The invention discloses a control method for an automatic defogging control system of an automobile. The control system includes a defogging controller. The signal input end of the defogging controller communicates with an image recognition device through an image processor. The terminals are respectively connected with a defogging mode switch, a blower, and an air outlet angle adjustment device; the control method includes obtaining the position of the driver's eyes through the automatic defogging control system to determine the first area that affects the driver's sight, reducing the first area, and the area is more accurate and real for the driver. When defogging, make the defogging air outlet face the area with the smallest clarity in the first area, so that the clarity of the first area can meet the requirements more quickly. When the clarity of the first area meets the requirements, the wind speed of the blower is reduced when defogging the non-first area, thereby reducing the demisting noise and power consumption.
Description
technical field [0001] The invention relates to the technical field of automobile defogging, in particular to a control method of an automobile automatic defogging control system. Background technique [0002] When the air humidity is high, it is easy to fog up on the front windshield and side windows. The current technical solution is to manually adjust the air conditioner to the defrosting and defogging mode, and adjust the air volume according to the concentration and distribution area of the fog. In winter, heating and defogging; in other weathers, cooling and defogging are used. In order to defog as soon as possible, so that the fog layer on the glass does not affect the driver's vision, it is generally defogged with a large air volume, and the air conditioner rotates at a high speed, and the noise also increases. After the fog on the front windshield does not affect driving, the driver manually reduces the air volume of the air conditioner. The whole adjustment pr...
