Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
The invention provides a kind of automobile air-conditioner control method, as shown in figure 1, including：
Step S1：After starting automatic air-conditioning system, car external environment temperature is detected；
Step S2：Judge the car external environment temperature and low-temperature values set in advance or the relation of high temperature values；It can specifically sentence
Disconnected following condition：Car external environment temperature is less than or equal to default low-temperature values, or car external environment temperature is more than or equal to default height
Temperature value；If meeting one of above-mentioned two condition, step S3 is performed：Air blower pause operating is controlled, and triggers the first timing.If
Above-mentioned two condition is all unsatisfactory for, then performs step S5.
Specifically, the present embodiment be at starting of air conditioner initial stage, by car outside environment temperature, it is determined that at present residing for vehicle
Outside air temperature condition whether be supercooling or overheat, and the car external environment temperature according to actual monitoring and high/low temperature set in advance
Upper lower limit value is contrasted, so as to decide whether that initial pause is performed to the air blower of air-conditioning system, for example, foregoing low-temperature values and
High temperature values can be set to 0 DEG C or 30 DEG C, if the car external environment temperature now detected less than 0 DEG C or higher than 30 DEG C, can be with
Think that vehicle is in a kind of more extreme environment of temperature, then well imagine, start the initial stage of automatic air condition, air blast
Machine will necessarily blow out that wind speed is high, air quantity is big, but wind-warm syndrome is not that supercooling is exactly the air-conditioner wind overheated, in this case, in this reality
Apply and control air blower to perform initial pause in example first, its startup of delay is that is to say, so as to avoid automatic air condition initial start stage
To discomfort caused by occupant, certainly, what the present embodiment considered is delay rather than No starting, therefore is gone back when performing initial tentative
The first timing is triggered, the purpose of the timing is the time for giving the unified operation of air-conditioning system and vehicle drivetrain as slow
Punching.
After step s 3, step S4 is performed：After first timing terminates, control air blower recovers operating.It is for example, right
It is less than 0 DEG C of situation in foregoing car external environment temperature, it should be apparent that, air-conditioning is in heating pattern, and for car external environment temperature
Situation of the degree higher than 30 DEG C, air-conditioning will necessarily be in refrigeration mode, then for both different modes, for the first timing
Specific setting can also be set to the different time according to actual conditions, such as because air blower is dried to in-car, it is normal from physics
Know angle, no matter air-conditioning blowout wind be it is cold be heat, have certain cooling-down effect, then it is contemplated that car external environment temperature
The first timing during higher than 30 DEG C can be more shorter than less than 0 DEG C of the first timing, that is, air blast in cooling mode
Machine more leading than air blower under heating pattern can recover to start, for example the first meter when will be above 30 DEG C is set to 15 seconds, less than 0
DEG C the first timing be set to 30 seconds；Certainly, in practical operation, the present invention does not limit the specific setting of the first timing, namely
It is that can be arranged as required to be arranged to identical time span etc. for other times length or by both, no matter which kind of sets,
Its purpose is all in automatic air condition initial start stage, and the wind for air blower blowout provides a more of short duration time delay, is used for
The air-conditioner wind that directly blowout contrast is big is avoided to cause occupant to be difficult in adapt to for the moment.
Step S5：During air blower operates, air-conditioning design temperature, vehicle interior temperature and air outlet temperature are obtained；Step
S6：Calculate the difference of air-conditioning design temperature and vehicle interior temperature, step S7：According to the difference and air outlet temperature, air blast is controlled
Machine pause operating, and trigger the second timing；
The consideration of above-mentioned steps is when air blower is run, and by conventional Boiler pressure control calculation and can also be combined
Air outlet temperature is monitored, and unconventional pause is performed to air blower and is controlled, to be further ensured that the wind energy of air blower blowout meets
Occupant to the demand of comfortableness, thus in practical operation it is contemplated that it is described herein can be " when air blower is run " before
Car external environment temperature is stated between default low-temperature values and high temperature values, air blower is not carried out situation about initially suspending, and that is to say
After step S3, or it can also be the execution that continued after step S4；Step S5 to step S7 is the another of the present embodiment proposition
Individual pause decision procedure, it is therefore an objective to be further ensured that wind-warm syndrome that the air blower of automatic air condition dries in the running and wind speed meet to multiply
Requirement of the member to comfort level, for example, can be when sky according to the different air-conditioning work pattern of above two (heating or refrigeration)
The difference of design temperature and vehicle interior temperature is adjusted to be more than or equal to default threshold value and when air outlet temperature is less than the first temperature value, or
Person, when the difference is less than the threshold value and air outlet temperature is more than second temperature value, control air blower pause operating；Need pair
This is illustrated, and the design temperature of automatic air condition and the relation of the difference of vehicle interior temperature and predetermined threshold value determine air blower
Rotating speed, air output is that is to say, when the difference is more than or equal to default threshold value, such as 3 DEG C under heating pattern, or in refrigeration mould
When the difference is less than 3 DEG C under formula, air output also can be relatively large, then now, there is also cause occupant uncomfortable due to the temperature difference
Possibility, thus the present embodiment also proposes when calculating the difference also to combine actual leaving air temp, determines whether there is
Necessity carries out pause control to air blower, and the specific setting for foregoing first temperature value and second temperature value can be because that need to set
Put, refer to following example：Design temperature is 28 DEG C, and in-car actual temperature is 20 DEG C, then air quantity will necessarily increase, it is assumed that this
When air outlet temperature be but less than 15 DEG C (first temperature values), then control air blower pause operating, avoid producing uncomfortable；Similarly, exist
Design temperature is 22 DEG C, and in-car actual temperature is 29 DEG C, it is assumed that now air outlet temperature is but higher than 30 DEG C (second temperature values), then
Air blower pause operating is controlled, avoids producing discomfort.
