Abstract
A first vehicle body speed is calculated based on a wheel rotational speed detected in a speed sensor for an object wheel. The largest value of speeds based on the wheel rotational speeds detected in speed sensors for four wheels is corrected by a correction value based on an inner and outer wheel speed difference during the turning of a vehicle so as to calculate a second vehicle body speed for every object wheel. A higher one of the first and second vehicle body speeds is selected as an estimated vehicle body speed for use in the anti-lock control for the object wheel. This enables a substantially accurate estimation of an estimated vehicle body speed during the turning of the vehicle.
