APPARATUS AND METHOD FOR CONTROLLING COOLING FAN OF VEHICLE

摘要

An apparatus and method for controlling a cooling fan of a vehicle are provided. The apparatus includes an information detector that is configured to detect information for operating the cooling fan and a blower assembly including a motor driving the cooling fan and a resistor adjusting a speed of the motor. A relay unit is configured to selectively supply power to the blower assembly. A connecting unit includes a high speed connector that is directly connected to the motor, a low speed connector that is connected to the motor via the resistor, and a ground connector that connects the motor to a ground. Additionally, a controller is configured to operate the relay unit based on the information detected by the information detector.

1. An apparatus for controlling a cooling fan of a vehicle, comprising:
an information detector configured to detect information for operating the cooling fan; a blower assembly including a motor configured to drive the cooling fan and a resistor configured to adjust a speed of the motor; a relay unit configured to selectively supply power to the blower assembly; a connecting unit including a high speed connector directly connected to the motor, a low speed connector connected to the motor via the resistor, and a ground connector connecting the motor to a ground; a controller configured to operate the relay unit based on the information detected by the information detector, wherein the controller is configured to turn the relay unit on or off based on a state of an air conditioner switch, an air conditioner pressure, and a coolant temperature when an external air temperature is less than a reference temperature.
