Abstract
A method is provided for controlling knock on an internal combustion engine. The method includes the steps of determining a maximum value of knock and determining whether conditions are right for updating the maximum value of knock. The method also includes using an unmodified spark advance if conditions are not right for updating the maximum value of knock and modifying the spark advance if conditions are right for updating the maximum value of knock.
