Abstract: A vehicle air conditioner has an air conditioning unit and an air conditioning control unit. The air conditioning unit has a FACE blowout port, a DEF blowout port, an upper blowout port. The air conditioning control unit estimates an outside windshield temperature and determines an outside dew point temperature. The control unit also controls the upper blowout port to stop blowing or not based on the estimated outside windshield temperature and the outside dew point temperature in a face mode to prevent the windshield from fogging.

Abstract: A control device is provided in a vehicle to control an air conditioning apparatus and thereby to control ventilation and air conditioning of a passenger room of the vehicle. A mobile device communicates with the control device in a parked state of the vehicle to selectively control a first device, which performs ventilation of the passenger room, and a second device, which performs air conditioning of the passenger room, of the air conditioning apparatus in such a manner that at least one of the first device and the second device is selectively operated upon reception of a corresponding operational instruction from the operating device.

Abstract: A ventilation and deodorization system includes a door lock switching unit for performing a locking and an unlocking of a vehicle door, an air conditioner which introduces outside air of a passenger compartment of the vehicle and blows the introduced outside air into the passenger compartment in a ventilation operation, and a control device for controlling its operation. When a door unlocking request signal is received as a remote operation signal by a receiving unit, the door lock switching unit performs the unlocking of the vehicle door, and the air conditioner performs the ventilation operation. Alternatively, an air cleaning operation is performed instead of the ventilation operation, while inside air of the passenger compartment is cleaned and circulated by an air cleaning device. Thus, the ventilation operation or the air cleaning operation can be performed while a battery consumption amount can be reduced.

Abstract: An air conditioner for a vehicle is provided with an air conditioning unit for blowing conditioned air to a passenger compartment of the vehicle, multiple seat air conditioning units for respectively controlling temperatures of seats of the vehicle, and a control unit for controlling the air conditioning unit and the seat air conditioning units. The larger the difference between a target blowing-out temperature of the air conditioning unit and a compartment setting temperature of the passenger compartment, the larger the degree of influence of the target blowing-out temperature on a seat target blowing-out temperature in the calculation of the seat target blowing-out temperature, based on which the seat air conditioning unit is controlled.

Abstract: A control unit for an air conditioning system for a motor vehicle calculates a target blowing air temperature based on a temperature of a passenger's dressing detected by a contact-less temperature sensor. An air conditioning operation is performed based on the calculated target blowing air temperature. In particular, when calculating the target temperature in the summer or in the winter season, a change of the detected temperature of the passenger's dressing is used, so that the change of detected temperature is reflected in the target temperature with a time delay.

Abstract: When it is assumed that a vehicle is stopped or parked after its engine was stopped and a predetermined period of time has passed, a cold wind side air mixing door, hot wind side air mixing door, cold wind door and rear cold wind side air mixing door are totally closed and a blower is operated for a predetermined period of time. Accordingly, while a cooler is being dried, drying air containing much offensive smell components, which has passed through the cooler, is discharged outside the vehicle. Therefore, it is unnecessary to provide an exclusively used air passage and an opening and closing door for opening and closing the air passage used for composing an air blowing passage to dry the cooler. By utilizing the existing equipment, air used for drying, which has passed through the cooler, containing much offensive smell components can be discharged outside the vehicle.

Abstract: In an initial time of a warming-up control of a vehicle air conditioner, a control unit controls a mode switching member to set a foot mode, a first linear bi-level mode, a fixed bi-level mode, a second linear bi-level mode and the foot mode. In the first and second linear bi-level modes, a face-foot air blowing ratio between air blown from a face opening and air blown from a foot opening is gradually changed as the time passes. Therefore, the face-foot air blowing ratio can be smoothly changed in a mode switching between the foot mode and the fixed bi-level mode. Accordingly, when the mode switching is performed in the warming-up control in the winter, the face-foot air blowing ratio is prevented from being suddenly changed.
