Abstract

A brake system with anti-lock and/or traction slip control, wherein quantities (.DELTA.t.sub.EV, .DELTA.t.sub.AV) determining the pressure in the wheel brakes (10, 11) are measured and assessed. A wheel pressure pattern (p(t)) is formed from these quantities by integration which, by approximation, represents the pressure variation in the wheel brakes (10, 11). The output signal of the integrator (20) is fed back to the control logic (16) and assessed for slip control and/or braking pressure control. For the integration, taken into account are the braking-pressure-increase and braking-pressure-decrease characteristic curves (P.sub.A, P.sub.E) and the initial conditions (21) which represent the initial pressure upon commencement of the control.
