A motor-driven power steering control apparatus assuring consistently comfortable steering operation of a motor vehicle includes a steering state detecting ( 10 ), a motor drive command value arithmetic device ( 20 ), a trouble detector ( 40 ), a motor drive command value corrector ( 51, 52 ) for decrementing a motor drive command value outputted from the motor drive command value corrector ( 51 ) from a predetermined initial value as a function of time lapse when a trouble detection signal is outputted from the trouble detector ( 40 ), and an element ( 30 ) for driving an assist motor in conformance with the output of the motor drive command value corrector ( 51, 52 ). The motor drive command value corrector ( 51, 52 ) includes a low-pass filter ( 515 ) for smoothing the motor drive command value. A value acquired through the low-pass filter ( 515 ) is employed as the predetermined initial value.
