Abstract
A method for controlling engine knocking, in which a retarded timing is recovered based on a retarded timing amount learned when the engine knocking occurs during driving of a vehicle, includes a first process of retarding an ignition timing based on the previously learned retarded timing amount in a reference engine operating condition entered during driving of the vehicle. A second process recovers the retarded timing when a first condition in which a time duration acquired by accumulating a driving time under the reference engine operating condition is equal to or more than a reference time duration and a second condition in which the engine knocking does not occur while driving under the reference engine operating condition are satisfied.
