PURPOSE: A method and an apparatus for controlling the torque of a hybrid vehicle equipped with two motors are provided to calculate the optimal torque of each motor at transition state by successively determining the power and the torque of motors. CONSTITUTION: The desired power of a battery is determined based on the speed of a vehicle, required torque, and state of charge. The desired torque of a first motor(30), a second motor(40), and an engine(10), and the desired speed of the engine are calculated at normal state. The desired power of the second motor is calculated at normal state based on the desired torque and the rotary speed of the second motor at normal state. The maximum power of the first motor at transition state is calculated. The maximum torque of the first motor is calculated at transition state. The torque of the second motor at transition state is calculated based on the first motor at transition state and the speed of the motors.
