値以下となった際に、表示画像の輝度や色調の調整を開始する。具体的には、制御部4は、表示画像の輝度を増加させる制御、表示画像の彩度を増加させる制御、及び表示画像を明色化させる制御のうちの少なくともいずれかを実行する。
Here, in the present embodiment, the control unit 4 starts adjusting the luminance and color tone of the display image when the interval D obtained as described above becomes equal to or less than a predetermined value. Specifically, the control unit 4 executes at least one of control for increasing the luminance of the display image, control for increasing the saturation of the display image, and control for brightening the display image.
この場合、本実施例では、制御部4は、トンネル内において外界の外光度合いを推定して、表示画像の輝度や色調の調整を行う。具体的には、制御部4は、トンネル出口付近の天気、及び/又は、車両がトンネル出口に到達する時刻に応じて、輝度や色調を調整する度合いを設定する。例えば、制御部4は、トンネル出口付近の天気が晴れである場合には、トンネル出口付近の天気が曇りや雨である場合よりも、表示画像の輝度を大きくしたり、表示画像の彩度を大きくしたり、表示画像を明色化させたりする。また、例えば、制御部4は、トンネル出口に到達する時刻が朝や昼の時刻である場合には、トンネル出口に到達する時刻が夜や夕方の時刻である場合よりも、表示画像の輝度を大きくしたり、表示画像の彩度を大きくしたり、表示画像を明色化させたりする。
In this case, in this embodiment, the control unit 4 estimates the degree of external light in the tunnel and adjusts the luminance and color tone of the display image. Specifically, the control unit 4 sets the degree of adjusting the luminance and color tone according to the weather near the tunnel exit and / or the time when the vehicle reaches the tunnel exit. For example, when the weather near the tunnel exit is clear, the control unit 4 increases the brightness of the display image or increases the saturation of the display image, compared to when the weather near the tunnel exit is cloudy or rainy. Increase the size or lighten the display image. Further, for example, when the time to reach the tunnel exit is morning or noon time, the control unit 4 sets the brightness of the display image more than when the time to reach the tunnel exit is night or evening time. The display image is enlarged, the saturation of the display image is increased, or the display image is lightened.
なお、制御部4は、ナビゲーション装置1から、このようなトンネル出口付近の天気の情報やトンネル出口に到達する時刻を取得する。例えば、ナビゲーション装置1は、通信装置38によってトンネル出口付近の天気の情報を受信すると共に、地図データとして記憶されたトンネルの距離及び自立測位装置10によって検出された車速に基づいて、車両がトンネル出口に到達する時刻を求める。基本的には、トンネル内では通信装置38に電波が届きにくいため、ナビゲーション装置1は、車両がトンネルに突入する前に通信装置38よりトンネル出口付近の天気の情報を受信しておき、当該天気の情報を制御部4に供給する。
Note that the control unit 4 acquires the weather information near the tunnel exit and the time to reach the tunnel exit from the navigation device 1. For example, the navigation device 1 receives the weather information in the vicinity of the tunnel exit by the communication device 38, and the vehicle is connected to the tunnel exit based on the distance of the tunnel stored as map data and the vehicle speed detected by the autonomous positioning device 10. Find the time to reach. Basically, it is difficult for radio waves to reach the communication device 38 in the tunnel. Therefore, the navigation device 1 receives weather information in the vicinity of the tunnel exit from the communication device 38 before the vehicle enters the tunnel. Is supplied to the control unit 4.
