The invention relates to the technical field of vehicle ventilation, in particular to a method for automatically switching internal and external circulation of an air conditioner. Judging based on the real-time condition data of the surrounding environment of the vehicle to obtain a data judgment result; generating a control operation command and a control operation command based on the data judgment result; controlling a circulation mode and a vehicle window switch to perform switching operation based on the control operation command; according to the method, real-time condition data around the vehicle is obtained by detecting the environment around the vehicle and the air from the air inlet of the vehicle, judgment is performed based on the real-time condition data around the vehicle and the preset threshold value, the actual condition of the vehicle is detected, and if the data judgment result is that the preset threshold value range is exceeded, the alarm prompt is given out. And if yes, the control circulation module is switched into an internal circulation mode, so that the problem of poor in-vehicle air quality caused by untimely switching in daily driving is solved.
本发明涉及车辆通风技术领域,具体涉及一种空调内外循环自动切换的方法,识别车辆周围环境的实时情况数据;基于车辆周围环境的实时情况数据进行判断,得到数据判断结果;基于数据判断结果生成控制操作命令和控制操作命令;基于控制操作命令控制循环模式和车窗开关进行切换操作;基于控制操作命令发出告警提示,本方法通过对车辆周围环境及车辆进气口出的空气进行检测得到车辆周围实时情况数据,基于车辆周围实时情况数据与预设阈值进行判断,检测车辆的实际情况,若数据判断结果为超出预设阈值范围,则控制循环模块切换为内循环模式,从而解决了在日常行车中由于切换不及时导致车内空气质量差的问题。
