Description

Apparatus and method for controlling air conditioner

The present invention relates to an air conditioner control device and method, and more particularly to an air conditioner control device and method for controlling the blower and the temporal door according to the set temperature set by the driver.

Recently, all systems of automobiles are becoming more automated and electronic. This trend can be said to have a purpose to promote safer operation by creating a convenient and comfortable driving environment. Accordingly, automobile air conditioners are gradually developing from manual to high-end passenger cars (FATC: Full Automatic Temperature Controller), and it is expected that the automatic air conditioners will be expanded to all passenger cars in the near future.