更に、本実施例では、制御部4は、上記したようなトンネル出口付近の天気やトンネル出口に到達する時刻の代わりに、若しくはトンネル出口付近の天気やトンネル出口に到達する時刻に加えて、トンネルの出口付近における点灯中の照明の間隔に基づいて、表示画像の輝度や色調を調整する度合いを設定する。こうするのは、トンネル出口付近の天気や時刻やトンネル出口が向いている方角などに応じて、トンネルの出口付近において点灯させる照明の数(言い換えると点灯させる照明の間隔)が設定される傾向にあるからである。例えば、トンネル出口付近の天気が晴れである場合には、トンネル出口付近の天気が曇りや雨である場合よりも、トンネル出口付近における点灯中の照明の間隔が短くなる傾向にある。また、例えば、朝や昼の時刻であるである場合には、夜や夕方の時刻である場合よりも、トンネル出口付近における点灯中の照明の間隔が短くなる傾向にある。また、例えば、トンネル出口が南側を向いている場合には、トンネル出口が北側を向いている場合よりも、トンネル出口付近における点灯中の照明の間隔が短くなる傾向にある。制御部4は、トンネル出口付近における点灯中の照明の間隔が短い場合には、点灯中の照明の間隔が長い場合よりも、表示画像の輝度を大きくしたり、表示画像の彩度を大きくしたり、表示画像を明色化させたりする。
Further, in this embodiment, the control unit 4 does not use the weather near the tunnel exit or the time to reach the tunnel exit as described above, or in addition to the weather near the tunnel exit or the time to reach the tunnel exit. The degree of adjustment of the brightness and color tone of the display image is set based on the interval of the lighting that is lit in the vicinity of the exit. This is because the number of lights to be lit near the tunnel exit (in other words, the interval between the lights to be lit) tends to be set according to the weather and time near the tunnel exit and the direction the tunnel exit is facing. Because there is. For example, when the weather near the tunnel exit is clear, the lighting interval near the tunnel exit tends to be shorter than when the weather near the tunnel exit is cloudy or rainy. In addition, for example, when it is morning or noon time, the interval of lighting during lighting near the tunnel exit tends to be shorter than when it is night or evening time. Further, for example, when the tunnel exit faces the south side, the interval between the lightings in the vicinity of the tunnel exit tends to be shorter than when the tunnel exit faces the north side. The control unit 4 increases the brightness of the display image or increases the saturation of the display image when the interval between the lightings in the vicinity of the tunnel exit is short compared to when the lighting interval is long. Or lighten the display image.
以上説明した本実施例に係る表示制御方法によれば、トンネル内の点灯中の照明の間隔を用いることで、輝度や色調の調整を行うべきトンネルの出口手前を適切に求めることができる。よって、トンネルの出口付近において適切なタイミングで輝度や色調の調整を行うことができ、ユーザが表示画像を眩しく感じたりする等の視認性の悪化を効果的に抑制することが可能となる。
According to the display control method according to the present embodiment described above, it is possible to appropriately obtain the position just before the exit of the tunnel where the brightness and color tone should be adjusted by using the lighting interval in the tunnel. Therefore, brightness and color tone can be adjusted at an appropriate timing in the vicinity of the exit of the tunnel, and deterioration of visibility such as a user feeling a dazzling display image can be effectively suppressed.

まず、ステップS101では、制御部4は、車両がトンネルに突入するか否かを判定する。つまり、車両の前方にトンネルが存在するか否かを判定する。制御部4は、ナビゲーション装置1から、地図データに記憶されたトンネルの情報(具体的にはトンネル入口の位置座標)や、GPS受信機18が受信した自車位置などの情報を取得して、このような判定を行う。車両がトンネルに突入する場合(ステップS101:Yes)、つまり車両の前方にトンネルが存在する場合、処理はステップS102に進む。これに対して、車両がトンネルに突入しない場合(ステップS101:No)、つまり車両の前方にトンネルが存在しない場合、処理は終了する。
First, in step S101, the control unit 4 determines whether or not the vehicle enters the tunnel. That is, it is determined whether a tunnel exists in front of the vehicle. The control unit 4 acquires information such as the tunnel information (specifically, the position coordinates of the tunnel entrance) stored in the map data and the vehicle position received by the GPS receiver 18 from the navigation device 1, Such a determination is performed. If the vehicle enters the tunnel (step S101: Yes), that is, if a tunnel exists in front of the vehicle, the process proceeds to step S102. On the other hand, when the vehicle does not enter the tunnel (step S101: No), that is, when there is no tunnel in front of the vehicle, the process ends.
