Embodiment Construction

[0038] The present invention discloses a method for controlling the circulating damper of an automobile air conditioner. Before describing the present invention in detail, the relevant terms involved in the present invention are first explained as follows:

[0039] ProgNo: program number, which means the comprehensive expression of the current environment;

[0040] PNFixed: constant compensation item of program number;

[0041] PNOutAmb: ambient temperature weighting coefficient;

[0042] OutAmb: ambient temperature, that is, an accurate ambient temperature value calculated by measurement or other means; preferably, the ambient temperature is a calibrated ambient temperature calculated by integrating various related parameters;

[0043] PNSolarLoad: the weighting coefficient of the solar radiation intensity;

[0044] SolarLoad: solar radiation intensity, which can be measured by the solar radiation intensity sensor;

[0045] IntAirTmp: interior temperature of the vehicle; ...

Abstract

A control method for an automobile air conditioner circulating air door comprises the following steps of (a) initialization, (b) signal obtaining, (c) calculation of the program number according to obtained signals, wherein the program number is the comprehensive expression quantity of the current environment, (d) setting of internal circulation or external circulation according to the magnitude relationship between the program number and relevant set parameters, (e) judgment of the magnitude relationship between automobile speeds and an automobile speed critical value to determine whether internal circulation needs to be set forcedly, and (f) redoing of the step (b), and starting of the next program loop. The control method has the advantages that internal circulation and external circulation can be judged more accurately according to the program number which is obtained through calculation of various parameters, such as environment temperature, sun radiation intensity, automobile speeds, temperature in an automobile and the control objective of the temperature in the automobile. In addition, whether internal circulation needs to be set forcedly is determined by judging whether the automobile speed is too low, pre-judging of the outside air quality can be achieved, and high intelligence is achieved.

Description

technical field [0001] The invention relates to a control method and a control system for a circulating 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] The internal and external circulation is an important system of automobile air conditioning. The air conditioner controller can control the entry of outdoor fresh air in the case of external circulation; compared with the external circulation, the air conditioner controller can heat up or cool down more quickly in the case of internal ...
