The invention discloses an intelligent control method and system for internal and external circulation of a vehicle air conditioner, and belongs to the field of vehicle air conditioner control. The method comprises the following steps: S1, collecting vehicle sensor data; s2, calculating the fogging probability of glass in the vehicle according to the vehicle sensor data; s3, when the fogging probability is smaller than or equal to a preset probability threshold value, the relative humidity of air in the vehicle is obtained; when it is detected that the relative humidity of the air in the vehicle is smaller than or equal to a preset humidity threshold value, the air conditioner enters a partial internal circulation mode; and S4, in the partial internal circulation mode, the external environment temperature of the automobile is obtained, and when the external environment temperature of the automobile is smaller than or equal to a preset temperature threshold value, the internal and external circulation proportion of the air conditioner is controlled according to preset calibration data. Through intelligent control over the internal and external circulation proportion of the air conditioner, the power consumption of the whole vehicle is reduced, the endurance is improved, and the air conditioner is suitable for being used in winter.

    本发明公开了一种车用空调内外循环的智能控制方法及系统,属于车辆空调控制领域。所述方法包括以下步骤:S1、采集车辆传感器数据;S2、根据所述车辆传感器数据计算车内玻璃起雾概率;S3、当所述起雾概率小于等于预设概率阈值时,获取车内空气相对湿度;当检测到所述车内空气相对湿度小于等于预设湿度阈值时,空调进入部分内循环模式;S4、在所述部分内循环模式下,获取车外环境温度,当所述车外环境温度小于等于预设温度阈值时,根据预设的标定数据控制空调内外循环比例。本发明通过空调内外循环比例的智能控制,降低了整车功耗,提高了续航,适用于冬季空调的使用。