ステップS102では、制御部4は、ナビゲーション装置1から、トンネル出口付近の情報を取得する。具体的には、制御部4は、トンネル出口付近の天気の情報やトンネル出口に到達する時刻を取得する。ナビゲーション装置1は、通信装置38によってトンネル出口付近の天気の情報を受信すると共に、地図データとして記憶されたトンネルの距離及び自立測位装置10によって検出された車速に基づいて、車両がトンネル出口に到達する時刻を求める(時刻を求めることに限定はされず、時間帯を求めることとしても良い)。そして、処理はステップS103に進む。
In step S102, the control unit 4 acquires information about the vicinity of the tunnel exit from the navigation device 1. Specifically, the control unit 4 acquires weather information in the vicinity of the tunnel exit and the time to reach the tunnel exit. The navigation device 1 receives the weather information in the vicinity of the tunnel exit by the communication device 38, and the vehicle reaches the tunnel exit based on the distance of the tunnel stored as map data and the vehicle speed detected by the autonomous positioning device 10. (The time is not limited, and the time zone may be obtained). Then, the process proceeds to step S103.
ステップS103では、制御部4は、車両がトンネルに突入したか否かを判定する。制御部4は、ナビゲーション装置1から取得された、トンネルの情報(具体的にはトンネル入口の位置座標)や自車位置の情報などに基づいて、このような判定を行う。車両がトンネルに突入した場合(ステップS103:Yes)、処理はステップS104に進み、車両がトンネルに突入していない場合(ステップS103:No)、処理はステップS102に戻る。
In step S103, the control unit 4 determines whether or not the vehicle has entered the tunnel. The control unit 4 makes such a determination based on the tunnel information (specifically, the position coordinates of the tunnel entrance), the vehicle position information, and the like acquired from the navigation device 1. If the vehicle has entered the tunnel (step S103: Yes), the process proceeds to step S104. If the vehicle has not entered the tunnel (step S103: No), the process returns to step S102.
ステップS104では、制御部4は、車両がトンネル入口付近を走行中でないか否かを判定する。例えば、制御部4は、車両がトンネルに突入してから走行した距離が所定距離以上となったか否かを判定する。トンネル入口付近を走行中でない場合(ステップS104:Yes)、処理はステップS105に進み、トンネル入口付近を走行中である場合(ステップS104:No)、処理はステップS104に戻る。
In step S104, the control unit 4 determines whether or not the vehicle is traveling near the tunnel entrance. For example, the control unit 4 determines whether the distance traveled since the vehicle entered the tunnel is equal to or greater than a predetermined distance. If the vehicle is not traveling near the tunnel entrance (step S104: Yes), the process proceeds to step S105. If the vehicle is traveling near the tunnel entrance (step S104: No), the process returns to step S104.
ステップS105では、制御部4は、ナビゲーション装置1から、自立測位装置10によって検出された車速を取得する。そして、処理はステップS106に進む。
In step S105, the control unit 4 acquires the vehicle speed detected by the autonomous positioning device 10 from the navigation device 1. Then, the process proceeds to step S106.
ステップS106では、制御部4は、カメラ6によって撮影された撮影画像を取得し、当該撮影画像に対して画像解析を実行する。具体的には、制御部4は、撮影画像を画像解析することで、自車位置の所定距離先の位置において、最も手前側の位置で点灯している照明を特定すると共に、当該照明の向こう側(進行方向の先)において次に点灯している照明を特定する。この場合、制御部4は、ステップS105で取得された車速に応じて、照明を特定するために用いる所定距離を設定する。具体的には、制御部4は、車速が早いほど、所定距離を長くする。以上のステップS106の後、処理はステップS107に進む。
In step S106, the control unit 4 acquires a captured image captured by the camera 6, and executes image analysis on the captured image. Specifically, the control unit 4 performs image analysis on the captured image to identify the illumination that is lit at the nearest position at a position a predetermined distance ahead of the host vehicle position, and beyond the illumination. The next lighting on the side (the tip in the traveling direction) is specified. In this case, the control part 4 sets the predetermined distance used in order to specify illumination according to the vehicle speed acquired by step S105. Specifically, the control unit 4 increases the predetermined distance as the vehicle speed increases. After step S106 described above, the process proceeds to step S107.
