Engine Combustion Noise Feedback Control Method based Estimation of Engine Vibration Signal

摘要

In the soft noise feedback control method predicted by the engine vibration signal of the present invention, the soft noise feedback control method predicted by the engine vibration signal is continuously changed by predicting the engine soft noise estimate value following the set engine noise reduction target value The engine combustion noise estimation value for the engine combustion noise target value is feedback control which is changed to the first, second, ... n engine combustion noise estimation value, and the accuracy of the engine combustion noise target value follow-up is made, The use of the combustion pressure sensor is unnecessary.
