Abstract

The present invention relates to a control apparatus for a vehicle air conditioner and a control method thereof, and in particular, a pollution detection sensor unit 10 for detecting an air pollution state inside and outside the vehicle; A comparison determination unit 20 connected to the contamination detection sensor unit 10 and determining the degree of air pollution inside and outside the vehicle due to comparative determination of a signal applied from the pollution detection sensor unit 10; An actuator controller 30 connected to the comparison determination unit 20 and controlling the operation of the internal and external air actuators according to a signal of the degree of air pollution inside and outside the vehicle applied by the comparison determination unit 20. Is the automatic control device of the vehicle interior and exterior, characterized in that the configuration and the operation of the vehicle interior and exterior actuators in the automatic mode? An operation mode edition step 110 for determining whether the operation mode is manual; As a result of performing the operation mode determination step 110, it is determined that the operation mode of the internal and external air actuators is set to the automatic mode, and through the pollution detection unit 10 and the comparison determination unit 20, An air pollution state determination step 120 for detecting a pollution state of the internal air and determining which air is fresh port air; As a result of performing the air pollution determination step 120, when the outside air is more polluted than the inside air, the bet actuator is operated, otherwise the actuator operation step 130 is operated to operate the outside air actuator. It is a control method of the automotive internal and external air control device characterized in that.
