S200, according to the actually rate of having a full house in regional judge whether open VMC；Specifically, if occurring one
Or in multiple regions actually have a full house rate exceed it is default have a full house rate when, illustrate now in-car personnel amount it is more, Ke Nengxu
Fresh-air ventilation is wanted, VMC should be opened.Otherwise, when the rate of actually having a full house in regional is less (such as respectively less than default
Have a full house rate) when, then control VMC to be closed.It should be understood that in the present embodiment, the initial shape of VMC
State is closed mode.
After VMC is opened, then step S300 is performed, obtain new according to the rate of actually having a full house in in-car regional
The running status of wind system, and according to the operation of the running status of VMC control air-conditioning system.It is possible to further by newly

In one embodiment, as shown in figure 3, above-mentioned steps S200 further comprises：
Whether S210, the rate of actually having a full house judged respectively in in-car regional are less than or equal to default first with reference to full
Seat rate；Specifically, first can be 40%~50% with reference to the rate of having a full house, and first can be according in current region with reference to the rate of having a full house
The material elementses such as space size are determined.
If in S220, more than one region actually have a full house rate more than default first with reference to have a full house rate when, control
VMC is opened, and fresh air is sent to in-car.Specifically, the VMC, which is opened, includes the unlatching of fresh air air inlet and fresh air exhaust outlet
Open.Further, when the rate of actually having a full house in more than one region is referred to more than default first has a full house rate, control is new
The new blower fan of wind air inlet is started working, and the rate that controls actually to have a full house more than first with reference to rate of having a full house region in fresh air row
Open in air port.For example, when the rate of actually having a full house in front compartment region and/or trunk region is more than 50%, then illustrating may
It is crowded in the presence of in-car, it is sluggish in air circulation, it is necessary to which fresh-air ventilation, now controls VMC to open.
Further, the rate of actually having a full house of current carriage area is more than 50%, and the rate of actually having a full house in trunk region is small
When 50%, then the new blower fan of fresh air air inlet is controlled to start working, and control the fresh air exhaust outlet A in front compartment region to beat
Open, the fresh air exhaust outlet B in trunk region is closed.Current carriage area and the rate of actually having a full house in trunk region
When being all higher than 50%, then the fresh air exhaust outlet B in the fresh air exhaust outlet A and trunk region in front compartment region can be controlled same
When open.Wherein, fresh air exhaust outlet A and fresh air exhaust outlet B keying control can be by controlling the fresh air exhaust valve in it real
It is existing.
If the actually rate of having a full house in regional be respectively less than or equal to default first with reference to have a full house rate when, control fresh air
System is closed.For example, the actually rate of having a full house in front compartment region and trunk region is respectively less than or equal to 50%
When, now illustrate that in-car effective strength is not up to the half of in-car setting amount of seats, interior space is more loose, is conducive to car
Interior air flow, at this point it is possible to VMC is not turned on, to reduce energy consumption.
In one embodiment, above-mentioned steps S300 further comprises：
S310, according to first with reference to rate of having a full house and default one or more second with reference to having a full house rate, by regional
The interior actually rate of having a full house is divided into multiple ratios intervals, wherein, each ratio interval is correspondingly arranged on fresh air air intake and refers to wind
Speed.Specifically, the second quantity for referring to rate of having a full house can be two, and first can with reference to the rates of having a full house with reference to rate of having a full house and two second
So that the actually rate of having a full house being currently needed in fresh-air ventilation region is divided into 4 ratio intervals.For example, two second references are had a full house
Rate can be 75% and 100%.So, above-mentioned 4 ratio intervals be expressed as (0,50%], (50%, 75%], (75%,
100%] and (100% ,+∞].Wherein, ratio it is interval (0,50%] the fresh air air intake that is correspondingly arranged with reference to wind speed can be 0,
I.e. now VMC is closed.Further, the interval corresponding fresh air of each ratio is different with reference to wind speed,
Such as, ratio it is interval (50%, 75%] corresponding fresh air is with reference to the wind speed that wind speed is when new blower fan is in low-grade air-supply, ratio is interval
(75%, 100%] corresponding fresh air with reference to wind speed is that new blower fan is in wind speed when middle-grade is blown, ratio it is interval (100% ,+
∞] corresponding fresh air is with reference to the wind speed that wind speed is when new blower fan is in high-grade air-supply.The actually rate of having a full house i.e. in current region is got over
Greatly, the interval corresponding fresh air of its affiliated ratio is bigger with reference to wind speed.
