Patent ID: 8819250

Claim:
A method for computer-assisted determination of a control variable using context information from a unit to be controlled, comprising: determining simulated context information at a controller using a simulation, the simulated context information including a first variable which represents an assumed state of the unit to be controlled at a given point in time; using the simulated context information as a control variable; receiving actual context information including a second variable, which represents an actual state of the unit to be controlled at a point in time which is before the given point in time; comparing, at the controller, the actual context information with the simulated context information to determine whether the simulated context information corresponds with the actual context information within predetermined limits; and requesting updated context information from the unit to be controlled if the simulated context information is outside the predetermined limits with respect to the actual context information at the given point in time, the controller requesting the updated context information, wherein the controller repeatedly requests updated context information according to an update frequency, and the update frequency is decreased if the first and second variables match or increased if the first and second variables do not match.
