1. A method for the integration of calculations having a variable running time into a distributed, time-controlled, real-time computer architecture, which real-time computer architecture consists of a plurality of computer nodes, wherein a global time having known precision is available to the computer nodes, wherein at least a portion of the computer nodes is equipped with sensor systems, in particular different sensor systems for observing the environment, and wherein the computer nodes exchange messages via a communication system, the method comprising:

  • collecting, by the computer nodes, at the start of each cyclical frame Fi having the duration d, raw input data by means of a sensor system, wherein the start times of frame Fi are deduced from the progress of the global time; and

    pre-processing the raw input data by means of algorithms, the running times of which depend upon the input data, and wherein the value of the ageing index AI=0 is assigned to a pre-processing result which is produced within the frame Fi at the start of which the input data were collected, and wherein the value of the ageing index AI=1 is assigned to a pre-processing result which is produced within the frame following the frame in which the input data were collected, and wherein the value AI=n is assigned to a pre-processing result which is produced in the n-th frame after the data acquisition, and wherein the ageing indices of the pre-processing results are taken into consideration in the computer nodes which carry out the fusion of the pre-processing results of the sensor systems.
