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