Vehicle air conditioner with louver operation control

An air conditioner for a vehicle having a passenger compartment, comprising:

• an air conditioning unit having a plurality of air outlets for blowing conditioned air toward plural air-conditioning zones in the passenger compartment, the air conditioning unit being set to respectively independently adjust air temperature to be blown toward at least two of the plural air-conditioning zones;
• a plurality of air-blowing state changing units for changing a blowing range of the conditioned air blown from the air outlets;
• and
• an air-blowing state control unit for controlling an operation state of the air-blowing state changing units;
• and
• an actuator for driving and operating the air-blowing state changing units, the actuator including plural driving units having number smaller than number of the air-blowing state changing units, wherein:
• the air-blowing state control unit controls the plural driving units to control the operation state of the air-blowing state changing units;
• and
• the operation state is one of a swing range, a swing stop time, a slow operation time for which the air-blowing state changing units are operated with an operation speed lower than a predetermined speed, and a slow operation range in which the air-blowing state changing units are operated with an operation speed lower than the predetermined speed.

• an actuator for driving and operating the air-blowing state changing units, the actuator including plural driving units having number smaller than number of the air-blowing state changing units, wherein:
• the air-blowing state control unit controls the plural driving units to control swing operations of the air-blowing state changing units so that air is blown from at least two of the air outlets to be approximately symmetrical relative to a center line.

• a plurality of air-blowing state changing units for changing a blowing range of the conditioned air blown from the air outlets;
• and
• an air-blowing state control unit for controlling an operation state of the air-blowing state changing units, wherein the air-blowing state control unit controls the air-blowing state changing units in such a manner that one of the air-blowing state changing units is operated with first operation patterns each having a first periodicity, the other one of the air-blowing state changing units is operated with second operation patterns each having a second periodicity, and a ratio of the first periodicity to the second periodicity is approximately an integer number.
