Vehicle interior temperature value (ID) and vehicle humidity value (IH) are mobile terminal collections, and the outer temperature value (PD) of the car is automobile collection,
Then before the critical data information of automobile is obtained, the communication connection set up between mobile terminal and automobile, the communication link are also needed
The mode of connecing can include USB (Universal Serial Bus, USB) communication, wireless blue tooth communication or wireless
Fidelity (Wireless-Fidelity, WIFI) communication etc..
If being gathered jointly specifically, the critical data information is mobile terminal and automobile, when automobile and mobile terminal
Set up after communication connection, user can be by opening the related application in mobile terminal come the automatic key for obtaining automobile
Data message.It should be noted that the critical data information can in advance be gathered by mobile terminal and automobile and is stored in each
Data storage storehouse in, when user open related application when, mobile terminal can be obtained from the data storage storehouse and preserved
Newest critical data information.Certainly, the critical data information can also be mobile terminal to automobile user's opening is related should
With the instant data for just starting collection after program.
S102, according to the critical data information judge whether the automobile can be atomized, if the automobile can be atomized,
Following step S103 is performed, if the automobile will not be atomized, following step S104 is performed.
In the present embodiment, Treatment Analysis can be carried out to the critical data information by algorithm, whether to judge the automobile
It can be atomized.It is preferred that, above-mentioned steps S102 can specifically include：
(1) calculating analysis is carried out to the vehicle interior temperature value (ID) and vehicle humidity value (IH), obtains dew point temperature value (LD).
(2) judge whether the automobile can be atomized according to the dew point temperature value (LD) and the outer temperature value (PD) of car.
In the present embodiment, the dew point temperature value (LD) refers to that air is cooled down in the case where moisture content and air pressure are constant
To temperature during saturation, image point says to be exactly temperature when vapor is changed into dewdrop.When the moisture in air reaches saturation shape
So-called mist is formd after state on glass, that is, is atomized.Specifically the dew point temperature value can be obtained by following calculation formula
(LD)：
LogEW=0.66077+7.5ID/ (237.3+ID)+[log10 (IH) -2]；

Including：
The difference information (JD) and pre-set threshold value (M) are compared；
If the difference information (JD) is not less than the pre-set threshold value (M) (i.e. PD-LD=JD >=M), judge that the automobile can be sent out
Fog；
If the difference information (JD) is less than the pre-set threshold value (M) (i.e. PD-LD=JD ＜ M), judge that the automobile will not be sent out
Fog.
In the present embodiment, the pre-set threshold value (M) is generally set by system default, is for example that producer has been when mobile terminal dispatches from the factory
It is configured to have got well.Learnt through many experiments, M is generally 1 DEG C, even PD-LD=JD >=1, then shows the front windshield of the automobile
Glass is likely to be atomized, if PD-LD=JD ＜ 1, shows the front windshield of the automobile and will not be atomized.
S103, send corresponding defogging operation to the automobile and instruct, so that the automobile is instructed to car according to the defogging operation
Air-conditioning is carried to be adjusted.
In the present embodiment, if JD >=M, show that the front windshield of the automobile is likely to be atomized, it is now, mobile
Terminal can send corresponding defogging operation to automobile and instruct, and to control on-board air conditioner to carry out associated adjustment operation, for example increase car
Dehumidification function of wind speed, the temperature of reduction on-board air conditioner or unlatching on-board air conditioner of air-conditioning etc. is carried, so as to change the in-car
Temperature value (ID) and vehicle humidity value (IH), make JD ＜ M, reach the purpose of demisting.
It is to reach demisting purpose as early as possible in the present embodiment, mobile terminal can be according to different difference informations (JD) to vapour
The step of car sends different defogging operations instructions, i.e., above-mentioned " sending corresponding defogging operation to the automobile to instruct " specifically can be with
