Description
本開示は、前照灯配光制御装置及び前照灯配光制御方法に関する。 The present disclosure relates to a headlamp light distribution control device and a headlamp light distribution control method.
特許文献1に記載の車両用前照灯の配光制御方法及び配光制御装置は、前方車両に対する眩惑を防止することを目的の一つとする。前記した特許文献1の方法及び装置は、前記目的を達成すべく、前方車両の車両位置を検出し、検出された前方車両の車両位置に対応して複数の照明領域を選択的に減光する。 One of the purposes of the light distribution control method and light distribution control device for a vehicle headlamp described in Patent Document 1 is to prevent dazzling of a vehicle ahead. In order to achieve the above object, the method and device of Patent Document 1 described above detects the vehicle position of the preceding vehicle and selectively dims a plurality of illumination areas in accordance with the detected vehicle position of the preceding vehicle. .
しかしながら、上記した方法及び装置は、上記した前方車両の車両位置の検出を、撮像した前方車両の画像を分析することにより行う。前記画像の分析に要する時間に伴う時間的なずれに起因して、画像の分析を開始する時点では照射すべき照明領域であったものの、画像の分析を終了した時点では照射すべきでなくなった照明領域を照射することになり、前方車両に対する眩惑を防止することができないことがあった。あるいは前方車両位置の検出から照射までの制御系において遅れが生じる部分があった場合、照射すべきでなくなった照明領域を照射することになる虞も考えられる。 However, the method and device described above detect the vehicle position of the vehicle ahead by analyzing the captured image of the vehicle ahead. Due to the time lag associated with the time required to analyze the image, the illumination area was the one that should be illuminated when the image analysis started, but should not be illuminated when the image analysis was finished. Since the illumination area is illuminated, it may not be possible to prevent the vehicle ahead from being dazzled. Alternatively, if there is a delay in the control system from detection of the forward vehicle position to irradiation, there is a possibility that an illumination area that should no longer be irradiated may be irradiated.
本開示の目的は、自車両の視認性を確保しつつ、他車両の視認性を悪化させることを回避することができる前照灯配光制御装置及び前照灯配光制御方法を提供することにある。 An object of the present disclosure is to provide a headlamp light distribution control device and a headlamp light distribution control method that can avoid deteriorating the visibility of other vehicles while ensuring the visibility of one's own vehicle. It is in.
上記した課題を解決すべく、本開示に係る前照灯配光制御装置は、自車両の前方に存在する他車両の画像に基づき前記他車両の位置を検出する検出部と、前記検出された他車両の位置に基づき、遮光すべき領域である遮光領域を決定する第1の決定部と、前記決定された遮光領域に近接し、かつ前記遮光領域の光量に比して光量が大きくなるべき領域である複数の減光領域を決定する第2の決定部と、前記他車両における運転者の位置を推定する推定部と、前記複数の減光領域のうち、前記推定された運転者の位置により近い一の減光領域の光量が、前記一の減光領域以外の他の減光領域の光量より小さくなるように前照灯の照射を制御する制御部と、を含む。 In order to solve the above-mentioned problems, a headlamp light distribution control device according to the present disclosure includes a detection unit that detects the position of another vehicle based on an image of the other vehicle existing in front of the own vehicle; a first determining unit that determines a light-shielding area that is an area to be light-shielded based on the position of another vehicle; a second determining unit that determines a plurality of dimming areas that are regions; an estimating unit that estimates the position of the driver in the other vehicle; and a second determining unit that estimates the position of the driver in the other vehicle; and a control unit that controls the irradiation of the headlamp so that the amount of light in one dimming region that is closer to the one is smaller than the amount of light in other dimming regions other than the one dimming region.
本開示に係る前照灯配光制御装置によれば、自車両の視認性を確保しつつ、他車両の視認性を悪化させることを回避することができる。 According to the headlamp light distribution control device according to the present disclosure, it is possible to avoid deteriorating the visibility of other vehicles while ensuring the visibility of the own vehicle.

〈実施形態1の機能〉
図1は、実施形態1の前照灯配光制御装置ZHSの機能ブロック図である。実施形態1の前照灯配光制御装置ZHSの機能について、図1を参照して説明する。<Functions of Embodiment 1>
FIG. 1 is a functional block diagram of a headlamp light distribution control device ZHS according to the first embodiment. The functions of the headlamp light distribution control device ZHS of Embodiment 1 will be described with reference to FIG. 1.
