摘要： A method for controlling knocking of an internal combustion engine in which a knocking signal and a combustion signal are formed by directing vibrations detected by a vibration sensor through a primary filter circuit including a combustion filter circuit and a knocking filter circuit. The combustion filter circuit and knocking filter circuit each include a time gate and a filter. A ratio of a representative value of the knocking signal to a representative value of the combustion signal is obtained and used to decide whether knocking is occurring. The output voltage of control signals generated based on the decision that knocking is occurring may be varied as a function of the strength of the knocking and/or the frequency of the knocking.

摘要： A method for error detection during an evaluation of sensor signals, in particular during an evaluation of output signals of knock sensors in an internal combustion engine, with at least one sensor and an evaluating device connected therewith, the method includes the steps of forming at least one variable reference level from output signals of a sensor or sensors; comparing the variable reference level for error detection with upper and/or limiting values; making a conclusion about an error in the case of a predeterminable exceeding of the upper and/or exceeding of the lower limiting value by the actual reference level; and forming at least one limiting value in dependence on preceding reference values.

摘要： A knock control apparatus has a knock sensor and a signal processor. The signal processor integrates a knock sensor signal and differentiates the integrated signal. The signal processor detects a period in which the differentiated signal exceeds a threshold, and detects a peak of the differentiated signal. The signal processor then calculates a ratio between the detected signal generation period and the detected peak to determine a knock when the calculated ratio is within a predetermined range. Alternatively, the signal processor detects a peak generation time and calculates a ratio between the detected signal generation period and the detected peak generation time. In this instance, the signal processor determines the knock when the calculated ratio is within a predetermined range and the detected peak generation time is less than a predetermined time reference.
