In an engine torque convergence vibration reduction control method applied to a vehicle (1) of the present invention, an engine torque is checked immediately before a starting off based on an engine load when starting an engine (1-1), a fuel injection amount for the engine torque immediately before the start off is calculated, and the engine torque gradually converges to zero at the starting off by an engine torque convergence control for controlling the fuel injection amount until the engine stops, so that vehicle vibrations associated with engine vibrations are greatly reduced due to amplitude reduction and minimization of vibration intensity, and especially, an engine torque control is realized based on the fuel injection amount, thereby improving the vehicle vibrations without constraints of Jake brake or throttle valve.
