With certain delay.If for example, in the case of gentle external temperature, run suddenly due to air blower causes interior cabin more slowly
Temperature is raised, then this is recorded and by air adjustment control device by strengthening refrigeration come or by reduce air blower air inlet by again
The part of circulation compensates.However, it occurs have certain delay, the delay is eliminated by the present invention.
If only the suddenly change in response to vehicle supply voltage --- in other words, occur under Part II intensity
Or the change for not occurring in response to any slow change, for example occur during vehicle battery charging or appropriateness electric discharge
Change --- and perform the method, then it is sufficient for above-mentioned reason.
In the case where unexpected blower voltage changes, before and after the setting value of air blower air outlet temperature is according to voltage change
The magnitude of voltage of air blower, air blower intake air temperature, ambient air temperature and/or other measured values and change.
Being changed to the setting value of the air blower air outlet temperature of such degree causes air blower air outlet temperature due to carrying
The gas for supplying air blower is heated or is cooled to greater or lesser degree and/or is recycled due to air blower air inlet
Partial change and change.
Dependence of the setting value of air blower air outlet temperature to above-mentioned variable can be determined in advance as look-up table, the look-up table
With empirical data predefine or setting value it is necessary change before time point be in the motor vehicle it is available and
Storage is in the motor vehicle or in the air conditioning controller with function of motor vehicles.
In a preferred embodiment of the invention, in order to generate look-up table, according to minor function in vehicle in real time or
Predefine setting value：

The part that χ=air blower air inlet is recycled
(only fresh air=0...1=only has recycling)
Item in the square brackets of above-mentioned function represents air blower intake air temperature, and the T if χ=0i=Tambient, example
Such as, in the case of without air circulation in the vehicle of air adjustment or in the open vehicle with open top.
Specific embodiment
The explanation of exemplary embodiment is provided below.
Motor vehicles include air handling system, wherein interior cabin temperature can be selected either automatically or manually.The air adjustment system
System includes air blower, and the electro-motor of the air blower is driven by the electric current from vehicle power supply.For example due to beating
Open or close close current consumer or change current consumer state or because the failure or battery of any power components are filled
In the case that electric load changes in vehicle power supply caused by the quick change of electric current, there is provided to the vehicle power supply of air blower
Voltage may suddenly change.
Therefore the suddenly change of vehicle power supply voltage may cause the change of air handling system air outlet temperature, and this is not only not
Occupant's comfort level is influenceed to be also possible to enrage occupant sharply, reason is that the change is rendered as failure or due to by air adjustment system

May cause generation windshield atomization is frozen or also resulted on the evaporator of air handling system.In addition, by acceptable
Control deviation may damage the adjustment programme of air handling system.
Generally, automatic air regulating system is according to desired temperature and measured value --- cabin temperature and the sun in such as main flow
Irradiation --- the amount and temperature of the air-flow that adjustment is produced by air blower.Because air blower goes out caused by vehicle power supply voltage change
Any change of temperature degree recognizes by the slowly varying of automatic air regulating system reference measure value, but only with correspondingly
Slow way is compensated, only to there is occupant it may be found that uncomfortable temporary transient temperature change.
In the exemplary embodiment, it is worth to the second value different from the first value from first in response to supply voltage in vehicle
