Abstract
In an anti-lock braking apparatus, by detecting brake torque at a wheel and controlling the braking force of a wheel brake unit, a locked state of the wheel can be quickly detected to thus enable braking control with fast response characteristics. Also, based on direction of a variation of the brake torque on the wheel, the road friction coefficient is predicted to perform feedback control for the braking force and to adjust the brake torque to a target brake torque, whereby the braking performance can be optimized.
