Description

この発明は、車両の情報のうち少なくとも1つの情報に基づいて、左側の追加灯や右側の追加灯を調光点灯したり消灯したりする車両用照明装置(車両用照明システム)に関するものである。特に、この発明は、調光点灯の時間や点灯率を車速により変える車両用照明装置に関するものである。なお、この明細書において、「路面など」とは、路面およびその路面上の人(歩行者など)や物(ガードレールや他の車両や道路標識や建物など)などを言う。   The present invention relates to a vehicle illumination device (vehicle illumination system) for dimming and turning off a left additional light and a right additional light based on at least one of vehicle information. . In particular, the present invention relates to a vehicular illumination device that changes the time and lighting rate of dimming lighting depending on the vehicle speed. In this specification, “road surface or the like” refers to a road surface, a person (such as a pedestrian) or an object (such as a guardrail, another vehicle, a road sign, or a building) on the road surface.

AFS(Adaptive Front lighting System)のように、車両の少なくとも1つの情報に基づいて、追加灯を調光点灯したり消灯したりする車両用照明装置は、従来からある(たとえば、特許文献1)。以下、従来の車両用照明装置について説明する。従来の車両用照明装置は、制御装置により、車両の少なくとも1つの情報に基づいて、左側の追加灯や右側の追加灯を調光点灯すなわち徐々に点灯したり消灯したりするものである。また、従来の車両用照明装置は、調光点灯する際に、最初に所定の点灯率(たとえば、50%)まで点灯してから後に徐々に点灯率を高めて所定時間に100%まで点灯するものである。このように、従来の車両用照明装置は、追加灯を調光点灯したりするので、自車のドライバーや同乗者および周辺の車両のドライバーや同乗者また歩行者などに違和感を与えるようなことがない。また、従来の車両用照明装置は、最初に所定の点灯率まで点灯してから100%まで点灯するので、調光点灯時間を短くして、できる限り迅速に100%点灯することができる。   2. Description of the Related Art Conventionally, there is a vehicular illumination device that performs dimming on and off of an additional lamp based on at least one piece of information of the vehicle, such as AFS (Adaptive Front Lighting System) (for example, Patent Document 1). Hereinafter, a conventional vehicle lighting device will be described. In a conventional vehicular lighting device, a left side additional lamp or a right side additional lamp is dimmed, that is, gradually turned on or off by a control device based on at least one piece of vehicle information. In addition, when the conventional vehicular lighting device is dimmed, it first lights up to a predetermined lighting rate (for example, 50%) and then gradually increases the lighting rate to light up to 100% at a predetermined time. Is. As described above, since the conventional vehicle lighting device lights the additional light in a dimming manner, the driver or passenger of the vehicle and the driver, passenger or pedestrian of the surrounding vehicle may feel uncomfortable. There is no. In addition, since the conventional vehicular lighting device is lit up to a predetermined lighting rate and then lit up to 100%, the dimming lighting time can be shortened and 100% can be lit as quickly as possible.

ところが、従来の車両用照明装置は、最初に所定の点灯率まで点灯してから100%まで点灯するものであるから、車速に関わらずに調光点灯時間や最初の所定の点灯率が一定である。このために、従来の車両用照明装置は、調光点灯時間を長く設定したり最初の所定の点灯率を低く設定したりすると、車速が速い場合には車両の進行方向において十分な光が得られずに視認性に影響があり、一方、調光点灯時間を短く設定したり最初の所定の点灯率を高く設定したりすると、車速が遅い場合には急に点灯した感じがあり違和感や煩わしさを与える虞があるなどの課題がある。   However, since the conventional vehicle lighting device is lit up to a predetermined lighting rate and then lit up to 100%, the dimming lighting time and the initial predetermined lighting rate are constant regardless of the vehicle speed. is there. For this reason, the conventional vehicular lighting device can obtain sufficient light in the traveling direction of the vehicle when the vehicle speed is high when the dimming lighting time is set long or the initial predetermined lighting rate is set low. However, if the dimming lighting time is set short or the initial predetermined lighting rate is set high, it may feel suddenly lit when the vehicle speed is slow, causing discomfort and annoyance. There is a problem that there is a risk of giving it.

