1. A method for controlling a variable water pump, wherein a variable water pump for circulating a coolant is simultaneously controlled in association with an integrated flow rate control logic which controls a coolant flow based on a driving status of a vehicle, the method comprising steps of:
controlling, by an integrated controller, the variable water pump to circulate the coolant and an integrated flow rate control valve to control the coolant flow using the integrated flow rate control logic; classifying, by an integrated controller, flow rate control modes into a heating mode and a fuel efficiency mode in consideration of operation information of an engine and the driving status of the vehicle; and controlling, by an integrated controller, an operation of the variable water pump based on the operation information of the engine and the driving status of the vehicle in the heating mode or the fuel efficiency mode. |
