Abstract: A method to generate configuration data to enable and/or to enhance real-time communication in a cyber-physical system or in a cyber-physical system of systems. The system includes components connected to each other by a communication infrastructure. The components each execute at least one application, which applications exchange information with at least one application being executed on another component. The components are configured to send and/or receive said information according to configuration data: The first configuration data for two or more of the components, on each of which at least one application is executed, is generated by execution of a publish-subscribe protocol, which is executed by two or more of the components, for which the first configuration data are provided.

Abstract: A fault-tolerant computer system (FTCS) for generating safe trajectories for a vehicle. The FTCS includes: a sensor part (SENSE), a primary part (PRIM), a secondary part (SEC), a tertiary part (TER), and a decide part (DECIDE). The PRIM and TER are configured to produce trajectories by interpreting information of the real world as perceived by the SENSE. The SEC is configured to produce a safe space estimate (FSE) by interpreting information of the real world as perceived by SENSE. The DECIDE and/or SEC are configured to execute correctness checks that take trajectories and FSE as inputs, and qualify a trajectory (TRJ) as safe when said TRJ is inside the FSE, and qualify a trajectory (UTRJ) as unsafe when said UTRJ is not inside the FSE.

Abstract: A method for operating a controlled object that is embedded in a changing environment. The controlled object and its environment are periodically observed using sensors. Independent data flow paths (“DFP”) are executed based on the data recorded through the observation of the controlled object and its environment. A first DFP determines a model of the controlled object and the environment of the controlled object and carries out a trajectory planning in order to create possible trajectories that, under the given environmental conditions, correspond to a specified task assignment. A second DFP determines a model of the controlled object and of the environment of the controlled object and determines a safe space-time domain (“SRZD”) in which all safe trajectories must be located. The results of the first and the second DFP are transmitted to a deciding instance to verify whether at least one of the trajectories is safe.

Abstract: A method for transmitting control commands in a computer system, which includes components at least in the form of nodes, actuators and communication systems, wherein the control commands are communicated over the communication systems from the nodes to the actuators, and wherein one or more of the components may fail to operate according their specification. For consistently accepting control commands at the actuators, the nodes and their control commands are assigned priorities, wherein a node and its control commands have the same priority, wherein at least two priorities are used, wherein a high priority node produces high priority control commands and a low priority node produces low priority control commands, and wherein a high priority node is configured to communicate its control commands over at least two communication systems to the actuators and a low priority node is configured to communicate its low priority control commands over at least one communication system to the actuators.

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.
