摘要： 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.

摘要： A method for operating a system having an internal combustion engine and an exhaust aftertreatment system having an SCR catalyst, wherein the internal combustion engine is controlled on the basis of at least one process parameter that influences a nitrogen oxide raw emission, wherein aging detection is performed for the SCR catalyst, wherein in a first operating mode of the internal combustion engine, if aging of the SCR catalyst is detected, the at least one process parameter is changed in the direction of a reduced nitrogen oxide raw emission, wherein the internal combustion engine is controlled on the basis of the changed at least one process parameter.

摘要： A method for determining the aging of an oxidation catalyst in an exhaust gas aftertreatment system of an internal combustion engine, having the following steps: ascertaining a soot burn rate of a particle filter of the exhaust gas aftertreatment system; adapting a function having at least one adaptation parameter to the soot burn rate dependent on at least one variable, a value of the adaptation parameter depending on an aging of the oxidation catalyst; and determining the aging of the oxidation catalyst using the adaptation parameter value ascertained by adapting the function.

摘要： A method for regulation of an internal combustion engine with an SCR catalytic converter in which the operating point of the engine is predefined by an engine control unit and the operating point of the catalytic converter is predefined by an SCR control unit. An overall system quality measure is calculated by an optimizer in accordance with fed back values of the engine control unit and fed back values of the SCR control unit, by changing the default values for the engine control unit and the SCR control unit, the optimizer minimizes the overall system quality measure for a prediction horizon regarding operating costs. On the basis of the minimized overall system quality measure the optimizer sets the default values for the engine control unit and the default values for the SCR control unit as decisive for setting the operating point of the engine and the catalytic converter.

摘要： A method for the model-based control and regulation of an internal combustion engine. The method includes calculating, as a function of a set torque, injection system set values for controlling the injection system actuators via a combustion model and calculating gas path set values for controlling the gas path actuators via a gas path model. The combustion model is adapted during operation of the internal combustion engine into the form of a complete data-based model. A measure of quality is minimized by an optimizer by changing the injection system set values and gas path set values within a prediction horizon, and the injection system set values and gas path set values are set by the optimizer, which is critical for adjusting the operating point of the internal combustion engine by using the minimized measure of quality.

摘要： A method for model-based control and regulation of an internal combustion engine. An emission class for operating the engine is read from a first library by an optimizer; a maximum mechanical component load is read from a second library by the optimizer using the engine type; and the emission class and the component load are set as mandatory for a combustion model and a gas path model. Injection system target values for actuating injection system actuators are calculated using the combustion model based on a target torque. Gas path target values for actuating gas path actuators are calculated using the gas path model based on the target torque. A quality measurement is calculated by the optimizer based on the injection system and gas path target values. The quality measurement is minimized by the optimizer by changing the injection system and gas path target values within a prediction horizon. The injection system and gas path target values are set as decisive for adjusting the operating point of the engine by the optimizer using the minimized quality measurement.

摘要： 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.
