Abstract
Noise may be prevented from being generated while providing smooth shift operability by preventing the overshoot phenomenon in which rpm of the electric oil pump is unexpectedly increased as the load decreases at the time when shifting ends in controlling the rpm of the electric oil pump to increase in order to increase the line pressure of the transmission as the shifting operation from step N to step D is performed in the hybrid vehicle having the electric oil pump.
