Abstract
Internal combustion engine ignition timing is adjusted in response to a sensed knock condition and in response to a determination of engine knock propensity through application of fuzzy logic, wherein an inference engine comprised of a predetermined knowledge rulebase generates a set of truths in response to application of a set of input signals from a set of membership functions. The set of truths are combined according to both relative and absolute strength in indicating engine knock propensity.
