Claim One:
1. A method for calibrating a control unit of an internal combustion engine, the method comprising: optimizing a plurality of target functions that include NO x target function, soot target function and fuel consumption target function and which are a function of variation variables of a multicriteria optimization problem, the multicriteria optimization problem providing a set of possible optimal solutions as a result, evaluating the possible optimal solutions of the multicriteria optimization problem to select one of the possible optimal solutions as a selected solution for calibration, wherein, during the evaluating, the set of possible optimal solutions of the multicriteria optimization problem is displayed in a model space as a two- or three-dimensional diagram of the plurality of target functions, and at the same time at least one of the plurality of target functions is displayed in a variation space as a function of at least one variation variable, and wherein the model space and the variation space are interactively linked by marking, for each selected solution in the model space, the variation variable in the variation space upon which the selected solution is based.
