ABSTRACT:
Method for controlling a HVAC system in a vehicular compartment includes monitoring temperature of an occupant in the compartment from a location apart from the occupant, and controlling the HVAC system based on the monitored temperature. Occupant temperature may be monitored by infrared sensors, each arranged in an orientation to receive electromagnetic radiation from one or more seating locations in which occupants are likely to be situated. The temperature in each seating location is independently monitored. The HVAC system is controllable for each seating location based on the monitored temperature in that area. When monitoring of temperature in an area in which a driver of the vehicle is likely to be situated indicates presence of the driver, and no other areas indicate presence of a human occupant, the HVAC system is controllable such that all heat or air-conditioning provided by the HVAC system is directed to the driver.
