Title: Air-conditioner device for vehicle
Inventor: ISSHI YOSHINORI
IPC: B60H1/00
Filed: 2001-10-30
Abstract: PROBLEM TO BE SOLVED: To provide an air-conditioner device for a vehicle capable of suppressing a deterioration of the comfortableness resulting from noise, a flush in face, etc., when the vehicle is in the auto F/D mode which does not give the driver a proper sense whether the wind shield is really blurred. SOLUTION: An air-conditioner ECU 10 makes the blowout wind quantity or wind delivery rate of the air conditioning wind to the wind shield smaller than the value given by the manual setting in case the operation takes place in the auto-control. In case the mode to perform blur prevention is set as the F/D mode while the operation takes place in the auto-control, deterioration of the comfortableness due to noise, flush in face, etc., can be suppressed by lessening the air conditioning wind to the wind shield when the driver can not judge whether the wind shield is really blurred. In case the F/D mode is selected by manual setting, the operation with priority given to blur prevention is made by increasing the air conditioning wind to the wind shield more than in the auto-control in compliance with the situation in which the driver, etc., selects the blur prevention as necessary.
