Abstract
A device for detecting a wheel speed includes a comparator that converts a sine-wave output signal Sof a wheel speed sensor into a binary wheel speed signal S. Here, the threshold value Vof the comparator is continuously increased in response to a period in which the sine-wave output signal Sis greater than the threshold value V, and is continuously decreased in response to a period in which the sine-wave output signal Sis smaller than the threshold value V.
