The present invention in that, in the hybrid vehicle to specifically calculate the clutch input torque of the engine clutch based on the charging torque of the starter generator controlling the release of the engine clutch engine clutch control apparatus and method according to the engine clutch control of a hybrid vehicle unit It relates.
To this end, the engine clutch control apparatus for a hybrid vehicle according to an embodiment of the invention the engine for selectively coupling the engine and the drive motor located between the engine and the drive motor clutch; It is connected to the engine start-up or start-up generator to power the engine; And comprising: a vehicle controller that controls the release or joint of the engine clutch implement the running mode, the vehicle controller the filling check the charge available torque and the engine target prediction torque based on the rotation number generator of the start generator, and can set the target engine torque and the charge torque according to the torque, and to release the target engine torque, the engine friction torque, and generates a clutch input torque by using a charge torque and the clutch input torque is smaller than the reference value when the engine clutch.
