Abstract
A system for correcting a wheel speed data produced by a wheel speed sensor, employs a filter for removing noise contained in the output of the wheel speed sensor. The filter limits variation rate of the wheel speed data so as to avoid occurrence of extraordinary variation of wheel speed as influenced by error factors, such as destruction of the wheel speed sensor or noise superimposed on the output of the wheel speed sensor.
