A method for detecting abnormal combustion in the combustion chamber of at least one cylinder of a spark-ignition supercharged internal-combustion engine includes: measuring a quantity linked with the combustion of the fuel mixture in the chamber, producing a signal whose amplitude depends on the amplitude of the measured quantity, comparing the amplitude of the signal produced with the amplitude of a threshold signal corresponding to the amplitude of a signal during combustion with engine knock, determining the presence of a rumble type abnormal combustion in the combustion chamber when the amplitude of the signal produced exceeds the amplitude of the threshold signal by a significant value.