実施形態1の前照灯配光制御装置ZHSは、自車両の前方に存在する他車両としての前方車両ZS及び/あるいは対向車両TSの状況に応じて、前照灯ZTの照射を制御すべく、図1に示されるように、撮像部SAと、検出部KEと、第1の決定部KE1と、第2の決定部KE2と、推定部SUと、制御部SEと、を含む。図1では撮像部SAが前照灯配光制御装置ZHSに含まれているが、前照灯配光制御装置ZHSの外部に設けられた撮像部SAから信号を受領するようにしてもよい。 The headlamp light distribution control device ZHS of Embodiment 1 is designed to control the irradiation of the headlamp ZT according to the situation of the front vehicle ZS and/or the oncoming vehicle TS as other vehicles existing in front of the host vehicle. , as shown in FIG. 1, includes an imaging section SA, a detection section KE, a first determination section KE1, a second determination section KE2, an estimation section SU, and a control section SE. In FIG. 1, the imaging section SA is included in the headlamp light distribution control device ZHS, but the signal may be received from the imaging section SA provided outside the headlamp light distribution control device ZHS.
検出部KEは、「検出部」に対応し、第1の決定部KE1は、「第1の決定部」に対応し、第2の決定部KE2は、「第2の決定部」に対応し、推定部SUは、「推定部」に対応し、制御部SEは、「制御部SE」に対応する。 The detection unit KE corresponds to a “detection unit”, the first determination unit KE1 corresponds to a “first determination unit”, and the second determination unit KE2 corresponds to a “second determination unit”. , the estimating unit SU corresponds to the “estimating unit”, and the control unit SE corresponds to the “control unit SE”.
図2は、実施形態1の自車両JSと自車両の前方に存在する他車両との関係を示す。 FIG. 2 shows the relationship between the own vehicle JS of the first embodiment and other vehicles existing in front of the own vehicle.
「他車両」とは、自車両JS以外の車両をいう。他車両は、図2に示されるように、例えば、自車両JSの前方に存在し、かつ、自車両JSが走行する道路DR1と同一の道路DR1を、自車両JSの走行方向と同一の方向に走行する前方車両ZS、及び/あるいは、自車両JSの前方に存在し、かつ、自車両JSが走行する道路DR1に対向する道路DR2を、自車両JSの走行方向とは反対の方向に走行する対向車両TSである。 "Other vehicles" refers to vehicles other than the own vehicle JS. As shown in FIG. 2, for example, the other vehicle is located in front of the host vehicle JS and travels along the same road DR1 as the road DR1 on which the host vehicle JS travels, in the same direction as the travel direction of the host vehicle JS. A vehicle ahead of the vehicle ZS and/or a road DR2 that is located in front of the vehicle JS and is opposite to the road DR1 on which the vehicle JS is traveling in a direction opposite to the direction of travel of the vehicle JS. This is the oncoming vehicle TS.
以下では、説明及び理解を容易にすべく、表記「他車両ZS、TS」により、前方車両ZS及び/あるいは対向車両TSの両者/あるいは一方を示すことがある。 Below, in order to facilitate explanation and understanding, the notation "other vehicles ZS, TS" may refer to both/or one of the forward vehicle ZS and/or the oncoming vehicle TS.
図1に戻り、撮像部SAは、他車両ZS、TSの画像を撮像する。撮像部SAは、例えば、カメラから構成される。 Returning to FIG. 1, the imaging unit SA captures images of other vehicles ZS and TS. The imaging unit SA is composed of, for example, a camera.
検出部KEは、撮像部SAにより撮像された他車両ZS、TSの画像に基づき、他車両ZS、TSの位置を検出する。 The detection unit KE detects the positions of the other vehicles ZS and TS based on the images of the other vehicles ZS and TS captured by the imaging unit SA.
第1の決定部KE1は、検出部KEにより検出された他車両ZS、TSの位置に基づき、図2に示されるように、例えば、他車両ZS、TSの運転者の視認性を悪化させることを防止するために遮光すべき領域である前方車両遮光領域SZS及び対向車両遮光領域STSを決定する。前方車両遮光領域SZSは、図2に示されるように、主に、前方車両ZSの進行方向の前方の領域及び進行方向の後方の領域である。対向車両遮光領域STSは、図2に示されるように、主に、対向車両TSの進行方向の斜め前方の領域である。 Based on the positions of the other vehicles ZS and TS detected by the detection unit KE, the first determination unit KE1 determines, for example, that the driver's visibility of the other vehicles ZS and TS is deteriorated, as shown in FIG. A forward vehicle light shielding region SZS and an oncoming vehicle light shielding region STS, which are regions to be shielded from light in order to prevent this, are determined. As shown in FIG. 2, the front vehicle light-shielding region SZS is mainly a region in front of the forward vehicle ZS in the traveling direction and a region behind the forward vehicle ZS in the traveling direction. As shown in FIG. 2, the oncoming vehicle light shielding region STS is mainly a region diagonally in front of the oncoming vehicle TS in the traveling direction.
