Abstract
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 feedback signal relates to a usage modifier of the cabin air filter.
Claims20
A vehicle heating, ventilation, and air conditioning (HVAC) system comprising:
- 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 feedback signal relates to a usage modifier of the cabin air filter.
1 more element
A method for determining a usage level of a cabin air filter comprising:
- providing a heating, ventilation, and air conditioning (HVAC) system comprising a cabin air filter, a sensor for providing a sensor reading, and a controller operably coupled to the sensor;
- receiving a reading from the sensor;
- and
- using the reading from the sensor to determine a feedback signal with the controller, wherein the feedback signal relates to a usage modifier of the cabin air filter.
1 more element
A vehicle heating, ventilation, and air conditioning (HVAC) system comprising:
- a cabin air filter;
- an ambient air temperature sensor;
- a cabin air temperature sensor;
- and
- a controller operably coupled to the ambient air temperature sensor and the cabin air temperature sensor, wherein the controller is configured to provide a feedback signal based on the ambient air temperature, the cabin air temperature, a cabin air temperature setting, and an air distribution mode of the HVAC system, wherein the feedback signal relates to an usage modifier of the cabin air filter.
