Claim:
1. A system for controlling torque of a hybrid vehicle, comprising: an engine; a first motor for controlling engine speed; a second motor compensating engine torque and generating demand torque; and a control portion controlling the engine, the first motor, and the second motor, wherein the control portion calculates torque of the first motor at a transient state by using target torque of the second motor at a steady state, and calculates torque of the second motor at the transient state by using the torque of the first motor at the transient state, wherein target torque at the steady state is target torque of each motor when present driving conditions of the first and second motors and the engine are maintained for a predetermined period of time, and wherein torque at the transient state is torque of each motor calculated to meet the target torque of each motor at the steady state when the driving conditions of the first and second motors and the engine change.
