Abstract
A vehicle glass heating system may include a vehicle glass having two or more electrically heated zones. The system may also have a controller, which determines an output based on an input signal and selectively actuates at least a portion of the heated zones to heat the vehicle glass according to the output.

20. A method, comprising:
-
determining, by a controller based on comparing a fogging probability indicative of a fogging risk in a zone of a vehicle glass to a fogging risk threshold, a change in at least one of a demist flow and an electrical heating for the zone to at least one of reduce the fogging risk and reduce energy usage; and selectively providing an output to adjust at least one of the demist flow and the electrical heating to the zone of the vehicle glass when the change is warranted.
