Automatic automobile air conditioner control method

Abstract

An automatic automobile air conditioner control method comprises the following steps: (a), starting a program; (b), initializing; (c), receiving signals; (d), calculating the number of indoor temperature control objectives and programs of an automobile; (e), determining the mode ventilation door output value; (f), determining the circulating ventilation door output value; (g), calculating the output rotating speed of an air blower; (h), calculating the position of a temperature ventilation door; (i), balancing energy, wherein the automobile indoor energy variation is equal to the sum of energy generated from solar radiation, energy generated from the heat exchange between the automobile body and the environment, energy generated from the heat exchange of an evaporator, energy generated from the heat exchange of a heating core, energy brought by an engine, actual energy brought into the interior of the automobile by a heat source and rectified energy; (j), calculating the automobile indoor temperature; (k), returning to the step (c), and performing the next circulating calculation until the calculated value of the automobile indoor temperature is close to the automobile indoor temperature control target. The automatic automobile air conditioner control method has the benefits that the energy balance algorithm is totally based on the most fundamental factor causing the temperature variation, and can accurately realize the temperature and comfort degree control.

Description

technical field [0001] The invention relates to an automobile automatic air-conditioning control method, which belongs to the field of automobile air-conditioning. 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 control principle of the existing automatic air conditioner for automobiles is mainly to adjust the position of the mixing damper according to the temperature difference between the interior of the vehicle and the set temperature. The usual methods are as follows: [0003] One is the direct feedback control of the temperature sensor in the vehicle interior, that is, the temperature input into the vehicle interior is determined by installing the temperature sensor in the vehicle interior to represent the temperature of the...

AI Technical Summary

Problems solved by technology

from figure 2 It can be seen from the figure that the cold and heat input into the car interior is not linearly related to the car interior temperature, ambient temperature, and sunlight radiation. If the linear adjustment is followed, it will inevitably lead to inaccurate temperature regulation and a decrease in passenger comfort.
