Universal controlling method and system for flow rate of cooling water and active air flap

Abstract

Disclosed are a universal controlling method and a system for a flow rate of cooling water and an active air flap. The universal controlling method for a flow rate of cooling water and an active air flap includes: adjusting, by a controller, a temperature of the cooling water based on a predetermined flow rate mode; and selectively opening, by the controller, the active air flap based on the predetermined flow rate mode.

What is claimed is: 
     
         1 . A universal controlling method for a flow rate of cooling water and an active air flap, comprising:
 adjusting, by a controller, a temperature of the cooling water based on a predetermined flow rate mode; and   selectively opening, by the controller, the active air flap based on the predetermined flow rate mode.   
     
     
         2 . The universal controlling method of  claim 1 , wherein in the cooling water temperature adjustment, the active air flap is closed while the temperature of the cooling water is increased. 
     
     
         3 . The universal controlling method of  claim 1 , wherein in the cooling water temperature adjustment, the active air flap is opened while the temperature of the cooling water is reduced. 
     
     
         4 . The universal controlling method of  claim 2 , wherein during an initial start of an engine, a flow of the cooling water is stopped and the active air flap is closed. 
     
     
         5 . The universal controlling method of  claim 2 , wherein during a warm-up time of an engine, a required amount of the cooling water is supplied to an oil warmer or a heater and the active air flap is closed. 
     
     
         6 . The universal controlling method of  claim 3 , wherein when the temperature of the cooling water is a predetermined reference value or greater, an amount of cooling water to be moved to a radiator is maximally increased, and the active air flap is opened. 
     
     
         7 . A universal controlling system for a flow rate of cooling water and an active air flap, comprising:
 a flow rate controller configured to determining whether to increase a temperature of the cooling water; and   a flap controller configured to open or close the active air flap such that a process of cooling or heating the cooling water is performed based on the determination of the flow rate controller.   
     
     
         8 . The universal controlling system of  claim 7 , wherein the flow rate controller is configured to transmit a signal for closing the active air flap to the flap controller when it is determined to be a mode of raising the temperature of the cooling water. 
     
     
         9 . The universal controlling system of  claim 7 , wherein the flow rate controller is configured to transmit a signal for opening the active air flap to the flap controller when it is determined to be a mode of reducing the temperature of the cooling water. 
     
     
         10 . The universal controlling system of  claim 8 , wherein the flow rate controller is configured to stop a flow of the cooling water and transmits a signal for closing the active air flap to the flap controller during an initial start of an engine. 
     
     
         11 . The universal controlling system of  claim 8 , wherein the flow rate controller is configured to supply a required amount of the cooling water to an oil warmer or a heater and transmit a signal for closing the active air flap to the flap controller during a warm-up time of an engine. 
     
     
         12 . The universal controlling system of  claim 9 , wherein the flow rate controller is configured to maximally increase an amount of cooling water to be moved to a radiator and transmit a signal for opening the active air flap to the flap controller when the temperature of the cooling water is a predetermined reference value or greater.
