The purpose of the present invention is to provide an air conditioning device for vehicles, which is constructed to compensate for a change in a discharged air temperature inside a vehicle without any separate sensors for detecting the discharged air temperature when the discharged air temperature is changed by a change in the driving environment of the vehicle, and thus the number of sensors may be reduced, thereby achieving an effect of cost reduction. In order to achieve this purpose, the air conditioning device for vehicles comprises a compressor, a heater core, a blower, a temp. door, an intake door, and a control part for automatically controlling each door mode such that a target discharge temperature is calculated by processing an external temperature, an internal temperature, and an amount of solar radiation, which are inputted by each sensor, and a temperature set by a user, which is inputted by a temperature control switch; and a discharged air temperature inside a vehicle is controlled in accordance with a calculated target discharge temperature. In this regard, the air conditioning device for vehicles further comprises a unit for detecting a discharged air temperature change inducing factor, which detects induction factors that change a discharged air temperature inside a vehicle. In addition, the control part is characterized in that when the discharged air temperature is changed, an opening position correction value is calculated by processing the induction factors that change a discharged air temperature inside a vehicle, which are inputted by the unit for detecting a discharged air temperature change inducing factor, and the target discharge temperature with a previously built-in arithmetic expression, and an opening position of the temp. door is corrected based on a calculated opening position correction value of the temp. door. |
