Example Embodiment

[0039] The present invention will be further described below in conjunction with accompanying drawing.

[0040] like figure 1 As shown, the vehicle automatic air-conditioning control method of the present invention comprises the following steps:

[0041] Step 1. Collect the temperature inside the car through the internal temperature sensor on the car, the sunshine sensor collects the light intensity signal, and the external temperature sensor collects the ambient temperature outside the car. Among them, the internal temperature sensor is arranged on the instrument panel, the sunlight sensor is arranged under the front windshield, and the external temperature sensor is arranged on the front collision beam.

[0042] Step 2. The electronic controller obtains the output value of the internal temperature sensor, the output value of the sunshine sensor, and the output value of the external temperature sensor, and uses the output value of the internal temperature sensor, the output ...

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...
