Abstract
The invention relates to a computer system for carrying out safety-critical applications, said computer system comprising a plurality of node computers and a communications system. Sensor data are supplied in parallel to one or more node computers, the node computers calculating an optimized result, preferably using an optimization algorithm, in order to solve a given problem, and transmitting said optimized result, preferably for checking the safety, to a node computer which is designed as an SCFCU, said SCFCU being directly connected to the actuator controller, and the SCFCU furthermore calculating from the sensor data a simple result, which preferably meets all safety requirements, and an envelope of the simple result, and the SCFCU checking whether the resulting values, particularly those relevant to safety, of the optimized result lie within the envelope of the simple result, and, if this is the case, directly forwarding the optimized result to the actuator controller, and, if this is not the case, forwarding the simple result calculated by the SCFCU directly to the actuator control.
