Abstract

A method for the computer-aided determination of a control variable using context information from one or more units to be controlled is described. This method involves a controller using simulation to ascertain a piece of simulated context information which is used as a control variable, wherein the simulated context information comprises a first variable which represents a presumed state of the one or more units at a given time. The controller compares a received piece of context information, which comprises a second variable which represents the actual state of the unit to be controlled at a time which is before the given time, with the simulated context information and checks whether the simulated context information matches the context information within prescribed limits. In addition, the controller requests a piece of updated context information from one or more units to be controlled if the simulated context information matches the context information at the given time outside the present limits.
