ABSTRACT:
The braking force to the driven wheels is subjected to feedback control so as to allow the actual slip value of the driven wheels to agree with a predetermined target value for controlling the brake. The control amount for the feedback control is determined by differentiation control. The feedback control amount contains a first control amount corresponding to a predetermined basic travelling state and a second control amount corresponding to a particular travelling state. In ordinary travelling state, the braking force is controlled by the first control amount, and the braking force is controlled by the second control amount when the automotive vehicle is travelling in such a particular state. When the the vehicle is travelling on a bad road, the second control amount is set so as to loosen the braking force, as compared with the first control amount. Alternatively, when the vehicle is cornering, the second control amount is set as to tighten the braking force as compared with the first control amount.
