PURPOSE: To enhance the controllability by forming a wheel factor used for anti-lock control by detecting a wheel speed by each calculating processing after a preceding or prescribed preceding cycle, and forming it by learning processing so as to be accompanied by a change evaluated for regulating of the wheel factor. CONSTITUTION: A wheel speed V(n) of four wheels of an automobiles is selectively inputted to a selecting circuit 1, where a basic speed VBas(n) is generated. The wheel speed V(n) is imparted to a multiplication stage 3, and multiplied by a wheel factor K(n-1) read from a memory 5, the difference DV(n) between the product and the basic speed VBas(-n) is determined in a difference forming part 2, and the difference DV(n) is outputted to a computer 4. In the computer 4, an actual wheel factor K(n) is calculated on the basis of the difference signal. DV(n), the wheel factor K(n-1), and the actual wheel speed V(n). |
