The HVAC module analyzes input from the following major sources:
- Temperature, airflow direction, blower, A/C and RECIRC selection (made by the vehicle occupants)
- In-vehicle temperature sensor (non-hybrid)
- In-vehicle temperature and humidity sensor (hybrid)
- Ambient air temperature sensor
- Solar radiation sensor (sunload sensor)
- Vehicle speed
- Engine coolant temperature
- Occupant Classification Sensor (OCS) (hybrid only)
Using these inputs, the HVAC module determines the correct conditions for the following outputs:
- A/C compressor operation
- Blower motor speed
- RH and LH temperature blend door positions
- DEFROST/PANEL/FLOOR airflow mode door position
- Air inlet mode door position
