    摘要: The apparatus of the present invention corrects a control target value of ignition timing using a multipoint learned value AGdp(n) for compensating for a change amount of the ignition timing caused by time-dependent change of the engine and a basic learned value AG(i) for compensating for a change amount of the ignition timing caused by a factor other than the aforementioned time-dependent change of the engine. In a multipoint learning range n in which the time-dependent change of the engine influences the ignition timing to a great extent, the control target is corrected using the multipoint learned value AGdp(n) and the basic learned value AG(i). In ranges other than the multipoint learning range n, the control target is corrected using only the basic learned value AG(i). Normally, only the learning of the multipoint learned value AGdp(n) is permitted in the multipoint learning range n, and only the learning of the basic learned value AG(i) is permitted in the ranges other than the multipoint learning range n. When it is determined that there is a possibility that fuel has been fed to a fuel tank, the learning of the multipoint learned value AGdp(n) is prohibited for a subsequent predetermined period (if NO in step S103 or step S104).

    摘要: A 90° integrated value calculating unit of an engine ECU calculates a 90° integrated value obtained by integrating a magnitude. A calculating unit calculates a knock magnitude by dividing 90° integrated value by a BGL. A value obtained by subtracting a standard deviation σ from a median value of 90° integrated value is determined as the BGL. An ignition timing control unit controls the ignition timing depending on whether knock magnitude is equal to or larger than a determination value. A median value calculating unit calculates median value of 90° integrated value. A standard deviation calculating unit calculates standard deviation of 90° integrated value. A first stop unit stops updating of median value and standard deviation when 90° integrated value is smaller than a first threshold value or is equal to or larger than a second threshold value.

    摘要: A switching element is controlled by a control circuit. When the switching element is in an ON state, a coil current I.sub.L ramps up. When the switching element is in an OFF state, the coil current I.sub.L ramps down. If an output voltage V.sub.out is smaller than a predetermined output voltage value, a control circuit is informed of it. If the coil current I.sub.L rises to a peak current I.sub.LP set by a setting circuit, the control circuit is informed of it. The setting circuit sets the peak current I.sub.LP proportional to an input voltage V.sub.in. The control circuit sets the switching element in the ON state when the output voltage V.sub.out is smaller than the predetermined output voltage value, and sets the switching element in the OFF state when the coil current I.sub.L rises to the peak current I.sub.LP.

    摘要: An output signal of a knock sensor is filtered with a plurality of band-pass filters to extract vibration waveform components of a plurality of frequency bands (f1-f4). Weighting coefficients (G1-G4) which multiply the vibration waveform component of each frequency band are established in such a manner as to be a small value as a noise intensity of each frequency band becomes larger. Thereby, the vibration waveform component of a plurality of frequency bands is synthesized by weighting according to an influence of a noise intensity of each frequency band. Even when the noise is superimposed on the vibration waveform component of any of the frequency bands, it becomes possible to reduce the influence of the noise and to synthesize the vibration waveform component of each frequency band, and an accurate knock determination can be performed based on the composite vibration waveform.
