Specific embodiment
The present invention is directed to propose a kind of control logic of more flexible in-car air quality, it can be according to the temperature outside car
Degree, humidity and air quality, under the premise of ensuring in-car air quality and preventing car from hazing, as much as possible using following outside
Ring, but also can air quality is preferable outside vehicle or interior cycle duration is switched to outer circulation with crossing long-time gap, with control
Make interior gas concentration lwevel.
Fig. 5 discloses the structural schematic diagram of on-board air conditioner, although in each different manufacturer, it is vehicle-mounted between different vehicles
The specific structure of air-conditioning will be different, but basic structure is all similar.In on-board air conditioner, inner-outer circulation electricity will use
Machine 201 recycles to control in-vehicle air.Inner-outer circulation motor 201 is recycled inside by control internal-external cycle throttle and outer circulation
Between switch over.When air door completely closes, in-vehicle air carries out interior circulation, and when air door fully opens, in-vehicle air carries out outer
Circulation.When air door part is opened, the mixed mode of the inner-outer circulation of corresponding ratio can be carried out according to the ratio of door opening.
Fig. 1 discloses the implementation procedure of the control method of the in-car air quality of an embodiment according to the present invention.With reference to
Shown in Fig. 1, the control method of the in-car air quality is as follows:
101, original state.In the initial state, in-vehicle air is circularly set in interior circulation pattern, i.e., it is air door is complete
It closes.
102, haze judgment step, calculates the interior predicted value to haze.Under interior circulation pattern, since car forms closing
Space is cut off with external air circulation.After a period of time, interior humidity can increase, and the outer temperature difference is larger in the car
When, it is easy generating the phenomenon that hazing on the glass of automobile.In the judgment step that hazes, it can sentence to a possibility that hazing
It is disconnected.In one embodiment, the interior predicted value to haze is calculated according to glass temperature, vehicle interior temperature and vehicle humidity.
Specifically, vehicle interior temperature and vehicle humidity are obtained by interior Temperature Humidity Sensor first, then according to vehicle interior temperature and car
Humidity calculates interior dew-point temperature.Then glass inner side table is obtained by the temperature sensor for being mounted on vehicle glass inner surface again
The temperature in face.Calculate the temperature on glass inner side surface and the difference of dew-point temperature, the predicted value which hazes as car.
If 103, predicted value is greater than the threshold value that hazes, in-vehicle air is circularly set in outer circulation mode, i.e. opening wind
Door.Original state is returned after circulation pattern operation demisting time interval t4 in addition.In one embodiment, the threshold value that hazes is one
Range, works as predicted value, i.e., when difference is lower than the lower limit for the threshold value that hazes, air door is completely closed, in-vehicle air circulation it is completely set up in
Interior circulation pattern.When between the lower limit and the upper limit that predicted value is in the threshold value that hazes, air door part is opened, and in-vehicle air circulation is set
It is placed in inner-outer circulation mixed mode, the ratio and predicted value of interior circulation and outer circulation, i.e. difference are related.It hazes when predicted value is higher than
When the upper limit of threshold value, air door is fully opened, and in-vehicle air circulation is completely set up in outer circulation mode.Fig. 2 is disclosed according to this hair
The deterministic process for the judgment step that hazes in the control program of the in-car air quality of a bright embodiment.Implementation shown in Fig. 2
In example, the range for the threshold value that hazes is set as 2 DEG C~6 DEG C.When the temperature on glass inner side surface and the difference of dew-point temperature are less than 2 DEG C
When, throttle opening 0%, in-vehicle air recycles completely set up in interior circulation pattern.When the temperature and dew point on glass inner side surface
When the difference of temperature is between 2 DEG C~6 DEG C, linear relationship is presented in throttle opening and difference, and throttle opening is 0%~100%
Between linear change, corresponding with difference, in-vehicle air is circularly set in inner-outer circulation mixed mode at this time.When glass inner side table
When the temperature in face and the difference of dew-point temperature are greater than 6 DEG C, throttle opening 100%, in-vehicle air circulation is completely set up to be followed in outside
Ring mode.In Fig. 2, a point indicates the lower limit of threshold value of hazing, and b point indicates to haze the upper limit of threshold value, and in this embodiment, a point is
2 DEG C, b point is 6 DEG C.In other examples, the specific value of a, b can be determined by real steering vectors.
If 104, in-vehicle air circulation is maintained at interior circulation pattern no more than the threshold value that hazes by predicted value, and in progress
Cycle duration timing.If by taking embodiment shown in Fig. 2 as an example, if the difference of the temperature on glass inner side surface and dew-point temperature
Value is then judged as that the risk to haze is very low less than 2 DEG C, maintains the interior mode recycled, and the duration T of inner loop carries out
Timing.
105, the time of interior circulation continuous timing is not up to first time threshold t1, then returns to the judgment step 102 that hazes, then
It is secondary to judge whether there is the risk that hazes.If the predicted value judged again is still not more than the threshold value that hazes, continue step 104, after
It is recycled in continuous maintenance and interior circulation continuous timing is carried out continuously, i.e., the interior duration T recycled persistently adds up.If judging again
Predicted value be greater than and haze threshold value, then carry out step 103, in-vehicle air be circularly set in outer circulation mode, in addition cyclic module
Original state is returned after formula operation demisting time interval t4.When executing step 103, meeting inner loop continues timing clearing, i.e.,
The duration T of interior circulation is reset, and duration T can restart timing in interior circulation next time.
