Automatic air conditioning system is that controller in HVAC control module (1) automatically controls in-car
temperature, fan speed, airflow outlet and so forth. Once users set up desired in-car temperature by temperature
selector of HVAC control module, the controller in HVAC control module detects in-car temperature, outside air
temperature, amount of sunlight, and engine coolant temperature by inside air temperature sensor (2), outside air
temperature sensor (3), sunload sensor (4), and ECT sensor (5). Then, controller of HVAC control module keeps
