Abstract: A circuitry for an antilock and/or drive slip controlled braking system essentially has circuits (1) for forming wheel-sensor signals, regulating circuits (2) for evaluating and processing the formed sensor signals and for generating brake pressure control signals, monitoring circuits (3) which process the sensor signals independently from the regulating circuits (2), and circuits (8, 8', 9') for exchanging and comparing signals from the regulating circuits (2) with corresponding signals from the monitoring circuits (3). The structure of the monitoring circuits (3) is more simple than that of the regulating circuits (2). The regulation philosophy is reproduced in the monitoring circuits (3). In particular, the regulating phases are determined by reproduction (14) on the basis of the same regulation criteria and parameters said reproduction using the regulating circuits (2).
