ELECTRIC POWER STEERING DEVICE

An electric power steering device performs assist control of a steering system by calculating a first current command value, based on at least steering torque and driving a motor, based on the first current command value, The electric power steering device includes: a control rotational displacement calculation unit (101) configured to calculate a control rotational displacement when a steering angle of the steering system is in an angular range from a maximum allowable steering angle for the steering system to a predetermined threshold steering angle, the control rotational displacement being a steering angular displacement of the steering angle with the threshold steering angle as a reference; a control steering angle shifting unit (120) configured to calculate the control rotational displacement corrected by a correction amount based on one of the steering torque and rack axial force and a sign of one of the control rotational displacement and the steering angle as a shift control steering angle; and a feedforward control unit (160) configured to output a second current command value based on the shift control steering angle and steering velocity, wherein the electric power steering device calculates a third current command value by adding the second current command value to the first current command value and performs the assist control, using the third current command value.
