The invention discloses an automatic demisting energy-saving control method and system for an automobile air conditioner, and relates to the technical field of automobile air conditioner system control. The method comprises the following steps: acquiring temperature and humidity data in a vehicle, and calculating a fogging probability according to the temperature and humidity data; dividing the fogging probability into a plurality of grades according to the fogging risk, and performing fogging probability grade correspondence according to the current fogging probability; and a defogging algorithm is selected in combination with the fogging probability grade and the number of passengers, when the lowest fogging probability grade is reached, the compressor is controlled not to be started at first according to the defogging algorithm, but the correlation amount is compensated, and whether the compressor is started or not is decided according to the fogging probability trend subsequently. According to the method, frequent starting of the compressor is avoided through measures of increasing the dew point temperature, dividing the fogging risk probability grade and the like, and the purposes of saving fuel oil, saving electric energy and reducing noise in the vehicle are achieved.
本发明公开了一种汽车空调自动除雾节能控制方法及系统,涉及汽车空调系统控制技术领域。该方法包括步骤:获取车内温湿度数据,根据温湿度数据计算得到起雾概率;根据起雾风险大小将起雾概率分成多个等级,并根据当前起雾概率进行起雾概率等级对应;结合起雾概率等级与乘员数量选择除雾算法,其中,当达到最低的起雾概率等级时,根据除雾算法控制先不开启压缩机,但是对关联量进行补偿,后续根据起雾概率趋势决定是否开启压缩机。本发明通过提高露点温度、划分起雾风险概率等级等措施,避免压缩机频繁开启,达到了节省燃油、节省电能以及降低车内噪音的目的。
