Abstract

A circuit configuration for a brake system with anti-lock control and traction slip control comprising, wheel sensors for generating electric signals representing the wheel rotational behavior and circuits for the cornering identification is provided such that lateral reference speeds (13, 14) are formed by virtue of selection circuits (8, 9) which select leading wheel speed according to specific criteria, and by virtue of a filter means (10, 11) whose time constants (12) are variable. A difference signal (DVS) is formed of the lateral references speeds (SRG.sub.L, SRG.sub.R), the magnitude of which is variable by inverse feedback. This difference signal (DVS) serves to actuate an adaptation circuit (18) as a function of the vehicle reference speed (V.sub.REF). The adaptation circuit influences on the control thresholds of the anti-lock control and traction slip control to adapt the control to the particularities of cornering.
