    摘要: A start quantity adaptation value (ST_AD) is adapted as a function of a variable that is characteristic of a rotational speed profile during the start (ST) of the internal combustion engine. A lambda adaptation value (LAM_AD) is adapted as a function of at least one control parameter (LAM_RP) of the lambda controller if a preset condition (COND) is met, which presupposes the existence of a quasi-stationary operating state. An intermediate correction value (ZW_KOR) is adapted as a function of a change of the start quantity adaptation value (ST_AD) since a last adaptation of the lambda adaptation value (LAM_AD). A fuel mass (MFF) to be metered is determined as a function of at least one operating variable (BG) of the internal combustion engine. The fuel mass (MFF) to be metered is corrected during the start (ST) of the internal combustion engine by means of the start quantity adaptation value (ST_AD). The fuel mass (MFF) to be metered outside of the start (ST) of the internal combustion engine is corrected as a function of the lambda adaptation value (LAM_AD). The fuel mass (MFF) to be metered is corrected as a function of the intermediate correction value (ZW_KOR) until for the first time after the respective start (ST) the lambda adaptation value (LAM_AD) is adapted.

    摘要: For operating an internal combustion engine a respective Lambda adaptation value (LAM_AD) assigned to a respective temperature range is adapted as a function of at least one corrective signal proportion of the Lambda controller in relation to a control parameter of the Lambda controller if a respective predetermined condition is fulfilled which requires that a quasi-stationary operating state obtains and the respective temperature range is adopted. The respective Lambda adaptation value (LAM_AD) is assigned a respective reference temperature in the respective temperature range. if a predetermined test condition is fulfilled, a check is made as to which of the Lambda adaptation values (LAM_AD) was adapted as a function of the at least one corrective signal proportion since the test condition was last fulfilled. a respective Lambda adaptation value not adapted as a function of the at least one corrective signal, which in relation to a respective assigned temperature range is adjacent to a respective Lambda adaptation value adapted as a function of the at least one corrective signal proportion, is checked as to whether it lies in a range of valid values, which in relation to the reference temperature of the respective adjacent adapted Lambda adaptation value, diverges in a predetermined manner starting from the respective adapted Lambda adaptation value. If it lies outside the predetermined diverging range of valid values, the non-adapted Lambda adaptation value (LAM_AD) is adapted, so that it lies approximately on the boundary of the closest range of valid values in relation to its value before the adaptation.

    摘要: When the lambda controller is active (LAM ACT), in the cold operating state (STATE COLD) and in the presence of a predefined first condition, a present cold adaptation value (AD COLD AV) is determined and the present cold adaptation value (AD COLD AV) is assigned a valid cold adaptation value (AD COLD VLD). When the lambda controller is active (LAM ACT), in the warm operating state (STATE WARM) and in the presence of a predefined second condition, a present warm adaptation value (AD WARM AV) is determined and assigned a valid warm adaptation value (AD WARM VLD). In addition, the valid cold adaptation value (AD COLD VLD) is adapted in the presence of a predefined third condition as a function of a difference (AD WARM DELTA) between the valid warm adaptation value (AD WARM VLD) and the present warm adaptation value (AD WARM AV).