第2の決定部KE2は、前方車両ZSについて、図2に示されるように、第1の決定部KE1により決定された前方車両遮光領域SZSに近接する前方車両左減光領域GZS(H)及び前方車両右減光領域GZS(M)を決定する。 As shown in FIG. 2, the second determination unit KE2 determines, for the front vehicle ZS, a front vehicle left light attenuation area GZS(H) and Determine the front vehicle right light attenuation area GZS(M).
前方車両左減光領域GZS(H)の光量である前方車両左光量IZS(H)及び前方車両右減光領域GZS(M)の光量である前方車両右光量IZS(M)は、制御部SEによる前照灯ZTの照射の制御により、前方車両遮光領域SZSの光量(例えば、0ルーメン秒〔lm・s〕または0ルーメン秒〔lm・s〕に近い値)に比して大きい。 The front vehicle left light amount IZS(H), which is the light amount of the front vehicle left light attenuation area GZS(H), and the front vehicle right light amount IZS(M), which is the light amount of the front vehicle right light attenuation area GZS(M), are controlled by the control unit SE. Due to the control of the irradiation of the headlight ZT, the amount of light is large compared to the light intensity of the front vehicle light shielding area SZS (for example, 0 lumen seconds [lm·s] or a value close to 0 lumens seconds [lm·s]).
第2の決定部KE2は、対向車両TSについて、上記したと同様に、図2に示されるように、第1の決定部KE1により決定された対向車両遮光領域STSに近接する対向車両左減光領域GTS(H)及び対向車両右減光領域GTS(M)を決定する。 Regarding the oncoming vehicle TS, the second determining unit KE2 determines, in the same way as described above, as shown in FIG. The area GTS(H) and the oncoming vehicle right light attenuation area GTS(M) are determined.
対向車両左減光領域GTS(H)の光量である対向車両左光量ITS(H)及び対向車両右減光領域GTS(M)の光量である対向車両右光量ITS(M)は、制御部SEによる前照灯ZTの照射の制御により、対向車両遮光領域STSの光量(例えば、0ルーメン秒〔lm・s〕または0ルーメン秒〔lm・s〕に近い値)に比して大きい。 The oncoming vehicle left light intensity ITS (H), which is the light intensity of the oncoming vehicle left light attenuation area GTS (H), and the oncoming vehicle right light intensity ITS (M), which is the light intensity of the oncoming vehicle right light attenuation area GTS (M), are controlled by the control unit SE. Due to the control of the irradiation of the headlight ZT, the light intensity is large compared to the light intensity of the oncoming vehicle light-blocking area STS (for example, 0 lumen seconds [lm·s] or a value close to 0 lumens seconds [lm·s]).
推定部SUは、他車両ZS、TSにおける運転者USの位置を、例えば、他車両ZS、TSの車種を分析することにより推定する。車種の分析は、自車両で集めた情報、例えばカメラ画像に基づいて車種を推定すればよい。あるいは車種の分析は、自車両JSと他車両ZS、TSとの間で通信を用いて車両情報を受領してもよい。なおこの通信は、車車間通信、路車間通信あるいはクラウドを介在するなど任意の通信を採用可能である。
あるいは運転者の位置は、車種の分析を行うことなく簡易的には左側走行の国、地域では右ハンドルと推定するとともに右側走行の国、地域では左ハンドルと推定してもよい。The estimation unit SU estimates the position of the driver US in the other vehicles ZS and TS, for example, by analyzing the vehicle types of the other vehicles ZS and TS. In analyzing the vehicle type, the vehicle type may be estimated based on information collected by the own vehicle, such as camera images. Alternatively, the vehicle type analysis may be performed by receiving vehicle information using communication between the own vehicle JS and other vehicles ZS and TS. Note that this communication can be any type of communication such as vehicle-to-vehicle communication, road-to-vehicle communication, or via a cloud.
Alternatively, the driver's position may be simply estimated to be right-hand drive in countries and regions where the driver drives on the left-hand side, and left-hand drive in countries and regions where the driver drives on the right-hand side, without analyzing the vehicle type.
制御部SEは、前方車両ZSについて、前方車両左減光領域GZS(H)及び前方車両右減光領域GZS(M)のうち、推定部SUにより推定された前方車両ZSの運転者USの位置により近い前方車両右減光領域GZS(M)の前方車両右光量IZS(M)が、推定部SUにより推定された前方車両ZSの運転者USの位置からより遠い前方車両左減光領域GZS(H)の前方車両左光量IZS(H)より小さくなるように、前照灯ZTの照射を制御する。 The control unit SE determines the position of the driver US of the front vehicle ZS estimated by the estimation unit SU among the front vehicle left light attenuation area GZS (H) and the front vehicle right light attenuation area GZS (M) for the front vehicle ZS. The front vehicle right light intensity IZS(M) of the front vehicle right light attenuation area GZS(M) which is closer to the front vehicle right light attenuation area GZS(M) which is farther from the position of the driver US of the front vehicle ZS estimated by the estimation unit SU The irradiation of the headlight ZT is controlled so that it is smaller than the front vehicle left light amount IZS(H) of H).
