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.