106, the time of interior circulation continuous timing reaches first time threshold t1, carries out air quality judgment step, examines
The outer air quality of vehicle.Air quality outside vehicle is detected by outside air quality sensor, and outside air quality sensor can be examined
Measuring car outer air index, such as the concentration of PM2.5 etc..
If 107, the outer air quality of vehicle meets specified value, for example the concentration of PM2.5 is lower than the value set, then will be interior
Air circulation is set to outer circulation mode, i.e. opening air door, returns after circulation pattern operation time of exchanging gas interval t2 in addition initial
State.While inner loop continues timing clearing, i.e., the interior duration T recycled is reset, and duration T can be followed next time interior
Restart timing when ring.
If the outer air quality of vehicle is unsatisfactory for specified value, for example, PM2.5 excessive concentration or detect others
In-vehicle air is then circularly set and is maintained at interior circulation pattern by pollutant, and interior circulation continuous timing is carried out continuously, i.e., interior circulation
Duration T persistently adds up.
Fig. 3, which is disclosed, reaches first time threshold in the control program of the in-car air quality of an embodiment according to the present invention
The when program process of outer circulation ventilation is carried out after value.After the duration T recycled inside reaches first time threshold t1, vehicle will do it
The judgement of outer air quality, when air quality is up to standard outside vehicle, circulation pattern operation time of exchanging gas interval t2 is other than meeting to carry out
Ventilation.
108, the time of interior circulation continuous timing is not up to second time threshold t3, then returns to the judgment step that hazes, then return
The judgment step 102 that hazes is returned, judges whether there is the risk that hazes again.If the predicted value judged again is still not more than the threshold that hazes
Value, then continue step 104, continues to interior circulation and interior circulation continuous timing is carried out continuously, i.e., the interior duration T recycled
Persistently add up.Because duration T be it is persistently accumulative, duration T at this time is greater than first time threshold t1, therefore
It will do it step 106, after executing step 107, if circulation in still maintaining, can come step 108 again, judge again
Whether interior cycle duration T reaches second time threshold t3.In one embodiment, when second time threshold t3 is greater than first
Between threshold value t1.During recycling herein, if the predicted value judged in the judgment step that hazes is greater than the threshold value that hazes, step is carried out
103, in-vehicle air is circularly set in outer circulation mode, returns to initial shape after circulation pattern operation demisting time interval t4 in addition
State.When executing step 103, meeting inner loop continues timing clearing, i.e., the interior duration T recycled is reset, duration T meeting
Restart timing in interior circulation next time.If all judgement is not present always in the judgment step that hazes during circulation
Haze risk, then the state of interior circulation can be maintained, and the duration T of interior circulation persistently adds up.
109, the time of interior circulation continuous timing reaches second time threshold t3, then is circularly set in-vehicle air and follows in outside
Ring mode, i.e. opening air door return to original state after circulation pattern operation time of exchanging gas interval t2 in addition.Inner loop is held simultaneously
Continue timing to reset, i.e., the interior duration T recycled is reset, and duration T can restart timing in interior circulation next time.The
Two time threshold t3 are associated with interior gas concentration lwevel.When the duration of interior circulation reaching t3, due to lack with
External air circulation can make interior gas concentration lwevel reach higher level, cause the discomfort of occupant.Therefore, when
When the duration of interior circulation reaches second time threshold t3, can force to be switched to outer circulation for a period of time, by with it is external
Air circulation reduces the concentration of interior carbon dioxide.
Fig. 4 is disclosed in the control program of the in-car air quality of an embodiment according to the present invention and is reached the second time threshold
The when program process of outer circulation ventilation is carried out after value.After the duration T recycled inside reaches first time threshold t1, the outer air of vehicle
Quality dissatisfaction, therefore interior circulation is maintained to continue to run, until after the duration T of interior circulation reaches second time threshold t3,
In order to reduce the concentration of interior carbon dioxide, circulation pattern operation time of exchanging gas interval t2 takes a breath other than forcing.Due to
Reaching after second time threshold t3 is to force to be switched to outer circulation to take a breath, and completes to return to original state after ventilation,
Therefore within the time cycle of t3, this method will all complete a complete period.
First time threshold t1, second time threshold t3, demisting time interval t4, time of exchanging gas interval t2 and vehicle above-mentioned
Type is associated.The specific number of first time threshold t1, second time threshold t3, demisting time interval t4, time of exchanging gas interval t2
Value can be determined by real steering vectors.
Since China has a vast territory, in the winter of northern area, external temperature can be very low, in the extremely low situation of external temperature
Under, there are the risks of frosting.Therefore in order to further include following because of the control method to external extreme low temperature, the in-car air quality
The step of:
Outside temperature is obtained, when outside temperature is lower than defrosting threshold value, in-vehicle air is circularly set and is maintained at outer follow
Ring mode.In one embodiment, defrosting threshold value is -15 DEG C.When outside temperature is lower than defrosting threshold value, will force to maintain outer
Circulation pattern, to prevent frosting.Defrosting threshold value is to cope with the situation of extreme temperature, is not common operating condition, and warm outside vehicle
When degree is lower than defrosting threshold value, it will force to use outer circulation, so the step of step can be understood as an independent triggers.
The control method of in-car air quality of the invention can be according to air quality, the interior risk that hazes, supposition outside vehicle
The factor of gas concentration lwevel is calculated, and under the premise of ensuring in-car air quality and not hazing, is utilized as much as possible
Outer circulation, by interior gas concentration lwevel control in proper level, the use for promoting driver and occupant is comfortable
Degree.The control method of in-car air quality of the invention is mainly the update to control logic, does not increase additional hardware,
It will not influence the use habit of user, cost of implementation is low, significant effect.