ステップS107では、制御部4は、ステップS106において画像解析により特定された点灯中の照明の間隔を算出する。この場合、当該間隔として、撮影画像上での照明間の長さを用いても良いし、撮影画像上での照明間の長さを実際の照明間の距離(つまり照明の設置間隔)に換算したものを用いても良い。そして、処理はステップS108に進む。
In step S107, the control unit 4 calculates the interval of lighting during lighting specified by the image analysis in step S106. In this case, the length between the illuminations on the captured image may be used as the interval, or the length between the illuminations on the captured image is converted into the distance between the actual illuminations (that is, the installation interval of the illumination). You may use what you did. Then, the process proceeds to step S108.
ステップS108では、制御部4は、ステップS107で算出された間隔が所定値以下であるか否かを判定する。ここでは、制御部4は、間隔と所定値とを比較することで、表示画像の視認性の悪化を抑制するために輝度や色調の調整を行うべきトンネル出口手前に、車両が達したか否かを判定している。判定に用いる所定値は、基本的には、各トンネルの設計(例えば出口付近の照明間の間隔)などに応じて設定される。また、所定値は、車速に応じて変化される。具体的には、制御部4は、車速(ステップS105で取得された車速)が早いほど、所定値を小さくする。
In step S108, the control unit 4 determines whether or not the interval calculated in step S107 is a predetermined value or less. Here, the control unit 4 compares the interval with a predetermined value to determine whether or not the vehicle has reached before the tunnel exit where the brightness and color tone should be adjusted in order to suppress the deterioration of the visibility of the display image. Judging. The predetermined value used for the determination is basically set according to the design of each tunnel (for example, the interval between lights near the exit). Further, the predetermined value is changed according to the vehicle speed. Specifically, the control unit 4 decreases the predetermined value as the vehicle speed (the vehicle speed acquired in step S105) increases.
間隔が所定値以下である場合(ステップS108:Yes)、処理はステップS109に進み、間隔が所定値以下でない場合(ステップS108:No)、処理はステップS105に戻る。
If the interval is less than or equal to the predetermined value (step S108: Yes), the process proceeds to step S109. If the interval is not less than the predetermined value (step S108: No), the process returns to step S105.
ステップS109では、制御部4は、トンネルから脱出する際における視認性の悪化(ユーザが表示画像を眩しく感じたりする等)を抑制すべく、表示画像の輝度及び/又は色調の調整を行う。具体的には、制御部4は、表示画像の輝度を増加させる制御、表示画像の彩度を増加させる制御、及び表示画像を明色化させる制御のうちの少なくともいずれかを実行する。この場合、制御部4は、ステップS102で取得された、トンネル出口付近の天気及び/又は車両がトンネル出口に到達する時刻に応じて、輝度や色調を調整する度合いを設定する。また、制御部4は、トンネル出口付近の天気やトンネル出口に到達する時刻の代わりに、若しくはトンネル出口付近の天気やトンネル出口に到達する時刻に加えて、ステップS107で算出された点灯中の照明の間隔に応じて、輝度や色調を調整する度合いを設定する。1つの例では、このような各種のパレメータに応じて輝度や色調を調整する度合いを定めたテーブルを予め作成しておき、制御部4は、このようなテーブルを参照することで、表示画像の輝度や色調を調整する。以上のステップS109の後、処理はステップS110に進む。
In step S109, the control unit 4 adjusts the luminance and / or color tone of the display image in order to suppress deterioration in visibility when the user escapes from the tunnel (such as the user feeling the display image dazzling). Specifically, the control unit 4 executes at least one of control for increasing the luminance of the display image, control for increasing the saturation of the display image, and control for brightening the display image. In this case, the control unit 4 sets the degree of adjusting the brightness and color tone according to the weather near the tunnel exit and / or the time when the vehicle reaches the tunnel exit acquired in step S102. Further, the control unit 4 does not use the weather in the vicinity of the tunnel exit or the time to reach the tunnel exit, or in addition to the weather in the vicinity of the tunnel exit or the time to reach the tunnel exit, the lighting during lighting calculated in step S107. The degree of adjusting brightness and color tone is set according to the interval. In one example, a table that defines the degree of adjustment of luminance and color tone in accordance with such various parameters is created in advance, and the control unit 4 refers to such a table so that the display image is displayed. Adjust brightness and color tone. After step S109, the process proceeds to step S110.
