Vehicle ventilation control method, storage medium and system

The invention provides a vehicle ventilation control method, a storage medium and a system. The method comprises the following steps: acquiring an air pollution index of an external environment of a vehicle; acquiring an opening value of a vehicle external circulation air door; the air pollution index represents air pollution, and when the opening value of the external circulation air door of the vehicle is larger than zero, if the air pollution index is smaller than or equal to a first index, reducing the opening value of the external circulation air door. According to the method, when the opening value of the external circulation air door is larger than zero, if the air pollution index in the external environment of the vehicle shows air pollution, the opening value of the external circulation air door is reduced, so that polluted air enters the vehicle as little as possible, and the air quality in the vehicle can be improved. 本申请提供一种车辆通风换气控制方法、存储介质和系统，其中的方法包括：获取车辆外部环境的空气污染指数；获取车辆外循环风门的开度值；所述空气污染指数表示空气污染，同时
