Further, combination instrument between microphone at a distance from be 500mm.
Further, the combination instrument vocality detection method based on combination instrument vocality detection device is specifically such as
Under:
It controls sound generation software and inputs alarm song to combination instrument, control combination instrument exports the alarm of different level of sound volume
Sound；
Microphone acquires the alarm volume that combination instrument issues, and inputs volume analysis software, determines that combination instrument can be sent out
Max volume and minimal volume out.
Further, the high alarm sound of warning is used for warning operating condition, and suggestive low alarm sound is used for indicative work
Condition；
The warning operating condition includes: the alarm of coolant temperature height, fatigue drive prompting, the low alarm of engine oil pressure, blind area
Monitoring, alarming, deviation alarm, overspeed alarming and clutch temp temperature alarm；
The indicative operating condition include: turn signal prompt, door open alarm, reversing radar prompt, safety belt alarm, key not
Pull out alarm.
The present invention is low to low alarm by the way that alarm to be divided into the high alarm of suggestive low alarm and warning
Level of sound volume, corresponding alarm decibel is relatively small, and to the level of sound volume of high alarm sound pitch, corresponding alarm decibel is higher, low
The indicative alarm of volume and the warning alarm of louder volume, not only meet functional requirement, also improve user's riding experience.
Detailed description of the invention
Fig. 1 is combination instrument vocality structure of the detecting device schematic diagram provided in an embodiment of the present invention；
Fig. 2 is automobile combination meter provided in an embodiment of the present invention alarm volume design method flow chart.
Specific embodiment
A specific embodiment of the invention is made further detailed below against attached drawing by the description to optimum embodiment
Thin explanation.
Alarm by being divided into the high alarm of suggestive low alarm and warning by the present invention, to different alarms
Sound gives different level of sound volume, improves user's riding experience.
Fig. 2 is automobile combination meter provided in an embodiment of the present invention alarm volume design method flow chart, and this method includes
Following steps:
The vocality of S1, under experimental conditions detection combination instrument judges the max volume that combination instrument can issue
And minimal volume；
Based on the detection device of combination instrument vocality shown in Fig. 1 come the vocality of detection combination instrument, i.e. detection vehicle
It carries the capable of emitting max volume of instrument and most descends volume, provide referential data for the alarm volume design of vehicle, the combination instrument
Generating ability detection device includes:
Combination instrument, is fixed on rack machine 1, and the input terminal of combination instrument and the output end of sound generation software connect；
Microphone is fixed on rack machine 2, and the output end of microphone is connect with the input terminal of volume analysis software, is combined
Instrument between microphone at a distance from be 500mm.
Microphone and combination instrument are placed in anechoic chamber.
Combination instrument vocality detection method based on combination instrument vocality detection device specifically includes following step
It is rapid:
It controlling sound generation software and inputs alarm song to combination instrument, control combination instrument issues different grades of alarm volume,
Sound generation software is set to communicating terminal one,
Microphone acquires the alarm volume that combination instrument issues, and inputs volume analysis software, to determine combination instrument energy
The max volume and minimal volume of sending, volume analyze software and are set to communicating terminal one or communicating terminal two.
S2, the division of level of sound volume is carried out based on max volume and minimal volume, and obtains the corresponding practical hair of each grade
Amount of sound；
It is assumed that the minimal volume of combination instrument is 35db, max volume is 85 decibels, is divided into ten level of sound volume,
The corresponding minimum sounding amount of first level of sound volume, the corresponding maximum phonation volume of the tenth level of sound volume, the corresponding sound of different level of sound volume
It is as shown in table 1 to measure size:
1 level of sound volume of table-actual volume mapping table
In embodiments of the present invention, if the actual volume difference between adjacent two level of sound volume exceeds volume preset value, increase
The level of sound volume of division, until the volume difference of adjacent two grade is less than or equal to volume preset value.
S3, classify to prompt operating condition, be divided into the high alarm sound and suggestive low alarm sound of warning；
High alarm sound may be directly related to the alarm of personal safety, be suitable for warning operating condition, warning operating condition includes: cold
But the alarm of liquid temperature height, fatigue drive prompting, the low alarm of engine oil pressure, the alarm of blind area monitoring, alarming, deviation, overspeed alarming
And clutch temp temperature alarm；
Low alarm sound is usually to be used for indicative operating condition, indicative operating condition includes: in order to avoid user omits and the alarm of sending
Alarm is opened in turn signal prompt, door, reversing radar prompts, safety belt is alarmed, key does not pull out alarm.
S4, it is based on the corresponding actual volume of different brackets, gives high alarm sound and the different level of sound volume of low alarm sound.
The given level of sound volume of low alarm sound, should be avoided that alarm volume is excessive, and the given level of sound volume of high alarm should be kept away
Exempt from that sound is too small, therefore the two needs to give different level of sound volume, to meet the needs of under different operating conditions, it is assumed that present combination
There are ten level of sound volume for instrument, give the 6th level of sound volume of low alarm sound, give the tenth level of sound volume of high alarm.
In embodiments of the present invention, after step s4 further include:
S5, it is tested by vehicle, the low alarm sound and high alarm sound of setting level of sound volume is adjusted.
Identical combination instrument is mounted in different vehicles, due to the difference of whole-car parameters, is needed to setting volume
The low alarm sound and high alarm sound of grade are adjusted, and making an uproar value such as the wind of car can be smaller than SUV, so the alarm that car needs
Decibel is opposite can be lower.
The present invention is low to low alarm by the way that alarm to be divided into the high alarm of suggestive low alarm and warning
Level of sound volume, corresponding alarm decibel is relatively small, and to the level of sound volume of high alarm sound pitch, corresponding alarm decibel is higher, low
The indicative alarm of volume and the warning alarm of louder volume, not only meet functional requirement, also improve user's riding experience.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as using method concept and skill of the invention
The improvement for the various unsubstantialities that art scheme carries out, it is within the scope of the present invention.
