Abstract: The present invention relates to a circuit arrangement to monitor a regulated output voltage in an automotive vehicle, wherein the regulated output voltage is monitored as to whether defined threshold values have been exceeded and/or have fallen short of, wherein the circuit element for regulating the output voltage and the circuit element to monitor whether threshold values have been exceeded or have fallen short of are integrated in one chip, wherein the adjustment of the output voltage is effected by way of a first reference voltage, and wherein monitoring of the threshold values as to whether they have been exceeded or have fallen short of is conducted by way of a second reference voltage.

Abstract: To control a brake slip control apparatus, the rotational behavior of the wheels or of the axles is sensed with the aid of sensors, and the sensor signals for the generation of valve control signals, by which the braking pressure at the wheels is controlled dependent upon the wheel rotational behavior, will be processed electronically. On the basis of these sensor signals, valve control signals will be produced in at least two independently acting, synchronously driven logical circuit units, which may be integrated circuit configurations or complete "microcontrollers" or single-chip-microcomputers, and the signals' waveforms of each of the two circuit units can be compared and checked for agreement externally and internally at corresponding locations within the two circuit units. Upon the occurrence of variations in the external and/or the internal signals or in the signals' waveform, there will be caused, initiated or prepared a complete or partial disconnection of the brake slip control.
