Description

In-vehicle air environment control method and system Technical Field The invention relates to the technical field of intelligent network automobiles, in particular to a method and a system for controlling an air environment in an automobile. Background With the development of intelligent cabins of automobiles, environmental comfort and health in automobiles are increasingly emphasized. Especially for passengers with allergic constitution or respiratory diseases, how to avoid exposure to high pollution or high allergen environment during driving becomes an important user demand. Common in the prior art are automotive automatic air conditioning and AQS (air quality system). The system typically includes an air quality sensor (primarily for detecting PM2.5 or NOx) located at the front of the vehicle, which is connected to the air conditioning control system. When the sensor detects that the concentration of the external air pollutants is increased, the system automatically switches the air conditioning circulation mode from the external circulation mode to the internal circulation mode, and activates an air conditioning filter element (usually a common dust filter element or a primary activated carbon filter element) to filter so as to prevent the external pollutants from entering the vehicle. The disadvantage of this prior art is that: 1. Reaction hysteresis this scheme is a "passive reaction" mode. The system takes action only after the sensor has detected the contaminant directly when the vehicle has been driven into the contaminated area. At this point, part of the contaminants may have entered the cabin, too late for the sensitive population; 2. the sensing dimension is single, the sensor usually only detects limited pollutant types (such as PM 2.5), can not effectively identify finer particles such as pollen, specific allergens and the like, can not monitor the concentration of CO2 in a vehicle, and can cause the air in the vehicle to be clunked after being circulated for a long time; 3. The protection is indiscriminate in that the system provides uniform air treatment for all passengers in the vehicle, and cannot provide local and enhanced protection for passengers with special requirements (such as severe allergy). Disclosure of Invention The invention provides an in-vehicle air environment control scheme, which aims to solve the problem that the existing in-vehicle air management system is delayed in protection due to passive reaction, solve the problem that the existing system cannot comprehensively monitor various allergens and harmful substances due to single sensor type, and solve the problem that the existing system cannot provide personalized and local reinforced protection for specific passengers.
