Abstract: A method and apparatus for controlling an internal combustion engine having a first actuator for influencing the gas air mass flow delivered to the internal combustion engine, having a second actuator for influencing the high-pressure-side recirculated exhaust gas mass flow, and having at least one third actuator for influencing the low-pressure-side recirculated exhaust gas mass flow, a first actuating variable for the first actuator being predefinable based on a comparison between a first setpoint and a first actual value for the fresh air mass flow and/or on further modeled or measured variables, a second actuating variable for the second actuator being predefinable based on a comparison between a second setpoint and a second actual value for the high-pressure-side exhaust gas mass flow and/or on further modeled or measured variables, and at least one third actuating variable for the at least one third actuator being predefinable based on a comparison between a third setpoint and a third actual value for t

Abstract: In a method and device for operating an internal combustion engine having an adjustable component through which a gas flows and by whose setting the gas flowing through the component is influenced, at least one first value representative of a flow-through area of the component is determined in accordance with a first model as a function of a triggering signal of the component, at least one second value representative of the flow-through area of the component is determined in accordance with a second model as a function of at least one performance quantity of the internal combustion engine different from the triggering signal, and a resulting value is formed for the flow-through area as a mean of the at least one first value and the at least one second value.

Abstract: A method and a device for operating an internal combustion engine, e.g., of a motor vehicle, may permit a most accurate possible determination of a value for the flow-through area, e.g., the effective flow-through area, of a component arranged in a gas channel. The internal combustion engine has an adjustable component through which a gas flows and by whose setting the gas flowing through is influenced. At least one first value representative of a flow-area of the component, e.g., the effective flow-through area, is determined in accordance with a first model as a function of a triggering signal of the component. At least one second value representative of the flow-through area of the component, e.g., the effective flow-through area, is determined in accordance with a second model as a function of at least one performance quantity of the internal combustion engine different from the triggering signal. A resulting value is formed for the flow-through area, e.g.
