The invention provides a vehicle-mounted air conditioner internal and external circulation automatic control method based on vehicle detection, which comprises the following steps: step S10, in a vehicle driving process, a vehicle-mounted camera acquires surrounding images and identifies the surrounding images; s11, when it is detected that the vehicle of the specific vehicle type exists in the surrounding vehicles, the vehicle-mounted air conditioner is controlled to be in the internal circulation state; s12, the current starting time and the current vehicle speed of the vehicle are detected; s13, when the starting time of the vehicle exceeds the preset time and the current vehicle speed is lower than the preset vehicle speed threshold value, the vehicle density of a specific area in front of the vehicle is calculated and compared with a preset density threshold value; and S14, when the vehicle density is larger than or equal to the preset density threshold value, the vehicle-mounted air conditioner is controlled to be in the internal circulation state. The invention further discloses a corresponding system. By implementing the method and the device, the state of the vehicle-mounted air conditioner can be adaptively controlled according to the environmental conditions (the type of the nearby vehicle, the vehicle speed, the density of the surrounding vehicle and the like), the air quality in the vehicle can be improved, and the safety can be improved.

    本发明提供一种基于车辆检测的车载空调内外循环自动控制方法,包括:步骤S10,在车辆行驶过程中,车载摄像头获取周围的图像并进行识别;步骤S11,在检测到周围车辆中存在特定车型的车辆时,控制车载空调处于内循环状态;步骤S12,检测车辆当前已启动时间以及当前车速;步骤S13,当车辆已启动时间超过预定时间且当前车速低于预定车速阈值时,计算车辆前方特定区域的车辆密度并与一预定的密度阈值进行比较;步骤S14,在车辆密度大于或等于预定的密度阈值时,控制车载空调处于内循环状态。本发明还公开了相应的系统。实施本发明,可以根据环境状况(附近车辆的类型、车速、周围的车辆密度等),自适应地控制车载空调的状态,能够提高车内空气质量以及提高安全性。
