本発明は自動車等の車輌に取付けて使用され、
灯具類を外部の条件に従つて点灯又は消灯するこ
とができる作動制御方法を提供しようとするもの
である。[Detailed Description of the Invention] [Industrial Application Field] The present invention is used by being attached to a vehicle such as an automobile,
The object of the present invention is to provide an operation control method that can turn on or off lamps according to external conditions.
この種の灯具類における作動制御手段として

The operation control means for this type of lighting equipment uses an illuminance detection sensor to calculate the traveling distance, the rate of change in illuminance, and the rate of change in illuminance with respect to time, and for example, determines whether to enter a tunnel and turns on the lamps. That's what I do.

でなく、装置的にも複雑なものとなつていた。 However, even when such an external illuminance change rate is calculated, there is a significant difference between the result and the human sense. In other words, even if the location where the vehicle is located has external conditions that require the headlights to be turned on, for example, when passing under an overpass or when the length of a tunnel is short and the road ahead is bright, This is because there is no need to go to the trouble of turning on headlights in tunnels where they are not required under the Road Traffic Act. Even when there is no need to turn on such a headlamp, conventional control means operate mechanically, which not only involves unnecessary operations that differ from human senses, but also makes the device complex. Ta.

Next, the present invention will be described in more detail with reference to illustrated embodiments. Reference numeral 1 indicates a vehicle such as an automobile, and an illuminance detection sensor 2 with wide-angle directivity and an illuminance detection sensor with narrow-angle directivity are installed near the windshield of the vehicle. 3 is attached.

タ４に接続されている。 The wide-angle illuminance detection sensor 2 is composed of a light-receiving element 2a and an amplifier 2b, as shown in FIG.
a, an amplifier 3b, and an optical lens 3c. In particular, the narrow-angle illuminance detection sensor 3 detects the illuminance in a narrow range in front of the vehicle 1, and the wide-angle illuminance detection sensor 2 detects the illuminance around the vehicle 1. The output sides of both detection sensors are connected to the microcomputer 4.

い。 The above control state will be explained based on FIG. 4.
In the figure, S 1 is the output of wide-angle illuminance detection sensor 2,
S 2 is the output of the narrow-angle illuminance detection sensor 3, and T indicates the brightness of the external environment, with the shaded area being the dark area. In a dark area t 1 such as an overpass that the vehicle encounters while driving, the output S 2 of the narrow-angle illuminance detection sensor 3 hardly decreases because the front of the vehicle is bright, and then the wide-angle illuminance detection sensor 2 detects the dark area. Even if t1 is detected and the output S1 decreases, the microcomputer 4 does not control the loads 5 and 6 at all. Furthermore, even in the case of a dark section t2 of a short tunnel where lighting is not required according to the Road Traffic Act, the output S2 of the narrow-angle illuminance detection sensor 3 drops to a slightly low level, and the wide-angle illuminance detection sensor 2 is delayed. is the dark side
t 2 is detected and its output level drops rapidly, but since the output of the narrow-angle illuminance detection sensor 3 described above drops only slightly, the microcomputer 4 also controls the loads 5 and 6 in this case. do not.

る。 When you encounter a long tunnel (50m or more according to the Road Traffic Act) that requires lighting as stipulated by the Road Traffic Act,
As the area in front of the vehicle becomes very dark, the narrow-angle illuminance detection sensor 3 detects the dark area t 3 and its output S 2 drops rapidly, and after a delay, the wide-angle illuminance detection sensor 2 detects the dark area t 3 and outputs Only when S 1 also decreases rapidly and the outputs from both detection sensors decrease, the microcomputer 4 controls the loads 5 and 6 to operate, that is, to turn on the lights. In this case, the microcomputer 4 is activated when the level of output reduction in both detection sensors falls below a preset certain level.

ることも考慮される。 When stopping the operation of the load, that is, when coming out of a long tunnel, the narrow-angle illuminance detection sensor 3 first detects the brightness at the exit of the tunnel, its S 2 gradually rises, and then wide-angle illuminance detection sensor 3 detects the brightness at the exit of the tunnel. The sensor 2 detects the brightness of the exit and its output S 1 suddenly rises, and when both rising levels exceed a certain level, the microcomputer 4 operates to stop the operation of the loads 5 and 6. This is how it is controlled. In addition, lighting lights are installed inside the tunnel, but the brightness of the lighting lights is set to a certain level so that the operation does not stop, and the AC component contained in the light from the lighting lights is detected. It is also possible to distinguish between outside light and a tunnel by using a sensor to detect it. Furthermore, in the case of narrow-angle illuminance detection sensors, consideration should be given to installing them slightly to the left rather than directly in front of the vehicle in order to avoid direct light from oncoming vehicles. .

Just make sure to install it in the appropriate position.

As explained above, the method for controlling the operation of vehicle lights according to the present invention uses a combination of a narrow-angle illuminance detection sensor and a wide-angle illuminance detection sensor, and detects when the output from both detection sensors falls below a certain level. Since it is designed to operate only occasionally, it will not operate if the output of either detection sensor decreases, so there will be no unnecessary operation when passing over an overpass or short tunnel that does not require the lighting of the lamp. , which has the excellent effect of being able to approach human sensations as closely as possible.
更に、指向性の異なる２個の照度検出センサー

実に動作が行えるという優れた効果も奏する。 Furthermore, since only two illuminance detection sensors with different directivities are used, the apparatus has the advantage of being simple and capable of reliable operation.
