Method and system for automatically controlling an automotive HVAC unit
First Claim
1. A method for automatically controlling a heating, ventilating, and air conditioning (HVAC) unit of a vehicle, the HVAC unit having multiple electric motors for actuating multiple respective doors directing air flow through the HVAC unit and temperature of the air flow, the method comprising:
- sensing a plurality of temperatures;
determining a desired temperature and desired direction of air flow based on the plurality of temperatures; and
controlling the multiple electric motors so that their respective doors move at the same time while preventing preselected doors from operating at the same time, the multiple electric motors controlled based on the desired temperature and desired direction of air flow.

Abstract
A method and system for automatically controlling a heating, ventilating, and air conditioning (HVAC) unit of a vehicle includes multiple electric motors for actuating multiple respective doors directing air flow through the HVAC unit and temperature of the air flow. A plurality of sensors sense a plurality of temperatures. A controller determines a desired temperature and desired direction of air flow based on the plurality of temperatures. The controller also controls the multiple electric motors so that their respective doors move at the same time while preventing preselected doors from operating at the same time based on the desired temperature and desired direction of air flow.
