Abstract
A method for checking the function of an engine system having an internal combustion engine includes: (a) ascertaining a first charge adaptation value for acting on a manipulated variable for setting an air supply to the internal combustion engine, and ascertaining a first mixture adaptation value for acting on a manipulated variable for setting a fuel supply at a predefined first operating point of the internal combustion engine, in each case with the aid of a predefined adaptation method; and (b) establishing that an error is present in the engine system when at least one of the offset adaptation values is outside a particular predefined adaptation value range.
Claims11
A method for checking the function of an engine system having an internal combustion engine, comprising:
- performing, at a predefined first operating point of the internal combustion engine, the following with the aid of a predefined adaptation process:
- ascertaining a first charge adaptation value which acts on an associated manipulated variable for setting an air supply to the internal combustion engine, and
- ascertaining a first mixture adaptation value which acts on an associated manipulated variable for setting a fuel supply;
- and
- determining that an error is present in the engine system if at least one of the first charge adaptation value and the first mixture adaptation value is outside a predefined adaptation value range.
A device for checking the function of an engine system having an internal combustion engine, the device comprising:
- means for performing, at a predefined first operating point of the internal combustion engine, the following with the aid of a predefined adaptation process:
- ascertaining a first charge adaptation value which acts on an associated manipulated variable for setting an air supply to the internal combustion engine, and
- ascertaining a first mixture adaptation value which acts on an associated manipulated variable for setting a fuel supply;
- and
- means for determining that an error is present in the engine system if at least one of the first charge adaptation value and the first mixture adaptation value is outside a predefined adaptation value range.
A non-transitory computer-readable storage medium storing a computer program having program codes which, when executed on a computer, performs a method for checking the function of an engine system having an internal combustion engine, the method comprising:
- performing, at a predefined first operating point of the internal combustion engine, the following with the aid of a predefined adaptation process:
- ascertaining a first charge adaptation value which acts on an associated manipulated variable for setting an air supply to the internal combustion engine, and
- ascertaining a first mixture adaptation value which acts on an associated manipulated variable for setting a fuel supply;
- and
- determining that an error is present in the engine system if at least one of the first charge adaptation value and the first mixture adaptation value is outside a predefined adaptation value range.
