Description
Technical field
The present invention relates to a kind of automobile safety indication device, is blown a whistle in back car or prepares to overtake other vehicles using side marker light
When, ensure that driver can discover the intention of overtaking other vehicles of rear car in the car, reduce the generation of accident.
Background technology
With the improvement of people's living standards, automobile constantly enters family, the quantity of automobile is being continuously increased, some
The increasingly congestion of the road in city, the automobile on highway is also more and more, because the manufacture level of Hyundai Motor improves constantly,
Also more and more higher, the in-car that often covets can't hear running noise for requirement of the people to the in-car muting function of automobile, and this makes
It is less and less to obtain the in-car vehicle whistle sound that can be heard.When particularly running at high speed, made an uproar due to road and made an uproar very greatly with wind, many vehicles
Window traveling is all closed, is blown a whistle almost meaningless, if at this moment rear car front truck when overtaking other vehicles is not heard and blows a whistle sound or discover rear car
Instruction modulating signal and changing Lane, it is possible to trigger traffic accident, such case is playing music or receipts in Automobile
Situation is particularly pertinent during sound machine.On the other hand, many fresh drivers tend not to notice overtaking other vehicles for rear car due to lacking experience
Indicator lamp is prompted or prompting of blowing a whistle of overtaking other vehicles, and easily triggers road traffic accident, particularly when rear car enters rear view mirror blind zone
It is easier to cause danger.And when being travelled in city, Pedestrians and vehicles staggered case is more complicated, and garage is away from even closer, environment
It is noisy, now if can not both it is noted that the traffic in front, notices that rear car may blow a whistle or be overtaken other vehicles using indicator lamp again
Discover the intention of overtaking other vehicles of rear car, be also likely to that accident occurs.In order to allow motorists to respond the sound of blowing a whistle of overtaking other vehicles of rear car
Or discover overtaking indicating light, ensure itself safety with its car, the present invention proposes a kind of automobile rear car and overtaken other vehicles prompt system.
The content of the invention
The present invention is to solve drive when driver can not timely respond to rear car overtake other vehicles prompting the problem of and propose, use
Automobile rear car proposed by the present invention is overtaken other vehicles prompt system, can guarantee that driver responds sound or the finger of overtaking other vehicles of blowing a whistle of overtaking other vehicles of front vehicle
Show lamp, control the travel speed of vehicle in time and avoid lane change, to ensure that front vehicle can overtake other vehicles safely.
To achieve these goals, present invention employs following technical scheme：
A kind of automobile rear car is overtaken other vehicles prompt system, mainly by：Rear car blow a whistle detecting system, audio frequency processing circuit, rear car turn to refer to
Show that lamp inspection examining system, automobile indicator signal amplification circuit, rear car are overtaken other vehicles identification circuit, speech prompting system of overtaking other vehicles, loudspeaker
Composition.
One or more can be used to blow a whistle sound detection sensor for rear car detecting system of blowing a whistle, installed in the afterbody of automobile, inspection
Rear vehicle whistle sound is surveyed, vehicle whistle sound is a kind of higher source of sound of frequency, and therefore, the present invention carries on the back by filtering out road
Scape noise, obtain vehicle whistle sound.
Audio frequency processing circuit is amplified to the signal for sound detection sensor of blowing a whistle, to reach the intensity of certain signal.
Rear car side marker light detecting system automobile indicator detection sensor has two, is separately mounted to automobile rear
The left and right sides, the indicator lamp of detection rear car flicker, pass through opto-electronic conversion and the electrical signal intensity of filtering acquisition certain amplitude.
Automobile indicator signal amplification circuit has two-way, and the left and right two path signal of acquisition is amplified respectively, with up to
To certain signal intensity.
Rear car identification circuit of overtaking other vehicles enters according to the two paths of signals of audio frequency processing circuit and automobile indicator signal amplification circuit
Row analysis identification, judge the intention of overtaking other vehicles of rear car, while two of the input according to automobile indicator signal detection amplifying circuit
The power of road signal judges that rear car is that preparation left side is overtaken other vehicles or right side is overtaken other vehicles.
Speech prompting system of overtaking other vehicles exports corresponding rear car and overtaken other vehicles voice according to the overtake other vehicles judged result of identification circuit of rear car
Information is simultaneously played back by loudspeaker, prompts driver's front vehicle preparation left side or right side to overtake other vehicles.Overtake other vehicles voice message system
System can also be may be selected to play the information of voice prompt of overtaking other vehicles provided by system by the voice content of the self-defined broadcasting of driver.
The interconnection between each system in the present invention can be completed by wireless modes such as bluetooth communications, to improve
Ease for use.
The present invention has the following advantages that compared with prior art：
1, prior art is directly listened to its car and blown a whistle by driver with the sense of hearing sound or by observing rearview mirror knows that rear car lane change surpasses
Car is intended to, and is had a great influence by road noise and running noise, though noise can be reduced by closing vehicle window, also reduces driver and listens to
Its car is blown a whistle the chance of sound, is unfavorable for safe driving.Part driver because technology it is unqualified or carelessness and not it is observed that after
The instruction modulating signal of car, while due to vision dead zone be present so that some drivers are ignored after overtaking other vehicles in part rearview mirror
Car, the intention of overtaking other vehicles of blown a whistle by detection simultaneously sound and indicator lamp signal identification rear car of the invention, it is ensured that after driver discovers
The prompting of overtaking other vehicles of car, is advantageous to safe driving, more important especially for the fresh driver being lacking in experience.
2, the present invention speech prompting system that can be selected to overtake other vehicles by driver is reported rear car and overtaken other vehicles the content of prompt message, can
The enjoyment driven with increase, is advantageous to safe driving.
3, the present invention is practical, and easy to operate, cost is reasonable, is easy to use and promotes.
Below by drawings and examples, technical scheme is described in further detail.
Brief description of the drawings
Fig. 1 is the circuit theory schematic diagram of the present invention.
