ENGINE COMBUSTION NOISE FEEDBACK CONTROL METHOD BASED ESTIMATION OF ENGINE VIBRATION SIGNAL

摘要

The present invention relates to an engine combustion noise feedback control method based on estimation of an engine vibration signal. According to an engine combustion noise feedback control method based on estimation of an engine vibration signal, an engine combustion noise estimation value following a predetermined engine combustion noise target value is estimated by an engine vibration signal to be continuously changed. Thus, the engine combustion noise estimation value with respect to the engine combustion noise target value can accurately follow the engine combustion noise target value with feedback control changed by a first, second, and n_th engine combustion noise estimation value, and more specifically, a high-priced combustion pressure sensor to detect combustion pressure needs not to be used.
