Abstract

A method is provided by which a complex electronic system for controlling a safety-critical technical process, for example driving an autonomous vehicle, can be implemented. A distinction is made between simple and complex software, wherein the simple software is executed on error-tolerant hardware and wherein a plurality of diverse versions of the complex software are implemented simultaneously on independent fault containment units (FCU). A consolidated environmental model is developed from a number of different environmental models and represents the basis for trajectory planning.
