Abstract:
A heating, ventilating, and air conditioning (HVAC) system has a steerable outlet for directing a stream of treated air into a passenger compartment of a vehicle. A thermographic imager is configured to capture thermographic images covering a fixed region within the passenger compartment in which an occupant is potentially located. The HVAC control circuit is configured to a) compress a thermographic image to a temperature map representing pixels of the thermographic image falling within a predetermined temperature range corresponding to the occupant, b) filter the temperature map according to a sliding window to coalesce continuous regions of pixels on average falling within the predetermined temperature range, c) quantify an area for each continuous region, d) locate a centroid of a continuous region having a largest area, and e) aim the steerable outlet toward the centroid.
