Fig. 2 is according to the theory diagram of the temperature correcting module of the auto Air Conditioner control system of an embodiment of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, describe auto Air Conditioner control system of the present utility model in detail.
Auto Air Conditioner control system of the present utility model can regulate vehicle interior temperature fast, and its control accuracy is high.Below with reference to Fig. 1, auto Air Conditioner control system of the present utility model is described.
Auto Air Conditioner control system of the present utility model mainly comprises human-computer interaction module 10, temperature collect module 20, temperature correcting module 30 and temperature control modules 40.Rider can utilize human-computer interaction module 10 to set car internal object temperature T 0.Temperature control modules 40 is according to parameters such as the default leaving air temp of target temperature value T0, wind speed, after leaving air temp mixes with air in car, temperature collect module 20 utilizes temperature sensor to gather the temperature signal of air in car, obtain observed temperature t, then the Temperature numerical that temperature correcting module 30 collects temperature collect module 20 according to the target temperature value T0 that transmits next observed temperature t by temperature collect module 20 and come by human-computer interaction module 10 transmission is made correction, thereby obtains actual temperature value in car.Simultaneous temperature control module 40 resets the operational factor of air-conditioning system according to car internal object temperature T 0 and the revised temperature value information exported by vehicle interior temperature correcting module 30, such as leaving air temp, blowing pattern, wind speed, compressor state and air inlet pattern etc., and control air-conditioning system and carry out air conditioning according to this corresponding operational factor, so that the vehicle interior temperature after regulating reaches car internal object temperature T 0.So just, formed the closed-loop control of air conditioning for automobiles automatic control system.Should illustrate, temperature control modules 40 needs the vehicle interior temperature value of vehicle interior temperature correcting module 30 outputs, also need the parameter air-conditioner control system simultaneously, temperature as outer in car, leaving air temp, blowing pattern, wind speed, solar radiation, the speed of a motor vehicle, compressor state and air inlet pattern pass to temperature correcting module 30.
In addition, air-conditioner control system can also have other modules, as damper motor control module, wind speed control module and compressor control module; Wherein, damper motor control module, wind speed control module, compressor control module are connected with the output of said temperature control module respectively.
At temperature correcting module 30, carry out in the process of temperature correction, as shown in Figure 2, it is according to the difference of observed temperature t and car internal object temperature T 0 | and Δ u| enables dynamic amending unit 301 or static modification unit 302 with the relation of the dynamic correction temperature gap △ X presetting.Difference when observed temperature t and car internal object temperature T 0 | when Δ u| is greater than dynamic correction temperature gap △ X default in temperature correcting module 30, dynamically amending unit 301 plays a role, its basis | the value of Δ u| is controlled air-conditioning system and is carried out air conditioning, so that the observed temperature t that temperature acquisition mould 20 detects in real time can upgrade according to default speed.When the value of | Δ u| is larger, dynamically amending unit 301 makes vehicle interior temperature upgrade with larger speed; When | when Δ u| reduces gradually, dynamically amending unit 301 slows down the renewal rate of vehicle interior temperature.For describing this dynamic makeover process in detail, now enumerate following example, but any restriction that the utility model is not given an example by this.
For example, when | during Δ u|>10, vehicle interior temperature upgrades with the speed of 10 degree per minute; As | Δ u|>5 and | during Δ u|<=10, vehicle interior temperature upgrades with the speed of 5 degree per minute; As | Δ u|>3 and | during Δ u|<=5, vehicle interior temperature upgrades with the speed of 1 degree per minute.
When | when the value of Δ u| is reduced to a certain scope (for example, below 3 degree), dynamically amending unit 301 quits work, and static modification unit 302 starts to start.Static modification unit 302 is intended to eliminate the static deviation of vehicle interior temperature and car internal object temperature.In the makeover process of static modification unit, can determine static modification value with following formula.That is:
Δy=x0*a+x1*b+x2*c+x3*d+x4*e+x5*f+x6*g
Δ y: the static modification value of vehicle interior temperature;
A: the outer temperature correction of car;
X0: the outer temperature factor of influence of car;
B: leaving air temp correction;
X1: leaving air temp factor of influence;
C: blowing model amendment $$$$ amount;
X2: blowing pattern factor of influence;
D: wind speed correction;
X3: the air speed influence factor;
E: solar radiation correction;
X4: solar radiation factor of influence;
F: speed of a motor vehicle correction;
X5: speed of a motor vehicle factor of influence;
G: air inlet model amendment $$$$ amount;
X6: air inlet pattern factor of influence;
Suppose that now vehicle interior temperature is y, the reading of vehicle interior temperature acquisition module is y0;
Through revised vehicle interior temperature, be: y=y0+ Δ y.
Concrete correction need to be demarcated and obtain by experiment, and for ease of explanation, the utility model is enumerated following example, but any restriction that the utility model is not given an example by this.
If when front truck external environment temperature correction a is-2 degree, factor of influence x0 is 1; Leaving air temp correction b is-1 degree, and factor of influence x1 is 0.2; Blowing model amendment $$$$ amount c is 0, and factor of influence x2 is 0.01; Wind speed correction d is 0.5, and factor of influence x3 is 1; Solar radiation correction e is 2, and factor of influence x4 is 0.5; The factor of influence of other corrections is 0, according to formula, obtaining vehicle interior temperature static modification value is Δ y=1*-2+0.2*-1+0.01*0+1*0.5+0.5*2+0=0.7, suppose that now the reading of vehicle interior temperature acquisition module is y0=20, pass through revised vehicle interior temperature value y=y0+ Δ y=20+0.7=20.7 degree.
Should illustrate, dynamically amending unit 301 and static modification unit 301 alternation along with | the variation of Δ u| value, its correcting action is accompanied by the whole process that auto Air Conditioner control system is moved.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
