Abstract
The present invention provides automatic light changing controller for automobile as a kind of controller for automobile. The automatic light changing controller includes light sensing circuit, signal processing circuit connected to the light sensing circuit, light changing relay connected to the signal processing circuit and the head lamp of automobile, and power supply connected to the said circuits and relay. By means of light sensing technology, the automatic light changing controller realizes the automatic conversion of head lamp in far light and near light to reduce the labor strength of automobile driver, avoid lasting on of the far light lamp to affect night meeting and raise the safety of automobile. The present invention may be made into a small device for containing with available automobile circuit easily.
Description
Technical field
The invention provides the control setup on a kind of automobile, especially a kind of automatic control device of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht.
Background technology
Automobile is at night in opposite directions during meeting, and the both sides that travel relatively should become dipped beam with Der Scheinwerfer mit FernlichtAbblendlichtStandlicht by distance light when certain distance.At present, to the control of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht, continue to use both at home and abroad by the manual original method of navigating mate always.This can make navigating mate feel that operation easier is big, the labour intensity height, and when especially new navigating mate or meeting were frequent, this sensation was more outstanding.In addition, be subjected to the influence of navigating mate self diathesis, the situation of distance light meeting is quite general.This can cause both sides' navigating mate can't see the place ahead road conditions clearly, and easily causes the navigating mate eye fatigue, causes the generation of traffic accident.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of automobile automatic beam change controller, to improve the comfort feature and the running safety of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht control.
The present invention is achieved in that automobile automatic beam change controller, and it has photosensitive circuit, photosensitive circuit links to each other with signal processing circuit, signal processing circuit links to each other with the change light relay, becomes light relay and links to each other with Der Scheinwerfer mit FernlichtAbblendlichtStandlicht, is connected to power supply on photosensitive circuit, signal processing circuit, the change light relay.
Adopt the automobile automatic beam change controller of said structure, the sensitization technology is used for the control of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht, realized the automatic conversion of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht by the distance light dimming, very convenient, the operation easier and the labour intensity of navigating mate have been alleviated, when having eliminated nighttime meeting, because of country beam is opened, the dazzling drawback that does not see road conditions always, therefore can reduce effectively and the traffic accident rate that causes improves the safety that automobile is exercised.This controller working stability is reliable, can be made into small-sized device, with original circuit arrangement of automobile such as power supply, become the easy to connect of light relay, installs simple.
Description of drawings
Fig. 1 is a circuit block diagram of the present invention.
Fig. 2 is the circuit diagram of its a kind of physical circuit.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates structure of the present invention and principle of work.
As shown in drawings, the present invention's automobile automatic beam change controller, it has photosensitive circuit (1), photosensitive circuit links to each other with signal processing circuit (2), signal processing circuit links to each other with change light relay (3), become light relay and link to each other, be connected to power supply (5) on photosensitive circuit, signal processing circuit, the change light relay with Der Scheinwerfer mit FernlichtAbblendlichtStandlicht (4).
On described photosensitive circuit (1), the collecting electrode of photo-transistor BG1 passes through resistance R 1 power connection positive pole, emitter through resistance R 2 ground connection.
On described signal processing circuit (2), the base stage of aerotron BG2 connects the emitter of photo-transistor BG1, collecting electrode meets aerotron BG3 through resistance R 4 base stage, the collecting electrode of aerotron BG3 connects the base stage of aerotron BG4 through resistance R 7, the collecting electrode of aerotron BG4 connects the base stage of aerotron BG5 through resistance R 10, the collecting electrode of aerotron BG5 connects the change light relay, and the grounded emitter of aerotron BG2, BG3, BG4, BG5, collecting electrode are respectively by resistance R 3, R6, R9 power connection positive pole.The base stage of aerotron BG3, BG4, BG5 is also respectively through resistance R 5, R8, R11 ground connection.
The model of aerotron BG1 is 3DU, it is as sensitive piece, be installed in the appropriate location of automotive front, acceptance is sailed infrared ray and the visible light that next automobile sends from the opposite, and these optical signals are converted to electric signal, the signal processing circuit (2) that BG2～BG5 etc. form is carried out processing and amplifying step by step with this electric signal, drive to become the light relay action, thereby automatically the distance light of Der Scheinwerfer mit FernlichtAbblendlichtStandlicht is become dipped beam.
It is original on the automobile becoming light relay, during use, only the collecting electrode of aerotron BG5 need be connected on its input end and get final product.On the former automobile with storage battery be connected in the present invention, as power supply of the present invention (5).When being installed in the present invention on the automobile, only carrying out above-mentioned connection and get final product, very simple.
Regulate the size of resistance R 1 and resistance R 2 resistances, the sensitivity of the quick aerotron BG1 of adjustable lay the grain is so that this light variable controller in the distance (200 meters) of traffic regulation regulation, moves accurately and timely.During action, if Der Scheinwerfer mit FernlichtAbblendlichtStandlicht is distance light then becomes dipped beam automatically that meeting becomes distance light after finishing automatically at this moment; If Der Scheinwerfer mit FernlichtAbblendlichtStandlicht is dipped beam then remain unchanged at this moment, and becomes distance light more automatically after meeting finishes.
The collecting electrode of aerotron BG5 is connected in parallel on the input end that becomes light relay with the control circuit of former Der Scheinwerfer mit FernlichtAbblendlichtStandlicht.When not having the vehicle that travels over there, the present invention does not influence original manual control to Der Scheinwerfer mit FernlichtAbblendlichtStandlicht.
