Abstract
In a CPU () for calculating a control amount of an electric power steering control apparatus including a motor for assisting a steering force of a steering wheel generated by a driver of a vehicle, a filter section () subjects a value of a motor rotation speed calculating section () for calculating an rotation speed of a motor () to filter processing, to thereby output the resultant value to a target d-axis current value setting section (). With this configuration, in a high-torque and high-motor-rotation speed region, responsiveness of a target d-axis current value with respect to the motor rotation speed is decreased, to thereby suppress vibrations and noise when the steering wheel is operated.
