Abstract
This invention relates to a method for knock detection in a combustion engine, in which combustion is controlled by a control unit (), which comprises the steps of, a) obtaining at least one sensor signal (') carrying information of knock intensity related within a combustion chamber of the combustion engine (); (b) processing the sensor signal (′) to obtain a knock intensity related detection variable (z), (c) using said detection variable (z) in said control unit () arranged to avoid a knocking condition in said combustion engine (), if the value (z) of said detection variable indicates knock when compared with a threshold value (T) wherein using two different computations/processes for said processing () of the at least one sensor signal (′) to obtain two separate sub-values (y, y), and thereafter combining said sub-values (y, y) to obtain said detection variable (z).
