The invention discloses an automatic demisting method and an automatic demisting device, and relates to the technical field of air conditioning equipment, and the automatic demisting method of a vehicle comprises the following steps: emitting detection light from a front windshield in the vehicle through a light source, obtaining a first brightness value of the detection light through a first optical sensor, and obtaining a second brightness value of the detection light through a second optical sensor; acquiring a second brightness value of ambient light near the first optical sensor through a second optical sensor, and calculating the transmittance of the front windshield through the brightness value of the light source, the first brightness value and the second brightness value; comparing the transmittance with a preset transmittance threshold; and the operation state and operation parameters of the air conditioner are adjusted according to the comparison result. The fogging degree is judged by detecting the transmittance of the front windshield, so that the air conditioner is automatically turned on to carry out automatic defogging operation when normal driving is influenced by the fogging, green drivers and drivers who do not understand an air conditioning system and a fogging principle can also carry out defogging, the front windshield is kept clear and visible, and the driving safety is improved.
本发明公开了一种自动除雾方法及自动除雾装置,涉及空调设备技术领域,车辆的自动除雾方法,包括以下步骤:通过光源自车内向前挡风玻璃发出检测光线,通过第一光学传感器获取检测光线的第一亮度值,通过第二光学传感器获取所述第一光学传感器附近的环境光的第二亮度值,通过光源的亮度值、第一亮度值和第二亮度值计算前挡风玻璃的透过率;比对透过率与预设透过率阈值;根据比对结果调整空调的运行状态及运行参数。本发明通过检测前挡风玻璃的透过率判断起雾程度,从而在雾气影响正常驾驶时自动打开空调进行自动除雾作业,使得新手驾驶员以及不懂空调系统和起雾原理的驾驶员也可以进行除雾,保持前挡风玻璃的清晰可见,提高了驾驶安全性。
