Abstract
An engine stop control method of a power split-parallel hybrid electric vehicle (HEV) system may include: determining any one driving mode among an EV mode, a power split mode and a parallel mode, corresponding to a driver's request; recognizing and deciding whether the driving mode is a mode required to stop an engine; stopping the engine; and performing kill torque (TQ) control on the revolution speed of the engine through a motor so that the revolution speed of the engine reaches 0 rpm. Accordingly, the revolution speed of the engine can be reduced down to an rpm lower than that of the conventional art, thereby promoting fast mode conversion.
