Abstract
A vehicular anti-lock control method including the steps of comparing a wheel speed with a reference value which is based on a vehicle speed estimated from the wheel speed, judging the locking tendency of a wheel from the result of such comparison and reducing a brake pressure to be applied to the wheel which is on the way to locking, a first vehicle speed is estimated based on the speed of a wheel including a driving wheel and a second vehicle speed is estimated based on the speed of a follower wheel, the driving wheel being judged to be in a racing state when the first vehicle speed is larger than the second vehicle speed above a predetermined value. When the driving wheel is racing, the first vehicle speed is held constant and as far as such racing is present the constant vehicle speed is used to determine the reference value for comparison with the wheel speed.