前記の図4は、左側の追加灯1L右側の追加灯1Rの調光点灯(増光点灯)時間と車速との相対関係を示す説明図である。図4において、縦軸に調光点灯時間(sec)をとり、横軸に車速(km/h)をとる。前記制御装置6(中央演算処理装置・CPU12)において、前記の図4に示す左側の追加灯1L右側の追加灯1Rの調光点灯時間と車速との相対関係は、以下のとおりである。すなわち、車速が0〜10(km/h)の場合、左側の追加灯1L右側の追加灯1Rの調光点灯時間が1.0(sec)である。また、車速が90(km/h)以上の場合、左側の追加灯1L右側の追加灯1Rの調光点灯時間が0(sec)、すなわち、瞬時点灯である。そして、車速が10〜90(km/h)の場合、図4の実線に示すように、左側の追加灯1L右側の追加灯1Rの調光点灯時間が1.0〜0(sec)とリニアに変化する(直線的に連続的に変わる)。なお、車速が10〜90(km/h)の場合、図4の点線に示すように、左側の追加灯1L右側の追加灯1Rの調光点灯時間が階段的(段階的)に変わるものでもよい。すなわち、車速が10〜30(km/h)の場合左側の追加灯1L右側の追加灯1Rの調光点灯時間が1.0(sec)であり、車速が30〜50(km/h)の場合左側の追加灯1L右側の追加灯1Rの調光点灯時間が0.75(sec)であり、車速が50〜70(km/h)の場合左側の追加灯1L右側の追加灯1Rの調光点灯時間が0.5(sec)であり、車速が70〜90(km/h)の場合左側の追加灯1L右側の追加灯1Rの調光点灯時間が0.25(sec)である。   FIG. 4 is an explanatory diagram showing the relative relationship between the dimming lighting (intensity lighting) time of the additional lamp 1R on the right side of the additional lamp 1L on the left side and the vehicle speed. In FIG. 4, the vertical axis represents the dimming lighting time (sec), and the horizontal axis represents the vehicle speed (km / h). In the control device 6 (central processing unit / CPU 12), the relative relationship between the dimming lighting time of the additional light 1R on the right side of the additional light 1L on the left side shown in FIG. 4 and the vehicle speed is as follows. That is, when the vehicle speed is 0 to 10 (km / h), the dimming lighting time of the additional lamp 1R on the right side of the left additional lamp 1L is 1.0 (sec). When the vehicle speed is 90 (km / h) or higher, the dimming lighting time of the additional lamp 1R on the left side of the additional lamp 1L on the left side is 0 (sec), that is, instantaneous lighting is performed. When the vehicle speed is 10 to 90 (km / h), as shown by the solid line in FIG. 4, the dimming lighting time of the additional lamp 1R on the right side of the additional lamp 1L on the left side is linear with 1.0 to 0 (sec). (Changes linearly and continuously). When the vehicle speed is 10 to 90 (km / h), even if the dimming lighting time of the additional lamp 1R on the right side of the additional lamp 1L on the left side changes stepwise as shown by the dotted line in FIG. Good. That is, when the vehicle speed is 10 to 30 (km / h), the dimming lighting time of the additional lamp 1R on the left side is 1 (sec) and the vehicle speed is 30 to 50 (km / h). In this case, when the dimming lighting time of the additional lamp 1R on the left side is 1 0.75 (sec) and the vehicle speed is 50 to 70 (km / h), the adjustment of the additional lamp 1R on the right side of the additional lamp 1L on the left side When the light lighting time is 0.5 (sec) and the vehicle speed is 70 to 90 (km / h), the dimming lighting time of the additional light 1R on the right side of the additional light 1L on the left side is 0.25 (sec).

前記の図5は、左側の追加灯1L右側の追加灯1Rの調光点灯の状態を示す説明図である。図5において、縦軸に点灯率(%)をとり、横軸に時間tをとる。前記制御装置6(中央演算処理装置・CPU12)において、前記の図5に示す左側の追加灯1L右側の追加灯1Rの調光点灯は、以下のとおりである。すなわち、点灯条件(たとえば、ステアリングハンドルの操舵角が点灯操舵角以上になる場合やウインカスイッチがONになる場合など)となると、左側の追加灯1Lまたは右側の追加灯1Rは、車速に応じて、点灯率0%(T1参照)から点灯率100%(T1、T2、T3参照)まで瞬時に(一気に)点灯したりあるいは徐々に増大して点灯したりする。前記の調光点灯時間は、前記の図4に示すように、車速に応じて変わる。車速が90(km/h)以上の場合、図5の実線に示すように、点灯率0%(T1参照)から点灯率100%(T1参照)まで瞬時に(一気に)点灯する。また、車速が比較的速い場合、図5の実線に示すように、点灯率0%(T1参照)から点灯率100%(T2参照)まで比較的短い時間で徐々に増大して点灯する。さらに、車速が比較的遅い場合、図5の実線に示すように、点灯率0%(T1参照)から点灯率100%(T3参照)まで比較的長い時間で徐々に増大して点灯する。前記の調光点灯調光消灯の調光制御は、たとえば、パルスワイド変調(PWM)方式や電圧制御方式を用いる(特開2001−213227号、特開2003−159986号公報など参照)。なお、左側の追加灯1Lの点灯操舵角と右側の追加灯1Rの点灯操舵角とは、同じであっても異なっていてもよい。また、左側の追加灯1Lの消灯操舵角と右側の追加灯1Rの消灯操舵角とは、同じであっても異なっていてもよい。   FIG. 5 is an explanatory diagram showing a dimming lighting state of the additional lamp 1R on the right side of the left additional lamp 1L. In FIG. 5, the vertical axis represents the lighting rate (%), and the horizontal axis represents time t. In the control device 6 (central processing unit / CPU 12), dimming lighting of the additional lamp 1R on the right side of the additional lamp 1L on the left side shown in FIG. 5 is as follows. That is, when the lighting condition is satisfied (for example, when the steering angle of the steering wheel is greater than or equal to the lighting steering angle, or when the turn signal switch is turned on), the left additional light 1L or the right additional light 1R depends on the vehicle speed. From a lighting rate of 0% (see T1) to a lighting rate of 100% (see T1, T2, and T3), the light is turned on instantaneously (at once) or gradually increased. The dimming lighting time varies depending on the vehicle speed as shown in FIG. When the vehicle speed is 90 (km / h) or more, as shown by the solid line in FIG. 5, the lighting is instantaneous (at once) from the lighting rate 0% (see T1) to the lighting rate 100% (see T1). When the vehicle speed is relatively fast, as shown by the solid line in FIG. 5, the lighting rate gradually increases from a lighting rate of 0% (see T1) to a lighting rate of 100% (see T2) in a relatively short time. Further, when the vehicle speed is relatively slow, as shown by a solid line in FIG. 5, the lighting rate gradually increases from a lighting rate of 0% (see T1) to a lighting rate of 100% (see T3) in a relatively long time. For the dimming control of the dimming lighting / dimming extinction, for example, a pulse wide modulation (PWM) method or a voltage control method is used (see Japanese Patent Laid-Open Nos. 2001-213227, 2003-159986, etc.). Note that the lighting steering angle of the left additional lamp 1L and the lighting steering angle of the right additional lamp 1R may be the same or different. Further, the turn-off steering angle of the left additional light 1L and the turn-off steering angle of the right additional light 1R may be the same or different.

