A hydraulic pressure instruction-learning apparatus of a hybrid vehicle includes a power source including an engine and a motor. The engine clutch is disposed between the engine and the motor. The vehicle controller is configured to output a hydraulic pressure instruction to control engagement/disengagement of the engine clutch. The vehicle controller compares output performance of the engine clutch with predetermined dynamic target performance in a launch control, extracts a performance error function if a difference therebetween exceeds a predetermined allowable error range, and corrects the output performance of the engine clutch, such that the output performance falls within the predetermined allowable error range and is stored as a learned value.
