Claim Text:
1. A system for controlling an engine clutch of a hybrid vehicle, comprising: a sensor configured to sense whether the engine clutch is released in a transfer from a hybrid electric vehicle (HEV) mode to an electric vehicle (EV) mode; a first motor torque controller configured to adjust a motor torque in a transfer section to be changed to a level where the acceleration of the vehicle before and after the release of the engine clutch is maintained substantially constant, in response to determining that the engine clutch has been released; and a second motor torque controller configured to adjust the motor torque in the transfer section to the level of a driver request torque in the EV mode, wherein the first motor torque controller is configured to calculate the motor torque in the transfer section at a level where a change in acceleration of an engine clutch rear part is prevented, in consideration that inertia is changed from Inertia of the engine clutch part (J1)+Inertia of the engine clutch rear part (J2) to Inertia of the engine clutch rear part (J2).
