Abstract:
1. A computer implemented method for the automatic determination of a quality of a transition compensation, the transition compensation bringing about an at least partial compensation of the effect of a wall film effect in a control and regulation of a gasoline engine, the method comprising: a control device automatically recording a characteristic of Lambda values and load in a test phase during an operation of the gasoline engine having activated transition compensation; the control device automatically extracting relevant load changes as a function of the determined characteristics, a load change describing a change from a first load to a second load that differs from the first load; the control device automatically implementing a classification of the extracted load changes as a function of specifiable classification criteria, and assigning at least one Lambda value to each of the load changes; the control device automatically determining a quality value for each of extracted load changes as a function of a deviation of the at least one assigned Lambda value from a specifiable setpoint Lambda value; the control device automatically weighting the determined quality values with respect to a classification of the assigned load changes; and the control device automatically determining an overall quality as a function of the weighted quality values using at least one statistical method.
