An electric power steering apparatus provides a steering assist force to the steering system of a vehicle by controlling driving of an assist motor in accordance with a steering force acting on the steering wheel. The electric power steering apparatus includes a yaw rate sensor that obtains a measured yaw rate of the vehicle, a vehicle speed sensor that detects the speed of the vehicle, a steering angle sensor that detects the steering angle of the steering wheel, and a torque estimating apparatus that estimates a self-aligning torque on the basis of the vehicle speed and data having a smaller absolute value among the measured yaw rate and the steering-angle standard yaw rate and that corrects the steering assist force on the basis of the estimated self-aligning torque.
