Abstract
The electric power steering control device includes: a steering wheel; a torque generation unit for generating a generated torque for assisting a torque generated by steering by a driver; a torque detection unit for detecting a torsion generated between the steering wheel side and the torque generation unit side as a detected torque; an assist torque command calculation unit for calculating, based on the detected torque, an assist torque command for assisting the steering by the driver; and a differential rotational speed calculation unit for calculating a difference in a rotational speed generated between the steering wheel side and the torque generation unit side as a differential rotational speed, in which the torque generation unit generates the generated torque based on a compensation torque, which is set depending on the assist torque command and the differential rotational speed.
