ABSTRACT:
An electric power steering apparatus comprising a broken-line function circuit for outputting a predetermined analog broken-line function signal on the basis of a torque detection signal, a gain circuit for giving a predetermined gain to the broken-line function signal, a polarity inverting circuit for inverting the polarity of the broken-line function signal, a first attenuating means for attenuating the torque detection signal at a predetermined rate, a second attenuating means for attenuating an output signal of said polarity inverting circuit at a predetermined rate, an addition circuit for adding a signal from the first attenuating, a signal from the second attenuating means and an output signal of the gain circuit, and outputting the addition value as a target value of a motor current, and a differential amplifying circuit for calculating a difference between the target value and the motor current detected by a detecting circuit for the purpose of feedback control, wherein a steering force assisting motor is driven on the basis of an output signal from the differential amplifying circuit.