制御部SEは、対向車両TSについて、上記したと同様に、対向車両左減光領域GTS(H)及び対向車両右減光領域GTS(M)のうち、推定部SUにより推定された対向車両TSの運転者USの位置により近い対向車両右減光領域GTS(M)の対向車両右光量ITS(M)が、推定部SUにより推定された対向車両TSの運転者USの位置からより遠い対向車両左減光領域GTS(H)の対向車両左光量ITS(H)より小さくなるように、前照灯ZTの照射を制御する。 Regarding the oncoming vehicle TS, the control unit SE selects the oncoming vehicle TS estimated by the estimation unit SU from the oncoming vehicle left dimming area GTS(H) and the oncoming vehicle right dimming area GTS(M), as described above. The oncoming vehicle right light amount ITS(M) in the right light attenuation area GTS(M) is closer to the driver US's position than the oncoming vehicle TS estimated by the estimation unit SU. The irradiation of the headlight ZT is controlled so that the left light intensity of the oncoming vehicle in the left dimming area GTS(H) is smaller than the left light intensity ITS(H) of the oncoming vehicle.
〈実施形態1のハードウェア構成〉
図3は、実施形態1の前照灯配光制御装置ZHSのハードウェア構成を示す。<Hardware configuration of embodiment 1>
FIG. 3 shows the hardware configuration of the headlamp light distribution control device ZHS of the first embodiment.
実施形態の前照灯配光制御装置ZHSは、上述した機能を果たすべく、図3に示されるように、プロセッサPCと、メモリMMと、記憶媒体KBと、を含み、必要に応じて、入力部NYと、出力部SYと、更に含む。 The headlamp light distribution control device ZHS of the embodiment includes a processor PC, a memory MM, and a storage medium KB, as shown in FIG. 3, in order to perform the above-mentioned functions. It further includes a section NY and an output section SY.
プロセッサPCは、ソフトウェアに従ってハードウェアを動作させる、よく知られたコンピュータの中核である。メモリMMは、例えば、DRAM(Dynamic Random Access Memory)、SRAM(Static Random Access Memory)から構成される。記憶媒体KBは、例えば、ハードディスクドライブ(HDD:Hard Disk Drive)、ソリッドステートドライブ(SSD:Solid State Drive)、ROM(Read Only Memory)から構成される。記憶媒体KBは、プログラムPRを記憶する。プログラムPRは、プロセッサPCが実行すべき処理の内容を規定する命令群である。 Processor PC is the core of a well-known computer that operates hardware according to software. The memory MM includes, for example, DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory). The storage medium KB includes, for example, a hard disk drive (HDD), a solid state drive (SSD), and a ROM (Read Only Memory). The storage medium KB stores the program PR.

It consists of The output unit SY is composed of, for example, an interface that outputs information to devices such as a liquid crystal monitor, printer, touch panel, or other ECU (Electronic Control Unit) in the host vehicle.
前照灯配光制御装置ZHSにおける機能とハードウェア構成との関係については、ハードウェア上で、プロセッサPCが、記憶媒体KBに記憶されたプログラムPRを、メモリMM上で実行すると共に、必要に応じて、入力部NY及び出力部SYの動作を制御することにより、撮像部SA~制御部SEの各部の機能を実現する。 Regarding the relationship between the functions and hardware configuration of the headlamp light distribution control device ZHS, on the hardware, the processor PC executes the program PR stored in the storage medium KB on the memory MM, and also executes the program as necessary. By controlling the operations of the input section NY and output section SY accordingly, the functions of each section from the imaging section SA to the control section SE are realized.
〈実施形態1の動作〉
図4は、実施形態1の前照灯配光制御装置ZHSの動作を示すフローチャートである。実施形態1の前照灯配光制御装置ZHSの動作について、図4のフローチャートを参照して説明する。<Operation of Embodiment 1>
FIG. 4 is a flowchart showing the operation of the headlamp light distribution control device ZHS of the first embodiment. The operation of the headlamp light distribution control device ZHS of Embodiment 1 will be described with reference to the flowchart of FIG. 4.
