The invention relates to a method for operating a vehicle-mounted air conditioning system of a motor vehicle and a demisting system. The method comprises the following steps: 1) acquiring the ambient temperature around the motor vehicle; 2) acquiring the current speed of the motor vehicle; (3) air duct control parameters are determined according to the obtained environment temperature and the vehicle speed; (4) the vehicle-mounted air conditioner is switched into an internal ventilation mode or an external ventilation mode according to the determined ventilation duct control parameters; 5) opening a ventilating duct in a windshield glass area for demisting; wherein the step 1) and the step 2) can be executed in parallel or in an inverted sequence. By means of the method and the system, one or more of the environment temperature, the humidity, the automobile speed and the humidity signal of the windshield glass area are comprehensively evaluated, and the internal ventilation, the external ventilation, the air duct and the air conditioner of the automobile are intelligently switched based on the evaluation result, so that manual operation of a driver is not needed; therefore, harmful gas is prevented from flowing into the automobile while the windshield is prevented from fogging.

    本发明涉及一种用于运行机动车车载空调系统的方法及除雾系统,该方法包括以下步骤:1)获取机动车周围的环境温度;2)获取机动车当前的车速;3)根据所获取的环境温度和车速确定风道控制参数;4)根据所确定的通风道控制参数将车载空调切换为内通风或外通风模式;5)打开风挡玻璃区域的通风道进行除雾;其中,步骤1)和2)可以并行或者颠倒顺序地执行。借助于根据本发明的方法和系统,通过对环境温度、湿度、车速和风挡玻璃区域的湿度信号中的一项或多项进行综合评估,并且基于评估结果智能切换汽车的内、外通风,风道和空调,无需驾驶员手动操作,从而在防止风挡结雾的同时也防止有害气体流入车内。