この実施例1にかかる車両用照明装置は、以上のごとき構成からなり、以下、この実施例1にかかる車両用照明装置の作用について説明する。   The vehicle lighting device according to the first embodiment is configured as described above, and the operation of the vehicle lighting device according to the first embodiment will be described below.

まず、イグニションスイッチ9をONにする。すると、制御装置6において、電源が電源回路14から中央演算処理装置・CPU12に投入され、中央演算処理装置・CPU12は、作動する。すなわち、中央演算処理装置・CPU12は、図6に示すフローチャートの工程を順次処理する。以下、中央演算処理装置・CPU12の工程処理の手順(作用)を図6のフローチャートを参照して説明する。   First, the ignition switch 9 is turned on. Then, in the control device 6, power is turned on from the power supply circuit 14 to the central processing unit / CPU 12, and the central processing unit / CPU 12 operates. That is, the central processing unit / CPU 12 sequentially processes the steps of the flowchart shown in FIG. Hereinafter, the procedure (operation) of the process of the central processing unit / CPU 12 will be described with reference to the flowchart of FIG.

中央演算処理装置・CPU12の作用をスタートさせると、操舵角センサ2は、ステアリングハンドルの操舵角および操舵方向を検出して、検出信号(操舵角信号および操舵方向信号)を制御装置6に出力し、ヘッドランプスイッチ3は、ON信号またはOFF信号を制御装置6に出力し、車速センサ5は、車速を検出して車速信号を制御装置6に出力し、方向指示検出部16は、方向指示の操作を検出して方向指示信号を制御装置6に出力する。中央演算処理装置・CPU12は、操舵角センサ2からの検出信号と、ヘッドランプスイッチ3からのON信号またはOFF信号と、車速センサ5からの車速信号と、方向指示検出部16からの方向指示信号と、をインターフェイス回路11を介して入力する(ステアリング操舵角、方向指示検出 S1)。   When the operation of the central processing unit / CPU 12 is started, the steering angle sensor 2 detects the steering angle and steering direction of the steering wheel and outputs detection signals (steering angle signal and steering direction signal) to the control device 6. The headlamp switch 3 outputs an ON signal or an OFF signal to the control device 6, the vehicle speed sensor 5 detects the vehicle speed and outputs a vehicle speed signal to the control device 6, and the direction indication detection unit 16 outputs the direction indication. An operation is detected and a direction indication signal is output to the control device 6. The central processing unit / CPU 12 detects a detection signal from the steering angle sensor 2, an ON signal or an OFF signal from the headlamp switch 3, a vehicle speed signal from the vehicle speed sensor 5, and a direction indication signal from the direction indication detection unit 16. Are input via the interface circuit 11 (steering steering angle, direction indication detection S1).

つぎに、中央演算処理装置・CPU12は、ヘッドランプスイッチ3がONかOFFかを判断する(H/Lオン? S2)。ヘッドランプスイッチ3がOFFの場合、中央演算処理装置・CPU12は、調光消灯信号を左側の追加灯1Lのドライバー回路13L右側の追加灯1Rのドライバー回路13Rに出力して左側の追加灯1L右側の追加灯1Rを消灯状態にし(左右追加ランプ消灯処理 S3)、その後(S1)に戻る。   Next, the central processing unit / CPU 12 determines whether the headlamp switch 3 is ON or OFF (H / L ON? S2). When the headlamp switch 3 is OFF, the central processing unit / CPU 12 outputs a dimming extinction signal to the driver circuit 13R of the additional lamp 1R on the right side of the driver circuit 13L of the left side additional lamp 1L to output the right side of the left additional lamp 1L. The additional lamp 1R is turned off (left and right additional lamp turn-off processing S3), and then the process returns to (S1).

前記の(S2)において、ヘッドランプスイッチ3がONの場合、中央演算処理装置・CPU12は、左側の追加灯1L右側の追加灯1Rが点灯状態か否かを判断する(追加ランプ点灯? S4)。左側の追加灯1L右側の追加灯1Rが点灯状態でない場合、中央演算処理装置・CPU12は、ステアリングハンドルの操舵角が所定の点灯操舵角以上であるか否か、または、ウインカスイッチがONであるか否かを判断する(所定点灯舵角以上?又はターンオン? S5)。ステアリングハンドルの操舵角が所定の点灯操舵角以上でない場合、または、ウインカスイッチがOFFである場合には、(S1)に戻る。   In the above (S2), when the headlamp switch 3 is ON, the central processing unit / CPU 12 determines whether or not the additional lamp 1R on the right side of the additional lamp 1L on the left side is in a lighting state (additional lamp lighting? S4). . When the additional lamp 1R on the right side is not in the lighting state, the central processing unit / CPU 12 determines whether the steering angle of the steering wheel is equal to or greater than a predetermined lighting steering angle, or the turn signal switch is ON. Whether or not it is more than a predetermined lighting rudder angle or turn-on? S5. If the steering angle of the steering wheel is not equal to or greater than the predetermined lighting steering angle, or if the turn signal switch is OFF, the process returns to (S1).

