Method for controlling automatic air conditioning for automobile

Abstract

The invention discloses a method for controlling an automatic air conditioning for an automobile. The method comprises the following steps of 1, acquiring the temperature in the automobile by using an inner temperature sensor in the automobile, acquiring an illumination intensity signal by using a sunlight sensor, and acquiring ambient temperature outside the automobile by using an outer temperature sensor; 2, acquiring an output value of the inner temperature sensor, an output value of the sunlight sensor and an output value of the outer temperature sensor by using an electronic controller, and calculating a TAO value according to the output value of the inner temperature sensor, the output value of the sunlight sensor, the output value of the outer temperature sensor, and a temperature value set by a user; 3, automatically controlling the temperature mixing air door opening, the air volume, air outlet modes and internal and external circulation by using the electronic controller according to the TAO value obtained in the step 2, wherein the step 3 comprises the following substeps of 3a, controlling the temperature mixing air door opening; 3b, controlling the air volume; 3c, controlling the switching of the air outlet modes; 3d, controlling the switching of internal and external circulation. According to the method, the indoor temperature of the automobile can be stabilized near the value expected by the user, and ultralow or ultrahigh temperature can be avoided.

Description

technical field [0001] The invention belongs to the control technology of an air conditioner for vehicles, and in particular relates to a control method for an automatic air conditioner for vehicles. Background technique [0002] With the development of the automobile industry and the improvement of people's pursuit of automobile comfort, the performance of automobile air-conditioning systems has attracted more and more attention from the majority of users. The weather in summer is hot, and the ambient temperature outside the vehicle will fluctuate (the surrounding temperature is different when the vehicle is driving on a high-speed or urban road). In addition, compared with autumn in summer, people's demand for cooling is also different. Traditional air conditioning systems rely on manual adjustment, and the adjustment gear corresponds to a certain target temperature. This will easily cause the temperature in the car to keep dropping and become unstable. When the user feel...
