Abstract
The present invention relates to a cooling system for cooling a driving motor of a hybrid vehicle and a method for controlling the same which supplies suitable cooling flow according to temperature and temperature change rate of the driving motor. An exemplary embodiment may include: an electric oil pump to generate hydraulic pressure for cooling the driving motor; a switching valve to selectively transmit the hydraulic pressure to the driving motor; a solenoid valve to selectively supply control pressure to the switching valve so as to switch hydraulic lines in the switching valve; and a control portion controlling operations of the electric oil pump and the switching valve, wherein the control portion operates the electric oil pump by various operation amounts or stops the electric oil pump according to temperature of the driving motor and temperature change rate of the driving motor, and turns on or off the solenoid valve.