前記の(S5)において、ステアリングハンドルの操舵角が所定の点灯操舵角以上である場合、または、ウインカスイッチがONである場合、中央演算処理装置・CPU12は、図4の特性に基づいて、車速に応じた調光点灯時間を設定する(車速に応じた調光点灯時間を設定 S6)。つぎに、中央演算処理装置・CPU12は、車速に応じた調光点灯時間が設定された調光点灯信号を左側の追加灯1Lのドライバー回路13Lまたは右側の追加灯1Rのドライバー回路13Rに出力して左側の追加灯1Lまたは右側の追加灯1Rを車速に応じた調光点灯時間で調光点灯する(図5のT1、T2、T3を参照。左右追加ランプ調光点灯処理 S7)。その後(S1)に戻る。   In the above (S5), when the steering angle of the steering wheel is equal to or larger than the predetermined lighting steering angle or when the turn signal switch is ON, the central processing unit / CPU 12 determines the vehicle speed based on the characteristics of FIG. The dimming lighting time according to the vehicle speed is set (the dimming lighting time according to the vehicle speed is set S6). Next, the central processing unit / CPU 12 outputs a dimming lighting signal in which the dimming lighting time is set according to the vehicle speed to the driver circuit 13L of the left additional lamp 1L or the driver circuit 13R of the right additional lamp 1R. Then, the left additional lamp 1L or the right additional lamp 1R is dimmed with a dimming lighting time corresponding to the vehicle speed (see T1, T2, T3 in FIG. 5; left and right additional lamp dimming lighting processing S7). Thereafter, the process returns to (S1).

左側の追加灯1Lまたは右側の追加灯1Rが点灯され、前記の(S4)において、左側の追加灯1L右側の追加灯1Rが点灯状態である場合、中央演算処理装置・CPU12は、ステアリングハンドルの操舵角が所定の消灯操舵角以下であるか否か、または、ウインカスイッチがOFFであるか否かを判断する(所定舵角以下?又はターンオフ? S8)。   When the additional light 1L on the left side or the additional light 1R on the right side is lit and the additional light 1R on the right side of the additional light 1L on the left side is in the lit state in (S4), the central processing unit / CPU 12 It is determined whether or not the steering angle is equal to or less than a predetermined turn-off steering angle, or whether or not the turn signal switch is OFF (is equal to or less than the predetermined steering angle? Or turn-off? S8).

前記の(S8)において、ステアリングハンドルの操舵角が所定の消灯操舵角以下である場合、または、ウインカスイッチがOFFである場合、中央演算処理装置・CPU12は、調光消灯信号を左側の追加灯1Lのドライバー回路13Lまたは右側の追加灯1Rのドライバー回路13Rに出力して左側の追加灯1Lまたは右側の追加灯1Rを調光消灯する(左右追加ランプ調光消灯処理 S)。その後(S1)に戻る。前記の(S8)において、ステアリングハンドルの操舵角が所定の消灯操舵角以下でない場合、または、ウインカスイッチがONである場合、中央演算処理装置・CPU12は、(S1)に戻る。 In the above (S8), when the steering angle of the steering wheel is equal to or smaller than the predetermined turn-off steering angle, or when the turn signal switch is OFF, the central processing unit / CPU 12 sends the dimming turn-off signal to the left side additional light. 1L driver circuit 13L or the right-side additional lamp 1R is outputted to the driver circuit 13R turns off additional lamp 1L or the right-side additional lamp 1R dimming the left of (left and right additional lamp light dimming process S 9). Thereafter, the process returns to (S1). If the steering angle of the steering wheel is not equal to or less than the predetermined extinguishing steering angle in (S8), or if the turn signal switch is ON, the central processing unit / CPU 12 returns to (S1).

この実施例1にかかる車両用照明装置は、以上のごとき構成および作用からなり、以下、この実施例1にかかる車両用照明装置の効果について説明する。   The vehicle lighting device according to the first embodiment is configured and operated as described above. Hereinafter, effects of the vehicle lighting device according to the first embodiment will be described.

