Traction control method for vehicle

A traction control method for a vehicle, the method comprising:

• determining, by a controller, entry of traction control based on real-time vehicle driving information in the vehicle provided with a torque vectoring motor;
• estimating, by the controller, a wheel speed of the vehicle based on a rotation speed of a driving system of the vehicle or a vehicle acceleration detected by an acceleration sensor in a state in which the traction control is entered and determining a slipping wheel target speed based on the estimated wheel speed;
• determining, by the controller, a wheel speed error based on the determined slipping wheel target speed and a slipping wheel actual speed detected by a wheel speed sensor and determining motor-based wheel speed errors based on the wheel speed error, and
• determining, by the controller, motor traction control torque to control each of a driving motor configured to drive the vehicle and the torque vectoring motor based on the determined motor-based wheel speed errors and a requested torque of a driver.
