Abstract
Various embodiments include a method for determining the temperature of an engine oil in an internal combustion engine comprising: acquiring a value of a parameter characterizing a current operating point of the internal combustion engine; and calculating the temperature of the engine oil using an oil temperature model. The oil temperature model depends at least in part on dilution of the engine oil caused by different components in the engine oil and accounts for modified heating behavior of the engine oil based on the dilution.
