Abstract
A method and a control module for performing the same include a filter module filtering in-cylinder pressure signals using a filter to form filtered in-cylinder pressure signals. The control module further includes a heat release rate determination module generating heat release rate signals based on the in-cylinder pressure signals and a maximum heat rate determination module determining a maximum heat release rate from the heat release rate signals. The system also includes a correction module correcting auto-ignition for the engine based on the maximum heat release rate.