S311, the rate of actually having a full house judged respectively in in-car regional affiliated ratio interval；For example, front compartment region
Interior rate of actually having a full house is 60%, its affiliated ratio interval for ratio it is interval (50%, 75%].Trunk region is actually had a full house
Rate is 80%, its affiliated ratio interval for ratio it is interval (75%, 100%].
S312, the interval corresponding fresh air air intake of the affiliated ratio of the rate of actually having a full house in regional referred into wind speed respectively
As the corresponding required fresh air intake velocity of regional, wherein, each region one required fresh air intake velocity of correspondence.Tool
Body, if for example, the affiliated ratio interval of the rate of actually having a full house of current region for ratio it is interval (50%, 75%], then will be current
Fresh air intake velocity is set to wind speed during new blower fan low grade air-supply, that is, controls new blower fan with underdrive operating；If current region
The affiliated ratio interval for rate of actually having a full house for ratio it is interval (75%, 100%] when, then current fresh air intake velocity is set to newly
Wind speed when blower fan middle-grade is blown, that is, control new blower fan to be run with middle-grade；If the affiliated ratio of the rate of actually having a full house of current region
Interval for (100% ,+∞] when, then current fresh air intake velocity is set to wind speed when new blower fan top grade is blown, that is, controlled new
Blower fan is run with top grade.For example, the affiliated ratio in front compartment region it is interval (50%, 75%] required intake velocity be new blower fan
Wind speed during in low grade air-supply.The affiliated ratio in trunk region it is interval (75%, 100%] required intake velocity be fresh air
Machine is in wind speed when middle-grade is blown.
S313, according to in-car multiple regions it is corresponding it is multiple needed for fresh air intake velocity obtain it is multiple needed for fresh air enter wind speed
Intake velocity needed for maximum in degree.For example, the corresponding required intake velocity in above-mentioned two region is compared, obtain maximum
Required intake velocity.Specifically, intake velocity needed for the maximum can be in wind speed when middle-grade is blown for fresh air machine.
S314, the current fresh air intake velocity that intake velocity needed for maximum is set to VMC.As shown in figure 1, by
In fresh air air inlet only one of which, therefore to ensure the fresh-air ventilation effect of in-car regional, by the maximum institute of regional
Intake velocity is needed to be set to the current fresh air intake velocity of VMC.
Certainly, in other embodiments, it is multiple that fresh air air inlet, which can also have, i.e., be provided with each region new
Wind air inlet, now, the fresh air air inlet in regional can be controlled individually, can also be jointly controlled.Accordingly, each area
Fresh air intake velocity in domain can be controlled individually, can also be jointly controlled.
In one embodiment, after VMC is opened, it can also be further determined that newly according to the temperature difference outside in-car
The air-supply gear of blower fan, further to adjust fresh air intake velocity.Specifically, it can choose according to the new of rate determination of actually having a full house
Less one is set to current fresh air air intake in wind intake velocity and the fresh air intake velocity determined according to car inside and outside temperature difference
Speed.Further, above-mentioned steps S300 also comprises the following steps：
S315, obtain environment inside car temperature and car external environment temperature, and according to being obtained outside environment inside car temperature and car in
Outer temperature difference；Wherein, environment inside car temperature can be by setting temperature sensor or temperature-sensitive bag in the car etc. to detect acquisition, car
External environment temperature can be obtained by the detection such as temperature sensor or temperature-sensitive bag for being arranged on outside car.Specifically, inside and outside temperature difference
Environment inside car temperature and car external environment temperature difference can be equal to.
S316, the maximum fresh air intake velocity for determining according to inside and outside temperature difference VMC, specifically, can be according to inside and outside
Temperature difference determines the maximum fresh air air intake gear of VMC, to determine the maximum fresh air intake velocity of VMC.Wherein, newly
Wind air intake gear includes high-grade, middle-grade and low grade successively from big to small, and fresh air air intake gear is bigger, and fresh air intake velocity is bigger,
The power of new blower fan is bigger.Specifically, when it is determined that the VMC maximum fresh air air intake gear for it is high-grade when, now fresh air system
The gear of system includes high-grade, middle-grade and low grade successively from big to small, and the maximum fresh air intake velocity of the VMC is new blower fan
With wind speed during top grade operation.When it is determined that the maximum fresh air air intake gear of the VMC is middle-grade, now VMC
Gear includes middle-grade and low grade from big to small, and top grade is in down state, and now the maximum fresh air of the VMC enters wind speed
Spend wind speed when being run for new blower fan with middle-grade.Similarly, when it is determined that the maximum fresh air air intake gear of the VMC is low grade,
Now the gear of VMC only has low grade to be in upstate, and middle-grade and top grade are in down state, now VMC
Maximum fresh air intake velocity for new blower fan with wind speed during underdrive operating.
