Abstract
The present invention relates to a method and apparatus for controlling electric power steering. In particular, the present invention provides a power steering control method that includes: a breakdown detection step of detecting whether a torque sensor has broken down; an information reception step of receiving steering angle information and vehicle speed information in the case in which the torque sensor has broken down; a compensation target value calculation step of calculating a self-aligning torque, and a damping force, an inertial force, and a frictional force of an electric power steering apparatus by using one or more of the steering angle information and the vehicle speed information; and a current control step of calculating a steering assist force based on the compensation target value and controlling the supply of a motor control current that corresponds to the steering assist force, and an apparatus for the same.
