The invention discloses a method and device for controlling internal and external circulation of a vehicle-mounted air conditioner. The method comprises the steps that after a traffic light signal ora brake light signal in front of a target vehicle and a vehicle speed signal or a gear signal of the target vehicle are obtained, whether the current environment of the target vehicle is a red light parking scene or not can be judged according to the traffic light signal or the brake light signal and the vehicle speed signal or the gear signal, and if yes, the air conditioner of the target vehicleis controlled to be switched from outer circulation to inner circulation; and if not, the air conditioner of the target vehicle is controlled to continue to keep the outer circulation state. According to the invention, whether the vehicle is in the red light parking scene or not is accurately judged according to the state of the traffic light or the brake light in front of the vehicle and the auxiliary information such as the vehicle gear or the vehicle speed state, and then internal and external circulation of the air conditioner is controlled to be automatically switched according to the judgment result, so that the air conditioner control comfort can be improved, and the driving safety and the user experience of passengers are improved.

    本申请公开了一种车载空调内外循环的控制方法及装置,该方法包括:在获取到目标车辆前方的红绿灯信号或制动灯信号、以及目标车辆的车速信号或者目标车辆的档位信号后,可以根据该红绿灯信号或制动灯信号、以及车速信号或者档位信号,判断出目标车辆当前所处环境是否为红灯驻车场景,若是,则控制目标车辆的空调由外循环切换到内循环;若否,则控制目标车辆的空调继续保持外循环状态。可见,本申请先根据车辆前方的红绿灯或制动灯状态、以及车辆档位或车速状态等辅助信息来精确判断出车辆是否处于红灯驻车场景,然后再根据判断结果,控制空调内外循环自动切换,从而可以提升空调控制的舒适性,提高了行车安全性以及乘车人员的用户体验。
