Zusammenfassung:A vehicle heating, ventilation, and air conditioning (HVAC) system including a cabin air filter, a sensor for providing a sensor reading, and a controller for determining a feedback signal from the sensor reading, wherein the controller determines a cabin air filter expected blockage level from the feedback signal. The feedback signal relates to a usage modifier of the cabin air filter, wherein the controller at east partially adjusts the estimated usage the cabin air filter from the usage modifier.
