摘要： 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.