この実施例1にかかる車両用照明装置は、以上のごとき構成および作用から明らかなように、調光点灯時間を車速が速いほど短く変えることができるので、車速が速い場合には車両7の進行方向において十分な光が得られ、視認性が十分に確保され、交通安全に貢献することができる。一方、この実施例1にかかる車両用照明装置は、調光点灯時間を車速が遅いほど長く変えることができるので、車速が遅い場合には緩やかに点灯して違和感や煩わしさを与える虞がない。すなわち、車速が速い場合、車両7が比較的短時間で曲路(カーブ)や交差点を走行(左折や右折)するので、交通安全上車両7の進行方向の先を速く十分に明るく照明して視認性を確保する必要性がある。一方、車速が遅い場合、車両7が比較的長時間で曲路(カーブ)や交差点を走行(左折や右折)するので、車両7の進行方向の先をある程度の時間である程度の明るさで照明すれば十分に視認性を確保することができ、速く十分に明るく照明する必要性がなく、逆に違和感や煩わしさを与えないようにするほうが好ましい。   As is clear from the configuration and operation as described above, the vehicular lighting device according to the first embodiment can change the dimming lighting time as the vehicle speed increases. Therefore, when the vehicle speed is high, the vehicle 7 proceeds. Sufficient light is obtained in the direction, visibility is sufficiently secured, and it can contribute to traffic safety. On the other hand, the vehicular illumination device according to the first embodiment can change the lighting control lighting time longer as the vehicle speed is slower, so that when the vehicle speed is slow, the lighting device is slowly turned on and there is no possibility of giving a sense of incongruity or annoyance. . In other words, when the vehicle speed is high, the vehicle 7 travels on a curve (curve) or intersection (turns left or right) in a relatively short time. Therefore, the road ahead of the vehicle 7 is illuminated quickly and sufficiently brightly for traffic safety. There is a need to ensure visibility. On the other hand, when the vehicle speed is slow, the vehicle 7 travels on a curve (curve) or intersection (turns left or right) for a relatively long time, so that the vehicle 7 is illuminated with a certain degree of brightness at a certain time in a certain direction. In this case, sufficient visibility can be secured, there is no need to illuminate quickly and sufficiently brightly, and it is preferable not to give a sense of incongruity or annoyance.

また、この実施例1にかかる車両用照明装置は、車速が速い場合(たとえば、90(km/h)以上の場合)には左側の追加灯1Lや右側の追加灯1Rを瞬時に(一気に)点灯するので、車両7の進行方向において十分な光が瞬時にかつ確実に得られ、視認性が十分に確保され、交通安全に貢献することができる。   In addition, in the vehicle lighting device according to the first embodiment, when the vehicle speed is high (for example, when the vehicle speed is 90 (km / h) or higher), the left additional light 1L and the right additional light 1R are instantaneously (at once). Since it lights up, sufficient light can be obtained instantaneously and reliably in the traveling direction of the vehicle 7, sufficient visibility can be ensured, and traffic safety can be contributed.

さらに、この実施例1にかかる車両用照明装置は、左側の追加灯1Lや右側の追加灯1Rの光源がLEDなどの半導体型光源を使用するので、省電力化すなわち消費電力を少なくすることができ、しかも、左側の追加灯1Lや右側の追加灯1Rを小型化することができ、その上、左側の追加灯1Lや右側の追加灯1Rのデザインの多様化や豊富化することができる。   Furthermore, in the vehicular illumination device according to the first embodiment, the light source of the left additional light 1L and the right additional light 1R uses a semiconductor-type light source such as an LED, so that power saving, that is, power consumption can be reduced. In addition, the left additional light 1L and the right additional light 1R can be reduced in size, and the design of the left additional light 1L and the right additional light 1R can be diversified and enriched.

さらにまた、この実施例1にかかる車両用照明装置は、左側の追加灯1Lや右側の追加灯1Rを調光点灯調光消灯するので、自車のドライバーや同乗者および周辺の車両のドライバーや同乗者また歩行者などに違和感を与えるようなことがない。また、この実施例1にかかる車両用照明装置のように、左側の追加灯1Lや右側の追加灯1Rの光源としてLEDなどの半導体型光源を使用することにより、調光点灯制御および調光消灯制御が簡単でかつ確実であるから最適である。光源がLEDなどの半導体型光源の場合におけるパルスワイド変調(PWM)方式の調光点灯制御および調光消灯制御は、たとえば、周波数500Hz、デューディー比間隔0.01%、調光点灯時間約0.2秒〜約0.4秒で100%点灯、および、調光消灯時間約0.5秒〜約1.5秒で0%消灯する。なお、ハロゲンバルブの場合におけるパルスワイド変調(PWM)方式の調光点灯制御および調光消灯制御は、たとえば、周波数100Hz、デューディー比間隔0.1%、調光点灯時間約0.2秒〜約0.4秒で100%点灯、および、調光消灯時間約0.5秒〜約1.5秒で0%消灯する。   Furthermore, the vehicular illumination device according to the first embodiment dimmes and dims the left additional light 1L and the right additional light 1R, so that the driver of the own vehicle, the passenger and the driver of the surrounding vehicle, There will be no discomfort for passengers or pedestrians. In addition, as in the vehicular illumination device according to the first embodiment, dimming control and dimming off are performed by using a semiconductor light source such as an LED as a light source of the left additional lamp 1L and the right additional lamp 1R. It is optimal because control is simple and reliable. In the case where the light source is a semiconductor-type light source such as an LED, the pulse-wide modulation (PWM) dimming control and dimming control are, for example, a frequency of 500 Hz, a duty ratio interval of 0.01%, and a dimming lighting time of about 0. 100% light is turned on in 2 seconds to about 0.4 seconds, and 0% light is turned off in the dimming off time of about 0.5 seconds to about 1.5 seconds. Note that pulse wide modulation (PWM) dimming lighting control and dimming light off control in the case of a halogen bulb are, for example, a frequency of 100 Hz, a duty ratio interval of 0.1%, and a dimming lighting time of about 0.2 seconds to 100% light is turned on in about 0.4 seconds, and 0% light is turned off in the dimming off time of about 0.5 seconds to about 1.5 seconds.

