Abstract

The utility model provides a kind of automobile automatic brightness-changing system, including automobile lamp control ECU, light relay, dimmer, long-distance light, dim head lights and meeting detection sensor, meeting detection sensor connects automobile lamp and controls ECU, and automobile lamp controls ECU output signal trigger relay coil.The utility model checks that sensor detects come vehicle by meeting, check that sensor sends instructions to automobile lamp and controls ECU by meeting, the automobile lamp control ECU relay coil that sets out makes relay switch work, and controls automatic lighting switch control by relay switch and closes long-distance light.

Description

A kind of automobile automatic brightness-changing system

Technical field

The utility model relates to automobile lighting systems, and in particular to a kind of automobile automatic brightness-changing system.

Background technique

Automobile during driving at night, get on the bus and fewer by especially country road, and must Kaiyuan City's light can just see In the case where clear road, if meeting closes high beam not in time often will cause traffic accident.

Utility model content

Problem to be solved in the utility model is to provide a kind of automobile for the above-mentioned deficiency in the presence of the prior art Automatic brightness-changing system can automatically switch dipped beam and high beam.

To achieve the above object, the utility model uses the following technical solution: controlling ECU, lamp including automobile lamp Optical relay, dimmer, long-distance light, dim head lights and meeting detection sensor, the light relay include relay Device coil and relay switch, the relay switch are sequentially connected dimmer and long-distance light, the relay switch according to Secondary to connect the dimmer and dim head lights, the meeting detection sensor connects the automobile lamp and controls ECU, the vapour Vehicle car light controls ECU output signal and triggers the relay coil.

Further, a kind of automobile automatic brightness-changing system further includes automobile data recorder, and the automobile data recorder has place Device is managed, the processor connects the meeting detection sensor.

Further, the meeting detection sensor is the photosensitive sensor that can check meeting.

Further, the meeting detection sensor includes first sensor and second sensor, the first sensor and Second sensor is speed detection sensor, first sensor detection ground and this vehicle relative moving speed, and described the Two sensors detect this vehicle and opposite vehicle relative moving speed.

Compared with the prior art, the utility model has the following beneficial effects: the utility model passes through the light relay The relay switch of device is opened to reconnect dimmer control long-distance light or dim head lights, when night driving road-condition ratio When more complex, the meeting checks that sensor detects and carrys out vehicle, checks that sensor sends instructions to the vapour by the meeting Vehicle car light controls ECU, and the automobile lamp control ECU relay coil that sets out makes the relay switch work, and passes through relay The long-distance light is closed in automatic lighting switch control described in device switch control.

The further advantage, target and feature of the utility model will be partially reflected by the following instructions, and part will also pass through Research and practice to the utility model and be understood by the person skilled in the art.

Detailed description of the invention

Fig. 1 is a kind of automobile automatic brightness-changing system connection schematic diagram of the utility model.

Specific embodiment

In order to make technological means of the utility model, creation characteristic, reach purpose and effect is more clear and is easy to Understand, the utility model be further elaborated with reference to the accompanying drawings and detailed description:

Embodiment 1, the utility model proposes include that automobile lamp controls ECU1, light relay 2, dimmer 3, preceding photograph Lamp distance light 4 and dim head lights 5, the light relay 2 include relay coil 7 and relay switch 8, the relay line The 7 cooperation relay switch 8 of circle, the relay switch 8, dimmer 3 and long-distance light 4 are sequentially connected, the relay 8 dimmer 3 of device switch and dim head lights 5 are sequentially connected, and meeting detection sensor 6 is connected to the processor of automobile data recorder 9 On 10, the detection sensor 6 connects automobile lamp control ECU1, sends out when the detection sensor 6 examines vehicle to meeting Signal controls ECU1 to automobile lamp out, and the output signal of the automobile lamp control ECU1 is triggered to the relay coil 7, The relay coil 7 makes the relay switch 8 open the long-distance light 4 or the preceding photograph by the dimmer 3 Lamp dipped beam 5, the dim head lights 5 is opened when wherein meeting starts, and the long-distance light 4 is opened at the end of meeting, described Meeting detection sensor 6 uses photosensitive sensor.

Embodiment 2, the meeting detection sensor 6 include first sensor 11 and second sensor 12, the place It manages device 10 and connects comparison circuit 13, the comparison circuit 13 is converted into electric signal, the comparison circuit by the processor 10 The 13 connection automobile lamps control ECU1；The first sensor 11 and second sensor 12 are speed detection sensor, The first sensor 11 detects ground and this vehicle relative moving speed, and the second sensor 12 detects this vehicle and opposite vehicle phase To movement speed；Electric signal is converted a signal by comparing circuit 13 and sends instructions to processor 10, and the processor 10 will Signal is sent to the automobile lamp control ECU1, controls ECU1 by automobile lamp and switches the dim head lights 5, described The dim head lights 5 can be switched closing after receiving 13 signal of comparison circuit by automobile lamp control ECU1.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the scope of the claims of the utility model.
