Abstract
A system for detecting knock using an Autoregressive Integrated Moving Average (ARIMA) model. The system includes an electronic processor. The electronic processor is configured to receive a signal from a knock sensor and using the ARIMA model, determine constituents of the signal, wherein the constituents include a residual constituent. The electronic processor is also configured to determine, based on an amplitude of the residual constituent, whether a combustion is a knocking combustion or a non-knocking combustion.
