Abstract

A method for regulating an internal combustion engine where engine measurement and engine adjustment values is provided, and adaptation values modify the engine parameters, comprising measuring a first engine measurement parameter representative of a first physical engine parameter, measuring a second engine measurement parameter representative of a second physical engine parameter, calculating a first estimation parameter via a first engine parameter, calculating a second estimation parameter via a second engine parameter, determining a first operating mode of the engine regulation method, the first operating mode determined by generating a first adaptation value based on the first engine parameter, generating a second adaptation value based on the second measurement parameter, and comparing the percent difference of the first and second adaptation values to a neutral value of the respective engine parameter, and determining a second operating mode of the engine regulation method.
