FIELD: transportation.
SUBSTANCE: invention relates to a vehicle heating system. Following a vehicle shut down, when temperature of the windshield is lower than ambient dew point, heat is transferred from the powertrain of the vehicle to the windshield via a coolant. If powertrain temperature is higher than the windshield temperature, heat is transferred from ambient air to the windshield via the coolant, if the powertrain temperature is lower than the windshield temperature and ambient temperature is higher than the windshield temperature.
EFFECT: prevention of condensation on the windows of a shut-down and parked vehicle.