以下では、説明及び理解を容易にすべく、前方車両ZSに関する動作及び対向車両TSに関する動作の両者を並行して述べる。実施形態1の前照灯配光制御装置ZHSは、前記した両動作を行うことに代えて、前方車両ZSに関する動作のみを行ってもよく、また、対向車両TSに関する動作のみを行ってもよいし、前方車両ZS及び対向車両TSに関する動作の双方を行ってもよい。 Below, in order to facilitate explanation and understanding, both the operation regarding the forward vehicle ZS and the operation regarding the oncoming vehicle TS will be described in parallel. Instead of performing both of the operations described above, the headlamp light distribution control device ZHS of Embodiment 1 may perform only the operation related to the vehicle in front ZS, or may perform only the operation related to the oncoming vehicle TS. However, operations regarding both the forward vehicle ZS and the oncoming vehicle TS may be performed.
ステップST11:撮像部SA(図1に図示。)は、他車両ZS、TS(図2に図示。)の画像、即ち、前方車両ZS及び対向車両TSの両者を含む画像を撮影する。撮像部SAは、前方車両ZS及び対向車両TSの両者を含む画像を撮影することに代えて、前方車両ZSを主に含む画像、及び、対向車両TSを主に含む画像を別々に撮影してもよい。 Step ST11: The imaging unit SA (shown in FIG. 1) takes images of other vehicles ZS and TS (shown in FIG. 2), that is, an image including both the forward vehicle ZS and the oncoming vehicle TS. Instead of capturing an image that includes both the forward vehicle ZS and the oncoming vehicle TS, the imaging unit SA separately captures an image that mainly includes the forward vehicle ZS and an image that mainly includes the oncoming vehicle TS. Good too.
撮像部SAにより前方車両ZS及び対向車両TSの画像が撮影されると、検出部KE(図1に図示。)は、前方車両ZS及び対向車両TSが撮影された画像に基づき、前方車両ZSの位置及び対向車両TSの位置を検出する。前方車両ZSの位置及び対向車両TSの位置は、例えば、XY座標により表される。ここでX軸は自車両JSの前後方向をいい、Y軸は自車両JSの車幅方向をいう。 When images of the forward vehicle ZS and oncoming vehicle TS are photographed by the imaging section SA, the detection section KE (shown in FIG. 1) detects the forward vehicle ZS based on the photographed images of the forward vehicle ZS and the oncoming vehicle TS. The position and the position of the oncoming vehicle TS are detected. The position of the forward vehicle ZS and the position of the oncoming vehicle TS are represented by, for example, XY coordinates. Here, the X axis refers to the longitudinal direction of the host vehicle JS, and the Y axis refers to the vehicle width direction of the host vehicle JS.
ステップST12:第1の決定部KE1(図1に図示。)は、前方車両ZSについて、検出部KEにより検出された前方車両ZSの位置に基づき、図2に示されるように、遮光すべき領域である遮光領域、即ち、前方車両ZSの進行方向の前方及び後方に位置する前方車両遮光領域SZSを決定する。 Step ST12: The first determining unit KE1 (shown in FIG. 1) determines the area to be shaded based on the position of the preceding vehicle ZS detected by the detecting unit KE, as shown in FIG. , that is, the front vehicle light shielding regions SZS located in front and behind the forward vehicle ZS in the traveling direction are determined.
第1の決定部KE1は、対向車両TSについて、上記したと同様に、検出部KEにより検出された対向車両TSの位置に基づき、図2に示されるように、遮光すべき領域である遮光領域、即ち、対向車両TSの進行方向の前方に位置する対向車両遮光領域STSを決定する。 As for the oncoming vehicle TS, the first determination unit KE1 determines a light-shielding area that is a region to be light-shielded based on the position of the oncoming vehicle TS detected by the detection unit KE, as described above. That is, the oncoming vehicle light shielding area STS located in front of the oncoming vehicle TS in the traveling direction is determined.
ステップST13:第2の決定部KE2(図1に図示。)は、前方車両ZSについて、前方車両遮光領域SZSに基づき、前方車両遮光領域SZSの近接する前方車両左減光領域GZS(H)及び前方車両右減光領域GZS(M)を決定する。前方車両左減光領域GZS(H)の光量である前方車両左光量IZS(H)、及び、前方車両右減光領域GZS(M)の光量である前方車両右光量IZS(M)は、前方車両遮光領域SZSの光量に比して大きくなるべきである。IZS(H)>IZS(M)。これは運転者USが存在する側の光量を他方に比して小さくして運転者USへの眩惑を抑止するものである。前方車両左光量IZS(H)及び前方車両右光量IZS(M)の両者の大きさの調整は、制御部SEが前照灯ZTの照射を制御することに行われる。 Step ST13: The second determination unit KE2 (shown in FIG. 1) determines the front vehicle left light attenuation region GZS(H) and Determine the front vehicle right light attenuation area GZS(M). The front vehicle left light amount IZS(H), which is the light amount of the front vehicle left light attenuation area GZS(H), and the front vehicle right light amount IZS(M), which is the light amount of the front vehicle right light attenuation area GZS(M), are The amount of light should be larger than the amount of light in the vehicle light shielding area SZS. IZS(H)>IZS(M). This is to suppress the dazzling of the driver US by reducing the amount of light on the side where the driver US is present compared to the other side.