S317, judge whether current fresh air intake velocity is more than maximum fresh air intake velocity；Judge current root factually border
Whether the current fresh air intake velocity that rate of having a full house is determined exceedes the maximum fresh air intake velocity of VMC.
If current fresh air intake velocity is more than maximum fresh air intake velocity, step S318 is performed, current fresh air is entered
Wind velocity is adjusted to maximum fresh air intake velocity.For example, can determine that current fresh air intake velocity is new according to the actually rate of having a full house
Blower fan is blown with middle-grade, but determines that the maximum fresh air air intake gear of the new blower fan is low grade according to inside and outside temperature difference, high-grade with
Shelves are down state, now, control new blower fan with underdrive operating.
If current fresh air intake velocity is less than or equal to maximum fresh air intake velocity, current fresh air intake velocity is kept not
Become, i.e. return to step S314.For example, determine that current fresh air intake velocity is blown for new blower fan with low grade according to the actually rate of having a full house,
When the maximum fresh air air intake gear that the new blower fan is determined according to inside and outside temperature difference can be high-grade, do not needed because effective strength is less
High wind shelves air-supply, therefore new blower fan can be kept to be blown with low wind shelves, to reduce energy consumption.
Further, the step of maximum fresh air intake velocity that VMC is determined according to inside and outside temperature difference, specifically wraps
Include：Inside and outside temperature difference is divided into multiple temperature ranges according to a multiple reference temperature values, each temperature range correspondence is set
Maximum fresh air air intake gear is equipped with, so as to new by the affiliated interval maximum for obtaining VMC of actual inside and outside temperature difference
Wind air intake gear.Specifically, above-mentioned steps S316 includes：
When inside and outside temperature difference is less than or equal to the first reference temperature, the maximum fresh air air intake gear of VMC is set
For top grade；Specifically, the first reference temperature can be 3 DEG C~5 DEG C.For example, when inside and outside temperature difference is less than or equal to 5 DEG C, this
When illustrate that the temperature of fresh air air intake and indoor air temperature are closer to, refrigeration or heating effect of the fresh air air intake to air-conditioning system
Influence is smaller, the maximum fresh air air intake gear of VMC can be set into top grade, i.e., the new blower fan can be with top grade air-supply.
When inside and outside temperature difference is more than the first reference temperature and is less than the second reference temperature by the maximum fresh air of VMC
Air intake gear is set to middle-grade；Specifically, the second reference temperature can be 10 DEG C or so.For example, when inside and outside temperature difference is more than 5 DEG C
And during less than or equal to 10 DEG C, now, temperature and the environment inside car temperature of fresh air air intake have a certain distance, and fresh air air intake is to sky
The refrigeration or heating effect of adjusting system have a certain impact, and can now be set to the maximum fresh air air intake gear of VMC
Middle-grade, allows new blower fan with middle-grade or low-grade air-supply, and can not be with top grade air-supply, so as to pass through appropriate control fresh air air intake
Speed, to ensure the refrigeration or heating effect of air-conditioning system.
When inside and outside temperature difference is more than the second reference temperature, the maximum fresh air air intake gear of VMC is set to low
Shelves.For example, when inside and outside temperature difference is more than 10 DEG C, now, the difference of the temperature and environment inside car temperature of fresh air air intake is larger, newly
Refrigeration or heating effect influence of the wind air intake on air-conditioning system is larger, now can be by the maximum fresh air air intake gear of VMC
Low grade is set to, makes new blower fan can only be with low grade air-supply, so that by controlling fresh air intake velocity to reduce fresh air intake, to protect
Demonstrate,prove the refrigeration or heating effect of air-conditioning.
It should be understood that the fresh air air intake gear of new blower fan is divided into third gear from high to low in the present embodiment, i.e., high-grade,
Middle-grade and low grade, fresh air air intake gear are higher, and fresh air intake velocity is bigger.In other embodiments, can also be by new blower fan
