The invention discloses an intelligent control method for the fresh air proportion of an automobile cabin, which comprises the following steps: controlling an air conditioner ventilation mode based on the temperature inside and outside an automobile under the refrigeration working condition of the automobile, detecting whether the CO2 concentration in the cabin reaches the CO2 concentration upper limit value in real time when the air conditioner ventilation mode is a full internal circulation mode, and if yes, executing the step 2; if yes, fresh air is controlled to be introduced according to the minimum fresh air proportion b or slightly larger than the minimum fresh air proportion b; wherein the minimum fresh air proportion is calculated based on the number of passengers. According to the method, the fresh air inlet of the air conditioner is controlled based on the minimum fresh air proportion calculated by the passengers, so that the energy consumption caused by too large air volume is reduced, and the energy consumption is reduced on the premise of ensuring the CO2 concentration in the vehicle and avoiding fogging.

    本发明公开了一种汽车座舱新风比例智能控制方法,在汽车制冷工况下,基于车内外温度控制空调通风模式,当空调通风模式为全内循环模式时,实时检测舱内CO2浓度是否达到C02浓度上限值,若是,则按照最低新风比例b或略大于最低新风比例b控制引入新风;其中最小新风比例基于乘员人数计算得到。本发明通过基于乘员计算得到的最小新风比例来控制空调的新风进风从而减少风量过大造成的能耗,在保证车内CO2浓度和不起雾的前提下减少能耗。
