Circuit arrangement for electronic regulating system e.g. ABS or ASR for motor vehicles

摘要

A methodical function of the switching network, the current supply, of the connected sensors, of the users and other components are monitored as well as the prodn. and evaluation of monitoring and/or test signals. The occurrence of faults is also signalled. A comparator (7) is provided, which continuously compares the supply voltage (UB) of the electronic regulating system with a reference voltage URef). With the occurrence of a fall in voltage or an over voltage, an interrupt signal (Xtint) is produced, the evaluation of the monitoring signals and fault signalling are prevented for a short time or for a specified time interval, until a repeated occurrence of the fault signal, or until a specified number of repetitions of the fault signal has occurred.
