A method for controlling and regulating an internal combustion engine with exhaust gas recirculation, in which an EGR rate is determined by a Kaiman filter from calculated and measured variables of the gas path and from calculated and measured variables of combustion. A method for the model-based control and regulation of an internal combustion engine includes calculating injection system set values for controlling the injection system actuators as a function of a set torque by a combustion model. Gas path set values for controlling the gas path actuators are calculated as a function of an EGR rate by a gas path model. A measure of quality is calculated by an optimizer as a function of the injection system and gas path set values. The measure of quality is minimized by the optimizer by changing the injection system and gas path set values within a prediction horizon. The injection system and gas path set values are set by the optimizer as definitive for adjusting the operating point of the engine by using the minimized measure of quality.

A method for providing a position of at least one object, including receiving surrounding area data values, the surrounding area data values representing a surrounding area of an infrastructure installation, the surrounding area including the at least one object, receiving status data values, the status data values representing a status of the infrastructure installation, determining the position of the at least one object in the surrounding area on the basis of the surrounding area data values and as a function of the status of the infrastructure installation, and providing the position of the at least one object. A device is also provided.

A method for model-based open-loop and closed-loop control of an internal combustion engine, in which method injection system setpoint values for activating the injection system control elements are calculated dependent on a setpoint torque by a combustion model, and gas path setpoint values for activating the gas path control elements are calculated by a gas path model. The combustion model is adapted during ongoing operation of the internal combustion engine. A quality measure is calculated by an optimizer dependent on the injection system setpoint values and the gas path setpoint values, the quality measure is minimized by the optimizer by varying the injection system setpoint values and gas path setpoint values within a prediction horizon. The injection system setpoint values and gas path setpoint values are set by the optimizer, based on the minimized quality measure, as being definitive for setting of the operating point of the internal combustion engine.

A method for predictive open-loop and/or closed-loop control of an internal combustion engine with control variables pursuant to a model of the engine with characterizing variables and a control circuit for the control variables. The control variables are adjusted in an open-loop or closed-loop manner by measuring actual values and specifying target values of the characterizing variables and, optionally, depending on the boundary and/or environmental and/or ageing conditions. The characterizing variables are controlled pursuant to a model of the engine with the characterizing variables and a control circuit with the control variables. The controlling is part of a model-based predictive control, wherein the characterizing variables of the engine model are calculated and the control variables of the engine are adjusted in a predictively controlled manner. A model-based predictive non-linear controller is used for the controlling, which is constructed in a modular manner with a number of model-based predictive control modules.
