Title: SYSTEMS AND METHODS FOR CABIN AIR QUALITY CONTROL
Abstract:
Methods and apparatus are provided for controlling an air quality within a passenger cabin (38). The method includes outputting one or more control signals, by a processor (20), to activate a motor (32) to generate an airflow stream for observation by a fine particulate matter sensor (36), the fine particulate matter sensor (36) generating sensor signals based on the observation; determining a concentration level of fine particulate matter in the airflow based on the sensor signals; and outputting one or more control signals to an air quality system (16) associated with the passenger cabin (38) to generate an airflow into the passenger cabin (38) based on the determined concentration level, the airflow into the passenger cabin (38) flowing through a fine particulate matter filter (50).
