Abstract:
A knock control apparatus for an internal combustion engine includes a knock signal normalization portion that normalizes a knock signal using base statistics calculated on the basis of the knock signal. The knock signal normalization portion calculates base statistics on the basis of a last value and a current value of the knock signal and normalizes the knock signal using a base statistic interpolated according to an operating state.