以下、この実施例1の変形例について説明する。すなわち、この実施例1の変形例は、図5の二点鎖線に示すように、最初に所定の点灯率(この例では、50%)まで点灯させてから100%まで調光点灯させるものであって、前記所定の点灯率から100%の点灯率までの点灯時間を車速が速いほど短く変えるものである。すなわち、車速が比較的速い場合、点灯率50%(T1参照)から点灯率100%(T2参照)まで比較的短い時間で徐々に増大して点灯する。一方、車速が比較的遅い場合、点灯率50%(T1参照)から点灯率100%(T3参照)まで比較的長い時間で徐々に増大して点灯する。   Hereinafter, modifications of the first embodiment will be described. That is, in the modification of the first embodiment, as indicated by a two-dot chain line in FIG. 5, the dimming lighting is performed up to 100% after first lighting up to a predetermined lighting rate (50% in this example). Thus, the lighting time from the predetermined lighting rate to the lighting rate of 100% is changed as the vehicle speed increases. That is, when the vehicle speed is relatively fast, the lighting rate gradually increases from a lighting rate of 50% (see T1) to a lighting rate of 100% (see T2) in a relatively short time. On the other hand, when the vehicle speed is relatively slow, the lighting rate gradually increases from a lighting rate of 50% (see T1) to a lighting rate of 100% (see T3) in a relatively long time.

この実施例1の変形例は、以上のごとき構成からなるので、前記の実施例1のものとほぼ同様の作用効果を達成することができる。すなわち、この実施例1の変形例は、所定の点灯率から100%の点灯率までの点灯時間を車速が速いほど短く変えることができるので、車速が速い場合には車両7の進行方向において十分な光が得られ、視認性が十分に確保され、交通安全に貢献することができる。一方、この実施例1の変形例は、所定の点灯率から100%の点灯率までの点灯時間を車速が遅いほど長く変えることができるので、車速が遅い場合には緩やかに点灯して違和感や煩わしさを与える虞がない。   Since the modification of the first embodiment is configured as described above, it is possible to achieve substantially the same operational effects as those of the first embodiment. That is, in the modified example of the first embodiment, the lighting time from the predetermined lighting rate to the lighting rate of 100% can be changed shorter as the vehicle speed is faster. Light is obtained, visibility is sufficiently secured, and it can contribute to traffic safety. On the other hand, in the modified example of the first embodiment, the lighting time from a predetermined lighting rate to a lighting rate of 100% can be changed longer as the vehicle speed is slower. There is no risk of bothering you.

図7〜図9は、この発明にかかる車両用照明装置の実施例2を示す。以下、この実施例2にかかる車両用照明装置について説明する。図中、図1〜図6と同符号は、同一のものを示す。   FIGS. 7-9 shows Example 2 of the illuminating device for vehicles concerning this invention. The vehicle lighting device according to the second embodiment will be described below. In the figure, the same reference numerals as those in FIGS. 1 to 6 denote the same components.

この実施例2にかかる車両用照明装置は、制御装置6により、図7および図8の特性に基づいて、左側の追加灯1Lや右側の追加灯1Rを最初に所定の点灯率まで点灯させてから100%まで調光点灯するものであって、前記最初の所定の点灯率を車速が速いほど高く変えるものである。   In the vehicular illumination apparatus according to the second embodiment, the control device 6 first lights up the left additional lamp 1L and the right additional lamp 1R to a predetermined lighting rate based on the characteristics shown in FIGS. The first predetermined lighting rate is changed higher as the vehicle speed is higher.

前記の図7は、左側の追加灯1L右側の追加灯1Rの調光点灯(増光点灯)の最初の点灯率と車速との相対関係を示す説明図である。図7において、縦軸に最初の点灯率(%)をとり、横軸に車速(km/h)をとる。前記制御装置6(中央演算処理装置・CPU12)において、前記の図7に示す左側の追加灯1L右側の追加灯1Rの最初の点灯率と車速との相対関係は、以下のとおりである。すなわち、車速が0〜10(km/h)の場合、左側の追加灯1L右側の追加灯1Rの最初の点灯率が10(%)である。また、車速が100(km/h)以上の場合、左側の追加灯1L右側の追加灯1Rの最初の点灯率が100(%)、すなわち、瞬時点灯である。そして、車速が10〜100(km/h)の場合、図7の実線に示すように、左側の追加灯1L右側の追加灯1Rの最初の点灯率が10〜100(%)とリニアに変化する(直線的に連続的に変わる)。なお、車速が10〜100(km/h)の場合、図7の点線に示すように、左側の追加灯1L右側の追加灯1Rの最初の点灯率が階段的(段階的)に変わるものでもよい。すなわち、車速が10〜30(km/h)の場合左側の追加灯1L右側の追加灯1Rの最初の点灯率が10(%)であり、車速が30〜50(km/h)の場合左側の追加灯1L右側の追加灯1Rの最初の点灯率が30(%)であり、車速が50〜70(km/h)の場合左側の追加灯1L右側の追加灯1Rの最初の点灯率が50(%)であり、車速が70〜100(km/h)の場合左側の追加灯1L右側の追加灯1Rの最小の点灯率が70(%)である。   FIG. 7 is an explanatory diagram showing a relative relationship between the initial lighting rate of the dimming lighting (intensity lighting) and the vehicle speed of the additional lamp 1R on the right side of the additional lamp 1L on the left side. In FIG. 7, the vertical axis represents the initial lighting rate (%), and the horizontal axis represents the vehicle speed (km / h). In the control device 6 (central processing unit / CPU 12), the relative relationship between the initial lighting rate of the additional light 1R on the right side of the additional light 1L on the left side shown in FIG. 7 and the vehicle speed is as follows. That is, when the vehicle speed is 0 to 10 (km / h), the initial lighting rate of the additional light 1R on the right side of the additional light 1L on the left side is 10 (%). Further, when the vehicle speed is 100 (km / h) or more, the first lighting rate of the additional lamp 1R on the right side of the left additional lamp 1L is 100 (%), that is, instantaneous lighting. When the vehicle speed is 10 to 100 (km / h), the first lighting rate of the additional lamp 1R on the right side of the additional lamp 1L on the left side changes linearly to 10 to 100 (%) as shown by the solid line in FIG. (Changes linearly and continuously). When the vehicle speed is 10 to 100 (km / h), the initial lighting rate of the additional light 1R on the right side of the additional light 1L on the left side changes stepwise as shown by the dotted line in FIG. Good. That is, when the vehicle speed is 10 to 30 (km / h), the first lighting rate of the additional light 1R on the right side of the additional light 1L on the left side is 10 (%), and on the left side when the vehicle speed is 30 to 50 (km / h) When the initial lighting rate of the additional light 1R on the right side of the additional light 1L is 30 (%) and the vehicle speed is 50 to 70 (km / h), the initial lighting rate of the additional light 1R on the right side of the additional light 1L on the left side is When the vehicle speed is 70 to 100 (km / h), the minimum lighting rate of the additional light 1R on the right side of the additional light 1L on the left side is 70 (%).

