The invention relates to an automatic demisting grade obtaining method, and belongs to the technical field of new energy automobile thermal management, and the method comprises the following steps: S1, obtaining an environment temperature, a glass temperature, a dew point temperature and humidity; s2, according to different environment temperature intervals, multiplying different calibration initial Tbase values by a correction coefficient K value of the environment temperature to obtain an initial T value; s3, compensating the initial T value in a specific scene by using the humidity value; s4, the initial T value of the vehicle in the low-speed state is compensated through the vehicle speed; s5, compensating the initial T value through the glass temperature; and S6, comparing a difference value obtained by subtracting the dew point temperature from the glass temperature with the compensated T value, and judging a corresponding interval to obtain a corresponding fogging grade.

    本发明涉及一种自动除雾等级获取方法,属于新能源汽车热管理技术领域,包括以下步骤:S1:获取环境温度、玻璃温度、露点温度和湿度;S2:根据不同的环境温度区间,使用不同标定初始T_base值与环境温度的修正系数K值相乘,得到初始T值;S3:利用湿度值在特定场景下给初始T值进行补偿;S4:通过车速补偿车辆在低速状态的初始T值;S5:通过玻璃温度对初始T值进行补偿;S6:通过玻璃温度减去露点温度的差值与补偿后的T值进行比较,判断相应的区间,得到相应的起雾等级。
