Method and system for controlling air conditioning mode damper of automobile

Abstract

The invention provides a method for controlling an air conditioning mode damper of an automobile. The method comprises the steps of (a), initializing; (b), acquiring a signal, wherein the acquired signal includes environmental temperature, solar radiation intensity, indoor temperature of the automobile, and set air conditioning temperature; (c) accurately calculating the process umber according to the environmental temperature, solar radiation intensity, indoor temperature of the automobile, and set air conditioning temperature; (d) enabling the mode damper to select one of a face blowing mode, face / feet blowing mode, feet blowing mode, and feet blowing / defrosting mode to work according to the process number and related set parameters in initializing; (e) returning to step (b) to enter the next process cycle. The method has the beneficial effects that the process number can be accurately calculated, and thus the comprehensive environmental condition can be accurately and objectively reflected; in addition, the feet blowing / defrosting mode is added for the mode damper, so that the automatic control range can be expanded, and the automation degree is increased.

Description

technical field [0001] The invention relates to a control method and a control system for a mode damper of an automobile air conditioner, belonging to the field of automobile air conditioners. Background technique [0002] With the rapid development of the automobile industry, a comfortable driving and riding environment has become an issue that automobile manufacturers pay more and more attention to, so automatic air conditioning in automobiles is becoming more and more important. The automatic algorithm of automobile air conditioner has been developed rapidly in the past few years, and the basic control logic has been formed. [0003] However, in the prior art, only a few parameters (such as ambient temperature) are often used as the basis for judging the position of the mode damper, but this control method is obviously inaccurate, because the comprehensive expression of the ambient temperature is not only related to the ambient temperature , also depends on other paramet...

Problems solved by technology

[0003] However, in the prior art, only a few parameters (such as ambient temperature) are often used as the basis for judging the position of the mode damper, but this control method is obviously inaccurate, because the comprehensive expression of the ambient temperature is not only related to the ambient temperature , also depends on other parameters

[0004] In addition, the automobile air conditioning mode damper in the prior art usually only has face blowing mode, face blowing / foot blowing mode and foot blowing mode, and the range of this automatic control is relatively small
