METHOD FOR CONTROLLING COOLING FAN OF AIR CONDITIONER IN VEHICLE, MAINLY CONCERNED WITH IMPROVING THE VISIBILITY OF DRIVER BY RELIEVING RAPID LOWERING OF BRIGHTNESS OF HEAD LAMP

摘要

Purpose: a kind of method, the fan for controlling the air-conditioning in a vehicle is arranged to improve the visibility of a driver by mitigating the brightness decline of one head lamp of torrent, due to a switching current of a desk fan driving motor. Construction: an ECU (Electronic Control Unit) detects whether that the air-conditioning work from that vehicle driving of a state switchs, and a signal is entered or looks on. If signal is entered, ECU exports the signal that the first relay is used to drive the first motor, so that the first fan is driven. ECU, which opens a compressor and exports, is used to drive a signal of the second relay of a stand-by motor so that the second fan is driven.