〈実施形態6の動作〉
実施形態6の前照灯配光制御装置ZHSの動作は、基本的に、実施形態1の前照灯配光制御装置ZHSの動作(図4に図示。)と同様である。<Operation of Embodiment 6>
The operation of the headlamp light distribution control device ZHS of the sixth embodiment is basically the same as the operation of the headlamp light distribution control device ZHS of the first embodiment (shown in FIG. 4).

In the sixth embodiment, the vehicle types of the forward vehicle ZS and the oncoming vehicle TS are simply analyzed using the direction of travel on the road. In other words, if the vehicle is driving on the left, the other vehicle is assumed to be driving on the right, and if driving on the right, the other vehicle is assumed to be driving on the left.

On the left-hand road DR2, the oncoming vehicle right light intensity ITS(M), which is the light intensity of the oncoming vehicle right dimming area GTS(M) which is closer to the right side of the oncoming vehicle TS in the direction of travel, is on the left side of the oncoming vehicle TS in the direction of travel. The irradiation of the headlight ZT is controlled so that it is smaller than the oncoming vehicle left light intensity ITS(H) which is the light intensity of the oncoming vehicle left light attenuation area GTS(H) which is closer.
〈右側通行の場合〉
上記したと同様に、ステップST11で、他車両ZS、TSが対向車両TSであることが検出されると、上記のフローチャートのステップST15で、制御部SEは、上記とは相違して、図13に示されるように、右側通行の道路DR2における対向車両TSの進行方向の左側により近い対向車両左減光領域GTS(H)の光量である対向車両左光量ITS(H)が、対向車両TSの進行方向の右側により近い対向車両右減光領域GTS(M)の光量である対向車両右光量ITS(M)より小さくなるように、前照灯ZTの照射を制御する。<When driving on the right side>
Similarly to the above, when it is detected in step ST11 that the other vehicle ZS, TS is the oncoming vehicle TS, in step ST15 of the above flowchart, the control unit SE, unlike the above, As shown in , the oncoming vehicle left light intensity ITS(H), which is the light intensity of the oncoming vehicle left light attenuation area GTS(H) which is closer to the left side in the traveling direction of the oncoming vehicle TS on the right-hand traffic road DR2, is smaller than that of the oncoming vehicle TS. The irradiation of the headlight ZT is controlled so that it is smaller than the oncoming vehicle right light intensity ITS(M), which is the light intensity of the oncoming vehicle right light attenuation area GTS(M) closer to the right side in the direction of travel.
〈実施形態6の効果〉
上述したように、実施形態6の前照灯配光制御装置ZHSでは、対向車両TSについて、制御部SEは、図12に示されるように、左側通行の場合、対向車両右光量ITS(M)が対向車両左光量ITS(H)より小さくなるように、前照灯ZTの照射を制御する。制御部SEは、上記とは対照的に、図13に示されるように、右側通行の場合、対向車両左光量ITS(H)が対向車両右光量ITS(M)より小さくなるように、前照灯ZTの照射を制御する。ここで、多くの場合に、道路の通行方向(左側通行、右側通行)に基づき、対向車両TSの運転者USの位置(進行方向の右側、左側)が特定される。<Effects of Embodiment 6>
As described above, in the headlight distribution control device ZHS of the sixth embodiment, for the oncoming vehicle TS, the control unit SE controls the oncoming vehicle right light amount ITS (M) when driving on the left, as shown in FIG. The irradiation of the headlight ZT is controlled so that the left light amount ITS(H) of the oncoming vehicle becomes smaller than the left light amount ITS(H). In contrast to the above, as shown in FIG. 13, in the case of right-hand traffic, the control unit SE controls the headlights so that the left light amount ITS (H) of the oncoming vehicle is smaller than the right light amount ITS (M) of the oncoming vehicle. Controls the irradiation of the lamp ZT. Here, in many cases, the position of the driver US of the oncoming vehicle TS (right side, left side in the direction of travel) is specified based on the traffic direction of the road (left side traffic, right side traffic).
