<p>Disclosed is an air conditioner for a vehicle, capable of performing an automatic fan control on a blower (5) even when a failure or short circuit occurs in sensors. This air conditioner for a vehicle has: a blower (5) provided in an air conditioning duct; an engine speed sensor for detecting a rotational speed of an engine mounted on the vehicle; a vehicle speed sensor for detecting a speed of the vehicle; and a controller for receiving output signals from the sensors and performing an automatic fan control on the blower. The controller determines whether the engine speed is equal or higher than a predetermined value and determines whether the vehicle speed is equal to or higher than a predetermined value, in each of the case where the engine speed is equal to or higher than the predetermined value and the vehicle speed is equal to or higher than the predetermined value, the case where the engine speed is equal to or higher than the predetermined value and the vehicle speed is lower than the predetermined value, and the case where the engine speed is lower than the predetermined value and the vehicle speed is equal to or higher than the predetermined value, the automatic fan control on the blower is performed. In the case where the engine speed is lower than the predetermined value and the vehicle speed is lower than the predetermined value, the automatic fan control on the blower is stopped. <IMAGE></p> |
