Abstract
A vehicle heating and air conditioning system basically includes an interior/exterior air introducing structure, a heating device, a driving end time acquiring section and an interior/exterior air switching control section. The interior/exterior air introducing structure switches the flow of cabin intake air between an interior air recirculation mode and an exterior air introducing mode. The heating device heats the cabin intake air being introduced by the interior/exterior air introducing structure. The driving end time acquiring section estimates a driving end time corresponding to a point in time at which driving of a vehicle is predicted to end. The interior/exterior air switching control section switches the interior/exterior air introducing structure from the exterior air introducing mode to the interior air recirculation mode during a period of time from a prescribed point in time until the driving end time to restrict windshield fogging while in the interior air recirculation mode.