前記の図8は、左側の追加灯1L右側の追加灯1Rの調光点灯の状態を示す説明図である。図8において、縦軸に点灯率(%)をとり、横軸に時間tをとる。前記制御装置6(中央演算処理装置・CPU12)において、前記の図8に示す左側の追加灯1L右側の追加灯1Rの調光点灯は、以下のとおりである。すなわち、点灯条件(たとえば、ステアリングハンドルの操舵角が点灯操舵角以上になる場合やウインカスイッチがONになる場合など)となると、左側の追加灯1Lまたは右側の追加灯1Rは、車速に応じた最初の点灯率で点灯して(T4参照)、それから点灯率100%(T6参照)まで徐々に増大して点灯する。前記の最初の点灯率は、前記の図8の実線に示すように、車速に応じて変わる。車速が比較的速い場合、たとえば、70〜100(km/h)の場合、最初の点灯率が比較的高く、たとえば、70%であり、点灯率70%(T4参照)から点灯率100%(T6参照)まで徐々に増大して点灯する。また、車速が比較的遅い場合、たとえば、0〜30(km/h)の場合、最初の点灯率が比較的低く、たとえば、10%であり、点灯率10%(T4参照)から点灯率100%(T6参照)まで徐々に増大して点灯する。   FIG. 8 is an explanatory view showing a dimming lighting state of the additional lamp 1R on the right side of the left additional lamp 1L. In FIG. 8, the vertical axis represents the lighting rate (%), and the horizontal axis represents time t. In the control device 6 (central processing unit / CPU 12), dimming lighting of the additional lamp 1R on the right side of the additional lamp 1L on the left side shown in FIG. 8 is as follows. That is, when the lighting condition is satisfied (for example, when the steering angle of the steering wheel is greater than or equal to the lighting steering angle, or when the turn signal switch is turned on), the left additional light 1L or the right additional light 1R corresponds to the vehicle speed. Lights up at the first lighting rate (see T4), and then gradually increases to a lighting rate of 100% (see T6). The initial lighting rate changes according to the vehicle speed as shown by the solid line in FIG. When the vehicle speed is relatively high, for example, 70 to 100 (km / h), the initial lighting rate is relatively high, for example, 70%, and the lighting rate is 70% (see T4) to the lighting rate 100% ( Lights up gradually until T6). Further, when the vehicle speed is relatively slow, for example, 0 to 30 (km / h), the initial lighting rate is relatively low, for example, 10%, and the lighting rate is 10% (see T4) to the lighting rate 100. % (See T6) gradually increases and lights up.

前記の図8の実線においては、高い最初の点灯率から点灯率100%までの調光点灯時間(図8のT4からT6までの時間)と、低い最初の点灯率から点灯率100%までの調光点灯時間(図8のT4からT6までの時間)とは、ほぼ同時間である。ところが、前記の図8の二点鎖線に示すように、高い最初の点灯率から点灯率100%までの調光点灯時間(図8のT4からT5までの時間)を、低い最初の点灯率から点灯率100%までの調光点灯時間(図8のT4からT6までの時間)よりも短くしてもよい。   In the solid line in FIG. 8, the dimming lighting time from the high initial lighting rate to the lighting rate 100% (the time from T4 to T6 in FIG. 8) and the low initial lighting rate to the lighting rate 100%. The dimming lighting time (time from T4 to T6 in FIG. 8) is substantially the same time. However, as indicated by the two-dot chain line in FIG. 8, the dimming lighting time from the high initial lighting rate to the lighting rate of 100% (the time from T4 to T5 in FIG. 8) is reduced from the low initial lighting rate. The dimming lighting time up to 100% lighting time (time from T4 to T6 in FIG. 8) may be shorter.

