Beneficial effect: with respect to prior art, the automobile-used horn system of blowing a whistle that the utility model adopts, they can be according to the different road conditions of travelling, control the volume of adjusting the outer loudspeaker of car, make horn volume on different running regions, all can meet the urban area noise strength standard > > of < < People's Republic of China (PRC) regulation, thus the loudspeaker noise on can the road improvement of significant effective.
Accompanying drawing explanation
The building-block of logic of a kind of automobile-used horn system of blowing a whistle that Fig. 1 provides for an embodiment of the present utility model.
The specific embodiment
A kind of automobile-used horn system of blowing a whistle that embodiment the utility model being related to below with reference to accompanying drawing provides is elaborated.
As shown in Figure 1, the embodiment that the utility model relates to, provides a kind of automobile-used horn system of blowing a whistle.It comprises the outer loudspeaker of car, the outer loud speaker of car and control module.Wherein control module comprises PWM chip and slide-changing resistor, and the PWM chip of this control module is controlled the volume of the outer loudspeaker of car by slide-changing resistor.
Further, control module is also connected with GPS module, air bag controlled module, adaptive cruise module, engine control module and the Body control module of place vehicle, and Body control module also comprises sound transducer, ambient light sensor, rain sensor etc.; And it can receive the information from these modules, and then instruct the outer loudspeaker of car and the car mode of operation of loud speaker outward.And control module also comprises switch, in order to open or closing control module.When switch closing control module, at this moment the mode of operation of the outer loudspeaker of car and loud speaker is fixed, and for example, speaker sound decibel is fixed as 105dB-118dB.
During use, all sound decibel limit values that control module can be set the outer loud speaker of car, loudspeaker meet the urban area noise strength standard > > of < < People's Republic of China (PRC) regulation.
GPS module can be transmitted travel information to the control module of the horn system of blowing a whistle, and control module can, according to the noise strength standard of different travels, be adjusted the sound decibel of loudspeaker, loud speaker like this.
Whether adaptive cruise module can will have pedestrian before car, and pedestrian and vehicle whether safety distance signal issue loudspeaker control module.If there is pedestrian before car, and outside safety distance, loudspeaker control module is without simulated engine sound (battery-driven car is special-purpose); If not outside safety distance, the sound of loudspeaker control module vehicle motor.The speed of a motor vehicle is higher, and sound is larger.Maximum decibel meets the urban area noise strength standard > > of < < People's Republic of China (PRC) regulation.
And when stationary vehicle (speed of a motor vehicle is less than 5Km/h), and adaptive cruise module determines that pedestrian is before car in 2m time (this situation similar vehicles is waiting traffic lights), and chaufeur is pressed steering wheel loudspeaker button, and loudspeaker control module does not drive horns blared.And instrument is reminded chaufeur: before car, have pedestrian, forbid blast the horn.
Body control module can ambient light signal, (judgement be daytime or evening, pass through ambient light sensor) and rainfall signal (judge whether to rain, pass through rain sensor) and environmental noise (passing through sound transducer) by bus, issue loudspeaker control module.Rainy day or evening, the safety distance that adaptive cruise module is sent needs to lengthen.The outer loudspeaker sound decibel value of car in daytime and evening is stipulated according to the urban area noise strength standard > > of the < < People's Republic of China (PRC).
And when ambient noise value is greater than the urban area noise strength standard > > of the < < People's Republic of China (PRC), loudspeaker decibel is got < < People's Republic of China (PRC) urban area noise strength standard > > maxim, loudspeaker control module is issued instrument by current noise information, instrument shows: current environment is noisy, lacks blast the horn as far as possible.When being less than the urban area noise strength standard > > of the < < People's Republic of China (PRC), loudspeaker divide Becquerel to be slightly larger than ambient noise, minimum decibel is not less than 40dB, and maxim is no more than < < People's Republic of China (PRC) urban area noise strength standard > > limit value.
When steering wheel loudspeaker button is triggered for a long time, loudspeaker control module can not drive dynamic loud-speaker always incessantly, and it has and triggers discontinuously dynamic loud-speaker.
When air bag explosion, air bag controlled module is issued loudspeaker control module signal.Loudspeaker control module is controlled the outer loud speaker of car and is sent calling for help sound.
When entering the stolen warning of vehicle, or vehicle (is greater than 60Km/h, receives the information from engine control module) while running at high speed on highway, and it is 105dB-118dB that loudspeaker control module can be set the outer speaker sound decibel of car.
The automobile-used horn system of blowing a whistle that the utility model adopts, they can be according to the road conditions of travelling, adjust the volume of the outer loudspeaker of car, make horn volume on different running regions, all can meet the urban area noise strength standard > > of < < People's Republic of China (PRC) regulation, thus the loudspeaker noise on can the road improvement of significant effective.
Above-mentioned example is only for illustration of the utility model; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; in the situation that not departing from the utility model scope; can also make a variety of changes and modification; therefore all technical schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
