Abstract
The present application discloses a control apparatus for electric power steering, including: a gain determination portion configured to determine a first assist gain in correspondence to a steering torque acting on a steering shaft when a driver rotates a steering wheel; and a gain adjuster which adjusts the first assist gain in response to a change in a rotation direction of the steering wheel to generate a second assist gain. The gain adjuster generates the second assist gain so as to reduce a difference between a first torque, which is required of the driver rotating the steering wheel to a predetermined rotation position, and a second torque, which is required of the driver holding the steering wheel at the rotation position.