ステップS110では、制御部4は、車両がトンネルを脱出したか否かを判定する。例えば、制御部4は、ナビゲーション装置1から取得された、トンネルの情報(具体的にはトンネル出口の位置座標)や、トンネル走行中に自立測位装置10によって検出された車速や加速度や角速度などに基づいて、このような判定を行う。車両がトンネルを脱出した場合(ステップS110:Yes)、処理は終了し、車両がトンネルを脱出していない場合(ステップS110:No)、処理はステップS105に戻る。
In step S110, the control unit 4 determines whether or not the vehicle has escaped from the tunnel. For example, the control unit 4 determines the tunnel information (specifically, the position coordinates of the tunnel exit) acquired from the navigation device 1, the vehicle speed, acceleration, angular velocity, etc. detected by the self-supporting positioning device 10 while traveling through the tunnel. Such a determination is made based on this. If the vehicle has escaped from the tunnel (step S110: Yes), the process ends. If the vehicle has not escaped from the tunnel (step S110: No), the process returns to step S105.
以上説明した処理フローによれば、トンネルの出口付近において適切なタイミングで輝度や色調の調整を行うことができ、ユーザが表示画像を眩しく感じたりする等の視認性の悪化を効果的に抑制することが可能となる。
According to the processing flow described above, brightness and color tone can be adjusted at an appropriate timing in the vicinity of the exit of the tunnel, and deterioration of visibility such as a user feeling a dazzling display image is effectively suppressed. It becomes possible.

上記では、トンネル内において自車両が走行する車線の上方に設けられた照明について、点灯中の照明の間隔を求める実施例を示したが(図5参照)、この代わりに、対向車線の上方に設けられた照明について、点灯中の照明の間隔を求めても良い。これは、対向車線におけるトンネル入口付近は、基本的には、自車両が走行する車線におけるトンネル出口付近に対応するため、対向車線における点灯中の照明の間隔によって、対向車線におけるトンネル入口付近を判定することで、自車両が走行する車線におけるトンネル出口手前を判断することができるからである。但し、対向車線に設けられた照明を用いる場合には、対向車線において点灯中の照明が平行に配列されていることが望ましい。 (Modification 1)
In the above, an example has been shown in which the interval between lightings is determined for the lighting provided above the lane in which the vehicle travels in the tunnel (see FIG. 5), but instead, above the opposite lane. You may obtain | require the space | interval of the lighting in lighting about the provided illumination. This is because the vicinity of the tunnel entrance in the opposite lane basically corresponds to the vicinity of the tunnel exit in the lane in which the host vehicle is traveling, so the vicinity of the tunnel entrance in the opposite lane is determined based on the lighting interval in the opposite lane. This is because it is possible to determine the position before the tunnel exit in the lane in which the host vehicle is traveling. However, in the case where the illumination provided in the oncoming lane is used, it is desirable that the lighting on the oncoming lane is arranged in parallel.
