A control method of a hybrid vehicle is provided to prevent or reduce shock in a power train of the hybrid vehicle in starting an engine with changing an electric motor vehicle mode into a hybrid mode and changing the hybrid mode into the electric motor vehicle mode by cutting off power of the engine. A hybrid vehicle comprises a carrier connected to an engine, a sun gear connected to a first motor, a ring gear connected to a second motor and a differential, and a controller controlling the first and second motors and the engine. For a hybrid vehicle control method, the second motor outputs variable torque in changing an electric motor vehicle mode and a hybrid mode. The variable torque is obtained by subtracting a value output by applying the direction characteristic opposite to the torque direction of the first motor, to small one between an absolute value of the torque of the ring gear for the actual torque of the engine and an absolute value of the torque of the ring gear for command torque of the first motor commanded by the controller, from the torque of the ring gear for reference torque of the engine normally operated in a hybrid mode.
