1. A microprocessor configuration for a control system of a vehicle comprising a plurality of microprocessor systems which are interconnected by bus systems and include at least one member of the group consisting of an anti-lock control system and a traction slip control system, and at least one additional control system, which requires complex computing operations, as well as an input signal conditioning system, wherein, for the purpose of error detection, the configuration being capable of performing one part of the data processing redundantly in a plurality of microprocessor systems in symmetrical redundancy and, additionally, one part of the data processing in accordance with simplified algorithms in asymmetrical redundancy, wherein the microprocessor configuration includes two like master microprocessor systems which are assigned to the redundant data processing;

  • wherein a third microprocessor is adapted to perform the input signal conditioning and the processing in accordance with the simplified algorithms; and

    wherein the configuration is capable of comparing results of the data processing amongst each other for concurrence and of comparing and checking these results, for plausibility with the respective results of the simplified data processing.
