    摘要： A computer-implemented platform may comprise hardware and software configured to manage an engine using knock intensity data. Knock intensities from a plurality of combustion cycles may be used to estimate a statistical distribution of knock intensities. The distribution of knock intensities may be used to determine a Descriptive Statistic, which may represent a state of tune of the engine. A calculated Descriptive Statistic may be compared to a desired Descriptive Statistic (e.g., that is representative of operation during a desired tune state of the engine). A deviation between the calculated and desired knock intensity distributions (e.g., between the calculated DS and desired DS) may be used to adjust a control parameter of the engine. Adjustment may be engine-wide. Adjustment may be cylinder-by-cylinder.

    摘要： A method of real-time estimation of the intensity of the knocking of an internal combustion engine utilizing a vibratory sensor is disclosed which is useful for control of internal combustion. A vibratory signal representing vibrations of the engine is continuously acquired as a function of the crankshaft angle. A model of a wave equation propagating through the cylinder-head is constructed. The coefficients of a Fourier decomposition of the vibratory signal are determined in real time by inverting the dynamics of the wave equation model using an estimator. The energy contained in the signal is computed by summing the squares of the coefficients of the Fourier decomposition. A parameter correlated with the intensity of knocking equal to the square root of the maximum of the energy is determined in real time.

    摘要： A method and a device are provided for knock recognition of an internal combustion engine, which device Fourier-transforms, weights in frequency-dependent fashion, and sums a signal of a knock sensor in order to produce a first knock signal. Here, from a multiplicity of first knock signals, a concentration point of the multiplicity of the first knock signals is determined, and a first offset value is subtracted from the first knock signal in order to form a second knock signal, the first offset value being ascertained from the concentration point of the multiplicity of the first knock signals, and a second knock signal that has a value below zero being set to the value zero. The further-processed second knock signal is then evaluated as knocking or non-knocking.
