SYSTEM FOR CONTROLLING ELECTRIC OIL PUMP OF AUTOMATIC TRANSMISSION AND METHOD THEREOF

摘要

Provided is a control method of an electric oil pump for an automatic transmission which minimizes power loss by driving the electric oil pump when a start intention of a driver is detected after a power source. The method includes the steps of: driving the electric oil pump at′A′RPM, which is a maximum velocity, when the power source is turned on; stopping the driving of the electric oil pump when a set time (t) determined by the temperature of the automatic transmission oil has elapsed; and driving the electric oil pump at′A′RPM for the set time (t), and thereafter, driving the electric oil pump at′B′RPM when a selection of a driving shift stage and release of a brake are detected.
