Look-up tables are used in a great variety of fields; their simple structure makes them a common choice for non-linear models. In automotive applications, engine control unit (ECU) software includes many 1-D and 2-D look-up tables. These tables need to be calibrated with expert engineer during long hours of testing. The look-up tables might require being created from the measurement data, or they might require being updated due to several reasons. A simple and fast mathematical approach is introduced in this work for these requirements. The algorithm is applied to a soot emission measurement data, which is provided from FEV Europe GmbH. It is demonstrated that the created generic look-up table results in the low amount of error. In addition to details of the algorithm, and the simulation demonstration; further improvements and other possible applications of the approach is given throughout the paper.
