1. A traction control method for a vehicle provided with a torque vectoring apparatus including a torque vectoring motor, the traction control method comprising:
determining, by a first controller and a second controller, whether a current situation of the vehicle is a split-μ situation occurring when the vehicle is driven on a split road surface, based on vehicle driving information collected in the vehicle;
determining and generating, by the second controller, a target speed for control of a slip wheel speed when the first controller and the second controller determine that the current situation is the split-μ situation, and transmitting the target speed from the second controller to the first controller;
generating, by the first controller, a torque command for the torque vectoring motor for control of the slip wheel speed to follow the target speed received from the second controller; and
controlling, by the first controller, operation of the torque vectoring motor in accordance with the generated torque command.