従って、実施形態6の前照灯配光制御装置ZHSでは、実施形態1の推定部SUが自車両で得た情報あるいは通信で得た情報に基づいて対向車両TSの運転者USの位置を推定することに代えて、上記した運転者USを特定する方法を用いることにより、対向車両左光量ITS(H)及び対向車両右光量ITS(M)のいずれを相対的に低減させるべきかの決定を簡易に行うことができる。 Therefore, in the headlight distribution control device ZHS of Embodiment 6, the estimation unit SU of Embodiment 1 estimates the position of the driver US of the oncoming vehicle TS based on the information obtained by the own vehicle or the information obtained through communication. Instead, by using the method of identifying the driver US described above, it is possible to determine which of the oncoming vehicle left light intensity ITS (H) and the oncoming vehicle right light intensity ITS (M) should be relatively reduced. It can be done easily.

ここで自車両JSと対向車両TSとの距離が閾値距離よりも短い、相対速度が閾値相対速度よりも大きい、または相対角度が閾値相対角度よりも大きいときというのは、対向車両TSが遮光領域から逸脱しやすいときである。Embodiment 7.

In this case, the amount of light in the dimming region on the side where the driver of the oncoming vehicle TS is estimated to be present is made smaller than that on the other side.
Here, when the distance between the host vehicle JS and the oncoming vehicle TS is shorter than the threshold distance, the relative speed is larger than the threshold relative speed, or the relative angle is larger than the threshold relative angle, it means that the oncoming vehicle TS is in the light-shielding area.

As shown in FIG. 14, the control unit SE controls the oncoming vehicle right light intensity ITS(M), which is the light intensity of the oncoming vehicle right light attenuation area GTS(M) which is closer to the right side in the traveling direction of the oncoming vehicle TS on the left-hand road DR2. ) is smaller than the oncoming vehicle left light intensity ITS(H), which is the light intensity of the oncoming vehicle left light attenuation area GTS(H), which is closer to the left side in the direction of travel of the oncoming vehicle TS. .
〈右側通行の場合〉
制御部SEは、図15に示されるように、右側通行の道路DR2における対向車両TSの進行方向の左側により近い対向車両左減光領域GTS(H)の光量である対向車両左光量ITS(H)が、対向車両TSの進行方向の右側により近い対向車両右減光領域GTS(M)の光量である対向車両右光量ITS(M)より小さくなるように、前照灯ZTの照射を制御する。<When driving on the right side>
As shown in FIG. 15, the control unit SE controls the oncoming vehicle left light intensity ITS(H), which is the light intensity of the oncoming vehicle left light attenuation area GTS(H), which is closer to the left side in the traveling direction of the oncoming vehicle TS on the right-hand road DR2. ) is smaller than the oncoming vehicle right light intensity ITS(M), which is the light intensity of the oncoming vehicle right light reduction area GTS(M) which is closer to the right side in the direction of movement of the oncoming vehicle TS. .
制御部SEは、上記とは対照的に、(1A)距離K2(JT)が閾値距離KTHより長いとき、(1B)相対速度SV2(JT)が閾値相対速度SVTHより小さいとき、または、(1C)相対角度SK2(JT)が閾値相対角度SKTHより小さいとき、上記した前照灯ZTの照射の制御を行わない。 In contrast to the above, the control unit SE controls (1A) when the distance K2 (JT) is longer than the threshold distance KTH, (1B) when the relative speed SV2 (JT) is smaller than the threshold relative speed SVTH, or (1C). ) When the relative angle SK2 (JT) is smaller than the threshold relative angle SKTH, the above-described control of the irradiation of the headlight ZT is not performed.
〈実施形態7の効果〉
上述したように、実施形態7の前照灯配光制御装置ZHSでは、制御部SEは、他車両ZS、TSが対向車両TSであることが検出されると、図14に示されるように、左側通行の場合、対向車両左光量ITS(H)が対向車両右光量ITS(M)より小さくなるように、前照灯ZTの照射を制御し、図15に示されるように、右側通行の場合、対向車両右光量ITS(M)が対向車両左光量ITS(H)により小さくなるように、前照灯ZTの照射を制御する。<Effects of Embodiment 7>
As described above, in the headlamp light distribution control device ZHS of the seventh embodiment, when it is detected that the other vehicle ZS, TS is the oncoming vehicle TS, the control unit SE, as shown in FIG. In the case of left-hand traffic, the illumination of the headlight ZT is controlled so that the left light intensity ITS (H) of the oncoming vehicle is smaller than the right light intensity ITS (M) of the oncoming vehicle, and as shown in FIG. 15, in the case of right-hand traffic. , the irradiation of the headlight ZT is controlled so that the light amount ITS (M) on the right side of the oncoming vehicle becomes smaller than the light amount ITS (H) on the left side of the oncoming vehicle.