After step S7, step S8 is performed：After foregoing second timing terminates, control air blower recovers operating.Here need
To illustrate that, it is well known that the change of vehicle interior temperature needs air blower to blow out air-conditioner wind to carry out heat exchange change, because
And the purpose of pause is to alleviate discomfort, but it should not stop for a long time, therefore, the present embodiment is proposed during foregoing pause also
Carry out the second timing, such as 1 minute, then after 1 minute, no matter temperature what situation, air blower will be made to recover operating with extensive
The normal operation of multiple air-conditioning system, it is believed that on the one hand second timing is to be provided for air-conditioning system and vehicle drive system
The buffer time of one temperature change, on the other hand also occupant can be made progressively to have adapted to vehicle interior temperature, thus even if leaving air temp
Not in the scope of comfort zone, the huge body-sensing of contrast will not be also produced.
Be noted above during air blower operates, air outlet temperature be also possible to it is not up to standard, such as less than the first temperature
Value or higher than second temperature value, the reason for its behind be that cooling water temperature under heating pattern is not up to standard or refrigeration mode under steam
It is not up to standard to send out device temperature, therefore, in another embodiment of the present invention, as shown in Fig. 2 being derived on the basis of step S5
Step S501：Cooling water temperature, or step S502 are also obtained under heating pattern：Evaporator temperature is also obtained in cooling mode
Degree；And step S7 can also develop into step S701：According to foregoing difference and cooling water temperature (or air outlet temperature), or
Person's step 702：According to foregoing difference and evaporator temperature (or air outlet temperature), control air blower pause operating, and trigger
Second timing.It is to be herein pointed out in Fig. 2 embodiments, because both including collection air outlet temperature and coolant water temperature
Degree or evaporator temperature, then judge whether air blower suspends and operate and trigger the condition of the second timing, can also be：When foregoing
Difference is more than or equal to default threshold value and according to air outlet temperature or any one value of cooling water temperature and the relation of limit value, or
Person, when foregoing difference is less than default threshold value and according to air outlet temperature or the pass of any one value of evaporator temperature and limit value
System, certainly, if it is further noted that using cooling water temperature or evaporator temperature, then for air outlet temperature
The limit value of degree, the first temperature value and second temperature value, it is possible to and do not apply to, thus it is contemplated that being had using air outlet temperature
The numerical value of difference, for example with the 3rd temperature value and the 4th temperature value, it refer to following example：When air-conditioning design temperature is higher than car
Interior 3 DEG C of temperature, and detect that air outlet temperature is less than 30 DEG C of (the 3rd temperature less than 15 DEG C (first temperature values) or coolant water temperature
Value) when, control air blower suspends and triggers the second timing；When air-conditioning design temperature is less than 3 DEG C of vehicle interior temperature, and detect air-out
When mouth temperature is less than 25 DEG C (the 4th temperature value) higher than 30 DEG C (second temperature values) or evaporator temperature, the pause of control air blower is simultaneously
Trigger the second timing.
Further consider, for the air blower in pause, it is recovered the condition of operating and be also not limited only to foregoing meter
When terminate, particularly with the situation in the second timing, if detecting following any pause end condition, can control
Air blower processed recovers operating：Foregoing difference be more than or equal to the threshold value on the premise of, air outlet be more than the first temperature value or
Cooling water temperature is more than the 3rd temperature value；On the premise of the difference is less than the threshold value, air outlet is less than second temperature value
Or evaporator temperature is less than the 4th temperature value；This two kinds of conditions are meant that under different working modes above, if
Cause to suspend because each detection temperature is not up to standard after air blower starts, but met air-out in the interval, each associated temperature
The requirement of comfort level, then even if the second timing does not terminate, can also terminate and suspend and recover air blower operating；If in addition, inspection
Defrosting mode open signal is measured, or detects that A/C switches are changed into OFF by ON, then can equally be terminated and be suspended and recover
Air blower operates, and the design of both conditions is then in order at the consideration of hommization, because in practical operation, occupant has to air-conditioning
Different use demands, such as stills need to defrost to glass in interval, or compressor work is not needed during refrigeration
Only need to dry, then the present invention also allows at the end of the second timing not, terminates and suspends and recover air blower operating.
Based on foregoing embodiments and its preferred scheme, present invention also offers a kind of automobile air conditioner control system, such as
