Abstract
A controller for a vehicle makes it possible to prevent window glass from fogging and also to reduce fuel consumption in conducting control to temporarily stop an engine when a vehicle stops. The controller for a vehicle includes a vehicle condition detector which detects a condition under which a vehicle is being placed, a fogging determination humidity estimator which estimates a fogging determination humidity, which is a humidity not causing window glass of the vehicle to fog up under the condition detected by the vehicle condition detector, a humidity detector which detects the humidity in the vehicle, and an engine stop duration determiner which determines a longer engine stop duration as the humidity difference increases between the humidity detected by the humidity detector immediately before an engine is stopped and the fogging determination humidity. An engine control unit restarts the engine and also starts up a refrigeration cycle unit and a blower fan when an engine stop duration has elapsed following an engine stop.