これにより、道路DR2が左側通行であるか右側通行であるかを問わず、対向車両TSの運転者USの位置により近い減光領域である、対向車両右減光領域GTS(M)(左側通行の場合。図14に図示。)、及び対向車両左減光領域GTS(H)(右側通行の場合。図15に図示。)を減光する。その結果、実施形態5の前照灯配光制御装置ZHSと同様に、自車両JSの前照灯ZTの照射に起因して、対向車両TSの運転者USによる視認性が悪化するとのグレア現象の発生を、自車両JS及び対向車両TS間の距離、相対速度、及び相対角度の変化に応じて低減することができる。 As a result, regardless of whether road DR2 is for left-hand traffic or right-hand traffic, the oncoming vehicle right dimming area GTS (M) (left-hand traffic) is a dimming area closer to the position of the driver US of the oncoming vehicle TS. (in the case of driving on the right, shown in FIG. 14), and the left dimming area GTS(H) of the oncoming vehicle (in the case of right-hand traffic, shown in FIG. 15). As a result, similar to the headlight distribution control device ZHS of the fifth embodiment, a glare phenomenon occurs in which the visibility of the oncoming vehicle TS to the driver US is deteriorated due to the irradiation of the headlight ZT of the host vehicle JS. The occurrence of this can be reduced according to changes in the distance, relative speed, and relative angle between the host vehicle JS and the oncoming vehicle TS.
多くの場合に、道路の通行方向(左側通行、右側通行)に基づき、対向車両TSの運転者USの位置(進行方向の右側、左側)が特定される。従って、道路の通行方向(左側通行、右側通行)を考慮することによって、実施形態6の前照灯配光制御装置ZHSと同様に、対向車両左光量ITS(H)及び対向車両右光量ITS(M)のいずれを相対的に低減させるべきかの決定を簡易的に行うことができる。 In many cases, the position of the driver US of the oncoming vehicle TS (right side, left side in the direction of travel) is specified based on the direction of travel on the road (left side traffic, right side traffic). Therefore, by considering the traffic direction of the road (left-hand traffic, right-hand traffic), similarly to the headlight distribution control device ZHS of the sixth embodiment, the oncoming vehicle left light amount ITS (H) and the oncoming vehicle right light amount ITS ( It is possible to easily determine which of M) should be relatively reduced.

The operation of the headlamp light distribution control device ZHS of the eighth embodiment is basically the same as the operation of the headlamp light distribution control device ZHS of the first embodiment (shown in FIG. 4).
実施形態8の前照灯配光制御装置ZHSの動作は、他方で、実施形態1の前照灯配光制御装置ZHSの動作と相違して、前方車両ZSが旋回しているか否かに応じて、前照灯ZTの照射を制御する。 On the other hand, the operation of the headlamp light distribution control device ZHS of the eighth embodiment differs from the operation of the headlamp light distribution control device ZHS of the first embodiment, in that the operation of the headlamp light distribution control device ZHS of the eighth embodiment is different from the operation of the headlight light distribution control device ZHS of the embodiment 1 depending on whether the front vehicle ZS is turning. to control the irradiation of the headlight ZT.
図16は、実施形態8の前照灯配光制御装置ZHSの動作を示す。 FIG. 16 shows the operation of the headlamp light distribution control device ZHS of the eighth embodiment.
実施形態8の前照灯配光制御装置ZHSでは、検出部KE(図1に図示。)は、フローチャート(図4に図示。)のステップST11で、他車両ZS、TSが、前方車両ZSであるか否か、及び、旋回しているか否かを検出する。
In the headlamp light distribution control device ZHS of
図16に示されるように、他車両ZS、TSが前方車両ZSであり、かつ旋回していることが検出されると、制御部SE(図1に図示。)は、上記のフローチャートのステップST15で、前方車両ZSの旋回方向の内側、換言すれば、前方車両ZSが旋回するときに描く仮想的な円弧の中心(図示せず。)により近い前方車両右減光領域GZS(M)の光量である前方車両右光量IZS(M)が、前方車両ZSの旋回方向の外側、換言すれば、前方車両ZSが旋回するときに描く仮想的な円弧の中心からより遠い前方車両左減光領域GZS(H)の光量である前方車両左光量IZS(H)より小さくなるように、前照灯ZTの照射を制御する。 As shown in FIG. 16, when it is detected that the other vehicles ZS and TS are the preceding vehicle ZS and are turning, the control unit SE (shown in FIG. 1) executes step ST15 of the above flowchart. In other words, the light intensity of the front vehicle right dimming area GZS(M) which is closer to the center (not shown) of the virtual arc drawn when the front vehicle ZS turns, is inside the turning direction of the front vehicle ZS. The front vehicle right light amount IZS(M) is located outside the front vehicle ZS's turning direction, in other words, the front vehicle left light attenuation area GZS is farther from the center of the virtual arc drawn when the front vehicle ZS turns. The irradiation of the headlight ZT is controlled so that the light amount IZS(H) to the left of the vehicle ahead is smaller than the light amount IZS(H).
