ABSTRACT:
An anti-skid control system includes a wheel speed calculation in which newly derived wheel speed is compared with a wheel speed derived at an immediately preceding calculation. When the newly derived instant wheel speed is different from the previously derived old wheel speed beyond a predetermined value which is variable in dependent upon variation of the wheel speed derived at the immediately preceding calculation. A back-up signal is derived and output as a replacement of wheel speed data. The back-up signal may have a value substantially corresponding to a wheel speed data avoiding error component in the instant wheel speed.
