Abstract
A method of controlling a vehicle having a retractable bellypan and a heating, ventilation and air conditioning (HVAC) system determining a condenser temperature of a condenser of the HVAC system, comparing the condenser temperature to a temperature threshold and controlling a bellypan opening in response to comparing.
Claims20
A method of controlling a vehicle having a retractable bellypan and a heating, ventilation and air conditioning (HVAC) system comprising:
- determining a condenser condition of a condenser of the HVAC system or an engine coolant temperature;
- comparing the condenser condition to a condition threshold or the engine coolant temperature to a coolant threshold;
- and
- controlling a retractable element of a bellypan opening from an open position allowing airflow through the bellypan opening to a closed position preventing airflow through the bellypan opening in response to the comparing.
