Abstract
A control device for an internal combustion engine includes: a flow path module which is configured for: receiving a specified value for a flow path parameter of a flow path of the internal combustion engine; and determining a control specification for a control element of the flow path depending on the specified value using at least one component characteristic map of at least one component of the flow path.
Claims15
A control device for an internal combustion engine, the control device comprising:
- a flow path module which is configured for:
- receiving a specified value for a flow path parameter of a flow path of the internal combustion engine;
- and
- determining a control specification for a control element of the flow path, the control specification being determined depending on the specified value and being determined using at least one component characteristic map, the at least one component characteristic map being of at least one component of a bypass of the flow path, the bypass bypassing a high pressure turbine of an exhaust gas turbocharger upstream of a low pressure turbine of another exhaust gas turbocharger;
- and
- a higher-level control module that is configured for determining the specified value and for passing the specified value to the flow path module, the flow path module being further configured for delivering at least one feedback to the higher-level control module, wherein the at least one feedback is selected from at least one limiting value and at least one limiting curve.
