1. A predictive traction control method, comprising:
determining, by a predictive control unit, whether predictive traction control is being performed;
detecting, by a road surface conditions information providing unit, an upstream road surface condition in a travelling direction of a vehicle driven by a driving motor;
in response to the determination, by the predictive control unit, that the predictive traction control has not been entered;
determining, by the predictive control unit, whether to accelerate the vehicle according to a driver's will when the upstream road surface condition is determined to be slippery;
calculating, by the predictive control unit, target driving motor speed for controlling the driving motor and transmitting the same, when the vehicle is accelerating;
utilizing, by a target driving motor torque calculating unit, the target driving motor speed to calculate a target driving motor torque for controlling the driving motor; and
controlling, by a driving motor control unit, based on the calculated target driving motor torque, a current applied to the driving motor.
