Description
Technical field
The utility model belongs to automobile technical field, more particularly to a kind of horn volume control system and vapour for reminding pedestrian
Car.
Background technology
Loudspeaker are the elements of automobile, and in the process of moving, driver is as needed and regulation presses loudspeaker aloud for automobile
, alert pedestrian and vehicle pay attention to, ensure traffic safety.But with the needs of urban development, car horn becomes noise dirt
The source in dye source, it is therefore desirable to the size of sound volume of automobile horn is controlled, in case it is too high speaker sound occur, and it is caused to make an uproar
The acoustic disturbance people, or sound are too low, do not reach prompting vehicle and the warning purpose taken care of pedestrian.
Especially in the region of the no tootings such as hospital, school, because the volume of existing conventional loudspeaker is larger, and learn
School, hospital need relatively quiet environment, therefore have the regulation of no tooting, and these regions are in itself in the numerous position of pedestrian
Put, road conditions are complicated, and automobile can not prompt pedestrian with blowing a whistle, thus easily make traffic road congestion.
Utility model content
The utility model embodiment provides a kind of horn volume control system for reminding pedestrian, it is intended to solves in school, doctor
Institute needs the no tooting region of relative quiet environment, and automobile can not prompt pedestrian with blowing a whistle, thus easily make traffic road and gather around
The problem of stifled.
The utility model is achieved in that a kind of horn volume control system for reminding pedestrian, and the system includes：Make an uproar
Sonic transducer, distance measuring sensor, processor and adjustable sound volume loudspeaker, noise transducer, distance measuring sensor and adjustable sound volume loudspeaker
It is connected respectively with processor, wherein
Noise transducer gathers the noise decibel value of current environment；
Distance measuring sensor is used for the obstacle distance for detecting preceding object object distance headstock；
Processor calculates the decibel value of horn volume according to the noise decibel value and obstacle distance of current environment, sends extremely
Adjustable sound volume loudspeaker；
Adjustable sound volume loudspeaker send prompting according to the decibel value of horn volume.
Further, the processor includes：
Increment value computing unit, the noise decibel value based on current environment, noise decibel is calculated according to obstacle distance
The increment value of value；
Horn volume decibel value computing unit, calculate the noise decibel value and the noise decibel value increment value it
Increment value sum with, the noise decibel value and the noise decibel value is the decibel value of horn volume.
Further, the size of the noise decibel value increment value is directly proportional to the size of obstacle distance.
Further, the calculation formula of the noise decibel value increment value is as follows：
Wherein, BiAway from headstock distance it is X for barrieriWhen loudspeaker decibel value, B0Collected for noise transducer current
The noise decibel value of environment, Δ BmFor the maximum increment value of noise decibel value, XmFor corresponding to the maximum increment value of noise decibel value
Barrier is away from headstock distance.
Further, the distance measuring sensor is radar sensing or infrared sensor.
Further, the processor is vehicle-mounted ECU or single-chip microcomputer.
The utility model additionally provides a kind of automobile, and the horn volume control of above-mentioned prompting pedestrian is included in the automobile
System.
The horn volume in horn volume control system in the utility model is according to obstacle distance and noise decibel value
Calculate, the horn volume decibel value calculated is slightly higher than the noise decibel value in environment, and both environment will not be made
Into pollution, there are the purpose that and can reaches prompting pedestrian, the especially region in no tooting, due to being slightly above noise point in environment
The loudspeaker prompting of shellfish value, will not both bring lofty noise to quiet environment, and and can reaches the purpose of prompting pedestrian, is advantageous to
Traffic to dredging.
