AIR CONDITIONING CONTROL SYSTEM FOR A VEHICLE USING REAR-SEAT INFRARED SENSOR

摘要

The present invention relates to an air conditioning control system using a rear-seat infrared sensor for a vehicle. The air conditioning system comprises: a rear seat-infrared (IR) sensor (10); and a control part (20). The rear seat-IR sensor (10) is positioned on a loop part of the vehicle. The control part (20) controls an air conditioning device (100) based on information detected by the rear seat-IR sensor (10) and information detected by each of an indoor temperature sensor (S1), an outdoor sensor (S2), and a pyranometer sensor (S3). The rear seat-IR sensor (10) detects the surface temperature of a rear seat or a surface temperature of a rear seat with a seated passenger and the surface temperature of a rear window (RW) of the rear seat. The control part (20) estimates the direction and amount of solar radiation based on the surface temperature detected by the pyranometer sensor (S3) and the rear seat-IR sensor (10) to control the temperature of discharged air of the air conditioning device (100). According to the present invention, the amount of solar radiation is predicted using the information obtained from the pyranometer sensor and the information obtained by the rear seat-IR sensor, thereby controlling the interior temperature of the vehicle for greater passenger comfort.
