    • A microprocessor configuration for a control system of a vehicle comprises a plurality of microprocessor systems (4,5,6) which are interconnected by bus systems (1,2,3) and include an anti-lock and/or traction slip control system and further control systems, which require complex computing operations, as well as an input signal conditioning system (SC). For the purpose of error detection one part of the data processing is performed “symmetrically” redundantly in a plurality of microprocessor systems and another part of the data processing is additionally performed (“asymmetrically” redundantly) in accordance with simplified algorithms. Two like master microprocessor systems (5,6) are provided which serve the symmetrically redundant data processing. The input signal conditioning and the processing in accordance with simplified algorithms are installed in a third microprocessor system (4). The output and/or intermediate results are compared for redundancy; moreover, the data processing performed in these microprocessor systems is each time compared and checked for plausibility with the results of the simplified data processing.

    • A circuit arrangement for monitoring leakage currents of a circuit which includes a plurality of valve coils connected in parallel to a supply line and adapted to be connected to ground by way of individual switches, and wherein the supply line is connected by way of a main switch to the positive pole of the supply voltage source and, further, to a testing current source used as a test signal source, is designed such that prior to each closing of the main switch, with the individual switches still open, the testing current source is connected to the supply voltage source and thereby activated. The result is an increase of the voltage potential on the supply line. A comparator establishes the difference between the potentials on the supply line and the supply voltage. If the difference exceeds a threshold value, this indicates leakage current.

    • To evaluate the output signal of an active sensor which is configured as a binary current signal, a circuit arrangement is disclosed by which a proportional current is produced from the sensor current by way of a current mirror circuit. The current produced by a current mirroring operation is drawn from a stabilized voltage source by way of an ohmic resistance, and a binary voltage signal corresponding to the sensor output signal is generated thereby. The voltage signal is sent to a flipflop which compares the voltage signal with a reference value that is composed of a reference voltage and a hysteresis voltage. The change-over threshold of the flipflop is varied or adapted as a function of the actual sensor current, leakage currents, etc.
