Abstract: A method for controlling the engine torque of a vehicle of the present invention calculates Δ engine torque changed in an engine (5) using generator power calculated from the load change of a generator (1); converts the Δ engine torque into target engine torque by adding the Δ engine torque to the engine torque; and allows an ECU (3) to control the engine (5) with the target engine torque. The present invention can utilize, as feedback duty, the generation load precisely detected in a point when the change of the generation amount of a generator (load change) is increased and can remarkably improve noise, vibration, and harshness (NVH) and remarkably increase the safety of the engine control by allowing the ECU to control the engine while the target torque required to control the engine is calculated with the precisely detected generation load.