この実施例2にかかる車両用照明装置は、以上のごとき構成からなり、以下、この実施例2にかかる車両用照明装置の作用について図9のフローチャートを参照して説明する。   The vehicle lighting device according to the second embodiment is configured as described above. Hereinafter, the operation of the vehicle lighting device according to the second embodiment will be described with reference to the flowchart of FIG.

この実施例2にかかる車両用照明装置の作用についての図9のフローチャートは、前記の実施例1にかかる車両用照明装置の作用についての図6のフローチャートの大部分とが同じである。なお、図6と図9中の同符号は、同じ処理工程を示すものである。   The flowchart of FIG. 9 about the effect | action of the vehicle illuminating device concerning Example 2 is the same as most of the flowchart of FIG. 6 about the effect | action of the vehicle illuminating device concerning the said Example 1. FIG. 6 and 9 indicate the same processing steps.

すなわち、工程(S1)から工程(S5)までと、工程(S4)から工程(S8)を経て工程(S9)までとは、同じ処理工程である。そして、前記の(S5)において、ステアリングハンドルの操舵角が所定の点灯操舵角以上である場合、または、ウインカスイッチがONである場合、中央演算処理装置・CPU12は、図7の特性に基づいて、車速に応じた最初の調光点灯率を設定する(車速に応じた最初の調光点灯率を設定 S60)。つぎに、中央演算処理装置・CPU12は、車速に応じた最初の調光点灯率が設定された調光点灯信号を左側の追加灯1Lのドライバー回路13Lまたは右側の追加灯1Rのドライバー回路13Rに出力して左側の追加灯1Lまたは右側の追加灯1Rを車速に応じた最初の調光点灯率で点灯し(図8のT4を参照)、それから点灯率100%まで徐々に増大して点灯する(図8のT5、T6を参照。左右追加ランプ調光点灯処理 S70)。その後(S1)に戻る。   That is, from the step (S1) to the step (S5) and from the step (S4) to the step (S8) to the step (S9) are the same processing steps. When the steering angle of the steering wheel is equal to or greater than the predetermined lighting steering angle or when the winker switch is ON in the above (S5), the central processing unit / CPU 12 is based on the characteristics shown in FIG. The first dimming lighting rate corresponding to the vehicle speed is set (the first dimming lighting rate corresponding to the vehicle speed is set S60). Next, the central processing unit / CPU 12 sends a dimming lighting signal in which the first dimming lighting rate according to the vehicle speed is set to the driver circuit 13L of the left additional lamp 1L or the driver circuit 13R of the right additional lamp 1R. The left side additional light 1L or the right side additional light 1R is lit at the first dimming lighting rate corresponding to the vehicle speed (see T4 in FIG. 8), and then gradually increased to a lighting rate of 100%. (See T5 and T6 in FIG. 8. Left and right additional lamp dimming lighting processing S70). Thereafter, the process returns to (S1).

この実施例2にかかる車両用照明装置は、以上のごとき構成および作用からなるので、前記の実施例1にかかる車両用照明装置の効果とほぼ同様の効果を達成することができる。すなわち、この実施例2にかかる車両用照明装置は、最初の所定の点灯率を車速が速いほど高く変えることができるので、車速が速い場合には車両7の進行方向において十分な光が得られ、視認性が十分に確保され、交通安全に貢献することができる。一方、この実施例2にかかる車両用照明装置は、最初の所定の点灯率を車速が遅いほど低く変えることができるので、車速が遅い場合には緩やかに点灯して違和感や煩わしさを与える虞がない。すなわち、車速が速い場合、車両7が比較的短時間で曲路(カーブ)や交差点を走行(左折や右折)するので、交通安全上車両7の進行方向の先を速く十分に明るく照明して視認性を確保する必要性がある。一方、車速が遅い場合、車両7が比較的長時間で曲路(カーブ)や交差点を走行(左折や右折)するので、車両7の進行方向の先をある程度の時間である程度の明るさで照明すれば十分に視認性を確保することができ、速く十分に明るく照明する必要性がなく、逆に違和感や煩わしさを与えないようにするほうが好ましい。   Since the vehicular lighting device according to the second embodiment is configured and operated as described above, it is possible to achieve substantially the same effect as that of the vehicular lighting device according to the first embodiment. In other words, the vehicular illumination device according to the second embodiment can change the initial predetermined lighting rate higher as the vehicle speed is higher, so that sufficient light can be obtained in the traveling direction of the vehicle 7 when the vehicle speed is high. Visibility is sufficiently secured, which can contribute to traffic safety. On the other hand, since the vehicle lighting device according to the second embodiment can change the initial predetermined lighting rate as the vehicle speed is low, the vehicle lighting device may be slowly turned on when the vehicle speed is low, which may cause discomfort and annoyance. There is no. That is, when the vehicle speed is high, the vehicle 7 travels on a curved road (curve) or intersection (turns left or right) in a relatively short time. There is a need to ensure visibility. On the other hand, when the vehicle speed is slow, the vehicle 7 travels on a curve (curve) or intersection (turns left or right) for a relatively long time, so that the vehicle 7 is illuminated with a certain degree of brightness at a certain time in a certain direction. In this case, it is possible to ensure sufficient visibility, there is no need to illuminate quickly and sufficiently brightly, and it is preferable not to give a sense of incongruity or annoyance.
