Abstract

Methods and apparatus are provided for controlling air quality in a passenger cabin. The method includes outputting, by a processor, one or more control signals to activate a motor to generate airflow to be observed by a fine particulate matter sensor, the fine particulate matter sensor generating a sensor signal based on the observations; determining a concentration of fine particulate matter in the airflow based on the sensor signal and outputting, based on the determined concentration level, one or more control signals to an air quality system associated with the passenger cabin to generate airflow into the passenger cabin that flows through the fine particulate matter filter.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application is based on U.S. national phase entry under 35 U.S.C. §371 of International Application No. PCT / CN2016 / 075142, filed March 1, 2016, published under PCT Section 21(2), and therefore will Its entire contents are incorporated by reference. technical field [0003] The present disclosure relates generally to vehicles, and more particularly to systems and methods for air quality control in passenger cabins of vehicles. Background technique [0004] Due to the characteristics of the environment, air quality may vary as it travels through certain environments. For example, air quality in densely populated areas may be different from air quality in rural areas. Also, the air quality in industrial areas may be different from that in agricultural areas. In certain environments, there may be levels of fine dust or particulate matter in the air surrounding the vehicle that can enter the passenger cabin of the ve...
