摘要： An electric power steering apparatus includes a high-frequency compensation unit that outputs a high-frequency compensation signal obtained by filtering the high-frequency components of an assist torque command signal and multiplying the filtered high-frequency components by a gain; a corrected steering torque signal obtained by negatively or positively feeding back the high-frequency compensation signal to a steering torque signal is inputted to an assist torque command calculation unit; the assist torque command calculation unit outputs the assist torque command signal in accordance with the corrected steering torque signal.

摘要： There is provided an electric power steering device, including: a reverse steering detection unit configured to determine start of reverse steering when a magnitude of a rotational speed of a motor is equal to or smaller than a set speed, a rotational acceleration of the motor is in a direction of causing the rotational speed of the motor to become 0, and a magnitude of the rotational acceleration of the motor is equal to or larger than a set acceleration; and a current command control unit configured to output a current command for the motor based on the steering torque or the rotational speed of the motor, in which the current command control unit is configured to increase a transfer gain from input to output by the current command control unit when the reverse steering detection unit determines start of the reverse steering.
