Abstract: PURPOSE: An electric power steering system and a control method are provided to supply convenience improved for driving straight by optimally control a compensation torque on a lateral force applied from a side direction during driving and by reducing steering feeling of a driver in pulling. CONSTITUTION: A steering torque, a steering angle, a steering direction, and a driving speed are set on a map in order to determine a basic compensation torque. The steering torque, the steering angle, the steering direction, the driving speed, a reentering angle are analyzed in order to determined straight driving. When a vehicle drives straight, the steering angle and the reentering angle are determined so that a lateral force applied from a side direction of the vehicle is determined. A deformation prevention compensation torque is determined according to the lateral force. The deformation prevention compensation torque is applied to the basic compensation torque so that a steering force is supplied to the steering torque for driving straight. When temporary straight driving separation is according to lane change or obstacle avoidance, the steering force is supplied by applying the compensation torque to which the deformation prevention compensation torque is applied.
