At present along with the development of auto trade with to the improving constantly of comfort requirement in the car, increasing automatic air-conditioning system replaces manual air conditioning system to be applied on the automobile.
Auto Air Conditioner relies on air-conditioner controller, by the algorithm that reads in the multiple sensors signal and design, controls temperature damper, thereby automatically adjusts air temperature.Temperature damper needs a cover automatic control algorithm, makes leaving air temp control energy fast quasi-stationary, and fast speed is followed the variation of environment and user's setting in dynamic process, and temperature precise control pulsation-free is kept.
Summary of the invention
Based on this, be necessary to provide a kind of leaving air temp that makes in dynamic process, to follow rapidly object variations, temperature automobile air conditioner air outlet temperature-controlled process accurate and that keep reposefully during stable state.
A kind of automobile air conditioner air outlet temperature-controlled process comprises step: determine a target leaving air temp according to user's setting and car internal and external temperature at least; Calculate the first temperature damper position according to described target leaving air temp, evaporator temperature and cooling-liquid temperature; Calculate the second temperature damper position according to described target leaving air temp and actual leaving air temp; According to the first damper positions and the second temperature damper location positioning temperature damper position; And the temperature damper that utilizes described temperature damper position control air conditioning for automobiles.
In a preferred embodiment, described evaporator temperature is from the temperature sensor that is installed in the evaporator lower surface, is used for measuring the air themperature of evaporator of flowing through.
In a preferred embodiment, described cooling-liquid temperature is from the pipeline that is installed in engine-cooling system, wherein the refrigerant fluid heating core body of flowing through and being installed in air-conditioning box inside by a pipeline.
In a preferred embodiment, described leaving air temp is used for measuring the leaving air temp of air-conditioning box from the temperature sensor of the air outlet pipeline the inside that is installed in air-conditioning box.
In a preferred embodiment, when calculating described the second temperature damper position, determine the proportional integral (PI) of the second temperature damper position according to the difference between target leaving air temp and the leaving air temp.
The present invention calculates the first damper positions and the second damper positions according to car internal and external condition, user's setting, evaporator temperature and cooling-liquid temperature, integrate these two damper positions as the position output of temperature damper, thereby make leaving air temp fast speed in dynamic process follow object variations, accurate and the pulsation-free maintenance of temperature during stable state, thereby guarantee the comfortable of vehicle interior temperature, reduce user's operation.
Description of drawings
Fig. 1 is the block diagram that the present invention of an embodiment is used for calculating air temperature.
Fig. 2 is the diagram of circuit that the present invention of an embodiment is used for automatic air condition accounting temperature air door.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing automobile air conditioner air outlet temperature-controlled process of the present invention is described in further detail.
Automobile air conditioner air outlet temperature-controlled process of the present invention is used for obtaining suitable leaving air temp.As shown in Figure 1, air-conditioner controller 5 reads in sunlight strength 1 by the sensor that is installed in the car, external temperature 2 and vehicle interior temperature 3, and (for example can comprise according to the sunlight strength that reads in, external temperature, vehicle interior temperature and user's setting, temperature arranges, pattern setting, inner-outer circulation setting, the man-machine interaction settings such as wind speed of blast blower arranges) 4, calculate in the car of sening as an envoy to and reach the needed target leaving air temp of a home from home (hereinafter can describe calculated case in detail) 6.That is: target leaving air temp=h (user arrange, sunlight strength, external temperature, vehicle interior temperature), wherein parameter needs that comprise of h are determined in conjunction with vehicle condition and the experiment of reality.This target leaving air temp 6 can be in the constant situation of user's settings Following Car internal and external temperature value variation and change.Understandable, when calculating the target leaving air temp, the parameter of reference can be adjusted to some extent, for example not with reference to sunlight strength.
The flowcharting of Fig. 2 the present invention be used for the step and method of accounting temperature air door.The target leaving air temp 6, evaporator temperature 7 and the cooling-liquid temperature 8 that wherein need to obtain according to Fig. 1 calculate the first temperature damper position 10, calculate the second temperature damper position 11 according to current target leaving air temp 6 and actual leaving air temp 9.
Evaporator temperature is from the temperature sensor that is installed in the evaporator lower surface, is used for measuring the air themperature of evaporator of flowing through.Cooling-liquid temperature is from the pipeline that is installed in engine-cooling system, wherein the refrigerant fluid heating core body of flowing through and being installed in air-conditioning box inside by a pipeline.
First temperature damper position=f (target leaving air temp, evaporator temperature, cooling-liquid temperature)
=K (target leaving air temp-evaporator temperature)/(cooling-liquid temperature-evaporator temperature);
K wherein needs to demarcate according to concrete a/c system.
Leaving air temp is used for measuring the leaving air temp of air-conditioning box from the temperature sensor of the air outlet pipeline the inside that is installed in air-conditioning box.
Second temperature damper position=g (target leaving air temp, leaving air temp), wherein g is poor according between target leaving air temp and the leaving air temp, determines the proportional plus integral control method of the second temperature damper position.In a preferred embodiment, second temperature damper position=Kp* (target goes out air temperature – leaving air temp)+Ki* ∑ (target goes out air temperature – leaving air temp).Kp wherein and Ki need to demarcate according to concrete a/c system.
Control at last A/C according to the position 12 of the first damper positions 10 and the second temperature damper position 11 definite temperature dampers, control temperature damper as output.In one preferred embodiment, temperature damper position=the first temperature damper position+the second temperature damper position.
Control method according to aforesaid automobile air conditioner air outlet temperature of the present invention, User arranges, the condition that car is interior and car is outer, calculating makes vehicle interior temperature reach comfortable needed target leaving air temp, according to the target leaving air temp, evaporator temperature and cooling-liquid temperature calculate the first damper positions, calculate the second damper positions according to the gentle sensor of target air-out, integrate these two damper positions as the position output of temperature damper, make actual leaving air temp equal the target leaving air temp, make leaving air temp fast speed in dynamic process follow object variations, accurate and the pulsation-free maintenance of temperature during stable state, make when reaching a home from home in the car, also reduced user's operation.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
